Kodi ULTRAVIOLET Photocatalysis ndi chiyani?

Ndi kupita patsogolo kwa sayansi ndi zamakono, kukwera kwachuma, ndi lingaliro la anthu la thanzi ndi chitetezo cha chilengedwe, anthu ndi mabanja ambiri amayamba kumvetsera khalidwe la mpweya wamkati ndikuzindikira kufunika koyeretsa mpweya. Pakalipano, njira zomwe zimagwiritsidwa ntchito poyeretsa thupi la mpweya ndizo: 1. Adsorption fyuluta - activated carbon, 2. Mechanical fyuluta - HEPA net, electrostatic purification, photocatalytic njira ndi zina zotero.

Photocatalysis, yomwe imadziwikanso kuti UV photocatalysis kapena UV photolysis. Mfundo yake yogwirira ntchito: Mpweya ukadutsa mu chipangizo choyeretsera mpweya wa photocatalytic, photocatalyst palokha sisintha ndi kuwala kwa kuwala, koma imatha kulimbikitsa kuwonongeka kwa zinthu zovulaza monga formaldehyde ndi benzene mumlengalenga pogwiritsa ntchito photocatalysis, zomwe zimapanga zopanda mphamvu. -poizoni ndi zinthu zopanda vuto. Mabakiteriya omwe ali mumlengalenga amachotsedwanso ndi kuwala kwa ultraviolet, motero amayeretsa mpweya.

Mafunde a UV omwe amatha kujambulidwa ndi UV photocatalysis nthawi zambiri amakhala 253.7nm ndi 185nm, ndipo ndikukula mwachangu komanso kupita patsogolo kwaukadaulo, pali 222nm yowonjezera. Mafunde awiri oyambilira ali pafupi kwambiri ndi 265nm (omwe pakali pano ndi kutalika kwake komwe kuli ndi mphamvu yamphamvu kwambiri ya bactericidal pa tizilombo tating'onoting'ono tomwe tapezeka muzoyeserera zasayansi), kotero kuti bactericidal disinfection ndi kuyeretsa kwake ndikwabwinoko. Komabe, chifukwa chakuti kuwala kwa ultraviolet mu gululi sikungathe kuyatsa khungu la munthu kapena maso mwachindunji, chida cha 222nm ultraviolet choyeretsa chapangidwa kuti chithetse vutoli. Kutsekereza, kupha tizilombo toyambitsa matenda ndi kuyeretsa kwa 222nm ndikotsika pang'ono poyerekeza ndi 253.7nm ndi 185nm, koma kumatha kuyatsa khungu kapena maso amunthu mwachindunji.

Pakalipano, amagwiritsidwa ntchito kwambiri m'mafakitale, monga mankhwala opangira gasi wotayira fakitale, kuyeretsa fume yamafuta akukhitchini, malo ochitira masewera olimbitsa thupi, mafakitale ena opaka utoto ndi mankhwala ena onunkhira a gasi, kuyeretsa m'mafakitale a zakudya ndi mankhwala, ndi kuchiritsa utsi. Nyali za ultraviolet zokhala ndi mafunde a 253.7nm ndi 185nm zimagwiritsidwa ntchito kwambiri. Pogwiritsa ntchito kunyumba, zoyeretsa mpweya wa ultraviolet zokhala ndi kutalika kwa 253.7nm ndi 185nm, kapena nyali za desk za ultraviolet zitha kusankhidwa kuti zikwaniritse kuyeretsa mpweya wamkati, kutsekereza, kuchotsa formaldehyde, nthata, kuchotsa bowa, ndi ntchito zina. Ngati mukufuna kuti anthu ndi magetsi azikhala m'chipindamo nthawi yomweyo, mutha kusankha nyali ya desiki ya 222nm ultraviolet sterilization desk. Mpweya uliwonse womwe iwe ndi ine timapuma ukhale wapamwamba kwambiri! Mabakiteriya ndi ma virus, chokani! Muli kuwala mu moyo wathanzi
