Smoldering hluav taws feem ntau zais thiab yooj yim overlooked tab sis dheev tuaj yeem nce mus rau hauv cov nplaim taws sai sai.
2. Cov pa luam yeeb dub: Cov yam ntxwv thiab qhov chaw
Yam ntxwv:
Xim:Pom muaj xim dub lossis grey tsaus.
Particle Loj:Cov khoom me me (<1 micron), denser, thiab muaj zog lub teeb haum.
Kub:Cov pa luam yeeb dub feem ntau cuam tshuam nrog kub kub combustion thiab kub ceev.
Kev sib xyaw:
Cov pa roj carbon monoxide (cov khoom siv hluav taws kub tsis tiav).
Tar thiab lwm yam complex organic tebchaw.
Qhov chaw:
Cov pa luam yeeb dub feem ntau yog tsim los ntawmhluav taws kub, uas yog tus yam ntxwv los ntawm qhov kub thiab txias combustion, feem ntau pom nyob rau hauv:
Synthetic khoom hluav taws kub:Hlawv cov yas, roj hmab, roj, thiab tshuaj lom neeg.
Roj hluav taws kub: combustion ntawm roj av, diesel, thiab cov khoom zoo sib xws ua rau cov pa roj carbon ntau.
Tom qab theem ntawm hluav taws, qhov twg combustion intensifies, tso tawm ntau zoo hais thiab cov pa taws kub.
Kev phom sij:
Cov pa luam yeeb dub feem ntau qhia tau hais tias hluav taws kub ceev, kub siab, thiab muaj peev xwm tawg tau.
Nws muaj cov pa phem ntau heev xws licarbon monoxide (CO)thiabHydrogen Cyanide (HCN), ua rau muaj kev phom sij tseem ceeb rau kev noj qab haus huv.
3. Kev sib piv ntawm cov pa luam yeeb dawb thiab cov pa luam yeeb dub
| Yam ntxwv | Haus luam yeeb dawb | Haus luam yeeb dub |
|---|---|---|
| Xim | Dawb los yog lub teeb grey | Dub los yog tsaus grey |
| Particle Loj | Cov khoom loj dua (> 1 micron) | Cov khoom me me (<1 micron) |
| Qhov chaw | Smoldering hluav taws, qis-kub combustion | Nplaim hluav taws kub, kub ceev combustion |
| Cov Khoom Siv | Ntoo, paj rwb, ntawv, thiab lwm yam khoom siv ntuj tsim | Plastics, roj hmab, roj, thiab cov khoom siv tshuaj |
| Kev sib xyaw | Cov dej vapor thiab lub teeb yuag | Carbon particles, tar, thiab organic compounds |
| Kev phom sij | Muaj peev xwm txaus ntshai, tuaj yeem tso cov pa phem | Cov hluav taws kub kub, kis tau sai, muaj cov pa phem |
4. Lub tswb hluav taws xob pom cov pa luam yeeb dawb thiab dub li cas?
Txhawm rau kom pom cov pa luam yeeb dawb thiab dub zoo, cov pa taws niaj hnub no siv cov thev naus laus zis hauv qab no:
1. Photoelectric Detectors:
Ua haujlwm raws li lub hauv paus ntsiab lus ntawmlub teeb tawgtxhawm rau txheeb xyuas cov khoom loj hauv cov pa luam yeeb dawb.
Qhov zoo tshaj plaws rau kev tshawb pom ntxov ntawm cov hluav taws kub hnyiab.
2. Ionization Detectors:
Ntau dua rau cov me me hauv cov pa luam yeeb dub.
Ceev nrooj ntes hluav taws kub kub.
3. Dual-Sensor Technology:
Muab cov thev naus laus zis thev naus laus zis thiab ionization txhawm rau kuaj pom cov pa luam yeeb dawb thiab dub, txhim kho qhov tseeb ntawm hluav taws.
4. Multi-Function Detectors:
Muab cov ntsuas kub ntsuas, cov pa roj carbon monoxide (CO) ntes, lossis ntau lub tshuab hluav taws xob kom zoo dua qhov sib txawv ntawm hluav taws thiab txo cov tswb cuav.
5. Cov lus xaus
Cov pa luam yeeb dawbFeem ntau yog tshwm sim los ntawm cov hluav taws kub hnyiab, uas yog cov khoom loj dua, qhov kub thiab txias, thiab qhov tseem ceeb ntawm cov dej vapor thiab cov pa phem.
Cov pa luam yeeb dubFeem ntau yog cuam tshuam nrog hluav taws kub siab-flaming hluav taws, muaj cov lus me me, denser hais thiab tua hluav taws nrawm.
Niaj hnubdual-sensor pa luam yeeb ntesyog qhov zoo los kuaj xyuas cov pa luam yeeb dawb thiab dub, txhim kho kev ceeb toom hluav taws kom raug thiab kev ntseeg tau.
Kev nkag siab txog cov yam ntxwv ntawm cov pa luam yeeb tsis tsuas yog pab xaiv lub tswb hluav taws xob kom raug, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws thiab teb kom txo qis kev pheej hmoo zoo.
