China Composition of VPSA Oxygen Generators

VPSA Oxygen Generators are a complete set of equipment for the production of oxygen (or liquid oxygen), nitrogen (or liquid nitrogen) and argon, neon-helium, krypton-xenon and other mixed gases.

China's development of pressure swing adsorption oxygen technology started earlier, more than 20 years, due to technical dispersion, lack of contact between each other, China's pressure swing adsorption oxygen technology development is slow, with the gap between foreign and growing. The 1970s is China's PSA separation of air oxygen technology development of the heyday of the country has more than a dozen units have carried out the experimental study of pressure swing adsorption oxygen technology, the establishment of a number of sets of industrial test equipment.

VPSA oxygen generators are the use of CPSA dedicated analysis sieve and desiccant mixed bed to selectively adsorb the air nitrogen, carbon dioxide and water impurities, the other oxygen in the bed at the end of accumulation and collection, under vacuum conditions for adsorption saturation State of the molecules to desorption, and thus the cycle of the higher purity of oxygen.

VPSA oxygen generator is composed by the blower, vacuum pump, cooler, adsorption system, oxygen buffer tank, the control system. Blower for the entire system to provide raw air, according to the vacuum pressure swing adsorption oxygen equipment design conditions, combined with the user's use conditions, select the exhaust pressure to meet the design conditions of the blower gas supply. Vacuum pump to ensure the normal analysis of the entire system, the system is in an ideal vacuum state, so that the overall equipment can continue to nitrogen oxygen production. The blower is pressurized to obtain high temperature and high pressure compressed air, and then through the water cooler to the air temperature dropped to the required process operating temperature, into the adsorption tower for adsorption. The adsorption system consists of two adsorbent columns with a zeolite molecular sieve adsorbent and a piping valve. Oxygen buffer tank on the entire equipment to play a regulator role.
