- I. Ufakelo olungundoqo: Ukulawula iiNkcukacha eziBalulekileyo kwiiSystems
1. Ukufakela uMzimba oPhambili: Qinisekisa ukuzinza kunye nokuLayishwa okufanayo
Umgangatho: Sebenzisa inqanaba lomoya ukujonga isiseko sesithando somlilo ukuqinisekisa ukuba ukuphambuka okuthe nkqo kunye nokuthe tye ≤1‰. Oku kuthintela ukuthambeka okunokubangela umthwalo ongalinganiyo kwiityhubhu zesithando somlilo kunye nokungahambi kakuhle kweoyile yobushushu.
Indlela yokukhusela: Sebenzisa iibholithi ze-ankile (iinkcukacha zebholithi mazihambelane nencwadana yezixhobo). Qinisa ngokulinganayo ukuthintela ukuguqulwa kwesiseko. Kwizixhobo ezinyusiweyo zokutyibiliza, qinisekisa ukuba ukutyibilika kuncanyathiselwe ngokuqinileyo emhlabeni kwaye akukho kushukuma.
Ukuhlolwa kwe-Accessory: Ngaphambi kokufakwa, ukulinganisa i-valve yokukhusela (uxinzelelo olusethiweyo luhlangabezana neemfuno zokuyila, njengamaxesha e-1.05 uxinzelelo lokusebenza) kunye ne-gauge ye-pressure gauge (uluhlu lwe-1.5-3 amaxesha oxinzelelo lokusebenza, ukuchaneka ≥1.6), kwaye ubonise ilebula eqinisekisiweyo. I-thermometers kufuneka ifakwe kwi-oyile ye-oyile kunye nemibhobho yokuphuma ukuze kuqinisekiswe ukubeka iliso ngokuchanekileyo.
2. Ukufakwa kweNkqubo yeMibhobho: Ukuthintela ukuvuza, ukuVinjwa kweGesi, kunye neCoking
Izinto kunye neWelding:Imibhobho yeoli eshushukufuneka yakhiwe ngombhobho wentsimbi ongenamthungo okwaziyo ukumelana nobushushu obuphezulu (njengentsimbi eyi-20# okanye i-12Cr1MoV). Imibhobho ye-galvanized ayivunyelwe (i-zinc layer iphula ngokulula kumaqondo okushisa aphezulu, okukhokelela ekuphekeni). Ukuwelda kufuneka kwenziwe ngokusebenzisa i-argon arc welding kwisiseko kunye ne-arc welding yesigqubuthelo. Amalungu e-Weld kufuneka avavanye i-100% ye-radiographic (RT) kunye nenqanaba lokupasa ≥ II ukukhusela ukuvuza.
Uyilo Lwemibhobho:
Ukuthambeka kwePipeline: Iumbhobho we-oyile yokubuyisela i-oyilekufuneka ibe ne-slope ≥ 3‰, ethambekele kwitanki yeoli okanye i-drain outlet ukukhusela ukuqokelela kwe-oyile yendawo kunye nokupheka. Ukuthambeka kombhobho wokuphuma kwe-oyile kungancitshiswa ukuya ku-≥ 1‰ ukuqinisekisa ukuhamba kakuhle kwe-oyile.
I-Exhaust kunye ne-Drainage: Fakela i-valve yokukhupha i-valve kwindawo ephezulu yombhobho (njengomphezulu wesithando okanye kwi-bend) ukukhusela ukuqokelela kwegesi kwinkqubo, enokubangela "ukuvalwa kwegesi" (ukushisa kwendawo). Faka i-valve ye-drain kwindawo ephantsi ukuze uququzelele ukucocwa rhoqo kokungcola kunye nokupheka. Gwema ukugoba okubukhali kunye nokutshintsha kobubanzi: Sebenzisa ukugoba okugobileyo (i-radius of curvature ≥ amaxesha ama-3 ububanzi bombhobho) kwiibhobho zombhobho; kuphephe ukugoba engile-engile. Sebenzisa i-concentric reducers xa utshintsha i-diameters ukuphepha utshintsho lwe-eccentric olunokuphazamisa ukuhamba kweoli kwaye kubangele ukufudumala kwendawo.
Uvavanyo lokutywinwa: Emva kokufakwa kombhobho, yenza uvavanyo loxinzelelo lwamanzi (uvavanyo loxinzelelo lwe-1.5 amaxesha oxinzelelo lokusebenza, gcina uxinzelelo lwemizuzu ye-30, akukho ukuvuza) okanye uvavanyo lwe-pneumatic (uxinzelelo lovavanyo lwe-1.15 amaxesha oxinzelelo lokusebenza, gcina uxinzelelo lweeyure ze-24, uxinzelelo lwehla ≤ 1%). Emva kokuqinisekisa ukuba akukho kuvuza, qhubeka ne-insulation.
I-Insulation: Imibhobho kunye nemizimba ye-furnace kufuneka ifakwe i-insulation (usebenzisa izinto zokugquma ezixhathisa ubushushu obuphezulu obufana noboya belitye kunye ne-aluminium silicate, kunye nobukhulu be-≥ 50mm). Gquma ngomaleko okhuselayo wentsimbi ukukhusela ukulahleka kobushushu kunye nokutsha. Umaleko wokugquma kufuneka uvalwe ngokuqinileyo ukukhusela amanzi emvula ukuba angangeni kwaye abangele ukusilela kokugquma. 3. Ukufakwa kweNkqubo yoMbane: Ukhuseleko kunye noLawulo oluchanekileyo
IiNgcaciso zeeNcingo: Ikhabhinethi yombane kufuneka ibekwe kude nobushushu kunye nemithombo yamanzi. Iintambo zamandla kunye nokulawula kufuneka zibekwe ngokwahlukeneyo (sebenzisa intambo ekwazi ukumelana nomlilo kwiintambo zombane). Iitheminali kufuneka zibotshelelwe ngokukhuselekileyo ukuthintela imidibaniso ekhululekileyo enokukhokelela kubushushu obugqithisileyo. Inkqubo yokumisa kufuneka ithembeke, kunye nokuchasana komhlaba ≤4Ω (kuquka ukuhlaliswa kwezixhobo ngokwawo kunye nekhabhinethi yombane).
IiMfuno zobungqina obuqhushumbayo: Kwi-oyile-i-oyile / igesiiibhoyila zeoyile ezishushu,izinto zombane ezikufutshane nesitshisi (ezifana neefeni kunye neevalvu zesolenoid) kufuneka zikhuseleke ukudubula (umzekelo, Ex dⅡBT4) ukunqanda iintlantsi ekubangeleni ugqabhuko-dubulo lwerhasi.
Ukujonga umgaqo wokulawula: Phambi kokugunyaziswa, qinisekisa iischematics zombane ukuqinisekisa ukuba ulawulo lobushushu, ukhuseleko loxinzelelo, kunye ne-alam zomgangatho wolwelo ophezulu kunye nophantsi zisebenza ngokufanelekileyo (umzekelo, ukuvala ngokuzenzekelayo kwe-oyile ye-thermal xa ubushushu obugqithisileyo busenzeka kunye nokuqaliswa kwesitshisi kungavunyelwanga xa umgangatho wolwelo uphantsi).
II. UkuKhomishana kweNkqubo: Qinisekisa uKhuseleko kwiiNqanaba
1. Ukugunyaziswa okubandayo (Akukho Ukufudumala)
Khangela ukunyanzeliswa kwePipeline: Gcwalisa inkqubo ngeoli ye-thermal (vula i-valve yokukhupha ukukhupha wonke umoya ngexesha lokuzaliswa) de inqanaba leoli lifike kwi-1 / 2-2 / 3 yetanki. Yiyeke ihlale iiyure ezingama-24 kwaye ihlole imibhobho kunye neentsimbi zokuvuza.
Uvavanyo lweNkqubo yokuThuthwa: Qala ipompo yokujikeleza kwaye ukhangele inqanaba lokusebenza ngoku kunye nenqanaba lengxolo (yangoku ≤ ixabiso elilinganisiweyo, ingxolo ≤ 85dB). Qinisekisa ukuba ioli ye-thermal ijikeleza kakuhle ngaphakathi kwenkqubo (chukumisa imibhobho ukuqinisekisa ukuba akukho ndawo ezibandayo ukuphepha ukuvala umoya).
Qinisekisa iMisebenzi yoLawulo: Linganisa iimpazamo ezifana nobushushu obugqithisileyo, uxinzelelo olugqithisileyo, kunye nenqanaba lolwelo oluphantsi ukuqinisekisa ukuba ii-alam kunye nemisebenzi yokuvalwa kongxamiseko isebenza ngokufanelekileyo.
2. Ukugunyaziswa kwe-oyile eshushu (uKunyuka kobushushu obuncinci)
Ukulawulwa kweqondo lokufudumeza: Ukunyuka kweqondo lokushisa lokuqala kufuneka kucothise ukunqanda ukufudumeza kwendawo kunye nokupheka kweoli ye-thermal. Iimfuno ezithile:
Ukushisa kwegumbi ukuya kwi-100 ° C: Izinga lokushisa ≤ 20 ° C / h (ukususa umswakama kwioli ye-thermal);
I-100 ° C ukuya kwi-200 ° C: Isantya sokufudumala ≤ 10 ° C / h (ukususa amacandelo okukhanya);
I-200 ° C kwiqondo lokushisa lokusebenza: Isantya sokufudumala ≤ 5 ° C / h (ukuzinzisa inkqubo).
Ukujongwa kweNkqubo: Ngethuba lenkqubo yokufudumeza, jonga ngokusondeleyo i-gauge ye-pressure gauge (ngokungaguquguquki okanye ukunyuka ngokukhawuleza) kunye ne-thermometer (kwiqondo lokushisa elifanayo kuwo onke amanqaku). Ukuba kukho nakuphi na ukungcangcazela kwemibhobho okanye okungaqhelekanga kobushushu (umzekelo, ukufudumeza kwendawo okungaphezulu kwe-10°C) kufunyenwe, ngoko nangoko vala iziko ukuze lihlolwe ukuphelisa nakuphi na ukuvaleka komoya okanye umqobo.
Ukukhuselwa kweGesi yeNitrojeni (OkoKhethayo): Ukuba ioli ye-thermal isetyenziswe kwiqondo lokushisa ≥ 300 ° C, kucetyiswa ukuba uqalise i-nitrogen (uxinzelelo oluncinci, i-0.02-0.05 MPa) kwi-tank yeoli ukukhusela i-oxidation ekudibaneni nomoya kunye nokwandisa ubomi bayo benkonzo.
