Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to a waste gas treatment device for chemical product production. Background Technology

[0002] Common methods for treating waste gas include adsorption, absorption, catalytic combustion, and thermal combustion. When selecting a purification method, priority should be given to methods that are low-cost, energy-efficient, and do not cause secondary pollution, aiming to turn harmful substances into beneficial ones and fully recover and utilize waste components and heat. In most cases, the petrochemical industry, due to its high exhaust gas concentration, uses methods such as condensation, absorption, and direct combustion; while industries such as paint application and printing, due to their low exhaust gas concentration, use methods such as adsorption and catalytic combustion.

[0003] A search revealed a waste gas treatment device for chemical product production, application number 202021855494.9. The device includes a dust collector with an inlet pipe connected to its left side. A fan is fixedly installed on the inner wall of the inlet pipe. A sealing plate is inserted into the front of the dust collector, and two filter plates are slidably connected to the back of the sealing plate. The outer sides of both filter plates are slidably connected to the inner wall of the dust collector. A lead screw is rotatably connected to the inner wall of the sealing plate, and the lead screw passes through the two filter plates. This utility model, through the arrangement of two filter plates, can filter the waste gas while reducing the amount of dust and particulate matter adhering to the inner wall of the dust collector, thus reducing the difficulty in cleaning the inner wall. By removing the sealing plate, the collected dust and particulate matter can be removed, facilitating cleaning and improving the practicality of the device.

[0004] However, during long-term use, in order to prevent the two filter plates from being clogged by dust and particulate matter, the staff needs to periodically remove the sealing plate and clean the two filter plates. Since this cleaning work needs to be done manually, it will increase the labor intensity of the staff. Utility Model Content

[0005] This utility model provides a chemical product production waste gas treatment device, which aims to solve the problem mentioned in the background art that the filter plates of existing waste gas treatment devices need to be manually removed and cleaned regularly during long-term use, thereby increasing the labor intensity of workers.

[0014] Compared with existing technologies, the chemical product production waste gas treatment device provided in this solution uses a fan to draw waste gas into a through-pipe via the inlet pipe, and finally discharges it from the bottom of the through-pipe. The discharged waste gas is cleaned by the liquid in the shell and undergoes preliminary filtration. The filter cartridge filters the waste gas entering the liquid, collecting dust and particulate matter to prevent them from adhering to the inner wall of the shell. The purification mechanism further purifies the waste gas from both the liquid and the filter cartridge, effectively adsorbing harmful substances. After purification, the waste gas is discharged from the top of the device by opening the exhaust valve. The sealing cap on the pipe allows liquid inside the housing to flow from the outside of the filter cartridge to the inside, and finally discharge from the bottom of the drain pipe. Because the liquid flows into the filter cartridge, it can effectively discharge dust and particles from inside the filter cartridge. Through the use of the cleaning mechanism, the filter cartridge can be automatically cleaned further, effectively removing dust and particles attached to the mesh of the filter cartridge. The cleaned material will be discharged from the drain pipe. The cleaning is convenient and labor-saving. Since the filter cartridge does not need to be removed for cleaning and the device can clean the filter cartridge automatically, the staff can do other things during the cleaning of the filter cartridge, which can greatly reduce the workload of the staff and has a good effect.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a chemical product manufacturing waste gas treatment device, such as... Figure 1-3 As shown, the chemical product production waste gas treatment device includes: a base plate 1, on the top of which multiple support legs are fixedly installed, and the same housing 2 is fixedly installed on the multiple support legs; an annular plate 3 fixedly installed on the inner wall of the bottom of the housing 2, on which a filter cartridge 4 for filtering chemical product production waste gas is rotatably installed; an exhaust pipe 5 fixedly installed at the bottom of the housing 2, on which a sealing cap is threaded; a through pipe 6 fixedly installed on the filter cartridge 4; an air inlet pipe 7 fixedly installed on the housing 2, rotatably connected to the through pipe 6, and a fan 8 fixedly installed on the inner wall of the air inlet pipe 7; a cover 20 fixedly installed on the housing 2, on which a purification mechanism for treating chemical product production waste gas is provided; and a cleaning mechanism assembled on the housing 2 for cleaning the filter cartridge 4.

[0022] In this embodiment, when using the device, firstly, a liquid, such as water, for treating waste gas from chemical product production is added to the housing 2, with the liquid level higher than the filter cartridge 4. Then, the fan 8 is activated, drawing the waste gas into the through-pipe 6 via the inlet pipe 7, and finally discharging it from the bottom of the through-pipe 6. The discharged waste gas is cleaned by the liquid in the housing 2 and undergoes preliminary filtration. Next, the waste gas is filtered by the filter cartridge 4, effectively collecting dust and particulate matter within the filter cartridge 4, preventing large amounts of dust and particulate matter from adhering to the inner wall of the housing 2. The waste gas filtered by the filter cartridge 4 flows out of the liquid surface and then enters the shroud 20, where it is further purified by the purification mechanism, effectively adsorbing harmful substances from the waste gas. After purification, the wastewater will be discharged from the top of the device, resulting in good treatment. After a period of use, a large amount of dust and particulate matter will accumulate in the filter cartridge 4. In order not to affect the use of the device, the filter cartridge 4 needs to be cleaned. During cleaning, the sealing cover on the discharge pipe 5 needs to be opened first. After the sealing cover is opened, the liquid in the housing 2 will flow from the outside of the filter cartridge 4 into the inside of the filter cartridge 4, and finally be discharged from the bottom of the discharge pipe 5. Since the liquid flows into the inside of the filter cartridge 4, the dust and particulate matter inside the filter cartridge 4 can be effectively discharged. After the liquid is discharged, the cleaning mechanism can be activated to automatically clean the filter cartridge 4 in order to further clean it. The cleaned material will also be discharged from the discharge pipe 5. The cleaning is convenient and labor-saving.

[0023] In a further preferred embodiment of the present invention, the purification mechanism includes: a wire mesh 21 fixedly installed on the inner wall of the cover 20, a dehydration layer 22 provided on the top of the wire mesh 21, and an activated carbon layer 23 provided on the top of the dehydration layer 22; and an exhaust pipe 24 fixedly installed on the cover 20.

[0024] In this embodiment, the purification mechanism is used to treat waste gas from chemical product production. After the waste gas has been treated by liquid and filtered by filter cartridge 4, it enters the enclosure 20. The waste gas passes through the wire mesh 21 and comes into contact with the dehydration layer 22 to dehydrate the waste gas, reducing the problem of the activated carbon layer 23 losing activity due to moisture. Then, the dehydrated waste gas passes through the activated carbon layer 23 for filtration. The activated carbon cleans the gas and adsorbs harmful substances in the waste gas. Finally, the purified gas is discharged into the air from the exhaust pipe 24, thereby completing the purpose of purifying the waste gas.

[0025] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a water tank 9 fixedly installed on one side of the housing 2, a high-pressure water pump 10 fixedly installed on the bottom inner wall of the water tank 9, a connecting pipe 11 fixedly installed on the drain end of the high-pressure water pump 10, one end of the connecting pipe 11 extending into the interior of the housing 2; a diversion pipe 12 fixedly installed on one end of the connecting pipe 11, a plurality of high-pressure nozzles 13 fixedly installed on the diversion pipe 12; a motor 14 fixedly installed on the bottom of the housing 2 through a protective shell; a rotating shaft 15 rotatably installed on the housing 2, the bottom end of the rotating shaft 15 being fixedly connected to the output shaft of the motor 14; a first gear 17 fixedly sleeved on the rotating shaft 15; a second gear 18 fixedly sleeved on the filter cartridge 4, the second gear 18 meshing with the first gear 17; and a brush 19 fixedly installed on the inner wall of the housing 2, the bristles of the brush 19 contacting the filter cartridge 4.

[0026] In this embodiment, the cleaning mechanism is used to clean the filter cartridge 4. During cleaning, the sealing cover on the discharge pipe 5 needs to be opened first. After the sealing cover is opened, the liquid inside the housing 2 will flow from the outside of the filter cartridge 4 into the inside of the filter cartridge 4, and finally be discharged from the bottom of the discharge pipe 5. After the liquid is discharged, the high-pressure water pump 10 and the motor 14 are started at the same time. The high-pressure water pump 10 will transport the water in the water tank 9 to the diversion pipe 12 through the connecting pipe 11, and finally spray it out from multiple high-pressure nozzles 13 to perform high-pressure rinsing on the filter cartridge 4, thereby washing off the dust and particles attached to the mesh. The motor 14 will drive the rotating shaft 15 and the first gear 17 to rotate. The first gear 17 will drive the filter cartridge 4 to rotate on the annular plate 3 through the second gear 18. The rotation of the filter cartridge 4 not only allows the multiple high-pressure nozzles 13 to rinse the filter cartridge 4 more thoroughly, but also allows the filter cartridge 4 to be swept by the brush 19, thereby effectively cleaning off the dust and particles attached to the filter cartridge 4. The cleaned material will be discharged from the discharge pipe 5, making cleaning relatively convenient.

[0027] In a further preferred embodiment of the present invention, a pick-up and put-out opening is provided on one side of the cover 20, and a sealing door 16 is provided on the pick-up and put-out opening.

[0028] In this embodiment, by opening the sealing door 16, it is convenient for staff to replace the dehydration layer 22 and the activated carbon layer 23 through the access port.

[0029] In a further preferred embodiment of the present invention, a liquid injection pipe is fixedly installed on the top of the housing 2, and a valve is provided on the liquid injection pipe.

[0030] In this embodiment, by opening the valve, it is convenient for the staff to inject liquid into the housing 2 through the injection pipe. After the injection is completed, the valve needs to be closed to prevent the exhaust gas that has entered the housing 2 from being discharged through the injection pipe.

[0031] In a further preferred embodiment of the present invention, a support frame is fixedly installed on the inner wall of the housing 2, and one side of the support frame is fixedly connected to the diversion pipe 12.

[0032] In this embodiment, the use of the support frame can provide better support for the diversion pipe 12, thereby reducing the supporting pressure of the connecting pipe 11 on the diversion pipe 12.

[0033] In a further preferred embodiment of this utility model, the dehydration layer 22 is a superabsorbent polymer, and a water inlet pipe is fixedly installed on the top of the water tank 9, with a cover provided on the water inlet pipe.

[0034] In this embodiment, the dehydration layer 22, composed of superabsorbent polymer, can effectively absorb moisture in the exhaust gas, reduce the humidity of the exhaust gas, and reduce the problem of the activated carbon layer 23 losing its activity due to moisture.

[0035] In summary, compared with related technologies, this solution, through the use of fan 8, allows the intake pipe 7 to draw exhaust gas into the through pipe 6, and finally discharges it from the bottom of the through pipe 6. The discharged exhaust gas is cleaned by the liquid in the housing 2 and undergoes preliminary filtration. The filter cartridge 4 filters the exhaust gas entering the liquid, collecting dust and particulate matter to prevent them from adhering to the inner wall of the housing 2. The purification mechanism effectively adsorbs harmful substances from the liquid and the exhaust gas treated by the filter cartridge 4. After purification, the exhaust gas is discharged from the top of the device by opening the sealing cap on the discharge pipe 5. The device allows liquid inside the housing 2 to flow from the outside of the filter cartridge 4 into the inside of the filter cartridge 4, and finally discharge from the bottom of the discharge pipe 5. Since the liquid flows into the inside of the filter cartridge 4, it can effectively discharge the dust and particles inside the filter cartridge 4. Through the use of the cleaning mechanism, the filter cartridge 4 can be automatically cleaned further, effectively removing the dust and particles attached to the mesh of the filter cartridge 4. The cleaned material will be discharged from the discharge pipe 5. The cleaning is convenient and labor-saving. Since the filter cartridge 4 does not need to be removed for cleaning and the device can automatically clean the filter cartridge 4, the staff can do other things while the filter cartridge 4 is being cleaned, which can greatly reduce the workload of the staff and has a good effect.
