Rau VOC gas detectors, hom qauv twg muaj?
Qhov cuam tshuam ntawm kev lag luam qhov chaw VOC emissions ntawm cov pa phem nyob ib puag ncig yog ncaj qha thiab muaj cov pa phem pom tseeb. Yog li ntawd, txhawm rau tiv thaiv thiab tswj tus qauv emissions ntawm VOC, nws yog ib qho tsim nyog yuav tsum siv cov cuab yeej kuaj xyuas VOC rau kev saib xyuas thiab tswj, uas tuaj yeem ua tiav kev txhim kho tseem ceeb. Tshwj xeeb tshaj yog rau cov lag luam tseem ceeb hauv kev lag luam, qhov kev faib ua feem ntawm VOC tsim los ntawm kev lag luam yog qhov loj, feem ntau muaj kev sib koom ua ke emissions nrog siab concentrations, yooj yim rau kev sau thiab txheej txheem, thiab paub tab kho technologies. VOC detectors yog lub qhov muag ntawm VOC kev lag luam kho mob, saib xyuas hauv lub sijhawm tiag tiag seb qhov concentration ntawm VOC tshaj tus qauv. Yog li dab tsi yog cov qauv qauv rau VOC detectors? Koj puas paub?
Tam sim no, muaj peb txoj hauv kev ua piv txwv rau VOC ntes, uas yog diffusion sampling, twj tso kua mis sampling, thiab pipeline sampling.
1. Diffusion hom
Lub npe hu ua diffusion hom yog hais txog kev tshawb nrhiav online txuas ntxiv ntawm VOC thiab hom kev kuaj dawb dawb diffusion;
Hais txog diffusion sampling, kev kuaj pom yog tsuas yog ua los ntawm cov roj ntsha ntuj. Thaum cov roj nkag mus rau hauv cov roj chamber ntawm lub tshuab ntes, qhov ntsuas tau txais kev nkag siab thiab muab cov lus pom zoo hauv lub sijhawm ntawm kev saib xyuas qhov tseem ceeb kom ua tiav lub hom phiaj ntawm kev tshawb nrhiav.
2. Lub tshuab nqus tsev twj
Lub twj tso kua mis sab nraud tuaj yeem nruab nrog lub twj tso kua mis ntws tawm rau cov cua nkag thiab qhov hluav taws xob lossis lub twj tso kua mis sab hauv kom ua tiav lub twj tso kua mis nqus kom pom txoj kev (cua twj tso kua mis yeem);
Uas yog hais tias, lub twj tso kua mis suction sampling yog ib tug roj sensor uas ntxiv ib tug ntxiv suction twj tso kua mis rau lub detector, cia siab rau lub suction quab yuam ntawm lub twj tso kua mis kom sai nqus cov pa mus rau hauv lub gas chamber, thiaj li yuav ua kom tiav nrhiav tau. (Lub tshuab nqus tsev vacuum kuaj cov tshuab nqus tsev twj tso kua mis, muab kev ruaj khov thiab ntev lub tshuab nqus tsev vacuum, thiab lub tshuab nqus tsev twj tso kua mis muaj lub neej ntev, tsis muaj suab nrov, thiab 5 adjustable ceev ntau yam.)
3. Kev sojntsuam hom
Qws sampling yog ua tiav los ntawm kev siv thiab nruab nrog ib tug 1M ntev freely expandable hlau pas nrig rau sampling, nrog ib tug nrhiav kom paub cov nyhuv ntawm "mus txog lub ntuj thiab lub ntiaj teb". Zoo li lub tshuab nqus tsev twj tso kua mis nqus cov pa ntsuas ntawm Shenzhen Guoan, lub tshuab nqus tsev twj ntawm lub tshuab nqus tsev twj tso kua mis kuj muaj kev tiv thaiv tus kheej.
