Kushanda kweCarbon Molecular Sieve muKuchengetedzwa Kwekudya

    Ikozvino nitrogen yanyanya uye zvakanyanya kushandiswa mukuchengetedza chikafu, nekuti nitrogen chinhu chisina basa zvakanyanya, Pasi peyakajairika tembiricha uye kumanikidza, zvinhu zvakawanda hazviite nazvo. Uchishandisa nitrogen kupatsanura okisijeni kugadzirisa mamiriro aripo echikafu kunogona kudzikisira oxidation uye kumisa metabolism uye kufema kwechikafu. Panguva imwecheteyo, akawanda ma microorganisms anorasikirwa nharaunda yavo yekugara.

    Pane nzira nhatu dziripo dzekugadzira nitrogen, dzinoti, cryogenic mweya kupatsanura, mamorekuru sieve mweya kupatsanurwa uye membrane mweya kupatsanurwa. Iyo cryogenic yemhepo yekuparadzanisa chirimwa yakakodzera kune yakakura-yakakura maindasitiri kugadzirwa kweitrogen, ine michina yakaoma, yakakura pasi nzvimbo, yakakwira capital kuvaka mutengo, hombe kamwe-nguva kudyara, yakakwira kushanda mutengo uye kunonoka kugadzira gasi. Kunyangwe membrane yekuparadzaniswa kwemhepo yakakodzera kune vashoma uye vepakati-saizi senitrogen vashandisi, yakafanana nesosi mamoresi eiyo imwechete yakatarwa Mutengo wemidziyo yemhepo yekuparadzanisa nzira inodarika gumi neshanu muzana muzana kupfuura iyo yemolecular sieve mweya yekuparadzanisa nzira. Maitiro kuyerera kwema molecular sieve mweya yekuparadzanisa nzira iri nyore, iyo degree of kushandisa michina yakakwira, iyo gasi inogadzira inokurumidza, uye simba rekushandisa rakaderera. Kechipiri, kuchena kwe nitrogen kunogona kugadziridzwa zvinoenderana nezvinodiwa nevashandisi munzvimbo yakakura, ine mashandiro akanaka uye kugadzirisa, yakaderera mashandiro emutengo, uye kugona kwakasimba kwechigadzirwa.

    Parizvino, kugadzirwa kwe nitrogen nekumanikidza swing adsorption (PSA) ye kabhoni samolecular nesefa yakavakirwa pane yakachena yakatsindirwa mweya senge mbishi zvinhu uye kabhoni mamorekuru sieve se adsorbent. Nheyo yePSA inoshandiswa kugadzira iyo kabhoni samolecular nesefa izere nema micropores anosarudza kushambadza magasi mamorekuru kuwana nitrogen. Mushure mokunge mamorekuru sieve adsorption azara, mamorekuru eoksijeni ari mumakomba echeki yemolekyuli anoda kuburitswa kuitira rinotevera basa. Kana mamorekuru eoksijeni aburitswa, iyo kabhoni inozoburitswa Iko kumanikidza kwema molecular sieve layer kunoderedzwa kubva pa0.3-0.6mpa kuenda kune yakajairwa kumanikidza mushure mekumanikidzwa kuenzana. Iko kusarudzika kumanikidzwa kweoxygen mugomba re carbon molecular sieve yakakura kudarika iya yekunze oxygen. Okisijeni inoyerera ichienda kunze ichibva mugomba, uye mamorekuru eakisijeni akaburitswa anoburitswa kubva mugomba resefu yemolekyuli.

    Kunyangwe iyo iripo nitrogen yekugadzira sisitimu inogona kupa nitrogen mamiriro ekuchengetedza chikafu, kana yakamanikidzwa mweya ichipinda mushambadziro yeshorosi ine kabhoni mamorekuru sieve kugoverwa, iyo yekuyerera kwemhepo inokanganisa kumhanya kwakanyanya uye kugovera hakuna kuenzana. Carbon mamorekuru nesefa iri nyore kurova kana kutsemura, izvo zvinoita kuti adsorption mhedzisiro iwedzere kuipa, kushambadza kunyatso hakusi kwakakwirira, hupenyu hwebasa rekabhoni mamoreji sieve yakafupiswa, uye kuchena kwe nitrogen inogadzirwa inoshungurudzwawo, ndiyo inonyanya zvakakosha Zvakakosha kushandisa nitrogen yekuchengetedza chikafu, izvo zvakasiyana neindasitiri. Inoda imwe yakachena nitrogen kuchengetedza chikafu kubva kune anaerobic bacteria uye kusvibiswa kweguruva.

    Naizvozvo, zvinodikanwa kukudziridza kumanikidza swing adsorption (PSA) kabhoni mamorekuru sieve senitrogen system yekuchengetedza chikafu, iyo inogona kupa yakachena nitrogen uye kuwedzeredza hupenyu hwehupenyu hwecarbon molecular sieve.
