MVR yuam kev ncig evaporator cov ntsiab lus
Cov evaporator no yog kev sib xyaw ua ke ntawm MVR evaporator thiab yuam kev ncig evaporation txheej txheem. Kev siv MVR thiab cov txheej txheem yuam kev tuaj yeem muab cov kev khiav ceev txaus rau kev loj hlob siv lead ua, txo cov kev daws teeb meem supersaturation, tsis txhob daws qhov tawg nucleation, ua kom cov nqi ntws ntawm cov cua sov chamber raj, ua kom cov cua sov hloov coefficient thiab tsis txhob thaiv cov khoom thaiv. Cov txiaj ntsig ntawm kev txo cov nqi khiav lag luam yog qhov tseem ceeb, thiab cov txiaj ntsig kev lag luam muaj txiaj ntsig tau nce ntxiv.
Forced ncig evaporator muaj pes tsawg leeg:
Qhov yuam kev ncig evaporator muaj xws li txhua qhov cuam tshuam cua sov chamber, evaporation crystallization chamber, condenser, ncig twj tso kua mis, lub tshuab nqus tsev thiab tso dej, roj-kua sib cais chamber, theem nrab chav flash tank, ntsev separator, kev khiav hauj lwm platform, nrhiav kom tau cov cuab yeej thiab hluav taws xob ntsuas tswj txee thiab valve thiab pipeline system.
Cov yam ntxwv ntawm kev quab yuam ncig evaporator:
Txoj haujlwm ua haujlwm:
Cov khoom yog rhuab los ntawm chav sab nraum lub tshav kub exchanger tube nyob rau hauv lub tshav kub exchanger raj kom qhov kub thiab txias. Nyob rau hauv qhov kev txiav txim ntawm lub twj tso kua mis, cov khoom nce mus rau lub separator, thiab cov khoom evaporates nyob rau hauv lub separator vim qhov txo nyob rau hauv static siab ntawm cov khoom.
evaporation ua rau theem ob chav dej ntws los ntawm cov khoom siv, cov khoom siv yog concentrated los tsim supersaturation thiab crystallization, thiab cov khoom siv supersaturated nkag mus rau hauv lub twj tso kua mis quab yuam thiab nkag mus rau hauv lub tshav kub exchanger nyob rau hauv qhov kev txiav txim ntawm lub twj tso kua mis. Cov khoom yog tsis tu ncua evaporated thiab concentrated los yog concentrated thiab crystallized nyob rau hauv lub voj voog no. Cov khoom siv lead ua slurry yog tawm los ntawm cov raj xa dej los ntawm lub twj tso kua mis tawm. Qhov thib ob chav nyob rau hauv lub evaporator separator yog purified los ntawm kev sib cais thiab defoaming ntaus ntawv nyob rau sab sauv ntawm lub evaporator separator thiab ces thauj mus rau lub compressor. Lub compressor compresses cov chav thib ob thiab thauj nws mus rau lub plhaub sab ntawm lub tshav kub exchanger rau siv raws li evaporator cua sov chav, realizing thermal zog ncig thiab nruam evaporation.
Qhov no MVR evaporator system muaj xws li:
Cov cuab yeej tseem ceeb ntawm kev yuam kev MVR evaporator muaj lub rhaub dej, chav sib cais, compressor, lub twj tso kua mis, thiab lub tshuab lim. Lub thiaj li hu ua yuam kev ncig yog hais txog qhov yuam kev ntawm cov khoom siv ntawm lub tshuab cua sov thiab qhov sib cais chamber uas tau tsav los ntawm lub twj tso kua mis. Cov khoom yog rhuab thaum ntws los ntawm lub rhaub, thiab qhov kub thiab txias yog tsim nyog. Thaum circulating mus rau lub sib cais chamber, lub static siab yog txo thiab nws pib boil thiab vaporize, cov tshuaj yog concentrated, supersaturation yog tsim, thiab cov muaju yog saturated thiab precipitated thiab loj hlob.
Kev quab yuam ntawm cov ntaub ntawv ntawm lub tshav kub hloov cov raj ua kom lub tshav kub hloov coefficient, tshwj xeeb tshaj yog cov khoom siv lead ua slurry uas muaj cov muaju kom zoo flushes lub tshav kub pauv phab ntsa nto, uas muaj peev xwm cuam tshuam scaling tshwm sim los ntawm hardness (tus tsim ntawm lub yuam kev ncig MVR evaporator tsim los ntawm Kang Jinghui tau zam qhov tshwm sim ntawm scaling thiab yeeb nkab clogging ntawm cov khoom siv lead ua nyob rau hauv lub tshav kub exchanger).
Nta:
1. Haum rau cov khoom uas muaj viscosity siab lossis muaj cov khoom;
2. Haum rau ntau txoj kev crystallization nrog loj concentration piv;
3. Cov khoom ntim loj, cov kav dej ntws siab, tsis yooj yim rau cov phab ntsa qhuav lossis nplai;
4. Kev siv zog ntau dua piv rau cov yeeb yaj kiab ntog.
Haum rau cov khoom siv concentration thiab pre-concentration ntawm ntsev crystallization, ib tug dav siv evaporator hom, tshwj xeeb tshaj yog haum rau cov khoom los nag lossis dej tshwj xeeb evaporation crystallization thaum lub sij hawm evaporation. Cov khoom nyob rau hauv lub evaporator yog tsav los ntawm sab nraud quab yuam kom circulate tshav kub pauv, uas yog tshwj xeeb tshaj yog tsim nyog rau kev tswj cov tshuaj supersaturation thiab cultivating crystals.
Kev siv ntau yam:
(1) Nws muaj lub zog siv hluav taws xob ntau heev;
(2) Nws muaj ntau yam kev thov scenarios, thiab yog resistant rau salting tawm thiab scaling;
(3) Nws yog cov khoom siv zoo tshaj plaws rau cov siv lead ua evaporator, nrog cov siv lead ua loj loj thiab nqaim faib;
(4) Nws yog tsim rau feem ntau cov khoom evaporation thiab crystallization zaus: sodium chloride, sodium sulfate, sodium phosphate, ammonium chloride, cobalt sulfate, cobalt chloride, nickel sulfate, ammonium sulfate, sodium thiosulfate, sodium fluoride, sodium sulfite, lithium hydroxide, sodium nitrate, potassium nitrate, ammonium nitrate, tooj liab sulfate, calcium ammonium nitrate, barium nitrate, sodium bromide, poov tshuaj bromide, zinc sulfate, sodium borate, ntau yam organic khoom evaporators, thiab lwm yam.
