Tswj Indicators ntawm Multi Effect Evaporators

Lub evaporator muaj ntau qhov sib txawv ntawm cov evaporators uas txuas nrog hauv cov koob, txhua theem hu ua kev ua haujlwm. Cov kev khiav hauj lwm siab thiab boiling point ntawm cov tshuaj nyob rau hauv lub post nyhuv ntawm multi-effect evaporator yeej ib txwm qis dua cov nyob rau hauv cov nyhuv ua ntej. Qhov thib ob chav evaporated los ntawm cov nyhuv ua ntej yog siv los ua cov nyhuv tom qab cua sov, thiab cov nyhuv tom qab rhaub yog lub condenser ntawm cov nyhuv ua ntej. Vim muaj ntau qhov rov qab siv dua ntawm cov chav thib ob, tag nrho cov evaporation tuaj yeem ncav cuag ob peb zaug ntawm kev noj cov chav tshiab. Ntau cov nyhuv evaporators muaj ntau yam cuam tshuam, thiab lub siab thiab kub ntawm txhua qhov cuam tshuam sib txawv, uas tseem cuam tshuam cov teeb meem ntawm cov khoom dhau ntawm cov teebmeem. Kev ua haujlwm nyuaj yog qhov siab, thiab kev teeb tsa ntawm cov khoom siv automation yuav txo cov haujlwm nyuaj. Txawm li cas los xij, tib neeg kev cuam tshuam tseem xav tau los txiav txim siab seb cov ntsuas ntsuas puas nyob hauv kev ua haujlwm ib txwm muaj.
1. Lub superheat ntawm lub tshav kub qhov cub. Ntau dhau superheat ntawm cov cua sov qhov cub tuaj yeem muaj kev cuam tshuam loj rau kev hloov pauv hluav taws xob ntawm ib qho cua sov. Tshaj superheat yuav tsum tau tshem tawm los ntawm kev ntxiv cov tshuaj tsuag dej kom ua tiav cov txiaj ntsig xav tau. Cov cua kub siab ntawm cov chav saturated qis dua li ntawm cov chav superheated, uas yuav ua rau kom muaj kev hloov pauv kom zoo dua.
2. Thaum tshav kub kub qhov chaw siab. Lub zog siab ntawm qhov cua sov yog lub zog tsav tsheb tsim los ntawm evaporation, thiab ib qho kev tsim nyog rau lub zog txaus evaporation muaj peev xwm. Nyob rau hauv qhov tsim ntau yam, qhov siab dua ntawm cov khoom siv hluav taws xob thawj zaug, qhov evaporation nrawm dua.
3. Lub tshuab nqus tsev zaum kawg. Qhov kawg lub tshuab nqus tsev kawm ntawv thiab lub siab ntawm lub hauv paus cua sov qhov chaw muab tag nrho cov tshav kub hloov fais fab rau cov nyhuv evaporator. Yog li ntawd, lub tshuab nqus tsev kawm ntawv qib siab kawg ua rau smoother system evaporation. Nyob rau hauv tej yam kev mob, ib tug kawg nqus degree ntawm<-0.08MPa is preferred. When the final vacuum degree decreases, it is necessary to check whether the condenser is scaled or blocked, whether the circulating cooling water volume is sufficient, and whether the circulating water supply temperature is sufficiently low. Of course, under normal operating conditions, the final vacuum degree will decrease with the increase of the pressure of the first effect heating steam, mainly due to an increase in evaporation rather than a malfunction.
4. Txhua qib ua kua zoo. Cov kua dej ruaj khov tuaj yeem tiv thaiv cov evaporation ntau dhau los yog qhov ntsuas ntawm cov evaporator lub ntsiab yeeb nkab.
5. Txhua qhov kub thiab txias. Qhov sib txawv ntawm qhov kub thiab txias ntawm txhua qhov cuam tshuam rho tawm qhov sib txuas ntawm qhov kub ntawm qhov kub ntawm cov nyhuv sab sauv yog qhov sib txawv ntawm qhov kub thiab txias ntawm cov nyhuv no, los yog los ntawm kev txhim kho qhov ntsuas kub ntawm qhov ntsuas kub hauv lub rhaub thiab cov khoom sib cais, qhov sib txawv ntawm qhov kub thiab txias ntawm qhov no. cov nyhuv tuaj yeem pom pom nyeem. Nyob rau hauv qhov chaw ntawm tib lub peev xwm evaporation, qhov sib txawv ntawm qhov sib txawv ntawm txhua qhov cuam tshuam yog qhov ruaj khov, thiab qee qhov cuam tshuam nrog qhov sib txawv ntawm qhov kub thiab txias yuav qhia tau tias txo qis hauv kev hloov hluav taws xob. Nws yog ib qho tsim nyog yuav tsum tau xyuas seb puas muaj qhov ntsuas qhov ntsuas, cov khoom pov tseg, cov dej ntws zoo ntawm cov khoom siv hluav taws xob, thiab kev thaiv ntawm cov kav dej thib ob ntawm ob sab ntawm cov khoom siv hluav taws xob.
6. Sib txawv siab ntawm txhua qhov cuam tshuam. Cov nyhuv ntawm txhua qhov sib txawv ntawm qhov sib txawv yog zoo ib yam li qhov sib txawv ntawm qhov kub thiab txias, uas tuaj yeem siv los xyuas seb cov nyhuv tseem ceeb yog thaiv, ntsuas qhov ntsuas, thiab lwm yam kev txhaum.
7. Chav noj ib chav tsev. Chav noj yog qhov taw qhia tseem ceeb ntawm kev siv lub zog. Nyob rau hauv cov txheej txheem tshwj xeeb, chav noj yog qhov ruaj khov. Thaum muaj kev cuam tshuam cov pa tawm, qhov system chav noj tau txo qis. Qhov kev tshawb nrhiav tseem ceeb yog los xyuas seb cov yeeb nkab condensate tawm ntawm txhua lub tshuab hluav taws xob puas tau xau cov pa, thiab seb lub valve uas tsis yog condensing tau qhib loj heev.
