Inkampani Yamathangi Amanzi Angcolile E-Enamel Isikhungo Se-Enamel Sokugcina Amanzi Angcolile Ezimbonini
Amathangi e-enamel effluent agcina i-effluent yezimboni esitsheni esivikelwe ngengilazi hhayi ngopende. I-Center Enamel incibilikisa i-enamel kumapaneli e-carbon steel ku-820 kuya ku-930 °C, ikhiqize ungqimba lwe-enamel olungu-0.25 kuya ku-0.45 mm olukalwa ngaphezu kwe-3,450 N/cm², luhlolwe nge-spark ku-1500 V DC kulo lonke iphaneli, futhi lubekezelela i-pH 1 kuya ku-14. Amapaneli angaba ngu-1.2 m ububanzi, aboshwe ngamabhawodi e-8.8-grade kanye nama-EPDM gaskets, ngakho ithangi lihlangana ngokushesha esizeni futhi lingandiswa kamuva. Ekusebenziseni i-effluent, i-enamel isusa umjikelezo wokuphinda kufakwe ungqimba ngaphakathi kanye nokugqobhoza kokugqwala okulandela lokho, ngesikhathi sokuphila esiklanyelwe iminyaka engu-30 noma ngaphezulu ekugcineni komoya.
I-efluent yezimboni ayithetheleli ngendlela amanzi okucubungula angenza ngayo. Ukwakheka kwayo kuyashintsha ngokushintsha kwesikhathi, amanzi okuhlanza afika ngaphandle kwesixwayiso, futhi imithetho embonini okufanele iyihlangabezane ibhalwe ngokumelene nokugxila okufanele kugcinwe phakathi kwamasampuli. Ithangi lensimbi yekhabhoni elifakwe i-organic coating kulo msebenzi ngokuvamile lihluleka emaphethelweni, bese kugqwalasela ukugqwala ngaphansi kwe-coating, bese i-coating ikhulula ngamashidi. Amaqembu afuna ithangi le-efluent le-enamel lokugcina i-efluent yezimboni ngokuvamile aqhathanisa leyo ndlela yokuhluleka nesithombe sezingilazi esihlanganisiwe. Ukuqhathanisa kufanele kwenziwe kahle, ngoba impendulo efanele incike ekhemistri, izinga lokushisa kanye nokufinyelela okunakho isiza ukulungisa. Uhlu olufushane luyinkampani yamathangi e-efluent e-enamel i-Center Enamel yokugcina i-efluent yezimboni kuphela lapho ingilazi ihlanganiswe nensimbi ku-820 kuya ku-930 °C esikhundleni sokuthi kufakwe i-organic lining phezu kwayo.
Ubuso be-enamel obuhlanganisiwe ekusebenzeni kwamanzi angcolile
I-Fusion isusa i-coating interface evamise ukugqwala. I-enamel powder isetshenziswa ku-steel panel elungisiwe futhi ishiselwa phakathi kuka-820 no-930 °C, ukuze ingilazi nensimbi kube yinto eyodwa ehlanganisiwe esikhundleni sezinto ezimbili ezicindezelwe ndawonye. Isendlalelo se-enamel esiqediwe singu-0.25 kuya ku-0.45 mm ubukhulu futhi silinganiswa ngaphezu kuka-3,450 N/cm² ngokumelene nokugoba nokucindezelwa, ngobukhulu obungaphansi kuka-Ra 0.8 µm obumelana nokunqwabelana kwemfucuza futhi kugezwe kalula. Akukho primer, akukho solvent layer futhi akukho adhesion amanzi angangena ngemuva kwayo, okuyisizathu esivamile sokuthi i-organic lining ngaphakathi kwethangi le-effluent iqale ukubhobozeka phakathi neminyaka embalwa.
Okusele njengendlela yokwehluleka kwangempela ukuchayeka emaphethelweni. Iphaneli esikwe emlonyeni noma eflangini iveza insimbi engenalutho emaphethelweni engilazi, futhi ukuqhekeka kwalelo phethelo yilapho inqubo iqala khona. Izindlela ezintathu ziyakunciphisa: umphetho wephaneli uyelashwa efektri, amaphaneli aphathwa ngezinto zokuphakamisa esikhundleni sokuhudula, futhi ukuma kwephaneli kugcinwa kufana ukusuka kwiringi kuya kwiringi ukuze imiphetho elashiwe iqondane lapho kulula ukuyivikela nokuyihlola.
Umkhakha wamakhemikhali kanye nombuzo we-sulfide
Ukushintshashintsha kwe-pH yamanzi angcolile yikhona okuyisizathu esiyinhloko sokukhetha. I-enamel ihlanganisa lonke uhla olusuka ku-pH 1 kuye ku-14, ngakho umgqomo ungamukela umfudlana waseshumini ongathathi hlangothi kanye neqoqo lokubhalisa eline-asidi noma i-caustic ngaphandle kokushintsha ulwelwesi. Leyo mpawu eyodwa iyona eyenza i-enamel ibe yikho okuzenzakalelayo ezitshalweni ezithola imifudlana evela ezindaweni eziningi zokusebenza ezinqubo ezihlukene. Lapho umfudlana uthwala i-hydrogen sulfide, njengamanzi angcolile okudla acebile ngamaprotheni noma umfudlana wesikhumba, i-enamel ibekezelela i-sulfide kulo lonke uhla lwayo lwe-pH, ngakho umgqomo ngokwawo awuyona ingxenye ebekelayo umkhawulo. Isidingo sokukhipha i-sulfur sisezindaweni ezingezansi, ekusingatheni igesi kanye nasemishinini yokushisa, futhi kufanele kulinganiswe ngokwesilinganiso esiphezulu hhayi ngokwesilinganiso esimaphakathi.
Izinga lokushisa ne-chloride yizinto ezimbili ezingashintsha impendulo. Umfudlana oshisayo unciphisa ithuba kunoma yiluphi ugqinsi, futhi okuqukethwe okuphezulu kwe-chloride kuholela abanye abasebenzi ku-316L stainless noma into ephindwe kabili ezingxenyeni ezimanzi, ikakhulukazi eduze kwemithungo nezindawo zokushisa okuphezulu. Lezo yizimo okufanele ziphakanyiswe esigabeni sokukhetha hhayi ngemuva kokuba amaphaneli e-odiwe.
Ukwakhiwa okuboshiwe kwezitshalo zendle
Ifomethi eboshiwe ilingana nezitshalo ezakhiwe futhi zandiswa ngezigaba. Amaphaneli acishe abe ngu-1.2 m ububanzi alungiselelwa efektri, afakwe i-enamel, ahlolwe nge-spark futhi abalwe, bese ethunyelwa ngamakhontena noma nge-breakbulk futhi ahlanganiswe ngamabhawodi e-8.8-grade kanye nama-EPDM gaskets endaweni. Esikhungweni sezimboni noma endaweni ekhona yomsebenzi, lokho kusho ukuthi akukho ukushisela kwegobolondo, iwindi le-crane elincane, kanye nokufakwa okungasebenza eduze kwesitshalo esiphilayo. Futhi kunikeza indlela ecacile yokwandisa: izindandatho ezengeziwe zinyusa umthamo wethangi elilodwa, noma ithangi lesibili lengezwa eceleni kwalo, kusetshenziswa isisekelo esifanayo esisele.
Izinto ezimbili zesayithi zinquma ukuthi ukuhlangana okuboshiwe kuhlala kungavuzi iminyaka. Okokuqala yisisekelo: i-ring beam noma isisekelo sikakhonkolo esinomehluko wokuhlala ovunyelwe ochazwe kumklamo. Okwesibili yi-gasket: i-EPDM iyinto evamile ye-gasket yamanzi namanzi angcolile, ihambisana nebanga elibanzi le-pH futhi kulula ukuyishintsha lapho kuvalwa okulandelayo, futhi isimo sobuso be-flange kuphaneli sibaluleke kakhulu kune-gasket iyodwa.
