Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas purification technology, and in particular to a high-efficiency device for removing fine particulate matter from industrial boiler exhaust gas. Background Technology
[0002] Industrial boilers commonly use fuels containing large amounts of minerals and impurities. Coal naturally contains ash, and during combustion, organic matter is oxidized, leaving the ash in solid form. Some fine particles are carried out of the boiler by the flue gas. Biomass contains alkali metals such as potassium and sodium, which easily form molten particles during combustion and ultrafine particles after cooling. Heavy oil contains elements such as sulfur, vanadium, and nickel, which may generate fine metal oxide particles after combustion. If these fine particles are not removed and are released into the air, they will seriously threaten human health, damage the ecological and environmental quality, affect the balance of the climate system, and impair production equipment and energy efficiency. Therefore, it is necessary to remove these fine particles. However, the exhaust gas generated from industrial boilers is at a high temperature, and direct entry into the fine particulate matter removal device may damage the device and affect its service life. Therefore, it is necessary to propose a high-efficiency fine particulate matter removal device for industrial boiler exhaust gas. Utility Model Content
