Waste incineration flue gas backflow decarburization device

Abstract

The invention discloses a waste incineration flue gas backflow decarburization device, and belongs to the technical field of environmental protection. The decarburization device comprises a compressor, a decarburization machine tank body, an alkali storage tank and a water storage tank, the inlet and the outlet of the compressor are connected with a smoke inlet pipe of which one end is connected with a garbage incinerator, and the other end of the smoke inlet pipe is connected with a smoke outlet pipe communicated with the bottom of the decarburization machine tank body. When a first water pump works, an alkaline solution in the alkali storage box is extracted, and is atomized from an atomizing nozzle along a lower rod to spray alkaline solution mist, so the contact area with flue gas is increased; and after a reaction is finished, a cylinder drives a round disc to move downwards in the decarburization machine tank body, the sealing ring of the round disc is in contact with the inner wall of the decarburization machine tank body, liquid drops adsorbed on the inner wall of the decarburization machine tank body are slowly pushed downwards, the disc descends to reduce the volume of the inner cavity of the decarburization machine tank body, reacted gas and liquid are pumped into the water storage tank in cooperation with a second water pump, and a physical absorption method is adopted to make carbon dioxide absorbed by a gas tank, so residual gas and liquid in the gas tank are absorbed.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a waste incineration flue gas backflow decarbonization device. Background technique [0002] Waste incineration flue gas has attracted great attention as a renewable and clean energy with high calorific value. my country's waste incineration flue gas resource reserves are very rich and the market demand is huge. Domestic waste incineration flue gas is currently mainly used as fuel for rural stoves, and its use value is low. The development of waste incineration flue gas at home and abroad shows that waste incineration flue gas power generation is an important means of efficiently utilizing waste incineration flue gas. The decarbonization method in waste incineration flue gas is mainly liquid absorption method, and liquid absorption method is divided into physical absorption method and chemical absorption method. Most of the existing decarbonization devices do n...

AI Technical Summary

Problems solved by technology

Most of the existing decarbonization devices do not have the ability to use physical absorption and chemical absorption at the same time, so that the decarbonization effect of waste incineration flue gas is not good, and there will be a lot of impurities after decarbonization
