Cov roj biogas muaj nqis zuj zus thaum cov roj fossil siv tas. Nws muaj cov khoom siv hydrogen sulfide (H₂S) uas ua rau xeb heev, uas ua rau cov khoom siv hlau xws li cov kav dej, cov qhov dej thiab cov khoom siv hlawv. Qhov ua rau muaj kev puas tsuaj rau lub zog thiab lub neej ntawm cov khoom siv.
Kev tshem tawm cov sulfur yog kev ua haujlwm uas tsis ua rau ib puag ncig puas tsuaj los ntawm kev txo cov pa roj sulfur dioxide, uas yog qhov ua rau muaj nag los ntawm cov kua qaub thiab cov pa phem. Kev tshem tawm cov sulfur yog ib qho kev ntsuas tsim nyog los ua kom tau raws li cov cai ib puag ncig nruj. Tsis tas li ntawd, nws txhim kho kev ua haujlwm ntawm kev hlawv kom huv dua, txhim kho kev tsim hluav taws xob thiab txo cov nqi ua haujlwm tib lub sijhawm.
Cov teeb meem hauv Kev Tsim Kho Biogas Ib Txwm Muaj
Muaj tej yam tseem ceeb uas ua rau cov biogas desulfurization tsis muaj zog xws li kev ntsuas qeeb, kev ua yuam kev ntawm tes, kev siv zog ua haujlwm ntau thiab kev txhawj xeeb txog kev nyab xeeb. Cia peb tham txog cov teeb meem saum toj no ib qho zuj zus tam sim no.
Kev kuaj tes ntawm lub sijhawm yog txoj hauv kev tseem ceeb los saib xyuas qhov ceev. Txawm li cas los xij, qhov ceev ntawm cov kua desulfurization yuav txawv thaum lub sijhawm sib txawv, uas ua rau muaj qhov tsis zoo tseem ceeb hauv kev ua kom sai lossis qeeb ntawm cov tshuaj desulfurization. Kev ntsuas ncua sijhawm ua rau cov neeg siv kawg tsis tuaj yeem nrhiav teeb meem thiab daws lawv raws sijhawm.
Kev ua haujlwm tes hauv kev kuaj thiab xa mus ua rau muaj qhov yuam kev. Piv txwv li, cov kua desulfurization feem ntau yuav ua rau muaj kev cuam tshuam nrog huab cua lossis muaj kuab paug, ua rau tsis raug hauv kev ntsuas. Ntxiv mus, kev nyeem tsis tau zoo yuav tshwm sim los ntawm lub kaum sab xis ntawm tus neeg saib, cov npuas hauv cov kua lossis kev hloov pauv ib puag ncig.
Kev kuaj thiab ntsuas tes ua haujlwm ntau ua rau muaj kev ua haujlwm ntau thiab tus nqi ua haujlwm siab, tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag desulfurization loj uas muaj ntau qhov chaw ntsuas. Thiab cov neeg ua haujlwm raug rau cov tshuaj lom neeg los ntawm cov kua desulfurization feem ntau ntsib teeb meem noj qab haus huv mus rau qee qib. Ntxiv mus, kev ua haujlwm tes ntau zaus hauv ib puag ncig ntawm cov biogas flammable yuav ua rau muaj hluav taws xob static thiab txawm tias hluav taws xob.
Cov Haujlwm ntawm Cov Khoom Siv Ntsuas Qhov Ceev
Hauv cov txheej txheem biogas desulfurization, cov ntsuas ceev online ua lub luag haujlwm tseem ceeb los ntawm kev txhim kho kev ua haujlwm zoo, kev nyab xeeb, thiab kev ua raws li ib puag ncig. Nov yog lawv cov ntawv thov tseem ceeb:
- Kev Saib Xyuas Kev Ua Kua Desulfurization
Hauv kev siv cov roj biogas uas ntub dej desulfurization, cov kua alkaline siv los tshem tawm cov hydrogen sulfide (H₂S) los ntawm kev sib cuag nrog cov kua desulfurization. Qhov concentration ntawm cov kua desulfurization sib raug zoo nrog nws qhov ceev, uas cov ntsuas ceev online tuaj yeem saib xyuas tau tiag tiag. Qhov no ua rau cov neeg teb xov tooj tswj tau qhov concentration ntawm cov kua zoo tshaj plaws, ua kom muaj kev tshem tawm H₂S zoo thiab kev ruaj khov ntawm cov txheej txheem. - Kev Txhim Kho Cov Kev Mob Tshwm Sim
Qhov ceev ntawm cov kua desulfurization hloov pauv thaum cov tshuaj reactants raug noj thiab cov khoom tsim thaum lub sijhawm tshuaj lom neeg. Los ntawm kev taug qab cov kev hloov pauv ceev no, cov ntsuas ceev online muab kev nkag siab txog kev nce qib thiab kev ua haujlwm ntawm cov tshuaj. Cov neeg ua haujlwm tuaj yeem kho cov kev ntsuas xws li kub, siab, thiab cov khoom sib xyaw kom txhim kho qhov nrawm ntawm desulfurization thiab txhim kho kev ua haujlwm tshem tawm sulfur. - Kev Tswj Xyuas Kev Kho Dej Pov Tseg
Cov txheej txheem desulfurization tsim cov dej khib nyiab uas muaj cov sulfates thiab lwm yam pa phem ntau. Los ntawm kev saib xyuas qhov ceev ntawm cov dej khib nyiab no, cov ntsuas ceev online pab txiav txim siab qhov ntau ntawm cov pa phem, ua rau muaj kev hloov kho kom raug hauv cov tswv yim kho dej khib nyiab kom ua tau raws li cov qauv ib puag ncig. - Tiv Thaiv Kev Thaiv Khoom Siv
Hauv cov txheej txheem zoo li atmospheric ntub oxidative desulfurization (piv txwv li, siv cov tshuaj sodium carbonate), cov kua dej tsis txaus lossis cov tshuaj tsuag tsis raug tuaj yeem ua rau muaj kev thaiv hauv cov pej thuam desulfurization. Cov ntsuas ceev online muab kev ceeb toom thaum ntxov los ntawm kev ntes cov kev hloov pauv ceev, pab tiv thaiv cov teeb meem xws li fouling lossis clogging ntawm cov txaj ntim. - Kev Ua Kom Lub System Ruaj Khoov thiab Muaj Kev Nyab Xeeb
Nrog rau cov lus teb tam sim ntawd rau cov ntsuas qhov ceev tseem ceeb, cov ntsuas no txhawb nqa kev ua haujlwm ruaj khov ntawm lub cev, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv lossis kev cuam tshuam ntawm cov txheej txheem. Tsis tas li ntawd, lawv txo qis tib neeg kev raug rau cov khoom phom sij los ntawm kev tshem tawm qhov xav tau kev kuaj tes ntau zaus hauv cov chaw muaj kev phom sij.
Cov Khoom Pom Zoo & Cov Txiaj Ntsig Sib Xws
Tus lej 1 Tuning Fork Density Meter
Nws zoo tagnrho rau cov slurries zoo li cov uas pom nyob rau hauv cov txheej txheem desulfurization ntub. Lawv muab kev ntsuas qhov ceev tas mus li, thiab muaj qhov yooj yim rau kev teeb tsa ncaj qha. Lawv cov qauv tsim muaj zog txo cov nqi kho thiab ua rau lub kaw lus ntseeg tau ntau dua, ua rau lawv haum rau kev siv biogas hauv kev lag luam.
Lub Twj Tso Kua Roj Ntsuas Qhov Ceev
Tus lej 2 Ultrasonic Density Meter
Lub 'meter' no siv tau nrog ntau yam kev siv, suav nrog kev tsim tshuaj lom neeg. Lawv txoj kev tsim qauv ruaj khov, kev sib haum xeeb nrog cov kua dej corrosive, thiab cov ntaub ntawv digital tso tawm ua rau lawv muaj txiaj ntsig zoo rau kev saib xyuas cov txheej txheem biogas desulfurization.
Tus lej 3 Coriolis Flow Meter
Txawm hais tias feem ntau yog Coriolis flow meters, lawv kuj tseem tuaj yeem ntsuas qhov ceev nrog qhov tseeb siab hauv cov txheej txheem uas muaj cov kua nrog ntau qhov sib txawv. Lawv txhim khu kev qha rau biogas desulfurization qhov twg kev tswj hwm qhov tseeb ntawm cov tshuaj lom neeg yog qhov tseem ceeb.
Cov kev daws teeb meem rau biogas desulfurization yuav tsum hais txog lub luag haujlwm tseem ceeb ntawm kev siv tshuab hauv kev lag luam thiab kev tswj hwm qhov tseeb hauv kev ua kom zoo dua cov txheej txheem. Los ntawm kev siv cov cuab yeej saib xyuas lub sijhawm tiag tiag, xws li cov ntsuas qhov ceev hauv kab, kev lag luam tuaj yeem tswj hwm cov kua desulfurization kom zoo kom ntseeg tau tias muaj kev ua haujlwm siab thiab kev ruaj khov ntawm lub kaw lus. Qhov no tsis yog tsuas yog tiv thaiv cov khoom siv xeb thiab thaiv xwb tab sis kuj txo cov nqi ua haujlwm thiab txhim kho kev ua raws li ib puag ncig los ntawm kev txo qis cov pa phem xws li hydrogen sulfide.
Ntxiv mus, kev siv tshuab ua kom cov txheej txheem desulfurization txo qis kev siv zog ua haujlwm, ua rau muaj kev nyab xeeb ntau dua, thiab ua kom muaj kev ua haujlwm tas mus li thiab txhim khu kev qha. Kev tswj hwm qhov tseeb ntawm cov kua desulfurization ua rau muaj kev kho kom zoo ntawm cov xwm txheej ua haujlwm, thaum kawg txhim kho kev siv hluav taws xob thiab qhov zoo ntawm biogas. Cov kev nce qib no sawv cev rau kev dhia mus rau pem hauv ntej hauv kev lag luam ruaj khov, ua raws li lub hom phiaj niaj hnub no ntawm lub zog thiab kev saib xyuas ib puag ncig.
