Inline density meters yog qhov kev ua si hloov pauv ntawm denitration hauv fais fab nroj tsuag thaum muaj kev lag luam. Cov kev ntsuas kev txawj ntse tshiab no tso cai rau cov neeg ua haujlwm saib xyuas qhov ceev ntawm lub sijhawm tiag tiag, thiab cov cuab yeej tseem ceeb hais txog cov txheej txheem tshuaj lom neeg. Nws yog ib qho tseem ceeb rau cov neeg ua haujlwm yuav tsum tau ntsib nrog cov teeb meem kev ua haujlwm raws li kev soj ntsuam ntau dua thiab nruj dua ib puag ncig cov cai. Saib rau cov xwm txheej ntxaws uas lawv ua haujlwm los daws cov teeb meem kev lag luam nyuaj thiab tshem tawm kev ua haujlwm nyuaj tab sis rov ua haujlwm dua.
Tricky Technical Dilemmas hauv Denitration
Kev hloov pauv hauv emissions ntawm nitrogen oxide (NOx) tsis yog ib txoj haujlwm yooj yim. Nitrogen oxide tsis tuaj yeem tshem tawm tag nrho, txawm nyob hauv cov thee hluav taws xob, roj hlawv lossis txawm tias biomass fueling nroj tsuag. Kev tswj cov emissions nrog precision yog muaj feem xyuam rau Selective Catalytic Reduction (SCR) los yog Selective Non-Catalytic Reduction (SNCR), nyob rau hauv uas reagents ntxiv rau flue gas kwj rau ntxiv cov tshuaj tiv thaiv. Txawm li cas los xij, kev tshuaj xyuas qhov tseeb ntawm lub sijhawm tiag tiag ntsib ntau qhov kev sib tw los ntawm kev ua haujlwm nyuaj. Qhov tsis raug ntawm kev ntsuas yuav ua rau ammonia plam thiab cov khoom pov tseg.
Lonnmeter tsim thiab tsim cov inline ceev meterrau kev ntsuas kev ntsuas tsis tu ncua kom tsis txhob muaj tib neeg yuam kev hauv kev coj ua ib txwm muaj. Tib neeg sampling tso siab rau ntau qhov kev kuaj xyuas ib ntus thiab kev kwv yees tsis ncaj. Xws li ibOnline density meterNws muaj peev xwm txheeb xyuas qhov hloov pauv me ntsis hauv kev saib xyuas kom zoo los pab kho qhov tseeb, ua kom tag nrho cov txheej txheem denitration ruaj khov thiab ua haujlwm tau zoo.
Tsis tas li ntawd, nws kuj tseem ua haujlwm hauv kev muab cov kev ntsuas uas qhia txog kev sib xyaw zoo, reagent sib xws thiab txawm tias tus nqi ntws. Piv txwv li, inconsistency ntawm urea kwj rau dissolving rau hauv dej cuam tshuam cov tshuaj tiv thaiv chemistry. Los ntawm kev saib xyuas cov slurry ncaj qha rau hauv cov raj xa dej, inline density meters kom ntseeg tau tias qhov xav tau concentration yog khaws cia los ntawm kev khaws cia rau kev txhaj tshuaj, txo qhov kev pheej hmoo ntawm cov txheej txheem tsis muaj txiaj ntsig lossis kev tsis ua raws li ib puag ncig.
Pom zoo Industrial Density Meters
Txhim kho Automation hauv Denitration thiab System Reliability
Ploj mus yog cov hnub uas cov neeg cog qoob loo yuav tsum tau tso siab rau cov kev pab cuam los ntawm kev siv tshuaj reagent zoo. Niaj hnub nimno inline density meters integrate seamlessly mus rau advanced Distributed Control Systems (DCS) los yog Programmable Logic Controllers (PLC), tso cai rau ib tug tag nrho automated tawm tswv yim voj. Thaum kev nyeem ntawv ceev sib txawv ntawm qhov preset ntau, lub kaw lus cia li kho cov reagent txaus tus nqi lossis dilutes cov tshuaj raws li xav tau. Qhov no automation tsis tsuas yog txo lub nra ntawm cov neeg ua haujlwm tab sis kuj tshem tawm cov kev ncua sij hawm cuam tshuam nrog tib neeg kev txiav txim siab.
Nws yog ib qho tseem ceeb kom sib npaug cov kwj dej hauv kev ua ke desulfurization thiab denitration ua, qhov twg cov kua qaub slurry thiab ammonia daws tau siv tib lub sijhawm. Kev saib xyuas qhov ntom ntawm ob cov kua dej no yog qhov yuav tsum tau ua ua ntej rau kev ua haujlwm ntawm desulfurization thiab denitration. Qhov kev sib koom ua ke no pab tiv thaiv cov teeb meem xws li sedimentation hauv cov kav dej limestone lossis overdosing ntawm ammonia, ob qho tib si uas tuaj yeem ua rau raug nqi kaw lossis kev saib xyuas.
Dhau li, xws li cov inline density metres meters yog kev tiv thaiv rau cov kev mob hnyav hauv cov nroj tsuag fais fab. Rau cov qauv tsim tshwj xeeb kom tiv taus qhov kub thiab txias, lawv yog qhov zoo tshaj plaws los tswj cov tshuaj corrosive hauv cov xwm txheej nyuaj xws li flue gas denitration system.
Daim ntawv thov ntawm Inline Density Meters hauv Coal-Fired Power Plant
Feem ntau, cov hluav taws kub hluav taws xob hluav taws xob cov nroj tsuag muaj kev thab plaub hauv cov kev ntsuas ceev thiab tsis muaj xws li tab sis tsis txwv rau cov nplais clogging, ammonia plam thiab muaj peev xwm tu. Lub diav rawg inline density meter yog qhov cuab yeej ntse zoo tshaj plaws rau ob qho tib si ammonia txhaj kab thiab limestone slurry system.
Cov txiaj ntsig tau hloov pauv. Kev saib xyuas qhov ceev ntawm lub sijhawm tau tso cai rau cov nroj tsuag kom zoo-tu reagent dosing nrog qhov tsis tau pom dua. Ammonia plam qib poob ntau dua 90%, thaum NOx txo qhov ua tau zoo tshaj 92%. Cov limestone slurry, uas yav dhau los ua rau scaling thiab blockages, tau khaws cia ntawm qhov pom kev ntom ntom, tshem tawm cov kev saib xyuas tsis tu ncua thiab txo qis qis dua 20%. Cov kev txhim kho no tsis tsuas yog coj cov nroj tsuag ua raws li cov qauv ib puag ncig tab sis kuj txo cov nqi ua haujlwm los ntawm 15%.
Vim li cas Inline Density Meters yog qhov tseem ceeb
Dab tsi teev inline ceev ntsuas sib nrug los ntawm lwm yam kev soj ntsuam kev daws teeb meem yog lawv versatility thiab adaptability. Lawv tsis txwv rau denitration; lawv daim ntawv thov txuas mus rau txhua txoj kev lag luam uas xav tau kev tswj xyuas cov kua dej. Hauv cov ntsiab lus ntawm cov chaw tsim hluav taws xob, qhov no suav nrog cov tshuab desulfurization, kev kho dej khib nyiab, thiab kev siv roj sib xyaw. Lawv lub peev xwm los muab cov ntaub ntawv tiag tiag, raug, thiab ua tau zoo ua rau lawv yog lub hauv paus ntawm kev ua kom zoo dua qub.
Los ntawm kev siv cov cuab yeej no, cov nroj tsuag hluav taws xob tuaj yeem ua tiav ib theem ntawm kev tswj hwm uas yav tas los tsis tuaj yeem ua tiav. Cov txiaj ntsig txuas ntxiv dhau ntawm kev ua raws cai thiab kev ua haujlwm; lawv kuj suav nrog kev txhim kho cov cuab yeej siv tau ntev, txo cov nqi kho, thiab txhim kho kev ruaj khov. Rau cov neeg ua haujlwm uas muaj nuj nqis rau kev ua tau zoo thiab kev lav phib xaub ib puag ncig, inline density meters tsis yog kev nqis peev xwb - lawv yog qhov tsim nyog.
