Flue gas desulfurization hauv refinery hnyav hauv kev txo cov kev pheej hmoo ntawm cov kua qaub los nag thiab txhim kho huab cua zoo. Rau lub hom phiaj ntawm kev txhim kho kev ua tau zoo thiab kev txuag nqi, tus nqi ntawm desulfurizer yuav tsum tau kho raws li cov qauv nruj. Kev lig kev cai desulfurization cia siab rau kev hloov kho ntawm phau ntawv los yog qhov sib piv ruaj khov, uas txhais tau hais tias tsis muaj qhov yuam kev thiab cov khoom pov tseg.
Daim ntawv thov ntawm inline density meters yog ib qho kev lees paub ntawm kev tswj xyuas meej ntawm desulfurizer hauv lub sijhawm tiag tiag, txo cov nqi ua haujlwm, kev siv tshuaj lom neeg thiab kev noj ib puag ncig ntxiv.
Kev sib tw hauv Refinery Flue Gas Desulfurization
Thawj qhov kev sib tw hauv refinery flue roj desulfurization yog nyob rau hauv kev tswj kom meej txog qhov ntau npaum li cas ntawm desulfurizers. Cov desulfurizers xws li txiv qaub, sodium hydroxide los yog lwm yam reacts nrog sulfur compounds ntawm cov roj flue thiab tom qab ntawd tsim cov khoom lag luam. Qhov ntau npaum ntawm desulfurizer nyob ntawm qhov tshwj xeeb ntawm cov sulfur compounds hauv emissions.
Txawm li cas los xij, cov roj flue hauv kev hloov pauv hloov ua rau nws nyuaj rau kev siv tshuab los txiav txim siab qhov concentration ntawm desulfurizers meej. Tus nqi ntawm desulfurizer yuav ntau dhau lossis tsis txaus, thiab ob qhov xwm txheej no ua rau cov txiaj ntsig zoo sib xws hauv cov txheej txheem ntawm desulfurization. Cia peb dhia mus rau hauv ob qho xwm txheej no kom ntxaws.
Ntau dhau desulfurizer nkag mus rau hauv cov tshuaj sulfur ua rau tus nqi nce, tshwj xeeb tshaj yog nyob rau hauv kev ua haujlwm loj. Tsis tas li ntawd, ntau dhau desulfurization ua rau muaj ntau dua cov kua qaub kua qaub thiab cov dej khib nyiab superfluous, uas ua rau cov nqi ntxiv ntawm kev kho dej khib nyiab. Qhov kawg tab sis tsis yog qhov tsawg tshaj plaws, cov desulfurizers ntau dhau ua rau muaj kev pheej hmoo ntawm kev xeb hauv cov kav dej thiab cov khoom siv, tom qab ntawd cov kua qaub dhau yuav ua rau ntau zaus ntawm kev saib xyuas thiab hloov.
Ntawm qhov tsis sib xws, cov desulfurizers tsis txaus txo qhov ua tau zoo ntawm cov txheej txheem desulfurization, yog li cov sulfur tebchaw tseem nyob hauv cov roj flue ntawm qee qhov concentration. Nws hloov tawm tias ua tsis tau raws li cov qauv emission, ua rau muaj kev cuam tshuam tsis zoo rau ob qho tib si kev nyab xeeb thiab kev ua raws li cov cai ntawm ib puag ncig.
Qhov zoo ntawm Inline Density Meters
Txhawm rau ua kom muaj txiaj ntsig ntawm kev ua haujlwm rov ua dua thiab txo qis qhov tsis tsim nyog ntawm phau ntawv yuam kev, inline density meters yog ib qho kev xaiv zoo tshaj plaws hauv kev ua lag luam. Ua raws li cov txiaj ntsig pom tseeb yog txhua qhov laj thawj los xaiv qhov tseeb online density meters.
Kev Tswj Xyuas Ntau Yam Ntawm Cov Desulfurizers
Lub desulfurizer reacts nrog sulfur compounds nyob rau hauv cov txheej txheem desulfurization ua raws li cov kev cai nruj. Qhov ceev ntawm desulfurization kua hloov raws li qhov txo qis ntawm sulfur compounds concentration hauv ib txwm.
Cov kev hloov pauv ceev tau saib xyuas tsis tu ncua thiab xa mus rau cov ntaub ntawv sau cov kab ke hauv cov teeb liab hluav taws xob, uas ua rau lub sijhawm hloov kho tau los ntawm kev tswj xyuas qhov tshem tawm ntawm cov sulfur compounds. Qhov ntse hauv online density meter muaj peev xwm nce lossis txo cov desulfurizers ntxiv raws li qhov ceev tau, tiv thaiv kev siv ntau dhau lossis tsis txaus.
Txhim kho cov tshuaj tiv thaiv zoo thiab txo cov pov tseg
Los ntawm kev tswj hwm qhov ntau npaum li cas ntawm tus neeg sawv cev desulfurizing, qhov ntsuas qhov ntom ntom kom ntseeg tau tias cov txheej txheem desulfurization ua haujlwm tau zoo npaum li qhov ua tau, thaum txo qis cov tshuaj tsis tsim nyog. Qhov no, nyob rau hauv lem, txo cov nqi khiav hauj lwm.
Txo cov kev cuam tshuam ntawm ib puag ncig
Lub ntsuas ntsuas ntse ntse txo cov nqi ua haujlwm thiab cov tshuaj phem tso tawm rau saum huab cua. Los ntawm kev txo cov load ntawm cov dej khib nyiab, cov tshuaj lom neeg hauv cov dej khib nyiab tau txo qis heev. Nyob rau tib lub sijhawm, kev pheej hmoo ntawm huab cua muaj kuab paug qis dua, ib yam nkaus.
Qhov zoo tshaj plaws adaptability rau Kev Hloov Kev Ua Haujlwm
Qhov sib xyaw ntawm refinery flue gas yog complex, thiab kub thiab siab tej yam kev mob fluctuate ho. Insertion-type online density metres feem ntau yog tsim los tiv thaiv qhov kub thiab txias, kub siab, thiab corrosive ib puag ncig, kom ntseeg tau tias kev ua haujlwm ruaj khov thiab raug sau cov ntaub ntawv raws li cov xwm txheej nyuaj.
Daim ntawv thov
