1. Cov hauv paus ntsiab lus ntawm ultrasonic extraction thev naus laus zis
1.1 cavitation nyhuv ntawm ultrasound
Lub ntsiab cai tseem ceeb ntawm ultrasonic tseem ceeb roj extraction yog siv cov cavitation cov nyhuv ntawm ultrasound. Thaum high - zaus ultrasound (feem ntau 20 - 80kHz) propagates los ntawm cov kua nruab nrab, hloov siab thiab qis - lub siab ntsuas yog tsim. Hauv cov theem qis - theem siab, lub tshuab nqus tsev me me yog tsim hauv cov kua; Nyob rau hauv lub siab siab - theem siab, cov npuas vau sai, ua cov chaw ua haujlwm kub heev (li 5000atm). Qhov kev ua yeeb yam zoo no yog hu ua "Cavitation".
1.2 Lub luag haujlwm ntawm cavitation nyhuv hauv extraction
Lub zog poob siab heev thiab microjets tsim thaum cavitation npuas vau tau:
• rhuav tshem cov nroj tsuag ntawm phab ntsa qauv thiab nrawm nrawm ntawm cov ntsiab lus ntawm tes
• txhim kho kev hloov pauv loj thiab txhawb nqa cov kev nkag mus ntawm cov kuab tshuaj rau hauv cov nroj tsuag matrix
• Ua kom cov solubility thiab nrawm dua qhov sib txawv ntawm cov phiaj sib txuas rau hauv cov kuab tshuaj
• Txo cov extraction kub thiab tiv thaiv cov cua sov - Cov Cheebtsam rhiab
1.3 Tshuaj lom neeg cuam tshuam ntawm ultrasound - Pab extraction
Ntxiv rau lub cev teebmeem, ultrasound tseem tuaj yeem ntxias qee yam tshuaj lom neeg:
• Ua cov radicals dawb los txhawb txoj kev tso tawm ntawm qee yam
• Hloov pauv cov polarity ntawm cov kuab tshuaj kom nce cov solubility ntawm cov feem ntau
• Ua kom nrawm qhov kev siv dej hiav txwv hydrolysis kom tso cov khoom sib xyaw ua txhua yam
2. Cov lus sib xyaw ntawm cov ultrasonic tseem ceeb roj rho tawm cov khoom siv
Ib qho kev lag luam tiav - Qib Ultrasonic Qhov Tseem Ceeb Roj Cov Khoom Siv Roj Ntau Tshaj Plaws Cov Khoom Tseem Ceeb hauv qab no:
2.1 ultrasonic tshuab hluav taws xob
Raws li cov tub ntxhais ntawm lub system, nws yog lub luag haujlwm rau kev hloov lub zog loj rau hauv cov teeb meem hluav taws xob siab. Cov ntsiab lus tseem ceeb muaj xws li:
• Zaus deb: 20 - 40kHz (40kHz feem ntau siv rau cov roj ntxiv)
• Kev Tawm Tsam Fais Fab: 500W - 5000W Adjustable
• Cov mem tes tswj: Kev Ua Haujlwm / Sij Hawm Sijhawm Tuaj yeem teeb tsa
Kev tiv thaiv muaj nuj nqi: overload, overheating, luv nqi hluav taws xob
2.2 Transducer Los Ua Ke
Hloov ua ke lub zog hluav taws xob mus rau hauv tshuab kev co, feem ntau hauv ob hom:
Kev soj ntsuam kev kuaj mob raus dej dag: ntxig rau hauv lub nkoj tiv thaiv, lub zog muaj zog, haum rau kev ua me me
Lub cev trough: Ntau transducers raug teeb tsa nyob rau sab nraud phab ntsa ntawm lub cev trough, haum rau kev ua kom tsis tu ncua
2.3 Kev Txom Nyem
Xws li:
Siab Reactor (feem ntau 316L stainless hlau lossis titanium alloy)
Kev tswj qhov kub thiab txias (lub tsho txias lossis cov khoom siv cua sov)
Stirring ntaus ntawv (los txhim kho cov nyhuv sib xyaw)
Kev tswj siab siab (rau cov kev pab lossis cov kev pab cuam supercritical)
2.4 Kev sib cais thiab cov txheej txheem sau
Ncej - Extraction kev ua kauj ruam:
Zov - Theem Filtration ntaus ntawv
Centrifuge
Khoom Siv Hluav Taws Xob
Kev Ua Yeeb Yam Rov Los
2.5 Kev Tswj Tshuab Nkaus
Cov cuab yeej niaj hnub no feem ntau yog nruab nrog:
PlC lossis PC tswj interface
Tiag tiag - Sijhawm soj ntsuam ntawm cov tsis (kub, lub siab, hwj chim, thiab lwm yam)
Cov ntaub ntawv kaw thiab tshuaj ntsuam
Kev Nyab Xeeb Cuam Tshuam
