I-nitrogen isetshenziswa kabanzi njengegesi yokuvikela engasebenzi kahle ezinqubweni eziningi zezimboni—kusukela ekugqokeni ngamakhemikhali nasekupakisheni ukudla kuya ekukhiqizeni izinto zikagesi kanye nokwelashwa kokushisa kwensimbi. Ngenxa yokuthi i-nitrogen ayishisi futhi ayisebenzi ezintweni eziningi, ivame ukubhekwa njengegesi “elula” ukuyicindezela. Kodwa-ke, onjiniyela kanye nabasebenzi bezitshalo ngezinye izikhathi babuza umbuzo obalulekile: Ingabe i-nitrogen ingancibilika ngempela ngaphakathi kwe-compressor ngesikhathi sokusebenza okuvamile? Futhi uma kunjalo, yiziphi izingozi lokho okuzilethayo, futhi ukuklama nokulawula i-compressor efanele kungayivimbela kanjani?
Lesi sihloko sichaza izimo zomzimba lapho i-nitrogen ingancibilika khona, ukuthi kungani lokho kuyingozi kumuntui-nitrogen compressor, nokuthi yiziphi izindlela zokuklama nezokusebenza ezigcina inqubo yokucindezela iphephile esigabeni segesi.
I-nitrogen incibilika ngaphansi kwengcindezi kanye nokushisa okungakanani?
I-nitrogen akuyona igesi "ehlala njalo" ngomqondo oqinile—ingancibilikiswa uma ipholiswa ngaphansi kwezinga lokushisa layo elibucayi futhi icindezelwe ngokwanele. Izinga lokushisa elibucayi le-nitrogen licishe libe yi--147 °C (-233 °F). Ngaphezu kwaleli zinga lokushisa, akukho ngcindezi engancibilikisa i-nitrogen; izohlala inguketshezi noma igesi elibucayi kakhulu. Ngaphansi kwe--147 °C, i-nitrogen ingancibilika ibe uketshezi lapho ingcindezi idlula ingcindezi yayo yomhwamuko.
Ekucindezelweni okuvamile kwezimboni, i-nitrogen ingena kwi-compressor ekushiseni okujwayelekile (ngokuvamile okungu-20–40°C) bese ikhishwa ekushiseni okuphezulu (ngokuvamile okungu-100–150°C). Kuyo yonke le nqubo, izinga lokushisa legesi lihlala lingaphezulu kakhulu kuka-147°C. Ngakho-ke, ngaphansi kwezimo zokusebenza ezijwayelekile, akukho nhlobo ingozi yokuthi i-nitrogen incibilike ngaphakathi kwe-compressor, kungakhathaliseki ukuthi ingcindezi ikhuphuka kangakanani.
Pho kungani ubuza lo mbuzo?
Ukukhathazeka kuvame ukuvela ezimweni ezimbili:
- Ukuqala kokubanda noma amazinga okushisa aphansi kakhulu: Uma i-compressor itholakala esimweni sezulu esibandayo kakhulu (isb., izimo zase-Arctic) futhi umthombo we-nitrogen nawo ubanda kakhulu, igesi ingase ingene kwi-compressor emazingeni okushisa asondela ku--50 °C noma ngaphansi. Nakuba isengaphezu kuka--147 °C, abanye onjiniyela bakhathazeka ngemiphumela yokupholisa yendawo.
- Ukupholisa Kokwanda: Lapho igesi ecindezelwe inwebeka nge-valve noma i-orifice (isb., ngesikhathi sokwehlisa ingcindezi), izinga lokushisa layo lehla kakhulu (umphumela we-Joule-Thomson). Uma i-nitrogen ecindezelwe kakhulu inwebeka ngokuzumayo ibe yingcindezi ephansi, izinga lokushisa lingawa ngaphansi kuka--147 °C, okubangela uketshezi. Lokhu akwenzekingaphakathiigumbi lokucindezela le-compressor kodwa lingenzeka ngezansi komfula, isibonelo, esiteshini sokunciphisa ingcindezi noma inqubo ye-cryogenic.
Ngaphakathi kwe-nitrogen compressor eklanywe kahle—akukho bungozi
Kwi-compressor ye-nitrogen esebenza ngaphakathi kwemingcele yayo yokuklama, izinga lokushisa legesi alikaze lifike eqophelweni elibalulekile. Amazinga okushisa okukhipha ngokuvamile agcinwa phakathi kuka-120 °C no-150 °C ukuze kuphephe futhi kuphile impilo yokugcoba (kumamodeli agcotshwe). Ngisho noma kunengcindezi efinyelela ku-350 bar noma ngaphezulu, i-nitrogen ihlala inguketshezi olubucayi kakhulu noma igesi, hhayi uketshezi. Ngakho-ke, umonakalo womshini ovela ekushayweni koketshezi (ukukhiya kwe-hydraulic) noma ukuminyana kwangaphakathi akuyona inkinga enkonzweni evamile yokucindezela i-nitrogen.
Kunini lapho ukudakwa kungaba yinkinga khona? Futhi ungakugwema kanjani?
Nakuba ukuncibilika ngaphakathi kwe-compressor kungeyona ingozi engokoqobo, kunezimo ezimbili zenqubo lapho i-nitrogen ewuketshezi ingase yakheke khona ohlelweni lwe-compressor, futhi lezi zidinga ukwakheka okucophelelayo:
1. Ukupholisa phakathi kwesiteji okunezinga lokushisa eliphansi kakhulu le-coolant
Uma i-compressor inama-intercooler asebenzisa isiqandisi noma amanzi abandayo ukupholisa igesi phakathi kwezigaba, kungenzeka ukuthi ipholise i-nitrogen ngokweqile. Uma izinga lokushisa legesi ngemva kwe-intercooler lehla ngaphansi kwephuzu lamazolo lanoma yimuphi umswakama (uma ukhona), ukuminyana kwamanzi kuyingozi. Kodwa nge-nitrogen emsulwa, eyomile, i-intercooler kuzodingeka ipholise igesi ngaphansi kuka--147°C ukuze ibangele uketshezi—okuyinto engakaze yenzeke emisebenzini yezimboni.
- Ukugwema: Sebenzisa umoya ozungezile noma amanzi okupholisa avamile (hhayi uketshezi oluyi-cryogenic) ukuze upholise. Setha amazinga okugeleza kwe-coolant ukuze ugcine amazinga okushisa egesi ephumayo engaphezu kuka-0 °C (noma ngaphezulu kuka--147 °C, okuyiqiniso ngokuzenzakalelayo).
2. Ukwanda kokucindezela okuphezulu phansi komfula
Uma i-nitrogen ecindezelwe igcinwa ngomfutho ophezulu bese inwetshwa ibe yingcindezi ephansi kakhulu nge-valve (isibonelo, esiteshini sokugcwalisa isilinda segesi noma i-skid yokwehlisa ingcindezi), ukwehla kwezinga lokushisa kungabangela ukubanda komswakama noma ngisho nokuncibilika kwe-nitrogen uma ukwehla kwengcindezi kukhulu kakhulu futhi izinga lokushisa lokuqala liphansi kakhulu.
- Ukugwema: Shisisa i-nitrogen ngaphambi kokunwetshwa noma sebenzisa izigaba eziningi zokunwetshwa ngokuphinda ufudumale. Faka isihlukanisi somswakama noketshezi ngezansi komfula uma kukhona ingozi yokuthi uketshezi ludlulele.
Kungani ukukhetha i-compressor efanele kanye nomklamo wenqubo kubalulekile
Uhlelo lwe-nitrogen compressor oluklanywe kahle kufanele:
- Gcina amazinga okushisa egesi ephephile ngaphezu kwephuzu elibalulekile (okuyinto ezenzakalelayo ezimweni ezizungezile).
- Sebenzisa ukupholisa okungapholisi igesi ngokweqile (isib., ama-intercooler asayizi ofanele anokulawula izinga lokushisa).
- Faka izingidi zokuphepha ezivala i-compressor uma amazinga okushisa okukhipha ephansi kakhulu (kungenakwenzeka) noma ephezulu kakhulu.
- Uma ufaka indawo ebanda kakhulu, cabanga ngokushisa kwangaphambili kwegesi yokungena noma amakamelo okucindezela afudumele ukuze ugcine amazinga okushisa okungenisa angaphezu kuka-20°C.
Inzuzo ye-Xuzhou Huayan: Ama-compressor e-nitrogen enziwe ngokwezifiso ukuze asebenze ngendlela ethembekile, engenamanzi
Kwa-Xuzhou Huayan Gas Equipment Co., Ltd., besilokhu siklama futhi sikhiqiza ama-compressor e-nitrogen iminyaka engaphezu kwengu-40. Onjiniyela bethu bayaqonda ukuthi igesi "elula" efana ne-nitrogen isadinga ubunjiniyela obucatshangelwe kahle ukuze kugwenywe izinkinga ezingavamile kodwa ezingaba khona njengokupholisa ngokweqile, ukuminyana komswakama, noma ukunciphisa ingcindezi okungafanele.
- Ukuklama nokukhiqiza ngaphakathi endlini - Silawula yonke imininingwane: ukucushwa kwesiteji, usayizi we-intercooler, ukukhethwa kwezinto, kanye nezinsimbi zokuphepha. Lokhu kuqinisekisa ukuthi i-nitrogen compressor yakho isebenza ngokuphephile ngaphansi kwezimo zakho ezithile ze-ambient kanye nezinqubo.
- Kwenzelwe wena uhlelo lwakho lokusebenza – Kungakhathaliseki ukuthi udinga iyunithi yesigaba esisodwa yokumboza ngengcindezi ephansi noma i-compressor yesigaba esine yokugcwalisa isilinda enengcindezi ephezulu, silungisa umklamo ukuze sigweme noma iyiphi ingozi yokuncibilika kwegesi noma ukujiya.
- Okuhlangenwe nakho okuqinisekisiwe—Ama-compressor ethu e-nitrogen asetshenziswa ezindaweni zokucwenga, ezitshalweni zamakhemikhali, ezindwangu ze-elekthronikhi, kanye nasezindaweni zokupakisha ukudla emhlabeni wonke—ezimweni zezulu kusukela ekubandeni kwe-Arctic kuya ekushiseni kwasehlane.
- Ukusekelwa okugcwele - Sinikeza iziqondiso ezicacile mayelana nokulawulwa kwamanzi okupholisa, izindawo zokushisa eziphakathi kwezigaba, kanye nemikhuba yokukhulisa ephephile ngezansi komfula.
Isiphetho
Kuzo zonke izinjongo zezimboni ezisebenzayo, i-nitrogen ayincibiliki ngaphakathi kwe-compressor ye-nitrogen eklanywe kahle ngoba izinga lokushisa legesi lihlala liphezulu kakhulu kunezinga lokushisa elibalulekile elingu--147 °C. Izingozi zangempela zisekukhuleni noma ekusetshenzisweni kabi kwama-coolant e-cryogenic—izingozi ezingasuswa ngokuklama inqubo ezwakalayo. Ngokukhetha i-compressor ye-nitrogen eklanywe kahle evela kumkhiqizi onolwazi futhi ulandele imikhuba efanele yokusebenza, ungajabulela ukucindezelwa kwe-nitrogen okuphephile, okuthembekile, nokungancibiliki amashumi eminyaka.
Uma uhlela uhlelo olusha lokucindezela i-nitrogen noma ukhathazekile ngezingozi zokuncibilika koketshezi ekusethweni kwakho kwamanje, khuluma nonjiniyela asebexazulule lezi zinselele iminyaka engaphezu kwengu-40.
