Nrog rau kev txhawj xeeb thoob ntiaj teb rau kev tiv thaiv ib puag ncig, kev txo cov pa phem tau dhau los ua qhov teeb meem tseem ceeb hauv kev lag luam diesel generator. Kev siv cov thev naus laus zis kho cov pa phem yog qhov tseem ceeb heev los txo cov pa phem. Daim ntawv no yuav tham txog qhov tseem ceeb ntawmcov pa roj tawmkev kho mob ntawmcov khoom siv hluav taws xob dieselthiab yuav ua li cas kom txo tau cov pa phem.
Ua ntej tshaj plaws, peb yuav tsum nkag siab txog cov tshuaj lom neeg hauv cov pa roj tawm ntawmcov tshuab hluav taws xob diesel. Cov tshuab hluav taws xob dieselThaum lawv hlawv roj diesel, lawv tsim ntau yam pa phem, suav nrog nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM) thiab carbon monoxide (CO). Cov tshuaj phem no muaj peev xwm ua rau tib neeg noj qab haus huv thiab ib puag ncig puas tsuaj.
Yuav kom txo tau cov pa phem,cov khoom siv hluav taws xob dieselyuav tsum tau siv cov thev naus laus zis kho cov pa roj av. Ntawm cov thev naus laus zis feem ntau yog kev txo cov pa roj carbon dioxide (SCR) thiab cov cuab yeej cuab tam particulate (DPF). SCR thev naus laus zis hloov cov nitrogen oxides mus ua cov nitrogen thiab dej tsis muaj teeb meem los ntawm kev txhaj cov kua urea rau hauv cov pa roj tawm. DPF thev naus laus zis ntes thiab lim cov khoom me me kom tiv thaiv lawv kom tsis txhob nkag mus rau hauv huab cua.
Ntxiv rau kev siv tshuab kho cov pa roj tawm, kev ua haujlwm thiab kev saib xyuas cov tshuab hluav taws xob diesel kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txo cov pa phem. Ua ntej, kev saib xyuas thiab kev ntxuav tas li ntawmcov khoom siv hluav taws xobtuaj yeem ua kom nws ua haujlwm li qub thiab txo cov pa phem. Qhov thib ob, kev xaiv roj tsim nyog kuj tseem tuaj yeem txo cov pa phem. Kev siv cov roj diesel uas muaj cov sulfur tsawg thiab cov khoom ntxiv tuaj yeem txo cov pa phem sulfur dioxide thiab cov khoom me me. Tsis tas li ntawd, kev tswj hwm lub nra hnyav thiab cov tswv yim ua haujlwm kuj tseem tuaj yeem txo cov pa phem.
Yog xav paub ntxiv txog kev kho cov pa roj tawm ntawm cov pa rojcov khoom siv hluav taws xob diesel, kev txhawb nqa thiab kev saib xyuas ntawm tsoomfwv thiab cov koom haum tiv thaiv ib puag ncig kuj ua lub luag haujlwm tseem ceeb. Tsoomfwv tuaj yeem tsim cov cai thiab cov qauv tsim nyog los xav taucov khoom siv hluav taws xob dieselsiv cov thev naus laus zis kho cov pa roj tawm, thiab nplua rau cov chav uas tsis ua raws li cov qauv. Cov koom haum ib puag ncig tuaj yeem muab kev txhawb nqa thiab kev tawm tswv yim los txhawb kev txhim kho ntawmcov khoom siv hluav taws xob dieselkev lag luam hauv kev coj ua zoo dua rau ib puag ncig.
Hauv kev xaus lus, kev kho cov pa roj tawm ntawm cov tshuab hluav taws xob diesel yog qhov tseem ceeb los txo cov pa phem. Los ntawm kev siv cov thev naus laus zis kho cov pa phem, kev ua haujlwm thiab kev saib xyuas cov tshuab hluav taws xob, thiab kev txhawb nqa ntawm tsoomfwv thiab cov koom haum ib puag ncig, peb tuaj yeem txo cov pa phem ntawm cov tshuab hluav taws xob diesel thiabtiv thaiv ib puag ncigthiab tib neeg txoj kev noj qab haus huv.
