Nitrogen kugadzira molecular sieve

Mundima yeindasitiri, jenareta renitrogen rinoshandiswa zvakanyanya mu petrochemical, gasi rechisikigo liquefaction, simbi, chikafu, mishonga uye zvemagetsi indasitiri. Iyo nitrogen zvigadzirwa zve nitrogen jenareta zvinogona kushandiswa sechiridzwa gasi, asiwo semaindasitiri mbishi zvinhu uye refrigerant, inova inodiwa yeruzhinji michina mukugadzirwa kwemaindasitiri. Iyo nitrogen jenareta inonyanya kukamurwa kuita marudzi matatu: yakadzika inotonhora mhepo yekuparadzanisa nzira, membrane yekuparadzanisa nzira uye molecular sieve pressure shanduko adsorption nzira (PSA).
Yakadzika inotonhora mhepo yekuparadzanisa nzira ndeye kushandisa iyo yakasiyana yekubikira poindi yeokisijeni uye nitrogen mumhepo, uye kugadzirwa kwemvura nitrogen uye mvura okisijeni kuburikidza nemusimboti wekumanikidza, firiji uye yakaderera tembiricha distillation ". Iyi nzira inogona kuburitsa yakaderera tembiricha mvura nitrogen uye mvura okisijeni, hombe kugadzirwa chiyero; iyo yakashata ikudyara kukuru, kunowanzo shandiswa munitrogen uye oxygen kudiwa mumetallurgy uye makemikari indasitiri.
Membrane separation method imhepo seyakabikwa, pasi pemamwe mamiriro ekumanikidzika, uchishandisa okisijeni nenitrogen mu membrane ine mwero wakasiyana wepermeability kugadzira oxygen nenitrogen kupatsanurwa?. Iyi nzira ine zvakanakira chimiro chakareruka, hapana switching valve, vhoriyamu diki, nezvimwewo, asi nekuti iyo membrane zvinhu zvinonyanya kuenderana nekunze, mutengo wazvino unodhura uye mwero wekupinda wakaderera, saka unonyanya kushandiswa kune zvakakosha kuyerera kudiki, senge mobile nitrogen kugadzira muchina.
Molecular sieve pressure adsorption method (PSA) imhepo seyakabikwa, carbon molecular sieve as adsorbent, kushandiswa kwepressure adsorption principle, kushandiswa kwecarbon molecular sieve for oxygen and nitrogen adsorption and oxygen and nitrogen separation method “. Iyi nzira ine hunhu hwekuyerera kwakapfava, dhigirii rekuita otomatiki, kushandiswa kwesimba shoma uye kuchena kwenitrogen, uye ndiyo inonyanya kushandiswa tekinoroji. Mhepo isati yapinda mushongwe yemunhu, mvura iri mumhepo inofanirwa kuomeswa kuti ideredze kukukurwa kwemvura pa molecular sieve uye kuwedzera hupenyu hwesevhisi ye molecular sieve. Mune yakajairwa PSA nitrogen kugadzirwa maitiro, iyo yakaoma shongwe inowanzoshandiswa kubvisa mwando mumhepo. Kana shongwe yekuomesa yakazadzwa nemvura, shongwe yekuomesa inopeperetswa kumashure nemhepo yakaoma kuti ione kuvandudzwa kweshongwe yekuomesa.
