Patent Abstract: The utility model discloses a polypropylene tail gas recovery and treatment device, including a base plate fixedly connected to the top surface, a collection box fixedly connected to the top surface of the base plate, a connecting pipe fixedly connected to the top surface of the collection box, a filter net fixedly connected inside the collection box, absorption cotton fixedly connected inside the collection box, activated carbon layer fixedly connected inside the collection box, and a baffle fixedly connected inside the collection box. This device, through the cooperation of water pump, cooling liquid pipe, cooling liquid tank, chiller, and heat dissipation net, can continuously remove heat generated by the compressor inside the collection box, saving operating costs. It solves the problem of excessive heat from the compressor that cannot be dissipated in time, which reduces its service life and increases the cost of using the polypropylene tail gas recovery and treatment device. The combined use of activated carbon layer, filter net, and absorption cotton can absorb and isolate particles, oil stains, and toxic gases produced by the tail gas.
