HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Kulekanitsa mpweya wozizira (kulekanitsa mpweya wotentha pang'ono) ndi zida zodziwika bwino zopangira nayitrogeni (monga kulekanitsa nembanemba ndi makina opangira nayitrogeni othamanga) ndi njira zazikulu zopangira nayitrogeni m'mafakitale. Ukadaulo wolekanitsa mpweya wozizira umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kuthekera kwake kopanga nayitrogeni bwino komanso kuyera bwino. Nkhaniyi ifufuza bwino ubwino ndi kusiyana pakati pa kulekanitsa mpweya wozizira ndi zida zopangira nayitrogeni, kuchita kusanthula koyerekeza pankhani ya kuyera kwa nayitrogeni, kugwiritsa ntchito zida, ndi ndalama zogwirira ntchito, kuti tipereke chitsogozo chosankha ukadaulo woyenera wopanga nayitrogeni. Kuyera kwa nayitrogeni

Ubwino umodzi waukulu wa kulekanitsa mpweya wozama wa cryogenic popanga nayitrogeni ndikuti ukhoza kukhala ndi chiyero chapamwamba kwambiri cha nayitrogeni. Kulekanitsa mpweya wozama wa cryogenic nthawi zambiri kumatha kupanga nayitrogeni yokhala ndi chiyero choposa 99.999%, chomwe ndi chofunikira kwambiri pa ntchito zomwe zimafuna nayitrogeni yoyera kwambiri, monga kupanga zamagetsi, kupanga mankhwala, ndi mafakitale amlengalenga. Mosiyana ndi zimenezi, zida zopangira nayitrogeni yolekanitsa ndi membrane zimatha kungopereka nayitrogeni ndi chiyero cha 90% mpaka 99.5%, pomwe zida zopangira nayitrogeni zokakamiza kugwedezeka (PSA) zimatha kupereka nayitrogeni ndi chiyero chofika 99.9%, koma sizingafanane ndi magwiridwe antchito a kulekanitsa mpweya wozama wa cryogenic. Chifukwa chake, kulekanitsa mpweya wozama wa cryogenic kumakhala kopikisana kwambiri m'mafakitale omwe amafunikira mpweya woyera kwambiri.

Kuchuluka kwa kupanga nayitrogeni

Magawo olekanitsa mpweya wa deep cryogenic ali ndi mphamvu yopangira nayitrogeni wambiri, zomwe zimapangitsa kuti akhale oyenera kwambiri pazochitika zomwe zimafuna nayitrogeni wambiri, monga mphero zachitsulo ndi zomera zamankhwala. Chifukwa chakuti kulekanitsa mpweya wa deep cryogenic kumasungunula mpweya kutentha kochepa kenako kumalekanitsa nayitrogeni ndi mpweya, mphamvu yake yopangira ya unit imodzi imatha kufika mazana kapena zikwi za ma cubic metres pa ola limodzi. Mosiyana ndi zimenezi, zida zopangira nayitrogeni zolekanitsa ndi kukakamiza swing adsorption zili ndi mphamvu zochepa zopangira, zomwe nthawi zambiri zimakhala zoyenera kwa ogwiritsa ntchito mafakitale ang'onoang'ono ndi apakatikati omwe amafunikira nayitrogeni kuyambira makumi mpaka mazana a ma cubic metres pa ola limodzi. Chifukwa chake, pazochitika zomwe zimafuna nayitrogeni wambiri, kulekanitsa mpweya wa deep cryogenic kumatha kukwaniritsa zosowa za mabizinesi.

Ndalama zogwirira ntchito

Poganizira za ndalama zogwirira ntchito, zida zolekanitsira mpweya wa deep cryogenic ndizotsika mtengo kwambiri pakugwira ntchito kwakukulu kosalekeza. Ndalama zoyambira zoyika zida zolekanitsira mpweya wa deep cryogenic ndizokwera, koma panthawi yogwira ntchito kwa nthawi yayitali, mtengo wa gasi udzakhala wotsika. Makamaka m'malo omwe kufunikira kwa nayitrogeni ndi mpweya wambiri nthawi imodzi, kulekanitsa mpweya wa deep cryogenic kumatha kuchepetsa kwambiri mtengo wonse wopanga mpweya kudzera mukupanga pamodzi. M'malo mwake, kupanga nayitrogeni pogwiritsa ntchito mphamvu yothamanga komanso ukadaulo wolekanitsa wa nembanemba umagwiritsa ntchito mphamvu zambiri, makamaka popanga nayitrogeni woyera kwambiri. Ndalama zogwirira ntchito ndizokwera kwambiri, ndipo magwiridwe antchito azachuma sali okwera kwambiri ngati kulekanitsa mpweya wa deep cryogenic pamene kuchuluka kwa nayitrogeni kuli kwakukulu. Zochitika zomwe zingagwiritsidwe ntchito

Chipangizo cholekanitsa mpweya chotchedwa cryogenic air distribution chimagwiritsidwa ntchito kwambiri popanga mafakitale akuluakulu komwe kumafunika nayitrogeni ndi mpweya, monga m'mafakitale achitsulo, mankhwala, ndi petrochemical. Kumbali ina, zida zopangira nayitrogeni zothira mpweya wo ...

Kutha kupanga gasi

Ubwino wina waukulu wa kulekanitsa mpweya wa cryogenic ndi mphamvu yake yopangira mpweya. Kulekanitsa mpweya wa cryogenic sikuti kumangopanga nayitrogeni komanso kungapangitsenso mpweya wina wa mafakitale monga mpweya ndi argon, womwe umagwiritsidwa ntchito kwambiri pakusungunula zitsulo, kupanga mankhwala, ndi madera ena. Chifukwa chake, ukadaulo wolekanitsa mpweya wa cryogenic ndi woyenera mabizinesi omwe ali ndi zosowa zosiyanasiyana za mpweya ndipo ungachepetse kwambiri ndalama zonse zogulira mpweya. Mosiyana ndi zimenezi, zida zothira mpweya wa pressure swing ndi membrane nthawi zambiri zimangopanga nayitrogeni, ndipo kuyera ndi kutulutsa kwa nayitrogeni wopangidwayo kumakhala ndi zoletsa zambiri.

Kuteteza chilengedwe ndi kugwiritsa ntchito bwino mphamvu

Machitidwe olekanitsa mpweya wa cryogenic alinso ndi ubwino wina pankhani yoteteza chilengedwe komanso kugwiritsa ntchito bwino mphamvu. Popeza kulekanitsa mpweya wa cryogenic kumagwiritsa ntchito njira yolekanitsa thupi ndipo sikufunikira mankhwala, sikuyambitsa kuipitsa chilengedwe. Kuphatikiza apo, kudzera mu kapangidwe kabwino ndi ukadaulo wobwezeretsa kutentha, kugwiritsa ntchito bwino mphamvu kwa zida zolekanitsa mpweya wa cryogenic kwakhala bwino kwambiri. Mosiyana ndi zimenezi, zida zopangira nayitrogeni zomwe zimafuna kupopera mphamvu zimafuna njira zopopera madzi pafupipafupi komanso kuchotsa madzi, zomwe zimapangitsa kuti mphamvu zigwiritsidwe ntchito kwambiri. Zipangizo zopangira nayitrogeni zomwe zimalekanitsa nembanemba, ngakhale kuti zimagwiritsidwa ntchito mphamvu zochepa, zili ndi mphamvu zochepa, makamaka ngati zili zoyera kwambiri komanso zimafunikira kuyenda kwakukulu, kugwiritsa ntchito mphamvu zake sikwabwino ngati zida zolekanitsa mpweya wa cryogenic.

Kusamalira ndi kugwiritsa ntchito

Kusamalira makina olekanitsa mpweya wa cryogenic ndi kovuta kwambiri ndipo kumafuna akatswiri odziwa bwino ntchito kuti aziyang'anira ndi kusamalira nthawi zonse. Komabe, chifukwa cha magwiridwe antchito ake okhazikika komanso nthawi yayitali ya zida, mayunitsi olekanitsa mpweya wa cryogenic amatha kugwira ntchito bwino nthawi yayitali. Mosiyana ndi zimenezi, kusamalira makina olekanitsa mpweya wa cryogenic ndi zida zothira mpweya wa pressure swing ndikosavuta, koma zigawo zake zazikulu, monga ma adsorbents ndi zigawo za membrane, zimatha kuipitsidwa kapena kukalamba, zomwe zimapangitsa kuti makinawo azikonzedwa nthawi yochepa komanso azikhala ndi nthawi yayitali yokonza, zomwe zingakhudze chuma komanso kudalirika kwa zipangizozo kwa nthawi yayitali.

Chidule

Pomaliza, ukadaulo wolekanitsa mpweya wozizira kwambiri uli ndi ubwino waukulu kuposa zida zopangira nayitrogeni zomwe zimalowetsedwa ndi kupanikizika kwamphamvu komanso kulekanitsa kwa nembanemba potengera kuyera kwa nayitrogeni, kuchuluka kwa kupanga, ndalama zogwirira ntchito, komanso kupanga mpweya pamodzi. Kulekanitsa mpweya wozizira kwambiri ndikoyenera makamaka kwa mabizinesi akuluakulu, makamaka m'malo omwe pali zofunikira zambiri za kuyera kwa nayitrogeni, kufunikira kwa mpweya, ndi kuchuluka kwa kupanga. Kwa mabizinesi ang'onoang'ono ndi apakatikati kapena omwe ali ndi kufunikira kwa nayitrogeni kosinthasintha komanso kuchuluka kochepa kwa kupanga, zida zopangira nayitrogeni zomwe zimalowetsedwa ndi kukakamizidwa kwa kugwedezeka ndi kusiyana kwa nembanemba ndi njira zabwino kwambiri zachuma. Chifukwa chake, mabizinesi ayenera kupanga zisankho zoyenera kutengera zosowa zawo zenizeni ndikusankha zida zoyenera kwambiri zopangira nayitrogeni.

Ndife opanga ndi kutumiza kunja kwa chipangizo cholekanitsa mpweya. Ngati mukufuna kudziwa zambiri za ife:
