Ammonia (NH3), ib qho inorganic compound, tsis muaj xim thiab muaj ntxhiab tsw. Nws yog yooj yim soluble nyob rau hauv dej. Ammonium ntsev tuaj yeem tau txais los ntawm kev ua ntawm ammonia thiab acid. Ammonia feem ntau yog siv los ua cov tub yees thiab npaj ammonium ntsev, nitrogen chiv, chiv chiv, nitric acid, ammonium ntsev, dej qab zib tshauv, thiab lwm yam. Cov additives muaj ib tug loj npaum li cas ntawm ammonia tshuaj. Los ntawm kev siv tes tuav ammonia tswb, nws paub tias nws txo qis rau ammonia thiab tso rau hauv phab ntsa nrog kev hloov ntawm qhov kub thiab txias, av noo thiab lwm yam ib puag ncig.
Poisoning manifestations:rhinitis, pharyngitis, mob caj pas, hoarseness, khaus qhov muag, qhov muag qhuav, txham, caj pas qhuav, los ntswg qhov ntswg, uas yuav ua rau convulsions, convulsions, tsaug zog, coma thiab lwm yam tsis meej pem. Nws tuaj yeem hlawv daim tawv nqaij, qhov muag thiab cov mucous ntawm cov kab mob ua pa. Yog tias tib neeg nqus tau ntau dhau, nws tuaj yeem ua rau lub ntsws o. Cov neeg mob nqus tau ammonia muaj zog heev, uas tuaj yeem ua rau ua pa thiab mob plawv thiab tuag taus.
1.Kev ntsuas los tiv thaiv ammonia lom:
1. Nruab thiab sivammonia gas ntesthiab roj ammonia leakage saib ntawm qhov chaw, thiab lub tswb raws sij hawm seb nws mus txog qhov tsis zoo;
2. Cov khaub ncaws ua haujlwm tiv thaiv corrosion, hnab looj tes tiv thaiv alkali, tsom iav, khau roj hmab thiab lub npog ntsej muag roj yuav tsum raug xaiv thaum ua haujlwm, thiab lub npog ntsej muag roj yuav tsum tau kuaj xyuas tsis tu ncua;
3. Thaum siv dej ammonia rau kev ua haujlwm, khaws cov dej huv nrog koj nyob rau hauv rooj plaub; Thaum lub sij hawm kev thauj mus los ntawm ammonia, 3 feem pua ntawm cov tshuaj boric acid yuav tsum tau khaws cia nrog koj rau kev tshem tawm thaum muaj xwm txheej ceev; Hnav looj tsom iav thaum npaj ammonia nrog ib qho concentration; Thaum siv ammonia, tus neeg teb xov tooj yuav tsum tau upwind los tiv thaiv ammonia los ntawm kev khaus ntawm lub ntsej muag; Nws yog txwv tsis pub rub koj ob lub qhov muag nrog koj txhais tes thaum ua haujlwm, thiab ntxuav koj txhais tes tom qab ua haujlwm;
4. Muab qhov cua zoo thiab tso pa tawm thiab cov khoom siv hluav taws xob tawg thiab hluav taws kub;
5. Kev noj haus, haus luam yeeb, qhib hluav taws thiab taws tswm ciab hauv chaw ua haujlwm;
6. Hnav lub tshuab ua pa thaum muaj xwm txheej ceev;
2, Kev teeb tsa thiab kev xav tau ntawm ammonia tswb
Qhov ceev ntawm ammonia gas yog tsawg dua li ntawm huab cua. Lub detector yuav tsum tau nruab 0.5m-2m saum toj no qhov to, thiab qhov sensor yuav tsum downward.
2. Tsis txhob nruab lub cuab yeej hauv cov haujlwm hauv qab no:
① Qhov chaw ncaj qha cuam tshuam los ntawm chav thiab roj fume;
② Huab cua chaw nres nkoj, cua ntxuam, qhov rooj thiab lwm qhov chaw uas muaj huab cua loj;
③ Qhov twg muaj ntau cov dej vapor thiab cov tee dej (cov av noo: Ntau dua lossis sib npaug li 90 feem pua);
④ Qhov ntsuas kub qis dua - 30 degree lossis siab dua 50 degree ;
⑤ Cov chaw muaj zog electromagnetic;
