Problems solved by technology

[0007] The water mist sprayed by the sprayer directly falls on the bottom of the desulfurization tower and will cause corrosion to the desulfurization tower; due to the method of spraying water mist to the industrial waste gas, due to the gravity of the water mist, and considering the waste gas discharged into the desulfurization tower The speed and the rising speed of exhaust gas often require a large amount of water to achieve a considerable desulfurization effect, which leads to the waste of water resources. The present invention provides a high-efficiency circulating industrial desulfurization device based on ion exchange

Abstract

A high-efficiency circulating industrial desulfurization device based on ion exchange, including a tower body with a vertical interior and a vertical inner wall. The interior of the tower body is divided into an upper layer area and a lower layer area. The second spray port, flue gas outlet, several first gas outlets and recessed wells; the lower layer area includes an outer casing, the bottom of which is stored with working solution, the outer casing is stored with lime water, and the tower wall of the lower layer area is provided with a cation exchange membrane. The cation exchange membrane connects the lower layer area with the outer casing; the outer casing includes graphite electrodes, water inlets and gas outlets; the tower wall of the tower body is provided with gas pipelines and water pipelines, and the water pipelines are respectively connected to the water inlet and the first spray outlet The present invention generates water by electrolysis of hydroxide ions, thereby forming a water cycle, thereby reducing resource consumption, and prolonging the time for waste gas to remain in the tower body through the inclined wall of the concave well, thereby greatly prolonging the time of the desulfurization process, thereby increasing the waste gas degree of desulfurization.

Description

technical field [0001] The invention relates to the field of industrial desulfurization, in particular to a high-efficiency circulation industrial desulfurization device based on ion exchange. Background technique [0002] Desulfurization generally refers to the process of removing sulfur from fuel before combustion and desulfurization before flue gas emission. It is one of the important technical measures to prevent and control air pollution. At present, there are generally three desulfurization methods: pre-combustion, in-combustion and post-combustion desulfurization. With the development of industry and the improvement of people's living standards, the thirst for energy is also increasing, and SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become an urgent task for the governance of atmospheric environment. Many flue gas desulfurization processes have been widely used in industry, and it also has important practical s...
