Waste gas smoke separation device

A waste gas and smoke separation device comprises a mixing chamber, a variable-diameter chamber and a condensation chamber which are arranged from bottom to top, a mixing structure and an inclined baffle are arranged in the mixing chamber, a contraction section of the variable-diameter chamber is filled with a filter material, a filter screen and an anti-blocking structure are arranged on a diffusion section of one end, close to the condensation chamber, of the variable-diameter chamber, and a condensation structure is arranged on the top, away from the filter screen, of the condensation chamber. An activated carbon layer is vertically arranged at one end, far away from the condensation structure, of the outlet side of the condensation chamber. According to the waste gas and smoke separation device, the gas washing effect is achieved through the arranged mixing chamber, the water consumption is reduced, large water drops and small-diameter solid particles in a waste gas mixture are comprehensively removed thr
