1. Vim li cas hydrogen sulfide tsim?
Hydrogen sulfide yog xim tsis muaj xim, muaj kuab lom heev nrog cov ntxhiab tsw ntawm cov qe lwj. Kev nqus tau cov roj ntau ntau yuav ua rau olfactory qaug zog sai thiab tsis pom nws tsis hnov tsw. Thaum lub concentration ntawm hydrogen sulfide nyob rau hauv cov huab cua mus txog 0.025-0.1, koj muaj peev xwm tsw. Thaum cov concentration nce mus txog 10-15ppm, yuav muaj qhov tshwm sim me me lom; Thaum cov concentration nce mus txog ntau tshaj 200ppm, muaj peev xwm ua rau tuag taus.
Nws tsis yog qhov tsis yooj yim rau hydrogen sulfide tshwm sim hauv cov tuam txhab khoom noj, vim tias qee cov zaub mov yuav tsum tau fermented. Piv txwv li: lub tuam txhab koom nrog hauv kev tsim thiab ua zaub mov, tsim Luo Han xyoob tua, thiab Luo Han xyoob ntoo yuav tsum tau fermented, thiab cov khoom xws li hydrogen sulfide yuav tsim thaum lub sij hawm fermentation txheej txheem. tuaj yeem tsim hydrogen sulfide hauv cov txheej txheem ntawm fermenting organic teeb meem. Tau kawg, ntxiv rau hydrogen sulfide, muaj ntau lwm yam tshuaj, uas yog vim li cas cov chaw no tsw phem heev.
2.Yuav ua li cas tiv thaiv hydrogen sulfide lom
(1). Cov khoom siv ntau lawm uas tsim cov tshuaj hydrogen sulfide yuav tsum raug kaw raws li qhov ua tau thiab nruab nrog lub tswb tsis siv neeg (qhov concentration ntawm hydrogen sulfide nyob rau hauv qhov chaw txaus ntshai tsis tuaj yeem txiav txim siab raws li qhov tsis hnov tsw. Thaum hydrogen sulfide nce mus txog ib qho concentration, nws yuav ua rau olfactory tuag tes tuag taw).
(2). Cov dej khib nyiab, cov pa khib nyiab, thiab cov khoom pov tseg uas muaj hydrogen sulfide yuav tsum tau ua kom huv thiab tso tawm tsuas yog tom qab ua tau raws li cov qauv emission.
(3). Thaum nkag mus rau hauv cov thawv kaw, lub qhov cub, qhov cub, trenches thiab lwm qhov chaw ua haujlwm uas muaj hydrogen sulfide, qhov concentration ntawm hydrogen sulfide nyob rau hauv qhov chaw yuav tsum tau ntsuas ua ntej, qhov cua thiab detoxification ntsuas yuav tsum tau ua, thiab kev ua haujlwm tuaj yeem ua tiav tsuas yog tom qab kev nyab xeeb tau lees paub. Qhov concentration ntawm hydrogen sulfide yuav tsum ntsuas tsis tu ncua thaum lub sijhawm ua haujlwm.
(4). Siv cov kev tiv thaiv tus kheej thaum lub sijhawm ua haujlwm, nruab nrog cov khoom siv los tiv thaiv - roj (ntau lub npog ntsej muag feem ntau yog siv rau kev khiav tawm thiab tus kheej- cawm), thiab khi txoj hlua cawm los yog hlua ib ncig ntawm lub duav ntawm tus neeg teb xov tooj. Kev tiv thaiv kev sib nrig yuav tsum ua kom zoo, thiab ntau tshaj 2 tus neeg yuav tsum tuaj.
(5). Cov neeg uas muaj kab mob siab, kab mob raum, thiab tracheitis tsis raug tso cai ua haujlwm nrog kev sib cuag nrog hydrogen sulfide.
(6). Txhim kho kev cob qhia cov neeg ua haujlwm txog kev paub txog kev nyab xeeb thiab kev txawj ntse los txhim kho tus kheej - kev paub txog kev tiv thaiv thiab kev muaj peev xwm.
Muaj hydrogen sulfide roj tswb tswb ntes tau zoo ntes cov concentration ntawm hydrogen sulfide roj thiab tiv thaiv cov concentration ntawm cov pa phem tshaj tus qauv tom qab roj to. Lub tshuab hluav taws xob hydrogen sulfide muaj ob ntu: lub tswb ntsuas hluav taws xob thiab H2S roj ntes. Lub tshuab hluav taws xob hydrogen sulfide tuaj yeem muab tso rau hauv chav ua haujlwm. Lub tshuab hluav taws xob hydrogen sulfide tau nruab rau ntawm qhov chaw uas cov roj feem ntau yuav xau. Cov ntsiab lus tseem ceeb ntawm lub tshuab ntsuas roj yog qhov ua tau -hauv roj sensor. Lub cev hydrogen sulfide sensor pom qhov concentration ntawm hydrogen sulfide gas nyob rau hauv cov huab cua. Lub tshuab ntsuas roj hloov pauv cov roj hydrogen sulfide cov roj concentration kuaj pom los ntawm h2s sensor rau hauv lub teeb liab hluav taws xob thiab xa mus rau tus maub los ntawm lub cable. Qhov siab dua qhov hydrogen sulfide gas concentration, lub zog hluav taws xob teeb liab. Thaum cov roj concentration nce mus txog lossis tshaj lub tswb ceeb toom los ntawm lub tswb hluav taws xob, lub tswb hluav taws xob xa hluav taws xob xa hluav taws xob.
