Qokelela ngoku!Iingxaki eziqhelekileyo kunye nokunyangwa kweejenereyitha ze-nitrogen ezinobunyulu obungekho kumgangatho (Icandelo 2)
Njengoko sonke sisazi, ukucoceka kwejenereyitha yenitrogen ibalulekile kwimveliso.Ukungcola kwe-nitrogen akuchaphazeli nje ukubonakala kwe-welding, kodwa kukhokelela kwi-oxidation yemveliso kunye neziphene zenkqubo, kwaye zibangele iingozi ezinkulu zokhuseleko kwimichiza kunye nokucima umlilo kumashishini.
Inqaku langaphambili elithi "Iingxaki eziqhelekileyo kunye noNyango lwe-Non-standard Purity of Nitrogen Generators" wabelane ngobudlelwane phakathi kokungcola kwe-nitrogen kwi-nitrogen generator kunye nokungaphumeleli komatshini kwezixhobo ngokwazo kunye neenkqubo ezixhasayo, kunye neempembelelo ezibangelwayo kunye nezisombululo.Kweli nqaku, siza kwabelana ngakumbi ngempahla eyomileyo evela kwizinto zangaphandle: impembelelo yezixhobo zokusebenza ubushushu bume, iqondo lomoya ocinezelweyo (ubumanzi), kunye neoli eshiyekileyo yomoya ekucocekeni kwejenereyitha yenitrogen kunye nokusebenza kwezixhobo.
1.
Izixhobo zokuvelisa i-nitrojeni zenzelwe indawo yokusebenza ezinzileyo yesixhobo engqondweni, ngokuqhelekileyo kuluhlu lwe-0-45 ° C, oku kuthetha ukuba isixhobo sinokwenza ngokuqhelekileyo ngaphakathi kolu luhlu lobushushu.Ngokuchasene noko, ukuba iqhutywa ngaphandle kobushushu obuyiliweyo be-ambient, iya kuzisa iingxaki ezinjengokuthotywa kokusebenza kunye nezinga eliphezulu lokungaphumeleli.
Xa ubushushu be-ambient budlula i-45 ° C, ukushisa kwe-compressor yomoya kuya kuba phezulu kakhulu, okuya kwandisa umthwalo kwi-dryer dryer.Kwangaxeshanye, kunokubangela ukuba isixhobo sokomisa umkhenkce sihambe kumaqondo obushushu aphezulu.Indawo yombethe womoya ocinezelweyo ayinakuqinisekiswa, nto leyo eya kuchaphazela kakhulu ijenereyitha yenitrogen.isiphumo.Ngaphantsi kwesiseko sokucoceka okufanayo, izinga lokuhamba kwemveliso ye-nitrogen iya kuhla ngaphezu kwe-20%;ukuba izinga lokuhamba kokuveliswa kwe-nitrogen lihlala lingatshintshi, ukucoceka kwegesi ye-nitrogen akuyi kuhlangabezana neemfuno zoyilo.Ngovavanyo lwelabhoratri oluphezulu noluphantsi lobushushu, sifumanise ukuba xa iqondo lobushushu elisezantsi lingaphantsi kwe-20°C, ezinye izincedisi zombane azikwazi ukuqaliswa, okanye isenzo asiqhelekanga, nto leyo eya kubangela ngokuthe ngqo ukuba ijenereyitha yenitrogen ingaphumeleli ukuqalisa nokusebenza.
isisombululo
Ukuphucula imeko-bume yegumbi lekhompyutha, inkqubo yokungenisa umoya kufuneka iphuculwe ehlotyeni, kwaye iimeko zokufudumeza kufuneka zandiswe ebusika ukuze kuqinisekiswe ukuba ubushushu begumbi lekhompyutha buphakathi koluhlu olufanelekileyo.

Isiqulatho sokufuma (indawo yoxinzelelo lombethe) emoyeni ocinezelweyo sinempembelelo ethe ngqo kwijenereyitha yenitrogen/ikhabhoni yesihluzo semolekyuli, ngoko ke ijenereyitha yenitrogen ineemfuno ezingqongqo kumgangatho womoya ocinezelweyo ngaphambili.
Imeko yokwenyani yempembelelo yokususwa kwamanzi kunye nesiphumo sokwahlulwa kwamanzi kwesomisi esibandayo kwijenereyitha yenitrogen:
Imeko 1: Umsebenzisi akazange afake i-drainer ngokuzenzekelayo kwitanki yokugcina umoya ye-compressor yomoya, kwaye akazange akhuphe amanzi rhoqo, okubangele umxholo omkhulu wokufuma kwi-air intake ye-dryer ebandayo, kunye nenqanaba lesithathu lokucoca amanzi. i-air inlet kunye ne-outlet yesomisi esibandayo ayizange ifake i-drainer Kwaye i-drainage ye-drainage eqhelekileyo, ekhokelela kumxholo wamanzi aphezulu kakhulu kwinkqubo, ebangela ukuba i-carbon filter isebenze efakwe ekupheleni ngasemva ukufunxa amanzi kunye nokwenza iibhloko ukuvala umoya ocinezelweyo. umbhobho, kwaye uxinzelelo lokungenisa luyancitshiswa (ukungena ngokwaneleyo), okubangela ukucoceka kwejenereyitha ye-nitrogen engahambelani nomgangatho.Ingxaki yasonjululwa ngokongeza inkqubo yokuhambisa amanzi emva kokuguqulwa.
Ityala lesi-2: Isahluli samanzi sesomisi esibandayo somsebenzisi asilungile, nto leyo ekhokelela ekubeni amanzi okupholisa angohlulwa kwangexesha.Emva kokuba isixa esikhulu samanzi angamalwelo singena kwijenereyitha yenitrogen, iivalvu ezi-2 zesolenoid zaphuka kwisithuba seveki, kwaye ingaphakathi lepiston yesitulo sevalve ye-angle yonakaliswe ngokupheleleyo.Ngamanzi angamanzi, abangela ukuba i-piston seal idle, ibangele ukuba ivalve isebenze ngokungaqhelekanga, kwaye ijenereyitha ye-nitrogen ayikwazi ukusebenza ngokuqhelekileyo.Emva kokutshintsha indawo yokomisa umkhenkce, ingxaki yasonjululwa.
I-1) Kukho ii-micropores kumphezulu we-carbon molecular sieve, ezisetyenziselwa ukubhengeza iimolekyuli ze-oksijini (njengoko kuboniswe kumfanekiso).Xa umxholo wamanzi emoyeni ocinezelweyo unzima kakhulu, i-micropores ye-molecular sieve iya kuncipha kwaye uthuli oluphezu kwe-molecular sieve luya kuwa, oluya kuthintela i-micropores ye-sieve kwaye ibangele ubunzima beyunithi ye-Carbon molecular sieves. ayinakuvelisa ukuhamba kwenitrogen kunye nococeko lwenitrogen olufunwa ngumlinganiselo.
Kunconywa ukuba abasebenzisi bafake i-adsorption dryer kwi-inlet ye-nitrogen generator ukunciphisa umthamo wamanzi womoya ocinezelweyo kwaye uqinisekise ukuba i-carbon molecular sieve ayingcoliswa yioli eninzi kunye namanzi anzima.Ngokuqhelekileyo, ubomi benkonzo ye-molecular sieve inokwandiswa ngeminyaka emi-3-5 (ngokwezinga lokucoceka).

Impembelelo yesiqulatho seoli kumoya oxinanisiweyo kwijenereyitha yenitrogen/isihluzo semolekyuli:
I-1) Naluphi na uhlobo / uhlobo lwe-molecular sieve, amacandelo angadingekile ahlolwe ngaphandle kwe-micropores ebusweni be-molecular sieve ukufumana izinto esizifunayo.Kodwa zonke iisefu zemolekyuli ziyoyika ukungcoliseka kweoyile, kwaye ungcoliseko lweoyile olushiyekileyo lungcoliseko olungenakuguqulwa ngokupheleleyo kwiisefu zemolekyuli, ngoko ke i-inlet yejenereyitha yenitrogen ineemfuno ezingqongqo zeoyile.
2) Njengoko kubonisiwe kulo mfanekiso ungentla, amabala e-oyile aya kugubungela i-micropores kumphezulu we-molecular sieve, ebangela ukuba iimolekyuli zeoksijini zingakwazi ukungena kwi-micropores kwaye zibhengezwe, okukhokelela ekunciphiseni kwemveliso ye-nitrogen, okanye phantsi kwesiseko se-nitrogen. ukuqinisekisa ubungakanani bomqukuqelo wokuqala, ukucoceka kwenitrogen kuya kuba kungafanelekanga kwiminyaka emi-5.
Iindlela zokuphucula ezi ngxaki zingentla: Nika ingqalelo kwi-ventilation yegumbi lomatshini, ukunciphisa ubushushu be-ambient, kunye nokunciphisa inani le-oyile eseleyo emoyeni ocinezelweyo;ukomeleza ukhuseleko ngokusebenzisa izomisi ezibandayo, izomisi ezifunxayo, izihluzi, kunye nekharbhon degreaser esebenzayo;rhoqo ukubuyisela / ukugcina izixhobo zangaphambili zejenereyitha ye-nitrogen, Ukuqinisekisa umgangatho womoya ocinezelweyo unokukhusela kakhulu kwaye andise ubomi benkonzo yejenereyitha ye-nitrogen kunye nokusebenza kweesefu ze-carbon molecular.

Ukushwankathela: izinto zangaphandle ezifana nobushushu obukhoyo begumbi lomatshini, umthamo wamanzi kunye nomxholo we-oyile womoya ocinezelekileyo uya kuchaphazela ukusebenza kwezixhobo zokwenza initrogen, ngakumbi esomisi esibandayo, isomisi esifunxayo kunye nesihluzi esingaphambili Umatshini wokwenza initrogen uya kuchaphazela ngokuthe ngqo izixhobo zokwenza initrogen.Isiphumo sokusetyenziswa kwejenereyitha ye-nitrogen, ngoko ke ukhetho lwezixhobo zokomisa ezikumgangatho ophezulu kunye nolusebenzayo lubaluleke kakhulu kwijenereyitha yenitrogen.
Abavelisi bejenereyitha abaninzi benitrogen abavelisi izixhobo zokucoca umoya ezicinezelweyo ngaphambili.Xa inkqubo ye-nitrogen generator ingaphumeleli, kulula ukuba abavelisi bejenereyitha ye-nitrogen kunye nabavelisi bezomisi ukuba baphephe omnye komnye kwaye bangathathi uxanduva omnye komnye.
Njengomthengisi ogqwesileyo weemveliso zenkqubo yomoya, i-EPS inekhonkco epheleleyo yemveliso, enokubonelela abathengi ngeseti epheleleyo yezixhobo ezifana nezomisi ezibandayo, ezomisi ezifunxayo, izihluzi, iijenereyitha zenitrogen eziphuhliswe ngokuzimeleyo kwaye zenziwe, ezikumgangatho ophezulu. iimveliso zixhotyiswe ngejenereyitha zenitrogen ezikumgangatho ophezulu, ukuze abathengi bathenge kwaye basebenzise ngokuzithemba!
