VPSA PSA oxygen machine

pressure swing adsorption molecular sieve is a molecular sieve having a function of a mixed gas of selective adsorption, the adsorption capacity with temperature and pressure changes. Typically oxygen Pressure swing adsorption technology air separation unit adsorption bed must contain two steps; adsorption and resolution. In order to obtain a continuous product gas, usually oxygen apparatus are means more than two adsorbent beds, and from the perspective of energy and stability, in addition to setting the necessary additional steps. Usually go through each bed adsorption, release the pressure, evacuation or decompression regeneration, replacement and rinse the equalizing boost other steps, periodically repeat the operation. At the same time, each adsorbent bed, respectively, at different steps, time switch under PLC control, so that the bed several coordinated operations on the pace of practice is staggered, so that the pressure swing adsorption system can run smoothly, continuous access to the product gas .
