Coulter Cua Lifter rau Cellulose Ether Kev Lag Luam

Lub coulter-hom cua lifter muaj peev xwm ua haujlwm tas li yog tsim, uas yog siv los ua cov khoom siv ziab khaub ncaws hauv cov txheej txheem ntawm kev tsim cov cellulose ether los ntawm cov txheej txheem hnyav, kom paub txog kev ua haujlwm zoo thiab txuas ntxiv ntawm cov txheej txheem decoholization ziab, thiab thaum kawg paub. lub hom phiaj ntawm CMC ntau lawm. Kev ua haujlwm tsis tu ncua.

Cov lus tseem ceeb: carboxymethyl cellulose ether (CMC luv luv); kev ua haujlwm tsis tu ncua; coulter cua lifter

Hauv cov txheej txheem kev tsim cov cellulose ether los ntawm cov txheej txheem hnyav, cov khoom nyoos ntawm carboxymethyl cellulose (tom qab no hu ua CMC) tau los ntawm cov tshuaj tiv thaiv etherification tuaj yeem tau txais los ntawm kev ua kom zoo xws li kev ntxuav tsis tu ncua, kev kho kom qhuav, crushing thiab granulation, thiab lwm yam. Tsuas yog ib feem ntawm ethanol uas muaj nyob rau hauv cov crude CMC saum toj no yog rov qab los ntawm distillation nrog rau sodium ntsev thaum lub sij hawm neutralization thiab ntxuav txheej txheem, thiab lwm yam ethanol yog khaws cia nyob rau hauv lub crude CMC, qhuav, pulverized, granulated thiab ntim rau hauv tiav CMC. . rov ua dua. Nyob rau hauv xyoo tas los no, tus nqi ntawm cov kuab tshuaj organic tau nce ntxiv. Yog tias ethanol tsis tuaj yeem rov ua dua tshiab, nws yuav tsis tsuas yog ua rau cov khoom siv pov tseg xwb, tab sis kuj nce tus nqi tsim khoom ntawm CMC, uas yuav cuam tshuam cov khoom lag luam thiab txo cov khoom sib tw. Hauv cov ntsiab lus no, qee cov tuam txhab CMC txhim kho cov txheej txheem ntws thiab siv lub tshuab nqus tsev rake hauv cov txheej txheem ntawm kev sib txuas thiab ziab, tab sis lub tshuab nqus tsev rake tsuas tuaj yeem ua haujlwm tsis tu ncua, thiab kev siv zog ua haujlwm siab, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. CMC ntau lawm. automation xav tau. Pab pawg R & D ntawm Zhejiang Provincial Research Institute of Chemical Industry tau tsim ib coulter-type air stripper rau CMC dealcoholization thiab ziab txheej txheem, yog li ntawd ethanol yuav sai sai thiab tag nrho volatilized los ntawm CMC crude khoom thiab recycled rau siv, thiab tib yam. sij hawm ua kom tiav cov haujlwm ntawm CMC kom qhuav cov txheej txheem. Thiab nws tuaj yeem paub txog kev ua haujlwm tas mus li ntawm CMC ntau lawm, thiab nws yog ib qho khoom siv zoo tshaj plaws hloov khoom siv rau lub tshuab nqus tsev vacuum hauv CMC cov txheej txheem ntau lawm.

1. Cov qauv tsim ntawm coulter cua lifter rau cellulose ether kev lag luam

1.1 Cov yam ntxwv ntawm coulter cua lifter

Lub coulter hom cua lifter yog tsim los ntawm kev sib kis mechanism, kab rov tav cua sov lub tsho lub cev, plow qhia, ya pab pawg neeg, tso tank, tso tawm mechanism thiab chav nozzle thiab lwm yam tseem ceeb Cheebtsam. Cov qauv no tuaj yeem nruab nrog cov khoom siv pub mis rau ntawm qhov nkag thiab cov khoom tso tawm ntawm qhov hluav taws xob. Lub volatilized ethanol raug tso tawm los ntawm lub tank tso tawm thiab rov siv dua, yog li paub txog kev ua haujlwm tas li ntawm CMC ntau lawm.

1.2 Lub hauv paus ntsiab lus ua haujlwm ntawm coulter cua lifter

Nyob rau hauv qhov kev txiav txim ntawm lub coulter, CMC crude khoom turbulences nyob rau hauv lub puab phab ntsa ntawm lub tog raj kheej nyob rau hauv lub circumferential thiab radial cov lus qhia ntawm ib sab, thiab yog muab pov raws li ib txwm coj ntawm ob sab ntawm lub coulter ntawm qhov tod tes; thaum cov khoom thaiv thaiv cov khoom ntws los ntawm cov riam ya, Nws kuj tau tawg ua kom tawg los ntawm kev kub ceev rotating ya riam. Raws li kev sib koom ua ke ntawm coulters thiab rab riam ya, CMC cov khoom siv roj av tau tig nrawm thiab crushed kom nce thaj tsam ntawm ethanol tuaj yeem hloov pauv; Nyob rau tib lub sij hawm, cov khoom nyob rau hauv lub tog raj kheej yog rhuab los ntawm lub tsho chav thiab lub chav yog kis mus rau hauv lub tog raj kheej kom ncaj qha tshav kub cov ntaub ntawv nyob rau hauv ob chav ua hauj lwm ntawm ethanol, lub volatilization efficiency thiab cov nyhuv ntawm ethanol yog zoo heev txhim kho, thiab lub ethanol yog sib cais sai thiab meej. Nyob rau tib lub sij hawm ntawm dealcoholization, lub chav nyob rau hauv lub tsho heats cov khoom nyob rau hauv lub tog raj kheej thiab ua tiav cov txheej txheem ziab ntawm CMC. tom qab ntawd. CMC tom qab dealcoholization thiab ziab tuaj yeem nkag mus rau tom ntej crushing, granulation thiab cov khoom ntim cov txheej txheem tom qab raug tso tawm los ntawm cov txheej txheem tawm.

1.3 Tshwj xeeb coulter qauv thiab kev npaj

Los ntawm kev tshawb fawb txog cov yam ntxwv ntawm CMC, cov kws tshawb fawb tau xaiv los siv lub coulter tov khoom tsim nyob rau hauv lub sij hawm thaum ntxov raws li cov qauv yooj yim, thiab txhim kho cov qauv zoo thiab coulter kev npaj ntawm coulter ntau zaus. Qhov kev ncua deb ntawm ob lub coulters uas nyob ib sab nyob rau hauv lub circumferential kev taw qhia Qhov suav nrog yogα, α yog 30-180 degrees, teem nyob rau hauv ib tug kauv ntawm lub ntsiab ncej, thiab lub rear kawg ntawm lub coulter muaj ib tug arc concave los txhim kho lub splashing quab yuam ntawm cov khoom raws li ib txwm kev taw qhia ntawm ob sab ntawm lub coulter, thiaj li hais tias cov khoom. yog pov thiab crushed ntau npaum li sai tau los ua kom cov cheeb tsam saum npoo uas ethanol tuaj yeem volatilized, kom cov ethanol extraction hauv CMC crude khoom ntau txaus.

1.4 Tsim ntawm lub tog raj kheej nam piv

Txhawm rau kom paub qhov kev ua haujlwm tas mus li ntawm lub tshuab nqa huab cua, qhov ntev ntawm lub thoob yog ntev dua li ntawm cov khoom siv dav dav. Los ntawm ntau qhov kev txhim kho hauv kev tsim qauv ntawm qhov sib piv ntawm qhov ntev mus rau txoj kab uas hla ntawm lub cev yooj yim, qhov zoo tshaj qhov ntev-rau-txoj kab uas hla ntawm lub cev yooj yim tau txais thaum kawg, kom cov ethanol tuaj yeem ua rau tag nrho cov volatilized thiab muab los ntawm lub tank tso rau hauv. lub sijhawm, thiab kev ua haujlwm ntawm CMC kom qhuav cov txheej txheem tuaj yeem ua tiav tib lub sijhawm. CMC tom qab dealcoholization thiab ziab ncaj qha nkag mus rau hauv cov txheej txheem ntawm crushing, granulation thiab cov khoom ntim, realizing lub full-line automation ntawm CMC ntau lawm.

1.5 Tsim cov nozzles tshwj xeeb

Muaj ib lub nozzle tshwj xeeb nyob rau hauv qab ntawm lub tog raj kheej rau steaming. Lub nozzle yog nruab nrog lub caij nplooj ntoos hlav. Thaum cov chav nkag mus, qhov sib txawv ntawm qhov siab ua rau lub hau npog qhib. Thaum lub ncu tsis ntws, lub nozzle npog kaw lub nozzle nyob rau hauv qhov nro ntawm lub caij nplooj ntoos hlav los tiv thaiv cov crude CMC los ntawm kev tso tawm. Ethanol ntws los ntawm lub nozzle.

2. Cov yam ntxwv ntawm coulter cua lifter

Lub coulter-type air lifter muaj cov qauv yooj yim thiab tsim nyog, tuaj yeem rho tawm ethanol sai thiab tag nrho, thiab tuaj yeem paub txog kev ua haujlwm tas li ntawm CMC dealcoholization drying txheej txheem, thiab muaj kev nyab xeeb thiab yooj yim rau nruab, khiav lag luam thiab tswj. Qee cov neeg siv khoom tau muab kev tawm tswv yim tom qab siv nws. Kev siv lub tshuab no tsis yog tsuas yog muaj kev rov zoo siab ntawm kev rho tawm ethanol thiab kev siv hluav taws xob tsawg, tab sis kuj txhim kho cov khoom zoo, txo cov nqi tsim khoom, thiab txuag cov peev txheej ethanol. Nyob rau tib lub sijhawm, nws zoo heev txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm kev ua haujlwm, thiab ua tau raws li CMC cov cai uas twb muaj lawm. Industrial ntau lawm automation yuav tsum.

3. Daim ntawv thov kev cia siab

Nyob rau hauv xyoo tas los no, kuv lub teb chaws CMC kev lag luam yog hloov los ntawm kev siv zog ntau lawm mus rau automated ntau lawm, nquag tsim tshiab cov cuab yeej tshawb fawb thiab kev loj hlob, thiab txuas ntxiv txhim kho cov txheej txheem ua ke nrog cov yam ntxwv ntawm cov cuab yeej siv, kom paub txog CMC ntau lawm ntawm tus nqi qis. thiab npaj cov khoom zoo. Lub hom phiaj ntawm CMC cov tuam txhab tsim khoom. Lub coulter hom cua lifter ua tau raws li qhov yuav tsum tau ua thiab yog qhov kev xaiv zoo tshaj plaws rau CMC cov cuab yeej tsim khoom.
