Horudhac sifaynta hore ee dahaarka

Waxa loogu yeero shaandhaynta hore ee dahaarka ayaa ah in lagu daro qadar cayiman oo ah gargaarka shaandhaynta ee habka shaandhaynta, iyo wakhti yar ka dib, dahaarka hore ee shaandhaynta ayaa lagu sameeyaa qaybta shaandhada, taas oo u rogaysa shaandhaynta dusha warbaahinta fudud ee sifeynta qoto dheer, taasoo keentay nadiifinta xooggan iyo saamaynta shaandhaynta. Caawiyeyaasha filtarrada sida caadiga ah loo isticmaalo waa perlite, cellulose, dhulka diatomaceous, kaarboon madow iyo asbestos. Caawinta filter-ka Diatomite ayaa si weyn loo isticmaalay iyadoo ay ugu wacan tahay faa'iidooyinkeeda dhameystiran ee waxqabadka, qiimaha, isha iyo dhinacyo kale.

Mabda'a sifaynta hore ee dahaarka

Bamka shaandhada ayaa loo isticmaalaa in lagu dhaafo hakinta ay ku jirto gargaarka shaandhada taangiga shaandhada, iyo ka dib muddo wareegga wareegga ah, gargaarka shaandhada ayaa lagu xidhaa dusha sare ee dhexdhexaadiyaha si loo sameeyo lakabka hore ee shaandhaynta leh daloolo adag oo fiican. Sababtoo ah joogitaanka dahaarka hore, saxnaanta shaandhaynta sare ayaa lagu helaa marxaladda hore ee tallaabada xigta ee sifeynta, waxayna sidoo kale ka hortagi kartaa walxaha wasakhda ah inay xiraan daloolada xubinta shaandhada. Inta lagu jiro habka sifeynta, qaybaha adag ee ganaaxa waxaa lagu qasi karaa qaybo dhulka diatomaceous kuwaas oo si joogto ah loogu daray hab tiro ka dibna lagu ururiyey on element filter si ay u sameeyaan kee filter dabacsan, si heerka shaandhaynta waa asal ahaan xasilloon.

Astaamaha gargaarka shaandhada diatomite

Alaabooyinka gargaarka filter-ka Diatomite waxay ku yimaadaan midabyo kala duwan. Qaybteeda aasaasiga ah waa gidaarka qolofka siliceous daloolsan. Tilmaamayaasha waxqabadka ugu muhiimsan waa cabbirka walxaha, cufnaanta bulk, bedka dusha gaarka ah, iyo waxyaabaha ka kooban. Waxaa ka mid ah, qaybinta cabbirka walxaha waa mid ka mid ah tilmaamayaasha waxqabadka ugu muhiimsan. Waxay si toos ah u go'aamisaa xajmiga daloolada shaandhada iyo qaybinta micropores. Qaybaha qashin-qubka ah waxay leeyihiin qulqul-biyood ka wanaagsan, laakiin saxnaanta sifaynta ayaa ka hooseeya, markaa heerka socodka loo baahan yahay iyo saxnaanta sifaynta waa in la buuxiyaa. , Dooro dhumucda ku habboon ee dhulka diatomaceous. Alaabooyinka gudaha lagu soo saaro waxay u qaybsan yihiin laba nooc oo dhumucdiisuna tahay, kuwaas oo la isticmaali karo kaligood ama lagu daro dhumucyo kala duwan iyo cabbirka walxaha si loo helo saxnaanta sifaynta aadka u sareysa. Cufnaanta ugu badan ee diatomit waxay sidoo kale saameyn weyn ku leedahay saameynta shaandhaynta. Inta yar ee cufnaanta bulk, ayaa sii weynaada mugga daloolka ee qaybaha gargaarka shaandhada, iyo xajinta iyo xajinta waa in la xakameeyaa inta lagu jiro hawlgalka hore ee dahaarka. Isku-dubarid dhexdhexaad ah oo dhexdhexaad ah iyo wareegga wareegga wareegga ee xalinta hore ee dahaarka ayaa awood u siinaya qaybaha diatomite si ay u xakameeyaan samaynta dharka hore ee dharka. Isku-duubnaanta diatomite guud ahaan waa 0.3 ilaa 0.6%, heerka socodka wareega waxa lagu dejin karaa 1 ilaa 2 jeer heerka socodka caadiga ah. Cadaadiska hore ee dahaarka guud ahaan waa ilaa 0.1MPa.
