Kugwiritsa Ntchito/Kulongedza
Chogulitsachi chimagwiritsidwa ntchito poumitsa mpweya kapena madzi a petrochemicals ndi kuumitsa zida.
Chikwama cholukidwa cha 25kg/25kg ng'oma ya bolodi la pepala/200L ng'oma yachitsulo kapena malinga ndi pempho la kasitomala.
Kapangidwe kakeAluminiyamu yoyendetsedwa
Alumina yogwiritsidwa ntchito ili ndi mphamvu yayikulu yothira madzi, malo akuluakulu apadera, mphamvu zambiri, komanso kukhazikika bwino kwa kutentha. Ili ndi mphamvu yamphamvu, ndi desiccant yopanda poizoni, yogwira ntchito bwino, ndipo mphamvu yake yosasunthika ndi yayikulu. Imagwiritsidwa ntchito ngati adsorbent, desiccant, catalyst komanso chonyamulira munjira zambiri zochitira zinthu monga mafuta, feteleza wa mankhwala ndi makampani a mankhwala.
Alumina yogwira ntchito ndi imodzi mwa mankhwala osapangidwa omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi. Makhalidwe a alumina yogwira ntchito afotokozedwa pansipa: Alumina yogwira ntchito imakhala yokhazikika bwino ndipo ndi yoyenera ngati desiccant, catalyst carrier, fluorine removal agent, pressure swing adsorbent, hydrogen peroxide yapadera, ndi zina zotero. Alumina yogwira ntchito imagwiritsidwa ntchito kwambiri ngati catalyst ndi catalyst carrier.
Alumina yogwiritsidwa ntchito imagwiritsidwa ntchito ngati desiccant, yomwe imagwiritsidwa ntchito kwambiri muzipangizo zowumitsira mpweya, zida zowumitsira mpweya zimakhala ndi kuthamanga kwa ntchito, nthawi zambiri zimakhala pansi pa 0.8Mpa, zomwe zimafuna kuti chiŵerengero cha alumina chogwiritsidwa ntchito chikhale ndi mphamvu yabwino yamakina, ngati mphamvu yamakina ndi yotsika kwambiri, n'zosavuta kuipanga ufa, kuphatikiza ufa ndi madzi kudzatseka mwachindunji payipi ya zida, kotero, chizindikiro chofunikira cha alumina yogwiritsidwa ntchito ngati desiccant ndi mphamvu, zida zowumitsira mpweya, nthawi zambiri matanki awiri, matanki awiri amagwira ntchito mosinthana, kwenikweni ndi kukhuta kwa adsorption → njira yowunikira, desiccant makamaka ndi madzi okhudzidwa, koma pansi pa mikhalidwe yogwira ntchito yeniyeni, mpweya wochokera kuzipangizo zowumitsira mpweya udzakhala ndi mafuta, dzimbiri ndi zodetsa zina. Zinthu izi zidzakhudza mwachindunji moyo wa ntchito ya alumina yothandizidwa, chifukwa alumina yogwiritsidwa ntchito ndi zinthu zotsekemera, madzi achilengedwe otsekemera, mafuta otsekemera nawonso ndi abwino kwambiri, koma mafuta adzatsegula mwachindunji pore yotsekemera ya alumina yoyambitsidwa, kotero kuti kutayika kwa makhalidwe otsekemera, pali Ngati alumina yogwiritsidwa ntchito ndi dzimbiri, yomwe imalumikizidwa pamwamba pa alumina yogwiritsidwa ntchito, imapangitsa alumina yogwiritsidwa ntchito kutayikira mwachindunji, kotero ngati alumina yogwiritsidwa ntchito ngati desiccant ikugwiritsidwa ntchito, yesetsani kupewa kukhudzana ndi mafuta, dzimbiri, alumina yogwiritsidwa ntchito ngati desiccant nthawi yogwiritsidwa ntchito yonse ya zaka 1 ~ 3, ntchito yeniyeni idzakhala powumitsa mpweya kuti musankhe ngati mungayike alumina yogwiritsidwa ntchito. Kutentha kokonzanso kwa alumina yogwiritsidwa ntchito kuli pakati pa 180 ~ 350℃. Nthawi zambiri, kutentha kwa nsanja ya alumina yogwiritsidwa ntchito kumakwera kufika pa 280℃ kwa maola 4. Alumina yogwiritsidwa ntchito imagwiritsidwa ntchito ngati chothandizira kuchiza madzi, ndipo yankho la aluminiyamu sulfate limagwiritsidwa ntchito ngati chobwezeretsanso. Kuchuluka kwa yankho la aluminium sulfate regenerator ndi 2 ~ 3%, alumina yogwiritsidwa ntchito pambuyo pa kudzazidwa imayikidwa mu aluminium sulfate solution, taya yankho, sambani ndi madzi oyera nthawi 3 ~ 5. Pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali, pamwamba pa alumina yogwiritsidwa ntchito ndi bulauni wachikasu ndipo zotsatira za defluorination zimachepa, zomwe zimachitika chifukwa cha kulowetsedwa kwa zonyansa. Itha kuchiritsidwa ndi 3% hydrochloric acid kwa nthawi imodzi kenako nkubwezeretsedwanso pogwiritsa ntchito njira yomwe ili pamwambapa.
