Low Pressure Cryogenic Oxygen Plant For Medical

Product Description

Process Description

The air passes through the air filter, enters the air compressor, compresses to 0.7mpa in the compressor, and then enters the purifier after cooling, where the impurities such as water, carbon dioxide and acetylene in the air are removed. The purified air enters the heat exchanger for heat exchange with the backflow polluted nitrogen. A part of the gas is pumped into the turbine expander through the outlet of the heat exchanger, and the expansion provides a cooling source for the whole set of devices. The other gases continue to cool through the second heat exchanger and then enter the rectifying tower, where they are separated by oxygen and nitrogen. Finally, qualified liquid nitrogen is obtained from the top of the rectifying tower. After decompression by the throttle valve, the liquid air at the bottom enters the condensing evaporator at the top of the tower and the nitrogen heat exchange at the top of the rectifying tower, and then passes through the cooler, the second heat exchanger and the main heat exchanger cooling box as the regenerative purifier.
