MVR evaporator yog ib yam khoom siv evaporator tshwj xeeb. Tam sim no, nws tau dav siv thiab tau siv ntau yam. Thaum siv nws, koj yuav tsum nkag siab tsis yog nws txoj kev ua haujlwm nkaus xwb, tab sis kuj nws qhov kev ua tau zoo. Hnub no, kuv yuav qhia txog cov haujlwm ntawm cov khoom kom ntxaws rau koj.
1. Cov khoom siv evaporates cov ntaub ntawv ntawm qhov kub thiab txias, nrog rau qhov kub ntawm 35 ° C thiab 100 ° C, thiab yuav tsis tsim npuas. Cov khoom siv thiab cov kua yog sib xws heev. Tsis tas li ntawd, cov khoom siv yuav tsis tas siv los yog coking. Tsis tas li ntawd, cov cua sov deformation ntawm cov khoom kuj yog me me heev.
2. Tus nqi ntawm cov khoom siv feem ntau yog siab, tshwj xeeb tshaj yog cov neeg kho tshuab compression hom MVR evaporator, uas yog kwv yees li ob npaug ntawm tus nqi ntawm ntau cov evaporator, tab sis rau cov haujlwm tshiab, MVR evaporator yog qhov tsim nyog dua. Thiab tus nqi tuaj yeem rov qab los ntawm lub sijhawm luv luv. Piv txwv li, thaum lub sijhawm khiav dhau 300 hnub, tus nqi tuaj yeem rov qab tau. Piv nrog rau nws tus nqi yuav khoom, qhov no yog tus nqi pheej yig. Rau cov neeg kho tshuab compression hom MVR evaporator, nws tuaj yeem hloov pauv cov evaporator qub, thiab muaj zog txuag hluav taws xob thiab kev tiv thaiv ib puag ncig zoo. Feem ntau, tus nqi tuaj yeem rov qab tau tom qab siv ntau tshaj 500 hnub
3. Kev siv lub zog ntawm cov khoom siv yog hluav taws xob hluav taws xob. Rau txhua tuj dej evaporated, nws yuav haus 15 mus rau 27 degrees dej. Yog tias nws yog cov khoom siv uas tsis tshua muaj kub kub, lub zog hluav taws xob siv yuav tsawg dua 20 degrees. Piv nrog rau cov tshuaj evaporator ib txwm muaj, qhov no yog qhov txiaj ntsig zoo, uas tuaj yeem txuag tau ntau dua 60 feem pua ntawm lub zog.
Nws tuaj yeem pom tau tias cov khoom no yog cov khoom siv txuag hluav taws xob thiab ib puag ncig zoo. MVR evaporator yuav tsis tsim cov pa phem thaum siv, thiab nws yog ib qho kev txuag hluav taws xob, uas zoo dua li siv cov khoom siv roj; Nws kuj tseem tuaj yeem ua haujlwm tsis tu ncua yam tsis ua haujlwm; Tsis tas li ntawd, hom khoom raug xaiv yuav tsum raug xaiv thaum yuav khoom.
MVR evaporator yog hom tshiab ntawm cov khoom siv hluav taws xob txuag hluav taws xob feem ntau siv hauv kev lag luam tshuaj. Cov cuab yeej siv hluav taws xob tsis zoo thiab tsis tshua muaj siab siv tshuab thiab lub zog huv los ua kom muaj zog ua kom muaj zog los cais cov dej hauv nruab nrab. Nws yog ib qho kev siv tshuab evaporation siab heev. Nws yog ib qho khoom kho dua tshiab los hloov cov evaporator ib txwm muaj.
MVR evaporator yog qhov sib txawv ntawm qhov sib txawv ntawm ib qho kev cuam tshuam ntog zaj duab xis evaporator lossis ntau qhov cuam tshuam ntog zaj duab xis evaporator. MVR yog ib qho evaporator nrog kev sib xyaw ua ke ntau qhov cuam tshuam ntog zaj duab xis evaporator. Thaum qhov xav tau concentration tsis tuaj yeem ncav cuag tom qab dhau los ntawm tus effector ib zaug, cov khoom yog pumped mus rau sab sauv ntawm effector los ntawm lub tshuab nqus tsev twj tso kua mis nyob rau hauv qab ntawm lub effector los ntawm lub sab nraud yeeb nkab ntawm lub effector tom qab tawm mus, thiab ces dhau mus. los ntawm tus effector dua thiab dua los ntawm qhov rov ua dua channel kom txog thaum lub effector mus txog qhov xav tau concentration. Sab hauv ntawm lub cev muaj zog yog ib kab ntawm cov hlab ntsha nyias, nrog cov khoom siv sab hauv thiab chav sab nraud. Nyob rau hauv cov txheej txheem ntawm cov khoom ntws los ntawm sab saum toj mus rau hauv qab, qhov cua sov cheeb tsam yog nce vim qhov nce hauv cheeb tsam ntawm MVR evaporator raj, thiab cov khoom ntws los ntawm cov yeeb yaj kiab. Lub siab tsis zoo yog tsim nyob rau hauv MVR evaporator, uas txo qhov kub ntawm cov dej hauv cov khoom kom ua tiav cov concentration. Lub evaporation kub ntawm cov khoom yog hais txog 60 degree.
Cov dej condensed generated tom qab cov khoom yog rhuab thiab evaporated los ntawm cov nyhuv lub cev, ib feem ntawm cov chav thiab cov seem seem tom qab cov nyhuv lub cev yog rhuab yog sib cais los ntawm lub separator. Condensate ntws tawm ntawm qhov qis ntawm qhov sib cais kom preheat cov khoom nkag mus rau lub cev. Cov chav yog pressurized los ntawm tus kiv cua supercharger (qhov siab dua lub zog siab, qhov kub thiab txias dua), thiab tom qab ntawd cov cua compressorized tau ua ke los ntawm cov yeeb nkab, thiab cov chav yuav dhau los ntawm cov nyhuv ntawm lub cev dua.
Thaum MVR evaporator pib, ib co chav yuav tsum tau ua kom preheating. Tom qab kev ua haujlwm ib txwm muaj, tus nqi ntawm chav yuav tsum tau txo qis heev. Thaum lub sij hawm tus txheej txheem ntawm pressurizing lub thib ob chav los ntawm tus kiv cua supercharger, lub zog hluav taws xob yog hloov dua siab tshiab rau hauv lub tshav kub lub zog ntawm lub chav, yog li cov chav yuav tsum tau rau lub MVR evaporator ua hauj lwm yog txo, thiab cov hluav taws xob yuav tsum tau ntau zog.
Thaum lub sij hawm tag nrho cov txheej txheem ntws ntawm cov nyhuv, qhov kub ntawm cov khoom yog ib txwm nyob ib ncig ntawm 60 degree, thiab qhov kub ntawm qhov sib txawv ntawm cov cua sov thiab cov khoom yog nyob ib ncig ntawm 5-8 degree . Qhov me me qhov kub ntawm qhov sib txawv ntawm cov khoom thiab cov cua sov nruab nrab, qhov kev tiv thaiv zoo dua ntawm cov khoom. Thaum cov khoom concentration yog li 50 feem pua, tsuas yog MVR evaporator tuaj yeem ua tiav. Thaum qhov xav tau concentration yog 60 feem pua, yuav tsum muaj cov khoom siv flash.
