Exhaust gas purifier

Abstract

The invention belongs to the field of environmental protection and especially relates to an environmentally friendly exhaust gas purifier. The environmentally friendly exhaust gas purifier comprises an air inlet pipe, a deduster, an exhaust pipe and an exhaust chimney, which are communicated successively. Upper dedusting baffle plates and lower dedusting baffle plates are arranged inside the deduster. The upper dedusting baffle plates and the lower dedusting baffle plates are arranged at intervals and in a staggered manner. The upper dedusting baffle plates are suspended on the upper inner wall of the deduster. The lower dedusting baffle plates are fixed on the lower inner wall of the deduster. The outer wall of the exhaust pipe is provided with a spray device. The invention aims to provide an environmentally friendly exhaust gas purifier which is simple to manufacture and install, occupies small area, is economic and practical and is beneficial to process toxic gas and dust generated during combustion process of fire coal. By the environmentally friendly exhaust gas purifier, the pollution problem of exhaust gas is effectively solved, and atmospheric environment is protected.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to an environment-friendly 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 th...
