Parizvino, maindasitiri eChina ari kukurudzira zvizere kuchengetedza simba uye kushandura kabhoni. Kugadzirwa kweokisijeni panzvimbo yekutsiva okisijeni mumabhodhoro neokisijeni yemvura kwave chinhu chakakosha pakuderedza mitengo mumafekitori makuru, uye huwandu hwekuisa michina yekugadzira okisijeni panzvimbo yekuisirwa hwave huchiwedzera gore negore. Zvisinei, pane dambudziko guru riripo muindasitiri iyi: makambani mazhinji anotsvaga okisijeni yakachena zvakanyanya, zvichiwedzera mari yekudyara mumidziyo uye magetsi; uye mune mamwe mamiriro ekushanda, kuchena kweokisijeni hakusviki pazvinodiwa, zvichikonzera kudzikira kwekushanda zvakanaka kwekugadzira uye kuwedzera kwehuwandu hwezvikanganiso zvechigadzirwa.
Kuchena kweokisijeni kwakanyanya hakusi nani nguva dzose. Maitiro akasiyana ekugadzira uye maindasitiri ari pasi ane mwero wakasimba wekufananidza kuchena. Tichibatanidza standard yenyika yazvino GB/T 3863-2025 Industrial Oxygen Specification uye ma parameter ehunyanzvi emidziyo mikuru yekugadzira okisijeni, chinyorwa chino chinogadzirisa zvizere mazinga mashanu ekuchena kweokisijeni yeindasitiri, michina inoenderana yekugadzira okisijeni, uye mamiriro ezvinhu anoshanda kumaindasitiri ese. Chinobvisawo mafungiro asina kunaka ekusarudza kubatsira mabhizinesi emaindasitiri nevemigodhi kusarudza michina nemazvo uye kudzora mitengo yegesi zvakanyanya.
1. Kuchena kwakaderera (90% ~ 93%):Yakakodzera mamiriro ekutsva ane okisijeni yakawanda uko kudiwa kweokisijeni kwakaderera. 1. Okisijeni yekuwedzera kupisa mumaokisi egirazi, maokisi anotenderera esimende, uye maincinerator emarara:** Izvi zvine chinangwa chekuwedzera kupisa kwemurazvo uye kuderedza kushandiswa kwesimba, pasina kushandisa okisijeni yakachena kwazvo.
2. Kuchena kuri pakati nepakati (93% ~ 95%):Inowanzoshandiswa mukurima gungwa, kuchenesa mvura yakasviba, uye mamwe maitiro madiki ekuoxidation emakemikari. Kuchena uku kwakakwana kune maitiro e aerobic kana maitiro eoxidation akajairika, zvichipa mutengo wakanyanya kushanda.
3. Kuchena kwakanyanya (≥99.2% - 99.6%):Standard yegiredhi rekutanga reindasitiri, yakakodzera kusanganisa nekucheka simbi, kugadzira simbi nesimbi (senge kuburitsa oxygen), kugadzira makemikari (senge ethylene oxidation), uye mamwe maitiro anoda kushanda nesimba kana kudzivirira tsvina.
4. Kuchena kwakanyanya (≥99.9%):Inoshandiswa mukugadzira zvinhu zvakaita semiconductor, kugadzira optical fiber preform, kugadzira aerospace propellants, uye makemikari akakosha. Izvi zvinonyanya kukanganiswa netsvina yakaita sehunyoro nemahydrocarbon, zvichida kucheneswa zvakadzama.
Zvinokosha Zvekudzivirira:
1. Rambai kusanganisa: Okisijeni yemumaindasitiri inogona kunge iine huwandu hushoma hwecarbon monoxide, carbon dioxide, acetylene, nemafuta, asi haifanirwe kushandiswa pakufema kwechiremba, zvikasadaro inokonzera kutsamwa kwemapapu, chepfu, kana kutozvimba kwemapapu.
2. Maitiro anoona kuchena: Kupatsanurwa kwemhepo inopenya kunoita kuti pave nekuchena kwakanyanya (≥99.5%), kudzvanywa kwemhepo inotsvedza (PSA) kunowanzo buritsa kuchena kwe90%-95%, uye kupatsanurwa kwemembrane kunenge kwakaderera (30%-50%). Sarudzo yacho inofanira kuenderana nezvinodiwa zviviri zvekuchena uye huwandu hwegasi zvinoenderana nemamiriro ezvinhu chaiwo.
3. Misiyano Yakajairika: Muyero wenyika weGB/T 3863 unoti giredhi rekutanga reokisijeni muindasitiri rinofanira kuva ≥99.5%, uye giredhi rechipiri ≥99.2%. Mukushandiswa kwaro, kana maitiro acho asina zvirambidzo zvakakosha pakusvibiswa, anenge 93% akakwana kune zvakawanda zvinodiwa pakupisa uye kurima gungwa. Hapana chikonzero chekutsvaga kuchena kwakanyanya kuti uchengetedze mari.
Pfungwa Dzitatu Dzisiri Dzechokwadi Dzinoshandiswa Pakusarudza Maindasitiri:
Pfungwa Isina Kujeka 1: Kuchena kweokisijeni kwakanyanya kunoreva mhedzisiro iri nani yekugadzira. Chokwadi: Kuwedzera kwe1% kwehutsanana kunowedzera zvakanyanya kushandiswa kwesimba remuchina weokisijeni. 93% okisijeni yakakwana pakuita zvinhu zvekuvaka, kurapwa kwemvura yakasviba, uye mabhatiri e lithiamu. Kusarudza 99.5% okisijeni yakakwira kunowedzera zvakananga mitengo yemagetsi neinopfuura 30%.
Pfungwa nhema 2: Magadzirirwo eokisijeni emaindasitiri anogona kutsiva okisijeni yekurapa. Chokwadi: Kunyangwe paine kuchena kwe93%, magadzirirwo eokisijeni emaindasitiri haana michina yekuchenesa gasi rekurapa uye yekusefa uye ane tsvina yakaita sehunyoro neguruva. Haabvumidzwe kushandiswa pakufema kwevanhu. Izvi zviviri zvinotevedzera mitemo yekuchengetedza yakasiyana zvachose.
Ngano 3: Mamiriro ese anotsigira kupisa anoda okisijeni yakachena kwazvo. Chokwadi: Kune maovheni nemabhoyira akajairwa, kuwedzera okisijeni kwe25%-40% kwekupatsanurwa kwemembrane kwakakwana, zvichipa kushanda zvakanaka pamutengo kupfuura majenareta eokisijeni emolecular sieve. Kusarudza modhi yakakodzera zvaunoda ndicho chinhu chikuru pakuderedza mutengo.
Pfupiso:Nheyo huru yekusarudza majenareta eokisijeni emaindasitiri ndeiyi: yakakodzera mamiriro ekushanda, kwete hazvo kuchena kwakanyanya. Kuti pave nerutsigiro rwekutanga rwekupisa, kuwedzera okisijeni pakupatsanurwa kwemembrane kwakakodzera; pakugadzirwa kwemaindasitiri, 93% majenareta eokisijeni ePSA akajairwa anokurudzirwa; maitiro epamusoro-soro chete anoda okisijeni ine kuchena kwakanyanya ye99.5% kana kupfuura. Vasati vatenga majenareta eokisijeni, makambani anofanirwa kutsanangura zvakajeka zvinodiwa zvavo zvekuchena kwegasi uye mwero wekuyerera kuti vawane kugadzirwa kwakachengeteka uye kuchengetedza simba.
