[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] A twin-screw granulator is a plastic processing device that uses two parallel screws. Through the meshing and conveying action of the two screws, it continuously processes plastic raw materials under high temperature and pressure, including conveying, melting, mixing, venting, plasticizing, metering, and pelletizing. This allows for the recycling of plastic waste or the production of virgin materials. It is characterized by high efficiency, energy saving, environmental friendliness, and ease of operation, and is widely used in the plastics processing industry. However, this equipment generates waste gas containing volatile organic compounds, smoke, and incompletely burned organic gases during operation. Currently, filtration equipment is typically installed to treat this waste gas. However, since the filter elements of these filtration devices usually need to be replaced periodically, which often requires machine shutdown, this affects normal granulation efficiency. Therefore, a waste gas purification device is proposed to solve the above problems. Utility Model Content
