Cov khoom no yog siv rau kev sib sib zog nqus ziab ntawm cov roj los yog kua theem ntawm petrochemicals thiab ziab ntawm cov twj paj nruag.
25kg woven hnab / 25kg ntawv board nruas / 200L hlau nruas los yog ib tus neeg thov.
Tus Txheej Txheem Khoom NtawmActivated Alumina
Activated alumina muaj cov yam ntxwv ntawm lub peev xwm loj adsorption, thaj chaw loj tshwj xeeb, lub zog siab, thiab zoo thermal stability.yam khoom.Nws muaj kev sib raug zoo, tsis muaj tshuaj lom, tsis muaj corrosive zoo desiccant, thiab nws muaj peev xwm zoo li qub.Nws yog siv los ua adsorbent, desiccant, catalyst thiab carrier hauv ntau cov txheej txheem tshuaj tiv thaiv xws li roj av, tshuaj chiv thiab tshuaj lom neeg kev lag luam.
Activated alumina yog ib qho ntawm cov khoom siv tshuaj inorganic tshaj plaws hauv ntiaj teb.Cov khoom ntawm activated alumina tau piav qhia hauv qab no: Activated alumina muaj kev ruaj ntseg zoo thiab tsim nyog raws li lub tshuab desiccant, catalyst carrier, fluorine tshem tawm tus neeg sawv cev, lub siab viav vias adsorbent, tshwj xeeb regeneration agent rau hydrogen peroxide, thiab lwm yam. Activated alumina yog dav siv. raws li catalyst thiab catalyst cab kuj.
Activated alumina yog siv los ua cov desiccant, feem ntau yog siv rau hauv cov khoom siv cua siab kom qhuav, cov khoom siv cua siab kom qhuav muaj qhov ua haujlwm siab, feem ntau qis dua 0.8Mpa, uas yuav tsum muaj qhov sib piv ntawm cov activated alumina kom muaj lub zog zoo txhua yam, yog tias lub zog muaj zog heev. Tsawg, nws yooj yim rau hmoov, hmoov thiab dej sib xyaw ua ke yuav ncaj qha thaiv cov khoom siv kav dej, yog li, Qhov taw qhia tseem ceeb ntawm activated alumina siv los ua cov desiccant yog lub zog, cov khoom siv cua tshuab ziab khaub ncaws, feem ntau yog ob lub tso tsheb hlau luam, ob lub tso tsheb hlau luam ua haujlwm sib hloov, yog qhov tseeb. adsorption saturation → analytic cycle txheej txheem, desiccant yog tsuas yog adsorption dej, tab sis nyob rau hauv qhov tseeb ua hauj lwm tej yam kev mob, huab cua siab drying khoom los ntawm huab cua yuav muaj roj, xeb thiab lwm yam impurities, Cov yam tseem ceeb no yuav cuam tshuam ncaj qha rau kev pab cuam lub neej ntawm activated alumina adsorbent, vim hais tias activated alumina yog cov khoom ntxeem tau adsorption, ntuj adsorption polarity ntawm dej, roj adsorption kuj zoo heev, tab sis cov roj yuav ncaj qha ntsaws activated alumina adsorption pore, yog li ntawd qhov poob ntawm adsorption yam ntxwv, muaj xeb, xeb hauv dej, txuas rau saum npoo activated alumina, Yuav ua rau activated alumina ncaj qha poob kev ua si, yog li nyob rau hauv activated alumina li desiccant siv, sim kom tsis txhob muaj kev sib cuag nrog roj, xeb, activated alumina adsorbent li desiccant dav siv lub neej ntawm 1 ~ 3 xyoo, qhov tseeb siv yuav ua kom qhuav roj. dew taw tes los txiav txim seb puas yuav hloov tau alumina.Qhov kub thiab txias ntawm activated alumina yog nruab nrab ntawm 180 ~ 350 ℃.Feem ntau, cov activated alumina ntauwd kub nce mus rau 280 ℃ rau 4 teev.Activated alumina yog siv los ua tus neeg saib xyuas dej, thiab cov tshuaj txhuas sulfate yog siv los ua regenerator.Qhov kev daws teeb meem ntawm aluminium sulfate regenerator yog 2 ~ 3%, lub tshuab txais alumina tom qab adsorption saturation yog muab tso rau hauv aluminium sulfate tov, pov tseg cov tshuaj, ntxuav nrog dej huv 3 ~ 5 zaug.Tom qab siv mus ntev, lub tshuab ua kom alumina nto yog daj xim av thiab cov nyhuv defluorination txo, uas yog tshwm sim los ntawm adsorption ntawm impurities.Nws tuaj yeem kho nrog 3% hydrochloric acid rau 1 zaug thiab rov tsim dua los ntawm txoj kev saum toj no.
