Abstract

A waste water cyclone system for a desulfuration device of a thermal power station comprises a gypsum cyclone station underflow collecting box, a gypsum cyclone feeding collecting box, a gypsum cyclone station overflow collecting box, a waste water cyclone pump, a waste water cyclone station and a waste water collecting box, wherein a waste water cyclone pump suction inlet and a waste water cyclone pump return port are formed on the gypsum cyclone station overflow collecting box; the waste water cyclone pump suction inlet is communicated with the inlet of the waste water cyclone pump through a cyclone pump liquid feeding pipe; and the waste water cyclone pump return port is communicated with a cyclone pump liquid outlet pipeline through a liquid return pipe. According to the waste water cyclone system which is simplified, a waste water cyclone box and some related equipment thereof are avoided, the initial investment of wet flue gas desulfurization device is reduced, the system configuration is simpler, operation fault points are reduced, and the running cost of the desulfuration is lowered.

Description

technical field [0001] The invention relates to a waste water cyclone system arranged in a desulfurization device of a thermal power plant. Background technique [0002] In the flue gas desulfurization process of thermal power plants, the gypsum slurry in the desulfurization device will be enriched with impurities such as heavy metal elements, fine dust and chloride ions during the continuous circulation process. These impurities will accelerate the corrosion of the desulfurization device on the one hand, and on the other On the one hand, it will affect the quality of gypsum, and it will also affect the desulfurization efficiency of the desulfurization device. Therefore, the desulfurization device needs to discharge a certain amount of wastewater to reduce the content of these impurities in the gypsum slurry. [0003] Existing desulfurization devices discharge waste water by using a waste water cyclone system, see figure 1 The specific method is that the gypsum slurry disch...
