[0002] Durene and its processed products are widely used in the production of organic chemicals, pharmaceuticals, explosives, synthetic fibers, and other industries. Due to the harm to humans caused by durene during production, reducing the concentration of durene in exhaust gas has become a must-consider issue for durene production units. Existing methods for purifying waste gas generated during durene production mostly use UV photolysis, which can degrade the waste gas into low-molecular compounds, water, and carbon dioxide. However, due to the continuous flow of gas during use, it cannot be guaranteed that the waste gas is completely purified by UV photolysis. Furthermore, as UV photolysis is used, the effectiveness of the photocatalyst decreases. When the decrease reaches a certain level, the purification effect is poor, resulting in a large amount of harmful substances in the discharged waste gas, which pollutes the environment and affects the health of workers.

[0034] Specifically, water can be added to the water tank 2 through the water inlet 52 and discharged through the water outlet 53. For condensation purification, the water in the water tank 2 can cool the gas in the condenser tube 5, thereby achieving a certain condensation effect, thereby purifying the tetramethylbenzene waste gas through condensation; for the waste gas that is directly introduced into the water for purification, water is introduced through the water inlet 52 and discharged through the water outlet 53, which can ensure the flow of water flow, thereby ensuring the purification effect of the waste gas, so that the water flow can better purify the waste gas, reduce the content of harmful substances in the waste gas, and discharge the sewage through the water outlet 53, thereby facilitating the treatment of the sewage; the condenser tube can be drained through the drain pipe 6 The condensed water generated by condensation is discharged to prevent the condensed water from remaining in the condenser tube 5, thereby preventing the condensed water from affecting the condensation, ensuring the condensation effect, and thus ensuring the treatment effect of the exhaust gas of durene. When the condensed water is discharged, the first valve 7 and the second valve 8 can be indirectly opened at this time to allow the condensed water to flow from the condenser tube 5 to between the first valve 7 and the second valve 8, and then the first valve 7 is closed and the second valve 8 is opened to allow the condensed water between the first valve 7 and the second valve 8 to flow out, so that the condensed water can be discharged under a sealed condition, thereby achieving condensation and discharge of the condensed water at the same time, improving the working efficiency of the condensation, thereby improving the purification efficiency of the exhaust gas of durene and ensuring the purification effect of condensation.

[0035] A first connecting port 9 is provided on the top of the water tank 2, a plurality of air inlets 11 are provided on the side of the UV photolysis box 10, a disassembly slot 12 is provided on the top of the purification box 1, and the disassembly slot 12 corresponds to the mounting frame. The mounting frame includes an upper bracket 13 and a lower bracket 14. The purification structure includes a photocatalyst filter plate 16 and a plurality of UV lamp tubes 15 fixed between the upper bracket 13 and the lower bracket 14. The snap-fit ​​fixing structure includes a plurality of card blocks 17 fixed on the upper bracket 13. A plurality of card slots 18 are provided in the UV photolysis box 10, and the card slots 18 correspond to the card blocks 17.

[0036] Specifically, for condensation purification, the exhaust gas is blown out from the condensing pipe 5 into the water tank 2 above the water surface, the exhaust gas is blown out from the first connecting port 9, and then enters the UV photolysis box 10 through the air inlet 11, and the exhaust gas after condensation purification can be photolyzed by the UV photolysis box 10, thereby improving the effect of exhaust gas treatment; for the exhaust gas directly introduced into the water for purification, the exhaust gas is blown out after entering the water for purification, and then blown to above the water surface, and then enters the UV photolysis box 10 through the first connecting port 9 and the air inlet 11, so that the exhaust gas can be purified by the UV photolysis box 10, The UV lamp 15 is energized to emit light, thereby cooperating with the photocatalyst filter plate 16 to improve the photolysis effect of tetramethylbenzene waste gas. When the photocatalyst filter plate 16 needs to be replaced, the mounting frame is pulled upward to separate the card block 17 from the card slot 18, thereby pulling out the upper bracket 13, and the lower bracket 14 can be pulled out synchronously to remove the photocatalyst filter plate 16, thereby facilitating the replacement of the photocatalyst filter plate 16, ensuring the photolysis effect of the photocatalyst filter plate 16, thereby ensuring the treatment effect of the waste gas and improving the treatment efficiency of the waste gas.

[0037] A connecting pipe 19 is fixed between the UV photolysis box 10 and the heating box 56 . The connecting pipe 19 is connected to the UV photolysis box 10 and the heating box 56 . A fan 20 is fixed in the connecting pipe 19 .

[0038] Specifically, the exhaust gas purified by the UV photolysis box 10 enters the connecting pipe 19. By starting the fan 20, the exhaust gas can be blown into the heating box 56 through the fan 20, thereby facilitating the heating and purification of the exhaust gas. Blowing through the fan 20 can ensure the circulation of the exhaust gas and improve work efficiency.

[0039] A driving chamber 22 is provided in the heating box 56, and a motor 21 is fixed in the driving chamber 22. The output end of the motor 21 is fixedly connected to the turntable 23. A plurality of partitions 25 are fixed on the turntable 23. The partitions 25 correspond to the catalytic structure. The catalytic structure includes a plurality of catalyst filter plates 27. A chute 26 is provided between two adjacent partitions 25. The chute 26 corresponds to the catalyst filter plate 27. A plurality of heating tubes 24 are fixed in the box wall of the heating box 56.

[0040] Specifically, the exhaust gas entering the heating box 56 can be heated by the heating pipe 24, and the exhaust gas contacts the catalyst filter plate 27, and an oxidation-reduction reaction occurs quickly in a hot environment, thereby achieving purification of the exhaust gas. In addition, one of the catalyst filter plates 27 can be removed individually. At this time, the other catalyst filter plates 27 can have a better purification effect, which facilitates the replacement of the catalyst filter plate 27 and does not lead to a lower efficiency of the purification work due to the replacement of the catalyst filter plate 27. During purification, the motor 21 is started so that the motor 21 drives the turntable 23 to rotate, thereby driving the multiple partitions 25 and the catalyst filter plates 27 on the turntable 23 to rotate, so that the catalyst filter plates 27 are evenly in contact with the exhaust gas, ensuring that each catalyst filter plate 27 can be fully used, reducing the waste of pressing the catalyst filter plate 27, thereby reducing the purification cost, and the catalyst filter plates 27 are fully in contact with the exhaust gas, which can also ensure the purification effect and further reduce the content of harmful substances in the exhaust gas.

[0041] A mounting block 34 is fixed to the top of the catalyst filter plate 27, and a slot 54 is provided in the mounting block 34. A disassembly rod 31 is slidably fitted on the purification box 1, and an insert block 55 is fixed to the end of the disassembly rod 31. An electromagnet 33 is installed in the insert block 55, and the insert block 55 corresponds to the slot 54. A clamping block 30 is elastically fitted in the mounting block 34, and the clamping block 30 corresponds to the insert block 55 and the catalyst filter plate 27. Grooves 28 are provided on both sides of the slot 54, and the grooves 28 correspond to the clamping block 30. A first spring 29 is fixed between the groove 28 and the clamping block 30.

[0042] When the filter 27 is removed, the filter 27 is automatically released, and the filter 27 is automatically released.

[0043] A connecting pipe is installed between the air outlet pipe 35 and the movable pipe 36. The two ends of the connecting pipe are respectively threadedly matched with the air outlet pipe 35 and the movable pipe 36. The connecting pipe is a hose structure, and the blocking structure corresponds to the connecting pipe.

[0044] Specifically, for the exhaust gas that needs to be circulated and purified, the connecting pipe is connected to the exhaust pipe 35 and the movable pipe 36, so that the exhaust pipe 35 and the movable pipe 36 are connected through the connecting pipe. At this time, the exhaust gas blown out from the exhaust pipe 35 enters the movable pipe 36, and then enters the condenser 5 or the water again, so that the exhaust gas can be purified again, further improving the effect of exhaust gas purification, thereby preventing the exhausted exhaust gas from containing harmful substances and causing air pollution, or the hotter exhaust gas is passed into the condenser 5 for cooling, and the first valve 7 and the second valve 8 at a farther distance are opened for exhaust, so that the exhaust gas that needs to be discharged can be cooled, and the heating energy can be recovered to reduce energy waste.

[0045] The blocking structure includes a blocking block 40 installed in the movable tube 36, and a baffle 49. The blocking block 40 is a conical structure. The baffle 49 is fixedly connected to the movable tube 36. A blocking plate 51 is fixed on the blocking block 40. A plurality of second springs 50 are fixed between the blocking plate 51 and the baffle 49. A second connecting port 37 is opened in the baffle 49, and the second connecting port 37 corresponds to the blocking block 40. A plurality of third connecting ports 38 are opened in the blocking plate 51.

[0046] Specifically, when the connecting pipe is connected, the connecting pipe presses down the blocking plate 51, so that the blocking plate 51 drives the blocking block 40 to move downward, and the second spring 50 is compressed, thereby creating a gap between the blocking block 40 and the second connecting port 37, so that the second connecting port 37 and the third connecting port 38 can be connected, thereby ensuring the circulation of the exhaust gas. When the connecting pipe is not connected, the second spring 50 rebounds and pushes the blocking block 40 to completely block the second connecting port 37, thereby sealing the movable pipe 36 to prevent the exhaust gas from being directly discharged from the movable pipe 36, thereby ensuring the purification effect of the exhaust gas.

[0047] One end of the movable tube 36 is fixed on the relatively outer side of the purification box 1, and the other end of the movable tube 36 is located in the water tank 2. The movable tube 36 is slidingly connected to the movable block 4. The movable block 4 is located between the air intake pipe 3 and the condensation pipe 5. The movable block 4 is fixedly connected to the air intake pipe 3 and the condensation pipe 5. A connecting structure is provided in the movable tube 36. The connecting structure includes a fourth connecting port 39 and a fifth connecting port 41 provided in the movable tube 36. The fourth connecting port 39 is connected to the air intake pipe 3, and the fifth connecting port 41 is connected to the condensation pipe 5. A sixth connecting port 48 is provided in the movable tube 36. The sixth connecting port 48 corresponds to the air intake pipe 3, and the sixth connecting port 48 is located above the fourth connecting port 39.

[0048] Specifically, when condensation purification is performed, the exhaust gas is introduced through the intake pipe 3, the exhaust gas enters the fourth connecting port 39, and then is blown out from the fifth connecting port 41, thereby entering the condensation pipe 5, and the exhaust gas can be condensed and purified through the condensation pipe 5; when the exhaust gas needs to be directly introduced into the water for purification, the movable tube 36 is slid downward so that the movable tube 36 moves downward, so that the sixth connecting port 48 is connected to the intake pipe 3. At this time, the fourth connecting port 39 and the fifth connecting port 41 are both located in the water body, so that the exhaust gas is blown from the intake pipe 3 into the sixth connecting port 48, and then blown into the water through the fourth connecting port 39 and the fifth connecting port 41, and the exhaust gas can be purified by water.

[0049] Working process: When the exhaust gas needs to be purified, the exhaust gas is introduced through the air inlet pipe 3, the exhaust gas enters the fourth connecting port 39, and then is blown out from the fifth connecting port 41, thereby entering the condenser 5, and the exhaust gas can be condensed and purified through the condenser 5, and water is added to the water tank 2 through the water inlet 52, and the water is discharged through the water outlet 53. For condensation purification, the water in the water tank 2 can cool the gas in the condenser 5, thereby achieving a certain condensation effect, thereby purifying the exhaust gas of tetramethylbenzene through condensation, and the condensed water generated by condensation in the condenser 5 is discharged through the drain pipe 6 to prevent the condensed water from remaining in the condenser 5, thereby preventing the condensed water from affecting the condensation, ensuring the condensation effect, and thus ensuring the exhaust gas of tetramethylbenzene. The treatment effect is achieved when the condensed water is discharged. At this time, the first valve 7 and the second valve 8 can be indirectly opened to allow the condensed water to flow from the condenser pipe 5 to between the first valve 7 and the second valve 8. Then, the first valve 7 is closed and the second valve 8 is opened to allow the condensed water between the first valve 7 and the second valve 8 to flow out. Thus, the condensed water can be discharged under a sealed condition, thereby achieving condensation and discharge of condensed water at the same time. Then, the exhaust gas is blown out through the condenser pipe 5 into the water tank 2 above the water surface, and the exhaust gas is blown out from the first connecting port 9 and then enters the UV photolysis box 10 through the air inlet 11. The condensed and purified exhaust gas can be photolyzed by the UV photolysis box 10, thereby improving the effect of exhaust gas treatment. The UV lamp 15 is energized so that the UV The lamp tube 15 emits light, thereby cooperating with the photocatalyst filter plate 16 to improve the photolysis effect of tetramethylbenzene exhaust gas. When the photocatalyst filter plate 16 needs to be replaced, the mounting frame is pulled upward to separate the card block 17 from the card slot 18, thereby pulling out the upper bracket 13, so that the lower bracket 14 can be pulled out synchronously, and the photocatalyst filter plate 16 can be removed, thereby facilitating the replacement of the photocatalyst filter plate 16. Then, the exhaust gas purified by the UV photolysis box 10 enters the connecting pipe 19, and the fan 20 is started, and the exhaust gas can be blown into the heating box 56 through the fan 20, thereby facilitating the heating and purification of the exhaust gas. The exhaust gas entering the heating box 56 can be heated by the heating pipe 24, and the exhaust gas is connected to the catalyst filter plate 27. When the catalyst filter plate 27 needs to be disassembled and replaced, the disassembly rod 31 is slid downward so that the disassembly rod 31 drives the plug 55 to move downward, thereby making the plug 55 enter the slot 54, and the electromagnet 33 is energized so that the plug 55 is adsorbed and fixed to the mounting block 34, and then the disassembly rod 31 is pulled upward so that the disassembly rod 31 drives the mounting block 34 to move upward, thereby making the mounting block 34 be pulled out, and the catalyst filter plate 27 can be pulled out.This allows the catalyst filter plate 27 to be removed and replaced. During the removal process, the first spring 29 always pushes the clamping block 30 to contact the mounting block 34 or the catalyst filter plate 27. The clamping block 30 squeezes the catalyst filter plate 27, thereby preventing air leakage from the gap between the catalyst filter plate 27 and the heating box 56 to a certain extent, ensuring a good sealing effect.

[0050] For the waste gas that is directly introduced into the water for purification, slide the movable tube 36 downward so that the movable tube 36 moves downward, thereby connecting the sixth connecting port 48 with the air inlet pipe 3. At this time, the fourth connecting port 39 and the fifth connecting port 41 are both located in the water body, so that the waste gas is blown from the air inlet pipe 3 into the sixth connecting port 48, and then blown into the water through the fourth connecting port 39 and the fifth connecting port 41. At this time, water is introduced through the water inlet 52 and discharged through the water outlet 53, which can ensure the flow of water and thus ensure the purification effect of the waste gas. The water flow can better purify the waste gas and reduce the content of harmful substances in the waste gas. The sewage can also be discharged through the water outlet 53, which facilitates the treatment of the sewage. The waste gas is blown out of the water and then enters the UV photolysis box 10 and the heating box 56 for further treatment, so that the waste gas can be better purified.

[0051] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
