Description

Technical Field

[0001] The utility model relates to the technical field of VPSA oxygen generators, in particular to an outdoor placement rack for a VPSA oxygen generator. Background Art

[0002] VPSA oxygen generator is a device that produces oxygen using the principle of molecular sieve adsorption. VPSA oxygen generator is usually composed of an adsorption tower, a pressure fan, a molecular sieve, a cooler, a regeneration fan and an electrical control system. After the air is pressurized by the pressure fan, it passes through the molecular sieve adsorption tower, and carbon dioxide, water vapor and other impurities are adsorbed on the surface of the molecular sieve, so that oxygen can be enriched. During the adsorption process, the molecular sieve will gradually become saturated, and a regeneration fan is required to regenerate it. The regeneration fan sends dry air into the molecular sieve adsorption tower to release the adsorbed impurities and take away impurities such as water vapor and carbon dioxide. After the regeneration process is over, the molecular sieve returns to the adsorption state and the oxygen production operation can continue.
