Abstract

The invention provides a coal-fired boiler exhaust gas absorption and purification device. The device comprises a dust removal unit, an oxidation unit and an adsorption unit. The dust removal unit includes a first exhaust gas inlet and a first exhaust gas outlet separately disposed at the bottom and the top of the dust removal unit. The opposite inner sides of the inner wall of the dust removal unit are symmetrically provided with mutually parallel baffle plates. The dust removal unit communicates with the oxidation unit through a first connection pipe, the oxidation unit is internally provided with a first spiral blade spirally wound on a fixed shaft, and the first spiral blade and the side wall of the oxidation unit form a first spiral airflow passage, the periphery of the first spiral blade is provided with a nanometer titanium dioxide coating, and the side wall of the oxidation unit is provided with a UV lamp. The oxidation unit communicates with the adsorption unit through a second connecting pipe, and the adsorption unit is an alkaline adsorption unit. The device filters, oxidizes and adsorbs gaseous pollutants discharged from a coal mining furnace, effectively reduces the concentration of acidic pollutants and improves the environmental quality.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a coal-burning furnace exhaust gas absorption and purification device. Background technique [0002] Coal-fired heating boiler is the most commonly used boiler, which has the advantages of economy and benefits. For urban-rural fringe areas and vast rural areas without central heating and gas heating conditions, coal-fired heating boilers with lower heating costs is ideal. However, the heat generated by combustion in the existing heating furnace cannot be efficiently converted with the surrounding space, and is directly discharged from the furnace, which reduces the efficiency of heat energy utilization and causes waste of resources; Pollutants such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds and smoke will also be formed. Among them, carbon dioxide, sulfur dioxide, and nitrogen oxides are all acidic oxides. The acidic substan...
