Nyob ruaj ruaj SCR System

Nyob ruaj ruaj SCR System tuaj yeem siv rau ntau yam xwm txheej hauv thaj av, xws li cov chaw tsim hluav taws xob, lub tshuab hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam kev kho mob tom qab combustion. Nws yog tsim rau diesel, hnyav roj, biofuel thiab roj cav. Los ntawm kev teeb tsa thiab kev sib xyaw ua ke, nws tuaj yeem tswj tau ntau yam kuab paug thiab txo qis nitrogen oxide emissions ntau dua 98%.

1. Tswj System:

Saib xyuas thiab kho qhov kev ua haujlwm tsis zoo, xws li kub, siab, ntws thiab muab cov neeg sawv cev txo qis, txhawm rau txhim kho cov nyhuv denitrification.

Open-loop system: SEP/SNV, Close-loop system: SNQ

Teeb liab xa mus rau lub cav tswj thaum qhov ntsuas kub txog

2, Catalyst & Converter

Reaction chamber: Qhov chaw uas cov roj flue tuaj rau hauv kev sib cuag nrog tus neeg sawv cev txo qis, feem ntau yog cov yeeb nkab ntsug lossis kab rov tav nrog lub catalyst sab hauv.

SCR catalyst: Ib yam khoom siv los txhawb NOx txo cov tshuaj tiv thaiv, feem ntau yog cov hlau oxide lossis cov khoom sib xyaw ntawm cov hlau oxide thiab lwm yam khoom.

Lub ntsiab lus tseem ceeb ntawm SCR catalyst denitrification:

Urea tov dhau los ntawm lub raj sib tov, thiab cov ammonia uas ua los ntawm thermal decomposition / hydrolysis yog tag nrho tov nrog cov pa pa ntawm chav tsev thiab nkag mus rau lub reactor nruab nrog catalyst rau tshuaj tiv thaiv los tsim nitrogen thiab dej vapor. Qhov zoo NO_xkev hloov pauv tuaj yeem ncav cuag 98%.

Urea hydrolysis: CO (NH₂)₂ + H₂O = NH₂CO₂NH₄=2NH₃ + CO₂

Urea Pyrolysis: CONH₂)₂=NH₃+ HNCO, 8HNCO+6TSIS MUAJ₂=8CO₂+4H₂O+7N₂

>Cov tshuaj tiv thaiv ceev ceev: 2NO+2TSIS MUAJ₂+4NH₃= 4N₂+6H₂O

>Cov tshuaj tiv thaiv qeeb qeeb: 8NH₃ + 6TSIS MUAJ₂ = 7N₂ + 12H₂O

SCR catalyst:TiO₂matrix

Cua muab cua tshuab: Cua compressor CA cua compressor, Cov khoom siv cua valve DRV cua valve pawg.

Yog tias tus neeg siv khoom muab cov cua compressed, peb muab cov cua valve pab pawg; Yog tias tsis muaj cua compressed, peb muab cov cua compressor sib xyaw ua ke hauv SEP.

Reactant mov: Lub luag haujlwm xa cov reductant rau lub reactor kom paub meej txaus reductant kom tag nrho react nrog NOx. 40% huab hwm coj concentration, 32.5% urea daws yog xaiv tau. Urea noj yog cuam tshuam nrog kev tshem tawm cov nyhuv thiab qhov teeb meem debugging.

SEP system nplooj siab VPH urea twj tso kua mis, siab tshaj plaws txaus tus nqi 14L / h

Standard VNR urea twj tso kua mis, siab tshaj plaws txaus tus nqi 95/125/190L / h

Lub peev xwm loj urea twj tso kua mis, siab tshaj plaws txaus tus nqi 10, 000 L / h

Nyob ruaj ruaj SCR System muaj cov khoom lag luam nplua nuj, suav nrog cov tshuab sib xyaw ua ke, qhib-voj tswj tshuab thiab kaw-voj tswj tshuab. Nrog rau cov tswv yim tsim qauv, cov catalysts, cov tshuaj tiv thaiv chav, cov tshuab txhaj tshuaj thiab cov tshuab tswj tau txhua tus tuaj yeem hloov mus rau ntau lub zog sib txawv. Lub kaw-loop tswj qhov system siv cov cuab yeej tsim khoom hauv kev tshawb nrhiav kom ua tiav kev tswj hwm kev ua haujlwm siab, kev tu ncua ntev, thiab cov nqi tsis ua haujlwm kom zoo rau cov nqi khiav lag luam.

Jinan Jingheng Machinery Equipment Co., Ltd. yog lub tuam txhab kev muag khoom thiab kev pabcuam siab tshwj xeeb hauv kev tsim, kev teeb tsa thiab kev ua haujlwm thiab kev saib xyuas ntawm lub tshuab hluav taws xob teeb tsa thiab txhawb nqa cov dej ntws tawm denitrification. Nws muab cov neeg siv khoom nrog cov kev daws teeb meem xws li kev siv roj siv dav dav, kev sib xyaw ua ke kub thiab lub zog hluav taws xob (CHP), kev kho dej phwj tuaj, thiab tso pa tawm tom qab kho. Txhawm rau ua kom tau raws li cov neeg siv khoom xav tau ntau yam xws li lub zog, kev lag luam, thiab kev tiv thaiv ib puag ncig, lub tuam txhab nquag tshawb nrhiav chaw ruaj ntseg SCR System cov kev daws teeb meem rau kev ua liaj ua teb sib xyaw ua ke cua sov thiab hluav taws xob daim ntawv thov xws li tsev cog khoom, iav tsev, thiab tsev cog khoom.
