[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A waste gas treatment device for the preparation of benzenesulfonyl chloride is disclosed in this application. The spray frame 3, collection and treatment box 11 and filter plate 15 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. The device includes a treatment box 1, an air inlet pipe 2 is inserted and installed on the front surface of the treatment box 1, a spray assembly is installed on the back of the air inlet pipe 2 through the front surface of the treatment box 1, a treatment assembly is installed inside the treatment box 1, and an emission assembly is installed on the back of the treatment box 1.

[0027] The spray assembly includes a spray frame 3, a top plate 4 is installed on the top surface of the spray frame 3, the spray frame 3 is installed on the back of the air inlet pipe 2, and a connecting pipe 5 is installed on the left side of the top plate 4.

[0028] The treatment assembly includes an inclined plate 8, which is installed on the inner wall of the treatment chamber 1. A conveying groove 9 is formed on the surface of the inclined plate 8. An mounting plate 6 is installed at the lower end of the top plate 4, and an atomizing spray pipe 7 is installed at the lower end of the mounting plate 6. First, the exhaust gas enters the interior of the treatment chamber 1 through the air inlet pipe 2. Then, the exhaust gas is conveyed through the air inlet pipe 2 to the area below the spray frame 3. Next, the treatment liquid is conveyed to the interior of the top plate 4 through the connecting pipe 5. The treatment liquid is then atomized and sprayed through the atomizing spray pipe 7, thus enabling the entire conveyed exhaust gas to be sprayed, preventing any omissions in the spraying process. Therefore, this setup, through the spray assembly, can uniformly convey and spray the exhaust gas, ensuring that the sprayed treatment liquid makes comprehensive contact with the exhaust gas, resulting in a more thorough overall treatment.

[0029] The front surface of the treatment chamber 1 is provided with a guide groove 10, which is inclined. A collection and treatment box 11 is installed on one side of the surface of the treatment chamber 1, and a conveying pipe 12 is installed on the right side of the collection and treatment box 11. When the spraying assembly continuously sprays, the sprayed treatment liquid can be guided and conveyed by the inclined plate 8. Then, the treatment liquid will flow downward through the conveying groove 9, and then be guided by the guide groove 10, so that the sprayed treatment liquid can be collected into the collection and treatment box 11. Then, the collected treatment liquid can be uniformly transported and processed through the conveying pipe 12.

[0030] The discharge assembly includes a discharge frame 13, which is mounted on the back of the treatment chamber 1. A mounting groove 14 is provided inside the discharge frame 13, and a filter plate 15 is inserted and installed inside the mounting groove 14. A sealing plate 16 is installed on the top surface of the filter plate 15. A mounting base 17 is mounted on the upper surface of the discharge frame 13, and a rotating plate 18 is rotatably mounted inside the mounting base 17. The exhaust gas after being sprayed by the spray assembly is discharged through the discharge frame 13. At this time, a filter plate 15 is inserted and installed inside the installation slot 14. The filter plate 15 can also filter some impurities in the exhaust gas. There are two sets of filter plates 15 and installation slot 14. When one set of filter plates 15 is cleaned, one set continues to filter, so that the filtration operation can be continuous. After the filter plate 15 is installed inside the installation slot 14, the sealing plate 16 will be attached to the top surface of the discharge frame 13. Then, by rotating the rotating plate 18 inside the mounting base 17, it can abut against the top surface of the sealing plate 16, fixing the position of the sealing plate 16. At this time, the sealing plate 16 can seal the entire installation slot 14. Therefore, this setting, through the cooperation of the treatment component and the discharge component, can not only guide and transport the treated liquid after spraying for collection and subsequent unified treatment, but also continuously filter the discharged exhaust gas, resulting in good overall performance.

[0031] Working principle: When the staff uses this device, first connect the device to an external power source to provide power support. First, the exhaust gas enters the interior of the treatment box 1 through the air inlet pipe 2. Then, the exhaust gas will be transported together through the air inlet pipe 2 to the bottom of the spray rack 3. Then, the treatment liquid is transported to the interior of the top plate 4 through the connecting pipe 5. Then, the treatment liquid will be atomized and sprayed through the atomizing spray pipe 7, so that the entire transported exhaust gas can be sprayed.

[0032] When the spray assembly continuously sprays, the treated liquid after spraying is guided and transported by the inclined plate 8. The treated liquid then flows downwards through the conveying trough 9 and is guided again through the guiding trough 10, thus collecting the treated liquid into the collection and treatment tank 11. The collected treated liquid is then transported and processed uniformly through the conveying pipe 12. Simultaneously, the exhaust gas after spraying by the spray assembly is discharged through the discharge frame 13. A filter plate 15 is installed inside the installation tank 14, which can further filter some of the waste gas. Impurities in the exhaust gas are filtered, and two sets of filter plates 15 and mounting grooves 14 are provided. When one set of filter plates 15 is cleaned, one set continues to filter, thus enabling continuous filtration. After the filter plates 15 are installed inside the mounting grooves 14, the sealing plate 16 will adhere to the top surface of the discharge frame 13. Then, by rotating the rotating plate 18 inside the mounting base 17, it can abut against the top surface of the sealing plate 16, fixing the position of the sealing plate 16. At this time, the sealing plate 16 can seal the entire mounting groove 14. The above is the working principle of this utility model.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
