Chav roj teeb yog ib qho chaw uas cov roj teeb khaws cia. Raws li lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lead-acid roj teeb, qhov zoo active khoom ntawm lead-acid cia yog lead dioxide, cov tsis zoo active tshuaj yog sponge lead, thiab cov electrolyte yog dilute sulfuric acid tov. Thaum them nyiaj rau 70% ~ 80% ntawm cov hluav taws xob, qhov zoo electrode pib tsim cov pa oxygen, thiab thaum lub sij hawm them tag nrho li ntawm 90%, qhov tsis zoo electrode pib tsim hydrogen. Hydrogen yog cov khoom tawg yooj yim thiab tawg hauv chav kawm A, qhov txwv tsis pub tawg hauv huab cua yog 4.1% ~ 74.1%, qhov kub ntawm qhov hluav taws kub yog li 450 ° C, yog li cov concentration ntawm hydrogen hauv chav them nyiaj yog yooj yim mus txog qhov tawg txwv, thiab lub ignition qhov chaw yuav tsim tawg.
Qhov tawg txwv ntau ntawm hydrogen yog qhov loj, thaum nws tov nrog cov roj chlorine, nws tuaj yeem tawg thaum raug tshav kub lossis tshav ntuj; Yog tias tov nrog fluorine, nws tawg tam sim ntawd. Nws lub zog hluav taws xob tsawg heev, tsuas yog 0.019mJ, cov nplaim taws qhib me me, xws li acrylic, dacron thiab lwm yam khaub ncaws vim muaj kev sib txhuam los ntawm cov hluav taws xob hluav taws xob, tuaj yeem ua rau tawg, ntxiv rau kev ua phem yuav ua rau tawg. . Yog li ntawd, cov chaw tsim hluav taws xob thiab cov chaw tsim hluav taws xob uas muaj cov roj teeb lead-acid yuav tsum tau nruab hydrogen detectors los saib xyuas cov concentration ntawm hydrogen hauv chav roj teeb txhua lub sijhawm.
Cov kev ntsuas rau kev tiv thaiv hluav taws thiab tawg nyob rau hauv lub chav tsev roj teeb lead-acid yog raws li nram no:
1. Txhim kho qhov cua ntawm chav roj teeb
Txhawm rau tiv thaiv cov khoom tawg ntawm hydrogen hauv chav roj teeb, cov chaw ua pa txaus yuav tsum tau teeb tsa hauv chav kom cov ntsiab lus hydrogen hauv chav roj teeb yuav tsis ncav cuag qhov kev phom sij tawg.
2. Tiv thaiv kom tsis txhob muaj hydrogen tawm ntawm cov ces kaum tuag ntawm lub roj teeb chamber
Vim tias hydrogen yog sib zog dua huab cua, feem ntau ntawm nws accumulates nyob rau hauv qab nthab. Yog li ntawd, lub qab nthab ntawm chav roj teeb yuav tsum tsis txhob ua pa. Thaum lub qab nthab tau muab faib ua ob peb ntu los ntawm lub girder ntawm hauv pem teb, hydrogen yog ib qho yooj yim mus sau nyob rau hauv qhov chaw ntawm lub beam thiab beam. Yog li ntawd, txhua cov ntaub ntawv yuav tsum muaj lub kiv cua kom tso tawm cov hydrogen khaws cia nyob rau sab sauv ntawm qhov nruab nrab.
3. Cov khoom siv hluav taws xob tawg yuav tsum tau siv hauv tsev
Txhawm rau tiv thaiv kev tawg los ntawm hluav taws xob hluav taws xob, cov khoom siv hluav taws xob tawg yuav tsum tau siv hauv chav roj teeb. Xws li cov hluav taws xob hloov hluav taws xob, tus pins, lub qhov (socket), fuses, thiab lwm yam yog cov khoom siv hluav taws xob tawg uas tsis tsim cov nplaim taws. Cov teeb hluav taws xob tawg yuav tsum tau siv rau lub teeb pom kev ntawm chav roj teeb, thiab cov hlau lead yuav tsum tau siv rau lub teeb pom kev zoo.
4. Nruab lub tswb ntsuas roj
Hydrogen detection tswb yog tsom rau kev tshawb nrhiav hydrogen leak concentration ceeb toom ntaus ntawv, yog tsim los ntawm roj tswb tswj thiab roj detector ob qhov chaw, gas detector ntsia rau hauv cov pa xau nrhiav qhov chaw, los ntawm cov tub ntxhais tivthaiv roj sensor, mus cuag real-time nrhiav roj. concentration, kuj tuaj yeem ua haujlwm ntawm nws tus kheej. Lub tswb hluav taws xob tuaj yeem muab tso rau hauv chav ua haujlwm, tau txais qhov ntsuas pom los ntawm lub ntsuas roj, thiab paub txog cov ntsiab lus pom thiab lub suab thiab lub teeb ceeb toom ua haujlwm tom qab qhov siab tshaj tus qauv, thiab tuaj yeem txuas cov cua ntxuam, upload PLC, DCS, kev tiv thaiv hluav taws, thiab lwm yam.
