Hauv kev lag luam tshuaj, khoom noj, tshuaj, thiab lub zog rov qab, evaporators, ua cov cuab yeej tseem ceeb rau kev ua tiav cov cua sov thiab vaporization ntawm cov kua xov xwm thiab cov khoom sib cais, feem ntau ntsib ntau yam teeb meem rau kev ua haujlwm ruaj khov, suav nrog kev ntsuas, kev xeb, kev puas tsuaj ntawm cov cua sov- cov ntaub ntawv rhiab heev, kev siv hluav taws xob ntau, thiab kev hloov pauv tsis txaus. Kev ntsuas kev txhim kho ib leeg tsis txaus los npog cov kev ua haujlwm nyuaj; xav tau ib qho kev daws teeb meem, tsim lub voj kaw los ntawm kev tsim kho kom zoo thiab kev tswj xyuas kev ua haujlwm rau kev tswj xyuas, kom ntseeg tau tias cov khoom siv tau zoo, txhim khu kev qha, thiab kev lag luam.
Hais txog scaling thiab clogging, qhov kev daws teeb meem ua ntej tsom mus rau cov qauv tsim thiab cov khoom sib txuam. Txhawm rau kom yooj yim crystallizing lossis siab - cov ntaub ntawv viscosity, yuam cov evaporators ua ke nrog cov dej ntws dav thiab tus kheej - cov qauv ntxuav tuaj yeem txo qhov tshwm sim ntawm cov khoom khaws cia. Hais txog ntawm cov ntaub ntawv, kev tiv thaiv -scaling los yog low deg zog coatings tuaj yeem inhibit thawj crystal nucleation thiab txuas ntxiv mus txuas ntxiv ua haujlwm. Thaum lub sijhawm ua haujlwm, kev saib xyuas online thiab lub sijhawm rov qab ua haujlwm tau qhia, dynamically teem sijhawm tu raws li kev hloov pauv ntawm qhov sib txawv ntawm qhov sib txawv thiab kev siv evaporation los tiv thaiv cov nplai ntau dhau los ntawm kev cuam tshuam rau kev hloov hluav taws xob.
Rau cov xov xwm corrosive, qhov kev daws teeb meem hais txog ob qho tib si xaiv qhov tseeb ntawm corrosion- cov ntaub ntawv tiv taus thiab kev tiv thaiv nto. Rau ib puag ncig uas muaj cov kua qaub muaj zog, muaj zog alkalis, lossis chloride ions, titanium, nickel-raws li alloys, lossis tshwj xeeb stainless hlau yog nyiam, ua ke nrog cathodic tiv thaiv lossis tiv thaiv- coatings los txhim kho kev ua haujlwm ntev. Nyob rau sab txheej txheem, kho pH, kub, thiab redox muaj peev xwm txo tau cov tshuaj corrosion ntawm cov cuab yeej los ntawm nruab nrab.
Qhov kev sib tw hauv kev tuav cov cua sov- cov ntaub ntawv rhiab yog nyob rau hauv kev tswj cov cua kub thiab lub sij hawm. Cov kev daws teeb meem suav nrog kev siv lub tshuab nqus tsev qis- qhov kub thiab txias evaporation kom txo qhov kub ntawm qhov kub, xaiv cov khib nyiab los yog phaj evaporators nrog lub sij hawm nyob luv luv, thiab ua kom zoo dua cov cua sov saum npoo kom txo qhov kub sib txawv hauv zos. Multi-theem flash evaporation thiab gradient cua sov tswv yim kuj tseem tuaj yeem zam cov khoom tawg lossis deactivation tshwm sim los ntawm ib qho - theem siab kub.
Hais txog kev tswj hwm kev siv hluav taws xob, cov kev daws teeb meem tawm tswv yim rau kev siv hluav taws xob sib txuas thiab kev sib txuas ua kom zoo. Multi-effect evaporation siv cov pa theem nrab los ntawm cov nyhuv ua ntej los ua qhov cua sov rau cov nyhuv tom ntej, txo cov pa noj nyob hauv; ua ke nrog cov twj siv hluav taws xob los yog cov khoom siv hluav taws xob pov tseg, cov khoom siv hluav taws xob tsawg -kub khib nyiab tau hloov mus ua lub zog siv tau, txhim kho tag nrho cov thermal efficiency. Cov kev tswj xyuas ntse kho cua sov lub zog thiab pub tus nqi hauv lub sijhawm raws li kev hloov pauv, tswj cov evaporator nyob rau hauv nws qhov zoo tshaj plaws tshav kub hloov coefficient.
Kev saib xyuas thiab kev tswj xyuas cov kev daws teeb meem hais txog kev saib xyuas thiab cov ntaub ntawv kwv yees - tsav kev txiav txim siab - ua. Los ntawm kev xa cov sensors los saib xyuas qhov kub thiab txias, siab, ntws tus nqi, thiab ntsuas, thiab tsim cov qauv kev soj ntsuam cov qauv, kev hloov pauv ntawm kev teem sijhawm tu mus rau qhov xwm txheej-raws li kev saib xyuas tuaj yeem ua tiav, txo qis kev poob qis thiab kev siv lub neej ntev.
Hauv cov ntsiab lus, cov evaporator cov kev daws teeb meem yuav tsum tau ua ke nrog cov qauv kev tsim kho tshiab, kev xaiv cov khoom siv, kev ua kom zoo dua qub, kev txhim kho kev siv hluav taws xob, thiab kev ua haujlwm ntse thiab kev saib xyuas kom daws tau cov kev ua haujlwm tsis zoo los ntawm ntau qhov ntev, muab kev ntseeg siab, ua tau zoo, thiab kev txhawb nqa evaporation rau ntau yam lag luam.
