Adsorbent-ka uu nuugo shaandhada hore loo nuugay iyo biyaha la sifeeyay ee la qasi jiray ama dareeraha shaandhada ayaa lagu qasaa hakin ku jira baaldi quudinta, ka dib marka la fiirsado dareeraha la nuugo ayaa gaadha shuruudaha, dareeraha shaandhada waa la kala saaraa. Geli, horay u sii wad Dhexdhexaadiyaha tooska ah ee daahan (doorku guud ahaan waa lagu dabaqi karaa shaashadda filtarka ballaarinta. Dhumucda lakabka millimitirka guud ahaan waa 3-80. Wax soo saarka dhabta ah ee shaashadda shaandhada, keega ayaa sidoo kale si joogto ah loo gooyn karaa (sida mashiinka shaandhada vacuum filter filter), taas oo noqon karta mid cusub Sariirta shaandhada waa mid deggan oo deggan.
(2)Percolation:
Sifeynta roobabka waxaa lagu fuliyaa laba tallaabo: hore-u-dhigista iyo ku-darka: dhumucda hore ee daboolka guud ahaan waa 2-3 mm. Shaqada ugu muhiimsan waa in la ilaaliyo walxaha shaandhada si ay u nuugaan wasakhowga, isla markaana u beddelaan daahan polymer marka lagu daro shaandhada. Dahaarka hore ee dahaarka guud ahaan waa 2-3 mm. Dhumucda iyo qaab-dhismeedka ayaa muhiim u ah geeddi-socodka oo dhan. Marka loo eego dabeecadda shayga shaandhada (viscosity, particle and content, filterability compressible of particles, iwm.), isticmaaluhu wuxuu isticmaali karaa hababka soo socda:
(1) Dahaarka ka hor
Dahaarka ka hor waxaa la sameeyaa by saamaynta isku xidhka eeshaandhaynta gargaarka filterdhanka dhexe. Haa: Ka ilaali dhexdhexaadiyaha shaandhada (dareeraha la shaandhayn doono) qaybaha shaandhada; sifaynta waxaa la heli karaa bilowga sifaynta; dhexdhexaadiyaha shaandhada way fududahay in la xidho. Marka hore loo daboolo, gargaarka shaandhada gaarka ah iyo dareeraha saafiga ah (ama jeermiska jeermiska) ayaa loo qaybiyaa 5-10% (saamiga mass) hakinta haanta hore ee dahaarka, iyo dahaarka hore ee wanaagsan oo xasilloon ayaa lagu sameeyay dhexdhexaadiyaha shaandhada iyada oo loo marayo bamka wareegga. daahan. Dhumucdiisuna waxay tahay 2-4mm dhumucdiisuna waxay tahay 2-4MM Shaandheeyaha hawada laba jibaaran wuxuu u baahan yahay dahaarka hore ee 8-15CM. Shuruudaha sifaynta cad, oo leh dareere muuqaalkiisu hooseeyo (qiyaastii 1CP), heerka socodka dahaarka hore ee caadiga ah waa ilaa 40L/m², iyo dareeraha maw-jiifka hoose ee socodka hore ee dahaarka ayaa loo dhimay si waafaqsan.
(2) Ka dib marka lagu daro gargaarka shaandhada si loo shaandheeyo iyo hore u-daboosho, ka dib marka budada shaandhada ay gasho shaandhada, waxaa lagama maarmaan ah in lagu daro gargaarka shaandhada 0.1-2.0% miisaanka dareeraha. Habka sifaynta, gargaarka shaandhada iyo walxaha wasakhda ah ee ku jira dareeraha shaandhada ayaa lagu daraa miiraha si u dhigma. Qadarka dheeriga ah wuxuu ilaaliyaa cadadka iyo isku-buufinta qaybaha la sameeyay. Nijaasta leh heerka cadaadisku sarreeyo, qaddarka kaalmada shaandhada lagu daray waxay u dhigantaa kororka. Ku-darka filtarka waa in la sameeyaa marka cadaadiska shaandhada uu gaaro cadaadiska. Shaashadda shaandhada asal ahaan ka buuxsamay shaashadda shaandhada ayaa u oggolaanaysa dhammaystirka booska shaandhada nuugista. Halkaa marka ay marayso wareegga sifaynta, shaashadda shaandhada waxay gashaa marxaladda xayeysiinta.
(3) Si toos ah ugu dar shaandhaynta:
Caawinta shaandhada iyo maaddooyinka adag ee ku jira shaandhada shaandhada ayaa la wada dul dhigaa lakabka hore ee asalka ah ama lakabka shaandhaynta si loo sameeyo lakab cusub, si shaandhuhu u ilaaliyo xaalad deggan. Xawaaraha sifaynta. Waqtigan xaadirka ah, cabbirka qayb ka mid ah gargaarka shaandhada Wu Jia waxaa kaliya oo lagu go'aamiyaa sifooyinka qaabka shaandhada shaandhada, oo aan saameyn ku yeelan samaynta shaandhada.
