Abstract

The invention provides a coal-fired furnace waste gas absorption and purification device, which includes a dust removal unit, an oxidation unit and an adsorption unit. The inner wall of the unit is symmetrically provided with baffles parallel to each other; the dust removal unit communicates with the oxidation unit through the first connecting pipe, and the oxidation unit is provided with a first helical blade wound on a fixed shaft in a spiral shape. The first helical blade and the side wall of the oxidation unit form a first helical airflow channel, the outer periphery of the first helical blade is provided with a nano-titanium dioxide coating, and the side wall of the oxidation unit is provided with an ultraviolet lamp; The unit is connected with an adsorption unit through the second connecting pipe, and the adsorption unit is an alkali liquor adsorption unit. The invention effectively reduces the concentration of the acid pollutants and improves the environmental quality by filtering, oxidizing and adsorbing the gas pollutants discharged from the coal mining furnace.

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...
