Desulfurization equipment for pneumatic emulsification desulfurization tower machine

Abstract

The invention relates to the technical field of flue gas desulfurization, and discloses desulfurization equipment for a pneumatic emulsification desulfurization tower machine. The desulfurization equipment comprises a bottom frame, wherein a water seal chamber is formed in one side of the bottom frame, a tower body is arranged above the bottom frame and is matched with the water seal chamber, andone side of the lower part of the tower body is fixedly sleeved with a gas inlet pipe. According to the desulfurization equipment of the pneumatic emulsification desulfurization tower machine, throughcooperation of a pressing ring and a telescopic column, flue gas flow power is converted into gas pressure, the gas pressure is transmitted to a movable plug, the movable plug is pushed to move, andthen when the flue gas flow is reduced, the movable plug is controlled to move leftwards to enable a gas distribution pipe to communicate with a tower body; a suction fan begins to work to blow air led out of an induced draft fan into the tower body again, so airflow in the tower body is increased, and airflow stability is guaranteed; the power of the suction fan is increased along with increase of the moving distance of a movable plug, so it is guaranteed that an emulsion layer generated by cutting and emulsifying liquid through airflow is stable, and the desulfurization effect of equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a pneumatic emulsification desulfurization tower machine desulfurization equipment. Background technique [0002] In order to solve acid rain, the emission concentration of sulfur dioxide should be controlled, which can generally be achieved by desulfurization methods, which mainly control the concentration of sulfur dioxide emission from coal-fired power plants. The desulfurization methods currently adopted mainly include desulfurization before combustion, desulfurization during combustion, and desulfurization after combustion. Desulfurization before combustion is difficult due to the limitation of coal resources in my country. For desulfurization during combustion, the furnace structure in the boiler chamber should be improved to facilitate the full combustion of coal powder and reduce the production of sulfur dioxide. Desulfurization after combustion is mainly f...
