KDN-300Y type liquid oxygen generation plant adopts the principle of cryogenic air separation, and adopts the air fraction nitrogen production process with molecular sieve purification at room temperature, pressurized air expansion refrigeration, and low temperature freezer refrigeration.
Complete set of liquid oxygen generation plant supercharged air turbine expander, simple structure, easy operation and maintenance, no pollution, the adiabatic efficiency of the expander can reach more than 80%.
The host-refrigeration compressor in the precooling unit is selected from the well-known brand cold compressor, which has the advantages of silent operation, power saving, long life and high refrigeration efficiency, and fully ensures the safe operation of the refrigeration compressor.
The air separation equipment adopts the nitrogen separation process of single column distillation and positive air expansion refrigeration. The internal parts of the fractionation column are all aluminum structure, that is, aluminum plate-fin heat exchanger, condensing evaporator and distillation column are adopted. The equipment is of good quality and reliable operation.
