Application:
The DS series desulfurization circulating pump is mainly applied to the flue gas desulfurization system in power plant, which is the slurry washing circulating pump of absorption tower of the most widely used limestone-gypsum method of FGD wet desulfurization process currently in the world.
Feature:
The flue gas desulfurization (FGD) after combustion in power plant accounts for more than 98% of the total quantity, while that of the limestone-gypsum desulfurization process is about 85%, which is of high efficiency and most wide application. The temperature of original flue gas from the boiler during desulfurization process of the flue gas desulfurization system in steam power plant is higher (150-180C), which is lowered by the gas-gas heat exchanger (GGH). The original flue gas then shall be transported to the absorption tower, which shall flow from upper to down to carry out the counter-flow contact reaction with the limestone-gypsum mixed slurry jetted from the upper party of the absorption tower to accomplish the absorption of SO2. The clean flue gas after absorption shall be heated up by through the demister and gas-gas heat exchanger (GGH), which then shall be discharged to atmosphere from chimney. Detailed procedures refer to the following diagram.
