(1)Ukuhlunga isendlalelo sokuhlunga:

I-adsorbent emuncwa i-filtrate efakwe ngaphambili kanye namanzi ahlanziwe ahlanjululwe noma i-slurry yesihlungi ixutshwa ekumisweni ebhakedeni lokuphakela, futhi ngemva kokuba ukugxila koketshezi oluzomuncwa kufinyelela imfuneko, i-slurry yesihlungi iyahlukaniswa. Ngena, qhubeka kusenesikhathi. I-medium eqondile yokugqoka (indima ngokuvamile iyasebenza esikrinini sokuhlunga sokunwetshwa. Ubukhulu bengqimba ye-millimeter ngokuvamile buyi-3-80. Ekukhiqizeni kwangempela kwesikrini sokuhlunga, ikhekhe lingabuye linqunywe ngokuqhubekayo (njengomshini wekhekhe wokuhlunga isigubhu), okungaba okusha Umbhede wokuhlunga uzinzile futhi uzinzile.

(2)I-Percolation:

Ukuhlunga kwemvula kwenziwa ngezinyathelo ezimbili: ukumbozwa kwangaphambili nokwengeza: ubukhulu be-pre-coating ngokuvamile buyi-2-3 mm. Umsebenzi oyinhloko ukuvikela izinto zokuhlunga ekumunceni ukungcola, futhi ngesikhathi esifanayo ziguqule zibe i-polymer coating uma yengezwa kusihlungi. I-pre-coating coating ngokuvamile i-2-3 mm. Ukushuba kanye nesakhiwo kubalulekile kuyo yonke inqubo. Ngokwemvelo yezinto zokuhlunga (i-viscosity, izinhlayiya nokuqukethwe, ukuhlunga okucindezelwayo kwezinhlayiya, njll.), umsebenzisi angasebenzisa izinqubo ezilandelayo:

(1) Ukumboza ngaphambili

I-pre-coating yakhiwe umphumela wokuhlanganisa weisihlungi sosizo lokuhlungaphakathi nendawo. Yebo: Vimbela isihlungi (uketshezi oluzohlungwa) ezinhlayiyeni ezisesihlungini; i-filtrate ingatholakala ekuqaleni kokuhlunga; isihlungi kulula ukukhiya. Uma ukufakwa kuqala, usizo oluthile lwesihlungi kanye noketshezi olucacile (noma amanzi okukhipha amagciwane) kuhlukaniswa ngokumiswa kwe-5-10% (isilinganiso sobuningi) ku-tank yangaphambili yokugqoka, futhi ukugqoka kwangaphambili okuhle nokuzinzile kwakhiwa endaweni yokuhlunga ngokusebenzisa iphampu yokujikeleza. enamathela. Ugqinsi lwangaphambi kokumbozwa komshini wokuhlunga luwugqinsi olucishe lube ngu-2-4MM (umthamo wosizo lwesihlungi sokumbozwa kusengaphambili ngu-700-1000G/m²). Isihlungi somoya esikabili sidinga ukumbozwa ngaphambilini okungu-8-15CM. Izidingo zokuhlunga ezisobala, ezinoketshezi lwe-viscosity ephansi (cishe i-1CP), izinga lokugeleza elijwayelekile langaphambi kokumbozwa licishe libe ngu-40L/m², futhi izinga lokugeleza lokumbozwa kwangaphambili kwe-viscosity eliphansi liyehliswa ngokufanele.

(2) Ngemva kokwengeza usizo lokuhlunga ukuhlunga kanye nokugqoka kwangaphambili, ngemva kokuba i-powder yokuhlunga ingene esihlungini, kuyadingeka ukwengeza usizo lokuhlunga lwe-0.1-2.0% ngesisindo se-slurry. Enqubweni yokuhlunga, usizo lokuhlunga kanye nezinhlayiya zokungcola ku-slurry yesihlungi zengezwa emshinini wokuhlunga ngokufanayo. Inani elingeziwe ligcina inani kanye nokucindezelwa kwezinhlayiya ezakhiwe. Ukungcola okunezinga eliphezulu lokuminyanisa, inani lokwengezwa kosizo lwesihlungi lihambisana nokunyuka. Ukwengezwa kwesihlungi kufanele kwakhiwe lapho ingcindezi yokuhlunga ifinyelela ukucindezela. Isikrini sokuhlunga ngokuyisisekelo esigcwaliswe ngesikrini sokuhlunga sivumela ukuqedwa kwesikhala sesihlungi sokumunca. Kuleli qophelo kumjikelezo wokuhlunga, isikrini sokuhlunga singena esigabeni se-adsorption.

(3) Engeza ukuhlunga ngokuqondile:

Usizo lwesihlungi nezinto eziqinile ku-slurry yesihlungi zifakwa ndawonye kusendlalelo sangaphambili noma isendlalelo sesihlungi ukuze kwakhe ungqimba lwesihlungi esisha, ukuze isihlungi sikwazi ukugcina isimo esizinzile. Isivinini sokuhlunga. Ngalesi sikhathi, usayizi wezinhlayiyana zosizo lwesihlungi se-Wu Jia unqunywa kuphela izici zomumo ku-slurry yesihlungi, futhi akuthintwa ukwakheka kwesihlungi.
