Flue gas treatment device for domestic refuse incineration

Abstract

The invention discloses a flue gas treatment device for domestic refuse incineration, which comprises a quick cooling device, a high-temperature dust remover, a plasma device and a chemical cleaning device, wherein the high-temperature dust remover comprises a backflush gas storage tank, a pulse valve, a distributing duct, a cleaned gas chamber and a crude gas chamber; the plasma device comprises a device body, a knife switch, a temperature control device, a blower and a plasma module based on needle-cylinder corona discharge technique. The flue gas treatment device for domestic refuse incineration is reasonable in design; the high-temperature dust remover is used instead of cyclone dust removal and atomization dust removal; and the plasma device is utilized to perform catalytic treatment on dioxin compounds instead of the activated carbon adsorption technique, thereby simplifying the structure, lowering the device cost and reducing the device occupied area. The flue gas treatment device for domestic refuse incineration is safe and reliable to use, avoids secondary pollution and greatly lowers the operating cost, and the dioxin compound reduction and conversion efficiency is up to 81%, thereby achieving the long-term stable effect of discharge after reaching the standard. The treatment flow rate is high; and when the blower speed is 8 m / s, the treated glue gas amount is 73728 cubic meters per hour.

Description

technical field [0001] The invention relates to a flue gas treatment device, in particular to a flue gas treatment device for domestic waste incineration. Background technique [0002] In the existing domestic waste incineration technology, the flue gas treatment device is a very important part of it. If the emission of incineration flue gas does not meet the standard, this technology will be rejected and it will be difficult to apply. The harmful components in the flue gas emitted after garbage incineration are very complex, and the most difficult to deal with are dioxin-like compounds. Dioxin-like compounds are highly toxic organic substances that have serious damage and harm to ecosystems such as soil and water. When these compounds pass through water, when the land food chain accumulates to a certain extent, the harm will be more serious. The traditional flue gas treatment process uses high-temperature oxidation and rapid cooling to reduce the temperature, and after dus...

AI Technical Summary

Problems solved by technology

Due to the high water content in the gas, the activated carbon will quickly fail and block, making the system unable to operate normally. This activated carbon adsorption and dust removal system cannot achieve long-term stable and standard discharge, and produces secondary pollution and high operating costs.
