What is the function and working principle of desulfurization vacuum pump?

The function of desulfurization vacuum pump is used in gypsum dehydration system. The working principle is the water ring vacuum pump used in the desulfurization process of power plant, and a proper amount of water is filled in the pump body as the working fluid. According to the query, it is easy to display the water pump network.

1. Desulfurization vacuum pump is a kind of pump that continuously sucks and discharges gas, thus achieving the purpose of pumping air. Desulfurization vacuum pump is mainly used in gypsum dehydration system, which removes the water in gypsum slurry by vacuumizing and turns gypsum slurry into gypsum. The inlet of the vacuum pump is the suction port, which is mainly used for pumping air, and the outlet is the exhaust port, which is mainly used for exhausting the inhaled gas. The gas discharged from the exhaust port of desulfurization vacuum pump has a high humidity, and the exhaust port is generally located in the north outdoor. In order to prevent condensate from flowing back to the exhaust port of the pump body, the direction is downward.

2. The working principle of desulfurization vacuum pump. During the working process of water ring vacuum pump used in desulfurization process of power plant, the pump body is filled with appropriate amount of water as working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring with roughly the same thickness according to the shape of the pump cavity. The lower inner surface of the water ring is just tangent to the impeller hub, and the upper inner surface of the water ring is just in contact with the tip of the blade (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, which is divided into several small cavities with the same number of blades by the impeller. If the lower part of the impeller is 0℃ as the starting point, the volume of the small cavity changes from small to large before the impeller rotates 180℃, which is communicated with the suction port on the end face. At this time, the gas is inhaled, and when the inhalation ends, the small cavity is isolated from the suction port. When the impeller continues to rotate, the small cavity changes from large to small, so that the gas is compressed. When the small cavity communicates with the exhaust port, the gas is exhausted from the pump.
