High-temperature Type Desulfurization Pump

Desulfurization pumps are widely used in the following fields:

• Wet Desulfurization Systems in Thermal Power Plants: Thermal power plants are one of the most widespread applications of desulfurization pumps. In wet desulfurization systems, the desulfurization pump is primarily responsible for mixing flue gas containing sulfur dioxide with a desulfurizing agent (such as limestone slurry) to form a desulfurization slurry. This slurry is then continuously circulated to the absorption tower by a circulating pump, ensuring full contact with the flue gas to complete the desulfurization reaction. During this process, the desulfurization pump must withstand high concentrations of highly corrosive limestone slurry and potential particulate abrasion.
• Sintering Flue Gas Desulfurization in the Steel Industry: The sintering process in the steel industry generates a large amount of flue gas containing pollutants such as sulfur dioxide and dust. To meet environmental protection requirements, this flue gas needs to undergo desulfurization treatment. Under these operating conditions, desulfurization pumps not only need to handle high-concentration desulfurizing agent solutions but also need to cope with solid particulate matter entrained in the flue gas, which places higher demands on the pump's wear resistance.
• Chemical Industry Waste Gas Treatment: Chemical enterprises generate various sulfur-containing waste gases during production processes, such as sulfuric acid production waste gas and coke oven gas from coking plants. The desulfurization treatment of these waste gases also relies on desulfurization pumps. Unlike thermal power generation and the steel industry, the waste gas composition in the chemical industry is more complex, potentially containing various corrosive gases and particulate matter, posing a more severe challenge to the material selection and design of desulfurization pumps.
