Frozen food factories yeej koom nrog ammonia tub yees. Qhov twg muaj ammonia roj, muaj ib lub sij hawm foob pob faus. Txhawm rau kom tshem tawm cov teeb meem ntawm lub foob pob no, peb cov chaw tsim khoom noj khoom haus khov tau yuav thiab teeb tsa cov kua ammonia xau ceeb toom ntawm qhov kev thov ntawm Lub Xeev Kev Tswj Xyuas Kev Nyab Xeeb Kev Nyab Xeeb los tiv thaiv ammonia to. thaum muaj xwm txheej ceev xws li gas leaks. Txawm li cas los xij, ntau lub tuam txhab tseem tsis tau teb rau qhov yuav tsum tau ua ntawm lub chaw soj ntsuam kev ruaj ntseg, thiab tseem mus rau lawv tus kheej txoj kev, pib ntau lawm los ntawm hmoov zoo, tsis muaj kev ceev faj. Nws zoo nkaus li tias ammonia to explosion lom tshwm sim tseem tsis tau sounded lub tswb rau cov lag luam!
Lub tswb kua ammonia feem ntau yog muag hauv cov chaw ua haujlwm tub yees ntawm cov khoom noj khoom haus thiab cov nroj tsuag tshuaj. Vim tias cov roj ammonia ua rau khaus heev, tib neeg tuaj yeem raug tshuaj lom yog tias lawv nqus tau me me. Yog li ntawd, cov chaw uas muaj ammonia roj to yuav tsum ua raws li lub teb chaws txoj cai thiab yuav tsum tau tswj kom tsim nyog. Kev txhim kho kom zoo ntawm ammonia leakage tswb yog cuam tshuam rau kev nyab xeeb ntawm lub neej thiab khoom. Tau kawg, thaum kuaj pom lub tswb ammonia leakage, peb yuav tsum xaiv lub tswb nrov tshaj plaws ammonia.
Rau kev tshawb nrhiav cov kua ammonia to alarms nyob rau hauv kev lag luam, tus nqi sib txawv ntawm kev tshawb nrhiav cov ammonia combustible thiab nrhiav tau cov tshuaj lom ammonia loj heev. Qhov laj thawj yog dab tsi. Vim tias qhov sib txawv loj tshaj plaws ntawm kev kuaj xyuas cov kua ammonia xau lub tswb thiab kuaj cov kua ammonia xau tswb yog qhov sib txawv ntawm cov roj av sensor. Nyob rau hauv tib qhov chaw, nyob rau hauv cov ntaub ntawv ntawm cov pa tawm, lub electrochemical sensor los tiv thaiv lom yuav tsum tswb ua ntej, xav tias lub electrochemical sensor yog rhiab heev tshaj lub catalytic combustion sensor.
Ammonia, Ammonia, NH3, roj tsis muaj xim. Nws muaj zog pungent tsw. Ceev 0.7710. Tus txheeb ze ntom ntom yog 0.5971 (air=1.00). Yooj yim liquefied rau hauv cov kua tsis muaj xim. Nws tuaj yeem ua kua dej los ntawm kev kub siab ntawm chav tsev kub (qhov kub tseem ceeb 132.4 degree, siab tseem ceeb 11.2 MPa, lossis 112.2 cua). Kub taw tes -33.5 degree .
Yog hais tias cov pa roj ammonia raug ntsuas, nws siv lub catalytic combustion sensor nrog qhov ntau ntawm 0-100 feem pua LEL. Muaj ob lub teeb tsa siab thiab qis qis, ib qho rau qis 25 feem pua LEL thiab ib qho siab rau 50 feem pua LEL. Qhov no yog los ntsuas cov pa tawg. txwv tus nqi. Yog tias cov roj ammonia muaj tshuaj lom, nws siv lub tshuab hluav taws xob hluav taws xob nrog qhov ntsuas ntawm 0-100ppm. Nws kuj muaj ob lub teeb tsa siab thiab qis qis. Ib qho yog qis ntawm 25ppm thiab siab ntawm 50ppm. Qhov no yog los ntsuas cov pa paug tawm.
Txawm hais tias ob lub tswb siab thiab qis qis yog tib yam, tab sis hom sensor sib txawv, qhov sib txawv tuaj yeem loj. Yog tias ammonia gas leaks, thawj lub tswb yog qhov ntau ntawm 0-100ppm, vim tias qhov rhiab heev ntawm electrochemical sensor yog siab dua, thiab 0-100 feem pua lel yog qhov ntau. Qhov tsawg kawg nkaus tawg txwv tus nqi ntawm ammonia roj tau muab faib ua 100 qhov sib npaug, thiab tom qab ntawd ob lub tswb ntsuas siab thiab qis yog coj los kuaj pom, thiab cov tshuaj tiv thaiv kuj qeeb.
Thiab rau cov roj ammonia, muaj ob yam khoom: ib qho yog flammable, thiab lwm yam yog tshuaj lom. Kuv xav kom cov neeg siv siv cov kua ammonia to alarms yog tias lawv xav tau ammonia tswb. Raws li qee qhov kev cai ceeb toom kev nyab xeeb, tsuas yog kev kuaj pom cov pa ammonia muaj tshuaj lom nws tuaj yeem dhau mus, thiab ammonia gas detection toxicity yog siab dua qhov rhiab heev ntawm kev tshawb nrhiav flammability. Lub sensor rau kev tshawb pom cov kua ammonia xau tswb muaj ob lub hauv paus ntsiab lus: hom catalytic combustion thiab electrochemical hom. Nws raug kuaj pom los ntawm LEL. Kev kuaj xyuas cov kua ammonia xau tswb yog ua raws li lub hauv paus ntsiab lus ntawm kev tshawb nrhiav electrochemical. Nws raug kuaj pom hauv ppm, feem ntau yog txhawm rau txhawm rau txhawm rau txhawm rau tshuaj lom. Lub electrochemical sensor muaj ib qho electrolyte, cov tshuaj tiv thaiv yog heev rhiab heev, thiab qhov tseeb ntawm kev kuaj pom yog siab heev, uas yog ob peb zaug ntau rhiab tshaj li catalytic combustion sensor.
