iindaba

(1)Ukuhluza umaleko wesihluzi:

I-adsorbent efunnwe yi-filtrate efakwe ngaphambili kunye namanzi ahlanjululweyo ahlanjululweyo okanye i-slurry yokucoca ixutywe kwi-suspension kwi-bucket yokutya, kwaye emva kokuba ukuxinwa kolwelo oluza kuthatyathwa kufikelele kwimfuneko, i-slurry yokucoca iyahlukana. Ngena, qhubela phambili. Umgangatho othe ngqo wokugquma (indima isetyenziswa ngokuqhelekileyo kwisikrini sokucoca isikrini. Ubukhulu be-millimeter layer ngokuqhelekileyo 3-80. Kwimveliso yangempela yesikrini sokucoca, ikhekhe inokunqunyulwa ngokuqhubekayo (njengomshini we-vacuum filter filter cake), onokuthi ube mtsha Umbhede wokucoca uzinzile kwaye uzinzile.

(2)Ukugqobhoza:

I-precipitation filtration yenziwa ngamanyathelo amabini: ukugubungela kwangaphambili kunye nokongeza: ubukhulu be-pre-coating ngokuqhelekileyo bu-2-3 mm. Umsebenzi oyintloko kukukhusela izinto zokucoca ekuthabatheni ukungcola, kwaye ngexesha elifanayo liguqule libe yingubo yepolymer xa yongezwa kwisihlunu. I-pre-coating ngokuqhelekileyo i-2-3 mm. Ubunzima kunye nesakhiwo sibalulekile kuyo yonke inkqubo. Ngokobume bezinto zokucoca (i-viscosity, i-particle kunye nomxholo, i-compressible filterability of particles, njl.), umsebenzisi unokusebenzisa ezi nkqubo zilandelayo:

(1) Ukugquma kwangaphambili

I-pre-coating yenziwa yimpembelelo yokudibanisaukuhluza uncedo lokucocaphakathi. Ewe: Thintela isihluzo esiphakathi (ulwelo oluza kuhluzwa) kumasuntswana kwisihluzo; i-filtrate inokufumaneka ekuqaleni kokucoca; isihluzo esiphakathi kulula ukusitshixa. Xa i-coating yangaphambili, uncedo oluthile lokucoca kunye nolwelo olucacileyo (okanye amanzi okucoca i-disinfection) lulinganiswe kwi-5-10% (i-mass ratio) yokumiswa kwi-tank yangaphambili, kwaye i-pre-coating pre-coating yenziwe kwi-filter medium ngokusebenzisa ipompo yokujikeleza. ukutyabeka. Ubukhulu becala lokucoca isihluzo simalunga ne-2-4MM ubukhulu (idosi yoncedo lokucoca kwangaphambili yi-700-1000G/m²). Isihluzi somoya esiphindwe kabini sifuna i-8-15CM yangaphambili. Iimfuno zokuhluza ezicacileyo, kunye ne-low-viscosity fluid (malunga ne-1CP), izinga lokuhamba kwe-pre-coating limalunga ne-40L/m², kwaye i-low-viscosity fluid pre-coating rate rate iyancitshiswa ngokufanelekileyo.

(2) Emva kokongeza uncedo lokucoca ukucoca kunye nokugubungela kwangaphambili, emva kokuba i-powder filter ingena kwisihlunu, kuyimfuneko yokongeza i-filter aid ye-0.1-2.0% ngobunzima be-slurry. Kwinkqubo yokucoca, uncedo lokucoca kunye neengqungquthela zokungcola kwi-slurry yokucoca zongezwa kumatshini wokucoca ngokuhambelanayo. Isixa esongezelelweyo sigcina isixa kunye nokunyanzeliswa kweengqungquthela ezenziweyo. Ukungahlambuluki kunye nesantya esiphezulu soxinzelelo, isixa soncedo lokucoca sihambelana nokunyuka. Ukongezwa kwesihluzi kufuneka kwenziwe xa uxinzelelo lokucoca lufikelela kuxinzelelo. Isikrini sokucoca ngokusisiseko esizaliswe sisihluzo sekhusi sivumela ukugqitywa kwesithuba sokucoca ukufunxa. Kweli nqanaba kumjikelo wokucoca, isikrini sokucoca singena kwinqanaba le-adsorption.

(3) Yongeza ukuhluza ngokuthe ngqo:

Uncedo lokucoca kunye nezinto eziqinileyo kwi-slurry yokucoca zifakwe kwi-pre-layer okanye umaleko wokucoca ukwenza umaleko omtsha wokucoca, ukuze isihluzo sigcine imeko ezinzileyo. Isantya sokuhluza. Ngeli xesha, i-particle size ye-Wu Jia's filter aid igqitywe kuphela yimpawu zemilo kwi-slurry yokucoca, kwaye ayichatshazelwa kukwenziwa kwesihluzi.
