Usati wanzwisisa nheyo yekushanda uye maitiro ePSA okisijeni jenareta, tinoda kuziva tekinoroji yePSA inoshandiswa nejenareta reokisijeni. PSA (Pressure Swing Adsorption) tekinoroji inowanzoshandiswa kuparadzanisa gasi uye kuchenesa. Iyo PSA pressure swing adsorptionokisijeni jenaretainoshandisa musimboti uyu kubudisa okisijeni yakakwirira-yakachena.
Nheyo yekushanda yeNUZHUOPSA okisijeni jenaretainogona kukamurwa zvakaenzana mumatanho anotevera:
- Adsorption: Chekutanga, mhepo inopfuura nepa pretreatment system kubvisa mhute yemvura uye tsvina. Mhepo yakamanikidzwa inobva yapinda mushongwe yeadsorption, iyo izere neadsorbent ine yakakwira adsorption kugona, kazhinji sero remamorekuru kana activated kabhoni.
- Kuparadzana: Muchishongo che adsorption, zvikamu zvegasi zvinoparadzaniswa maererano nekubatana kwavo pane adsorbent. Okisijeni mamorekuru anonyanya kudsorbed nekuda kwehukuru hwawo hudiki hwemamorekuru uye kushamwaridzana nema adsorbents, nepo mamwe magasi akadai senitrogen uye mhute yemvura yakaoma kushambadza.
- Kumwe kushanda kweiyo adsorption shongwe: Kana adsorption shongwe yakazadzwa uye ichida kuvandudzwa, sisitimu inongochinja ichienda kune imwe adsorption tower yebasa. Uku kuchinjisa kushanda kunovimbisa kuenderera mberi kwekugadzirwa kweokisijeni.
- Regeneration: Iyo adsorption tower inoda kuvandudzwa mushure mekuzara, kazhinji nekudzikisa kudzvanywa kuti uzive. Decompression inoderedza kudzvanywa pane adsorbent, iyo inoburitsa adsorbed gasi uye inodzosera iyo adsorbent kune iyo inogona kushandiswa zvakare. Iyo inoburitsa gasi inobuda kazhinji inodzingwa kubva muhurongwa kuti ive nechokwadi chekuchena.
- Muunganidzwa weokisijeni: Iyo yakagadziridzwa adsorption shongwe inoshandiswa zvakare kutora okisijeni mumhepo, uye imwe adsorption shongwe inotanga kutora okisijeni mumhepo. Nenzira iyi, iyo sisitimu inokwanisa kuramba ichiburitsa yakanyanya kuchena oksijeni.
