Abstract

The invention discloses a flue gas desulfurization device. The flue gas desulfurization device comprises a desulfurization tower body, a wet filtering assembly, a spraying assembly and a gas distributing assembly, wherein the wet filtering assembly is arranged in the desulfurization tower body; the spraying assembly is used for supplying absorbing liquid to the desulfurization tower body; the gasdistributing assembly is used for conveying to-be-treated flue gas into the desulfurization tower body; the wet filtering assembly comprises a plurality of box filters which are arranged along the height direction of the desulfurization tower body in a stacked way; and microporous structures which are arranged densely and run through the main bodies of the box filters are arranged on the box filters and are used for flue gas to pass through. According to the flue gas desulfurization device provided by the invention, on one hand, through the box filters, complete contact of the flue gas and theabsorbing liquid can be guaranteed and the desulfurization effect of the flue gas is effectively improved; and on the other hand, spiraling gas flow is formed through the gas distributing assembly, so the desulfurization effect can be further improved and the desulfurization efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a flue gas desulfurization device. Background technique [0002] With the development of our country's economy and the progress of society, the problem of environmental protection is becoming more and more serious. Now the problem of acid rain is an important issue of national prevention and control. The main component of acid rain is sulfur dioxide. There is a large amount of SO in power plant flue gas, coke oven flue gas, boiler flue gas, and steel plant flue gas 2 , SO 3 , so these flue gases need to be desulfurized. The desulfurization processes currently used mainly include dry process and wet process. [0003] The wet process has fast reaction speed, high efficiency, and high utilization rate of desulfurization additives. It is widely used. Usually, calcium hydroxide and other slurries are used as the absorption liquid and sprayed countercurrently with the gas...
