The flue gas enters the wet absorption tower of the desulfurization unit and comes into contact with the top-down sprayed limestone slurry droplets counter-currently, in which the acidic oxides SO2 and other pollutants HCL and HF are absorbed, and the flue gas is fully purified and discharged after demisting; the slurry reaction after absorbing sulfur dioxide generates CaSO3, which generates CaSO4.2H2O through in-situ forced oxidation and crystallization, and is dehydrated to obtain After dehydration, gypsum is obtained, and the comprehensive treatment of sulfur-containing flue gas is finally realized.
Wet electrostatic precipitator, electrostatic precipitator that uses water spray or overflow water to form a water film on the surface of the dust collection pole to achieve pole plate cleaning. Wet dust removal can avoid the re-fluttering of settled dust and achieve high dust removal efficiency. The operation is more stable because there is no vibrating device, but there are problems of corrosion, sludge and sewage disposal. Application is not as wide as dry electrostatic precipitator.
UV photolysis air purifier is the use of special high-energy high ozone UV light beam irradiation of malodorous gases, without adding any substances. Only need to set the corresponding exhaust pipeline and exhaust power, so that the odor gas through the equipment for deodorization decomposition purification, without adding any substances involved in the chemical reaction. Deodorization efficiency can reach up to 99% or more, and the deodorization effect greatly exceeds the national emission standards for odor pollutants promulgated in 1993 (GB14554-93).
Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in exhaust gases at a lower temperature. Therefore, catalytic combustion is also known as catalytic chemical conversion. As the catalyst accelerates the course of oxidation and decomposition, most hydrocarbons can be oxidized completely by catalyst at a temperature of 300~450℃.
Compared with thermal combustion method, catalytic combustion requires less auxiliary fuel, lower energy consumption and smaller size of equipment and facilities. However, the promotion and application of this method in industrial processes is hampered by problems such as poisoning of the catalyst used, replacement of the catalytic bed and high cleaning costs.
Foshan Yiqing Environmental Engineering Technology Co., Ltd. is a local manufacturer of mine dust collector and wet type electric dust collector in Guangdong, which mainly deals with all kinds of dust collectors and brick factory desulfurization tower products.
