[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. A vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space. Vacuum pumps can basically be divided into two types, gas capture pumps and gas transmission pumps, which are widely used in metallurgy, chemical industry, food, electronic coating and other industries. Common vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, sliding valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. The function of a vacuum pump is to remove gas molecules from the container to reduce the gas pressure in the container to achieve the required vacuum degree.

[0003] At present, the wet flue gas desulfurization gypsum filtration system operates under different working conditions, which leads to water in the vacuum pump exhaust pipe. Since the filtrate water in the water discharged by the vacuum pump contains chloride ions and other heavy metal elements, it is discharged to the ground outside the factory through the exhaust pipe, which will corrode the cement floor and affect the surrounding environment. In winter, it will cause the ground to freeze, which will cause serious hidden dangers to the traffic of vehicles and the safety of people walking. After the ice is cleaned, it will reappear, and the workload of the processing process is large. Therefore, it is necessary to provide a vacuum pump exhaust pipe water recovery device to solve the above technical problems. Utility Model Content
