Double-filtration exhaust gas purification equipment

Abstract

Belonging to the field of environmental protection, the invention in particular relates to double-filtration exhaust gas purification equipment, which consists of an air inlet pipe, a deduster, an exhaust pipe and an exhaust chimney that are communicated in order. The deduster is internally provided with upper activated carbon filter plates and lower activated carbon filter plates, the upper activated carbon filter plates and the lower activated carbon filter plates are arranged staggeredly at an interval, the upper activated carbon filter plates are suspended on the upper end inner wall of the deduster, and the lower activated carbon filter plates are fixed on the lower end inner wall of the deduster. The windward sides of the upper activated carbon filter plates and the lower activated carbon filter plates are all equipped with a filtration grid plate. The deduster bottom is provided with a deslagging door. The exhaust pipe outer wall is equipped with a spray device. The invention aims to provide the double-filtration exhaust gas purification equipment with the advantages of simple manufacturing and installation, small floor space, economical efficiency and practicability. The double-filtration exhaust gas purification equipment is conducive to dispose poisonous gas and dust produced in a fire coal combustion process, effectively solves the waste gas pollution problem, and protects the atmospheric environment.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a dual-filter waste gas purification device. Background technique [0002] With the rapid development of science and technology, people pay more and more attention to the environment, and the environmental emission standards are becoming more and more stringent. A small number of places still use the method of burning coal to exchange for heat energy. The flue gas of coal combustion contains a large amount of acid gas (such as sulfur-containing gas), dust, heavy metals and other pollutants, so the flue gas needs to be purified and controlled. [0003] At present, the most widely used method in flue gas desulfurization is to absorb acid gas in flue gas through absorbent slurry. Due to the relatively high temperature of the flue gas produced by coal combustion, and the relatively complex gas components in the flue gas, there are relatively high requirements for the temperat...
