Lub hauv paus ntsiab lus ntawm Ultraviolet Teeb
Sep 12, 2021
1. Ultraviolet lub teeb yog tsim nyob rau hauv ib tug mercury paug raj. Cov roj inert ntawm mercury vapor yog raug tshem tawm hauv lub raj. Nws yog quartz iav raj uas muaj ob lub electrodes thiab insulator.
Thaum lub teeb ultraviolet muaj zog thiab zoo siab, cov mercury nce mus txog qhov siab tshaj plaws ntawm 254nm, 310nm thiab 365nm, tsim hluav taws xob ultraviolet ntawm 200 thiab 400nm. Ntawm lawv, 365nm hom ultraviolet teeb yog dav siv nyob rau hauv kev lag luam nto. Kev ziab thiab kho ntawm kev ua haujlwm; 254nm thiab tshwj xeeb 185nm teeb yog feem ntau siv rau kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob, kev kho dej phwj tuaj, roj fume purification, thiab txawm tias lub teeb tu.
Feem ntau siv ultraviolet teeb yog tsim los ntawm kev siv lub zog dielectric mercury arc teeb lossis MPMA teeb. Nws tuaj yeem tsim tau rau hauv qhov ntev ntawm ob peb millimeters mus rau ntau tshaj 2 meters, thiab lub zog muaj peev xwm tsawg dua 1W hauv cov teeb pom kev zoo, thiab lub teeb kho tuaj yeem ncav cuag 25KW. Lub neej ntawm cov teeb kho no txawv ntawm 1,000 txog 2,500 teev, thiab lub neej ntawm cov teeb pom kev zoo sib txawv ntawm 6,000 txog 20,000 teev.
2. Lub raj roj teeb ultraviolet yog ua los ntawm quartz iav raj, vim nws tsuas yog cov khoom siv uas xa cov teeb ci ultraviolet thiab tuaj yeem tiv taus qhov kub ntawm 6 txog 800 ° C. UV raj yuav nthuav me ntsis thiab muaj qhov kub ntawm qhov kub (1100 ° C).
3. Electrodes yog ua los ntawm tungsten: Cov txheej txheem ntawm kev tsim lawv yog qhov nyuaj heev. Tungsten yog siv vim qhov kub ntawm qhov nkhaus tuaj yeem nce mus rau ntau tshaj 3000 ° C.
4. Siv molybdenum phaj los txuas electrodes thiab xov hlau, uas tuaj yeem nthuav ua ke nrog quartz. Thiab nws tseem tuaj yeem zam qhov siab voltage thaum rhuab.
5. Lub teeb thaum kawg raug tshem tawm mus rau ib qho ceramic (los yog lwm yam) insulator.
6. Vim hais tias cov khoom siv tam sim no feem ntau tsis txaus rau lub hwj chim MPMA teeb, UV teeb feem ntau sib phim nrog lub tshuab hluav taws xob thiab lub capacitor.
