Abstract

This invention relates to jet apparatuses for conducting processes in liquid and gaseous-DIx media and provides an increase in the efficiency of mixing media of various densities. Swirl mixer includes a housing 1 with channels 2 of the inlet and outlet 3 of the medium, communicated with each other through the vortex chamber. The injector is installed in channel 2, and a piezo-electric heater is installed at the outlet of channel 2. The injector mixing chamber is installed to form between its outer surface and the wall of the channel 2 a supply with a heater 7 of the annular channel, which communicates the receiving chamber 10 of the injector with the vortex chamber. The medium entering the vortex chamber deforms the plate heater. As a result, the potentials of the electric current accumulate in the piezoelectric elements, which provide heating of the medium and reducing its viscosity. 1 il. (L

Description

 .one

This invention relates to chemical engineering, in particular to inkjet apparatus for wire and

processop in liquid and gaseous

environments.

The purpose of the invention is to increase the efficiency of mixing media of various densities.

The drawing shows a vortex mixer.

The mixer comprises a housing 1 having channels for supplying 2 and withdrawing 3 of the medium, communicated with each other by means of a vortex chamber 4 having a toroid shape. In the supply channel 2, an injector is installed, consisting of a nozzle 5 and a mixing chamber 6. At the outlet of the supply channel 2, an apastine piezoelectric heater 7 is installed, made in the form of lamellar rings, insulated by a heat line 8 from a copper plate or foil.

The injector mixing chamber 6 is installed to form an annular channel 9 between its outer surface and the wall of the channel 2 with the heater 9. Channel 9 informs the receiving chamber 10 of the injector with the vortex chamber 4,

The device works as follows.

The pre-mixed pressurized working fluid is fed through

the nozzle 5 into the vortex chamber. 4, where, having made a vortex motion, it hits the heater 7, deforming it flat. In the piezoelectric elements, the potentials of the electric current are accumulated, resulting in spark pressure and heat emission, which is transmitted through the heater 7 to the working medium current. As a result, it heats up and decreases its viscosity. The heated flow is sucked into the injection chamber and begins to counter-rotate the rotary joint around the injector and the vortex chamber 4. The quality of the sweeping of the working medium is twisted.
