Hauv kev nrhiav kev tsim hluav taws xob huv dua, cov chaw tsim hluav taws xob tau siv cov thev naus laus zis siab heev los txo lawv qhov cuam tshuam rau ib puag ncig. Ib qho ntawm cov thev naus laus zis no yog kev siv cov tshuab flue gas desulfurization (FGD), uas ua lub luag haujlwm tseem ceeb hauv kev txo cov pa roj sulfur dioxide. Hauv plawv ntawm cov kab ke no yog FGD silicon carbide nozzles, uas yog ua los ntawm cov khoom siv ceramic hu ua silicon carbide. Cov blog no yuav tshawb nrhiav qhov tseem ceeb ntawm cov nozzles no, lawv cov kev hloov pauv tsim, thiab lawv qhov cuam tshuam rau kev ruaj khov ib puag ncig.
Cov nozzles silicon carbide yog tsim los pab txhawb cov txheej txheem desulfurization hauv cov chaw tsim hluav taws xob. Lawv lub luag haujlwm tseem ceeb yog tshem tawm cov sulfur dioxide (SO2) thiab lwm yam kuab paug phem los ntawm cov pa roj flue uas tso tawm thaum lub sijhawm hlawv roj fossil, tshwj xeeb tshaj yog thee. Qhov tseem ceeb ntawm cov txheej txheem no tsis tuaj yeem hais ntau dhau, vim tias sulfur dioxide yog qhov tseem ceeb ua rau muaj nag acid thiab huab cua paug, uas tuaj yeem muaj kev cuam tshuam loj heev rau tib neeg kev noj qab haus huv thiab ib puag ncig. Los ntawm kev siv FGD silicon carbide nozzles, cov chaw tsim hluav taws xob tuaj yeem txo cov pa phem thiab ua raws li cov cai ib puag ncig nruj.
Cov qauv tsim ntawm FGD silicon carbide nozzles tau tsim los ua kom zoo dua lawv cov kev ua tau zoo hauv ntau yam kev siv. Ob hom nozzle siv rau hauv cov txheej txheem desulfurization yog lub spiral full cone nozzle thiab lub vortex hollow cone nozzle. Lub spiral full cone nozzle yog tsim los tsim cov pa me me ntawm cov kua dej nqus, uas ua rau kev sib cuag ntawm cov kua thiab cov pa flue zoo dua, yog li ua kom cov txheej txheem desulfurization ua haujlwm tau zoo dua. Lub vortex hollow cone nozzle, ntawm qhov tod tes, tsim cov qauv tsuag swirling uas faib cov absorbent zoo dua, ua kom ntseeg tau tias kev kho mob ntawm cov pa flue zoo. Kev xaiv cov hom nozzle no nyob ntawm qhov xav tau tshwj xeeb ntawm lub chaw tsim hluav taws xob thiab cov yam ntxwv ntawm cov pa flue uas tau kho.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm silicon carbide ua cov khoom siv FGD nozzle yog nws qhov ruaj khov zoo heev thiab tiv taus kev hnav thiab xeb. Cov chaw tsim hluav taws xob feem ntau ua haujlwm hauv qab qhov xwm txheej hnyav, nrog rau qhov kub siab thiab cov khoom siv abrasive uas muaj nyob rau hauv cov pa roj flue. Silicon carbide nozzles tuaj yeem tiv taus cov chaw ib puag ncig nyuaj no, ua kom lub neej ua haujlwm ntev dua thiab txo cov nqi txij nkawm. Qhov kev ruaj khov no tsis yog tsuas yog txhim kho qhov ua tau zoo ntawm cov txheej txheem desulfurization, tab sis kuj pab txhim kho kev ntseeg siab tag nrho ntawm kev ua haujlwm ntawm cov chaw tsim hluav taws xob.
Ntxiv rau qhov desulfurization, FGD SiC nozzles kuj tseem ua lub luag haujlwm hauv denitrification thiab tshem tawm plua plav. Cov pa roj flue los ntawm cov chaw tsim hluav taws xob thee tsis yog tsuas yog muaj sulfur dioxide, tab sis kuj muaj nitrogen oxides (NOx) thiab particulate matter. Los ntawm kev sib txuas FGD systems nrog denitrification technology, cov chaw tsim hluav taws xob tuaj yeem kho ntau yam pa phem tib lub sijhawm, txhim kho huab cua zoo dua. Lub peev xwm los daws cov pa phem sib txawv no yog qhov tseem ceeb rau kev ua tau raws li cov qauv ib puag ncig thiab txo cov pa roj carbon tag nrho ntawm kev tsim hluav taws xob.
Kev siv cov FGD silicon carbide nozzles muaj feem cuam tshuam rau ib puag ncig ntau heev. Yog tsis muaj kev tshem tawm cov sulfur thiab denitrification zoo, cov pa roj flue los ntawm cov chaw tsim hluav taws xob tuaj yeem ua rau muaj kuab paug rau huab cua hnyav, ua rau muaj kab mob ua pa thiab kev puas tsuaj rau ib puag ncig. Tsis tas li ntawd, cov pa roj tsis tau lim los ntawm cov chaw tsim hluav taws xob uas siv thee tuaj yeem ua rau cov khoom kub ntawm cov roj turbine hauv cov txheej txheem sib xyaw ua ke puas tsuaj, ua rau muaj kev kho kim thiab kev ua haujlwm tsis zoo. Los ntawm kev nqis peev rau hauv cov thev naus laus zis FGD siab heev, cov chaw tsim hluav taws xob tsis tuaj yeem tiv thaiv ib puag ncig xwb, tab sis kuj txhim kho lawv cov kev ua haujlwm thiab kev lag luam.
Raws li lub ntiaj teb lub zog hluav taws xob txuas ntxiv mus, qhov xav tau cov khoom siv hluav taws xob huv dua thiab ruaj khov dua tau dhau los ua qhov ceev dua. FGD silicon carbide nozzles yog ib feem tseem ceeb ntawm kev hloov mus rau kev tsim hluav taws xob ntsuab. Los ntawm kev tshem tawm cov pa phem ntawm cov pa roj flue, cov nozzles no pab cov chaw tsim hluav taws xob ua tau raws li cov kev cai thiab pab txhawb rau lub ntiaj teb noj qab haus huv dua. Raws li thev naus laus zis nce qib thiab qhov kev thov rau kev saib xyuas ib puag ncig txuas ntxiv mus, lub luag haujlwm ntawm FGD silicon carbide nozzles hauv kev tawm tsam kev ua qias tuaj ntawm huab cua thiab kev hloov pauv huab cua yuav tsis muaj qhov tsis ntseeg tias tseem ceeb dua.
Hauv kev xaus lus, FGD Silicon Carbide Nozzle yog ib qho kev tsim kho tshiab tseem ceeb hauv kev tsim hluav taws xob desulfurization. Nws txoj kev tsim tshwj xeeb, kev ruaj khov, thiab kev ua haujlwm zoo hauv kev tshem tawm cov sulfur dioxide thiab lwm yam pa phem ua rau nws yog qhov tseem ceeb hauv kev nrhiav kev tsim hluav taws xob huv dua. Raws li cov chaw tsim hluav taws xob txuas ntxiv txais yuav cov thev naus laus zis siab heev los txo lawv cov kev cuam tshuam rau ib puag ncig, qhov tseem ceeb ntawm FGD Silicon Carbide Nozzles tsuas yog yuav nce ntxiv, paving txoj hauv kev rau yav tom ntej ruaj khov dua.
