I-Alumina Ecushiwe Yokwelapha Amanzi
Isingeniso Somkhiqizo
Umkhiqizo uyinto emhlophe, eyindilinga ene-porous enempahla engenabuthi, engenaphunga, engancibiliki emanzini ne-ethanol. Ubukhulu bezinhlayiyana buyiyunifomu, ubuso bushelelezi, amandla omshini aphakeme, ikhono lokumunca umswakama linamandla futhi ibhola alihlukaniswanga ngemva kokumunca amanzi.
Usayizi wengxenye ungaba ngu-1-3mm, 2-4mm/3-5mm noma ube mncane kakhulu njengo-0.5-1.0mm. Inendawo enkulu yokuxhumana enamanzi nendawo ethize ephakeme kuno-300m²/g, inenani elikhulu ama-microspores futhi angaqinisekisa ukukhanga okuqinile kanye nevolumu ephezulu ye-defluorination ku-fluorinnion emanzini.
I-alumina ye-hydrogen peroxide ineziteshi eziningi ze-capillary kanye nendawo enkulu, engasetshenziswa njenge-adsorbent, i-desiccant kanye ne-catalyst. Ngasikhathi sinye, kunqunywa futhi ngokuya nge-polarity yento ye-adsorbed. Inobudlelwane obuqinile bamanzi, ama-oxides, i-acetic acid, i-alkali, njll. I-alumina ecushiwe iwuhlobo lwe-desiccant ejulile yamanzi kanye ne-adsorbent yama-adsorbing polar molecules. .
Ngaphansi kwezimo ezithile zokusebenza nezimo zokuvuselela, ukujula kokoma kwayo kuphakeme njengezinga lokushisa lamazolo elingaphansi kuka -40℃, futhi iyi-desiccant ephumelelayo yokomisa okujulile kwamanzi okulandelela. Isetshenziswa kakhulu embonini ye-petrochemical, ukomiswa kwesigaba segesi nesamanzi, ukomiswa kwemboni yendwangu, imboni yokukhiqiza umoya-mpilo nomoya wensimbi othomathikhi, i-press swing adsorption embonini yokuhlukanisa umoya, njll. Ngenxa yokushisa okuphezulu kwenetha kwesendlalelo se-monomolecular adsorption, ifaneleka kakhulu kumadivayisi okuvuselela angenakushisa. I-alumina ye-hydrogen peroxide iyizinhlayiya ezimhlophe eziyindilinga eziyindilinga ezinosayizi wezinhlayiyana ezifanayo, indawo ebushelelezi, amandla aphezulu emishini kanye ne-hygroscopicity eqinile. Yenziwe nge-alumina ehlanzekile ngokulungiswa kwesayensi kanye nokuqedwa kwe-catalytic. Ingasetshenziswa njengesikhiphi se-fluoride emanzini aphezulu e-fluoride, iyenze ibe i-adsorbent yamangqamuzana enendawo enkulu ethile. Uma inani le-pH kanye ne-alkalinity yamanzi aluhlaza iphansi, umthamo wokukhipha i-fluorine uphezulu, mkhulu kuno-3.0mg/g. Ingasetshenziselwa ukususwa kwe-fluorine, ukususwa kwe-arsenic, ukuchithwa kwendle nokuqeda iphunga lamanzi okuphuza kanye nemishini yezimboni.

Isicelo/Ukupakisha
Ingasetshenziswa njenge-ejenti ye-defluorination emanzini. Ikakhulukazi uma inani le-PH kanye ne-alkalinity yamanzi kukodwa, ivolumu ye-defluorination ingaba ngaphezu kuka-4.0mg/g. Ingasetshenziselwa ukususa i-arsenic emanzini okuphuza.
25kg isikhwama nokwelukiweyo / 25kg iphepha ibhodi isigubhu / 200L iron sigubhu noma isicelo ngamunye ikhasimende.
