Desulfurization npauj npaim valve yog ib qho corrosion-resistant thiab hnav-resistant npauj npaim valve tsim tshwj xeeb rau desulfurization thiab denitrification engineering. Nws tag nrho txiav txim siab qhov corrosion thiab hnav ntawm desulfurization slurry ntawm lub valve, kom ntseeg tau tias lub valve phaj hauv ob sab phlu yog tib yam khoom uas tuaj yeem cuam tshuam nrog cov slurry, thaum lwm cov khoom tsis corroded los ntawm limestone (los yog txiv qaub muab tshuaj txhuam) slurry. Yog li ntawd, lub valve lub cev thiab qia tsis tas yuav siv cov khoom siv kim kim (2205), txuag nqi ntau. Lub rooj zaum tsim tshwj xeeb ntawm desulfurization npauj npaim valve tag cais lub cev lub cev los ntawm cov kua nruab nrab. Piv nrog rau lwm yam li qub, nws muaj txoj hauv kev zoo dua ntawm kev ruaj ntseg ntawm lub rooj zaum, kev hloov ceev ceev ntawm lub rooj zaum ntawm qhov chaw, xoom xaim ntawm lub valve, thiab kev sib txhuam qis. Npauj npaim valve phaj yog ua los ntawm cov khoom siv ua haujlwm siab (2205), tiv taus corrosion thiab hnav ntawm slurry.
Txoj cai ntawm desulfurization npauj npaim valve
Desulfurization yog hais txog kev siv calcium raws li txoj hauv kev los kho cov sulfur hauv cov thee rau hauv cov khoom kom tiv thaiv kev tsim ntawm SO2 thaum lub sij hawm combustion. Tam sim no, txoj kev desulfurization feem ntau tuaj yeem muab faib ua peb pawg: ua ntej combustion desulfurization, thaum combustion desulfurization, thiab tom qab combustion desulfurization. Lub desulfurization npauj npaim valve yuav tsum ua kom tau raws li qhov yuav tsum tau muaj ntawm corrosion, hnav txaus tus nqi, kub, thiab lwm yam. Ntau cov ntxhia roj muaj cov sulfur, tshwj xeeb tshaj yog cov thee, uas ua rau muaj ntau ntawm SO2 tom qab combustion, ua rau huab cua phem heev. Txhawm rau tswj cov pa phem, txoj hauv kev zoo yog flue gas desulfurization. Nrog rau Tuam Tshoj, cov txiv qaub (limestone) ntub desulfurization tshuab yog tam sim no dav siv nyob rau hauv lub ntiaj teb no. Cov txheej txheem no suav nrog ntau yam corrosive media thiab muaj cov ntaub ntawv granular, uas ua rau muaj zog corrosion thiab hnav rau cov khoom siv. Yog li ntawd, muaj cov kev cai tshwj xeeb rau cov khoom siv thiab cov qauv ntawm lub valve.
