What is the working principle of home oxygen concentrator?

The principle of oxygen generator is to utilize the air separation technology, firstly to compress the air with high density and then to utilize the difference of condensation point of each component in the air to make the gas-liquid detachment under a certain temperature, and then further distillation and obtain. Oxygen is generally obtained through this physical method, large-scale air separation equipment is generally designed to allow oxygen ＼ nitrogen and other gases in the process of climbing and descending to fully replace the temperature, to be distilled. The working principle of home oxygen concentrator: the use of molecular sieve physical adsorption and desorption technology. Oxygen concentrator is filled with molecular sieve, which can adsorb nitrogen in the air when it is pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. Molecular sieve in the decompression of the adsorbed nitrogen discharged back into the ambient air, in the next pressurization can be adsorbed nitrogen and oxygen production, the whole process for the periodic dynamic cycle process, the molecular sieve does not consume.
