Title:
METHOD FOR GENERATING MIST AND MICROBUBBLES USING SURFACE ACOUSTIC WAVES AND DEVICE FOR GENERATING MIST AND MICROBUBBLES
Document Type and Number:
WIPO Patent Application WO/2010/150629
Kind Code:
A1
Abstract:
Provided are a method for generating mist and microbubbles and a device for generating mist and microbubbles that has a simple and small-sized structure and in which a wide range of liquid types are applicable and the stable generation of either mist or microbubbles or both is possible. In a main unit (1), a section of a piezoelectric substrate (2), which is equipped with a plurality of comb-tooth shaped electrodes (21) on the surface (S) thereof, is inserted into a liquid (10) in a manner such that the surface (S) intersects the mutual interface (10a) of a gas and the liquid (10), and surface acoustic waves (W) excited on the surface (S) by the electrodes (21) are transmitted along the surface (S) in a manner such that the surface acoustic waves are present above and below the interface (10a). The surface acoustic waves (W) generate mist (M) on the gas side above the interface (10a) and generate microbubbles (B) on the liquid (10) side below the interface (10a). Since the mist (M) and microbubbles (B) are generated by surface acoustic waves (W) instead of a mechanical operation such as the generation of a rotational flow, the mist (M) and microbubbles (B) can be stably generated in a simple and small-sized structure.
