[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] After the kettle body produces polypropylene, the utility model uses an external water inlet pipe to inject water into the kettle body through a nozzle to cool the polypropylene. After cooling, the water source will be concentrated at the bottom of the inner cavity of the kettle body. At this time, the extraction pump will pump the water source to the inside of the connection shell through the first connecting pipe. At this time, the water source will pass through the activated carbon particles inside the purification shell to remove most of the organic matter and certain sulfur compounds in the water source.
