Uyilo kunye nokwakhiwa kwezitofu zehydrogenation
Isishwankathelo:
Isithando somlilo sehydrogenation luhlobo lwesithando somlilo esityhubhu, esicoca kwaye sicoca ioyile eluhlaza ngokususa ukungcola kwayo, okufana nesalfure, ioksijini, kunye nenitrogen, kunye ne-olefin egcwala ngexesha lehydrogenation, ngokusebenzisa ii-cracking kunye ne-isomerization reactions kuxinzelelo oluphezulu (100-150Kg/Cm2) kunye nobushushu (370-430℃). Ngokusekelwe kwiintlobo ezahlukeneyo zeoyile eluhlaza ecociweyo, kukho izithando zedizili zehydrogenation, izithando ze-hydrodesulfurization zeoyile ezisele, izithando ze-hydrogenation zepetroli njalo njalo.
Ulwakhiwo lwesithando somlilo sehydrogenation lufana nolwesithando somlilo esiqhelekileyo esifuthayo, ngokwemilo yesilinda okanye ibhokisi. Isithando somlilo ngasinye senziwe yigumbi lemitha kunye negumbi le-convection. Ubushushu kwigumbi le-radiation budluliselwa ikakhulu yimitha, kwaye ubushushu kwigumbi le-convection budluliselwa ikakhulu yi-convection. Ngokweemeko zokusabela ze-hydrogenation, ukuqhekeka, kunye ne-isomerization, ubushushu besithando somlilo se-hydrogenation bumalunga ne-900°C. Ngenxa yeempawu ezingentla zesithando somlilo se-hydrogenation, i-fiber lining isetyenziswa kuphela kwiindonga kunye nomphezulu wegumbi le-radiant. Igumbi le-convection lidla ngokuphoswa nge-refractory castable.
Ukuchonga izinto zokubopha ilayini:
Xa kujongwaubushushu besithando (buqhele ukuba malunga900℃)kwayeumoya obuthathaka wokunciphisangaphakathiihisithando somoyanjengoiminyaka yethu yamava oyilo nokwakha kunyeinyani yokubainani elikhulu leIzitshisi zihlala zisasazwa kwisithando somlilo phezulu nasezantsi nasemacaleni odonga, izinto zokwambathisaisithando se-hydrogenationKugqitywe ekubeni kuqukwe ulwelo lwezitena ezikhaphukhaphu ze-CCEFIRE oluyi-1.8-2.5m ubude. Iindawo eziseleyo zisebenzisa izinto zefayibha yeseramikhi ye-CCEWOOL ephezulu njengezinto ezishushu kumphezulu welwelo, kwaye izinto zelwelo olungasemva lwezinto zefayibha yeseramikhi kunye nezitena ezikhaphukhaphu zisebenzisa iingubo zefayibha ezisemgangathweni ze-CCEWOOL.
Ulwakhiwo lwelayini:
Ngokwendlela ezisasazwa ngayo ii-nozzles ze-burner kwi-hydrogenation oven, kukho iintlobo ezimbini zezakhiwo ze-oven: i-oven ye-cylindrical kunye ne-oven yebhokisi, ngoko ke kukho iintlobo ezimbini zezakhiwo.
Isithando somlilo esisilinda:
Ngokusekelwe kwiimpawu zesakhiwo sesithando somlilo esisilinda, inxalenye yesitena esikhanyayo ezantsi kweendonga zesithando segumbi elikhazimlayo kufuneka ifakwe iithayile ngeengubo zefayibha ze-ceramic ze-CCEWOOL, emva koko ifakwe izitena ze-CCEFIRE ezikhanyayo; iindawo eziseleyo zinokufakwa iithayile ngeeleya ezimbini zeengubo zefayibha ze-ceramic eziqhelekileyo ze-CCEWOOL, emva koko ifakwe iinxalenye zefayibha ze-ceramic ze-aluminium ephezulu kwisakhiwo se-herringbone anchoring.
Umphezulu wesithando somlilo usebenzisa iileya ezimbini zeengubo zefayibha ze-ceramic eziqhelekileyo ze-CCEWOOL, uze emva koko upakishwe ngeemodyuli ze-aluminium ephezulu kwisakhiwo se-ankile esixhonywe ngomngxuma omnye kunye neemodyuli ezisongwayo ezidityaniswe eludongeni lwesithando somlilo kwaye ziqiniswe ngezikrufu.
Isithando somlilo sebhokisi:
Ngokusekelwe kwiimpawu zesakhiwo sesithando sebhokisi, inxalenye yesitena esikhanyayo ezantsi kweendonga zesithando segumbi elikhazimlayo kufuneka ifakwe iithayile ngeengubo zefayibha ze-ceramic ze-CCEWOOL, emva koko ifakwe izitena ezikhazimlayo ze-CCEFIRE; ezinye zingafakwa iithayile ngeeleya ezimbini zeengubo zefayibha ze-ceramic eziqhelekileyo ze-CCEWOOL, emva koko ifakwe iinxalenye zefayibha ze-aluminium eziphezulu kwisakhiwo se-anchor yesinyithi se-angle.
Umphezulu wesithando somlilo usebenzisa iileya ezimbini ezineethayile zeengubo zefayibha zeseramikhi eziqhelekileyo ze-CCEWOOL ezifakwe iimodyuli zefayibha zeseramikhi eziphezulu kwisakhiwo seankile esixhonywe ngomngxuma omnye.
Ezi ntlobo zimbini zesakhiwo seenxalenye zefayibha ziqinile xa zifakelwa kwaye zilungiswa, kwaye ulwakhiwo lukhawuleza kwaye lulula ngakumbi. Ngaphezu koko, kulula ukuziqhekeza nokuzihlanganisa ngexesha lokugcinwa kwazo. I-lining yefayibha icocekile kakuhle, kwaye ukusebenza kwe-insulation yobushushu kuyamangalisa.
Uhlobo lolungiselelo lokufakelwa kwe-fiber lining:
Ngokweempawu zesakhiwo sokubambelela seenxalenye zefayibha, iindonga zesithando somlilo zisebenzisa iinxalenye zefayibha "herringbone" okanye "angle iron", ezicwangciswe kwicala elinye kwicala lokusonga. Iingubo zefayibha zezinto ezifanayo phakathi kwemigca eyahlukeneyo zisongwa zibe yi-U ukuze zibuyisele ukuncitshiswa kwefayibha.
Kwizinto zefayibha zokuhombisa umngxuma ophakathi ezifakwe kumgca ophakathi ukuya kumphetho wesithando somlilo esisilinda phezulu kwesithando somlilo, kusetyenziswa ulungiselelo "lomgangatho weparquet"; iibhloko zokugoba ezisemaphethelweni ziqiniswe ngezikrufu ezidityanisiweyo kwiindonga zesithando somlilo. Iimodyuli zokugoba ziyanda kwicala eliya eludongeni lwesithando somlilo.
Izixhobo zefayibha zokunyusela umngxuma ophakathi phezulu kwesithando sebhokisi zithatha ilungiselelo "lomgangatho weparquet".
