Hydrocyclones – INDLELA AQHAWE IZINDLELA ZOKUGCINA KULULA

I-Hydrocyclones ingenye yezingcezu ezisetshenziswa kakhulu zemishini yokufaka amaminerali. Idizayini yabo eyisisekelo ithembela ekucindezelweni kusuka ngaphandle ikhiqize ukunyakaza okujikelezayo engxube ye-liquid ngaphakathi kwayo, okubangela izinhlayiya ezisindayo ukuhlanganisa izindonga zawo ngaphambi kokukhipha endaweni yalo ephansi.

Bahlukanisa izinhlayiya

IHydrocyclones iyidivaysi e-static esebenzisa ukusheshisa kwe-centrifugal ukuhlukanisa izinhlayiya zezinto ezahlukahlukene ezivela kumanzi. Izinhlayiya eziminyene – Noma ngabe kuqinile noma uketshezi – dlulela emaphethelweni angaphandle we-vortex ngenkathi izinhlayiya ezilula zifudukela ezinkanjini zalo eziphakathi nendawo, nge-coarser kanye nezinhlayiya ezinkulu ezihamba nge-underflow yayo, Ngenkathi inhlawulo ihamba phambili iqhubekela phambili ngaphambi kokuphuma nge-apex yayo nge-centrifugal Force futhi ichichime ngokuchichima kwayo.

Ukusebenza Kwehlukaniso kuncike ezintweni eziningana, kufaka phakathi usayizi we-cyclone, ububanzi nokwakheka kanye namandla kagesi kanye nezakhiwo eziyizinhlayiyakazi maqondana nezimpawu eziphakathi nendawo. Izinto ezi-abrasive noma zokudla okuminyene ngeke zihlukaniswe ngempumelelo ne-hydrocyclones.

Izifundo ezahlukahlukene zihlolile imiphumela yobukhulu bezinhlayiyana kanye nokwakheka kokuhlukaniswa. Imiphumela ikhombisile ukuthi amabutho okuhunga alingana nezinhlayiya zendawo ephezulu etholwe eceleni kokugeleza koketshezi ku-hydrocyclone; Kashiya et al.. Uphenya le pharamitha kuzo zombili ukuhlukaniswa okukodwa nokuxubile nge-CFD-Dem Coupling Technology kanye nezindlela zokuhlola zokuhlola.

Njengesilinganiso sokusebenza kahle kokuhlukanisa, ukukala ukugcotshwa kwe “udumo” Ku-Overflow kuyindlela ekahle yokuhlola ukusebenza kwe-hydrocyclone. Lokhu kungenziwa ngephesenti le-volumetric macheji noma, ngokunemba ngokwengeziwe, Kusetshenziswa izilinganiso zesisindo.

Bahlukanisa izinhlayiya ezinobunzima

IHydrocyClones isebenzisa i-tangelial inlet velocity ukusondeza ukumiswa ngaphakathi, ukudala ukugeleza kwe-swirl kwangaphandle nokuhlukanisa izingxenye ezisindayo kusuka ku-liquid. Izakhi ezisindayo ezindodeni ezindongeni zesiphepho ngenkathi izinhlayiya ezikhanyayo ezilula zidlula ngokuphuma kwazo okuphezulu.

IHydrocyclones iphakathi kwemishini esetshenziswa kakhulu yokuhlukanisa izinhlayiya ezinhle nezama-coarse e-Pulp nephepha, Siyabonga kalula ukuklama kwabo, Ukusebenza kwezindleko, Ukusebenziseka kalula kanye nempilo yenkonzo ende ngaphandle kokudinga okuningi ngokwemigomo yesondlo noma yokufaka kusuka kuma-opharetha. Kodwa-ke ngisho nazo zonke izinzuzo zazo kungenzeka zisekele ukwehla kokusebenza ngokuhamba kwesikhathi.

Lapho uxazulula inkinga ngezinkinga nge-hydrocyclones, kungasiza ukuqonda ukusebenza kwawo kanye nezici ezithinta ukusebenza kwazo. Ukucatshangelwa okubalulekile ekusebenzeni kwabo kokuhlukana kungukucindezela okusetshenzisiwe ekungeneni kwabo – okunethonya elisheshayo kuzinhlayiya zezinhlayiya ezinqunyelwe ngokuya ngengcindezi esetshenzisiwe, Usayizi we-Cone ububanzi nohlobo lwezinto ezibonakalayo.

Ama-hydrocyclones eza ehlome ngomunye wemiklamo emithathu ye-inlet: -Tantial, okubandakanya noma i-arc. Imiphumela yokuhlola eyenziwe kusetshenziswa yonke imidwebo emithathu yokungena ngaphakathi. 7 kanye netafula 2, lapho i-arc inlet hydrocyclones ihlala ingenaminyene yabo bobabili abalingani babo ngezimo ezahlukahlukene zokuhlukaniswa kosayizi (-E okwenhla).

Bahlukanisa izinhlayiya ezinhle

Ama-Hydrocyclones angasetshenziswa ukuhlukanisa izinhlayiya ezinhle ngokusebenzisa ingcindezi ka-fluid ukukhiqiza iphethini yokugeleza ehlukanisa izinhlayiya ezisuselwa ekubunjweni nasekwakhekeni. Ukulungisa amazinga wengcindezi emugqeni wokuphakelayo kuguqula iphuzu lokuhlukanisa (ebizwa nangokuthi Cut Point); Ingcindezi ephansi idala ukusikeka kwama-coarser ngenkathi ingcindezi ephezulu ikhiqiza ukuhlukaniswa okuhle.

Hydrocyclones utilize their cone-shaped inner section to create a zone of low pressure, okusheshisa izinhlayiyana zokugcina izinhlayiyana. Izinhlayiya ezilungisa ngokushesha zingena odongeni lwesiphepho futhi ziphume ngokuvula kwayo kwe-apex njengokungena ngaphansi, Ngenkathi kulungiswa izinhlayiya ezisindayo kakhulu kunangaphambili zazo ezizungezile zidonswa phansi ngama-centrifugal Force futhi aqhamuke nge-vortex-Finder yawo njengokuchichima.

E- 6.5 mm kusuka odongeni lwesiphepho, izigaba eziyizinhlayiyana ezithile 6.5 Ibanga le-MM kusuka odongeni lwayo lulinganiswa njengesamba sokucindezela kwe-graestuent kanye nokudonsa, Ngokushesha ukudonsa kuchazwa njengokunyakaza okuhlobene phakathi kwezigaba. Yazo zonke izinambu ezisetshenziselwa izinhloso zokuhlukaniswa, Insimu ye-C's Strong Hudula Screening ichaza ubukhali bawo abaphezulu bokuhlukanisa ama-SCS aphezulu.

Bahlukanisa amanzi

IHydrocyClones isebenzisa ingcindezi kamanzi ukuze ikhiqize ama-centrifugal Force namaphethini okugeleza angahlukanisa izinhlayiya noma amaconsi kusuka ku-liquid medium. Ukuze lokhu kuhlukaniswa kwenzeke, Ubuningi babo kumele buhluke kakhulu kusuka kulokho okwenziwe ngoketshezi.

Idizayini ejwayelekile ifaka ukujova okuphakelayo ngejubane elikhulu ngesivinini esikhulu esigabeni esiphezulu se-cylindrical esijoyina umzimba onama-conical, Ukwakha ukunyakaza okuqinile koketshezi okuphoqa izinto ze-coarser ngokusebenzisa izitolo ezingezansi-axial ezaziwa ngokuthi izinhlangothi, futhi amahle ngokusebenzisa amashubhu aphezulu we-axial ezaziwa njengezinhlangothi ezichichimayo.

Ukulawulwa kobukhulu obukiwe kungenziwa ngokuguqula ingcindezi yokuphakelayo esiphelweni. Izilingo zokushayela zivame ukusebenzisa ama-valve amabili ukuze kuguqulwe ukuguquguquka kwezindawo ezitolo kuze kube yilapho inani le-D50 lilifunayo; Lapho lokhu sekunqunywe, I-orifice eyodwa ingangena esikhundleni sama-valves ekusebenzeni okujwayelekile.

Le mishini isetshenziswa kabanzi ekusebenzeni kwamaminerali ukuhlukanisa izinhlayiya zokuphinda ugaye imibuthano, hlukanisa phakathi kwamaminerali ezomnotho kanye ne-gangue, Amafutha ahlukile avela emanzini emikhakhelweni yokucwenga kanye nokususa ama-oyela aphesheya kwezilwandle bese ususa isihlabathi / isilika kusuka ekunikezelweni kwamanzi noma okuphamba amanzi, Phakathi kokunye okuningi okusetshenziswayo. Ngaphezu kwalokho, Le mishini nayo ingahle isetshenziswe njengokucebisa okukhuphukayo ukwehlisa umthwalo emishini yokuhlukanisa ebiza kakhulu ngenkathi uthuthuka okusebenzayo kwezomnotho.
