[0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before it is discharged to meet emission standards. Generally, waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment, and air sterilization, disinfection and purification.

[0003] For example, CN213348284U discloses a device for treating and discharging tail gas from the reaction of ammonia and p-chlorotoluene. The device includes a main body with a base at its bottom. A water treatment chamber is fixedly connected to the upper surface of the base. A faucet is inserted into one outer surface of the main body. An exhaust pipe is inserted inside the water treatment chamber. A connecting pipe is fixedly connected to the upper outer surface of the exhaust pipe, and a blower is fixedly connected to the left outer surface of the connecting pipe. In this invention, the filter screen, connecting pipe, and water treatment chamber enable water absorption treatment of the waste gas. After the waste gas enters the water treatment chamber through the exhaust pipe, it undergoes water absorption treatment. The process is simple, easy to manage, and has low operating costs. The filter screen and activated carbon ensure that the waste gas undergoes activated adsorption treatment before passing through the water treatment chamber, guaranteeing high efficiency in tail gas treatment.

[0004] However, in existing technologies, many devices only use adsorption or only use thermal oxidation treatment. A single process is not enough to efficiently remove harmful substances from exhaust gas, causing air pollution and thus limiting the practicality of the device to a certain extent.

[0009] In a preferred embodiment, an inlet pipe is fixedly installed on one side of the outer surface of the processing box above the second chamber, and a third solenoid valve is installed on the surface of the inlet pipe.

[0010] In a preferred embodiment, a drain pipe is fixedly installed on the other side of the outer surface of the processing box, located below the second chamber, and a fourth solenoid valve is installed on the surface of the drain pipe.

[0011] In a preferred embodiment, an exhaust pipe is fixedly provided on the other side of the upper surface of the second mounting plate.

[0012] In a preferred embodiment, the interior of the filter cartridge is sequentially provided with a particle adsorption layer, an impregnation adsorption layer, and a polishing adsorption layer from the inlet to the outlet.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a treatment and emission device for the tail gas of the reaction between ammonia and p-chlorotoluene, comprising a treatment box 1, the inner cavity of which is respectively provided with a first chamber 2 and a second chamber 10. A first mounting plate 3 is fixedly installed on the upper surface of the first chamber 2 by bolts, and a second mounting plate 11 is fixedly installed on the upper surface of the second chamber 10 by bolts. Water is added to the inside of the first chamber 2, and a weak acid is added to the inside of the second chamber 10. A serpentine pipe 4 is fixedly installed on the surface of the first mounting plate 3, and the outlet of the serpentine pipe 4 is fixedly connected to a first bend pipe 5 by a flange and locking bolts. A blower 17 is fixedly installed on one side of the upper surface of the mounting plate 11. A second bend 19 is fixedly installed at the input end of the blower 17, and a connecting pipe 18 is fixedly installed at the output end of the blower 17. The bottom end of the connecting pipe 18 is immersed in a weak acid. A filter cartridge 20 is pre-fixed between the first bend 5 and the second bend 19 through a flange and locking bolts. The exhaust gas enters the first chamber 2 through the serpentine pipe 4 for cooling and heat exchange, and is first filtered by the blower 17 through the filter cartridge 20 before being discharged into the weak acid for neutralization and conversion, thereby enhancing the exhaust gas treatment effect.

[0024] like Figure 1-4 As shown, a water inlet pipe 6 is fixedly installed on one side of the outer surface of the treatment box 1 above the first chamber 2, and a first solenoid valve 7 is installed on the surface of the water inlet pipe 6. A drain pipe 8 is fixedly installed on the other side of the outer surface of the treatment box 1 below the first chamber 2, and a second solenoid valve 9 is installed on the surface of the drain pipe 8. By installing the water inlet pipe 6 and the drain pipe 8 on the outer surface of the treatment box 1 respectively, and equipping it with the first solenoid valve 7 and the second solenoid valve 9, the treatment box 1 realizes precise control and automatic adjustment of water flow, optimizes water circulation and discharge management, and improves system efficiency and stability.

[0025] like Figure 1-4 As shown, an inlet pipe 13 is fixedly installed on one side of the outer surface of the treatment tank 1 above the second chamber 10, and a third solenoid valve 14 is installed on the surface of the inlet pipe 13. A drain pipe 15 is fixedly installed on the other side of the outer surface of the treatment tank 1 below the second chamber 10, and a fourth solenoid valve 16 is installed on the surface of the drain pipe 15. The treatment tank 1 is equipped with an inlet pipe 13 and a drain pipe 15 above and below the second chamber 10, and is equipped with a third solenoid valve 14 and a fourth solenoid valve 16, which realizes precise control and automated management of liquid, and improves circulation efficiency and system stability.

[0026] like Figure 1-4As shown, an exhaust pipe 12 is fixedly installed on the other side of the upper surface of the second mounting plate 11. The filter cartridge 20 is sequentially fixed with a particle adsorption layer 21, an impregnated adsorption layer 22, and a polished adsorption layer 23 from the inlet to the outlet. The exhaust pipe 12, together with the graded purification design of the particle adsorption layer 21, the impregnated adsorption layer 22, and the polished adsorption layer 23 inside the filter cartridge 20, can efficiently remove pollutants and extend the life of the adsorption layer, ensuring clean and stable exhaust.

[0027] Working principle: In use, firstly, the first mounting plate 3 is installed onto the upper surface of the first chamber 2 using locking bolts, and the second mounting plate 11 is installed onto the upper surface of the second chamber 10. Then, the first solenoid valve 7 and the third solenoid valve 14 are opened, water is added to the first chamber 2 through the water inlet pipe 6, and weak acid is added to the second chamber 10 through the liquid inlet pipe 13. Next, one end of the first bend pipe 5 is connected to the outlet of the serpentine pipe 4 using a flange and locking bolts. Then, both ends of the filter cartridge 20 are connected to the first bend pipe 5 and the second bend pipe 19 using flanges and locking bolts. Finally, the inlet of the serpentine pipe 4 is connected to the exhaust port using a flange and locking bolts. Then, the blower 17 is started, and the blower 17 sends the exhaust gas into the first chamber 2 for cooling and heat exchange, which to some extent reduces the formation of subsequent acid. The exhaust gas enters the filter cartridge 20 through the first bend 5. The exhaust gas passes through the particulate adsorption layer 21, the impregnated adsorption layer 22, and the polished adsorption layer 23 for staged adsorption and filtration. The particulate adsorption layer 21 adsorbs non-polar aromatic hydrocarbons, while the impregnated adsorption layer 22 adsorbs VOCs and absorbs a small amount of acidic gases, delaying catalytic / equipment corrosion. The polished adsorption layer 23 further filters and adsorbs the exhaust gas, thereby efficiently removing harmful substances from the exhaust gas. Some of the remaining gas is discharged into the weak acid in the second chamber 10 to react and precipitate, allowing the exhaust gas that meets the emission standards to be discharged to the outside through the exhaust pipe 12. The water circulation is controlled by the water inlet pipe 6 and the water outlet pipe 8 for heat exchange, while the liquid inlet pipe 13 and the liquid outlet pipe 15 allow for convenient replacement of the weak acid in the second chamber 10. The overall operation is convenient, easy to use, and has low maintenance costs, making it suitable for large-scale application and promotion.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
