Kev sib piv technology
Mercury vapor teeb nyob rau hauv ntau yam iterations (nruab nrab- thiab qis-siab) tau nyob rau hauv lub hauv paus ntawm UV tshuaj tua kab mob rau ntau xyoo lawm. Txawm hais tias kev siv cov LEDs hauv kev lag luam pom teeb pom kev zoo tau dhau los ua ib qho chaw nyob rau xyoo kaum xyoo dhau los, lawv siv nyob rau hauv cov chaw tua kab mob tau pib txwv rau cov ntawv tshwj xeeb tshwj xeeb vim yog tus nqi siab thiab txwv UV tso zis efficiency. Nyob rau hauv xyoo tas los no, kev ua haujlwm zoo tau ua tiav hauv kev ua kom zoo UV-C LED thev naus laus zis mus rau qhov chaw uas tus nqi- kev tsom xam tau txais txiaj ntsig tau zoo dua, thawj zaug hauv POU daim ntawv thov (xws li kev xa dej) thiab, tsis ntev los no, hauv POE daim ntawv thov. Cov kev tsis zoo thaum ntxov ntawm cov khoom toxicity, kev tswj kom sov, thiab tus nqi tau hais. Tag nrho cov ntaub ntawv siv tam sim no txo qis cov khoom phom sij (RoHS)- ua raws, cov khoom siv hluav taws xob sib xyaw ua ke tswj cov thermal tswj tau zoo thiab tsis tu ncua kev txhim kho tus nqi piv rau cov khoom tsim tawm tau zoo los ntawm cov duab sawv cev ntawm Haitz Txoj Cai (saib daim duab 1). Haitz txoj cai yog qhov pom thiab kwv yees kev txhim kho ntawm LEDs ntau xyoo. Txoj cai lij choj no tau pom tias txhua xyoo kaum xyoo, tus nqi poob los ntawm ib qho ntawm 10 thiab cov nyiaj tau los ntawm lub teeb tsim tau nce los ntawm ib qho ntawm 20. Qhov kev hloov pauv no tau tshwm sim nyob rau tib lub sijhawm uas lub siab kom tshem tawm kev siv thiab tom qab pov tseg ntawm mercury yog nce.
At their core, UV disinfection systems are based on two principles – the efficiency of the UV lamp and the efficiency of the reactor design. Typically, conventional UV lamps are more efficient, producing more UV light than heat when compared to UV-C LED light sources. The opposite is true with conventional mercury lamp reactor design, as the cylindrical design is typically less efficient than modern UV-C LED reactors, which can be custom-designed based on the flexibility of the LEDs. In addition to the cost versus output improvements noted above, UV-C LED reactor and UV output efficiency are both benefitting from continuous improvement at a rapid pace, accelerating the penetration of LED technology into higher-flow applications. A particular advantage offered by UV-C LED technology is the ability to tailor UV wavelengths for specific, targeted applications due to not being constrained by the 254nm output of low-pressure mercury vapor lamps.
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.
