High Purity And Low Pressure Of PSA Oxygen Generator With Continuous Cycle Operation

High Purity And Low Pressure Of PSA Oxygen Generator , Which Can Be Fully Automated With Continuous Cycle Operation

Working Principle Description:

PSA oxygen production equipment is a new gas separation technology. Taking adsorbent molecular sieve as an example, its principle is to separate the gas mixture by using the difference of "adsorption" performance of molecular sieve for different gas molecules. Using air as raw material, nitrogen and oxygen in the air were separated by a high-efficiency and selective solid adsorbent. Zeolite molecular sieves selectively adsorb molecules according to the size of pores in their crystals, that is, adsorb molecules of a certain size and repel molecules of larger substances. In this way, oxygen rich components can be obtained in the gas phase.

After a period of time, the adsorption of nitrogen on zeolite reaches equilibrium. According to the different adsorption capacity of zeolite under different pressures, reducing the pressure makes zeolite release the adsorption of nitrogen. This process is called regeneration. Pressure swing adsorption (PSA) usually uses two parallel towers to alternately perform pressure adsorption and decompression regeneration, so as to obtain continuous oxygen flow.
