MVR Distillation Technology:
MVR yog cov ntawv luv ntawm Mechanical Vapor Recompression, uas yog lub zog txuag hluav taws xob uas siv compressed theem nrab vapor raws li qhov cua sov los txo qhov kev thov rau sab nraud lub zog.
MVR thev naus laus zis siv me me ntawm compressor compression ua haujlwm los txhim kho qhov loj ntawm cov khoom siv hluav taws xob qis qis uas nqa los ntawm theem nrab vapor mus rau qib siab rau rov siv dua, yog li nws tseem hu ua MVR cov twj siv hluav taws xob. Kev sib txuas ntawm MVR cov twj siv hluav taws xob cua sov nrog cov txheej txheem kev tsim cov tshuaj distillation, tag nrho rov qab cov cua sov latent ntawm ntauwd saum vapor, thiab txo cov khoom siv txias thiab kub hauv qhov system distillation.
MVR tshav kub twj tso kua mis distillation tshuab tsuas yog siv cua sov vapor thaum lub sij hawm pib ntawm lub distillation system. Tom qab kev ua haujlwm ruaj khov, compressed high-temperature thiab high-pressure vapor yog siv los ua lub tshuab cua sov, txuag hluav taws xob ntau dua 40%, uas yuav pab txo qis kev siv hluav taws xob ntawm cov txheej txheem distillation thiab daws qhov teeb meem ntawm lub zog siab. noj nyob rau hauv chemical kev lag luam.
Kev faib tawm ntawm MVR Distillation System
MVR Distillation Txheej txheem txheej txheem:
MVR cov twj tso kua mis kub distillation feem ntau yog tsim rau cov txheej txheem distillation nrog qhov sib txawv me me ntawm qhov kub thiab txias ntawm sab saum toj thiab hauv qab ntawm tus pej thuam. Txij li thaum lub compression piv ntawm chav compressor feem ntau tsis tshaj 2, yog hais tias qhov kub ntawm lub pej thuam hauv qab yog siab dhau heev lawm, lub condensation kub ntawm lub chav tom qab ib tug compression yog ib qho nyuaj rau ua tau raws li qhov kub ntawm qhov sib txawv uas yuav tsum tau rau kev sib hloov tshav kub nyob rau hauv lub pej thuam hauv qab. ENCO muaj ib-theem distillation unit thiab ntau theem MVR stripping unit. Tus naj npawb ntawm kev teeb tsa theem ntawm ntau theem MVR stripping unit yog txiav txim siab raws li cov khoom siv raw khoom thiab cov kev cai purity ntawm kev sib cais. Raws li qhov chaw sib txawv ntawm MVR stripping unit, nws tau muab faib ua ntau theem MVR stripping unit thiab nruab nrab-theem MVR stripping unit. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
① MVR-cov txheej txheem ob-ntauwd distillation;
MVR-conventional ob-ntauwd distillation txheej txheem ntws. T1 ntauwd txais MVR cov twj tso kua mis kub distillation thiab concentration, thiab T2 ntauwd txais cov pa distillation. Ob lub yees ua haujlwm ntawm lub siab ib txwm muaj. Lub chav V1 nyob rau sab saum toj ntawm T1 ntauwd nkag mus rau lub compressor rau compression thiab ces tsub kom qhov kub thiab txias los muab cua sov rau lub reboiler nyob rau hauv qab ntawm T1 ntauwd. Tom qab lub condensate txo nyob rau hauv siab, ib feem ntawm nws yog refluxed thiab ib feem ntawm nws yog muab rho tawm raws li cov dej khib nyiab. Lub TI ntauwd hauv qab kua (DMAC mloog zoo) nkag mus rau T2 pej thuam, thiab cov dej seem raug tshem tawm rau saum tus pej thuam hauv T2 pej thuam. T2 ntauwd hauv qab kua yog tsim nyog DMAC cov khoom tiav. T1 ntauwd yog rhuab los ntawm compressed chav, thiab T2 ntauwd yog rhuab los ntawm sab nraud chav.
② Peb-theem MVR ib leeg-ntauwd distillation txheej txheem;
Peb-theem MVR ib leeg-ntauwd distillation txheej txheem ntws. Txij li thaum cov khoom tiav DMAC tau txais nyob rau hauv qab ntawm tus pej thuam, qhov kub ntawm cov khoom siv hauv qab yog li ntawm 155 degree ( npuas taw tes kub thaum DMAC cov ntsiab lus yog 99%). Ib-theem compression tsis tuaj yeem ua rau sab saum toj ntauwd chav kub ua tau raws li qhov yuav tsum tau ua ntawm ntauwd hauv qab kub hloov pauv kub qhov sib txawv, yog li ntau theem compression yuav tsum tau siv los ua kom lub siab tshaj plaws chav kub. Raws li tus pej thuam hauv qab qhov kub thiab txias qhov sib txawv ntawm qhov sib txawv (15 degree), nws tuaj yeem pom tias qhov kub thiab txias tawm ntawm qhov kawg compressor yuav tsum ncav cuag 170 degree (155+15=170 degree, saturation kub) , thiab qhov sib thooj siab yog 0.8 MPa (tsis muaj tseeb). Lub pej thuam txais kev ua haujlwm siab, thiab qhov sib piv ntawm txhua theem tau teev tseg yog 2, yog li peb-theem compression tuaj yeem ua tau raws li cov txheej txheem. Tag nrho lub cev tsis xav tau cov cua sov sab nraud, thiab tag nrho cov kev siv hluav taws xob yog muab los ntawm compressor.
③ Peb-theem MVR txheej txheem peb-ntauwd distillation.
Peb-theem MVR peb-ntauwd distillation txheej txheem ntws. Tag nrho peb lub yees ua haujlwm ntawm lub siab ib txwm, thiab cov chav nyob rau saum toj ntawm tus pej thuam tau sau thiab nkag mus rau C1 compressor. Lub chav ua haujlwm tom qab thawj compression yog rhuab los ntawm reboiler nyob rau hauv qab ntawm TI ntauwd, thiab ib feem nkag mus rau hauv lub C2 compressor rau recompression; lub chav ib feem ntawm qhov thib ob compression yog rhuab los ntawm reboiler nyob rau hauv qab ntawm lub T2 ntauwd, thiab ib feem nkag mus rau hauv lub compressor C3 compression thib peb; lub zog ntawm peb compression yog tag nrho cov rhuab los ntawm reboiler nyob rau hauv qab ntawm lub T3 pej thuam. Tom qab lub condensate tom qab tshav kub pauv nyob rau hauv qab ntawm peb yees yog txo nyob rau hauv siab, ib feem ntawm nws yog muab faib mus rau hauv txhua tus pej thuam rau reflux, thiab ib feem ntawm nws yog muab rho tawm raws li cov dej khib nyiab. Tag nrho lub cev tsis xav tau cov cua sov sab nraud, thiab tag nrho cov kev siv hluav taws xob yog muab los ntawm compressor.
Qhov zoo ntawm MVR Distillation Technology:
Distillation technology, uas yog, compressing cov dej vapor nyob rau sab saum toj ntawm lub pej thuam los ntawm ib tug neeg kho tshuab chav compressor, ua rau nws kub thiab siab, thiab condensing nws nyob rau hauv lub reboiler kom hloov tshav kub rau cov khoom nyob rau hauv qab ntawm lub pej thuam, thiab tsuas yog siv. lub compressor tswj lub zog sib npaug ntawm cov distillation system. Ib qho me me ntawm cov hluav taws xob yog siv los txhim kho cov qib thermal ntawm cov chav nyob rau sab saum toj ntawm tus pej thuam, thiab cov cua sov latent ntawm vaporization ntawm cov chav nyob rau saum cov pej thuam tau zoo zoo, uas txo cov cua sov hauv qab. tus pej thuam thiab txo qhov kev siv ntawm lub peev xwm txias rau saum lub pej thuam, yog li ua tiav lub hom phiaj ntawm kev txuag hluav taws xob.
①Distillation thev naus laus zis tuaj yeem txuag tau 90% ntawm chav dej thiab cov dej txias, txuag cov nqi khiav lag luam ntau.
② Lub Distillation thiab stripping composite ntaus ntawv thiab nws cov txheej txheem txheej txheem tsim los ntawm ENCO koom nyob rau hauv lub teb ntawm distillation txheej txheem technology. Los ntawm kev sib txuas zoo ntawm cov txheej txheem distillation thiab cov txheej txheem stripping, cov txheej txheem kev siv hluav taws xob sib xyaw ua kua sib cais tuaj yeem txo qis.
③ Nws yog ib qho yooj yim thiab yooj yim rau kev khiav lag luam, muaj zog adaptability rau cov kev hloov nyob rau hauv lub concentration ratio ntawm raw cov ntaub ntawv ua kua, thiab muaj loj ua hauj lwm yooj. Thaum txuag lub zog noj, nws tuaj yeem ua rau kev sib cais ntawm cov kua sib xyaw ua ke ntau dua, txhim kho qhov purity ntawm cov kua sib cais, thiab ua tau raws li cov txheej txheem tsim khoom.
Scope ntawm daim ntawv thov ntawm Distillation technology
MVR cov twj tso kua mis distillation yog tsim nyog rau kev sib cais ntawm qhov sib txawv ntawm qhov sib txawv me me xws li ethanol-isopropanol, uas tuaj yeem txo qhov kev siv zog ntawm cov txheej txheem sib cais. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev rov qab los ntawm qhov tsis tshua muaj siab thiab kub kub ntawm cov kuab tshuaj organic (xws li DMF, DMSO, DMAC, thiab lwm yam), thiab tuaj yeem siv rau cov concentration ntawm cov kuab tshuaj xws li ethanol, methanol, thiab dichloromethane.
