Txoj Cai Ua Haujlwm Ntawm MVR Evaporator

MVR evaporator yog qhov sib txawv ntawm cov nyhuv zoo ib yam uas ntog zaj duab xis lossis ntau cov nyhuv ntog zaj duab xis evaporators. MVR yog ib chav tsev evaporator uas sib xyaw ua ke ntau cov nyhuv ntog zaj duab xis evaporators. Raws li cov khoom xav tau, segmented evaporation tau txais yuav. Ntawd yog, thaum cov khoom tsis tuaj yeem ncav cuag qhov xav tau ntawm qhov xav tau tom qab dhau los ntawm cov nyhuv thawj zaug, cov khoom tau muab tso rau sab saud ntawm cov nyhuv los ntawm cov kav dej sab nraud ntawm cov nyhuv los ntawm lub tshuab nqus tsev twj tso kua mis ntawm qhov qis ntawm cov nyhuv. tom qab tawm hauv cov nyhuv, Tom qab ntawd, los ntawm kev rov ua dua los ntawm tus effector, qhov xav tau concentration tiav.
Sab hauv ntawm cov nyhuv yog teem nrog nyias cov hlab, sab hauv uas yog cov khoom, thiab sab nraud uas yog chav. Thaum lub sij hawm ntws ntawm cov khoom los ntawm sab saum toj mus rau hauv qab, qhov chaw nyob rau hauv cov hlab ntsha nce, ua rau cov khoom ntws nyob rau hauv ib tug zaj duab xis zoo li yuav ua rau kom lub cua sov cheeb tsam. Lub siab tsis zoo yog tsim nyob rau hauv cov nyhuv los ntawm lub tshuab nqus tsev twj, txo qhov kub ntawm cov dej hauv cov khoom thiab ua tiav cov concentration. Lub evaporation kub ntawm cov khoom yog nyob ib ncig ntawm 60 degree.
Cov dej condensed, ib co chav, thiab cov seem seem uas tsim los ntawm cov cua sov thiab evaporation ntawm cov khoom los ntawm cov nyhuv lub cev yog sib cais los ntawm ib tug separator. Cov dej condensed ntws tawm ntawm qhov qis ntawm qhov sib cais rau preheating cov khoom nkag mus rau hauv cov nyhuv ntawm lub cev. Cov chav yog pressurized los ntawm ib tug kiv cua booster (qhov siab dua lub zog siab, qhov siab dua qhov kub), thiab tom qab ntawd cov cua compression converges los ntawm lub raj xa dej thiab dhau los ntawm lub cev muaj zog dua.
Thaum cov cuab yeej pib, ib feem ntawm chav yog xav tau rau preheating. Tom qab ua haujlwm li qub, qhov xav tau chav yuav raug txo kom tsawg. Thaum lub sij hawm tus txheej txheem ntawm pressurizing lub thib ob chav los ntawm lub kiv cua booster, hluav taws xob lub zog hloov dua siab tshiab rau hauv chav kub lub zog. Yog li ntawd, qhov xav tau ntawm cov khoom siv thaum lub sijhawm ua haujlwm raug txo, thiab qhov xav tau hluav taws xob tau nce ntxiv.
Qhov ntsuas kub ntawm cov khoom tseem nyob ib puag ncig 60 degree thoob plaws hauv tag nrho cov txheej txheem ntws, thiab qhov sib txawv ntawm qhov kub ntawm cov cua sov thiab cov khoom kuj tseem khaws cia nyob ib ncig ntawm 5-8 degree . Qhov me me ntawm qhov sib txawv ntawm cov khoom thiab cov cua kub nruab nrab, qhov ntau conducive nws yog los tiv thaiv cov khoom zoo thiab zoo tiv thaiv tubing sticking.
Thaum lub concentration ntawm cov khoom nyob ib ncig ntawm 50%, tsuas yog MVR evaporator tuaj yeem ua tiav nws. Thaum qhov xav tau concentration yog 60%, flash evaporation khoom yuav tsum tau muab ntsia.
