Kachipangizo kamene kamagwiritsira ntchito njira zakuthupi kuti alekanitse mpweya wa mpweya m’mlengalenga kuti apeze nayitrojeni amatchedwa jenereta wa nitrogen.Pali mitundu itatu ikuluikulu ya majenereta a nayitrogeni, yomwe ndi cryogenic air separation, molecular sieve air separation (PSA) and the membrane air separation Law.Masiku ano, wopanga majenereta a nayitrogeni-HangZhou Sihope luso co., Ltd.mwachidule kulankhula za mfundo ndi ubwino wa kuthamanga pachimake adsorption mpweya m'badwo.

Kuthamanga kwa adsorption adsorption njira, ndiyo njira ya PSA, ndiyo kutsatsa pamagetsi apamwamba kuti akwaniritse kulekana kwa mpweya, ndi kukwaniritsa kusinthika kwa adsorbent pazitsulo zotsika.Njirayi imachokera ku sieve ya molekyulu yomwe imasankha mayamwidwe a oxygen ndi nayitrogeni mumlengalenga kuti alekanitse mpweya kuti upeze mpweya.Mpweya ukakanikizidwa ndikudutsa munsanja ya adsorption yokhala ndi sieve ya mamolekyulu, ma molekyulu a nayitrogeni amalowetsedwa bwino, ndipo mamolekyu a okosijeni amakhalabe mugawo la mpweya ndikukhala mpweya.Kutsatsa kukafika pamlingo wofanana, mamolekyu a nayitrogeni omwe amalowetsedwa pamwamba pa sieve ya maselo amatulutsidwa ndi kuchepetsa kupanikizika kapena vacuum, ndipo mphamvu yotsatsira ya sieve ya maselo imabwezeretsedwa.Pofuna kupereka okosijeni mosalekeza, chipangizochi nthawi zambiri chimakhala ndi nsanja ziwiri kapena zingapo zotsatsira, nsanja imodzi imatulutsa okosijeni ndipo ina imawononga nsanja, kuti ikwaniritse cholinga chopanga mpweya wopitilira muyeso.

Njira ya PSA imatha kutulutsa mpweya ndi chiyero cha 80% -95%.Kugwiritsa ntchito mphamvu popanga okosijeni nthawi zambiri kumakhala 0.32kWh/Nm3 ~0.37kWh/Nm3, ndipo kuthamanga kwa adsorption kumakhala kopitilira muyeso wa mumlengalenga, nthawi zambiri 30kPa～100kPa.Njirayi ndi yophweka, ikugwira ntchito kutentha, ndi mlingo wa automation High, ukhoza kuzindikira kasamalidwe kopanda anthu, makamaka chitetezo chabwino.Mu njira ya vacuum desorption, kuthamanga kwa chipangizocho kumakhala kochepa, ndipo chidebe sichimayendetsedwa ndi ndondomeko ya chidebe chokakamiza.Malingana ndi chiwerengero cha adsorbers, kuthamanga kwa kuthamanga kwa adsorption kumagawidwa kukhala njira imodzi ya nsanja, ndondomeko ya nsanja ziwiri, ndondomeko ya nsanja zitatu, ndi ndondomeko ya nsanja zisanu.Njira yosanja ya nsanja zisanu ndi imodzi yomwe imagwiritsidwa ntchito kwambiri, yomwe imagwiritsa ntchito mabedi 5 adsorption, 4 blowers ndi 2 vacuum pampu kusunga mabedi 2 mu adsorption ndi vacuum panthawi yonseyi, yomwe imathetsa vuto laukadaulo la oxygen yayikulu. kupanga.

Pressure swing adsorption adsorption oxygenation process ili ndi izi zabwino izi: Choyamba, imagwiritsa ntchito ukadaulo wothamangitsa wodziwikiratu wa kusiyana kwa mpweya wolowera mumlengalenga kuti muchepetse kuchuluka kwa mpweya wa chowuzira, kutalikitsa moyo wautumiki wa zida, ndikuchepetsa mtengo wopanga mpweya.Chachiwiri ndi zida zosavuta, zida zazikulu zowombera Mizu ndi vacuum pump ndizokhazikika komanso zodalirika, ndipo moyo wautumiki wa sieve yama cell ndi zaka zopitilira 10 popanda kukonza.Chachitatu ndi chakuti kuchuluka ndi chiyero cha okosijeni chopangidwa chingasinthidwe molingana ndi ntchito yeniyeni.Chiyero chokhazikika chimatha kufikira 93%, ndipo chiyero chachuma ndi 80% ~ 90%;nthawi yopanga okosijeni ndi yofulumira, ndipo chiyero chimatha kufika 80% kapena kuposa mkati mwa mphindi 30;unit Mphamvu yogwiritsira ntchito ndi 0.32kWh/Nm3 ~ 0.37kWh/Nm3 yokha.Chachinai, kuyerekezera kwa pressure swing adsorption oxygen kupanga ndi cryogenic oxygen kupanga ali ndi makhalidwe awa: ndalama zochepa, njira yosavuta, kuchepa kwa nthaka, zipangizo zochepa, ndi zochepa zosuntha;digiri yapamwamba ya automation, kasamalidwe kopanda munthu kutha kuchitika;imatha kukwaniritsa zofunikira za ng'anjo yophulika yochuluka ya Oxygen kuphulika ndondomeko.
