Nyob rau hauv xyoo tas los no, tib neeg txoj kev vam khom rau thaj chaw ecological tau nce ntau. Nrog rau kev loj hlob sai ntawm cov ntaub ntawv thiab AI era, kev tiv thaiv ib puag ncig tau dhau los ua lub ntsiab lus kub, nquag hais tsis yog hauv kev tsim kho kev lag luam nkaus xwb tab sis kuj tseem nyob hauv lub neej niaj hnub. Yog li ntawd, kev txhim kho kev tiv thaiv ib puag ncig yog qhov tseem ceeb rau kev tsim kho kev lag luam, uas muaj kev cuam tshuam rau ib puag ncig.
Hauv thaj tsam ntawm xoom- tso tawm ntawm siab- dej qab ntsev muaj cov dej khib nyiab, kev siv cov khoom siv ntsev yuav dhau los ua qhov tseem ceeb rau kev tswj hwm ib puag ncig yav tom ntej, txo qis kev pov tseg pov tseg thiab txhim kho cov peev txheej rov qab thiab siv tus nqi, uas muaj txiaj ntsig zoo rau kev txhim kho tag nrho cov kev tiv thaiv ib puag ncig. Nyob rau hauv xoom- tso tawm cov txheej txheem ntawm high- salinity industrial wastewater, kev txhim kho tus nqi ntxiv ntawm cov pa pa thiab ua kom muaj zog siv hluav taws xob yog qhov tseem ceeb rau kev ntsuas xoom- tso tawm muaj peev xwm. MVR (Mechanical Vapor Recompression) thev naus laus zis tuaj yeem daws cov teeb meem ua tau zoo hauv xoom- tso tawm siab - dej qab ntsev.
1. MVR Mechanical Vapor Recompression Technology
MVR mechanical vapor recompression thev naus laus zis feem ntau yog siv rau hauv cov haujlwm tshwj xeeb hauv qab no. Qhov thib ib yog seawater desalination. Tam sim no, rov qab osmosis thiab distillation yog feem ntau siv txoj kev rau seawater desalination hauv kuv lub teb chaws. Txoj kev Distillation feem ntau poob rau hauv peb pawg: ntau- cuam tshuam evaporation (MVR), cryogenic freezing, thiab vapor compression distillation. Sib piv cov thev naus laus zis no hauv kev siv cov tswv yim, MVR thev naus laus zis muab kev txuag hluav taws xob tseem ceeb tshaj plaws. Yog li ntawd, thaum xaiv lub compressor rau ib qho MVR system, siab - compressor kev ua tau zoo nrog ib tug kuj tsawg compression piv yuav tsum tau xaiv.
Hauv kev kho dej khib nyiab hauv kev lag luam, ntau qhov siab - cov dej qab ntsev feem ntau muaj sodium chloride thiab sodium sulfate. Ntau lub tuam txhab hauv Suav teb xaiv ntau-txhim kho evaporation tshuab los kho ntsev, tab sis hauv kev ua haujlwm tiag tiag, qhov siv hluav taws xob siv hluav taws xob tsuas yog nyob ib ncig ntawm 80%, uas ua rau muaj hluav taws xob tseem ceeb. Nyob rau hauv sib piv, cov teb chaws tsim thiab cheeb tsam txawv teb chaws feem ntau siv MVR tshuab rau ntsev ntau lawm. Nyob rau yav tom ntej zero-emission processes, qhia MVR thev naus laus zis rau hauv kev lag luam ntsev tuaj yeem daws tau qhov teeb meem ntawm cov nqi tag nrho, txo cov nqi thiab cov nqi siv. Tsis tas li ntawd, nws txhim kho qhov zoo thiab kev ua tau zoo ntawm ntau hom ntsev ntsev. Dhau li ntawm cov kev siv tswv yim no, MVR thev naus laus zis kuj tseem tau siv dav hauv cov khoom lag luam emulsion, papermaking, thiab distillation, qhia txog kev cog lus rau yav tom ntej.
2. Yam ntxwv ntawm MVR Technology nyob rau hauv siab -Salinity Wastewater Resource Siv
2.1 Qhov zoo ntawm MVR Technology piv nrog lwm cov thev naus laus zis
Raws li kev siv hauv kuv lub teb chaws, cov thev naus laus zis dav siv rau xoom- tso tawm siab- cov dej qab ntsev feem ntau suav nrog RO rov qab osmosis membrane dual-membrane txoj kev thiab EDR thev naus laus zis. Cov khoom tseem ceeb yog nanoscale rov qab osmosis membrane. Cov thev naus laus zis no muaj txiaj ntsig zoo hauv kev sib cais thiab khaws cov hlau hnyav ions thiab ntau cov organic tebchaw. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis thiab txhim kho qib kev tshawb fawb, MVR thev naus laus zis tau txhim kho tag nrho cov txiaj ntsig. Nws tsis tsuas yog xav tau qhov chaw tsawg dua tab sis kuj muaj cov qauv yooj yim dua thiab lub zog zoo heev -txuag nyhuv. Lub hauv paus ntsiab lus tseem ceeb yog siv lub tshuab compressor los ua kom qis - qhov kub thiab txias, ua kom nws cov enthalpy thiab ua kom tag nrho cov cua sov latent ntawm cov chav kom ua tau raws li qhov xav tau.
2.2 Cov yam ntxwv cuam tshuam rau MVR Technology Performance thiab lawv tuav
Cov khoom siv hauv MVR thev naus laus zis rau kev rov qab los thiab kev kho mob tsis zoo ntawm siab -cov dej qab ntsev dej feem ntau suav nrog cov hauv qab no: qhov ceev thiab lub zog, qhov taw tes melting, kub rhiab heev, hardness, thiab viscosity. Thawj qhov kub hloov pauv coefficient nyob ntawm qhov chaw nyob los ntawm evaporation. Nto nro feem ntau yog siv los txhawb cov kua deg contraction siab thiab yog tus nqi thaum vapor-kua sib cais. Tsis tas li ntawd, rau cov ntaub ntawv uas muaj cov ntsiab lus kub kub heev, ib qho - cuam tshuam evaporation tuaj yeem siv los txo qhov kub ntawm tag nrho hauv qhov tsis zoo, txuag cov nqi khiav haujlwm.
Hauv qhov chaw ua haujlwm tiag tiag, thawj zaug yuav tsum tau them nyiaj rau kev hloov pauv ntawm cov khoom noj, thiab qhov thib ob rau kev hloov pauv hauv MVR compressor cov kev ua haujlwm. Lub compressor tus nqi ntws, qhov kub thiab txias -siab piv, efficiency, thiab lwm yam tsis muaj qhov tseem ceeb tshaj plaws, uas cuam tshuam ncaj qha rau tag nrho cov haujlwm ntawm chav tsev. Piv txwv li, nyob rau hauv kev kho mob ntawm ntau yam siab - dej qab ntsev dej khib nyiab, yog tias qhov kub ntawm qhov nkag yog qhov tsawg tab sis cov ntim tshwj xeeb nce siab, lub compressor tuaj yeem xa cov pa ntau, thiab qhov kub ntawm qhov nkag kuj tseem yuav nce ntxiv. Lub compressor qhov tseeb zaus, tus nqi ntws, thiab qhov kub thiab txias tuaj yeem teeb tsa.
Hauv cov khoom sib cais, nws yog ib qho tseem ceeb uas yuav tsum paub txog qhov nce evaporation ntawm siab - cov dej khib nyiab, uas ua rau kom cov pa nce ntxiv thiab ua rau cov roj nqa cov kua ntau ntau. Lub sij hawm raug rau qhov no tuaj yeem cuam tshuam qhov sib npaug ntawm qhov kub thiab txias. Nyob rau hauv MVR chav tshuab, lub flash evaporation ntawm theem nrab chav nce siab thaum lub sijhawm ruaj khov. Qhov tshwj xeeb ntim ntawm cov chav thib ob yog qhov loj, ua rau muaj kev nce ntxiv hauv cov khoom siv concentration thiab viscosity nro. Yog li ntawd, qhov sib piv ntawm txoj kab uas hla yuav tsum ua kom muaj roj txaus- sib cais kua, muab qhov sib cais txaus. Qhov siab thiab tus nqi kuj muaj kev cuam tshuam.
Tsis tas li ntawd, lub twj tso kua mis kuj muaj kev cuam tshuam. Raws li lub hauv paus fais fab unit, nws cov neeg kho tshuab ceev, qhov kev khiav hauj lwm txaus tus nqi, thiab qhov siab ncaj qha cuam tshuam thiab txwv tag nrho cov system. Kev siv zog yuav tsum tau ua kom txo tau qhov kev xau.
