Technical Field

The invention relates to a method and a device for degrading and deodorizing by using ozone.

Background

Ozone has strong oxidizing power, can rapidly and thoroughly decompose various peculiar smells in water or air, only needs electricity, clean air or pure oxygen in a generating mode, has no material consumption requirement and no secondary pollution, and therefore, a system or equipment for deodorizing by using ozone is developed in various fields at present. For example, the industry of decomposing nutrients from the meat and bones of livestock and poultry has a need for ozone deodorization technology to solve the problem of tail gas emission.

However, since there is no method for effectively monitoring odor index in the current deodorization method for discharging various organic and inorganic waste gases, although the objective of deodorization is achieved by degrading and oxidizing various odor functional groups with ozone, there is no scheme for effectively detecting or monitoring odor. Most monitoring gas analyzers can only detect the concentration of specific organic gases, but cannot detect the concentration of waste gas mixed with various organic exhaust gases, and such instruments are expensive, cannot resist long-term use in a severe environment for 24 hours, and may be easily misaligned. Therefore, in practical application, problems such as difficult maintenance and failure to perform continuous accurate application control are caused.

Detailed Description

Exemplary embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, but the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, the size and thickness of regions, regions and layers may not be drawn to scale for clarity. For ease of understanding, like elements in the following description will be described with like reference numerals.

FIG. 1A is a schematic block diagram of an apparatus for deodorization by ozone degradation according to a first embodiment of the present invention.

Referring to fig. 1A, the apparatus 100 for deodorizing with ozone degradation according to the first embodiment is used to deodorize an exhaust/waste water environment 102, wherein the exhaust/waste water environment 102 may be a process (plant) pipeline, a garbage dump (area) or a treatment tank, but the invention is not limited thereto. The apparatus 100 for deodorization by ozone degradation at least comprises an ozone generation monitoring device 104 and an ozone off-gas monitoring device 106. Ozone production monitoring device 104 is used to produce ozone and monitor it. In one embodiment, ozone generation monitoring device 104 includes an ozone generating device 110, a power controller 112, and a process controller 114. The ozone generating device 110 can supply ozone to the waste gas/water environment 102, and the power controller 112 is coupled to the ozone generating device 110 for controlling the ozone generating amount of the ozone generating device 110. The process controller 114 is coupled to the power controller 112 and outputs a control command signal to the power controller 112, wherein the control command signal can be a voltage, a current or a digital pulse signal. The process controller 114 may be, for example, a program logic controller or an IO controller of a PC-base. The ozone generation amount of the ozone generating device 110 is controlled as described in detail below.

In fig. 1A, ozone off-gas monitoring device 106 is used to collect sample gas, and so-called sample gas is off-gas from exhaust/wastewater environment 102. The "off-gas" in the embodiment refers to gas at a position of about several meters forward (or outward) of the exhaust gas discharge port. If the flue gas/waste water environment 102 is a pipeline (e.g., a stack) from which the process is ultimately discharged to the atmosphere, the tail gas is about several meters forward of the stack discharge, and this position can be adjusted according to the actual environment. The ozone tail gas monitoring device 106 comprises an ozone analyzer 108, a first temperature reduction and dehumidification device 107a and a first dust removal and particle removal device 107b, wherein the ozone analyzer 108 receives ozone from the ozone generation device 110 and tail gas from the waste gas/wastewater environment 102 as sampling gas for analysis, and feeds back different ozone concentration signals to the process controller 114 in the ozone generation monitoring device 104, so that the process controller 114 controls the power controller 112 according to the different ozone concentration signals. The ozone analyzer 108 is, for example, an Ultraviolet (UV) type ozone analyzer or an electrochemical type ozone analyzer. Furthermore, the ozone analyzer 108 in this embodiment is a multi-channel ozone analyzer that can feed back the different ozone concentration signals to the process controller 114 synchronously or asynchronously.

The process controller 114 makes a determination based on the ozone concentration signal of the sampled gas; if the ozone concentration signal of the sampling gas is a preset target value, the current stage is deodorized, and the ozone concentration of the sampling gas needs to be continuously monitored; if the target value is lower than the target value, the process controller 114 outputs a control command signal to the power controller 112 to increase the ozone generation amount of the ozone generating device 110 by high power; if the target value is higher, the process controller 114 outputs another control command signal to the power controller 112 to reduce the amount of ozone generated by the low power. In other words, the power controller 112 is a device capable of outputting different powers to vary the amount of ozone generated, such as a controllable electric power device or a dual voltage power supply.

The first temperature reduction and dehumidification device 107a in the ozone tail gas monitoring device 106 is used for reducing the temperature and dehumidifying the sampling gas, and the first dust removal and particle removal device 107b is disposed behind the first temperature reduction and dehumidification device 107a, but the invention is not limited thereto; in another embodiment, the number of the first dust-removing and particle-removing devices 107b can be multiple; that is, the plurality of first dust and particle removing devices 107b may be respectively disposed at the front end of the first temperature-reducing and dehumidifying device 107a, or a set of first dust and particle removing devices 107b (not shown) may be disposed in front of the first temperature-reducing and dehumidifying device 107a for removing micro-dust and particles in the sampling gas. Such a design is for a sampling gas with a large amount of fine dust, high temperature or high humidity, and facilitates the analysis by the ozone analyzer 108. In one embodiment, the sampled gas passes through the first temperature reduction and dehumidification device 107a and then enters the first dust and particle removal device 107b, but the invention is not limited thereto. In another embodiment, the sampled gas passes through the first dust and particle removing device 107b and then enters the first temperature and humidity reducing and dehumidifying device 107 a. The number of the first cooling and dehumidifying devices 107a can also be one or more; that is, there may be two first temperature-reducing and dehumidifying devices 107a and one first dust-removing and particle-removing device 107b disposed therebetween in the ozone off-gas monitoring device 106; or two first dust and particle removing devices 107b and a first temperature-reducing and dehumidifying device 107a arranged therebetween, and so on. In addition, the first dust and particle removing device 107b may further comprise a back washing device (not shown) for back washing the first dust and particle removing device 107b during the idle period of the ozone tail gas monitoring device 106, so as to increase the service life thereof.

Referring to fig. 1B, the difference between the above-mentioned fig. 1A and fig. 1B is that the waste gas/wastewater environment for deodorization is a treatment tank 202, and thus the treatment tank 202, the ozone generation monitoring device 104 and the ozone off-gas monitoring device 106 can be disposed in a machine 204.

Fig. 2 is a block diagram of an apparatus for degradation and deodorization by ozone according to a second embodiment of the present invention, wherein the same reference numerals as in the first embodiment are used to represent the same or similar components, and the description of the same components can refer to the first embodiment, which is not repeated herein.

Referring to fig. 2, the difference between the apparatus 200 for degrading and deodorizing with ozone of the second embodiment and the first embodiment is that the ozone analyzer 108 is independently installed, and the ozone off-gas pre-sampling treatment apparatus 107 including the first temperature reduction and dehumidification apparatus 107a and the first dust and particle removal apparatus 107b is retained to collect the sampling gas. Such a design enables the ozone analyzer 108 to be located close to the ozone generation monitoring device 104 or close to the exhaust gas according to different requirements.

Fig. 3 is a block diagram of an apparatus for degradation and deodorization by ozone according to a third embodiment of the present invention, wherein the same reference numerals as in the second embodiment are used to represent the same or similar components, and the description of the same components can refer to the second embodiment, which is not repeated herein.

Referring to fig. 3, the difference between the apparatus 300 for degrading and deodorizing with ozone of the third embodiment and the second embodiment is the design of the ozone off-gas sampling pretreatment apparatus 307. In this embodiment, the ozone tail gas sampling pre-processing device 307 includes a first temperature reduction and dehumidification device 107a and a first dust and particle removal device 107b, and further includes a second temperature reduction and dehumidification device 307a and a second dust and particle removal device 307b disposed behind the second temperature reduction and dehumidification device 307a, wherein the second temperature reduction and dehumidification device 307a is used for cooling and dehumidifying the ambient gas, and the second dust and particle removal device 307b is used for removing micro-dust and particles in the ambient gas. The term "ambient gas" as used herein refers to atmospheric gases such as ventilation air where ozone is placed, outdoor air, or alternatively ducted clean air. In this case, the ozone analyzer 108 can also receive the environmental gas from the ozone off-gas sampling pretreatment device 307 for analysis, and feed back the ozone concentration signal of the environmental gas to the process controller 114 as a background value.

FIG. 4 is a block diagram of an apparatus for degradation and deodorization by ozone according to a fourth embodiment of the present invention, wherein the same reference numerals as in the third embodiment are used to designate the same or similar components, and the description of the same components can refer to the third embodiment, which is not repeated herein.

Referring to fig. 4, the difference between the apparatus 400 for degrading and deodorizing with ozone of the fourth embodiment and the third embodiment is that the ozone off-gas sampling pretreatment apparatus 107 does not have the second temperature reduction and dehumidification device 307a and the second dust and particle removal device 307b, and the ozone analyzer 408 includes a first ozone analyzer 408a and a second ozone analyzer 408 b. First ozone analyzer 408a receives ozone from ozone generating device 110 and feeds back a first ozone concentration signal to process controller 114. The second ozone analyzer 408b receives the sampled gas from the ozone off-gas sampling pretreatment device 107 and feeds back a second ozone concentration signal to the process controller 114, wherein the first ozone concentration signal is greater than the second ozone concentration signal. In other words, first ozone analyzer 408a is a high concentration ozone analyzer, and second ozone analyzer 408b is a low concentration ozone analyzer. The process controller 114 also makes the determination based on the second ozone concentration signal of the sampled gas; if the second ozone concentration signal is a preset target value, the deodorization is finished at the stage, and the ozone concentration of the sampling gas needs to be continuously monitored; if the target value is lower than the target value, the process controller 114 outputs a control voltage, current or digital pulse to the power controller 112 to increase the ozone generation amount of the ozone generating device 110 by high power; if the target value is higher, the process controller 114 outputs another control voltage, current or digital pulse to the power controller 112 to reduce the amount of ozone generated by the low power. The first ozone concentration signal can be used to determine whether the ozone generation amount of the ozone generating device 110 meets the requirement, for example, if the first ozone concentration signal is lower than a predetermined value, the process controller 114 controls the power controller 112 to supply higher power to the ozone generating device 110 to increase the ozone generation amount; and vice versa.

FIG. 5 is a block diagram of an apparatus for degrading and deodorizing with ozone according to a fifth embodiment of the present invention, wherein the same reference numerals as in the third embodiment are used to designate the same or similar components, and the description of the same components can refer to the third embodiment, which is not repeated herein.

Referring to fig. 5, the difference between the apparatus 500 for deodorization by ozone degradation of the fifth embodiment and the third embodiment is that the ozone analyzer 508 includes a first ozone analyzer 508a and a second ozone analyzer 508 b. First ozone analyzer 508a receives ozone from ozone generating device 110 and feeds back a first ozone concentration signal to process controller 114. The second ozone analyzer 508b receives the sampled gas from the ozone off-gas sampling pretreatment device 307 and feeds back a second ozone concentration signal to the process controller 114, wherein the first ozone concentration signal is greater than the second ozone concentration signal. For feedback of the process controller 114 and the first and second ozone concentration signals, reference is made to the fourth embodiment, which is not described herein again. In this embodiment, the second ozone analyzer 508b can also receive the environmental gas from the ozone off-gas sampling pretreatment device 307 for analysis, and feed back the ozone concentration signal of the environmental gas to the process controller 114. In addition, the apparatus 500 for deodorization by ozone degradation may further comprise an exhaust pump 502 connected to the second ozone analyzer 508b for sampling and exhausting the sampled gas under a negative pressure pipeline. Such a design may also be applied to other embodiments, such as an exhaust pump 502 coupled to the ozone analyzer 108 of FIG. 1A for exhausting sample gas and analyzed ozone (not shown).

Fig. 6 is a block diagram of an apparatus for degradation and deodorization by ozone according to a sixth embodiment of the present invention, wherein the same reference numerals as in the fifth embodiment are used to represent the same or similar elements, and the description of the same elements can refer to the fifth embodiment, which is not repeated herein.

Referring to fig. 6, the difference between the apparatus 600 for deodorization by ozone degradation of the sixth embodiment and the fifth embodiment is that a wireless communication transmitter 602 and a receiver 603 are added, so that a signal can be transmitted to the process controller 114 through the receiver 603, and the exhaust pump 502 is omitted. Such a design is suitable for the case where the ozone generation monitoring device 104 is far away from the ozone analyzer 508, and the first ozone analyzer 508a and the second ozone analyzer 508b of the ozone analyzer 508 are respectively disposed in different areas, such as the first ozone analyzer 508a is close to the ozone generation monitoring device 104, and the second ozone analyzer 508b is close to the ozone tail gas sampling pretreatment device 307. Therefore, the wireless communicator 602 and the receiver 603 are utilized to wirelessly transmit the second ozone concentration signal of the second ozone analyzer 508b to the process controller 114. Of course, such wireless transmission may be applied to other embodiments.

FIG. 7 is a diagram showing a process of deodorizing by ozone degradation according to a seventh embodiment of the present invention.

Referring to fig. 7, the method for degradation and deodorization with ozone according to the seventh embodiment can be performed by using the apparatus according to the above embodiments, but the present invention is not limited thereto. First, step 700 is performed to supply ozone to the exhaust/wastewater environment using an ozone generation monitoring device. The ozone generation monitoring device comprises an ozone generating device, a power controller coupled with the ozone generating device and a process controller coupled with the power controller, wherein the power controller is used for controlling the ozone generating amount of the ozone generating device, and the process controller is used for outputting a control command signal to the power controller, wherein the control command signal can be voltage, current or a digital pulse signal. In addition, in step 700, the ozone generated by the ozone generating device may be transmitted to the ozone analyzer for analysis, and the ozone concentration signal of the ozone may be fed back to the process controller synchronously or asynchronously.

Thereafter, step 702 is performed to send the sampled gas, which is the exhaust from the exhaust/wastewater environment, to an ozone analyzer for analysis to feed back an ozone concentration signal to a process controller of an ozone generation monitoring device. In one embodiment, the ozone analyzer is, for example, a multi-channel ozone analyzer. In another embodiment, the ozone analyzer comprises a plurality of ozone analyzers for analyzing the sample gas and the ozone generated by the ozone generating device respectively. Before step 702, the temperature of the sampling gas may be lowered and the sampling gas may be dehumidified, and the dust particles and particles in the sampling gas may be removed. In addition, the method for feeding back the ozone concentration signal to the process controller comprises wired or wireless transmission. In step 702, the ambient gas may also be sent to the ozone analyzer for analysis, and an ozone concentration signal of the ambient gas is synchronously fed back to the process controller as a background value.

The process controller makes a determination based on the ozone concentration signal. That is, in step 704, if the ozone concentration signal is a target value, the ozone concentration of the sample gas (i.e., exhaust gas) is continuously monitored. Otherwise, if the ozone concentration signal is not the target value, the next stage of determination is performed, and if the ozone concentration signal is lower than the target value (step 706), the process controller outputs a control command signal to the power controller to increase the amount of ozone generated in step 708. Conversely, if the ozone concentration signal is higher than the target value (step 710), then the process controller outputs another control command signal to the power controller to reduce the amount of ozone generated in step 712, and returns to step 704 to repeat the control confirmation.

In summary, the present invention utilizes the ozone analyzer to detect the tail gas of the waste gas/wastewater environment and feed back the tail gas to the process controller for controlling the ozone generating device in real time, so as to deodorize the waste gas/wastewater environment and simultaneously adjust the ozone generating amount in real time, so that the ozone discharge amount is stably maintained at the target value, thereby achieving the dual effects of meeting the environmental protection and deodorization, effectively improving the environmental protection and electricity utilization benefits, and avoiding the safety problem caused by excessive ozone generation.

Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto. The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
