Technical Field

The application relates to the technical field of containers, in particular to a system and a method for measuring the melt liquid level in a container.

Background

The related art level gauge can be used to measure the level of a part of a container, but the related art level gauge has a very limited application, for example, the level of a cold crucible used in a cold crucible glass solidification technology cannot be measured.

The cold crucible glass solidification technology has the characteristics of high working temperature, wide treatment range, long service life, uniform melt, small equipment volume, easy retirement and the like. The cold crucible glass solidification technology can be used for low and medium level radioactive wastes such as solid wastes, resin, concentrates and the like generated by a nuclear power station; it can also be used for high-level radioactive waste liquid and other wastes which are hard to treat and have strong corrosiveness. Therefore, the development of this technology has received much attention. In nuclear power operation, a large amount of radioactive waste must be produced. The spent fuel post-treatment and the high-level radioactive waste liquid generated by the spent fuel post-treatment have the characteristics of high radioactivity ratio, high heat release rate, containing some nuclides with long half-life period and high biological toxicity and the like, so the treatment and the disposal of the spent fuel become one of the key problems for restricting the sustainable development of nuclear power and nuclear fuel cycle industry. The cold crucible glass solidification technology is a new nuclear waste treatment technology, and has unique advantages in the aspects of nuclear waste and high-level radioactive waste liquid treatment.

The cold crucible is a circular or oval container composed of a plurality of arc blocks or pipes, cooling water is introduced into the arc blocks or pipes to keep a cold wall, gaps among the arc blocks or pipes are filled with insulating substances, the materials in the cold crucible are heated through an electromagnetic field, and a water-cooling coil formed by winding a copper pipe is arranged outside the cold crucible. Because the cold crucible adopts a water cooling structure, a solid glass shell layer can be formed in a region close to the cooling pipe with low temperature, and the corrosion of the melt to the cold crucible is avoided. The cold crucible glass curing system mainly comprises: the system comprises a cold crucible, a feeding subsystem, a glass discharging subsystem, a flue gas purification subsystem, an instrument control system and the like. The cold crucible glass solidification process mainly has three forms, which are respectively as follows: a two-step glass curing process, a one-step glass curing process and a one-step burnt glass curing process. The two-step glass curing process is that waste liquid is calcined in a calcining furnace and then mixed with glass base material, and the mixture is sent to a cold crucible; the one-step glass curing process is that the waste liquid and the glass base material are directly sent into a cold crucible; the one-step glass burning and solidifying process includes mixing solid combustible waste with glass base material and feeding the mixture into cold crucible. The first two processes are mainly used for treating waste liquid, and the latter process is mainly used for treating solid waste.

The cold crucible is mainly composed of a water-cooled crucible, a power supply and other auxiliary facilities. The crucible is wound with a spiral induction coil, and the induction coil is connected with a power supply to generate an alternating electromagnetic field. When the coil was energized with an alternating current, 1 alternating electromagnetic field was generated inside and around the coil. Since each metal tube of the cold crucible is insulated from each other, an induced current is generated in each tube. When the instantaneous current of the induction coil is in the anticlockwise direction, the induced current in the clockwise direction is simultaneously generated in the section of each tube, the current directions on the sections of two adjacent tubes are opposite, the directions of the magnetic fields established between the tubes are the same, and the magnetic field enhancement effect is outwards expressed. Therefore, each gap of the cold crucible is provided with 1 strong magnetic field, the cold crucible is like a current booster and gathers magnetic lines of force on materials in the crucible, and the materials in the crucible are cut by the magnetic lines of force of the alternating magnetic field. According to the electromagnetic field theory, induced electromotive force is generated in the material in the crucible, and a closed current loop is formed in a thin layer on the surface of a melt of the material due to the existence of the induced electromotive force. This current is usually called eddy current, and the cold crucible technology is based on the eddy current to heat and process the material.

The cold crucible can heat the material into a melt, and the measurement of the liquid level of the melt has a great influence on the running state of the cold crucible and the like in the running process of the cold crucible. Meanwhile, for special fields such as glass solidification of radioactive wastes, it is required that the corresponding measuring device cannot be deeply inserted into the melt and that the measuring device is fast and sensitive in response. However, the related art is not effective in measuring the level of the melt in the cold crucible.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be described below in detail and completely with reference to the accompanying drawings of the embodiments of the present application. It should be apparent that the described embodiment is one embodiment of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the application without any inventive step, are within the scope of protection of the application.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.

The embodiment of the present application first provides a system for measuring the melt level in a container 100, and fig. 1 is a schematic structural diagram of the container 100 according to an embodiment of the present application.

The vessel 100 may include a heating element defining a heating chamber having an opening for heating the material into a melt, and a cover (not shown) for opening and closing the opening.

It can be understood that the container 100 can be a cold crucible, and the cold crucible is a crucible that uses a power supply to generate a high-frequency current, and then converts the high-frequency current into an electromagnetic current through an induction coil (which can be a high-frequency induction coil) to penetrate into the material to be heated to form an eddy current to generate heat, so as to realize the direct heating and melting of the material. The heating element of the cold crucible is a container formed by metal arc blocks or tubes which are filled with cooling water, the shape of the container is mainly circular or oval, the cooling water is continuously filled in the metal tube when the cold crucible works, the temperature of the fusant in the cold crucible can reach more than 2000 ℃, but the wall surface of the heating element still keeps lower temperature (generally less than 200 ℃), so that the materials form a solid shell in a low-temperature area on the inner wall surface of the heating element in the operation process. The cold crucible does not need refractory material, need not electrode heating, and the solid-state shell of formation can reduce the corrosive action of material to the cold crucible, prolongs the life of cold crucible for the cold crucible can be handled corrosive material, and wherein, the discharge opening of cold crucible can be located the bottom in heating chamber.

When the cold crucible works, the induction coil is electrified with alternating current, and an alternating electromagnetic field is generated inside and around the induction coil. Because the metal tubes of the cold crucible are insulated from each other, induced current is generated in each metal tube, the current directions on the cross sections of the two adjacent metal tubes are opposite, the magnetic fields established between the metal tubes are the same in direction, and the magnetic field enhancement effect is realized outwards. Therefore, each gap of the cold crucible is provided with a strong magnetic field, the cold crucible is like a current booster and gathers magnetic lines of force on materials in the cold crucible, the materials in the cold crucible are cut by the magnetic lines of force of the alternating magnetic field, induced electromotive force is generated in the materials in the cold crucible, a closed current loop is formed in a thin layer on the surface of a melt of the materials due to the existence of the induced electromotive force, and a large amount of heat is generated by the eddy current loop, so that the materials are melted.

The cold crucible can be used for a two-step glass solidification process, in the two-step glass solidification process, a radioactive material to be treated is pretreated in a rotary calcining furnace, the liquid state is converted into a slurry or solid powder state, then the pretreated material and a glass base material are added into the cold crucible together, and the glass is melted in the cold crucible, so that the harm of radioactive substances to the environment can be avoided.

The level of the melt in the vessel 100 directly affects the operation state of the vessel 100, for example, when the level is too low, the waste of heating resources is likely to occur, and when the level is too high, the heating effect is also likely to be reduced, so that more melt is solidified and the discharge is difficult. When the container 100 is a cold crucible, the liquid level is too low, the melt can deviate from the main power area of the induction coil, the utilization rate of the cold crucible to energy is reduced, the temperature of the melt is reduced, the melting speed is reduced, and the melting activity is reduced. When the liquid level in the cold crucible is too high, the region of high-temperature melting is far away from the crucible bottom of the cold crucible, so that the temperature of the bottom of the melt is low, the discharging is extremely difficult, and even the condition that the discharging cannot be carried out is caused. Therefore, the liquid level height in the crucible needs to be monitored in real time during the running of the cold crucible, and the liquid level is kept in a proper height interval, so that even if the cold crucible is kept at higher melting activity, the hot zone cannot be too far away from the crucible bottom to influence the discharging of the cold crucible.

Because of the special high temperature environment in the heating chamber 110 of the cold crucible, and the material processed by the cold crucible may be radioactive corrosive material, it is difficult to provide some liquid level detection devices in the heating chamber to measure the liquid level, and the measurement system 200 provided in the embodiment of the present application can be applied to the cold crucible.

The system 200 for measuring the level of a melt in a vessel 100 provided by embodiments of the present application includes a gas source 210, a gas inlet tube 220, a gas outlet tube 230, and a gas measuring device 240.

The gas source 210 is used for generating gas flow when the measuring system 200 measures the liquid level; a first end of the air inlet pipe 220 is connected with the air source 210; the outlet pipe 230 is communicated with the inlet pipe 220, so that when the second end of the inlet pipe 220 is sealed by the melt, the airflow enters the outlet pipe 230 from the inlet pipe 220, when the second end is not sealed by the melt, part of the airflow enters the outlet pipe 230 from the inlet pipe 220, and the other part of the airflow is discharged from the second end; the gas measuring device 240 is used for measuring the gas pressure and/or the gas flow rate in the gas pipe 230, and it is understood that the gas measuring device 230 may be a barometer when the gas measuring device 230 is used for measuring the gas pressure in the gas pipe 220, the gas measuring device 230 may be a flow meter when the gas measuring device 230 is used for measuring the gas flow rate in the gas pipe 220, and the gas measuring device 230 may be a combination of a barometer and a flow meter when the gas measuring device 230 is used for measuring the gas pressure and the gas flow rate in the gas pipe 220.

In some embodiments of the present application, the air inlet pipe 220 and the air outlet pipe 230 are two independent pipes, the air inlet pipe opening has been opened to the air inlet pipe 220, the air outlet pipe opening has been opened to the air outlet pipe 230, communicate through communicating pipe between the air inlet pipe 220 and the air outlet pipe 230, wherein, the junction of the air inlet pipe 220 and the communicating pipe can be provided with a sealing member, so that the air inlet pipe 220 and the communicating pipe are in sealed connection, the junction of the air outlet pipe 230 and the communicating pipe can also be provided with a sealing member, so that the air outlet pipe 230 and the communicating pipe are in sealed connection. This connection of the inlet pipe 220 and the outlet pipe 230 facilitates manufacturing.

In other embodiments of the present application, the air inlet pipe 220 is integrally disposed with the air outlet pipe 230, specifically, a partition plate is disposed in the integral pipe, the partition plate divides the inner space of the integral pipe into a first pipe cavity and a second pipe cavity, a portion of the integral pipe forming the first pipe cavity and the partition plate constitute the air inlet pipe 220, a portion of the integral pipe forming the second pipe cavity and the partition plate constitute the air outlet pipe 230, and in some embodiments, the second end of the air inlet pipe 220 is communicated with the air outlet pipe 230. The provision of the inlet tube 220 and the outlet tube 230 results in a lower cost measurement system 200.

When the measuring system 200 measures the liquid level, the second end moves downwards from above the liquid level of the melt, and the gas measuring device 240 indicates the position of the corresponding second end as the position of the liquid level when the gas pressure and/or the gas flow rate measured during the movement rises to a preset value.

FIG. 2 is a schematic view of a measurement system 200 in a first position during measurement according to one embodiment of the present application; FIG. 3 is a schematic view of a measurement system 200 in a second position during measurement according to one embodiment of the present application.

As shown in fig. 2 (wherein the dashed arrow indicates the flowing direction of the gas flow), when the measuring system 200 starts to measure the liquid level, the second end of the gas inlet pipe 220 is located above the liquid level of the melt, i.e., the first position shown in fig. 2 indicates that the second end of the gas inlet pipe 220 is located above the liquid level of the melt, and at this time, the gas source 210 starts to generate the gas flow from the first end of the gas pipe 220 to the second end of the gas pipe 220.

Subsequently, the second end of the air tube 220 continues to move downward, and it is understood that during this movement, the gas source 210 will continue to generate a flow of gas from the first end of the air tube 220 to the second end of the air tube 220, and the gas measuring device 230 will continue to measure the pressure and/or flow of gas within the air tube 230 during this movement.

When the second end of the gas inlet pipe 220 is not in contact with the liquid level of the melt, part of the gas flow enters the gas outlet pipe 230 from the gas inlet pipe 220, and the other part of the gas flow is discharged to the environment from the second end of the gas inlet pipe 220, so that the gas pressure and/or the gas flow in the gas outlet pipe 230 do not change too much, that is, the measurement value of the gas measurement device 240 does not change too much.

It will be appreciated that the container 100 may also have a lid for opening and closing the opening of the heating chamber, the lid allowing a small amount of gas exchange between the space inside and outside the heating chamber, and accordingly the lid is provided with an opening through which the inlet pipe 220 and the outlet pipe 230 pass for level measurement. The container 100 may further have a door body for opening and closing the opening, wherein when the measurement system 200 measures the liquid level of the melt, the door body is opened, and when the measurement system 200 does not measure the liquid level of the melt, the door body is closed, and the door body and the cover body may be hermetically connected by a sealing member, wherein the sealing member may be made of rubber or other materials.

As the second end of the inlet pipe 220 moves downward, as shown in fig. 3 (where the dashed arrow indicates the flow direction of the gas stream), the second end of the inlet pipe 220 comes into contact with the surface of the melt. At this time, the gas flow cannot flow from the second end of the gas inlet pipe 220 to the environment, and thus, the gas pressure and/or the gas flow rate in the gas outlet pipe 230 may be greatly changed. Therefore, when the gas pressure and/or the gas flow rate measured by the gas measuring device 240 during the movement rises to a preset value, it can indicate that the position of the second end of the gas inlet pipe 220 is the position of the liquid level at this time, so that the liquid level of the melt can be obtained. The specific size of the preset value can be determined according to experimental conditions.

That is, the height of the liquid level can be obtained according to the height of the second end of the air inlet pipe 220 at this time, and it can be understood that the height of the second end of the air inlet pipe 220 at this time is determined by subtracting the descending height of the second end of the air inlet pipe 220 from the initial height of the second end of the air inlet pipe 220.

In some embodiments, the position of the liquid level is used to determine a height of the melt relative to the bottom with an initial height of movement of the second end and a bottom height of the melt. It will be appreciated that the initial height of the movement and the distance of movement until the level contacts can determine the height of the level and the height of the bottom of the melt subtracted from the height of the level can determine the height of the melt relative to the bottom. Therefore, a user can conveniently and intuitively master the liquid level condition of the melt, and the user experience is improved. In other embodiments, the gas inlet tube 220 may be inserted only a small portion of the melt, typically to a depth of no more than 10cm, thereby making the readings of the gas measuring device 230 more variable than in the position shown in FIG. 3, making it easier to control the position of the second end of the gas inlet tube 220 than in the position shown in FIG. 3, and making the depth of insertion of the gas inlet tube 220 less than in the position shown in FIG. 4, reducing the stroke.

In other embodiments, the position of the liquid level is used to determine the height of the melt relative to the bottom by determining the distance the second end moves from the position of the liquid level to the bottom of the melt. Fig. 4 is a schematic view of the measurement system 200 in a third position during measurement, wherein the third position indicates that the second end of the gas pipe 220 is located at the bottom of the melt, and the gas source 210 may not generate gas flow during the movement of the second end from the position of the liquid level to the bottom of the melt, so as to save energy. Therefore, a user can conveniently and intuitively master the liquid level condition of the melt, and the user experience is improved. In other embodiments, the air may be continuously vented during the lowering of the second end of the air inlet conduit 220 to prevent material from entering the air inlet conduit 220 and causing a blockage.

The measurement system 200 may further include a driving mechanism connected to the intake pipe 220 to drive the intake pipe 220 and move the second end by driving the intake pipe 220. Therefore, the automation level of the measuring system 200 is improved, the operation burden of a user is reduced, and various data in the moving process can be determined accurately.

In some embodiments, the air inlet pipe 220 may include a horizontal pipe section and an upright pipe section, one end of the horizontal pipe section is a first end of the air inlet pipe 220, the other end of the horizontal pipe section is connected to an upper end of the upright pipe section, and a lower end of the upright pipe section is a second end of the air inlet pipe 220.

The actuating mechanism can be for the telescopic machanism who is connected with the horizontal pipe section, and actuating mechanism can stretch out and draw back to make the horizontal pipe section reciprocate, when the horizontal pipe section reciprocates, it is corresponding, the second end of intake pipe 220 also can follow and reciprocate. Such a shape of the air inlet tube 220 may facilitate the arrangement of the drive mechanism, thereby enhancing the user experience.

It can be understood that the inlet tube 220 and the outlet tube 230 may be made of stainless steel, so that when the melt is a corrosive radioactive material, the inlet tube 220 and the outlet tube 230 are not easily damaged, and the service life of the inlet tube 220 and the outlet tube 230 is prolonged.

Wherein, in some embodiments, horizontal pipe section and vertical pipe section can integrated into one piece to avoid the process of assembly, simplify production technology, promote production efficiency. In other embodiments, the horizontal pipe section and the vertical pipe section may be connected by various means such as threads and buckles, and the joint may be provided with a sealing member, thereby ensuring airtightness in the air inlet pipe 220 and thus ensuring accuracy of measurement results, wherein the sealing member may be made of a material such as rubber.

In other embodiments, the air inlet pipe 220 may only include a vertical pipe section, and the driving mechanism directly drives the vertical pipe section to move up and down, so that the air inlet pipe 220 has a simple structure and is convenient to machine and manufacture.

The measuring system 200 may further include a display device disposed outside the outlet pipe 230 for displaying the measurement result of the gas measuring device 240. When the gas measuring device 240 is arranged in the gas outlet pipe 230 to measure the gas pressure and/or the gas flow in the gas pipe 230, a user is not convenient to observe the change of the gas pressure and/or the gas flow, therefore, a display device is arranged outside the gas outlet pipe 230, so that the user can observe the observation result of the gas measuring device 240, and the user experience is improved.

In some embodiments, a display device may be affixed to the outlet tube 230 to facilitate storage of the measurement system 200. In other embodiments, the display device may be electrically connected to the gas measuring device 240 via a connection line and configured to not move with the outlet tube 230 when the outlet tube 230 moves, thereby facilitating a user to view the count of the gas measuring device 240 via the display device.

In some embodiments, the gas source 210 is further configured to generate a gas flow when the second end moves upward to separate from the liquid surface after the gas pressure and/or gas flow measured by the gas measuring device 230 rises by a preset value. That is, after the second end of the gas inlet pipe 220 is in contact with the liquid level of the melt and moves upward to be separated from the liquid level of the melt, the gas source 210 can generate a gas flow, so as to avoid a part of the melt adhering to the gas inlet pipe 220. Wherein, the intensity of the air current that produces this moment can be greater than the air current that air supply 210 produced when the second end of intake pipe 220 is by the liquid level top of fuse-element moves down, in order to improve the effect of getting rid of the attachment, thereby promote user experience, the specific size of the intensity of air current can be confirmed according to actual conditions or experimental conditions, for example, can confirm according to the liquid level of the fuse-element that measures, understandably, when the liquid level of fuse-element is higher, show that the attachment in the intake pipe 220 is more, this moment, can use in getting rid of the intensity of the air current of attachment and increase, thereby guarantee the effect of getting rid of the attachment, when the liquid level of fuse-element is lower, show that the attachment in the intake pipe 220 is relatively less, at this moment, can use in getting rid of the intensity reduction of the air current of attachment, thereby energy saving.

The measuring system 200 provided by the embodiment of the application can simply and effectively measure the liquid level of the melt in the container 100, can effectively avoid damage to the measuring system 200, and improves the user experience, and the measuring system 200 provided by the embodiment of the application for the container 100 can measure when the container 100 runs.

Embodiments of the present application also provide a method of measuring a level of a melt within a vessel 100, the method of measuring comprising: placing a second end of an air inlet pipe 220, which is connected with an air source 210 generating air flow at a first end, above the liquid level of the melt, wherein the air inlet pipe 220 is communicated with an air outlet pipe 230, so that when the second end of the air inlet pipe 220 is sealed by the melt, the air flow enters the air outlet pipe 230 from the air inlet pipe 220, when the second end is not sealed by the melt, part of the air flow enters the air outlet pipe 230 from the air inlet pipe 220, and the other part of the air flow is discharged from the second end; moving the second end downwards and measuring the gas pressure and/or gas flow in the outlet pipe 230 by using a gas measuring device 240 during the movement; and when the air pressure and/or the air flow rise to preset values, determining the position of the corresponding second end as the position of the liquid level.

In some embodiments, the position of the liquid level is used to determine a height of the melt relative to the bottom with an initial height of the movement and a bottom height of the melt.

In some embodiments, the position of the liquid level is used to determine the height of the melt relative to the bottom by determining the distance the second end moves from the position of the liquid level to the bottom of the melt.

In some embodiments, the air inlet conduit 220 is coupled to a drive mechanism that causes the second end to move by driving the air inlet conduit 220.

In some embodiments, the measurement results of the gas measuring device 240 are displayed by display devices disposed outside the inlet pipe 220 and the outlet pipe 230.

In some embodiments, the gas source 210 is further configured to generate a gas flow when the second end moves upward to be separated from the liquid surface after the gas pressure and/or the gas flow rate measured by the gas measuring device 230 rises to a preset value.
