Vacuum pollution discharge device capable of automatically separating gas, liquid and pollutants in gas and liquid

The utility model discloses a vacuum blowdown device capable of automatically separating gas, liquid and pollutants in the gas and the liquid, which comprises a flashboard control box, a cyclone separator, a sealed blowdown water tank and a vacuum fan, and the sealed blowdown water tank is positioned below the cyclone separator. According to the device, a plurality of input pipelines are controlled through the flashboard box, so that a gas-liquid mixture at any input port enters the cyclone separator at the lowest inlet, and the cyclone separator is combined with the vacuum fan to generate high vacuum for high-speed gas-liquid separation; liquid and pollutants (such as stickers) and gas contained in the liquid can be effectively separated at the fastest speed and rapidly flow into the sealed water tank, and the problem that the pollutants (the stickers or other impurities) in the liquid are easily dehydrated, solidified and condensed on the inner wall of the separator in the treatment process is solved. 本实用新型
