I. equipment composition:
Liquid ring vacuum pump and compressor, gas-liquid separator, heat exchanger, common chassis, internal pipeline
Ii. Working principle
The extracted gas enters the vacuum pump/compressor from the suction port and enters the gas-liquid separator together with part of the working liquid after being compressed by the vacuum pump/compressor. In the separator, the gas-liquid two phases are separated, the gas is discharged from the exhaust port, and the working liquid is inhaled by the vacuum pump/compressor through the heat exchanger for recycling.
Open circulation: the water discharged by the liquid ring vacuum pump enters the large circulation pool or is directly discharged. This water supply and drainage method is convenient and easy to use, and is widely used in practical applications.
Closed cycle: if the extracted medium contains organic solvents, toxic substances and other water discharge caused great pressure on the environment, the extracted organic solvents are not easy to recover and are wasted, more and more chemical and pharmaceutical enterprises have adopted closed cycle system.
