I-centrifuge ye-decanter yesigaba esi-2 yahluke njani kwi-decanter yesigaba esi-3?

Intshayelelo

Kwihlabathi lobuchwepheshe bokwahlukanisa izimboni, ii-decanter centrifuges zibe yinxalenye ebalulekileyo yeenkqubo ezininzi zokwenza imveliso. Ukukwazi kwazo ukwahlula ulwelo kunye nezinto eziqinileyo ngokufanelekileyo kuzenze zaba lukhetho oludumileyo kumashishini afana nokutya neziselo, amayeza, unyango lwamanzi amdaka, nokunye. Kukho iintlobo ezahlukeneyo zee-decanter centrifuges ezikhoyo, apho i-decanter yesigaba esi-2 kunye ne-decanter yesigaba esi-3 zibe zezona ntlobo zimbini zisetyenziswa kakhulu. Kweli nqaku, siza kuhlola umahluko phakathi kwezi ntlobo zimbini zee-decanter centrifuges kunye nezicelo ezithile apho nganye ifaneleka khona.

I-Centrifuge ye-Decanter yeSigaba esi-2

I-centrifuge ye-decanter enezigaba ezibini, njengoko igama lisitsho, yenzelwe ukwahlula umxube wesondlo ube ziinqanaba ezimbini ezahlukeneyo: isigaba solwelo (okanye esimanzi) kunye nesigaba esiqinileyo. Umxube wesondlo ungeniswa kwisitya esijikelezayo se-centrifuge, apho ukujikeleza ngesantya esiphezulu kubangela ukuba izinto eziqinileyo zihlale eludongeni lwesitya ngelixa isigaba solwelo esikhaphukhaphu senza umaleko ojikelezayo ojikeleze ikhekhe eliqinileyo. Ulwelo olucacileyo lukhutshwa phezu kwee-weirs ezihlengahlengiswayo kwicala elichaseneyo lesitya, ngelixa izinto eziqinileyo zikhutshwa kwisitya ngumthumeli wezikrufu.

Inzuzo ephambili ye-centrifuge ye-decanter yezigaba ezi-2 kukuba lula kwayo. Ngenxa yokuba iindawo ezimbalwa ezishukumayo kunye nenkqubo yokwahlulahlula elula, i-decanter yezigaba ezi-2 kulula ukuyisebenzisa nokuyigcina. Ikwasebenza kakuhle ekususeni amanzi nasekuqiniseni, nto leyo eyenza ukuba ifaneleke kumashishini apho injongo ephambili ikukwahlula izinto eziqinileyo kwizinto ezimanzi.

Enye yezinto ezingalunganga nge-decanter yesigaba esi-2, nangona kunjalo, kukungakwazi kwayo ukwahlula izigaba ezimbini ezahlukeneyo zolwelo. Oku kuthetha ukuba ukuba umxube wesondlo uqulethe ulwelo olungenakuxubana ezimbini, njengeoyile namanzi, i-decanter yesigaba esi-2 isenokungabi lolona khetho lufanelekileyo. Kule meko, i-centrifuge yesigaba esi-3 ingaba lolona khetho lufanelekileyo.

I-Centrifuge ye-Decanter yeSigaba esi-3

Ngokungafaniyo ne-decanter yezigaba ezi-2, i-centrifuge ye-decanter yezigaba ezi-3 iyakwazi ukwahlula umxube we-feed ibe ziizigaba ezintathu ezahlukeneyo: isigaba solwelo, isigaba solwelo esinzima, kunye nesigaba esiqinileyo. Oku kufezekiswa ngokongeza idama elihlengahlengiswayo ngaphakathi kwisitya se-centrifuge, esivumela ukuqokelelwa kunye nokukhutshwa ngokuzimeleyo kwezi zigaba zimbini zolwelo.

Ukukwazi ukwahlula izigaba ezimbini zolwelo ezingadibaniyo omnye komnye kwenza i-decanter yezigaba ezi-3 ifaneleke kakhulu kwizicelo apho ukubuyiswa kwezinto ezixabisekileyo kubaluleke kakhulu. Umzekelo, kwishishini leoyile negesi, i-decanter yezigaba ezi-3 ingasetyenziselwa ukwahlula ioyile ekrwada kwiindawo zayo, okuvumela ukubuyiswa kweoyile kunye namanzi akhoyo kumxube wesondlo. Oku kunokukhokelela ekongeni iindleko ezinkulu kunye neenzuzo zokusingqongileyo, njengoko amanzi afunyenweyo anokusetyenziswa kwakhona okanye aphathwe ngokufanelekileyo.

Ukongeza kwisakhono sayo sokwahlula izigaba ezibini zolwelo, i-centrifuge ye-decanter yezigaba ezi-3 ikwabonelela ngesakhono esifanayo sokukhupha amanzi kunye nokwandisa njenge-decanter yezigaba ezi-2. Oku kuyenza ibe lukhetho oluguquguqukayo nolusebenzayo kwiintlobo ngeentlobo zezicelo kumashishini ahlukeneyo.

Imigaqo Yokusebenza

Imigaqo yokusebenza ye-centrifuges ye-decanter yesigaba esi-2 kunye ne-3-phase isekelwe kwingcamango efanayo esisiseko yokwahlulwa kwamandla adonsela phantsi. Nangona kunjalo, iimpawu ezithile zoyilo lohlobo ngalunye lwe-centrifuge zivumela ukwahlulwa ngokufanelekileyo kwezigaba ezahlukeneyo ngaphakathi komxube we-feed.

Kwi-decanter enezigaba ezi-2, umxube wokutya ufakwa kwisitya esijikelezayo ngetyhubhu yokungena engashukumiyo, apho ukhawuleziswa kwisantya sesitya. Njengoko umxube ungena kwisitya, amandla aphezulu e-centrifugal asetyenziswa kwi-solids abangela ukuba zihlale eludongeni lwesitya, zenze ikeyiki eqinileyo. Ulwelo olucacileyo lukhutshwa phezu kwee-weirs kwicala elichaseneyo lesitya, ngelixa i-solids ikhutshwa kwisitya nge-screw conveyor.

Umgaqo wokusebenza kwe-decanter yezigaba ezi-3 ufana nowe-decanter yezigaba ezi-2, kunye namandla ongezelelweyo okukhupha ulwelo oluhlengahlengiswayo. Xa umxube wesondlo ungeniswa kwisitya esijikelezayo, isigaba solwelo esinzima sijoliswa eludongeni lwangaphakathi lwesitya ngedama elihlengahlengiswayo, ngelixa isigaba solwelo esikhaphukhaphu senza umaleko ojikelezileyo. Izinto eziqinileyo zihlala eludongeni lwesitya njengakwi-decanter yezigaba ezi-2, kwaye ulwelo olucacisiweyo lukhutshwa phezu kweendawo zokulahla ulwelo, njengakwi-decanter yezigaba ezi-2.

Idama elihlengahlengiswayo kwi-decanter enama-phase ama-3 livumela ulawulo oluzimeleyo lokukhupha amanzi kwi-phase ezimbini zolwelo, okuvumela ukwahlulahlula ama-phase amabini ahlukeneyo olwelo. Olu phawu lubeka i-decanter enama-phase ama-3 yahlukile kwi-counterpart yayo enama-phase ama-2 kwaye lenza ukuba ibe lukhetho oluguquguqukayo ngakumbi kwiindlela ezithile zokusebenza.

Izicelo

Ukukhetha phakathi kwe-centrifuge ye-decanter yesigaba esi-2 kunye ne-3-phase kuxhomekeke kwiimfuno ezithile zesicelo esikhoyo. Uhlobo ngalunye lwe-centrifuge lunezibonelelo zalo kunye nezakhono zalo ezizodwa, nto leyo eyenza ukuba ifaneleke kwiinkqubo ezahlukeneyo zoshishino.

I-centrifuge ye-decanter enezigaba ezibini ifanelekile kakhulu kwizicelo apho injongo ephambili ikukukhupha amanzi nokujiyisa umxube wokutya, nto leyo ebangela ukwahlulwa kwesigaba esiqinileyo kwisigaba solwelo. Oku kwenza ukuba ibe lukhetho oludumileyo kumashishini afana nonyango lwamanzi amdaka, imigodi, nokutya neziselo, apho ukubuyiswa kwezinto ezixabisekileyo kungeyiyo inkxalabo ephambili. Ukulula koyilo kunye nokusebenza kwayo kwenza i-decanter enezigaba ezibini ibe lukhetho olunomtsalane kumashishini anolwazi oluncinci kubuchwepheshe be-centrifuge.

Ngokwahlukileyo koko, i-centrifuge ye-decanter enama-phase amathathu ilungele ukusetyenziswa apho ukubuyiswa kwezigaba ezimbini ezahlukeneyo zolwelo kumxube wesondlo kuyinto ephambili. Oku kwenza ukuba ibe lukhetho olufanelekileyo kumashishini afana neoyile negesi, ukucubungula iikhemikhali, kunye nokulungiswa kwendalo, apho ukubuyiswa kwezinto ezixabisekileyo kunokukhokelela ekongeni iindleko ezinkulu kunye neenzuzo kwindalo. Ukukwazi ukulawula ngokuzimeleyo ukukhutshwa kwezigaba ezimbini zolwelo kuvumela ukuguquguquka okukhulu kunye nokusebenza kakuhle kwezi ntlobo zezicelo.

Isiphelo

Ukuqukumbela, ukhetho phakathi kwe-centrifuge ye-decanter yesigaba esi-2 kunye ne-3-phase luxhomekeke kwiimfuno ezithile zesicelo esikhoyo. Zombini ezi ntlobo ze-centrifuge zibonelela ngeenzuzo zazo ezizodwa kunye nemigaqo yokusebenza, nto leyo ezenza zifaneleke kwiinkqubo ezahlukeneyo zoshishino. Ngelixa i-decanter yesigaba esi-2 ifanelekile kwizicelo apho injongo ephambili kukwahlula isigaba esiqinileyo kwisigaba solwelo, i-decanter yesigaba esi-3 ifanelekile kwizicelo apho ukubuyiselwa kwezigaba ezimbini ezahlukeneyo zolwelo kumxube wesondlo kuyinto ephambili.

Ekugqibeleni, isigqibo sokusebenzisa i-centrifuge ye-decanter yesigaba esi-2 okanye esi-3 kufuneka sisekelwe ekuqondeni ngokupheleleyo iimfuno kunye neenjongo zesicelo, kunye nobuchule kunye nemida yohlobo ngalunye lwe-centrifuge. Ngokuqwalasela ngononophelo ezi zinto, abavelisi kunye nabaqhubi banokuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle kweenkqubo zabo zokwahlula, okukhokelela ekuphuculweni komgangatho wemveliso, ukwanda kwemveliso, kunye neendleko zokusebenza eziphantsi.
