Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for plastic particle production. Background Art

[0002] A large amount of waste gas will be generated when manufacturing plastic particles. Direct discharge of untreated waste gas will cause serious air pollution, damage the ecology and endanger human health. Therefore, a waste gas treatment device for plastic particle production is needed to treat the waste gas.

[0003] According to the description of a waste gas treatment device for plastic granule production disclosed on the patent website (authorization announcement number: CN218688054 U), "The utility model belongs to the technical field of plastic granulation, and in particular to a waste gas treatment device for plastic granule production. The utility model provides a waste gas treatment device for plastic granule production in which chemical agents and waste gas can fully react. The utility model provides such a waste gas treatment device for plastic granule production, including: a treatment barrel, an L-shaped air inlet pipe, an L-shaped air inlet pipe is embedded in the lower part of the side wall of the treatment barrel, the air outlet end of the L-shaped air inlet pipe is located at the center axis of the treatment barrel, and a liquid outlet pipe is provided at the bottom of the treatment barrel. The waste gas is introduced into the treatment barrel to react with the chemical agent, and the gas in the treatment barrel overflows upward. When the waste gas is introduced into the L-shaped air inlet pipe, it will drive the air wheel to rotate. The air wheel drives the impeller to rotate through the rotating shaft. The rotation of the impeller can pump the chemical agent into the spray pipe through the pipeline, and can spray the waste gas floating upward again. This device is conducive to the full reaction of plastic waste gas and chemical agents."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can pump chemicals into the spray pipe through the pipeline through the rotation of the impeller, and can spray the waste gas floating upward again, and the waste gas is discharged through the small holes of the diffusion cover, and the waste gas fully reacts with the chemicals. However, after the chemicals are sprayed on the top of the dispersion cover and react with the waste gas just sprayed, a large amount of impurities will be generated, which will block the air outlet of the dispersion cover, affecting the discharge of gas and thus affecting the use. Secondly, the device uses the flow of waste gas as a power source to drive the liquid to rise for spraying, and cannot guarantee that the liquid will be sprayed out just after the gas reaches the height of the nozzle. There may be a situation where a small amount of waste gas is directly discharged from the outlet without chemical reaction when it is just introduced, and the liquid will no longer be sprayed if no waste gas is introduced, but there is still gas inside, and the remaining waste gas cannot be treated. Therefore, it is necessary to improve a waste gas treatment device for plastic particle production to solve the above problems. Utility Model Content
