Inkqubo yokudibanisa i-alarm yolwelo kabini kwitanki yokugcina i-cryogenic
Umhla: Dec 14, 2019
Iitanki zokugcina ulwelo lweCryogeniczisetyenziswa kakhulu kwishishini lemichiza. Ngenxa yokuba indawo yokugcina iikhemikhali ezinobungozi, ukwenzela ukuba kuqinisekiswe ukusetyenziswa okukhuselekileyo kweetanki zokugcina ukushisa okuphantsi. Isitywina senitrogen kufuneka sibekwe phakathi kwamaleko angaphakathi nangaphandle etanki yokugcina ubushushu obuphantsi ukuze kugcinwe uxinzelelo olulungileyo lomaleko ophakathi ukuthintela ukungena komoya ofumileyo kwaye kuqinisekiswe ukusebenza kakuhle kokugquma kwe-thermal kwiimveliso zemichiza.
Ukongeza,iitanki zokugcina ubushushu obuphantsikufuneka ixhotyiswe ngamanyathelo okhuseleko ahambelanayo. Itanki yetanki yokugcina i-cryogenic kufuneka ixhotyiswe ngenqanaba le-alarm interlock system. Xa inqanaba lolwelo lwetanki yokugcinwa kweqondo lokushisa eliphantsi liphezulu kunexabiso elimiselweyo, i-alarm yezinga eliphezulu lolwelo ivuliwe, kwaye xa umgangatho ophezulu wolwelo ufikeleleke, inkqubo ye-interlock ivuliwe ukuvala i-valve kumbhobho wokungena kwi-tank yokugcina iqondo lokushisa eliphantsi.
Xa inqanaba le-liquid kwi-tank ye-cryogenic liphantsi kwexabiso elimiselweyo, i-alamu yezinga eliphantsi lolwelo liya kubangelwa. Xa umgangatho ophantsi ufikeleleke, inkqubo ye-interlock ivuliwe, i-valve kumbhobho wokukhupha ulwelo wetanki yokugcina i-cryogenic ivaliwe, kwaye ipompo yokulayisha ivaliwe. Ukongeza, kuya kubakho iiseti ezimbini zokubeka iliso loxinzelelo kunye neenkqubo zokuvala i-alarm. Xa uxinzelelo lwetanki yokugcina ubushushu obuphantsi buphezulu kunexabiso elibekiweyo, i-alam yoxinzelelo oluphezulu iya kuqaliswa, inkqubo yokudibanisa iya kuvulwa, kunye nevalve ezenzekelayo kumbhobho wenkqubo ye-booster iya kuvalwa ukumisa ukuphuculwa. 
Xa i-tank yokushisa ephantsi yokushisa iphantsi kwexabiso elibekiweyo, i-alamu ephantsi yoxinzelelo iya kuqaliswa kwaye i-valve yokulawula i-backflow kwi-outlet ye-BOG compressor iya kuvulwa ukuze kuqinisekiswe ukuba uxinzelelo kwi-tank yokugcina aluyi kwenza uxinzelelo olubi. Xa uxinzelelo oluphantsi lufikelelwe, inkqubo yokudibanisa ivuliwe, ivalve ezenzekelayo kumbhobho we-cryogenic liquid storage tank pressurization system ivuliwe, kunye ne-tank yokugcina i-cryogenic yengxenye yokuphefumula ixinzelelwe kwi-tank yokugcina yangaphakathi.
Akunjalo kuphela, kukho inkqubo epheleleyo yokhuseleko kwi-tank yokugcina imichiza, oko kukuthi, i-valve yokukhusela iqela eliphindwe kabini kunye ne-valve yokuphefumula yeqela eliphindwe kabini, kunye ne-valve yeendlela ezintathu isetyenziselwa ukutshintsha. Xa uxinzelelo lwetanki yangaphakathi ludlula i-25kPa, ivalve yokhuseleko iya kukhulula uxinzelelo; xa i-tank yokugcinwa kwetanki yangaphakathi iphantsi kune -0.5kPa, i-valve yokuphefumula ivula kwaye umoya ungena kwi-tank yokugcina yangaphakathi ukuze ugweme umonakalo wezixhobo.
