Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical waste gas purification technology, and more specifically, to a multi-stage chemical waste gas purification device. Background Technology
[0002] Chemical waste gas refers to a mixture of gaseous pollutants generated and emitted into the atmosphere during chemical production processes (such as raw material processing, chemical reactions, product separation, storage and transportation). These waste gases have complex compositions and usually contain a variety of harmful substances. If chemical waste gas is directly emitted, it will cause serious harm to the environment and human health. Therefore, it is necessary to remove the pollutants through physical, chemical or biological methods so that the chemical waste gas can meet the emission standards before being emitted.
[0003] A search revealed that Chinese patent CN212188477U discloses a purification device for treating waste gas in a chemical plant. This utility model has an activated carbon adsorption plate with a funnel structure inside the purification cylinder, which can perform deodorization treatment. Moreover, the particulate matter contained in the waste gas can fall into the storage box for further treatment.
[0004] When the above-mentioned purification equipment is in use, by setting up a water tank and a disinfection tank, the exhaust gas after the odor is treated can be thoroughly purified. The disinfectant inside the disinfection tank, together with the activated carbon adsorption plate, has a relatively ideal purification effect. However, when the disinfectant inside the disinfection tank is low, it needs to be added manually. Therefore, it is necessary to arrange for a dedicated person to regularly check the liquid level in the disinfection tank and perform the addition operation, which results in low work efficiency. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-stage chemical waste gas purification device, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage chemical waste gas purification device, comprising a first chamber, an inclined tube, and a second chamber, wherein both ends of the inclined tube are fixedly connected to the first chamber and the second chamber, respectively; a first connecting pipe is fixedly connected to the other side of the first chamber; a second connecting pipe is fixedly connected to the other side of the second chamber; a partition is fixedly connected inside the first chamber; a water outlet is provided at the top of the partition and is fixedly installed inside the first chamber; a water pipe is fixedly connected to the rear side of the water outlet; a water pump is fixedly connected to the other end of the water pipe and is fixedly installed on the rear side of the first chamber; waterproof switches are fixedly installed at the bottom of the partition and the bottom of the interior of the first chamber; a squeezing assembly is provided between the two waterproof switches; the squeezing assembly includes a sliding plate, two sliding rods, two pressure plates, and multiple airbags; a first water pipe is fixedly connected to one side of the first chamber and at the bottom of the partition; a solenoid valve is fixedly installed on the first water pipe.
[0007] Furthermore, the bottom ends of both sliding rods pass through the slide plate and are fixedly connected to the first housing, the opposite ends of the two pressure plates are fixedly connected to the slide plate, and the multiple airbags are respectively fixedly installed on both sides of the slide plate.
[0008] Furthermore, a second water pipe is fixedly connected to the other side of the first housing and at the top of the partition, and a valve is fixedly installed on the second water pipe.
[0009] As can be seen, in the above technical solution, when the valve is opened, the sewage is discharged into the first tank through the second water pipe.
[0010] Furthermore, both the top of the first and second boxes are fastened with cover plates via buckles, and both cover plates are provided with gaskets.
[0011] As can be seen, in the above technical solution, the activated carbon plate inside the second chamber is opened and cleaned and replaced. Similarly, the cover is installed. The gasket can improve the sealing between the cover and the second chamber.
[0012] Furthermore, an ultraviolet lamp is fixedly installed on the cover plate of the second housing.
[0013] It can be seen that in the above technical solution, the ultraviolet light released when the ultraviolet lamp is working can destroy the DNA structure of microorganisms in the exhaust gas, and at the same time decompose some small molecule organic pollutants that are not adsorbed by activated carbon.
[0014] Furthermore, a heater is fixedly installed on one side of the first housing.
[0015] It can be seen that, in the above technical solution, drying the chemical waste gas can effectively remove the water vapor carried in the chemical waste gas.
[0016] Furthermore, the interior of the second chamber is equipped with three activated carbon plates.
[0017] It can be seen that the above technical solution adsorbs organic pollutants and residual odors in chemical waste gas layer by layer, thereby further purifying the chemical waste gas.
[0018] The technical effects and advantages of this utility model are as follows:
[0019] 1. This utility model sprays disinfectant downwards through the water outlet, which can initially purify chemical waste gas. The slide plate floats on the disinfectant. As the disinfectant gradually decreases, the slide plate drives two pressure plates to move downwards. When one of the pressure plates squeezes one of the waterproof switches, the waterproof switch can open the solenoid valve, so that water in the external water pipe enters the first tank through the first water pipe. The operation is simple, no manual addition of disinfectant is required, and work efficiency is improved.
[0020] 2. This utility model dries chemical waste gas through the operation of a heater, which can effectively remove the water vapor carried in the chemical waste gas and avoid the water vapor affecting the adsorption efficiency of the subsequent activated carbon plates. Three activated carbon plates further purify the chemical waste gas, and ultraviolet lamps purify the chemical waste gas again. Finally, the chemical waste gas that has been purified multiple times is discharged into the second chamber through the second connecting pipe. The multi-stage treatment structure is convenient to use. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] Refer to the instruction manual appendix Figure 1-5 This embodiment of a multi-stage chemical waste gas purification device includes a first housing 1, an inclined tube 3, and a second housing 4. The two ends of the inclined tube 3 are fixedly connected to the first housing 1 and the second housing 4, respectively. A first connecting pipe 2 is fixedly connected to the other side of the first housing 1, and a second connecting pipe 5 is fixedly connected to the other side of the second housing 4. A partition 18 is fixedly connected inside the first housing 1, and a water outlet hopper 17 is provided at the top of the partition 18. The water outlet hopper 17 is fixedly installed inside the first housing 1, and a water pipe is fixedly connected to the rear side of the water outlet hopper 17. 14. The other end of the water pipe 14 is fixedly connected to the water pump 13, and the water pump 13 is fixedly installed on the rear side of the first box 1. Waterproof switches 19 are fixedly installed at the bottom end of the partition 18 and the bottom inside of the first box 1. A squeezing assembly 20 is provided between the two waterproof switches 19. The squeezing assembly 20 includes a sliding plate 201, two sliding rods 202, two pressure plates 203 and multiple airbags 204. A first water pipe 9 is fixedly connected to one side of the first box 1 and at the bottom of the partition 18. A solenoid valve 10 is fixedly installed on the first water pipe 9.
[0030] Furthermore, the bottom ends of the two sliding rods 202 pass through the slide plate 201 and are fixedly connected to the first housing 1. The opposite ends of the two pressure plates 203 are fixedly connected to the slide plate 201. Multiple airbags 204 are fixedly installed on both sides of the slide plate 201. A second water pipe 11 is fixedly connected to the other side of the first housing 1 and at the top of the partition 18. A valve 12 is fixedly installed on the second water pipe 11.
[0031] Furthermore, the top of both the first box 1 and the second box 4 are fastened with cover plates 6 by buckles, and gaskets 7 are provided on both cover plates 6. An ultraviolet lamp 8 is fixedly installed on the cover plate 6 of the second box 4. A heater 15 is fixedly installed on one side of the first box 1. Three activated carbon plates 16 are provided inside the second box 4. A support plate is provided in the second box 4. The upper part of the support plate and the lower part of the cover plate 6 are provided with grooves that correspond to each other. The activated carbon plates 16 are placed in the grooves.
[0032] In this system, the chemical waste gas in the first chamber 1 enters the second chamber 4 through the inclined tube 3. The heater 15 dries the chemical waste gas, effectively removing the water vapor carried in it and preventing it from affecting the adsorption efficiency of the activated carbon plates 16. The three activated carbon plates 16 adsorb organic pollutants and residual odors in the chemical waste gas layer by layer, further purifying the gas. The ultraviolet lamp 8 consists of a lamp holder and a lamp fixture, with the fixture located inside the second chamber 4 and the lamp holder on the cover plate 6. When the second chamber 4 is a closed space, the ultraviolet lamp 8 is activated. The ultraviolet light released during operation can destroy the DNA structure of microorganisms in the exhaust gas and decompose some small molecule organic pollutants that are not adsorbed by activated carbon. The ultraviolet light lamp 8 irradiates for 20 minutes, which further purifies the chemical exhaust gas. Finally, the chemical exhaust gas that has been purified multiple times is discharged into the second chamber 4 through the second connecting pipe 5. The multi-stage treatment structure is easy to use. Open the cover plate 6 and take out the activated carbon plate 16 in the second chamber 4. Clean and replace the activated carbon plate 16. Similarly, install the cover plate 6. The gasket 7 can improve the sealing between the cover plate 6 and the second chamber 4.
[0033] The usage method of this embodiment is as follows:
[0034] In use, the external pipe flange is connected to the flange on the first connecting pipe 2 using bolts. Chemical waste gas enters the first chamber 1 through the first connecting pipe 2. The water pump 13 is started, drawing disinfectant from the first chamber 1 and injecting it into the water outlet 17 through the water pipe 14. The water outlet 17 sprays the disinfectant downwards, thus performing preliminary purification of the chemical waste gas. Four airbags 204 increase the buoyancy of the slide plate 201, allowing it to float on the disinfectant. Two sliding rods 202 limit the deflection of the slide plate 201. As the disinfectant gradually decreases, the slide plate... 201 drives two pressure plates 203 to move downwards. When one of the pressure plates 203 squeezes one of the waterproof switches 19, the waterproof switch 19 can open the solenoid valve 10, so that water in the external water pipe enters the first tank 1 through the first water pipe 9. When the water level increases, the slide plate 201 begins to move upwards. When the other pressure plate 203 squeezes the other waterproof switch 19, the waterproof switch 19 can close the solenoid valve 10. The operation is simple, no manual addition of disinfectant is required, and the work efficiency is improved. When the valve 12 is opened, the sewage is discharged into the first tank 1 through the second water pipe 11.
[0035] The chemical waste gas in the first chamber 1 enters the second chamber 4 through the inclined pipe 3. The heater 15 dries the chemical waste gas, and three activated carbon plates 16 adsorb organic pollutants and residual odors in the chemical waste gas layer by layer, further purifying the chemical waste gas. The ultraviolet lamp 8 is turned on to purify the chemical waste gas again. Finally, the chemical waste gas that has been purified multiple times is discharged from the second chamber 4 through the second connecting pipe 5 for the next step.
