Ingxowa elukiweyo engama-25kg/idrama yebhodi yephepha engama-25kg/idrama yesinyithi engama-200L okanye ngokwesicelo somthengi.
Iimpawu zeZakhiwo zeI-Alumina esebenzayo
I-alumina esebenzayo ineempawu zomthamo omkhulu wokufunxa, indawo enkulu ethile, amandla aphezulu, kunye nokuzinza okuhle kobushushu. Inamandla amakhulu, yi-desiccant engenabungozi, engaboliyo, kwaye amandla ayo azinzileyo aphezulu. Isetyenziswa njenge-adsorbent, desiccant, catalyst kunye nomthwali kwiinkqubo ezininzi zokusabela ezifana nepetroleum, isichumiso seekhemikhali kunye nomzi-mveliso weekhemikhali.
I-alumina esebenzayo yenye yezona mveliso zeekhemikhali ezingaphiliyo ezisetyenziswa kakhulu ehlabathini. Iimpawu ze-alumina esebenzayo zichazwe ngezantsi: I-alumina esebenzayo inozinzo oluhle kwaye ifanelekile njenge-desiccant, i-catalyst carrier, i-agent yokususa i-fluorine, i-pressure swing adsorbent, i-arhente yokuvuselela i-hydrogen peroxide, njl. I-alumina esebenzayo isetyenziswa kakhulu njenge-catalyst kunye ne-catalyst carrier.
I-alumina esebenzayo isetyenziswa njenge-desiccant, esetyenziswa kakhulu kwizixhobo zokomisa uxinzelelo lomoya kwimizi-mveliso, izixhobo zokomisa uxinzelelo lomoya zinoxinzelelo olusebenzayo, ngokubanzi zingaphantsi kwe-0.8Mpa, nto leyo efuna ukuba umlinganiselo we-alumina osebenzayo ube namandla alungileyo oomatshini, ukuba amandla oomatshini aphantsi kakhulu, kulula ukuwugawula, umxube wepowder namanzi uya kuyivala ngqo imibhobho yezixhobo, ngoko ke, uphawu olubalulekileyo lwe-alumina esebenzayo esetyenziswa njenge-desiccant ngamandla, izixhobo zokomisa uxinzelelo lomoya, ngokubanzi iitanki ezimbini, iitanki ezimbini zisebenza ngokutshintshana, ngokwenene yi-adsorption saturation → inkqubo yomjikelo wohlalutyo, i-desiccant ikakhulu ngamanzi okugawula, kodwa phantsi kweemeko zokusebenza ezingokoqobo, umthombo wezixhobo zokomisa uxinzelelo lomoya uya kuba neoyile, umhlwa kunye nokunye ukungcola. Ezi zinto ziya kuchaphazela ngqo ubomi benkonzo ye-activated adsorbent ye-alumina, kuba i-activated alumina zizinto zokugawula ezinemingxuma, i-natural adsorption polarity yamanzi, i-oyile adsorption nayo ilungile kakhulu, kodwa ioyile iya kuzixhuma ngqo i-activated alumina adsorption pore, ukuze ukulahleka kweempawu zokugawula, kukho Ukuba umhlwa, umhlwa emanzini, unamathele kumphezulu we-alumina esebenzayo, uya kwenza i-alumina esebenzayo ilahlekelwe ngqo ngumsebenzi, ngoko ke xa i-alumina esebenzayo isetyenziswa njenge-desiccant, zama ukuphepha ukudibana neoyile, umhlwa, ubomi bokusetyenziswa ngokubanzi be-alumina esebenzayo buyiminyaka eli-1 ukuya kweyi-3, ukusetyenziswa okwenyani kuya kuba yindawo yokomisa igesi ukuze kugqitywe ukuba ithathe indawo ye-alumina esebenzayo. Ubushushu bokuvuselelwa kwe-alumina esebenzayo buphakathi kwe-180 ~ 350℃. Ngokubanzi, ubushushu be-alumina tower esebenzayo bunyuka bufike kwi-280℃ kangangeeyure ezi-4. I-alumina esebenzayo isetyenziswa njengearhente yonyango lwamanzi, kwaye isisombululo se-aluminium sulfate sisetyenziswa njenge-regenerator. Uxinzelelo lwesisombululo se-alumina sulfate regenerator yi-2 ~ 3%, i-alumina esebenzayo emva kokufunxwa kwe-adsorption ifakwa kwisisombululo se-alumina sulfate, silahle isisombululo, sihlambe ngamanzi acocekileyo amaxesha ama-3 ukuya kwama-5. Emva kokusetyenziswa ixesha elide, umphezulu we-alumina osebenzayo unombala otyheli kwaye isiphumo sokuphuma kwe-fluorination sinciphile, okubangelwa kukufunxwa kokungcola. Inganyangwa nge-3% ye-hydrochloric acid okwesihlandlo esinye ize ivuselelwe ngendlela engasentla.
