1. Isakhiwo sombhoshongo esigcwele
Isakhiwo sombhoshongo wamanzi ashisayo agcwele umbhoshongo ogcwele phama, isilinda wenziwe ngensimbi ye-manganese engu-16, uhlaka lokusekela ukupakisha kanye namapuleti ayishumi e-swirl enziwe ngensimbi engagqwali engama-304, ipayipi lokufafaza lamanzi ashisayo aphezulu embhoshongweni ogcwele wenziwe nge-carbon steel, kanye nesihlungi sensimbi engagqwali Izinto ezibonakalayo ziyinsimbi engagqwali engama-321. Ngemva kokusetshenziswa kombhoshongo wamanzi ashisayo agcwele, izinga lokushisa lengxenye engenhla yesithando somlilo esiphakathi nendawo lehla kakhulu. Ngemva kokuphuma kwegesi enamanzi amancane embhoshongweni ogcwele amanzi, amanzi angena esithandweni sokuguqula esimaphakathi, okwenza ukuba izinga lokushisa lomlilo lehle. Ngesikhathi kuhlolwa, kutholakale ukuthi ipayipi lokufutha lamanzi ashisayo agcwele ligqwalile, kanti isihlungi sensimbi engagqwali phezulu kombhoshongo bekuyi-Mesh nayo igqwalile kakhulu, ezinye izimbobo zemesh zigqwalile.
2. Izimbangela zokugqwala kombhoshongo ogcwele
Njengoba okuqukethwe komoya-mpilo embhoshongweni osuthisiwe kuphakeme kunalokho okusembhoshongweni wamanzi ashisayo, nakuba okuqukethwe okuphelele komoya-mpilo kugesi elincane lamanzi akuphakeme, inqubo yokugqwala kwensimbi ye-carbon esixazululweni esinamanzi ngokuyinhloko iwukuchithwa komoya-mpilo, okuncike ekushiseni nasekucindezelweni. Uma zombili ziphakeme, umphumela wokukhipha umoya-mpilo umkhulu. Okuqukethwe kwe-chloride ion esixazululweni esinamanzi nakho kuyisici esibalulekile ekugqwaleni. Njengoba i-chloride ion ingabhubhisa kalula ifilimu evikelayo endaweni yensimbi futhi isebenze indawo yensimbi, lapho ukugxila kufinyelela inani elithile, insimbi engagqwali ngeke imelane nokugqwala. Lesi futhi isizathu socingo lwensimbi engagqwali phezulu kombhoshongo ogcwele. Isihlungi sonakale kakhulu. Ukushintshashintsha kwengcindezi yokusebenza kanye nokwenyuka nokwehla okungazelelwe okuvamisile emishinini yezinga lokushisa, amapayipi, nokufakwa kwezingcindezi ezishintshanayo, ezingabangela ukugqwala kokukhathala.
3. Izinyathelo zokulwa nokugqwala kombhoshongo osuthekile
① Phakathi nenqubo yokukhiqiza igesi, lawula ngokuqinile okuqukethwe kwesibabule kugesi elingamanzi ukuze ugcine okuqukethwe kuphansi ngangokunokwenzeka. Ngesikhathi esifanayo, lawula umsebenzi we-desulfurization ukuze uqinisekise ukuthi okuqukethwe kwesulfure ku-semi-water gas ngemva kwe-desulfurization kuphansi.
② Amanzi ashisayo ajikelezayo asebenzisa amanzi athambile ane-desalted ukulawula izinga lamanzi ashisayo ajikelezayo, ahlaziye inani lamanzi ashisayo ajikelezayo njalo, futhi engeza inani elithile lamanzi e-ammonia emanzini ashisayo ajikelezayo ukuze kwandiswe inani lamanzi.
③ Qinisa ukuphambukisa kanye nokukhipha amanzi, khipha ngokushesha indle efakwe ohlelweni, futhi ugcwalise amanzi athambile afakwe usawoti ahlanzekile.
④ Miselela impahla yepayipi lokufafaza lamanzi ashisayo lombhoshongo wokugcwala ngo-304 kanye nezinto zokuhlunga zensimbi engagqwali ngo-304 ukuze kunwetshwe impilo yayo yesevisi nokuqinisekisa ukusebenza kwesikhathi eside kwesistimu.
⑤ Sebenzisa i-anti-corrosion coating. Ngenxa yokucindezela koshintsho oluphezulu nokushisa okuhambisanayo, upende ogcwele i-zinc we-inorganic kufanele lusetshenziswe ngoba unokumelana kahle namanzi, awesabi ukungena kwe-ion, unokumelana nokushisa okuphezulu, ushibhile, futhi kulula ukuwenza.
