Embodiment Construction

[0014] After municipal solid waste enters the pyrolysis combustion device, the flue gas 1 produced after a series of processes such as drying, pyrolysis, and oxidative decomposition enters the pyrolysis chamber through the return pipe for high-temperature flue gas utilization 2 as a heat source for waste pyrolysis Supplement, reduce energy consumption in the pyrolysis process; then discharge into the garbage drying room for flue gas cooling and reuse 3, make full use of the heat energy in the flue gas to dry the garbage, reduce the moisture content, and at the same time achieve the effect of flue gas cooling Purpose: The flue gas after cooling is discharged from the garbage pyrolysis combustion device, and enters the alkali washing tank for alkali washing of the flue gas 4 to remove acid gas and dust in the flue gas; the flue gas after alkali washing is dehydrated for flue gas drying 5 , to remove the water vapor mixed in the flue gas; after the dried flue gas is tested to meet...

Abstract

The invention provides a smoke treatment process used for garbage incineration. The smoke treatment process aims at overcoming the defect that a smoke treatment process used for garbage incineration in the prior art is not reasonable, and consequently the removing effect on harmful substances in smoke is poor. The invention aims at providing a technical method for treating incineration smoke, and the method can be used for effectively conducting stabilized treatment on incineration smoke with complex composition variation.

Description

technical field [0001] The invention relates to the field of environmental energy, in particular, the invention relates to a process for treating incineration flue gas. Background technique [0002] Garbage incineration is an effective way to realize the harmlessness, reduction, and recycling of garbage, but it will inevitably produce toxic and harmful gases such as sulfur dioxide, dioxin, and heavy metals, among which dioxin is a strong carcinogen. The danger of heavy metals is that they cannot be decomposed by microorganisms and can be enriched in organisms, and eventually cause harm to the human body through the food chain, leading to cancer and various diseases; and heavy metals can also pollute soil, water and the atmosphere, causing serious damage to the environment. [0003] In the prior art, activated carbon is often used to treat the flue gas produced by waste incineration. Activated carbon is an adsorbent that contains a large number of micropores and has a large s...
