Ungachaza umahluko ophambili phakathi kwe-decanter yezigaba ezi-2 kunye ne-decanter yezigaba ezi-3?

Xa kufikwa ekucutshungulweni kwezinto ezimanzi kwimizi-mveliso, ii-decanters zizixhobo ezibalulekileyo zokwahlula izinto eziqinileyo kwizinto ezimanzi. Ii-decanters ziyafumaneka ngeendlela ezahlukeneyo, nganye yenzelwe ukuhambelana neemfuno ezahlukeneyo zokucubungula. Phakathi kweendlela ezininzi ezikhoyo, i-decanter yesigaba sesi-2 kunye ne-decanter yesigaba sesi-3 zikhetho ezimbini ezidumileyo. Kweli nqaku, siza kuhlola umahluko ophambili phakathi kwezi ntlobo zimbini zee-decanters, iimpawu zazo ezizodwa, kunye nokusetyenziswa kwazo kwiinkqubo zokwahlulahlula ulwelo-oluqinileyo.

Isivalo seSigaba esi-2

I-decanter yesigaba sesi-2, eyaziwa ngokuba yi-decanter yesigaba sesi-2, luhlobo lwe-centrifuge eyenzelwe ukwahlula ulwelo olungenamxube olune-densities ezahlukeneyo, okanye ukwahlula amasuntswana aqinileyo kulwelo. Uyilo lwe-decanter yesigaba sesi-2 luquka isitya esisilinda esinesiphelo esikhonkrithi. Isitya sijikeleza ngesantya esiphezulu, senza amandla e-centrifugal ahlula ulwelo kunye nesigaba esiqinileyo. Isigaba esinzima sinyanzelwa kumda wangaphandle wesitya, ngelixa isigaba esikhaphukhaphu sityhalelwa embindini. Izigaba ezahluliweyo zikhutshwa ngee-outlets ezahlukeneyo, okuvumela ukukhutshwa okusebenzayo kwezinto ezifunekayo.

Enye yezona ndlela ziphambili zokusetyenziswa kwe-2 phase decanter kukucubungula amanzi amdaka kwimizi-mveliso. Kwizityalo zonyango lwamanzi amdaka, i-2 phase decanter ingasetyenziselwa ukwahlula izinto eziqinileyo ezixhonyiweyo kwi-liquid phase, okuvumela ukususwa kwezinto ezingcolisayo ngaphambi kokuba amanzi acociweyo abuyiselwe kwindalo esingqongileyo. Ukongeza, i-2 phase decanter isetyenziswa rhoqo kwishishini lokutya neziselo ukucacisa iijusi, ukwahlula ioyile emanzini, kunye nokukhuculula amanzi amdaka.

Ukusebenza kwe-decanter yesigaba esi-2 kulula kakhulu. Umxube wesondlo ufakwa kwisitya esijikelezayo, apho amandla e-centrifugal abangela ukwahlukana kwezigaba. Isigaba esinzima, njengezinto eziqinileyo, siqokelelwa kwaye sikhutshwe nge-outlet enye, ngelixa isigaba esilula, njengolwelo, siqokelelwa kwaye sikhutshwe nge-outlet enye. Ukusebenza kakuhle kwenkqubo yokwahlula kuchatshazelwa zizinto ezifana nesantya sokujikeleza kwesitya, isantya sokuhamba kokutya, kunye neempawu zomxube wesondlo.

Inzuzo ephambili ye-2 phase decanter ikwindlela elula neguquguqukayo. Ifanelekile kakhulu kwimisebenzi eyahlukeneyo yokwahlulahlula ulwelo kwaye ingadityaniswa ngokulula kwiinkqubo zoshishino ezikhoyo. Nangona kunjalo, kubalulekile ukuqaphela ukuba i-2 phase decanter inqunyelwe ekuhlukaniseni izigaba ezibini ezahlukeneyo, kwaye ayifanelekanga ukusetyenziswa apho isigaba sesithathu, njenge-emulsion, kufuneka sijongwane nayo.

Isivalo seSigaba esi-3

I-decanter yesigaba esi-3, eyaziwa ngokuba yi-decanter yesigaba esi-3, yi-centrifuge ekhethekileyo eyenzelwe ukwahlula ngaxeshanye izigaba ezintathu ezahlukeneyo kumxube wezondlo. Ukongeza kwizigaba zolwelo neziqinileyo, i-decanter yesigaba esi-3 iyakwazi ukwahlula i-inmiscible liquid phase, njengeoyile, kumxube wezondlo. Olu buchule lukhethekileyo lwenza i-decanter yesigaba esi-3 ifaneleke kakuhle kwizicelo apho ukukhupha izinto ezixabisekileyo, njengeoyile, kufuneka kunye nokususwa kwezinto eziqinileyo kunye nokucaciswa kwesigaba solwelo.

Enye yeendlela eziphambili zokusetyenziswa kwe-3 phase decanter kukucubungula i-oyile ekrwada. Kwishishini leoyile negesi, i-3 phase decanter isetyenziselwa ukwahlula i-oyile ekrwada ibe ziinxalenye zayo ezintathu eziphambili: ioyile, amanzi, kunye nezinto eziqinileyo. Le nkqubo, eyaziwa ngokuba kukwahlulwa kwe-oyile-amanzi-izinto eziqinileyo, ibalulekile kwimveliso efanelekileyo ye-oyile ekrwada esemgangathweni ophezulu kunye nokususwa kwezinto ezingcolisayo ezinokubangela iingxaki zokucubungula ezisezantsi.

Uyilo lwe-decanter yesigaba esi-3 lufana nolwe-decanter yesigaba esi-2, enesitya esijikelezayo kunye nesiphelo esikhonkrithi. Nangona kunjalo, i-decanter yesigaba esi-3 ixhotyiswe ngeempawu ezongezelelweyo ukuze kube lula ukwahlulahlula kwangaxeshanye kwamanqanaba amathathu. Umxube wesondlo ungeniswa kwisitya esijikelezayo, apho amandla e-centrifugal abangela ukwahlukana kwamanqanaba amathathu. Isigaba ngasinye siqokelelwa kwaye sikhutshwe ngee-outlet ezahlukeneyo, okuvumela ulawulo oluchanekileyo malunga nokukhupha izinto ezifunekayo.

Ukusebenza kwe-decanter yesigaba esi-3 kufuna ukuqwalaselwa ngononophelo kwezinto ezifana neempawu zomxube wesondlo, isantya sokujikeleza kwesitya, kunye nejometri yangaphakathi ye-centrifuge. Ukulungiswa ngokufanelekileyo kwezi parameters kubalulekile ukuqinisekisa ukwahlula ngokufanelekileyo kwezigaba ezi-3 kunye nokunciphisa ukulahleka kwezinto ezixabisekileyo.

Inzuzo ephambili ye-3 phase decanter ikukwazi kwayo ukuphatha imixube yokutya eyinkimbinkimbi equlethe izigaba ezintathu ezahlukeneyo. Oku kuyenza ibe sisixhobo esixabisekileyo kumashishini afana neoyile negesi, ukucubungula ukutya, kunye nonyango lwamanzi amdaka, apho ukwahlulwa ngaxeshanye kwezinto ezininzi kubalulekile kumgangatho wemveliso kunye nokuthobela okusingqongileyo. Nangona kunjalo, kubalulekile ukuqaphela ukuba i-3 phase decanter sisixhobo esikhethekileyo kwaye isenokungafaneleki kwizicelo ezibandakanya izigaba ezimbini ezahlukeneyo kuphela.

Uthelekiso lweeDecanters zeSigaba esi-2 kunye neSigaba esi-3

Xa kuthelekiswa i-decanter yesigaba sesi-2 kunye ne-decanter yesigaba sesi-3, umahluko obalulekileyo uyabonakala. Umahluko ocacileyo ukho kwinani lezigaba ezinokukwazi ukwahlula i-decanter nganye. I-decanter yesigaba sesi-2 yenzelwe ukwahlula izigaba ezibini, ngesiqhelo ulwelo kunye ne-solid, ngelixa i-decanter yesigaba sesi-3 yenzelwe ukwahlula izigaba ezintathu ngaxeshanye, kuquka ulwelo olungenakudityaniswa kunye nezinto eziqinileyo ezibini.

Omnye umahluko obalulekileyo bubunzima bemixube yokutya enokucutshungulwa ngempumelelo. I-decanter yesigaba sesibini ifanelekile kwimixube yokutya elula equlethe izigaba ezimbini ezahlukeneyo, ngelixa i-decanter yesigaba sesithathu iyimfuneko kwimixube yokutya enzima equlethe izigaba ezintathu. Oku kwenza i-decanter yesigaba sesithathu ibe sisixhobo esikhethekileyo kumashishini apho ukwahlulwahlulwa kwezinto ezininzi kuyimfuneko ebalulekileyo yokucubungula.

Ngokwendlela ezisetyenziswa ngayo, i-decanter yesigaba sesi-2 isetyenziswa kakhulu kumashishini afana nokucoca amanzi amdaka, ukucubungula ukutya neziselo, kunye nokuvelisa iikhemikhali, apho ukwahlulwa kwezinto eziqinileyo kwizinto ezimanzi kuyinyathelo eliqhelekileyo lokucubungula. I-decanter yesigaba sesi-3, kwelinye icala, ifumana ukusetyenziswa kwayo okuphambili kumashishini afana neoyile negesi, apho ukwahlulwa kweoyile, amanzi, kunye nezinto eziqinileyo ngaxeshanye kubalulekile kwimveliso efanelekileyo yeemveliso ezisemgangathweni ophezulu.

Ngokwembono yokusebenza, zombini i-decanter yesigaba sesibini kunye ne-decanter yesigaba sesithathu zifuna ukuqwalaselwa ngononophelo kweeparameter ezifana nesantya sokujikeleza kwesitya, izinga lokuhamba kokutya, kunye neempawu zomxube wesondlo. Ukulungiswa ngokufanelekileyo kwezi parameters kubalulekile ukuqinisekisa ukwahlukana okusebenzayo kunye nokunciphisa ukulahleka kwezinto ezixabisekileyo.

Kubalulekile ukuqaphela ukuba ukhetho phakathi kwe-decanter yezigaba ezi-2 kunye ne-decanter yezigaba ezi-3 kufuneka lusekelwe kwiimfuno ezithile zokucubungula isicelo. Nangona i-decanter yezigaba ezi-2 sisixhobo esiguquguqukayo esifanelekileyo kwimisebenzi eyahlukeneyo yokwahlulahlula ulwelo, i-decanter yezigaba ezi-3 sisixhobo esikhethekileyo esenzelwe usetyenziso apho ukukhupha izinto ezininzi kubalulekile.

Isiphelo

Ukuqukumbela, umahluko ophambili phakathi kwe-decanter yesigaba esi-2 kunye ne-decanter yesigaba esi-3 usekwe kubuchule bazo bokwahlula izigaba kunye nokusetyenziswa kwazo kumashishini ahlukeneyo. I-decanter yesigaba esi-2 yenzelwe ukwahlula izigaba ezimbini ezahlukeneyo, njengolwelo kunye ne-solid, kwaye ifumana ukusetyenziswa kwayo okuphambili kumashishini afana nonyango lwamanzi amdaka kunye nokulungiswa kokutya. I-decanter yesigaba esi-3, kwelinye icala, yenzelwe ukwahlula izigaba ezintathu ngaxeshanye, kubandakanya ulwelo olungenakuxutywa kunye nezinto eziqinileyo ezimbini, kwaye isetyenziswa kakhulu kumashishini afana neoyile negesi. Zombini ezi ntlobo ze-decanter zifuna ukuqwalaselwa ngononophelo kwemilinganiselo yokusebenza ukuqinisekisa ukwahlula ngokufanelekileyo kunye nokukhupha izinto ezixabisekileyo.
