Eqinisweni, noma ngabe i-othomathikhi ngokugcweleiyunithi yokushintsha ukushisanoma ezinye izisetshenziswa zemishini, ukuhlanza kuyingxenye ebaluleke kakhulu yokunakekelwa.Ukuhlanza amayunithi okushintshanisa ukushisa okungagadiwe akukhawulelwe ekuhlanzeni ingaphezulu lempahla.Ingaphakathi leisishintshi sokushisa esizenzakalelayo ngokugcweleIyunithi nayo idinga ukuhlanzwa.Izindlela ezintathu ezilandelayo zivame ukusetshenziswa lapho kuhlanzwa i-PLC ngokuzenzakalelayo amayunithi okushintshanisa ukushisa.
I-Countercurrent flushing method: Ivamise ukusetshenziswa ngesikhathi sokusebenza noma{0}}isikhathi sokupaka isikhathi esifushane, futhi idivayisi ayidingi ukuhlakazwa. Nokho, ulayini wokudlula ophikisanayo kufanele ufakwe ngaphambili{2}}esisetshenziswa. Le ndlela iwusizo kakhulu uma isikali singesikhulu.
{0}Indlela yokugeza ijethi yamanzi anomfutho ophezulu:Izinhloko zezibhamu zamanzi ezishintshayo ezihlukene zingakhethelwa izishintshi zokushisa ezihlukene; zingaqina.Iyakwazi futhi nezimo, ngokucindezela okulungiseka ngokukhululekile ukusuka ku-10MPa ukuya ku-200MPa.Ukuhlanzwa kwamanzi anomfutho ophakeme{5}}kufanelekile ukuhlanza kokubili phakathi kwamapayipi, amapayipi angaphakathi, kanye negobolondo. Amajethi{7}anamandla aphezulu asebenza kahle futhi asetshenziswa kabanzi ekushiseni izishintshi zokushisa.
Indlela yokuhlanza amakhemikhali:Vala amavalvu ukuze apholise amanzi angenayo noma aphume ku-condenser, futhi usebenzise ishubhu le-thermometer, ishubhu lokukala umfutho, noma ipayipi lokudonsa amanzi ukuze uxhume iphampu evimbela ukugqwala kanye nethangi lokuxuba uketshezi ukuze wenze isistimu encane yomjikelezo yokuhlanza okujikelezayo. Okokuqala, engeza i-pickling corrosion inhibitor. Le ejenti iyi-copper corrosion inhibitor ekhethekile. Inamathela odongeni lwensimbi lwangaphakathi lwecondenser ukuvimbela i-asidi ukuthi ingasabelani nensimbi.Ukwengeza i-ejenti yokuhlanza i-asidi eqinile isetshenziselwa ukuhlanza i-limescale, ikakhulukazi eyakhiwe nge-calcium carbonate.I-ejenti yokuhlanza iyi-asidi eqinile eyinkimbinkimbi, i-crystal emhlophe, engagqwali{6}ezinsimbi futhi iyi-asidi ebuthakathaka; inani le-ejenti yokuhlanza elisetshenzisiwe lincike enanini lesikali esakhiwe emishinini.Engeza isikhiphi sesikali (uyazikhethela). Uma i-condenser inongqimba obukhulu besikali, isikhiphi sesikali sidinga ukwengezwa.Sikhuthaza ukuhlakazeka okusheshayo kwemikhiqizo ekhiqizwe ngemva kokusabela kwesikali emanzini, ngaleyo ndlela kusheshiswe ukusabela kwesikali esijulile.Ukwengeza i-agent engathathi hlangothi futhi edlulayo kunciphisa i-asidi esele ngemva kokuhlanza amakhemikhali we-condenser, ukuvimbela i-oxidation yendawo yensimbi kanye nokwakheka kwe-rust yesibili.
Ngakho-ke, abanye abantu bangase babuze, kufanele kuhlanzwe kangaki isishintshi sokushisa esizenzakalelayo? empeleni,Umjikelezo wokuhlanza wamayunithi okushintshanisa okushisa ahlakaniphile awulungisiwe.Izici ezifana nezinga lokukala kusishintshi sokushisa, izimo zokusebenza kwemishini, ukusebenza kahle kokushintshisana kokushisa, kanye nokukhiqizwa kokusetshenziswa kwamanzi kudingeka kubhekwe ngokucophelela.Ngokuvamile, uma okokusebenza kusebenza ngokuzinzile futhi ukusebenza kahle kokushintshisana kokushisa kungehli kakhulu, kungahlanzwa njalo ngemva kwezinyanga eziyisithupha kuya onyakeni. amayunithi okushintshanisa ukushisa okushisisayo ayimishini yokusebenza ngokuqhubekayo, ngakho-ke kudingeka ahlolwe futhi ahlanzwe njalo ukuze kuqinisekiswe ukusebenza kwawo okuvamile nokusebenza kahle kokushintshanisa ukushisa.
