Yakanyanya kuchena nitrogen zvidyarwa zvave kuwedzera kukosha mumaindasitiri akati wandei semakemikari, zvemagetsi, uye zvekurapa zvikumbiro. Nitrogen chinhu chakakosha mune angangoita ese maindasitiri aya, uye kuchena kwayo uye mhando inoita basa rakakosha mukuona kuti chigadzirwa chemhando yepamusoro. Naizvozvo, kugadzira nitrogen yemhando yepamusoro kwakakosha zvakanyanya.
Pressure swing adsorption (PSA) tekinoroji inogona kushandiswa kuchenesa nitrogen nekubvisa okisijeni uye kumwe kusvibiswa. PSA yakavakirwa pamusimboti wegasi adsorption pane yakasimba adsorbent zvinhu. Iyo adsorbent inosarudzwa yakasarudzwa zvichienderana nekugona kwayo kushambadza mamorekuru egasi ekufarira, uku ichibvumira mamwe magasi kupfuura.
Muchirimwa chenitrogen chakanyanya kuchena, tekinoroji yePSA inogona kushandiswa kugadzira nitrogen kana okisijeni nekudzora adsorption uye desorption yemamorekuru egasi. Maitiro acho anosanganisira kudzvanya mhepo kune yakatsanangurwa kudzvanywa uye kuipfuura nepamubhedha we adsorbent zvinhu. Iyo adsorbent zvinhu inoshambadza iyo okisijeni uye kumwe kusvibiswa, nepo nitrogen inopfuura nepamubhedha uye inounganidzwa mutangi rekuchengetedza.
Iyo adsorbent zvinhu inogona kuvandudzwa nekusunungura kudzvanywa, izvo zvinoita kuti mamorekuru egasi abvise kubva pane izvo. Iyo gasi yakasvibiswa inobva yapfuudzwa kunze kwehurongwa, uye adsorbent yakagadzirira kushambadza imwe kutenderera kwemamorekuru egasi.
Imwe yemabhenefiti ekutanga ekushandisa tekinoroji yePSA mukuchena kwakakwira nitrogen zvidyarwa ndiko kudhura kwayo. PSA tekinoroji inoshanda zvakanyanya uye haidi michina yakaoma kana vashandi vane hunyanzvi kuti vashande. Pamusoro pezvo, ine mari yakaderera yekushandisa, sezvo isingade chero kunze kwesimba rekunze kunze kwemhepo yakamanikidzwa.
Chimwe chakanakira kuita kwayo zvakasiyana-siyana. PSA tekinoroji inogona kuburitsa ese nitrogen uye okisijeni, zvichienderana neiyo adsorbent zvinhu zvakasarudzwa. Mhepo ine okisijeni inogona kushandiswa mumaindasitiri akati wandei senge maapplication ekurapa uye welding, umo oksijeni yakakwira inodiwa.
Nekudaro, kugadzira yakakwira kuchena nitrogen kana okisijeni kuburikidza nePSA tekinoroji inoda kunyatsosarudzwa kweiyo adsorbent zvinhu. Iyo adsorbent zvinhu zvinofanirwa kuve nekusarudzika kwakakwirira kwemamorekuru egasi ekufarira uye inofanirwa kuve yakakodzera mamiriro ekushanda eiyo yakanyanya kuchena nitrogen chirimwa. Pamusoro pezvo, saizi uye chimiro cheiyo adsorbent zvinhu zvinofanirwa kuvandudzwa kuti zvideredze kudonha kwekumanikidza uye kuve nechokwadi chekushambadza.
Mukupedzisa, tekinoroji yePSA inzira inoshanda zvakanyanya uye inodhura yekuburitsa yakakwira kuchena nitrogen kana okisijeni mune yakanyanya kuchena nitrogen miti. Inopa mabhenefiti akati wandei, kusanganisira kuita zvakasiyana-siyana uye mutengo wakaderera wekushandisa. Nekudaro, kunyatsosarudzwa kweiyo adsorbent zvinhu kwakakosha kuti uve nechokwadi chekuchena kwaunoda uye mhando yenitrogen kana oxygen inogadzirwa. Nemabhenefiti ayo akawanda, tekinoroji yePSA isarudzo inoyevedza kumaindasitiri anoda mhando yepamusoro, yakavimbika nitrogen yekupihwa.
