Isingeniso sokuhlunga kwangaphambili

Okubizwa ngokuthi i-filtration pre-coating iwukwengeza inani elithile losizo lokuhlunga ohlelweni lokuhlunga, futhi ngemva kwesikhathi esifushane, ukuhlunga okuzinzile kwangaphambi kokugcoba kwenziwa entweni yokuhlunga, okuguqula ukuhlungwa kwe-media elula kube ukuhlunga okujulile, okuholela ekuhlanzeni okuqinile nomphumela wokuhlunga. Izinsiza zokuhlunga ezivame ukusetshenziswa yi-perlite, i-cellulose, umhlaba we-diatomaceous, i-carbon black ne-asbestos. Usizo lokuhlunga lwe-Diatomite lusetshenziswe kabanzi ngenxa yezinzuzo zalo eziphelele ekusebenzeni, intengo, umthombo nezinye izici.

Isimiso sokuhlunga kwangaphambili

Iphampu yokuhlunga isetshenziselwa ukudlulisa ukumiswa okuqukethe usizo lwesihlungi ku-tank yesihlungi, futhi ngemva kwesikhathi sokujikeleza, usizo lokuhlunga luboshwe phezu kwendawo yokuhlunga ukuze kwakheke isendlalelo sokumboza ngaphambili esinezimbotshana eziyinkimbinkimbi nezicolekileyo. Ngenxa yokuba khona kwe-pre-coating, ukunemba okuphezulu kokuhlunga kutholakala esigabeni sokuqala sesinyathelo esilandelayo sokuhlunga, futhi kungavimbela izinhlayiya zokungcola ekuvaleni ama-pores wesici sokuhlunga. Phakathi nenqubo yokuhlunga, izinhlayiya eziqinile ekumisweni zixubene nezinhlayiya ze-diatomaceous zomhlaba ezingezelelwa ngokuqhubekayo ngendlela yobuningi bese zinqwabelana kusici sokuhlunga ukuze zenze ikhekhe lokuhlunga elixekethile, ukuze izinga lokuhlunga lizinze ngokuyisisekelo.

Izici zosizo lwesihlungi se-diatomite

Imikhiqizo yosizo lokuhlunga i-Diatomite iza ngemibala ehlukahlukene. Ingxenye yayo eyisisekelo wudonga lwegobolondo olunezimbotshana ze-siliceous. Izinkomba zokusebenza eziyinhloko ziwusayizi wezinhlayiyana, ukuminyana kwenqwaba, indawo ethile engaphezulu, nokuqukethwe kwengxenye. Phakathi kwazo, ukusatshalaliswa kosayizi wezinhlayiyana kungenye yezinkomba zokusebenza ezibaluleke kakhulu. Inquma ngokuqondile ubukhulu be-pores yokuhlunga kanye nokusatshalaliswa kwama-micropores. Izinhlayiya ezinohlamvu oluqinile zinokungena kwamanzi okungcono, kodwa ukunemba kokuhlunga kuphansi, ngakho-ke izinga lokugeleza elidingekayo kanye nokunemba kokuhlunga kufanele kuhlangatshezwe. , Khetha ubukhulu obufanele bomhlaba we-diatomaceous. Imikhiqizo ekhiqizwa ekhaya ihlukaniswe yaba izinhlobo ezimbili zokujiya, ezingasetshenziswa yodwa noma zihlanganiswe nobukhulu obuhlukene nosayizi wezinhlayiyana ukuze kutholwe ukunemba kokuhlunga okuphezulu kakhulu. Ukuminyana kwenqwaba ye-diatomite nakho kunethonya elikhulu kumphumela wokuhlunga. Uma kuncane ukuminyana kwenqwaba, ivolumu yembotshana yezinhlayiya zosizo lwesihlungi iba nkulu, nokungeneka kwayo kanye nokukhanga kwayo kufanele kulawulwe ngesikhathi sokusebenza kwangaphambi kokumbozwa. Ukuhlushwa kwe-diatomite ephakathi kanye nesilinganiso sokugeleza okujikelezayo kwesisombululo sangaphambi kokumboza kwenza izinhlayiya ze-diatomite zivale ukwakheka kwe-pre-coating efanayo. Ukuhlushwa kwe-diatomite ngokuvamile ku-0.3 kuya ku-0.6%, futhi izinga lokugeleza elijikelezayo lingasethwa libe izikhathi ezi-1 kuya kwezi-2 kunezinga lokugeleza elivamile. Ingcindezi yangaphambi kokumboza ngokuvamile icishe ibe ngu-0.1MPa.
