(54) ULTRASONIC HYDRODYNAMIC RADIATOR i

one

The invention relates to devices for the production of highly dispersed suspensions and emulsions and can be used in the enrichment of minerals, xHMiTic, food industry, as well as other sectors of the industry, where homogenization and mass transfer takes place.

On the main; th avt. swith No. 243984 is a known ultrasonic hydrodynamic emitter for producing aqueous mass emulsions consisting of a housing, an ejector, a tangential insert with a multiple-pass thread, a ring magnet and a cap with a nozzle.

The disadvantage of the apparatus is the low degree of dispersion of the emulsified liquid, as well as the slip through the apparatus of large (more than 100 microns) particles, which occurs when working with viscous substances. This is due to the fact that in this device there is no effective interaction of the flow flowing through the ejector in the axial direction and the vortex flow formed by multiple spiral cutting of the insert. Cavitation, which is the main dispersing factor in the production of small particles (units of microns) in size, is underdeveloped in this apparatus.

This device is ineffective if it is unacceptable for obtaining highly dispersed emulsions of viscous hardly emulsifiable substances.

The purpose of the invention is to increase the degree of dispersion of emulsions, especially highly viscous, hardly emulsifiable substances. 0 The goal is achieved by the fact that the ultrasonic hydrodynamic emitter according to ed. swith No. 243984 is provided with a glass coaxially mounted in the ejector with a tangentially located in its upper part of the nozzle, while the inner surface of the glass in the lower part is made with a screw thread, the direction of which is opposite to the direction of the tangential liner cutting.

The streams of dispersing fluid introduced from the high-pressure chamber and the vortex chamber through the cutting of the insert, twist tangentially and form the main vortex flow. Installing the glass coaxially to the ejector and connecting it to

The high-pressure chamber allows up to pbL11i spruce: n8 vodDy-gb into the whirlwind path to the auxiliary axial flow of the dispersing liquid (water). So between

 and a small turbine enclosure encloses a thin layer (fractions of a millimeter) of emulsifiable liquid, ejected through the ejector. The presence of a screw thread on the glass opposite to that of the LADA Sha ensures a twist of auxiliary hG1SHG 111Ga11H1SHi-ifpW

The spinning of the main vortex flow of the dispersing fluid and the thin annular emulsified liquid flow when ejected from the ejector is under the control of the SILON and auxiliary axial vortex flows of the dispersing agent that break a thin layer of liquid. In addition, this layer is additionally affected by acoustic oscillations, which arise in the interaction of two streams of dispersing liquid, and amp; kotopbie, enhance the effect of dispersion. Connecting the cup to the High-pressure chamber with a tube tangentially inserted into it

 It enhances the turbulence of the secondary flow of the dispersing liquid, thereby providing a high dispersing effect of the device proposed.

A device for producing a fine suspension and an emulsion works as follows.

The emulsifying fluid (water in the case of preparing aqueous emulsions) under pressure from the pump enters the high pressure chamber 3 and, through multiple spiral cutting of the liner 5, is tangentially fed into the vortex chamber 2, forming the main vortex flow. At the same time, from the high-pressure chamber 3, the emulsifying liquid through the tangential nozzle 10 enters the glass 9, which is in the form of auxiliary vortex flow, due to the internal screw thread at the outlet end of the glass, is introduced into the vortex chamber 2.

The emulsifiable LIQUID is supplied through a slot formed by the cup and the inner surface of the ejector tube 4, as well as

supplied to: the quality of the component mixed with

emulsifying liquid.

On a thin annular layer of emulsifiable liquid enclosed between the glass and the inner wall of the ejector, the opposite direction of the main And auxiliary vortex flows of the emulsifying liquid acts. In the vortex chamber 2, during the interaction of the main and auxiliary vortex fluid flows, turbulization and acoustic oscillations occur, contributing to the dispersion process. In the same chamber, the liquid is exposed to the magnetic force lines of the ring magnet b, which intensifies the emulsification process.
