Wet flue gas desulfurization system

Abstract

The invention relates to a wet flue gas desulfurization system which comprises desulfurization equipment and condensing equipment which are sequentially connected along a flue gas flowing direction, as well as a cooling water circulation assembly connected with the condensing equipment and a water supplementing and conveying assembly connected with the cooling water circulation assembly and the desulfurization equipment, wherein the cooling water circulation assembly can recycle cooling water in the condensing equipment and send the cooling water back into the condensing equipment so that the condensing equipment can condense flue gas through the cooling water, and the water supplementing and conveying assembly can recycle the cooling water overflowing from the cooling water circulation assembly and send the cooling water into the desulfurization equipment. According to the wet flue gas desulfurization system, the problem that a large amount of water needs to be supplemented in the flue gas desulfurization process of the wet flue gas desulfurization system can be solved, so that the consumption of water resources can be reduced, and the production cost of enterprises can also be reduced.

Description

technical field [0001] The invention belongs to the technical field of wet flue gas desulfurization, and in particular relates to a wet flue gas desulfurization system. Background technique [0002] As we all know, sulfur oxides are one of the main causes of air pollution and acid rain. In recent years, with the continuous enhancement of people's awareness of environmental protection and the continuous improvement of national environmental protection-related policies and regulations, relevant departments and enterprises have also taken measures to control the emission of sulfur oxides. Desulfurization of the flue gas to be discharged is one of the main measures to control the emission of sulfur oxides. The existing flue gas desulfurization technologies mainly include wet flue gas desulfurization technology, semi-dry flue gas desulfurization technology and dry flue gas desulfurization technology. Gas desulfurization technology. [0003] Among them, the wet flue gas desulfur...
