Asphalt flue gas coke powder injection, adsorption and purification device

The invention discloses an asphalt flue gas coke powder injection adsorption purification device which comprises an injection adsorption device and a dust removal device, the jet adsorption device comprises an adsorption reactor, an automatic feeding device, a front Venturi ejector and a rear Venturi ejector; a pipe diameter adjusting mechanism is arranged at the middle position below the front venturi ejector and the rear venturi ejector; an inlet of the dust removal device is communicated with the top of the adsorption reactor through a first flue gas pipeline, and an outlet of the dust removal device is connected with the desulfurization treatment device through a second flue gas pipeline. According to the asphalt flue gas coke powder jet adsorption purification device, high-temperature flue gas generated by a calcination system is used for heating low-temperature flue gas and petroleum coke powder, the flow of the high-temperature flue gas entering the adsorption reactor is automatically adjusted accordin
