Crystallizer

1. Kev txhais: acrystallizeryog ib lub thawv zoo li lub thawv nrog lub tsho rau ntawm phab ntsa lossis ib lub raj nab hauv pwm kom sov los yog txias cov tshuaj hauv lub tank.Lub tank crystallization tuaj yeem siv ua evaporation crystallizer lossis txias crystallizer.Txhawm rau txhim kho kev siv dag zog ntawm cov khoom siv lead ua, ib qho stirrer tuaj yeem ntxiv rau hauv lub tank.Lub tank crystallization tuaj yeem siv rau kev ua haujlwm tsis tu ncua lossis ua haujlwm tsis sib xws.Cov siv lead ua tau los ntawm kev ua haujlwm tsis sib xws yog qhov loj, tab sis cov siv lead ua tau yooj yim txuas rau hauv cov pob zeb siv lead ua thiab nkag rau niam cawv, uas cuam tshuam rau cov khoom siv purity.Lub crystallizer muaj cov qauv yooj yim thiab siv zog tsawg, thiab tsim nyog rau kev tsim cov khoom me me (xws li tshuaj reagents thiab biochemical reagents).
2. yuam kev ncig
Cov qauv siv hluav taws xob cuam tshuam nrog kev sib txuas mus rau crystallizer nrog crystal slurry ncig.Thaum lub sijhawm ua haujlwm, cov kua pub yog ntxiv los ntawm qhov qis ntawm cov yeeb nkab, sib xyaw nrog cov khoom siv lead ua slurry tawm hauv qab ntawm crystallization chamber, thiab tom qab ntawd tso rau hauv cov cua sov chamber.Crystal slurry yog rhuab nyob rau hauv lub cua sov chamber (feem ntau 2 ~ 6 ℃), tab sis tsis evaporate.Tom qab kub siv lead ua slurry nkag mus rau hauv lub crystallization chamber, nws boils kom cov tshuaj ncav cuag lub supersaturated lub xeev, yog li ib feem ntawm lub solute yog tso rau saum npoo ntawm suspended grain kom cov siv lead ua loj hlob tuaj.Cov siv lead ua slurry raws li cov khoom yog tawm los ntawm sab sauv ntawm cov yeeb nkab circulating.Forced ncig evaporation crystallizer muaj peev xwm ntau lawm, tab sis qhov loj me me ntawm cov khoom yog dav.
3. DTB hom
Ntawd yog, cov cua ntsawj ntshab baffle evaporation crystallizer kuj yog siv lead ua slurry circulating crystallizer (saib daim duab xim).Ib sab elutriation txuas nrog rau sab qis ntawm lub cuab yeej, thiab cov lus qhia lub tog raj kheej thiab lub cylindrical baffle tau teeb tsa hauv lub cuab yeej.Thaum lub sij hawm ua hauj lwm, cov khoom kub saturated kua yog txuas ntxiv mus rau qhov qis ntawm cov yeeb nkab circulating, tov nrog niam kua nrog cov muaju me me nyob rau hauv cov yeeb nkab circulating, thiab ces pumped mus rau lub rhaub.Cov tshuaj rhuab ntws mus rau hauv lub crystallizer ze rau hauv qab ntawm lub raj cua ntsawj ntshab thiab raug xa mus rau cov kua theem raws li lub raj cua ntsawj ntshab los ntawm ib tug maj mam tig kiv cua.Cov tshuaj yog evaporated thiab txias rau ntawm cov kua nto kom ncav cuag lub xeev supersaturated, nyob rau hauv uas ib co solutes tso rau saum npoo ntawm cov khoom uas raug tshem tawm kom cov siv lead ua loj hlob.Kuj tseem muaj thaj chaw sib hais nyob ib puag ncig lub baffle.Nyob rau hauv qhov chaw nyob, cov khoom loj me me, thaum cov khoom me me nkag mus rau hauv cov yeeb nkab nrog cov kua thiab yaj hauv qab cua sov.Crystal nkag mus rau hauv elutriation kem nyob rau hauv qab ntawm lub crystallizer.Txhawm rau ua kom cov khoom me me ntawm cov khoom siv crystalline kom zoo ib yam li qhov ua tau, ib feem ntawm niam cawv los ntawm thaj chaw sib haum xeeb yog ntxiv rau hauv qab ntawm elutriation kem, thiab cov khoom me me rov qab mus rau lub crystallizer nrog cov kua ntws los ntawm kev siv cov dej num. ntawm kev faib tawm hydraulic, thiab cov khoom siv crystalline raug tso tawm los ntawm sab qis ntawm kab elutriation.
4. Oslo hom
Kuj hu ua Kristal crystallizer, nws yog ib tug niam cawv circulating nruam crystallizer (Fig. 3).Cov kua dej ua haujlwm tau muab ntxiv rau hauv cov yeeb nkab, sib xyaw nrog cov kua dej ntws hauv cov yeeb nkab, thiab xa mus rau chav cua sov.Cov tshuaj rhuab evaporates nyob rau hauv lub evaporation chamber thiab mus txog supersaturation, thiab nkag mus rau lub crystal fluidized txaj hauv qab lub evaporation chamber los ntawm lub hauv paus raj (saib fluidization).Nyob rau hauv lub siv lead ua fluidized txaj, supersaturated solute nyob rau hauv cov kev daws yog tso rau saum npoo ntawm cov khoom tshem tawm kom cov siv lead ua loj hlob tuaj.Crystal fluidized txaj hydraulically cais cov khoom.Cov khoom loj yog nyob hauv qab thiab cov khoom me me yog nyob rau saum.Cov khoom siv crystalline uas muaj qhov sib txawv me me yog tawm los ntawm lub hauv qab ntawm lub txaj fluidized.Cov khoom zoo nyob rau hauv lub txaj fluidized ntws mus rau hauv cov yeeb nkab circulating nrog niam kua thiab yaj cov pob zeb me me thaum rov ua kom sov.Yog hais tias lub cua sov chamber ntawm Oslo evaporative crystallizer yog hloov los ntawm lub txias chamber thiab lub evaporation chamber raug tshem tawm, lub Oslo txias crystallizer yog tsim.Lub ntsiab qhov tsis zoo ntawm cov cuab yeej no yog cov kuab tshuaj yog ib qho yooj yim rau tso rau ntawm lub tshav kub hloov chaw thiab kev ua haujlwm yog teeb meem, yog li nws tsis yog dav siv.
5. Breakout twv ua ntej
(1) Saib xyuas qhov kev sib txhuam los kwv yees kev tawg.Cov kev siv feem ntau yog nruab ib lub dynamometer ntawm lub vibration hydraulic lub tog raj kheej, lub tester ntawm lub vibration device, thiab ib qho accelerometer thiab Dynamometer ntawm cov pwm los xyuas qhov kev sib txhuam.Vim tias qhov kev ua haujlwm ntawm cov cuab yeej vibration muaj qhov cuam tshuam zoo rau kev ntsuas kev sib txhuam, qhov ntsuas qhov tseeb ntawm kev sib txhuam yog qhov nyuaj los xyuas kom meej.Txawm hais tias txoj kev no yog qhov yooj yim, nws qhov tseeb tsis yog siab heev, thiab nws tsuas tuaj yeem kwv yees kev sib koom ua ke, uas feem ntau ua rau lub tswb tsis tseeb hauv kev tsim khoom.
(2) Breakout kwv yees yog ua raws li kev hloov pauv ntawm cov cua sov hauv pwm.Txoj kev yooj yim tshaj plaws thiab ncaj qha yog ntsuas qhov kub ntawm qhov sib txawv ntawm qhov dej nkag thiab qhov hluav taws xob kub ntawm cov pwm txias dej, tab sis txoj kev no feem ntau ua yuam kev.Nws yog siv los ntsuas kub hloov mus rau kwv yees breakout.Yog hais tias lub tshav kub hloov mus rau ib chav tsev ntawm cov pwm yog siv rau breakout kwv yees, tus neeg teb xov tooj tuaj yeem ua qhov tseeb raws li cov cua sov hloov mus rau ib chav tsev, xws li txo cov duab nrawm, ua kom cov duab nrawm nrawm, nres pouring, thiab lwm yam.
(3) Copper phaj thermocouple ntsuas thiab kev twv ua ntej tawg.Qhov tseeb ntawm breakout kwv yees ntawm tooj liab phaj thermocouple ntsuas yog qhov siab.Lub breakout kev kwv yees qhov system ntawm high-tech yog tsuas yog raws li thermocouple breakout kwv yees.Nws txoj haujlwm ua haujlwm yog txhawm rau txhim kho ntau yam thermocouples ntawm cov pwm.Tus nqi kub ntawm cov thermocouples yog kis mus rau lub computer system.Yog tias nws tshaj tus nqi uas tau teev tseg, nws yuav muab lub tswb, thiab cia li siv cov kev ntsuas sib xws lossis cov neeg ua haujlwm coj cov haujlwm sib xws kom tsis txhob tawg.Txoj kev no muaj lub luag haujlwm ntawm kev kwv yees kev sib koom ua ke, tawg tawg, slag suav nrog kev tawg, slab kev nyuaj siab thiab pom qhov muag pom kev ruaj khov ntawm slab plhaub hauv pwm.Nws cov ntaub ntawv yog muab tso rau hauv lub slab zoo kwv yees qhov system.
