Comprehensive treatment box for waste incineration flue gas

Abstract

The invention relates to a comprehensive treatment box for waste incineration flue gas. The comprehensive treatment box comprises a box body. The box body is divided into a secondary combustion chamber, a heat exchange area, a desulfurization and denitrification area and a dedusting and demisting area which are separated by separator plates and sequentially communicated with each other. The box body is provided with a smoke inlet and a smoke outlet; the secondary combustion chamber is communicated with a smoke inlet pipeline through the smoke inlet; and the dedusting and demisting area is communicated with the outside of the box body through the smoke outlet. The beneficial effects of the box are that: according to the comprehensive treatment box for waste incineration flue gas, tail gas treatment devices such as the flue gas secondary combustion chamber, a waste heat exchanger, a wet desulfurization and denitrification device and a wet electric dedusting and demisting device are ingeniously arranged in the box body, and waste heat utilization of flue gas and tail gas treatment are highly integrated in one cabinet for completing, so that small integration is achieved, wind resistance is low, materials are saved, and efficiency is high.

Description

technical field [0001] The invention relates to flue gas treatment equipment, in particular to a garbage incineration flue gas comprehensive treatment box. Background technique [0002] Generally, there are two kinds of products in thermal degradation (incineration or pyrolysis) of organic solid waste (such as domestic waste), which are primary flue gas pyrolysis gas and waste residue. The former is an available resource—the carrier of energy, and also the main carrier of environmental pollutants. Therefore, in the process of organic solid waste treatment, how to do a good job in energy utilization and pollutant control of primary flue gas is the top priority. [0003] At present, the common method is to use boilers for heat exchange and utilization. The exhaust gas is treated by conventional desulfurization and denitrification, activated carbon injection, and bag dust removal. It is separated in series, the system has large wind resistance, large investment, and occupies a...

Problems solved by technology

[0003] At present, the common method is to use boilers for heat exchange and utilization. The exhaust gas is treated by conventional desulfurization and denitrification, activated carbon injection, and bag dust removal. Separated in series, the system has large wind resistance, large investment, and occupies a lot of land, so it is not suitable for small integration
