Midziyo yekugadzira Nitrogen inowanikwa nekuparadzanisa mweya nenitrogen kubva kune mbishi uchishandisa mhepo seyakagadzirwa.
Kune marudzi matatu emaindasitiri nitrogen:
◆Cryogenic air separation nitrogen
Cryogenic air separation nitrogen inzira yekugadzira nitrogen yave mumakumi emakore apfuura.Inoshandisa mweya sechinhu chakabikwa, inomanikidzwa, inocheneswa, uye yobva yashandisa kupisa kuchinjanisa kunyungudutsa mweya mumhepo yemvura.Mhepo yemvura inonyanya musanganiswa weokisijeni yemvura uye nitrogen yemvura, iyo ine mapoinzi akasiyana emvura okisijeni uye mvura nitrogen (iyo yekubikira yekutanga ndeye -183 ° C pa1 atm, uye yekupedzisira -196 ° C) , uye distillation kuburikidza nemhepo yemvura Zviparadzanise kuti vawane nitrogen.Iyo cryogenic mhepo yekuparadzanisa nitrogen michina yekugadzira yakaoma, inovhara nzvimbo yakakura, ine mari yakakwira mari, uye ine mari hombe mumidziyo, mutengo wekushandisa, wakaderera gasi kugadzirwa (12 kusvika 24 maawa), yakakwirira yekuisa zvinodiwa uye kureba kutenderera.Comprehensive midziyo, kugadzwa uye zvivakwa zvinhu, midziyo iri pazasi 3500Nm3 / h, saizi yekudyara yePSA midziyo yezvakatsanangurwa zvakafanana ndeye 20% ~ 50% yakaderera pane cryogenic air separation unit.Iyo cryogenic air separation nitrogen chirimwa chakakodzera kugadzirwa kwakakura kwemaindasitiri nitrogen, nepo kugadzirwa kwepakati uye kudiki kwenitrogen hakuna hupfumi.
◆Molecular sieve nitrogen
Nzira inoshandiswa nemhepo sechinhu chakabikwa, kabhoni molecular sieve inoshandiswa se adsorbent, kushandiswa kwepressing swing adsorption musimboti, uye sarudzo yakasarudzika yeokisijeni nenitrogen nekabhoni molecular sieve inoshandiswa kupatsanura nitrogen neokisijeni. inowanzonzi PSA nitrogen kugadzirwa.Iyi nzira ndiyo tekinoroji nyowani inogadzira nitrogen iyo yakakurumidza kuvandudzwa muma1970s.Kuenzaniswa neyechinyakare nzira yekugadzira nitrogen, ine maitiro akareruka, yakakwirira dhigirii yeautomation, kukurumidza kugadzirwa kwegasi (15 kusvika 30 maminetsi), kuderera kwesimba rekushandisa, kuchena kwechigadzirwa kunogona kugadziridzwa zvinoenderana nezvinodiwa nemushandisi mune yakakura, nyore kushanda uye kugadzirisa. , kushanda Mutengo wakaderera uye kuchinjika kwakasimba kwechigadzirwa, saka inokwikwidza mumidziyo yekugadzira nitrogen iri pasi pe1000Nm3/h.Inonyanya kufarirwa pakati pevashandisi vadiki uye vepakati nitrogen.PSA nitrogen yave sarudzo yekutanga yevashandisi vepakati nediki nitrogen.nzira.
◆Membrane air separation nitrogen
Mhepo inoshandiswa seyakagadzirwa, uye pasi pemamiriro akasiyana ekumanikidza, magasi ezvivakwa zvakasiyana zvakaita seokisijeni nenitrogen ane mwero wakasiyana wekupinda mu membrane kuparadzanisa okisijeni nenitrogen.Kuenzaniswa nemimwe michina yekugadzira nitrogen, ine zvakanakira chimiro chakareruka, vhoriyamu diki, hapana switching valve, kushomeka kwekugadzirisa, kukurumidza kugadzirwa kwegasi (≤3 maminetsi), nyore kuwedzera kugona, nezvimwe. Inonyanya kukodzera nitrogen kuchena ≤ 98 % yevashandisi vepakati nediki nitrogen vane yakanakisa mutengo / kuita reshiyo.Kana kuchena kwenitrogen kuri pamusoro pe98%, inodarika 15% yakakwira pane PSA nitrogen-kugadzira michina yemhando imwechete.
