Black-process asphalt flue gas purification system

The utility model relates to a black-process asphalt flue gas purification system, and belongs to the technical field of flue gas purification. Comprising a coke powder storage tank and an air conveying device, a flue gas inlet of a Venturi mixing reactor is communicated with a flue gas collecting pipe through a first pipeline heater, a flue gas outlet of the Venturi mixing reactor is communicated with a flue gas inlet of a cyclone separator through a pipeline A, a regulating valve is installed on the pipeline A, and a gas outlet of the cyclone separator is communicated with a gas outlet of the Venturi mixing reactor. A flue gas outlet of the cyclone separator is communicated with a flue gas inlet of the bag-type dust collector through a second pipeline, a second pipeline heater is mounted on a feed port of the Venturi mixing reactor, and the coke powder storage tank is communicated with the second pipeline heater through an air conveying device. The device has the following beneficial effects that the first
