Title: Pressure swing cycle system
IPC: B01J20/28
Filed: 1992-03-27
Abstract: PURPOSE:To effectively regenerate a moisture adsorbent and to operate a PSA method with stable performance by providing the moisture adsorbents on both sides of an adsorbent, executing introduction of air and pressure reduction through one moisture adsorbent for a fixed time, discharging the unadsorbed gas through the other moisture adsorbent and then performing the reverse operation. CONSTITUTION:First, in the pressure reducing process of a pressure swing. when voltage is applied to only a two-way valve 7a and an air pump 1 is operated, the 1st moisture adsorbent 4 and a nitrogen adsorbent 6 are evacuated, causing the nitrogen adsorbent 6 to discharge gas rich in nitrogen. At the same time, the nitrogen adsorbent 6 is regenerated and the 1st moisture adsorbent 4 is also regenerated. After the pressure reducing process is finished, the conversion to the pressurizing process takes place and the air is fed to the 1st moisture adsorbent 4. After that, it goes to the nitrogen adsorbent 6 and turns into gas rich in oxygen to be discharged through the 2nd moisture adsorbent. At this time, it is extremely less humid around the 2nd moisture adsorbent 5. Then the nitrogen adsorbent 6 undergoes breakthrough by nitrogen to shift the pressurizing process to the pressure reducing one again.
