Inqubo yokwelapha ukushisa kwensimbi ngokuvamile ihlanganisa izinqubo ezintathu: ukushisa, ukufudumala, kanye nokupholisa. Ngezinye izikhathi kunezinqubo ezimbili kuphela: ukushisa kanye nokupholisa. Lezi zinqubo zixhumene futhi azikwazi ukuphazanyiswa.
1. Ukushisa
Ukushisa kungenye yezinqubo ezibalulekile zokwelashwa kokushisa. Kunezindlela eziningi zokushisa zokwelapha ukushisa kwensimbi. Eyokuqala kwakuwukusebenzisa amalahle namalahle njengomthombo wokushisa, bese kusetshenziswa uphethiloli oluketshezi nowegesi. Ukusetshenziswa kukagesi kwenza ukushisa kube lula ukulawula futhi akunakungcola kwemvelo. Le mithombo yokushisa ingasetshenziswa ekufudumaleni okuqondile, noma ekufudumaleni okungaqondile ngosawoti oncibilikisiwe noma insimbi, noma ngisho nezinhlayiya ezintantayo.
Uma insimbi ishiswa, umsebenzi uvulwa emoyeni, futhi i-oxidation kanye ne-decarburization zivame ukwenzeka (okungukuthi, okuqukethwe kwekhabhoni ebusweni bengxenye yensimbi kuyancishiswa), okunomthelela omubi kakhulu ezimpahleni zobuso bezingxenye ngemva kokwelashwa kokushisa. Ngakho-ke, izinsimbi ngokuvamile kufanele zishiswe emoyeni olawulwayo noma emoyeni ovikelayo, kusawoti oncibilikisiwe, kanye nase-vacuum. Ukushisa okuvikelayo kungenziwa futhi ngezindlela zokumboza noma zokupakisha.
Izinga lokushisa lokushisa lingenye yezindlela ezibalulekile zenqubo yokwelapha ukushisa. Ukukhetha nokulawula izinga lokushisa lokushisa kuyindaba eyinhloko ukuqinisekisa ikhwalithi yokwelashwa kokushisa. Izinga lokushisa lokushisa liyahlukahluka kuye ngokuthi insimbi icutshungulwa kanjani kanye nenhloso yokwelashwa kokushisa, kodwa ngokuvamile lishiswa libe ngaphezu kwezinga lokushisa elithile lokuguqulwa ukuze kutholakale isakhiwo sokushisa okuphezulu. Ngaphezu kwalokho, ukuguqulwa kudinga isikhathi esithile. Ngakho-ke, lapho ubuso bensimbi bufika ezingeni lokushisa lokushisa elidingekayo, kumele bugcinwe kuleli zinga lokushisa isikhathi esithile ukuze kwenziwe amazinga okushisa angaphakathi nangaphandle ahambisane futhi ukuguqulwa kwesakhiwo esincane kuphelele. Lesi sikhathi sibizwa ngokuthi isikhathi sokubamba. Uma usebenzisa ukwelashwa kokushisa okunamandla aphezulu kanye nokushisa okuphezulu, isivinini sokushisa sishesha kakhulu futhi ngokuvamile asikho isikhathi sokubamba, kuyilapho isikhathi sokubamba sokwelashwa kokushisa kwamakhemikhali sivame ukuba side.
2. Ukupholisa
Ukupholisa nakho kuyisinyathelo esibalulekile enkambisweni yokwelapha ukushisa. Izindlela zokupholisa ziyahlukahluka kuye ngenqubo, ikakhulukazi zilawula izinga lokupholisa. Ngokuvamile, ukupholisa kunezinga lokupholisa elihamba kancane, ukuvuselela kunezinga lokupholisa elisheshayo, kanti ukucima kunezinga lokupholisa elisheshayo. Kodwa-ke, kunezidingo ezahlukene ngenxa yezinhlobo ezahlukene zensimbi. Isibonelo, insimbi eqinile emoyeni ingaqiniswa ngesilinganiso esifanayo sokupholisa nesokuvuselela.
