Njengoba ephumelelayo filtration amaphakathi, isisefo sephepha iye kabanzi emikhakheni ehlukahlukene. Ngokusho izinhlobo zemicu ezakha iphepha lemifanekiso, ukusebenza kanye nokusetshenziswa iphepha isihlungi nazo ezahlukene. Ingasetshenziselwa ngoba isihlungi ezivamile iphepha izikhathi jikelele, ingilazi fibre isisefo sephepha ngoba izinga lokushisa eliphakeme, futhi polypropylene isisefo sephepha ngoba ultra-kuhlanzekile.
Isakhiwo isisefo sephepha isakhiwo uxhaxha sakhiwa zemicu iziteshi, okuyinto kanye amabutho ngokomzimba elihlobene ne-uketshezi bakha umsebenzi ukusefa isisefo sephepha. Mshini filtration simiswe ngalendlela lelandzelako:
1. bamba okuqondile noma ukucabhela
Kule nqubo, abanye abantu ngephutha bakholelwa ukuthi iyisici kuphela ukwakha filtration, nokuthi izinhlayiya ukungcola avimbelwe e ebusweni inflow noma uxhaxha kuphela ngoba kukhona kunenani beso. Eqinisweni, kukhona:
2. Adsorption
Lapho uketshezi elicwengekileyo sidlula uxhaxha, abanye izinhlayiya adsorbed kuya isisefo sephepha ngaphansi isenzo Luhambo electrostatic, nakuba ububanzi ezinye izinhlayiya lincane kakhulu kunenani beso. Ngakho-ke, ezinye izinto esihlungini ngokukhethekile nge zikagesi ngesikhathi senqubo yokukhiqiza.
3. Hit nokuwa
Kule nqubo, ngenxa ubudlelwano phakathi ukugeleza rate, izinhlayiya babambeke ngqo ebusweni isisefo sephepha fibre kunokuthembela Pore iphepha lemifanekiso, futhi ibutho adsorptive namanzi ukugeleza amandla ayagcinwa kuso, ngaleyo ndlela ekuvimbeni ezinye izinhlayiya ezincane.
4. Filtration futhi agglomeration
Nge ekuqongeleleni okuqhubekayo ngokudlulisa izinhlayiya phezu isisefo sephepha, it yakha isihlungi ungqimba ngokwayo, okuyinto izicupho izinhlayiya ezincane in pores phakathi izinhlayiya ezinkulu. Saneliswe ngokuthela kwezindebe izinhlayiya, ukumelana kwandisa ngokuqhubekayo, kwaze kwaba yilapho ekugcineni sivinjelwe ngokuphelele noma lifike ingcindezi umehluko.
Ukukhiqizwa isisefo sephepha silula. Kumane nje kuwukuthi ezihlukahlukene imicu eminingana ofakwe binders amanzi-based ngibasakaza ngokuphelele, bese akha uvalwe eziboshiwe uxhumano iphepha roll esikrinini kasilika. Ngokusebenzisa omiswe, ekushoniseni kanye omiswe, lo eyamukelekayo nomswakama ezingeni abayifunayo. Kodwa eqinisweni, ukukhiqizwa kwanoma kahle isisefo sephepha, ngokugcina ukusebenza efanayo phakathi batch kanye batch, roll and Roll, ngisho ephakathi kwengu neminyaka, kuzodinga yayo isisindo, porosity, permeability, amandla nezinye izinguquko ibanga elincane.
Indaba isihlungi e lemifanekiso kumelwe ukuvimbela uhlelo isihlungi ekubeni kabana izinhlayiya eziyingozi, futhi ngesikhathi esifanayo avumele uketshezi ngokwanele ukuba adabule, ukuze ugweme cavitation e futha, umsebenzi isilinda futhi amandla omlilo ekamelweni. Okwazekayo, isihlungi ephelele kufanele ususe 100% we izinhlayiya enobuthi futhi ahlinzeke uhambisane emoyeni permeability. Kodwa eqinisweni, lokhu akunakwenzeka.
Umklamo isisefo sephepha kumelwe senze wonke umzamo ukuze kube nokulingana izinkomba ezahlukene ukuze kuvikelwe ngempumelelo uhlelo kuhlungwe. Amafutha Okokuhlunga izidingo ephakeme isisefo sephepha kuka air izihlungi, ikakhulu ngenxa lokuhlushwa uwoyela eshintsha esihambelana ngaphansi lokushisa izinguquko ezinqala, okuyinto sizothinta filtration ukugeleza uwoyela.
