Mudziyo unoshandisa nzira dzemuviri kupatsanura okisijeni mumhepo kuti uwane nitrogen unonzi jenareta renitrogen.Kune marudzi matatu makuru e nitrogen jenareta, anoti cryogenic air separation, molecular sieve air separation (PSA) uye membrane air separation Law.Nhasi, mugadziri we nitrogen jenareta-HangZhou Sihope tekinoroji co., Ltd.ichataura muchidimbu nezve musimboti uye zvakanakira zvekumanikidza swing adsorption oxygen chizvarwa.
pressure swing adsorption method, inova nzira yePSA, ndeyekushambadza padanho repamusoro kuti uwane kupatsanurwa kwegasi, uye kuwana kuvandudzwa kweiyo adsorbent pane yakaderera dzvinyiriro.Iyi nzira yakavakirwa pane molecular sieve adsorption yeokisijeni uye nitrogen zvikamu mumhepo kuparadzanisa mhepo kuti iwane oxygen.Kana mhepo ikamanikidzwa uye ichipfuura nepakati peiyo adsorption shongwe yakashongedzerwa nemasefa mamorekuru, mamorekuru enitrogen anonyanya kushambadzwa, uye mamorekuru eokisijeni anoramba ari muchikamu chegasi uye ova oxygen.Kana iyo adsorption ichisvika pakuenzana, mamorekuru enitrogen adsorbed pamusoro peiyo molecular sieve anoburitswa kunze nekudzikisira kudzvinyirira kana vacuum, uye iyo adsorption kugona kweiyo molecular sieve inodzoreredzwa.Kuti urambe uchipa okisijeni, mudziyo unowanzo uine maviri kana anopfuura adsorption shongwe, imwe shongwe adsorbs oxygen uye imwe shongwe desorbs, kuitira kuzadzisa chinangwa chekuenderera mberi kwekugadzirwa kweokisijeni.
Iyo PSA nzira inogona kuburitsa okisijeni nekuchena kwe80% -95%.Simba rekushandisa pakugadzira okisijeni rinowanzoita 0.32kWh/Nm3～0.37kWh/Nm3, uye adsorption pressure yakakwira kupfuura mhepo yemuchadenga, kazhinji 30kPa～100kPa.Maitiro acho ari nyore, kushanda pakamuri tembiricha, uye nhanho yeautomation Yakakwirira, inogona kuona isina kurongwa manejimendi, kunyanya chengetedzo yakanaka.Mune vacuum desorption process, kudzvanywa kwechishandiso kwakadzikira, uye mudziyo haudzorerwe nekumisikidzwa kwemidziyo yekumanikidza.Zvinoenderana nehuwandu hwevashambadziri, iyo pressure swing adsorption process yakakamurwa kuita imwe-shongwe process, maviri-shongwe process, matatu-shongwe process, uye shanu-shongwe process.Iyo shanu-shongwe process pressure swing adsorption nzira ndiyo inonyanya kushandiswa, inoshandisa 5 adsorption mibhedha, 4 blowers uye 2 vacuum pombi kuchengetedza 2 mibhedha mu adsorption uye vacuum panguva yese kutenderera, iyo inogadzirisa hunyanzvi dambudziko rehombe-mwero oxygen. production.
Pressure swing adsorption okisijeni yekugadzira maitiro ine zvinotevera zvakanakira: Chekutanga, inotora otomatiki yekuchaja tekinoroji yemuchadenga inlet pressure musiyano kudzikisa huwandu hwemhepo yekuvhuvhuta, kurebesa hupenyu hwesevhisi yemidziyo, uye kuderedza mutengo wekugadzira okisijeni.Yechipiri ndiyo midziyo yakapfava, midziyo mikuru Roots blower uye vacuum pombi yakagadzikana uye yakavimbika, uye hupenyu hwebasa hwema molecular sieve anopfuura makore gumi pasina kugadzirisa.Chechitatu ndechekuti huwandu uye kuchena kweokisijeni inogadzirwa inogona kugadziriswa maererano nekushandiswa chaiko.Kuchena kwakagadzikana kunogona kusvika 93%, uye kuchena kwehupfumi ndeye 80% ~ 90%;nguva yekugadzirwa kweokisijeni inokurumidza, uye kuchena kunogona kusvika 80% kana kupfuura mukati memaminitsi makumi matatu;unit Simba rekushandisa rinongori 0.32kWh/Nm3～0.37kWh/Nm3.Chechina, kuenzanisa kwekumanikidza swing adsorption kugadzirwa kweokisijeni uye kugadzirwa kweokisijeni ye cryogenic ine maitiro anotevera: kudyara kwakaderera, nzira iri nyore, basa renyika shoma, midziyo mishoma, uye zvikamu zvishoma zvinofamba;dhigirii repamusoro re automation, manejimendi asina kurongwa anogona kuitika;inogona kusangana nezvinodiwa zvekuputika kwevira rakapfuma Oxygen blast process zvinodiwa.
