Description

TECHNICAL FIELD

[0001] The utility model relates to vacuum unit technical field, concretely is an environmental protection type vacuum unit. BACKGROUND

[0002] The environmental protection type vacuum unit is an environmental protection type water jet vacuum unit, which can efficiently extract the gas in the container through the comprehensive action of the jet principle and the vacuum principle and complete the gas-liquid separation in the water tank. At the same time, since water is used as the working medium in the unit, it also has good cooling and purification effects. This not only reduces the temperature of the unit during operation, but also reduces the emission of harmful gases, thereby achieving environmental protection;

[0003] During the operation of the water jet vacuum unit, when the high-speed water flow is sprayed into the suction chamber, the gas in the suction chamber will be forcibly carried and mixed with it to form a gas-liquid mixed flow. This mixed flow then enters the diffuser, and in the expansion section of the diffuser, the kinetic energy of the mixed jet is converted into pressure energy, the speed is reduced and the pressure is increased. At this time, the gas is further compressed and discharged together with the water. After being discharged outside the pump, the gas-liquid mixture enters a water tank. In the water tank, due to the action of gravity, the gas and water will naturally separate, the gas is released into the atmosphere, and the water is recycled by the centrifugal pump. The entire gas suction-exhaustion-re-suction cycle is completed, and in this cycle, the liquid will adsorb impurities in the gas, thereby causing solid impurities in the mixed fluid to accumulate in the water tank. This is not conducive to the use of circulating liquid, so it needs to be cleaned regularly. CONTENT OF THE UTILITY MODEL
