1. Cov txiaj ntsig tseem ceeb rau cov xwm txheej ntawm Sludge Pipe
Doppler ultrasonic flowmeterssawv tawm hauv cov ntawv thov sludge yeeb nkab feem ntau yog vim peb lub zog. Ua ntej, lawv cov qauv tsim tsis-intrusive clamp-on txhais tau tias tsis muaj cov khoom txuas mus rau hauv cov kav dej, zam kev txhaws los ntawm sludge cov khoom seem (xws li grit, organic flocs, lossis fiber) thiab txo qhov xav tau kev rhuav tshem thiab ntxuav ntau zaus. Qhov thib ob, lawv hloov kho zoo rau sludge cov khoom sib txawv - tsis zoo li cov ntsuas hluav taws xob uas ua tsis tiav nrog cov sludge qis-conductivity, lossis turbine meters rhiab rau turbulence, cov flowmeters no tsuas yog xav tau cov khoom sib piv txaus hauv sludge kom tswj tau qhov tseeb, txawm tias rau cov hom viscosity siab. Qhov thib peb, lawv cov transducers sab nraud yog ua los ntawm cov ntaub ntawv tiv taus corrosion (piv txwv li, PTFE, ceramic), uas tuaj yeem tiv taus acidic lossis alkaline industrial sludge, ntev lawv lub neej kev pabcuam mus rau 8-10 xyoo, ntev dua li cov ntsuas intrusive.
2. Cov Ntsiab Lus Tseem Ceeb rau Kev Siv Ua Haujlwm
Lawv siv dav hauv peb qhov chaw tseem ceeb uas cuam tshuam nrog cov sludge. Hauv cov chaw kho dej khib nyiab hauv nroog, lawv saib xyuas cov dej ntws ntawm cov sludge hla cov theem tseem ceeb: thaum lub sijhawm tuab, lawv pab ua kom zoo dua cov tshuaj flocculant los ntawm kev taug qab cov dej ntws ntawm cov sludge raw; hauv kev zom zaub mov, lawv tswj cov khoom siv digester anaerobic los ntawm kev ntsuas cov dej ntws ntawm cov sludge uas zom (txawm tias muaj cov npuas biogas); hauv kev tshem dej tawm, lawv kho cov kev ntsuas los ntawm kev saib xyuas cov sludge nkag mus rau hauv cov tshuab lim dej - piv txwv li, lub Hoobkas Berlin tau txhim kho qhov tseeb ntawm kev ntsuas mus rau ± 2% thiab txiav kev saib xyuas los ntawm 70% tom qab kev saws txais. Rau cov sludge kev lag luam (piv txwv li, cov fiber ntau pulp mill sludge lossis cov roj petrochemical sludge), lawv daws cov teeb meem clogging uas ua rau muaj teeb meem rau cov ntsuas ib txwm muaj, ua kom muaj kev ua haujlwm tas mus li. Lawv kuj txhawb nqa kev siv sludge rov qab, xws li hauv cov haujlwm sludge-rau-biogas, qhov twg lawv ntsuas cov dej ntws ntawm cov sludge zom kom zoo dua qhov sib xyaw ntawm cov sludge thiab lwm yam khoom siv, ua rau cov biogas muaj txiaj ntsig zoo dua.
3. Cov Lus Qhia Tseem Ceeb rau Kev Teeb Tsa
Kev teeb tsa kom raug yog qhov tseem ceeb rau kev ua kom ntsuas tau qhov tseeb, thiab yuav tsum tau sau tseg peb lub ntsiab lus. Ua ntej, xaiv ib ntu yeeb nkab ncaj: qhov ntev ntawm sab saud yuav tsum yog tsawg kawg 10 npaug ntawm txoj kab uas hla ntawm yeeb nkab, thiab qhov ntev ntawm sab hauv qab tsawg kawg 5 npaug, kom tsis txhob muaj kev cuam tshuam ntawm cov dej ntws los ntawm lub luj tshib, lub qhov dej, lossis lub twj tso kua mis uas cuam tshuam rau kev ntseeg tau ntawm cov ntaub ntawv. Qhov thib ob, tso cov transducers kom raug: rau cov yeeb nkab kab rov tav, teeb tsa lawv 45 ° - 90 ° saum toj ntawm hauv qab yeeb nkab - qhov no zam kev muaj cua (uas ua rau muaj kev cuam tshuam tsis raug) thiab cov av noo sib sau ua ke (uas thaiv kev xa cov teeb liab); rau cov yeeb nkab ntsug, xyuas kom meej tias cov av noo ntws mus rau sab saud kom khaws cov khoom faib sib npaug. Qhov thib peb, siv cov neeg sawv cev sib txuas tsim nyog: xaiv cov hom kub siab thiab cov roj-resistant kom ntseeg tau tias muaj kev sib cuag nruj ntawm cov transducers thiab phab ntsa yeeb nkab, tshwj xeeb tshaj yog rau cov yeeb nkab thauj cov av noo kub siab.
Kev Txheeb Xyuas
Doppler ultrasonic flowmetersLawv zoo siv rau cov yeeb nkab sludge, nrog rau qhov zoo ntawm kev tiv thaiv kev txhaws, kev hloov pauv tau zoo, thiab kev tiv thaiv xeb. Lawv ua lub luag haujlwm tseem ceeb hauv kev kho cov dej khib nyiab hauv nroog, kev tswj cov sludge hauv kev lag luam, thiab kev siv sludge rov qab, thaum kev teeb tsa kom zoo (tsom mus rau kev xaiv seem yeeb nkab, kev tso transducer, thiab kev siv tus neeg sawv cev sib txuas) ua kom lawv ua haujlwm ruaj khov thiab raug. Cov yam ntxwv no ua rau lawv yog cov kev daws teeb meem txhim khu kev qha rau kev daws teeb meem ntawm kev ntsuas cov dej ntws sludge.
