Le mveliso isetyenziselwa ukomiswa okunzulu kwegesi okanye isigaba solwelo sepetrochemicals kunye nokomisa izixhobo.
25kg ibhegi elukiweyo / 25kg iphepha igubu ibhodi / 200L igubu lentsimbi okanye isicelo umthengi ngamnye.
I-alumina esebenzayo ineempawu zomthamo omkhulu we-adsorption, indawo enkulu yendawo ethile, amandla aphezulu, kunye nokuzinza okuhle kwe-thermal. into. Inobudlelwane obuqinileyo, i-desiccant engeyona inetyhefu, i-non-corrosive, kunye nomthamo wayo we-static uphezulu. Isetyenziswe njenge-adsorbent, i-desiccant, i-catalyst kunye ne-carrier kwiinkqubo ezininzi zokuphendula ezifana ne-petroleum, i-chemical fertilizer kunye ne-shishini lemichiza.
I-alumina esebenzayo yenye yezona mveliso zisetyenziswa kakhulu kwimichiza ye-inorganic emhlabeni. Iimpawu ze-alumina esebenzayo zichazwe ngezantsi: i-alumina esebenzayo inozinzo oluhle kwaye ifanelekile njenge-desiccant, i-catalyst carrier, i-agent yokususa i-fluorine, i-adsorbent yoxinzelelo, i-agent ekhethekileyo yokuhlaziya i-hydrogen peroxide, njl njl. njengecatalyst kunye necatalyst carrier.
I-alumina esebenzayo isetyenziswa njenge-desiccant, isetyenziswa ikakhulu kwizixhobo zokomisa uxinzelelo lomoya, izixhobo zokomisa uxinzelelo lomoya zinoxinzelelo olusebenzayo, ngokubanzi ngaphantsi kwe-0.8Mpa, efuna umlinganiselo osebenzayo we-alumina ube namandla omatshini, ukuba amandla omatshini angaphezulu kakhulu. ephantsi, kulula ukuba ngumgubo, umgubo kunye nokudibanisa kwamanzi kuya kuthintela ngokuthe ngqo umbhobho wesixhobo, ngoko ke, isalathisi esibalulekileyo se-alumina esebenzayo esetyenziswa njenge-desiccant ngamandla, izixhobo zomoya zokomisa umoya, ngokubanzi iitanki ezimbini, iitanki ezimbini zisebenza ngokutshintshanayo, ngokwenene. i-adsorption saturation → inkqubo yokuhlalutya umjikelo, i-desiccant ikakhulu i-adsorption yamanzi, kodwa phantsi kweemeko ezisebenzayo, izixhobo zomoya zokomisa umoya ziya kuba neoyile, umhlwa kunye nobunye ukungcola, Ezi zinto ziya kuchaphazela ngqo ubomi benkonzo ye-alumina adsorbent esebenzayo, kuba ivuliwe. I-alumina yimpahla ye-adsorption ene-porous, i-adsorption polarity yendalo yamanzi, i-oyile i-adsorption nayo ilungile kakhulu, kodwa i-oyile iya kuyivala ngokuthe ngqo i-alumina adsorption pore, ukuze ilahleko yeempawu ze-adsorption, kukho irusi, i-rust emanzini, encanyathiselwe kumphezulu we-adsorption. I-alumina esebenzayo, iya kwenza i-alumina esebenzayo ilahlekelwe ngumsebenzi ngokuthe ngqo, ngoko ke kwi-alumina esebenzayo njengokusetyenziswa kwe-desiccant, zama ukuphepha ukudibanisa neoli, i-rust, i-alumina esebenzayo i-adsorbent njenge-desiccant yobomi bokusetyenziswa ngokubanzi be-1 ~ 3 iminyaka, ukusetyenziswa kwangempela kuya kuba kukomisa igesi. indawo yombethe ukwenza isigqibo sokuba ithathe indawo yealumina evuliweyo. Ubushushu bokuhlaziywa kwe-alumina esebenzayo buphakathi kwe-180 ~ 350 ℃. Ngokubanzi, ubushushu be-alumina esebenzayo bunyuka ukuya kuma-280 ℃ iiyure ezi-4. I-alumina esebenzayo isetyenziswa njenge-arhente yonyango lwamanzi, kwaye isisombululo se-aluminium sulfate sisetyenziswa njenge-regenerator. Uxinzelelo lwesisombululo se-aluminium sulfate regenerator yi-2 ~ 3%, i-alumina esebenzayo emva kwe-adsorption saturation ifakwe kwisisombululo se-aluminium sulfate, ukulahla isisombululo, hlamba ngamanzi acocekileyo 3 ~ 5 amaxesha. Emva kokusetyenziswa kwexesha elide, indawo ye-alumina esebenzayo inombala obomvu obomvu kwaye umphumo we-defluorination uyancitshiswa, obangelwa ukubhengezwa kokungcola. Inokunyangwa nge-3% ye-hydrochloric acid kwi-1 ixesha kwaye iphinde ihlaziywe ngale ndlela ingentla.
