An incinerator exhaust gas purification device

Abstract

The invention discloses an incinerator waste gas purifying device. The incinerator waste gas purifying device comprises an incinerator waste gas purifying device body, and a waste gas inlet pipe communicated with an exhaust port of an incinerator body, wherein the end of the waste gas inlet pipe is communicated with a deduster, an upper dedusting baffle plate and a lower dedusting baffle plate are arranged in the deduster and are arranged in a staggered spacing manner, the end of the deduster is communicated with a waste gas exhaust pipe, the end of the waste gas exhaust pipe is communicated with an exhaust chimney, a left support plate and a right support plate, which are staggered up and down, are arranged on the inner side wall of the exhaust chimney, a flue gas pre-spraying cooling device is arranged on the left support plate, a flue gas spraying desulphurization device is arranged on the right support plate, and a waste gas purifying pond is formed at the bottom of the exhaust chimney. The incinerator waste gas purifying device can be manufactured and installed simply, has small occupied area, can filter toxic gas, heavy metals and dust in a coal burning process, can effectively solve the problem of waste gas pollution, and can avoid explosion danger caused by high pressure inside the device.

Description

technical field [0001] The invention relates to a waste gas purification device, in particular to a waste gas purification device suitable for an incinerator, and belongs to the technical field of environmental protection devices. Background technique [0002] With the rapid development of science and technology, people pay more and more attention to environmental protection, and the requirements for air quality are also getting higher and higher. As a device for incinerating coal or waste in exchange for heat or waste treatment, its combustion The flue gas discharged through the incinerator after burning coal or waste contains a large amount of acid gas (such as sulfur-containing gas), dust, dioxins, heavy metals and other pollutants. If not properly treated, it will cause serious damage to the atmospheric environment. Serious pollution; in order to purify and treat the waste gas discharged from the incinerator, various schemes have been proposed in the prior art, such as t...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention proposes an incinerator exhaust gas purification device, which includes an incinerator body and an exhaust gas inlet pipe connected to the exhaust port of the incinerator body. The upper dust removal baffle and the lower dust removal baffle are arranged in the dust collector, the upper dust removal baffle and the lower dust removal baffle are arranged alternately, the end of the dust collector is connected to the exhaust gas exhaust pipe, and the end of the exhaust gas exhaust pipe is connected to the The exhaust chimney is provided with upper and lower staggered left and right support plates on the inner wall of the exhaust chimney, and the left and right support plates are respectively equipped with a flue gas pre-spray cooling device and a flue gas spray Desulfurization device, the exhaust gas purification pool is formed at the bottom of the exhaust chimney. The invention is simple to manufacture and install, and occupies a small area. It can filter out toxic gases, heavy metals and dust generated during the process of burning coal or waste, and effectively solves the problem of exhaust gas pollution. , and avoid the risk of explosion caused by excessive air pressure inside the device
