5000L High Pressure Homogenizer

Nws muaj ob hom homogenizers : lub siab shear homogenizers thiab siab siab homogenizers . Hauv cov khoom ua kua tawm, cov tib neeg ua rau lub ploj zuag ntawm cov theem ntawm cov dispersed los yog cov qoob loo yog lub zog qeeb thiab siab. Qhov kev tshawb fawb ntawm cov kev ua qias neeg thiab kev quab yuam yog ua rau cov dej khov, cov cua thiab cov teebmeem cavitation. . Cov kab mob laminar flow ua rau shearing thiab elongation ntawm tus txheej txheem dispersed lossis mob; cov nyhav dej huam tuaj ua rau random deformation ntawm cov kev ua rau cov dispersed theem los yog cov mob nyob rau hauv cov kev hloov siab fluctuation; cov nyhuv cavitation yog ua rau cov me me npuas los ua kom tawg mus ua kom poob siab. Thiab ua rau muaj kev ntxhov siab.

(1) High shear homogenization mechanism

Tam sim no, kab ceev ntawm homogenizer shear feem ntau siv nyob rau hauv Suav teb yog 10 ~ 25 m / s, uas proves tias homogenization nyhuv tsis zoo tagnrho. Homogenizer qib high-shear yog hais txog ib homogenizer shear nrog ib txoj kab tawm ntawm 40-66 m / s. Cov haujlwm ua haujlwm tseem ceeb yog cov theem ib theem lossis ib theem ntawm cov theem sab stator uas hloov, thiab txhua theem muaj ntau txheej ntawm lub nplhaib sib txawv. Ua hauj lwm txoj cai: Lub rotor muaj kev sib hloov siab ntawm cov hniav los ua kom muaj zog centrifugal force teb, thiab ib qho muaj zog tsis zoo siab yog tsim hauv nruab nrab ntawm lub rotor. Cov kua (kua-kua los yog cov kua-kua sib tov) yog tshem tawm ntawm qhov chaw ntawm tus stator thiab rotor nyob rau hauv qhov kev txiav txim ntawm lub zog centrifugal. Cov khoom diffuses los ntawm lub chaw mus rau lub periphery. Thaum lub sijhawm mus rau qhov chaw nyob, qhov khoom yog thawj zaug los ntawm cov hniav, thiab txav ntawm qhov chaw nruab nrab ntawm lub ntsej muag kawg thiab sab hauv sab hauv ntawm lub stator nplhaib iav, thiab pib nkag mus rau hauv lub nplhaib puab thiab cov tsau yog nqaim. Nyob rau hauv qhov sib txawv me me, nyob rau hauv qhov kev txiav txim ntawm mechanical force thiab hydrodynamic nyhuv, ib tug loj shear, txhuam, qhov cuam tshuam thiab kev sib tsoo thiab kev sib txhuam ntawm cov ntaub ntawv yog generated los ua kom puas rau cov dispersed theem particles los yog mob. Raws li txoj kev khiav ntawm txoj hlua khau uas maj mam nce tawm ntawm lub nplhaib rau sab nrauv, qhov chaw ua haujlwm zoo me ntsis zoo dua, thiab cov khoom yog crushed ntau dua los ntawm qhov kev txiav txim ntawm shearing, txhuam, qhov cuam tshuam thiab kev sib tsoo thaum lub sij hawm sab nrauv zog. Lub finer nws yog, qhov ntau homogeneous lub emulsification yog achieved.

Tib lub sij hawm, hauv cheeb tsam tsis zoo siab ntawm lub chaw rotor, thaum lub siab yog qis tshaj qhov muaj qhov siab ntsub (lossis huab cua sib cais) ntawm cov kua, ntau tus npuas tsim tawm, thiab cov npuas muaj crushed nrog cov kua dej mus rau lub stator nplhaib iav lossis vau nrog lub siab ntxiv. . Thaum lub sij hawm ntawm lub cev qhuav dej, lub microjet yog tsim los ntawm qhov chaw ntawm tus npuas. Lub dav hlau tshaj tawm yuav ncav cuag 100 m / s lossis txawm tias 300 tawm m / s. Tej yam quab yuam tsim los ntawm kev sib tw ntawm cov dej hauv siab, xws li P = ρCaC, qhov twg ρ yog kua. Ceev; Ca yog lub suab ntawm lub suab hauv cov kua; C yog qhov tshaj tawm ntawm cov microjet. Cia C yog 100 m / s, qhov ua rau lub ntsev tov yog ze rau ntawm 200 M Pa, uas yog cov nyhuv cavitation. Lub zog tsis muaj zog txaus yuav ua rau cov mos mos, cov khoom siv ib nrab zis, los yog cov khoom nplaum agglomerated uas yuav tsum tau muab pov tseg.

(2) Hom kev ua haujlwm siab siab homogenization

Homogenization kev siab siab yog siv cov kev kub siab ua kom muaj siab qis quab yuam thaum cov khoom ua kua ntws los ntawm lub voos nrawm ntawm kev kub ceev. Cov khoom ua kua yog cuam tshuam rau lub nplhaib hlau los ua kom muaj kev quab yuam muaj zog, thiab huab cua tau tsim los ntawm txoj kev poob siab thiab kev cia siab. Kev sib xyaw ntawm kev sib ntaus sib tua ntawm lub qhov thiab qhov zoo li, txheej txheem ntawm kev lag luam loj loj lossis tshem tawm ntawm cov khoom qub rau hauv cov dej ruaj ruaj ruaj khov lossis tshem tawm ntawm cov khoom. Thaum lub homogeneous khoom kis tau los ntawm qhov sib txawv ntawm qhov nruab nrab ntawm lub rooj zaum ntawm lub plhaub thiab lub nrig ntawm lub plhaub, qhov ndlwg yog nce mus txog 200-300 m / s nyob rau hauv ib qho tseem ceeb, uas ua rau lub siab loj kawg, thiab cov kua ua kom txaus thaum lub siab yog txo qis rau kev ua haujlwm kub. Nyob ntawm vapor siab (los yog kev sib cais ntawm huab cua), cov kua pib ua "kub npau npau" thiab sai "vaporizes", ua kom muaj ntau ntau npuas hauv. Cov kua uas muaj ntau cov micro-npuas ntws tawm mus rau ntawm lub qhov hluav taws xob, qhov ndlwg yog txo qis, thiab qhov siab nce. Thaum lub siab nce mus rau ib qho nqi, lub npuas nyob rau hauv cov kua dheev dheev tawg thiab re-condensations, thiab cov npuas yog generated thiab collapsed instantaneously. Lub teeb meem tshwm sim yog tsim. Cov phenomenon ntawm cavitation yog zoo li ib cov meriad ntawm tej yam me me tej tawg hem. Qhov mob siab khov ua rau lub zog ua rau muaj kev vibrations muaj zog. Tib lub sij hawm, nrog lub zog qeeb qeeb qeeb los ntawm muaj zog qaug zog, cov mos mos thiab ib nrab ntawm cov kua hauv cov kua muaj cov kab noj hniav thiab cua hlob. Lub zog qe yog sib xyaw ua ke los ua cov hmoov me me, thiab cov nyhuv ntawm cov nyhuv cavitation yog qhov loj. Cov hmoov me me ces tom qab ntawm kev kub ceev mus rau lub nplhaib thiab ntxiv pulverized thiab dispersed.

(3) Kev sib piv thiab kev tshuaj ntsuam

Raws li cov saum toj no kev tshawb fawb, tus qauv siab-shear homogenizer yog vim yog lub siab ua haujlwm tshwm sim los ntawm kev sib tsoo ntawm kev sib tsoo ntawm tus stator thiab rotor, thiab cov khoom siv uas tau muab faib, ua kom zoo thiab homogenized nrog cavitation muaj zog. Lub siab homogenizer siab tsuas yog los ntawm kev muaj zog thiab txaus cavitation thiab kiv cua los ntawm lub tshuab ua kua siab kom tawg rau hauv cov dej hauv cov theem ntawm lub cev kom tiav homogeneity. Nws tsis yog yooj yim to taub tias lub tshuab high-pressure homogenizer yog tsim rau cov kev kho mob ntawm cov mos mos thiab cov mos muag muag muag vim cov cavitation tsis tshua muaj zog heev. Nws pom tau hais tias qhov zoo tshaj plaws ntawm cov qoob loo ntawm cov roj pulverization yog txav quab yuam thiab kev sib tsoo quab yuam. Thaum lub cev kub, qhov feem quab yuam yog lub hwj chim tsis muaj hwj chim, thiab lub tshuab qes qes homogenizing tuaj yeem tsim muaj zog shearing thiab sib tsoo nkaus ntawm cov khoom. Vim li no, lub siab qis homogenizer zoo tshaj rau kev kho cov phom muaj ntau dua los yog muaj kuab, yooj yim kom pom xim txheej, hnyav dua cov ntaub ntawv. Tam sim no, kab ceev ntawm homogenizer shear feem ntau siv nyob rau hauv Suav yog feem ntau 10 mus rau 25 m / s. Xyaum tau muaj pov thawj tias nws cov homogenization nyhuv tsis zoo tagnrho. Lub siab shear homogenizer hais txog ib tug shear homogenizer nrog ib tug linear tshaj tawm ntawm 30-40 m / s. Cov haujlwm ua haujlwm tseem ceeb yog 1 lossis ntau theem ntawm kev sib tshuam ntawm cov tsheb khiav, thiab txhua theem ntawm tus stator muaj ob peb txheej ntawm lub nplhaib sib txawv.
