Special high-efficiency separation equipment for chilling-type oil removal and dust reduction of pyrolysis gas

The utility model discloses special high-efficiency separation equipment for chilling-type oil removal and dust reduction of pyrolysis gas. The special high-efficiency separation equipment comprises a shell as well as a liquid distributor, a venturi scrubber, a cyclone separator and a liquid collection tank which are arranged inside the shell. The special high-efficiency separation equipment for chilling-type oil removal and dust reduction of the pyrolysis gas can be used for treating high-temperature pyrolysis raw coke oven gas; moreover, washing water and cooling water can be effectively recycled for circulation use, and the purpose of recycling an oil product through deposition is achieved. The special high-efficiency separation equipment for chilling-type oil removal and dust reduction of the pyrolysis gas is simple in structure and easy to maintain; by the equipment, the high-temperature pyrolysis raw coke oven gas can be sufficiently cooled and purified to reduce the possibility that the equipment is blocked; and the separated tar can be recycled to a maximum extent.
