Talosaga/Tapa'iina
O lenei oloa e faʻaaogaina mo le faʻagogo loloto o le kesi poʻo le vai vai o petrochemicals ma faʻamago mea faigaluega.
25kg taga lalaga / 25kg pepa pa'u laupapa / 200L u'amea pa'u po o talosaga a tagata faatau.
O Meatotino Fausia OAlumina fa'agaoioia
Alumina fa'agaoioia o lo'o i ai uiga o le tele o le adsorption capacity, tele fa'apitoa i luga o le fogaeleele, malosi maualuga, ma le mautu lelei o le vevela. mea. E i ai se sootaga malosi, e le oona, e le corrosive aoga desiccant, ma lona gafatia static e maualuga. E fa'aaogaina e pei o le adsorbent, desiccant, catalyst ma le va'ava'a i le tele o gaioiga fa'afoliga e pei o le suau'u, vaila'au vaila'au ma alamanuia vaila'au.
O le alumina fa'agaoioia o se tasi lea o mea fa'aonaponei fa'aoga fa'aogaina i le lalolagi. O mea totino o alumina faʻagaoioia o loʻo faʻamatalaina i lalo: O le alumina faʻagaoioia e lelei le mautu ma e talafeagai e avea o se desiccant, o se faʻapipiʻi faʻapipiʻi, o se mea e aveese ai le fluorine, o se faʻapipiʻi faʻamalosi, o se sui faʻafouina faʻapitoa mo le hydrogen peroxide, ma isi. e pei o le catalyst ma le catalyst carrier.
Alumina fa'agaoioia o lo'o fa'aaogaina e pei o se desiccant, e masani lava ona fa'aaogaina i masini fa'agogo fa'atosina ea, masini fa'agogo ea o lo'o i ai le mamafa galue, e masani lava i lalo ole 0.8Mpa, lea e mana'omia ai le fua fa'atatau o le alumina fa'agaoioia e maua ai se malosi fa'ainisinia lelei, pe a fai o le malosi fa'ainisinia e tele. maualalo, e faigofie ona paʻu, paʻu ma vai tuufaatasiga o le a poloka saʻo le pipeline meafaigaluega, o lea, O se faailoga taua o alumina faʻaaogaina o loʻo faʻaaogaina e pei o se desiccant o le malosi, masini faʻagogo mamafa o le ea, e masani lava lua tane, lua tane galue e sui, o le mea moni. a adsorption saturation → analytic faagasologa taamilosaga, desiccant o le tele lava adsorption vai, ae i lalo o tulaga galue moni, ea mamafa faamago meafaigaluega puna ea o le ai ai suauu, ele ma isi eleelea, O nei mea taua o le a aafia tuusao le ola auaunaga o alumina faagaioiina adsorbent, ona ua faagaoioia. alumina o mea adsorption porous, polarity adsorption natura o le vai, adsorption suauu e lelei tele foi, ae o le suauu o le a faʻapipiʻi saʻo faʻagaoioia alumina adsorption pore, ina ia leiloa uiga adsorption, o loʻo i ai le ele, ele i le vai, faʻapipiʻi i luga o le alumina fa'aagaoioia, O le a faia alumina fa'agaoioia sa'o leiloa le gaioiga, o lea i le alumina fa'agaoioia e pei o le fa'aoga fa'amago, taumafai e aloese mai le fa'afeso'ota'i ma le suau'u, ele, alumina fa'aagaoioia adsorbent e pei o le ola fa'aoga lautele o le 1 ~ 3 tausaga, o le fa'aoga moni o le a fa'amago kesi. le sau e filifili ai pe sui le alumina fa'agaoioia. Ole vevela ole fa'afouina ole alumina fa'agaoioia ile va ole 180 ~ 350℃. E masani lava, o le vevela o le alumina o loʻo faʻaaogaina e siitia i le 280 ℃ mo le 4 itula. O le alumina faʻaaogaina e faʻaaogaina e fai ma sui o le vai, ma faʻaaogaina le aluminium sulfate solution e fai ma toe faʻafouina. O le faʻatonuga o le faʻaogaina o le aluminium sulfate regenerator o le 2 ~ 3%, o le alumina faʻaagaoioia pe a uma ona tuʻuina le saturation adsorption i le faʻamaʻi alumini sulfate solution, lafoai le fofo, fufulu i le vai mama 3 ~ 5 taimi. A maeʻa le faʻaaogaina umi, o le alumina faʻaaogaina e lanu samasama enaena ma faʻaitiitia le aafiaga defluorination, lea e mafua mai i le adsorption o mea leaga. E mafai ona togafitia i le 3% hydrochloric acid mo le 1 taimi ona toe faʻafouina lea i le auala o loʻo i luga.
