LEDS tuaj online
UV-C LED systems tau yog ib feem ntawm ntau qhov kev tshawb fawb, suav nrog kev tshawb fawb hauv tsev kawm qib siab, National Science Foundation (NSF) cov nyiaj pab thiab tsis ntev los no Daim Ntawv Pom Zoo Kev Tshawb Fawb thiab Kev Txhim Kho (CRADA) ntawm US EPA, Washington University thiab ib qho tseem ceeb UV manufacturers. Cov ntaub ntawv tshawb fawb no, yos rov qab mus rau xyoo 2012, muab qhov kev ntseeg siab thiab kev ua neej ntev uas feem ntau xav tau hauv qee yam tseem ceeb xws li kev kho dej haus. Lub hom phiaj tseem ceeb ntawm Teb Chaws Asmeskas EPA CRADA daim ntawv cog lus yog txhawm rau kuaj thiab siv tau cov kab dej kho dej nrog UV-C LED tshuaj tua kab mob thev naus laus zis. Cov cuab yeej tsom mus rau cov dej ntws ntau dua thiab cov dej sib tw ntau dua li hais nrog tam sim no muaj UV-C LED kev lag luam. CRADA tau qhia txog kev ua tau zoo ntawm lub ntiaj teb thawj zaug kev lag luam muaj UV-C LED POE kev kho mob.
Kev loj hlob ntawm UV LED systems hauv khw
Qhov kev xav tau ntau ntxiv thiab xav tau kev daws teeb meem rau kev noj qab haus huv thiab kev ua neej zoo ntawm cov teeb meem yuav tsum tau lees paub qhov chaw tseem ceeb ntxiv rau UV-C LED thev naus laus zis hauv thaj tsam ntawm cov txheej txheem kho dej zoo dua. Kev txhim kho txuas ntxiv ntawm kev ua tau zoo thiab txo tus nqi yog twb tso cai rau qhov no tshwm sim thiab tsuas yog nce kev nkag mus rau kev lag luam yav tom ntej.
Thaum cov pa mercury - teeb-raws li UV tshuaj tua kab mob yuav txuas ntxiv ua tus thawj coj ntawm qee qhov kev lag luam, tshwj xeeb tshaj yog siab - khiav lag luam thiab kev lag luam, muaj ntau yam ntxiv (xws li tus nqi ntawm kev ua tswv cuab thiab ntev- cov kev xav tau ntawm kev saib xyuas lub sijhawm) uas yuav ua rau kev siv UV-C LED li hauv ntau daim ntawv thov. Vim yog cov khoom tshwj xeeb ntawm uv-c coj, fouling yog qhov tsis tshua muaj kev txhawj xeeb vim tias cov pa tawm cua sov tau tswj xyuas tom qab ntawm lub tshuab siv lub tshuab cua sov es tsis yog lub quartz teeb / lub tes tsho / dej cuam tshuam, qhov twg fouling thiab qhov txo qis UV kis tau tuaj yeem tshwm sim hauv cov dej uas muaj cov ntxhia hardness. Hauv cov txheej txheem ib txwm siv, tam sim - ntawm LED thev naus laus zis tso cai rau lub zog ntawm LEDs tsuas yog thaum dej ntws, yog li tshem tawm cov cua sov tsim- uas ua rau fouling thaum tsis muaj zog (tsis muaj dej ntws) feem ntau pom hauv cov tshuab siv cov roj teeb uas muaj mercury mus tas li. Kev tshem tawm cov dej kub uas paub txog kev txhaj tshuaj cuam tshuam nrog cov kab ke ib txwm tsis tau nruab nrog kev tswj hwm qhov kub thiab txias yog qhov txiaj ntsig ntxiv. Cov khoom tam sim ntawm / tawm ntawm LEDs thiab qhov muaj peev xwm ua tau rau lub zog tsuas yog thaum xav tau kom txo tau lub teeb hloov lub sijhawm thaum piv nrog cov teeb pom kev zoo mercury. Raws li kev xav tau dej hauv tsev nruab nrab ntawm 2-3 teev hauv ib hnub, lub sijhawm hloov pauv rau LEDs feem ntau yog tsib xyoos, piv rau txhua xyoo hloov cov teeb mercury. Qhov kev thov kom tau txais txiaj ntsig zoo, ua ke nrog kev tswj hwm lub zog xav tau, txhais tau hais tias qhov ntev - lub sij hawm hluav taws xob xav tau yog qhov qis dua rau UV-C LED systems.
