Waste gas purification environment-friendly equipment capable of improving gas purification rate

Disclosed waste gas purification environment-friendly equipment capable of improving a gas purification rate comprises a box body and a connecting pipe, an air inlet is formed in one side of the box body, an ash removal barrel is movably installed at the bottom end of the box body, a filter drum is rotatably connected to the inner wall of the box body, and a fan is fixedly installed in the box body. The surface of the connecting pipe communicates with a first exhaust pipe and a second exhaust pipe, a rotating block is rotatably mounted on the inner wall of the connecting pipe, a sliding block is fixedly connected to the surface of the rotating block, and the bottom end of the second exhaust pipe communicates with a sterilization box. The temperature in the sterilization box is increased through the arranged heating pipe, when waste gas which is primarily purified in the box body flows into the sterilization box, harmful gas in the waste gas is purified through high temperature generated in the sterilization b
