Ipayipi legesi libhekisela kupayipi elixhumanisayo phakathi kwesilinda segesi kanye ne-instrument terminal. Ngokuvamile liqukethe i-valve yokulawula ibhokisi elilawula i-device-pressure device-valve-pipeline-filter-alamu-terminal kanye nezinye izingxenye. Amagesi athuthwayo amagesi ezinsimbi zelebhu (i-chromatography, ukumuncwa kwe-athomu, njll.) kanyeamagesi ahlanzekile kakhuluI-Gas Engineering Co., Ltd. ingaqedela amaphrojekthi abalulekile okwakhiwa, ukwakhiwa kabusha, kanye nokwandiswa kwemigqa yegesi yelabhorethri (amapayipi egesi) ezimbonini ezahlukahlukene.
Indlela yokuphakelwa kwegesi isebenzisa ukuphakelwa kwegesi okunomfutho ophakathi kanye nokunciphisa ingcindezi yezigaba ezimbili. Ingcindezi yegesi yesilinda ingu-12.5MPa. Ngemva kokunciphisa ingcindezi yesigaba esisodwa, iba yi-1MPa (ingcindezi yepayipi engu-1MPa). Ithunyelwa endaweni yegesi. Ngemva kokunciphisa ingcindezi yezigaba ezimbili, iba yi-. Ingcindezi yokuphakelwa komoya ingu-0.3 ~ 0.5 MPa (ngokuya ngezidingo zethuluzi) futhi ithunyelwa ethuluzini, futhi ingcindezi yokuphakelwa komoya izinzile. Ayingeni kuwo wonke amagesi, inomphumela omncane wokumuncwa, ayinamakhemikhali kugesi othuthwayo, futhi ingalinganisa ngokushesha igesi ethuthwayo.
Igesi ethwalayo ilethwa ethuluzini ngesilinda kanye nepayipi lokulethwa. Ivalvu enendlela eyodwa ifakwa endaweni yokuphuma kwesilinda ukuze kugwenywe ukuxubana komoya kanye nomswakama lapho kufakwa isilinda esikhundleni saso. Ngaphezu kwalokho, kufakwa ivalvu yebhola yokunciphisa ukucindezeleka komoya ngakolunye uhlangothi ukuze kukhishwe umoya kanye nomswakama owengeziwe. Ngemva kokukhipha, yixhume epayipini lethuluzi ukuqinisekisa ubumsulwa begesi esetshenziswa yithuluzi.
Uhlelo lokuphakelwa kwegesi oluphakathi lusebenzisa ukunciphisa ingcindezi yezigaba ezimbili ukuqinisekisa ukuzinza kwengcindezi. Okokuqala, ngemva kokunciphisa ingcindezi, ingcindezi yomugqa owomile iphansi kakhulu kunengcindezi yesilinda, edlala indima yokuvimba ingcindezi yepayipi futhi ithuthukise ukusebenza kahle kohlelo lokuphakelwa kwegesi. Ukuphepha kokusetshenziswa kwegesi kunciphisa izingozi zokusetshenziswa. Okwesibili, kuqinisekisa ukuzinza kwengcindezi yokungena kwegesi yethuluzi, kunciphisa amaphutha okulinganisa abangelwa ukushintshashintsha kwengcindezi yegesi, futhi kuqinisekisa ukuzinza kwethuluzi.
Njengoba ezinye izinto ezisebhodleleni zidinga ukusebenzisa amagesi avuthayo, njenge-methane, i-acetylene, ne-hydrogen, lapho kwenziwa amapayipi ala magesi avuthayo, kufanele kuqashelwe ukugcina amapayipi amafushane ngangokunokwenzeka ukuze kuncishiswe inani lamalungu aphakathi. Ngesikhathi esifanayo, amasilinda egesi kumele agcwaliswe ngegesi engaqhumi. Ekhabetheni lebhodlela, ukuphela kokuphuma kwebhodlela legesi kuxhunywe kudivayisi ye-flashback, engavimbela ukuqhuma okubangelwa ukubuyela emuva kwelangabi ebhodleleni legesi. Ingxenye ephezulu yekhabetheni lebhodlela legesi elingaqhumi kufanele ibe nendawo yokungenisa umoya exhunywe ngaphandle, futhi kufanele kube nedivayisi ye-alamu yokuvuza. Uma kwenzeka ukuvuza, i-alamu ingabikwa ngesikhathi futhi igesi ikhiphe umoya ngaphandle.
Qaphela: Amapayipi anobubanzi obuyi-1/8 mancane kakhulu futhi athambile kakhulu. Awaqondile ngemva kokufakwa futhi awabukeki kahle. Kunconywa ukuthi wonke amapayipi anobubanzi obuyi-1/8 ashintshwe ngo-1/4, bese ufaka ipayipi ekugcineni kwesinciphisi sesibili sokucindezela. Vele ushintshe ububanzi. Ububanzi besilinganiso sokucindezela sesinciphisi sengcindezi se-nitrogen, i-argon, umoya ocindezelweyo, i-helium, i-methane kanye nomoya-mpilo buyi-0-25Mpa, kanti isinciphisi sesibili sokucindezela siyi-0-1.6 Mpa. Ububanzi bokulinganisa besinciphisi sengcindezi sezinga lokuqala se-acetylene singu-0-4 Mpa, kanti isinciphisi sengcindezi sezinga lesibili singu-0-0.25 Mpa. I-nitrogen, i-argon, umoya ocindezelweyo, i-helium, kanye namalunga esilinda se-oxygen abelana ngamalunga esilinda se-hydrogen. Kunezinhlobo ezimbili zamalunga esilinda se-hydrogen. Elinye liyi-joint yesilinda esijikelezayo sangaphambili, elinye lihlehlisiwe. Amasilinda amakhulu asebenzisa ukujikeleza okuphambene, kanti amasilinda amancane asebenzisa ukujikeleza okuphambili. Amapayipi egesi anikezwa ngengxenye yokulungisa amapayipi njalo nge-1.5m. Izingcezu zokulungisa kufanele zifakwe emagobeni nasemaphethelweni womabili evalvu. Amapayipi egesi kufanele afakwe odongeni ukuze kube lula ukufakwa nokugcinwa kwawo.
