Ukadaulo woyaka wa Catalytic
1 Technical Background
Kukula kwachuma ndi chikhalidwe cha anthu komanso kufunikira kwa mafakitale kumapangitsa ukadaulo wothandizira, makamaka ukadaulo wowotcha, kukhala njira yofunikira yaukadaulo wamafakitale, komanso ndikusintha kwa moyo wa anthu komanso kukula kwa kufunikira, makampani othandizira apitiliza kulowa masauzande ambiri. m'nyumba, m'miyoyo ya anthu. Kafukufuku wokhudzana ndi kuyaka kwamphamvu kudayamba kuchokera pomwe anapeza mphamvu ya platinamu pa kuyaka kwa methane. Kuyaka kwa catalytic kumagwira ntchito yofunika kwambiri pakuwongolera kuyaka, kuchepetsa kutentha kwazomwe zimachitika, kulimbikitsa kuyaka kwathunthu, ndikuletsa mapangidwe azinthu zapoizoni komanso zovulaza, ndipo kwagwiritsidwa ntchito kwambiri pazinthu zambiri zamakampani komanso moyo watsiku ndi tsiku.
2.Chofunika ndi ubwino wa catalytic combustion
Kuwotcha kothandizira ndikofanana ndi gasi-olimba gawo lothandizira, kumachepetsa mphamvu yoyambitsa zomwe zimachitika mothandizidwa ndi chothandizira, kotero kuti ndi kuyaka kopanda malawi pa kutentha kochepa kwa 200 ~ 300 ℃. The makutidwe ndi okosijeni wa zinthu organic kumachitika pamwamba chothandizira olimba, pamene akupanga CO2 ndi H2O, ndi kutulutsa kutentha kwambiri, chifukwa otsika makutidwe ndi okosijeni anachita kutentha. Chifukwa chake, N2 mumlengalenga imalepheretsa kwambiri kupanga kutentha kwa NOx. Komanso, chifukwa chosankha chothandizira cha chothandizira, ndizotheka kuchepetsa makutidwe ndi okosijeni a mankhwala okhala ndi nayitrogeni (RNH) mumafuta, kotero kuti ambiri aiwo amapanga ma molekyulu nayitrogeni (N2).
Poyerekeza ndi kuyaka kwamoto kwachikhalidwe, kuyaka kothandizira kuli ndi zabwino zambiri:
(1) Kutentha kwamoto kumakhala kochepa, mphamvu yogwiritsira ntchito mphamvu ndi yochepa, kuyaka kumakhala kosavuta kukhazikika, ndipo ngakhale makutidwe ndi okosijeni amatha kutha popanda kutengera kutentha kwakunja pambuyo pa kutentha.
(2) Kuyeretsa kwakukulu, kutsika kwa mpweya woipa (monga NOx ndi zinthu zosakwanira zoyaka moto, etc.).
(3) Kuchuluka kwa mpweya wa okosijeni, phokoso lochepa, palibe kuipitsidwa kwachiwiri, kuyaka pang'onopang'ono, kutsika mtengo, komanso kuyendetsa bwino ntchito.
3 Technology Ntchito
Kapangidwe ka petrochemical, utoto, electroplating, kusindikiza, zokutira, kupanga matayala ndi mafakitale ena onse amaphatikiza kugwiritsa ntchito ndi kutulutsa kwamafuta osakhazikika. The zoipa kosakhazikika organic mankhwala nthawi zambiri hydrocarbon mankhwala, mpweya munali organic mankhwala, chlorine, sulfure, phosphorous ndi halogen organic mankhwala. Ngati zinthu zosakhazikikazi zitayidwa mumlengalenga popanda chithandizo, zitha kuwononga chilengedwe. Njira zachikhalidwe zoyeretsera zinyalala za gasi (monga adsorption, condensation, kuyaka mwachindunji, etc.) zili ndi zolakwika, monga zosavuta kuyambitsa kuipitsa kwachiwiri. Pofuna kuthana ndi vuto la njira zochizira zinyalala zamagasi, njira yoyatsira moto imagwiritsidwa ntchito kuyeretsa zinyalala za gasi.
Catalytic kuyaka njira ndi zothandiza ndi yosavuta organic zinyalala kuyeretsedwa luso luso, luso ndi makutidwe ndi okosijeni kwambiri mamolekyu organic pamwamba pa chothandizira kukhala wopanda vuto carbon dioxide ndi madzi njira, amatchedwanso catalytic wathunthu makutidwe ndi okosijeni kapena chothandizira kwambiri makutidwe ndi okosijeni njira. kupangidwa kumagwirizana ndi ukadaulo woyatsira moto wamagasi otayika a benzene, omwe amagwiritsa ntchito chothandizira zitsulo zotsika mtengo, zomwe zimapangidwa ndi CuO, MnO2, Cu-manganese spinel, ZrO2, CeO2, zirconium ndi cerium solid solution, Zingathe kuchepetsa kwambiri kutentha kwa kutentha kwa catalytic, kupititsa patsogolo ntchito zothandizira, komanso kukulitsa moyo wa catalyst.Zopangidwazo zimagwirizana ndi chothandizira kuyaka, chomwe ndi chothandizira kuyaka kwa kuyeretsedwa kwa gasi wonyansa, ndipo kumakhala a blocky zisa ceramic chonyamulira mafupa, ❖ kuyanika pa izo ndi wolemekezeka zitsulo yogwira component.The ❖ kuyanika chothandizira wapangidwa ndi gulu okusayidi wopangidwa ndi Al2O3, SiO2 ndi chimodzi kapena zingapo zamchere dziko zitsulo oxides, kotero ali wabwino kutentha. kukaniza. Zomwe zimagwiritsidwa ntchito pazitsulo zamtengo wapatali zimanyamulidwa ndi njira ya impregnation, ndipo kugwiritsa ntchito bwino kumakhala kwakukulu.
