I-Hydrocyclones Yokwehlukanisa Okuqinile Koketshezi Oluqinile

Ama-Hydrocyclone aklanyelwe ukuthuthukisa ukusebenza kokuhlukanisa ngenkathi ngesikhathi esifanayo ehlisa ukusetshenziswa kwamandla ngokushintsha ukugeleza koketshezi ngaphakathi kwedivayisi..

Ukwehlukaniswa okuyisisekelo kwenzeka engxenyeni yesiyilinda yesishingishane ngaphambi kokuba izinhlayiya zingene esigabeni se-conical ngezinqubo ezengeziwe zokuhlukanisa ezincike ekumineni kokuphakelayo..

I-Cyclone Geometry

I-cyclone ucezu lwesisetshenziswa esiyindilinga esisebenzisa amandla aphakathi nendawo ukuhlukanisa izinhlayiya ezinkulu noma amaconsi phakathi nendawo.. Lapho amandla ayo e-centrifugal edlula amandla okudonsa oketshezi, izinhlayiya ezinkulu noma eziminyene ziphuma endaweni ephezulu phezulu, kuyilapho izinhlayiya ezicolekile noma ezinqatshiwe ziphuma ngezindawo zokulahla eziphansi.

Imiklamo ye-Tangential inlet ikhuthaza ukwakheka okuqinile kwe-vortex, ukwandisa ukusebenza kahle kokuhlukana. Ngaphezu kwalokho, umklamo uvimbela ukugeleza kwesifunda esifushane okwenzeka lapho igesi yesivinini esiphezulu ingena kusihlukanisi.

Ukuze uthole ukusebenza kahle kokuhlukanisa, umzimba/umgqomo wesiphepho kufanele ulinganiswe ngokufanele ukuze kuqinisekiswe ukusebenza kahle kokuhlukana. Ukunquma lokhu, bheka isifutho esiphephezelayo esincane njengoba okubalulekile kuphuma phezulu kwesishingishane; lokhu kukhombisa ukuthi ilinganiswe ngokufanelekile. Uma esikhundleni salokho okubalulekile kuphuma ngaphansi kwesihlukanisi sakho esikhundleni salokho, noma ukhuphule umfutho wokuphakelayo/ukugeleza noma unciphise usayizi wokusika (i.e. ihuqe).

Ama-Slits aphuphumayo

Idizayini ye-slits echichimayo inomthelela omkhulu ekusebenzeni kahle kokuhlukaniswa kwe-hydrocyclone kanye nesilinganiso sokuhlukaniswa. Ngenjwayelo, ukusebenza kukhuphuka ngokwanda kobubanzi bokuqhekeka okuchichimayo kanye nokuncipha kobubanzi bokuqhekeka okungaphansi kokugeleza.

Lapho idliwe isishingishane, udaka luzungeza ngaphakathi kwezindonga zalo eziyisilinda okudala amandla aphakathi nendawo ukuze ahlele izinto ngokuminyana. Izinhlayiya ezinzima zishayisana odongeni futhi zidonselwa phansi ngepayipi eliphumayo elibizwa ngokuthi i-vortex finder ngaphambi kokuphuma ngepayipi eliphumayo elingaphansi.; ezisindayo zihlala zivaleleke kuwo futhi ngaleyo ndlela zinqwabelane lapho zize zichichime ngesitholi se-vortex noma ipayipi lokuphuma kwe-vortex finder.

Ukuze uthole ukusebenza kahle kwe-hydrocyclone, isilinganiso esifanele phakathi kwe-axial velocity kanye ne-tangential velocity kufanele kufinyelelwe ukuze kuncishiswe ukushuba kwezinxushunxushu nokulahlekelwa amandla ngaphakathi kwezindonga zayo futhi kuvumela izinhlayiya zokukhanya ukuthi zifinyelele amandla anele e-centrifugal ukuze zifinyelele indawo yazo echichimayo..

I-Orifice Angles

Uma idliswa nge-tangentially kusilinda sesiphepho, isenzo sayo sokuphotha siguqula isivinini soketshezi sibe amandla amaphakathi adonsela izinhlayiya ezisindayo ngasodongeni kuyilapho izinhlayiya ezilula kancane zihlangana futhi zisongelwa phezulu ukuze ziphume endaweni yazo yokuchichima ephezulu.; izinhlayiya ezisindayo kakhulu bese ziwela emuva endaweni yayo yokulahla engaphansi ngoketshezi oluthile ngeshubhu elinwetshiwe (ebizwa ngokuthi i-vortex finder).

Ukuhlukaniswa kwe-Hydrocyclone kungenziwa ngempumelelo ngokusebenzisa amaphethini okugeleza okungagundi okunciphisa amandla okugunda; amadizayini angenawo ama-shear angase anikeze ezinye izinzuzo ngaphezu kokuhlunga kwemidiya okungokwesiko njengokwandisa impilo yokupholisa. Lapho uklama uhlelo, nokho, ukugunda kufanele kubhekwe.

I-Axial Velocity Distribution

Lapho amandla e-centrifugal edlula amandla okungqubuzana atholwa uketshezi, izinhlayiya ezinzima zihlukaniswa noketshezi futhi ziphuma nge-axial bottom outlet (ukugeleza ngaphansi) kuyilapho uketshezi olulula lungena endaweni yokuphuma ephezulu ye-hydrocyclone (phuphuma).

I-cyclone inezindawo ezimbili zokuphuma ku-axial axis yayo; eyodwa phansi eyaziwa ngokuthi “yenqaba side,” kanye nenye indawo enkulu yokuphuma phezulu eyaziwa ngokuthi “ukuchichima uhlangothi.” Umjovo we-Tangential ekamelweni layo eliyi-cylindrical udala iphethini yokugeleza ejikelezayo; ukuphuma ohlangothini oluchichimayo kudlula ipayipi le-axial eliphumela phezulu kwesishingishane.

Nokho, izici ezingokwemvelo zokugeleza koketshezi ziholela ekuhlukaneni okungaphelele nokulahlekelwa amandla kungakhathaliseki ukuthi ijometri. Kuhloswe ngedizayini efaneleke, kuye kwahlongozwa futhi kwahlolwa imiklamo ehlukahlukene yokuthuthukisa ukugeleza kwamanzi – njengokufaka umzimba ophakathi nendawo9, i-cone yangaphakathi11, amapayipi aphuphuma kabili12-13, slit cone14 kanye ne-cap15 echichimayo ngokwesibonelo; konke kubonise ukunciphisa ububanzi be-air core ngenkathi kukhulisa ukusebenza kwezigaba zezinhlayiyana.
