Technical Field

The invention relates to a solid-liquid separator with unpowered cyclone claws and a separation method, belonging to the technical field of rain sewage treatment and environmental protection.

Background

The urban rain season rainwater runoff, in particular to the surface runoff formed in the early stage of heavy rain or heavy rain and the combined overflow sewage have the characteristics of large instantaneous water amount, high solid suspended matter content, large pollution load and the like. If the waste water is directly discharged into urban water without treatment, serious pollution is caused to the waste water. The method has the advantages of simple structure, small occupied area, long service life, convenient maintenance and management and the like, has better effect of removing larger suspended particles, and is being applied more and more. However, almost all unpowered cyclones currently in use have a common problem: the removal of small-sized particles is not ideal in the case of large inflows. The research and application in the aspect of China are few, and no mature technology and equipment belong to the China. With the gradual importance of initial rainwater runoff and combined overflow sewage pollution in China and the large-scale development and implementation of sponge cities at the present stage, the solid-liquid cyclone separation technology will become a focus area.

Meanwhile, in the field of urban and rural sewage treatment, sewage desanding is always a common problem, for example, the desanding effect is poor, which can cause the aggravation of the abrasion of a series of subsequent equipment on the one hand, and on the other hand, can also cause the deposition of a large amount of sand in the process units such as the primary sedimentation tank, the aeration tank, the sludge storage tank and the sludge digestion tank, even block pipelines, and seriously affect the production. Due to the influence of factors such as large-scale urban construction and imperfect pipe networks, the sand content of domestic sewage is generally higher, and the importance of sewage sand removal is more highlighted. The common sewage sand removing method uses various grit chambers, such as a gravity grit chamber, an aeration grit chamber, an inclined plate or inclined tube grit chamber, a rotational flow grit chamber and the like, and research results show that the grit chambers can only effectively remove sand grains with the size of more than 0.2mm, the occupied area is large, and a large amount of energy is consumed.

Therefore, how to effectively remove smaller and lighter particles from various rain water on a large scale has been a problem to be solved. The research finds that: 1. the removal of particles with a size of less than 0.25mm is the key to sewage treatment, because in runoff and other sewage, the heavy metal content of the small particles accounts for more than 80% of the total load; 2. more than half of the deposit size is greater than 0.3mm but only accounts for less than 15% of the total phosphorus and nitrogen; 3. half of the heavy metal adheres to particles between 0.06 and 0.20mm in size. Effective removal of fine particulate matter from water is important as smaller particles are found to cause more environmental pollution.

The main reason that various solid-liquid cyclone separators cannot effectively remove light and small suspended particles at present is that the suspended particles always run together with the main flow entering water in the separators. Based on the above, the invention provides an unpowered cyclone claw solid-liquid separator and a separation method, which utilize the cyclone generated in parallel grooves when main flow flows through the groove openings above the parallel groove array to grab suspended particles in inflow from rapid inflow to a relatively quiet groove bottom so as to reduce the interference of the main flow and shorten the distance between the suspended particles and the groove bottom, thereby promoting the sedimentation of the suspended particles (especially light and small particles which are easy to be interfered).

Detailed Description

The following description of the preferred embodiments of the present invention with reference to the accompanying drawings will more clearly and completely illustrate the technical solutions of the present invention.

As shown in fig. 1-2, an unpowered cyclone claw solid-liquid separator comprises a housing 1 and a water inlet and outlet device on the housing, wherein the housing 1 is of an upper-cylinder lower-cone structure, a cyclone claw generator 3 is arranged in an upper cylinder body, a lower cone (the inclination of which is not less than 45 degrees) is a precipitate storage cavity 18, the cyclone claw generator 3 comprises a plurality of cone parallel groove arrays 11 stacked together, the cone parallel groove arrays 11 comprise a housing of the upper-cylinder lower-cone structure, a circular opening 23 is arranged at the top of the housing, a plurality of parallel groove walls 15 arranged in parallel are arranged on a conical surface (the inclination of which is not less than 45 degrees) of the housing, and the parallel groove walls 15 extend along the upper conical surface of the housing. The bottom of the housing 1 is provided with a plurality of supports 2 for supporting the swirling claw generator 3 to ensure that the caught suspended particles smoothly fall into the sediment storage chamber 18.

The rotational flow claw solid-liquid separator adopts the basic principle that the rotational flow generated in the parallel grooves when the main flow flows through the notches above the parallel groove arrays takes away suspended particles in the main flow, so that the interference of main flow disturbance force on the captured suspended particles is greatly reduced. As the inflow rate increases, although the residence time of the fluid in the separator is shortened, the probability of entrained particles is relatively increased since the strength of the swirl generated by the main flow will increase. The comparative experiment result shows that the particle removing efficiency of the cyclone claw solid-liquid separator is much less influenced by the inflow flow rate than that of other similar equipment, and the cyclone claw solid-liquid separator still has the advantage of obviously removing light and small suspended particles under the condition of large inflow rate.

In this embodiment, the water inlet and outlet device includes outlet pipe 10, inlet tube 9 that set up side by side, and inlet tube 9 passes through right angle return bend 7 and perpendicular water pipe 8 intercommunication, and perpendicular water pipe 8 is opened at the co-altitude not has the round hole, and the distribution and the aperture of round hole are decided by concrete application, and the round hole through the axial arrangement communicates each cone and moves the treatment chamber 28 between the groove matrix 11. The water outlet pipe 10 is communicated with the top of the upper cylinder body, and a partition plate 22 for separating inlet water from outlet water is arranged on the shell 1.

Furthermore, the side edge of the cone parallel groove array 11 is provided with a water inlet opening 29, so that the vertical water pipe 8 can extend to the bottom of the rotational flow claw generator 3 along the water inlet opening 29, and the bottom of the vertical water pipe 8 can be made into a cone shape, so that the opening at the bottom of the water pipe is smaller than the pipe diameter of the vertical water pipe. As shown in fig. 9, a water inlet baffle 14 may be provided at the bottom of the vertical water pipe (i.e. below the water inlet openings of the bottom most cone parallel array) in order to prevent the inflow of water into the sediment storage chamber.

After entering water from the water inlet pipe and entering the cyclone claw solid-liquid separator, the water flows into the vertical water pipe through the right-angle bent pipe, because the holes are distributed on the vertical water pipe at different heights, and the bottom opening of the vertical pipe can be connected with the tail pipe with the diameter gradually reduced according to the condition, the flow of the water is uniformly distributed in different water depths after the water flows out of the vertical water pipe, in other words, the water quantity flowing into the cones on different layers and the groove arrays is basically the same, and the inflow is efficiently divided.

As shown in fig. 3-4, for the application situation that large-sized suspended substances in the water need to be removed first, a water inlet pool 24 and a water outlet pool 25 need to be added to the housing 1, the water inlet pool 24 and the water outlet pool 25 are arranged in parallel on the outer cylindrical surface of the housing 1, the water inlet pool 24 is communicated with each treatment cavity 28 sequentially through a filter screen 13 and a honeycomb panel 12, a right-angle elbow 7 and a vertical water pipe 8 are arranged in the water inlet pool 24, and the water outlet pipe 10 is communicated with each treatment cavity 28 through the water outlet pool 25.

The filter screen prevents large-size suspended matters in water from entering each treatment cavity 28, inflow of the filter screen is further rectified through the honeycomb screen plate, water flow is forced to uniformly move along the horizontal direction, accordingly, rotational flow can be generated in the parallel grooves more effectively, the generated rotational flow is more regular, and efficiency of capturing suspended particles is improved.

Furthermore, the height of the bottom of the water inlet pool is not higher than that of the bottom of the rotational flow claw generator, and the size of the water outlet pool is not larger than that of the water inlet pool; the width and length of the filter screen should cover the whole water inlet channel, and the mesh aperture of the filter screen should be determined by specific application and should not be smaller than 3mm generally; the total area of the openings of the honeycomb plate is at least 20% larger than the section of the water inlet pipe, the width and the length of the openings of the honeycomb plate are capable of covering the whole water inlet channel, the thickness of the openings of the honeycomb plate is not less than 10cm, and the shape of the openings of the single honeycomb plate is not limited.

Because the cone parallel groove array is composed of a cone with a smooth surface and a plurality of parallel groove walls which are arranged in parallel, the structure of the cone parallel groove array is slightly different according to different installation positions, but the working principle of the cone parallel groove array is the same, and the sizes of the openings at the bottoms of the cones of all the cone parallel groove arrays are the same. As shown in fig. 6-8, the circular opening of the top cone parallel groove array is larger than that of the second layer, the circular opening of the second cone parallel groove array is larger than that of the third layer (the height of the circular opening is higher than that of the first layer but lower than that of the third cone parallel groove array), the circular openings of the third layer to the bottom cone parallel groove array are consistent in size, inner cylinders are arranged at the circular openings of the third layer to the bottom cone parallel groove array, and adjacent inner cylinders are sequentially butted to form an inner channel 19 communicated with the sediment storage cavity. That is, from the third layer, the structure of the parallel groove array of each layer of cones is basically the same.

As shown in fig. 13, the sediment storage chamber is substantially isolated from the main flow, and no other passage is available except for a small amount of water that can enter the sediment storage chamber along the particle transfer passage, so that the collected sediment will remain in the sediment storage chamber until it is removed, thereby preventing secondary pollution from occurring. In addition, a bypass baffle 4 may be installed at the bottom of the housing to prevent any possible bypass flow in the sediment storage chamber.

Furthermore, the parallel slot walls can have different arrangement modes according to different conditions: it may run along the cone radial line as shown in fig. 6-8, or at an angle to the cone radial line as shown in fig. 10; the parallel groove walls can be arranged perpendicular to the conical surface of the shell and can also be inclined to the conical surface of the shell at a small angle; the height of the parallel groove wall is not less than the net distance between two parallel groove walls, and the net distance between the parallel groove walls is different from top to bottom, so the height of the same parallel groove wall can be different from top to bottom. In some special applications, the parallel groove wall can be made to be zero height, i.e. the cone surface no longer has parallel grooves, which will evolve into a cone slope.

As shown in fig. 11, the parallel groove walls may have different shapes and the cross section may be: a-b, flat top and flat bottom, c, flat bottom and triangular top, d, flat top and bottom right lower corner are recessed, e, top is triangular and bottom right lower corner is recessed.

As shown in fig. 5, the tail end of the parallel groove wall 15 is connected with a particle conveying channel 16, the particle conveying channel 16 extends vertically along the outer cylindrical surface of the shell, and the particle conveying channels 16 on the adjacent parallel cone groove arrays 11 are butted up and down to form a settling channel communicated with a sediment storage cavity 18, so that solid particles captured in each layer are conveyed into the sediment storage cavity without any interference of water flow.

When the device is operated, firstly the main stream of the inlet water is shunted, then the suspended particles in the inlet flow are caught to the relatively quiet tank bottom from the rapid inlet flow by utilizing the rotational flow generated in the parallel tank when the shunted flow flows through the notches above the cone parallel tank array, finally the sediment falling on the parallel tank bottom or the parallel tank wall slides into the particle conveying channel along the steep tank bottom inclined plane and falls into the sediment storage cavity separated from the main stream along the particle conveying channel, and the inlet water flows away from the water outlet pipe after surrounding the cone parallel tank array for one circle.

As shown in fig. 12, the particle transport passage 16 and the parallel groove walls 15 are in a one-to-one correspondence, the side wall of the particle transport passage 16 is provided with a passage inlet 21, the tail of the parallel groove is divided into two parts, wherein one half of the groove bottom is communicated with the passage inlet 21, and the other half of the groove bottom is provided with a rib 30 for guiding the particles to the passage inlet 21.

That is, in order to reduce the probability of water flowing into the particle transport passage, the particle transport passage is only connected with the tail of the half groove of the parallel groove, the particles sliding down from the other half of the parallel groove are guided into the particle transport passage by the baffle plate, and the height of the inlet of the passage is lower than that of the wall of the parallel groove.

Furthermore, the top of the particle transport channel 16 of the uppermost cone parallel groove array is provided with a circular baffle 17, which aims to prevent water from flowing into the particle transport channel and force the inlet water to run around the uppermost cone parallel groove array.

Furthermore, the bottom of the sediment storage cavity 18 is provided with a sampling port 6 and a sampling pipe 5 which are used for sampling during the experiment and are not an underflow drain outlet. But also can be used for discharging the collected precipitate in practical application. Another method of cleaning the collected sediment is to open the top of the cyclone claw solid-liquid separator and suck the bottom sediment through the inner channel 19. The equipment does not need special maintenance management in normal times.

When treating some viscous sewage with the cyclone claw solid-liquid separator, some deposits may be attached in the parallel grooves, and frequent cleaning is required in order to maintain the working efficiency of the cyclone claw solid-liquid separator, thereby providing an automatic cleaning apparatus. As shown in fig. 14, the automatic cleaning device includes a spray pipe 26 communicated with a high-pressure water source, a pipeline for inserting the spray pipe 26 is opened on the upper side of the parallel groove wall 15, a plurality of cleaning openings 27 communicated with the pipeline are opened on the parallel groove wall 15, and a spray opening corresponding to the cleaning opening 27 is opened on the spray pipe 26.

Further, all of the spray pipes 26 inserted into the pipe are connected at their upper ends to each other and to a high-pressure water source, and the lower ends of the spray pipes 26 are closed. When cleaning is required, the connected high pressure water is opened and the high pressure water is ejected from the cleaning ports 27 on the parallel tank walls 15 to remove the accumulated material in the tank.

As shown in fig. 15, when the incoming water is circulated between the parallel arrays of cones, due to the kinetic power and direction of travel of the water stream, a swirling flow 20 is created in the parallel channels as it passes through the slots above the parallel channels at 90 degrees (or nearly 90 degrees) to the direction of extension of the parallel channels. Based on this, the present invention promotes the precipitation of suspended particles from several aspects: firstly, the split inflow is limited in a treatment cavity between the cone parallel groove arrays, so that the probability of capturing suspended particles by rotational flow can be increased to a great extent; secondly, the suspended particles in the main stream can be brought to a relatively quiet tank bottom part from the rapid main stream to reduce the interference of the main stream, and the distance between the suspended particles and the tank bottom is shortened; finally, the contact area of the inclined plates which can promote the sedimentation of the particles is greatly increased, and the sediments falling on the bottom of the parallel groove or the parallel groove walls slide to the particle conveying channel at the tail end along the steep inclined surface of the bottom of the groove, because each layer of particle conveying channel is connected to form an almost closed long channel, and the entering sediments are always conveyed to the sediment storage cavity at the bottom.

The cyclone claw solid-liquid separation equipment provided by the invention can be used as a high-efficiency solid-liquid separator or a sedimentation tank for treating sewage such as rainwater runoff, combined overflow sewage, urban and rural sewage, mining and oil extraction and the like, has no special requirements on a use area, and can be installed under the ground or on the ground.

When in use, the rainwater and sewage supply pipe is connected with the water inlet pipe, and the water outlet pipe is connected with the water discharge pipe to run. When the cyclone claw solid-liquid separator is installed under the ground, a hole needs to be formed in the ground right above the central hole of the cyclone claw generator so as to suck and remove sediments. For the cyclone claw solid-liquid separator with the water inlet and outlet pool, the ground right above the water inlet pool is also provided with holes for absorbing large-size substances.

Under the condition that the diameter of the rotational flow claw generator is determined, the required stacking number of the cone parallel groove arrays can be determined according to the requirements of treatment flow and efficiency. Because the cyclone claw generator is formed by vertically stacking a plurality of cone parallel groove arrays, the processing capacity of the cyclone claw solid-liquid separator can be improved by increasing the stacking number of the cone parallel groove arrays without increasing the diameter of the separator, thereby obtaining higher processing efficiency in more economic floor area.

The above embodiments relate to a design framework based on a cylindrical device, which can be modified to a similar device of an elliptical (as shown in fig. 16) or other polygonal configuration, of course, under the same principles.

Therefore, the above detailed description merely describes preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the spirit and scope of the present invention, it should be understood that various changes, substitutions and alterations can be made herein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
