Diesel Oxidation Catalyst

Diesel Oxidation Catalyst (DOC) yog ib qho khoom siv nruab rau hauv lub tshuab hluav taws xob diesel emission system. Nws yog ib chav ua kom huv huv pa uas siv cov ceramic los yog hlau ua cov khoom thauj thiab thauj cov khoom siv xws li lub ntiaj teb tsis tshua muaj, cov hlau muaj txiaj ntsig lossis hlau oxides. Nws lub luag haujlwm tseem ceeb yog hloov cov khoom tsis zoo uas tso tawm tom qab cov hluav taws xob hluav taws xob rau hauv cov khoom tsis zoo los ntawm cov tshuaj tiv thaiv catalytic. Tshwj xeeb, DOC tuaj yeem oxidize carbon monoxide (CO), hydrocarbons (HC) thiab qee cov sulfur oxides (SOF), hloov cov emissions mus rau carbon dioxide (CO₂), dej (H₂Othiab sulfates (SO_x).

Kev hloov dua siab tshiab ntawm DOC catalyst rau cov pa phem sib txawv yog kwv yees li: 70-90% rau carbon monoxide (CO), 60-80% rau hydrocarbons (HC), thiab 40-50% rau sulfur oxides (SOF) . Kev siv DOC thiab DPF ua ke tuaj yeem coj tawm qhov zoo ntawm txhua lub thev naus laus zis thaum kov yeej cov kev txwv ntawm ib qho thev naus laus zis. Doc pab kom nce cov cua sov los ntawm catalytic oxidation, yog qhov tsim nyog siv cua sov ntawm DPF thiab tiv thaiv kev sib txuam ntawm kev muaj teeb meem. Cov txheej txheem rov tsim dua tshiab ntawm DPF tuaj yeem ua tau nyob rau hauv ob txoj kev: passive regeneration thiab active regeneration. Passive regeneration siv cov cua sov hauv cov pa tso pa thiabTSIS MUAJ₂Raws li cov oxidant ntawm qhov kub thiab txias, thaum lub sij hawm active regeneration yuav tsum tau lub internal kub ntawm DPF yuav tsum tau nce los ntawm roj txhaj tshuaj los yog lwm yam sab nraud cua sov txhais tau tias kom ua tiav combustion ntawm cov khoom.

Diesel tsheb tshem tawm kev kho mob: DOC catalyst yog ib qho tseem ceeb hauv kev tso pa tawm tom qab kev kho mob ntawm cov tsheb diesel, uas yuav pab ua kom tau raws li cov cai nruj dua.

Tsis-txoj kev mobile machinery tso pa kev kho mob: Tsis tshua muaj lub ntiaj teb catalysts kuj siv nyob rau hauv cov pa kev kho mob ntawm tsis-txoj kev mobile machinery los txo cov concentration ntawm cov pa phem nyob rau hauv lub cav tso pa tawm.

Kev kho cov roj khib nyiab: Txawm hais tias DOC catalysts feem ntau yog siv rau kev kho tsheb hauv tsheb, lawv cov hauv paus ntsiab lus thiab cov thev naus laus zis kuj tseem tuaj yeem txuas mus rau qee qhov kev siv hluav taws xob kho hluav taws xob los txo cov emission ntawm cov pa phem.

Jinan Jingheng Machinery Equipment Co., Ltd., raws li lub tuam txhab muag khoom thiab kev pabcuam siab, tshwj xeeb hauv kev tsim, kev teeb tsa, thiab kev ua haujlwm txij nkawm ntawm lub tshuab hluav taws xob teeb thiab tso tawm denitrification tej yaam num. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv ntawm lub zog, kev lag luam, thiab kev tiv thaiv ib puag ncig, lub tuam txhab tau cog lus los muab cov neeg siv khoom nrog EPC tag nrho cov kev daws teeb meem thiab cov phiaj xwm tig rau cov roj siv dav dav, kev siv hluav taws xob ua ke thiab hluav taws xob (CHP), cov kav dej phwj tuaj. , thiab tso pa tawm tom qab kho.
