Izinto Zokugcina Uwoyela Wokupheka Wensimbi Engagqwali, Ukuqedwa Kanye Nokukhipha Umoya
Ukugcinwa kwamafutha okupheka kuwumsebenzi wekhwalithi yomkhiqizo njengoba kunjalo nowokwakheka. Ithangi lensimbi engagqwali iyakhethwa ngoba amafutha athinta indawo yensimbi okumelwe ingadluli kuyo, futhi i-304 ngokuvamile yanele kumafutha adliwayo kuyilapho i-316L iyimpendulo lapho kukhona usawoti, i-asidi noma uhlelo olunzima lokuhlanza. Izinto ezimbili zokuklama ezinquma impilo yokusebenza iwukuphela kwendawo kanye ne-gasket: ingaphakathi elibushelelezi, elihlanjululwe kahle elihlanza ngokwezicaciso, kanye nenhlanganisela ye-gasket eqinisekisiwe ngokumelene namafutha kanye ne-ejenti yokuhlanza ezingeni lokushisa. Isikhala somhwamuko, isiphephetha-moya kanye nelungiselelo lokushisa kuvala okunye.
Ithangi lokugcina uwoyela wokupheka kufanele libambe amafutha noma uwoyela ngekhwalithi ezokwahlulelwa ngesimiso somkhiqizo, futhi kufanele limelane nomjikelezo wokuhlanza oshisa kakhulu futhi onamandla kakhulu kunemeko yokugcina ngokwayo. Yenza i-alloy ibe ngendlela efanele futhi umkhiqizo uhlale uhlanzekile; yenza ukuqedwa noma i-gasket ibe ngendlela engafanele futhi ithangi libe yisizathu sokuthi iqoqo lilenqatshwe. Izindlela eziningi zokwehluleka lapha zithule: umklwebho obamba uwoyela ogxumile, i-gasket evuvukalayo futhi econsayo, indawo yomhwamuko ejikijela amanzi kuqweqwe olungaphezu komugqa woketshezi, ukulahlekelwa ukushisa okuvumela amafutha ukuthi aqale ukuhlukaniseka eduze kodonga. Le ndatshana ihlanganisa into, ukuqedwa, i-gasket kanye nendawo yomhwamuko.
Ingxubevange kanye necala lamafutha adliwayo
I-304 stainless iyimpendulo evamile kumafutha okupheka; i-316L ithola indawo yayo kuphela lapho usawoti noma i-asidi kungena khona enqubeni. Ukuthintana namafutha asezingeni lokudla emshinini wokugaya, embonini yotshwala, embonini yokudla okulula noma eqenjini lezindawo zokudlela kusebenza kahle nge-304 ene-2B noma i-polished finish, engadluli futhi elula ukuhlanza. I-316L iba yisicaciso esifanele lapho amafutha efakwa usawoti noma enziwa flavour nge-usawoti, lapho kukhona isithako se-asidi, lapho kusetshenziswa khona i-caustic eqinile noma i-asidi yokuhlanza endaweni (clean-in-place) njalo, noma lapho imboni isendaweni ene-chloride efinyelela ingaphandle. Okuqukethwe yi-molybdenum yikho okubhekana ne-chloride, futhi kufanele kucaciswe ngamabomu kunokuba kwenziwe ngomkhuba.
Ukubhekisisa okuvelayo uma kuqhathaniswa ne-glass-fused-to-steel kufanele kwenziwe ngobuqotho. Iphaneli ye-glass-fused-to-steel ithwala indawo ye-enamel ehlanganiswe ku-820–930 °C ibe ngu-0.25–0.45 mm, engasebenzi ku-pH 1–14, enobukhulu obungaphansi kuka-Ra 0.8 µm, futhi ivamise ukuba yinani elingcono emthwalweni omkhulu. I-stainless iyawina lapha lapho inqubo idinga indawo yensimbi, lapho ithangi kufanele lishiswe noma lifakwe i-jacket, lapho i-geometry ingajwayelekile, noma lapho uwoyela uwumkhiqizo wenani eliphezulu onomkhawulo oqinile wokufuduka. Kuleli banga lomthwalo, ithangi le-stainless libiza izikhathi ezimbalwa okulingana ne-enamel nge-cubic metre ngayinye, ngakho-ke isinqumo kufanele sibhalwe nesizathu.
Ukuqedwa, i-passivation kanye nokuhlanjululwa
Ukuphela yikho okubonwa uwoyela, futhi indawo emahhadlahhadla kancane kancane iba yindawo yokugcina izinto ezihlala phansi. Ingaphakathi le-2B noma elikhazimulisiwe elinomumo wokushisela obushelelezi endaweni yokuxhumana linikeza ifilimu kawoyela into engayibambayo, okuyikho okwenza ukuhlanza phakathi kwemikhankaso yomkhiqizo kube nokwenzeka. I-passivation ngemva kokwakhiwa isusa i-iron ekhululekile ebusweni futhi ibuyisela ungqimba lwe-chromium oxide; ngaphandle kwerekhodi, ukuphela okuhle kungase kuconsa amabala okugqwala kungene emkhiqizweni wokudla. Ukugezwa kokugcina nokuhlolwa kwangaphakathi kufanele kube sephaketheni lokwamukela kanye nesitifiketi sempahla.
Ukuhlanza kuyingxenye yesibili. Umugqa wamafutha okupheka ohlanzwa nge-caustic noma nge-asidi udinga ilungiselelo lokuhlanza endaweni (clean-in-place) elinendandatho yokufafaza emboza yonke ingaphakathi kuhlanganise nokudlula kophahla kuya kuqweqwe, ngaphandle kwemilenze efile, kanye nomsele owodwa ophansi ukuze kungabi nanhlanhlatha ehlala emgodini wamanzi. Lapho amafutha ashiselwa khona, ijazi lokushisa noma ikhoyili iphakamisa umbuzo wesibili: indawo yokushisa kumele ihlanzeke, ngoba amafutha ashile anamathele odongeni lokushisa angumthombo ojwayelekile wephunga elibolile kusiqu esilandelayo. Amakhoyili amancane ensimbi engagqwali noma ijazi eliseqweqweni kunikeza izinhlobo ezahlukene zokuhlanza futhi ukukhetha kungokwakho ekwakhiweni.
Ama-gasket, ama-nozzle kanye nendawo yomhwamuko
I-gasket yasechwebeni ngalinye iyingxenye emininingwane eminingi ekhohlwayo, futhi uwoyela kanye ne-ejenti yokuhlanza inhlanganisela enzima. I-gasket evuvukala kuwoyela oshisayo noma ku-caustic izohlanekela iphutha futhi iconsa, kanti leyo engena emkhiqizweni iwukwehluleka kwekhwalithi. Inhlanganisela kufanele iqinisekiswe ngokumelene nawo womabili uwoyela ogciniwe kanye ne-ejenti yokuhlanza ezingeni lokushisa lokuhlanza, hhayi ezingeni lokushisa legumbi kuphela. Ethangini lensimbi engagqwali eliboshwe ngamabhawudi, isihlanganisi esine-gasket siyahlolwa futhi singashintshwa, okuyinzuzo; ethangini elishiselwe, ama-gasket omgwaqo womuntu kanye nesango kuseyizingxenye ezinyakazayo kuphela futhi kufanele zihlolwe ngendlela efanayo.
Isikhala somhwamuko esingaphezu kawoyela yilapho kwakheka khona ukujiya: uwoyela ofudumele ophefumulela esikhaleni sekhanda esipholile ubeka amanzi egobolondweni elingaphezu komugqa woketshezi, futhi amanzi esendaweni enamafutha ayisiqalo sokuhlakazeka kwamanzi kanye ne-asidi yamafutha amahhala. Izimpendulo ezingokoqobo iwophahla oluvikelwe ngomhwamuko olugqinsiwe, umfutho ohlungiwe kanye nokukhululeka kwe-vacuum okulinganiswe nokuphefumula okushisayo kanye nezinga lokugcwalisa, futhi — lapho uwoyela ushisiswa khona noma isitshalo sisendaweni enomswakama — isikhala somhwamuko esigcinwa somile ngomklamo hhayi ngokukhipha umoya ekamelweni. Uphahla olujiya kuwoyela luyinkinga yomkhiqizo, hhayi eyokunakekela.
