Multi-effect evaporator yog dav siv nyob rau hauv evaporation thiab concentration ntawm dej los yog tov nyob rau hauv tshuaj, zaub mov, tshuaj kev lag luam, lub teeb kev lag luam thiab lwm yam lag luam. Ntxiv rau qhov no, nws tseem tuaj yeem siv dav hauv kev kho dej khib nyiab ntawm cov kev lag luam saum toj no. Nws muaj ntau yam zoo, xws li siab evaporation muaj peev xwm, txuag hluav taws xob thiab kev txo qis, thiab cov nqi khiav lag luam tsawg. Ntawm no yog cov kev ceev faj rau ntau yam cuam tshuam evaporator.
Thaum siv cov evaporator ntau yam, nws yuav tsum tau muab sau tseg tias yog tias qhov kub thiab txias tseem nce ntxiv, ua ntej xyuas seb lub tshuab nqus tsev puas yog tripped, tom qab ntawd xyuas seb lub condensate puas tsis tawm, thiab tom qab ntawd xyuas seb lub zog siab nce dheev thiab seb nws puas tuaj yeem ua tau. xau. Nres thiab tuav lub siab los txheeb xyuas qhov teeb meem. Nws lub tshuab cua sov sab saum toj yuav tsum tau nruab nrog kev nyab xeeb valve. Lub zog siab hauv lub tshuab cua sov sab saum toj yuav tsum tsis pub tshaj 0.01Mpa. Xyuas seb qhov kev ruaj ntseg valve feem ntau ua tsis tau. Tsis txhob careless. Txawm li cas los xij, lub qhov cub valve yuav tsum raug kaw thaum nres. Thaum lub evaporator circulating twj tso kua mis nres vim yog txhaum, lub chav yuav tsum raug kaw tam sim ntawd. Cov khoom no ua haujlwm los ntawm kev txuas ntau lub evaporators.
Qhov thib ob chav tsim los ntawm evaporation nyob rau hauv lub qub evaporator yog siv los ua cov cua kub ntawm cov evaporator tom kawg. Yog li ntawd, nws yog ib qho tsim nyog los rov siv lub zog hluav taws xob ntau zaus thiab txo qis kev siv hluav taws xob ntau. Multi-effect evaporator kuj tseem siv tau rau kev lag luam loj. Feem ntau, nws yuav tsum tau evaporate ntau cov dej, uas yuav tsum tau siv ntau lub zog los ua kom sov dej los ua kom muaj zog. Txhawm rau txo qhov kev siv cua sov chav, ntau qhov cuam tshuam evaporation tuaj yeem siv. Thaum lub sij hawm siv tiag tiag ntawm ntau cov nyhuv evaporator, xyuam xim rau lub siab ruaj khov thiab nquag soj ntsuam ntawm ntau cov nyhuv evaporator; Lub tshuab nqus tsev kawm ntawv thiab qhov kub thiab txias ua tau raws li qhov yuav tsum tau ua, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm kev ua haujlwm tsis zoo. Yog tias pom muaj qhov hloov pauv, nrhiav qhov laj thawj tam sim ntawd.
Kho qhov tso tawm valve ntawm ntau qhov cuam tshuam evaporator kom ua kom cov pa tawm tshwj xeeb raws li qhov yuav tsum tau ua thiab ntsuas nws tsis tu ncua. Thaum cov cuab yeej tsis ruaj khov, nws yuav tsum tau ntsuas ntau zaus; Raws li ib txwm muaj, yuav tsum tsis txhob muaj kev hloov pauv ntau dhau; Thaum qhov kub thiab txias tau nce sai, nws tam sim ntawd kaw lub tshuab nqus tsev vacuum los xyuas seb lub tshuab nqus tsev twj tso kua mis tawm mus. Yog tias muaj, kaw lub inlet valve ntawm lub tshuab nqus tsev twj. Yog tias tsis muaj qhov dhia, xyuas qhov xwm txheej thiab tos kom kub poob ua ntej pib. Tsis tas li ntawd, peb kuj yuav tsum tau kho lub feed valve kom stabilize cov kua theem nyob rau hauv nruab nrab ntawm daim iav. Lub tshuab nqus tsev twj tso kua mis, lub twj tso kua mis circulating thiab condensate twj tso kua mis ua haujlwm ib txwm.
Nws tseem yuav tsum tau muab sau tseg ntawm no tias yog tias qhov kub thiab txias tseem nce ntxiv, thawj zaug xyuas seb lub tshuab nqus tsev ntawm cov evaporator ntau qhov kev mus ncig, tom qab ntawd xyuas seb lub condensate tsis tau tso tawm, thiab tsis muaj teeb meem. Tshawb xyuas seb lub zog siab dheev nce siab, thiab seb nws puas tuaj yeem xau. Nws raug nquahu kom koj nres thiab tswj xyuas kom paub qhov teeb meem. Yog tias qhov kub thiab txias ntawm cov evaporator ntau qhov tshwm sim nce sai, kaw lub qhov cub tam sim ntawd kom pom tias nws mus ncig. Yog tias muaj, kaw lub qhov nqus dej. Yog tias tsis muaj qhov dhia, xyuas qhov xwm txheej thiab tos kom qhov kub thiab txias poob.
