Small Liquid Nitrogen Generator

 

Cryogenic air separation equipment can be used in many fields such as chemical industry, new energy, metallurgy, etc., and is required for industrial production that requires a large amount of high-purity nitrogen. The cryogenic air separation unit uses low-temperature condensation to convert air into a liquid state. Because different gases have different evaporation temperatures, they can be separated and purified from the air, and a large amount of high-purity nitrogen, oxygen and other gases required by industry can be obtained.

 

 

It is composed of air precooling system (air cooling system) and molecular sieve purification system (purification system). The compressed raw air has a higher temperature, and the air pre-cooling system reduces the temperature of the air through contact heat exchange, and at the same time, it can wash harmful impurities such as acidic substances in it. The molecular sieve purification system further removes moisture, carbon dioxide, ethylene fast, propylene, propane, heavy hydrocarbons and nitrous oxide in the air, which are harmful to the operation of air separation equipment.
