Flue gas system and control method

Tobacco smoke electrostatic precipitator receiving, separating and collecting dust in the flue gas, the transfer by the Joint fan dust treatment; one kind of flue gas systems, including electrostatic precipitators, the United fans, and flue gas desulphurization system discharge means gas, combined with the fan is provided with a regulating unit to adjust the control unit in accordance with the United fans suffered smoke during transmission output resistance, wet desulfurization apparatus includes a plurality of slurry circulating pump and placing slurry-absorber slurry circulating pump installed in the absorber, the absorber and the United fan inlet connected to receive flue gas absorber inlet joint fan delivery of flue gas desulfurization, flue gas exhaust flue gas desulfurization by means discharge treated; in the transmission according to the flue gas by the resistance during the joint control of the fan output power adjustment object single, joint fans can quickly and accurately provide the required conveying force to maintain the pressure balance flue system to prevent an explosion, to improve security. Also provides a method of controlling the flue gas system.
