Cov kua ammonia cia tank
Cov kua ammonia muaj nyob rau hauv daim ntawv teev cov tshuaj lom neeg vim nws cov nplaim taws, tawg, thiab muaj kuab lom.Raws li "Kev Tshawb Fawb Txog Cov Khoom Siv Hluav Taws Xob Tseem Ceeb ntawm Cov Khoom Siv Hluav Taws Xob" (GB18218-2009), qhov ntim tseem ceeb ntawm ammonia ntau dua 10 tons *** yog qhov tseem ceeb ntawm kev phom sij.Tag nrho cov kua ammonia cia tank yog cais raws li peb hom ntawm cov hlab ntsha siab.Tam sim no txheeb xyuas cov yam ntxwv thiab kev phom sij thaum lub sijhawm tsim khoom thiab kev ua haujlwm ntawm cov kua ammonia cia tank, thiab qhia qee qhov kev tiv thaiv thiab kev ntsuas kub ceev kom tsis txhob muaj xwm txheej.
Kev tsom xam ntawm cov kua ammonia cia tank thaum ua haujlwm
Kev phom sij ntawm ammonia
Ammonia yog cov roj tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw ntxhiab, uas yooj yim liquefied rau hauv cov kua ammonia.Ammonia yog sib dua li huab cua thiab yooj yim soluble hauv dej.Txij li cov kua ammonia yog yooj yim volatile rau hauv ammonia gas, thaum ammonia thiab huab cua sib xyaw rau ib qho piv txwv, nws tuaj yeem raug qhib nplaim taws, qhov siab tshaj plaws yog 15-27%, nyob rau hauv huab cua ambient ntawm lub rhiav ***** * Qhov tso cai pom zoo yog 30mg / m3.Cov pa roj ammonia tuaj yeem ua rau muaj tshuaj lom, ua rau lub qhov muag, lub ntsws mucosa, lossis tawv nqaij, thiab muaj kev phom sij ntawm cov tshuaj lom neeg mob khaub thuas.
Kev pheej hmoo ntawm kev tsim khoom thiab kev ua haujlwm
1. Ammonia qib tswj
Yog tias qhov tso tawm ammonia nrawm dhau, cov kua dej tswj kev ua haujlwm tsawg dhau, lossis lwm yam kev tswj xyuas tsis ua haujlwm, thiab lwm yam, cov roj hluavtaws hluavtaws yuav khiav mus rau hauv cov kua ammonia cia tank, uas ua rau overpressure hauv lub tank cia thiab ib tug loj npaum li cas ntawm ammonia to, uas yog heev teeb meem.Kev tswj cov qib ammonia yog qhov tseem ceeb heev.
2. Cia muaj peev xwm
Lub peev xwm cia ntawm cov kua ammonia cia tank tshaj 85% ntawm qhov ntim ntawm lub tank cia, thiab lub siab tshaj qhov ntsuas qhov ntsuas qhov ntau lossis kev ua haujlwm tau ua nyob rau hauv cov kua ammonia inverted tank.Yog hais tias cov txheej txheem thiab cov kauj ruam tsis nruj me ntsis raws li cov kev cai ntawm kev khiav hauj lwm, overpressure to tshwm sim***** * xwm txheej.
3. Ua kua ammonia filling
Thaum cov kua ammonia tau sau, overfilling tsis ua raws li cov kev cai, thiab cov blasting ntawm lub raj xa dej yuav ua rau muaj kev sib tsoo thiab lom.
Kev soj ntsuam kev puas tsuaj ntawm cov khoom siv thiab cov chaw
1. Kev tsim, kev tshuaj xyuas, thiab kev saib xyuas cov kua ammonia cia tso tsheb hlau luam yog ploj lossis tsis nyob hauv qhov chaw, thiab cov khoom siv kev nyab xeeb xws li qib ntsuas, ntsuas ntsuas, thiab kev nyab xeeb li qub yog qhov tsis zoo lossis zais, uas tuaj yeem ua rau muaj kev sib tsoo ntawm lub tank.
2. Thaum lub caij ntuj sov los yog thaum kub siab, cov kua ammonia cia tank tsis tau nruab nrog awnings, tsau cov dej txias txias thiab lwm yam kev tiv thaiv raws li xav tau, uas yuav ua rau overpressure to ntawm lub tank cia.
3. Kev puas tsuaj lossis tsis ua haujlwm ntawm kev tiv thaiv xob laim thiab cov chaw tiv thaiv zoo li qub lossis hauv av yuav ua rau hluav taws xob poob rau lub tank cia.
4. Qhov tsis ua hauj lwm ntawm cov txheej txheem tsim lub tswb, kev cuam tshuam, kev kub ntxhov thaum muaj xwm txheej ceev, hluav taws kub thiab tshuaj lom lub tswb ceeb toom thiab lwm yam khoom siv yuav ua rau muaj kev sib tsoo overpressure los yog loj ntawm lub tank cia.
Kev tiv thaiv kev kub ntxhov
Kev tiv thaiv kev tiv thaiv rau cov txheej txheem ntau lawm
1. Ua raws li cov txheej txheem ua haujlwm nruj me ntsis
Ua tib zoo saib xyuas kev ua haujlwm ntawm kev tso tawm ammonia hauv cov khoom siv hluavtaws, tswj cov kua theem ntawm kev sib cais ntawm cov kab mob khaub thuas thiab ammonia, ua kom cov kua theem ruaj khov nyob rau hauv thaj tsam ntawm 1/3 txog 2/3, thiab tiv thaiv cov kua theem los ntawm qis heev lossis siab dhau lawm.
2. nruj me ntsis tswj lub siab ntawm cov kua ammonia cia tank
Qhov ntim ntawm cov kua ammonia yuav tsum tsis pub tshaj 85% ntawm lub tank ntim.Thaum lub sij hawm ib txwm tsim, cov kua ammonia cia tank yuav tsum tau tswj nyob rau hauv ib tug tsawg theem, feem ntau nyob rau hauv 30% ntawm lub ntim ruaj ntseg ntim, kom tsis txhob ammonia cia vim ambient kub.Kev nthuav dav thiab siab nce yuav ua rau muaj kev kub ntxhov hauv lub tank cia.
3. Kev ceev faj rau cov kua ammonia filling
Cov neeg ua haujlwm uas txhim kho ammonia yuav tsum dhau kev kawm txog kev nyab xeeb thiab kev cob qhia ua ntej lawv tuaj yeem nqa lawv txoj haujlwm.Lawv yuav tsum paub txog kev ua tau zoo, cov yam ntxwv, cov txheej txheem kev ua haujlwm, cov qauv siv, cov qauv kev ua haujlwm, cov yam ntxwv txaus ntshai ntawm cov kua ammonia thiab ntsuas kev kho mob thaum muaj xwm txheej ceev.
Ua ntej sau, qhov siv tau ntawm daim ntawv pov thawj xws li kev kuaj xyuas lub cev tank, daim ntawv tso cai siv lub tank, daim ntawv tsav tsheb, daim ntawv pov thawj escort, thiab daim ntawv tso cai thauj mus los yuav tsum raug txheeb xyuas.Cov khoom siv kev nyab xeeb yuav tsum ua kom tiav thiab rhiab, thiab kev tshuaj xyuas yuav tsum tsim nyog;lub siab nyob rau hauv lub tanker ua ntej filling yuav tsum tsawg.Tsawg dua 0.05 MPa;kev ua haujlwm ntawm ammonia txuas pipeline yuav tsum tau kuaj xyuas.
Cov neeg ua haujlwm uas txhim kho ammonia yuav tsum nruj me ntsis ua raws li cov txheej txheem kev khiav hauj lwm ntawm cov kua ammonia cia tank, thiab xyuam xim rau lub ntim ntim tsis pub tshaj 85% ntawm lub tank ntim ntim thaum sau.
Cov neeg ua haujlwm uas txhim kho ammonia yuav tsum hnav lub qhov ncauj qhov ntswg thiab cov hnab looj tes tiv thaiv;lub xaib yuav tsum tau nruab nrog cov khoom siv tua hluav taws thiab cov khoom tiv thaiv roj;Thaum lub sij hawm txhaws, lawv yuav tsum tsis txhob tawm ntawm qhov chaw, thiab ntxiv dag zog rau kev soj ntsuam ntawm lub tank tsheb siab, cov kav dej flanges rau cov dej xau, thiab lwm yam., tank tsheb gas Recycle nws mus rau qhov system raws li thiab tsis tso tawm ntawm qhov xav tau.Yog tias muaj qhov xwm txheej txawv txav xws li xau, tso tseg tam sim ntawd, thiab siv cov kev ntsuas zoo los tiv thaiv cov xwm txheej tsis tau xav txog.
Kev tshuaj xyuas txhua hnub ntawm ammonia installation cov chaw, kev ntsuas thiab cov txheej txheem yuav tsum tau ua txhua hnub, thiab kev tshuaj xyuas thiab sau cov ntaub ntawv yuav tsum tau ua.
