[0002] In the production of pigment masterbatch, substrates such as PET need to be heated and melted and extruded into pellets with pigments; the tail gas generated during the heating and melting process carries solvents, additives, substrate particles, etc. At the same time, this tail gas is high-temperature tail gas, with a temperature generally above 200°C, and it needs to be dust-removed, absorbed, and cooled before being discharged. Wet dust removal is to make the waste gas come into close contact with a liquid (usually water) to separate pollutants from the waste gas. It can not only purify solid particle pollutants in the waste gas, but also remove gaseous pollutants, and at the same time play a role in cooling the gas. However, in the process of using the traditional tail gas treatment device for polymer masterbatch production, the problem of not being able to filter the circulating gas reduces the thoroughness of filtering harmful substances in the device. Therefore, we redesigned a tail gas treatment device for polymer masterbatch production. Content of the Utility Model
