Yam yooj yim ntawm cov tsheb tua hluav taws feem ntau yog siv rau kev tua hluav taws hauv nroog.Thaum ua ntawv thov, lawv yuav tsum tau muab tso rau hauv qhov chaw tua hluav taws lossis cov dej nqus dej rau kev tua hluav taws.Lawv tuaj yeem siv los ua ntauwd-tsawg cov khoom siv dej siv tsheb rau lwm lub tsheb tua hluav taws.
Khaws thiab tshem tawm cov peev txheej dej kom sai sai tua hluav taws - dej cia tank hluav taws tsheb
Nws yog ib lub tsheb tua hluav taws tseem ceeb rau lub chaw tua hluav taws thiab tom qab hluav taws tua hluav taws ntawm cov pej xeem kev ruaj ntseg hauv nruab nrog cev.Vim tias lub tsheb tau nruab nrog cov khoom siv dej sib cais, nws tuaj yeem ua haujlwm yooj yim thiab cais cov haujlwm tua hluav taws txhua hnub hauv thaj chaw uas muaj dej me me, thiab nws tuaj yeem siv los ua cov khoom siv dej tsis pub ntauwd thiab cov khoom siv thauj mus los ntawm qhov chaw tua hluav taws.Txoj kev mus rau dej.
2. Kev cawm sai ntawm qhov chaw hluav taws kub tshwj xeeb
Flammable kua sai tua hluav taws - ua npuas ncauj yas hluav taws tsheb
Foam yas hluav taws tsheb yog lub tsheb tua hluav taws tsim nyog rau cov kws tshaj lij hluav taws xob hauv nroog loj.Nws yog tsim rau extinguishing flammable thiab flammable kua hluav taws kub xwm txheej.Nws yog heev haum rau extinguishing crude roj hluav taws kub xwm txheej.Nws yog siv nyob rau hauv cov tuam txhab petrochemical khoom, roj pipeline chaw nres nkoj, thiab tshav dav hlau.Yuav tsum muaj tsheb tua hluav taws.
Nws ua tiav cov nyhuv tua hluav taws raws li kev ua haujlwm zoo tshaj plaws ntawm cov yas ua npuas ncauj.(foased plastics muaj tsawg fluens, zoo rauv taws, muaj zog tawg, thiab cov cua sov siab sai sai, thiab cov khoom siv hluav taws kub kom sai sai roj thiab calorific nqi kom ua tiav lub hom phiaj ntawm kev tua hluav taws)
Cov kua dej tsis muaj dej sai sai tua hluav taws - kev nthuav dav ua npuas dej ntau
Nrog rau txoj kev loj hlob sai ntawm kev lag luam, kev siv hluav taws xob hluav taws xob kuj tau hloov kho dua tshiab.High-rate foam firefighting yog hom tshiab ntawm kev ua haujlwm siab thiab siv hluav taws xob tsawg.Tus nqi siab ua npuas ncauj yog ib yam khoom siv hluav taws xob ua npuas ncauj, uas tau txhim kho kev sib ntaus sib tua zoo heev piv rau qis thiab nruab nrab tus nqi ua npuas ncauj.Nws siv ntau npaum li cas ntawm polyurethane ua npuas ncauj, zoo heev tiv taus hluav taws, qis ntom thiab muaj zog fluidity rau kev tua hluav taws., thiab tib yam li yav dhau los ua npuas ncauj yas hluav taws tsheb, raws li kev kaw haujlwm, chav ua haujlwm, dej txias ua haujlwm sib tshooj sib tshooj kom ua tiav lub hom phiaj ntawm kev tua hluav taws.
Kev tua hluav taws tsim nyog thiab ceev ceev hauv thaj chaw uas cov kav dej hauv tsev qiv ntawv, cov tsev khaws ntaub ntawv keeb kwm, thiab cov cuab yeej siv siab thiab cov cuab yeej siv nyob hauv - CO2 tsheb tua hluav taws.
Kev sau cov phau ntawv nyob rau hauv lub tsev qiv ntawv raj thiab cov khoom sau muaj txiaj ntsig hauv keeb kwm tsev cia puav pheej yog cov neeg muaj nyiaj txiag ntawm sab ntsuj plig.Ntxiv nrog rau kev tua hluav taws tam sim ntawd, nws yog ib qho tsim nyog yuav tsum tswj cov khoom no kom ntau li ntau tau.Tsis tas li ntawd, tseem muaj nqi rau kev ua tej yam twj paj nruag thiab meters.Yog tias nws siab dhau lawm lossis cov khoom siv muaj lub luag haujlwm tseem ceeb, nws yuav tsum tau ua qhov tseem ceeb los tswj lawv thaum tua hluav taws.
Yog li ntawd, cov phiaj xwm kev nyab xeeb hluav taws yav dhau los tsis tuaj yeem ua tiav lub hom phiaj, thiab cov tsheb tua hluav taws CO2 yuav tsum tau yug los ntawm qee lub sijhawm.Tej zaum tam sim no CO2 hluav taws tua hluav taws yog txhua daim ntawv thov loj.Vim cov kua roj tsis ignite thiab tsis hlawv, nws tsis yog-conductive thiab tsis-corrosive.Lub sij hawm zom thiab nqus cov cua kub ntau, kom ua tiav lub hom phiaj ntawm kev ua kom txias sai.Tsis tas li ntawd, nws tsis yooj yim rau kev rhuav tshem cov khoom uas tsis yog cov khoom siv hlawv.Ntau cov dej ntws tawm CO2 yuav dilute cov dej ntawm cov kua oxygen, thiaj li ua tiav lub hom phiaj ntawm kev tua hluav taws tam sim.
Kev kub ceev ceev ntawm cov khoom siv hluav taws xob induction hluav taws kub sib tsoo - hmoov hluav taws tsheb
Cov tsheb tua hluav taws no yog cov khoom siv hluav taws xob ntxiv rau cov khoom siv hluav taws xob ua npuas dej, thiab cov khoom siv hluav taws xob hloov kho tshiab rau cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob induction, thiab tsim nyog rau cov khoom siv hluav taws xob loj thiab nruab nrab.
Raws li kev siv cov volatiles ntawm cov organic teeb meem nyob rau hauv cov hmoov los tua hluav taws, cov txheej ntawm iav av txheej kuj yuav ua tau nyob rau hauv high kub, thiab ces cov pa barrier yuav siv tau los tua hluav taws.Nws yog siv rau hauv cov hluav taws tua hluav taws ntawm tib lub teev raws li CO2, thiab nws yog ib qho ntawm cov hluav taws kub uas tsim nyog.
Cov tsheb tua hluav taws sib txawv yog siv los cawm cov hluav taws kub sib tsoo hauv cov xwm txheej sib txawv, thiab lub neej niaj hnub feem ntau nyuaj.Nws yog qhov tsim nyog thiab ua tau zoo kom phim cov tsheb tua hluav taws sib txawv los ua cov haujlwm cawm nyuaj.
