Smoke sulfur-removing and dust-removing system

Abstract

The invention relates to the technical fields smoke sulfur removal and dust removal, in particular to a smoke sulfur-removing and dust-removing system with high dust-removing and sulfur-removing efficiency, good smoke-purifying effect and stable and reliable operation environment. The smoke sulfur-removing and dust-removing system comprises a dust remover (1), wherein the dust remover (1) is communicated with the lower part of a sulfur-removing and dust-removing tower (2) through an air outlet pipeline (4); the air outlet pipeline (4) extends into the sulfur-removing and dust-removing tower (2); a draught fan (42) is arranged in the middle of the air outlet pipeline (4); a reaction tank (3) is arranged below the sulfur-removing and dust-removing tower (2) and is communicated with the bottom of the sulfur-removing and dust-removing tower (2) through a communicating pipe (5); the reaction tank (3) is communicated with a transfusion pipe (6) for assembling a transfusion pump; three liquid outlet branch pipes (61) are arranged on the transfusion pipe (6); an atomizing device (62) is arranged at the orifice of each liquid outlet branch pipe (61); the two liquid outlet branch pipes (61) on the upper part are communicated with the sulfur-removing and dust-removing tower (2); and the liquid outlet branch pipe (61) at the lower part is communicated with the air outlet pipeline (4) between an impactor (41) and the draught fan (42).

Description

technical field [0001] The invention relates to the technical field of flue gas dedusting and desulfurization, in particular to a flue gas desulfurization and dust removal system. Background technique [0002] Sulfur dioxide is one of the main pollutants in the atmosphere, and it is also an important indicator to measure whether the atmosphere is polluted. The control of sulfur dioxide is extremely important. Especially in our country, when the winter comes, most areas will use coal-fired heating. The coal is often not fully burned, and the billowing smoke carries pollutants such as dust and sulfur dioxide into the air. The city is shrouded in smog, and people's health The control of sulfur dioxide is one of the indispensable prerequisites for ensuring the health of the people. At present, sulfur dioxide control technologies can be basically divided into three categories: desulfurization before combustion, desulfurization during combustion and flue gas desulfurization after...

AI Technical Summary

Problems solved by technology

For the split type wet dedusting desulfurizer, there are mainly two ways to realize it, one is to increase the desulfurization method of the cyclone multi-tube dust collector by adding a spray settling chamber, and the other is to increase the desulfurization method of the multi-tube dust collector by adding a spray chamber. It has the disadvantages of large floor area and many elbows in the flue leading to large pipeline resistance, which makes it unable to operate continuously and normally for a long time; for the integrated wet dust collector, it also has the disadvantages of large floor area, long installation period, and desulfurization of the dust collector. The moisture content of the final flue gas is difficult to control, the operation effect fluctuates greatly, and the desulfurization effect cannot be achieved stably
