Cov ntawv thov ntawm cov ntsuas roj tsau hauv kev lag luam thiab lwm yam kev lag luam
Vim tias cov tshuaj lom neeg muaj feem cuam tshuam nrog hauv cov khoom lag luam, txawv BW Taag soj ntsuam muaj peev xwm tau nruab nrog cov tshuaj lom neeg tshwj xeeb uas lub Hoobkas raug rau.
Petrochemical Kev Lag Luam
Ntau tshaj 80% ntawm thaj chaw ntau lawm hauv kev lag luam petrochemical muaj lub peev xwm rau cov nplaim taws thiab kev tawg. Raws li "tsim cov roj txheem rau cov roj sib txuas thiab tshuaj lom kom zoo nkauj ntawm cov roj txheem hluav taws xob", cov khoom lag luam zoo ntawm cov roj kab rov tav yog 7.5 metres sab hauv tsev thiab 15 meters sab nraud. Tsawg kawg ib ntes ntes yuav tsum tau nruab rau hauv thaj chaw zoo. Ib qho ntxiv, cov neeg kuaj yuav tsum tau muab ntsia nyob ze ntawm cov inlet thiab outlet valve cov chav tso, thiab chav tsev compressor, thiab chav ntim chav nyob uas yuav muaj roj av.
Feem ntau, nws yog qhov tsim nyog yuav tsum tau siv BW LEL lossis IR los soj ntsuam rau cov dej ntws tawm. Bw lel lossis ir implists qib thib ob tswb. Thaum cov roj concentration ntawm cov roj txuas tau mus txog 10% Lel (qis qis (20% Lel, tus soj xyuas yuav muab qhov kev pom thib ob. Lub tswb ceeb toom kuj tseem tuaj yeem hloov kho raws li cov neeg siv yuav tsum tau.
Rau cov tshuaj lom thiab muaj teeb meem volatic meround zoo xws li Benzene, Aniline Distride, thiab lwm yam. Rau kev kuaj pom ntawm Benzene Leaks hauv petrochemical nroj tsuag styrene chav nyob, bw pid tuaj yeem siv tau. BP Texas refinery, nyob hauv Texas, USA, siv ib lub teeb bw nrog ib qho 9.8 Ev Ultraviolet teeb kom saib xyuas thiab ceeb toom rau Benzene Leaks hauv kev ua haujlwm ntau lawm. Thaum ntau dua ib nrab xyoo ntawm kev saib xyuas tas mus li, bw pid kom yog thiab muaj txiaj ntsig zoo lub tswb rau benzene to kev sib tsoo uas tau tshwm sim thaum lub sijhawm no.
Metallurgical Kev Lag Luam
Kev lag luam metallurgical, tshwj xeeb tshaj yog cov hlau smelting, siv roj siv roj li roj. Vim yog cov ntsiab lus siab ntawm co nyob rau hauv lub zog hluav taws xob roj teeb, thiab cokke cub roj, thiab co tawg kev sib tw yog vim qhov tsis muaj kev nrawm nrawm rau co thiab compustible gases. Kev tiv thaiv kev sim cov khoom lag luam hlau feem ntau yog ad saws bw co to toxicity thiab bw lel rau kev saib xyuas tag nrho cov gases. Saib xyuas cov concentration ntawm cov pa roj lom thiab cov roj ntsha tuaj yeem taug qab hloov roj hauv ib puag ncig. Yog tias cov roj nce mus txog qee qhov kev xav tau, qhov ntsuas tau tuaj yeem muab lub cim qhia tswb rau ceeb toom ceeb toom cov neeg ua haujlwm nyob ze. Kev ntsuas kev khiav tawm tam sim ntawd thiab kev ntsuas thaum muaj xwm ceev kom tsis txhob muaj kev txhim kho ntxiv cov xwm txheej thiab raug xwm txheej lossis tawg.
