Ultrasonic yog ib daim ntawv thov ntawm cov khoom siv sonochemical, uas tuaj yeem siv rau kev kho dej, khoom-kua dispersion, de agglomeration ntawm cov khoom hauv cov kua, txhawb cov khoom-kua cov tshuaj tiv thaiv thiab lwm yam.Ultrasonic disperser yog txheej txheem ntawm dispersing thiab rov sib sau ua ke hauv cov kua los ntawm "cavitation" nyhuv ntawm ultrasonic yoj hauv cov kua.

Lub ultrasonic disperser yog tsim los ntawm ultrasonic co qhov chaw thiab tshwj xeeb tsav tsheb fais fab mov rau ultrasonic.Cov khoom siv ultrasonic vibration feem ntau muaj xws li high-power ultrasonic transducer, horn thiab lub taub hau (hloov lub taub hau), uas yog siv los tsim ultrasonic kev co thiab xa cov kev co zog rau cov kua.Thaum ultrasonic kev co yog kis mus rau cov kua, vim lub siab siv lub suab, ib tug muaj zog cavitation nyhuv yuav zoo siab rau hauv cov kua, uas ua rau ib tug loj tus naj npawb ntawm cavitation npuas nyob rau hauv cov kua.Nrog rau tiam thiab tawg ntawm cov cavitation npuas no, micro dav hlau yuav raug tsim los rhuav tshem cov kua thiab cov khoom loj.Nyob rau tib lub sijhawm, vim qhov kev vibration ntawm ultrasonic, cov khoom thiab cov kua sib xyaw ua ke ntau dua, uas txhawb nqa cov tshuaj lom neeg feem ntau.

Yog li cas ultrasonic disperser ua haujlwm li cas?Cia peb coj koj los nkag siab:

Qhov qis ntawm cov phaj dispersion ntawm qhov ntsuas yog nyob rau hauv lub xeev laminar ntws, thiab cov slurry txheej nrog cov nqi sib txawv diffuse ib leeg los ua lub luag haujlwm hauv dispersion.Nws muaj ntau yam haujlwm, xws li kev nqa hydraulic, 360 degree kev sib hloov, kev tswj ceev nrawm thiab lwm yam.2-4 lub thawv tuaj yeem teeb tsa tib lub sijhawm.Lub hydraulic lifting stroke ntawm 1000mm thiab 360 degree rotation muaj nuj nqi tuaj yeem ua tau raws li ntau lub hom phiaj ntawm ib lub tshuab.Nws tuaj yeem hloov pauv ntawm ib lub tog raj kheej mus rau lwm qhov hauv lub sijhawm luv luv, uas txhim kho kev ua haujlwm zoo thiab txo qis kev siv zog.

Lub zog centrifugal muaj zog cuam tshuam cov ntaub ntawv los ntawm radial kev taw qhia mus rau qhov nqaim thiab meej qhov sib txawv ntawm stator thiab rotor.Nyob rau tib lub sij hawm, cov ntaub ntawv yog preliminarily dispersed los ntawm tag nrho cov rog xws li kua txheej kev sib txhuam, centrifugal extrusion thiab hydraulic cuam tshuam.Nws tuaj yeem shear, crush, cuam tshuam thiab disperse cov ntaub ntawv ntawm kev kub ceev, thiab ua tiav lub zog ntawm dissolution sai, sib tov, dispersion thiab refinement.

Ua kom cov slurry ntws nyob rau hauv ib tug dov annular flow thiab tsim muaj zog vortices.Cov khoom nyob rau hauv slurry nto ntog mus rau hauv qab ntawm lub vortex nyob rau hauv ib tug kauv zoo, tsim ib tug turbulent cheeb tsam ntawm ntug ntawm lub dispersion phaj ntawm 2.5-5 hli, thiab slurry thiab hais lus muaj zog sheared thiab cuam tshuam.Nws manifestation yog hais tias lub transducer tsiv rov qab mus rau hauv lub longitudinal kev taw qhia, thiab lub amplitude feem ntau yog ob peb microns.Xws li amplitude zog ceev tsis txaus thiab tsis tuaj yeem siv ncaj qha.

Kuv vam tias cov ntsiab lus saum toj no tuaj yeem pab koj nkag siab zoo dua cov cuab yeej.
