Double-loop flue gas desulfurization tower

Abstract

The invention relates to the technical field of flue gas desulfurization, and concretely relates to a double-loop flue gas desulfurization tower. The tower comprises a solution box, the upper surface of the solution box is fixedly connected with a tower body and a water pump, the water inlet end of the water pump is fixedly connected with a liquid inlet pipe, and the water outlet end of the water pump is fixedly connected with a liquid outlet pipe. A spraying device is fixedly connected to the inner top wall of the tower body, a filtering device is fixed to the inner wall of the tower body, a brushing device is slidably connected to the surface of the filtering device, and the brushing device is rotatably connected with the spraying device through a double-crank sliding block mechanism. According to the double-loop flue gas desulfurization tower, an electric push rod is arranged to conveniently drive a right-angle rod to move rightwards, the right-angle rod conveniently drives a concentric-square-shaped frame to move rightwards, and then a filter screen is driven to push rightwards, so that sediments such as gypsum fall into a funnel, and impurities such as gypsum are conveniently taken out by the funnel and then are treated in a centralized manner; therefore, the problems that more impurities such as gypsum are generated during industrial flue gas desulfurization, the labor intensity of manual cleaning is high, and centralized treatment is difficult are solved.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a double-circuit flue gas desulfurization tower. Background technique [0002] With the development of industry, more and more industrial waste gas is produced. If these waste gases are directly discharged into the air, they will cause air pollution and even form acid rain. Therefore, it is necessary to desulfurize industrial waste gas; desulfurization generally refers to desulfurization before combustion Desulfurization in fuel and the desulfurization process before flue gas emission are one of the important technical measures to prevent and control air pollution. [0003] When the flue gas fed into the industrial flue gas desulfurization meets the alkaline desulfurization solution, more gypsum and clods will be produced, which will fall into the desulfurization solution tank, making it dirty and messy, which will affect the next use. Cleaning is usually done ma...
