Tail gas emission system for waste incineration

Abstract

The invention discloses a tail gas emission system for waste incineration, and belongs to the technical field of waste incineration tail gas treatment. An incinerator, a filtering device, a reaction device, a heating device, a vertical shaft type wind driven generator, a washing tower and a bag type dust collector are sequentially connected through pipelines in a penetrating manner, one-way valves for preventing liquid from flowing backwards are arranged on the pipeline between the filtering device and the reaction device and the pipeline between the vertical shaft type wind driven generator and the washing tower, and a tail gas control valve for controlling tail gas emission is arranged on the pipeline between the incinerator and the filtering device. The filtering device, the reaction device, the heating device and the vertical shaft type wind driven generator are arranged, waste heat and kinetic energy of tail gas are fully utilized, water heating and wind power generation are conducted respectively, hot water and electric power can be used for daily use of enterprises, and the enterprise cost is reduced.

Description

technical field [0001] The invention relates to the technical field of waste incineration tail gas treatment, in particular to a tail gas discharge system for waste incineration. Background technique [0002] The incineration treatment of domestic waste will produce a large amount of tail gas during incineration. These tail gases contain a large number of pollutants, mainly solid particle pollution, and a certain amount of toxic gases, usually acid gases SO2, HCL, etc., among which A large number of solid particles rise into the atmosphere with the hot air, and fall to the ground after cooling, causing a layer of solid particle pollutants to accumulate on the ground or farmland near the waste incineration plant, while toxic gases are directly discharged into the air, directly polluting the air environment, Affect the lives of nearby residents, and even cause cancer in serious cases; [0003] And existing tail gas general processing method is to carry out constant temperatur...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to make full use of the waste heat and kinetic energy of the tail gas by setting the filtering device, the reaction device, the heating device and the vertical axis wind power generator, respectively to heat hot water and wind power generation, and the hot water and electric power can be used for the daily Use to solve the problem that the existing tail gas treatment system cannot fully utilize the heat and kinetic energy of the tail gas. In order to solve the problem, a tail gas discharge system for waste incineration is proposed.
