Iimitha zoxinano oluphakathi zitshintsha umdlalo we-denitration kwizikhululo zamandla ngexesha leenkqubo zoshishino. Ezi gauge zihlakaniphileyo zivumela abaqhubi ukuba bajonge uxinano ngexesha langempela, kunye nezixhobo ezibalulekileyo ezijongana neenkqubo ezintsonkothileyo zeekhemikhali. Kubalulekile ukuba abaqhubi bajongane nemingeni yokusebenza njengokulandela imithetho engqongqo ngakumbi nangakumbi yokusingqongileyo. Jonga iimeko ezineenkcukacha apho basebenza khona ukusombulula iingxaki zoshishino ezintsonkothileyo kunye nokususa umsebenzi onzima kodwa ophindaphindwayo.
Iingxaki Ezinzima Zobuchwephesha KwiDenitration
Ukulungiswa kokukhutshwa kwe-nitrogen oxide (NOx) akuyonto ilula. I-nitrogen oxide ayinakususwa ngokupheleleyo, nokuba kukwiindawo ezisebenzisa amalahle, ezitshiswe yioyile okanye ezisebenzisa i-biomass fuel. Ulawulo lokukhutshwa ko ...
Yila kwaye uvelise iLonnmeter imitha yoxinano olusemgceniukulinganisa rhoqo uxinaniso ukuze kuthintelwe iimpazamo zabantu kwisampulu yendabuko. Ukuthatha iisampulu ebantwini kuxhomekeke kakhulu ekuhlolweni okwenziwa rhoqo kunye noqikelelo olungathanga ngqo.imitha yoxinano kwi-intanethiiyakwazi ukubona utshintsho oluncinci ekubekweni kweliso loxinano ukunceda uhlengahlengiso oluchanekileyo, igcine yonke inkqubo yokususa i-denitration izinzile kwaye isebenza kakuhle.
Ukongeza, ikwasebenza ekunikezeni iiparameter ezibonisa umgangatho wokuxuba, ukuhambelana kwe-reagent kunye nesantya sokuhamba esilinganayo. Kwiimeko ezinjalo, ukungangqinelani komjelo we-urea ukuya ekunyibilikeni emanzini kuphazamisa ikhemistri yempendulo. Ngokujonga i-slurry ngqo kumbhobho, iimitha zoxinano oluphakathi ziqinisekisa ukuba uxinzelelo olufunekayo lugcinwa ukusuka kwindawo yokugcina ukuya kwi-injection, nto leyo enciphisa umngcipheko wokungasebenzi kakuhle kwenkqubo okanye ukungathobeli imiqathango yendalo.
Iimitha zoBuxinano eziCetyisiweyo kwiShishini
Ukuphucula ukuZenzekela kwiDenitration kunye nokuthembeka kwenkqubo
Ziphelile iintsuku apho abaqhubi bezityalo babexhomekeke kungenelelo olwenziwe ngesandla ukuze balungise i-reagent injection. Iimitha zoxinano zanamhlanje zidityaniswa ngokungenamthungo kwiiNkqubo zoLawulo eziDityanisiweyo eziphambili (DCS) okanye iiProgrammable Logic Controllers (PLC), zivumela i-feedback loop ezenzekelayo ngokupheleleyo. Xa ukufundwa koxinano kuphambuka kuluhlu olucwangcisiweyo, inkqubo ilungisa ngokuzenzekelayo isantya sokuhamba kwe-reagent okanye inciphise isisombululo njengoko kufuneka. Olu zenzekelayo alunciphisi nje kuphela umthwalo kubaqhubi kodwa lukwaphelisa ukulibaziseka okunxulumene nokwenza izigqibo ngabantu.
Kubalulekile ukulinganisela imijelo yeekhemikhali kwi-desulfurization kunye ne-denitration processing edibeneyo, apho kusetyenziswa i-lime slurry kunye ne-ammonia solutions ngaxeshanye. Ukubeka esweni uxinano lwala manzi mabini yimfuneko yokusebenza okuqhelekileyo kwe-desulfurization kunye ne-denitration. Eli nqanaba lokulungelelanisa linceda ukuthintela iingxaki eziqhelekileyo ezifana ne-sedimentation kwimibhobho ye-limestone okanye i-ammonia egqithisileyo, zombini ezi zinto zinokubangela ukuvalwa okanye ukulungiswa okubizayo.
Ngaphandle koko, ezi mitha zoxinano eziqinileyo ezingaphakathi ziyamelana neemeko ezinzima kwisityalo samandla. Ukuze uyilo olukhethekileyo lukwazi ukumelana namaqondo obushushu aphezulu kunye noxinzelelo, zilungele ukusingatha iikhemikhali ezirhabaxa kwiimeko ezinzima ezifana nenkqubo yokukhupha igesi yeflue.
Ukusetyenziswa kweeMeter zoBuxinano oluPhakathi kwiZityalo zoMbane ezisebenzisa amalahle
Ngokubanzi, izitishi zamandla ezisebenzisa amalahle zikhathazwa kukungasebenzi kakuhle kokulinganisa uxinano kunye neengxaki zobugcisa ezinxulumene noko kuluhlu, kubandakanya kodwa kungaphelelanga apho kuvaliwe khona imibhobho, ukutyibilika kwe-ammonia kunye nokugcinwa okunokwenzeka. Imitha yoxinano oluphakathi kwefoloko sisixhobo esikrelekrele esifanelekileyo kumgca wokujova i-ammonia kunye nenkqubo ye-limestone slurry.
Iziphumo bezitshintsha kakhulu. Ukubeka esweni uxinano ngexesha langempela kuvumele isityalo ukuba silungise idosi ye-reagent ngokuchanekileyo okungazange kwenzeke ngaphambili. Amanqanaba okutyibilika kwe-ammonia ehle ngaphezulu kwe-90%, ngelixa ukusebenza kakuhle kokunciphisa i-NOx kudlule kwi-92%. I-limestone slurry, eyayibangele ukukala kunye nokuvaleka ngaphambili, igcinwe kuxinano olufanelekileyo, isusa ukugcinwa okungacwangciswanga kwaye yanciphisa ixesha lokungasebenzi ngama-20%. Olu phuculo aluzange luzise isityalo kuphela ukuba sihambelane nemigangatho yokusingqongileyo kodwa lunciphise neendleko zokusebenza nge-15%.
Kutheni iiMeter zoBunzima obuPhakathi zibalulekile
Okwahlula iimitha zoxinano oluphakathi kwezinye izisombululo zokubeka esweni kukuguquguquka kwazo kunye nokuguquguquka kwazo. Azipheleli nje ekutsaleni i-nitration; usetyenziso lwazo lufikelela nakweyiphi na inkqubo yemizi-mveliso efuna ulawulo oluchanekileyo lolwelo. Kwimeko yezityalo zamandla, oku kuquka iinkqubo zokususa i-sulfurization, unyango lwamanzi amdaka, kunye nemisebenzi yokuxuba amafutha. Ukukwazi kwazo ukubonelela ngedatha yexesha langempela, echanekileyo, nesebenzayo kuzenza zibe lilitye lesiseko lokuphucula inkqubo yanamhlanje.
Ngokusebenzisa ezi zixhobo, izitishi zamandla zinokufikelela kwinqanaba lolawulo lwenkqubo elalingafumaneki ngaphambili. Iingenelo zidlula ukuthobela kunye nokusebenza kakuhle; ziquka nokuphuculwa kwexesha elide lezixhobo, ukunciphisa iindleko zokugcinwa, kunye nokuqina okuphuculweyo. Kwabasebenzi abaxabisa zombini ukusebenza kunye noxanduva lokusingqongileyo, iimitha zoxinano olungaphakathi azilotyalo-mali nje kuphela—ziyimfuneko.
Isiphelo
Ukwamkelwa kweemitha zoxinano olungaphakathi kwiinkqubo zokukhupha umoya kubonisa indlela ubuchwepheshe obuphucukileyo obunokuguqula ngayo iinkqubo zoshishino. Ngokujongana nemingeni efana nokungaguquguquki kwe-reagent, ukutyibilika kwe-ammonia, kunye nokuzisebenzela ngokuzenzekelayo, ezi zixhobo zivumela izityalo zamandla ukuba zisebenze ngokufanelekileyo, ngokuzinzileyo, nangokunenzuzo. Irekhodi lazo eliqinisekisiweyo kwizicelo zehlabathi lokwenyani ligxininisa ixabiso lazo njengesixhobo esibalulekileyo ekulweni nokukhutshwa kwe-NOx. Ukuba ujonge ukuphakamisa imisebenzi yakho yokukhupha umoya, akukho xesha lingcono lokuhlola amandla okulinganisa uxinano olungaphakathi.
