Intshayelelo yokucoca kwangaphambili

I-filtration ebizwa ngokuba yi-filtration pre-coating kukongeza isixa esithile soncedo lokucoca kwinkqubo yokuhluza, kwaye emva kwexesha elifutshane, i-filtration pre-coating ezinzileyo yenziwa kwi-filtration element, eguqula ukuhluzwa kwe-media elula kwi-filtration enzulu, okubangelwa ukuhlanjululwa okunamandla kunye nesiphumo sokucoca. Izixhobo zokucoca ezisetyenziswa ngokuqhelekileyo ziyi-perlite, i-cellulose, umhlaba we-diatomaceous, i-carbon black kunye ne-asbestos. I-Diatomite filter aid isetyenziswe ngokubanzi ngenxa yeenzuzo zayo ezibanzi ekusebenzeni, ixabiso, umthombo kunye neminye imiba.

Umgaqo wokucoca kwangaphambili

Ipompo yokucoca isetyenziselwa ukugqithisa ukumiswa okuqulethe uncedo lokucoca kwi-tank yokucoca, kwaye emva kwexesha lokujikeleza, uncedo lokucoca lufakwe kwibhulorho phezu kwendawo yokucoca ukwenza i-filter pre-coating layer with complex and fine pores. Ngenxa yobukho be-pre-coating, ukuchaneka okuphezulu kokucoca kufunyenwe kwinqanaba lokuqala lesinyathelo esilandelayo sokuhluza, kwaye kunokuthintela amaqhekeza okungcola ukuba avale iipores zesici sokucoca. Ngexesha lenkqubo yokuhluza, amasuntswana aqinileyo ekumisweni axutywe kunye namasuntswana omhlaba ediatomaceous adityaniswe ngokuqhubekayo ngendlela yobuninzi aze aqokelelwe kwinto yokucoca ukwenza ikeyiki yokucoca ekhululekileyo, ukuze izinga lokuhluza lizinze ngokusisiseko.

Iimpawu zoncedo lokucoca lwediatomite

Iimveliso zoncedo lokucoca iDiatomite ziza ngemibala eyahlukeneyo. Inxalenye yayo esisiseko ludonga lweqokobhe le-siliceous ene-porous. Iimpawu eziphambili zentsebenzo zibukhulu bamasuntswana, ubuninzi bobuninzi, indawo ethile yendawo, kunye nomxholo wecandelo. Phakathi kwabo, ukusabalalisa ubungakanani be-particle enye yezona zibonakaliso ezibalulekileyo zokusebenza. Inquma ngokuthe ngqo ubungakanani bee-pores zokucoca kunye nokusabalalisa i-micropores. Iingqungquthela ezinobuncwane ezinobuncwane obungcono bamanzi, kodwa ukuchaneka kokucoca kuphantsi, ngoko ke izinga lokuhamba elifunekayo kunye nokuchaneka kokucoca kufuneka kuhlangane. , Khetha ubukhulu obufanelekileyo bomhlaba we-diatomaceous. Iimveliso eziveliswe ekhaya zohlulwe zibe ziindidi ezimbini zobukhulu, ezinokuthi zisetyenziswe zodwa okanye zidityaniswe nobukhulu obahlukeneyo kunye nobukhulu bamasuntswana ukuze kufumaneke ukuchaneka kokucoca okuphezulu kakhulu. Ubuninzi bobuninzi be-diatomite nabo bunempembelelo enkulu kwimpembelelo yokucoca. Okukhona kuncinci ukuxinana kwesambuku, kokukhona umthamo wepore wamasuntswana oncedo lokucoca, kunye nokungena kwawo kunye nokufakwa kwe-adsorption kufuneka kulawulwe ngexesha lomsebenzi wangaphambili wokugquma. Ukuxinwa kwe-diatomite ephakathi kunye nesantya sokujikeleza kwesisombululo se-pre-coating senza ukuba iinqununu ze-diatomite zidibanise ukubunjwa kwe-uniform pre-coating. I-concentration ye-diatomite ngokuqhelekileyo i-0.3 ukuya kwi-0.6%, kwaye isantya sokuhamba okujikelezayo sinokumiselwa kwi-1 ukuya ku-2 amaxesha okuhamba okuqhelekileyo. Uxinzelelo lwe-pre-coating ngokubanzi malunga ne-0.1MPa.
