Dab tsi yog hom sensors rau nitrogen oxide detectors?
Nitrogen oxides, feem ntau yog nitric oxide thiab nitrogen dioxide, yog vim li cas tseem ceeb rau kev tsim ntawm photochemical smog thiab acid nag. Cov pa luam yeeb tsim los ntawm cov tshuaj tiv thaiv ntawm nitrogen oxides hauv lub tsheb tso tsheb thiab hluav taws xob ultraviolet hu ua photochemical pa luam yeeb.
Cov pa luam yeeb photochemical muaj cov ntxhiab tsw tshwj xeeb uas txhawb lub qhov muag, ua rau cov nroj tsuag, thiab tuaj yeem txo qhov pom ntawm huab cua. Nws yog cov pa phem rau tib neeg lub cev thiab cov nroj tsuag. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum siv lub tshuab ntsuas nitrogen oxide kom zoo saib xyuas cov emission ntawm nitrogen oxides, yog li txo qhov tshwm sim ntawm cov xwm txheej.
Qhov tseem ceeb ntawm lub tshuab hluav taws xob nitrogen oxide yog lub ntsuas roj. Cov roj sensors ntawm nitrogen oxide detectors tuaj yeem muab faib ua peb pawg hauv txoj cai:
Gas sensors siv lub cev thiab tshuaj lom neeg, xws li hom semiconductor (sov tswj, ntim tswj, hom muaj peev xwm nto), hom catalytic combustion, khoom thermal conductivity hom, thiab lwm yam.
Gas sensors siv lub cev muaj zog, xws li thermal conductivity, optical cuam tshuam, infrared absorption, thiab lwm yam.
Gas sensors siv cov khoom siv hluav taws xob, xws li qhov muaj peev xwm electrolysis, Gavanni roj teeb, membrane ion electrode, tsau electrolyte, thiab lwm yam.
Ntau thiab ntau qhov xwm txheej dej paug ua rau neeg lub siab. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum siv lub tshuab ntsuas nitrogen oxide kom zoo saib xyuas cov pa nitrogen oxide emissions, txo kev puas tsuaj rau tib neeg lub cev, thiab yog li txo cov xwm txheej.
