Description

[Detailed description of the invention] This invention relates to a combustion device that atomizes and burns liquid/fuel using an ultrasonic vibrator, and has a simple structure that improves the mixing of mist and air. It is.

Referring to the figures below, reference numeral 1 denotes a cylindrical atomization chamber, an ultrasonic vibrator 2 is attached to the slit-shaped bottom, and a communicating discharge chamber 3 is formed at the top.

Reference numeral 4 denotes a liquid fuel supply port opened at the bottom of the atomization chamber 1, which is communicated with a fuel tank via an electromagnetic pump leveler, an electromagnetic valve, etc.

Reference numeral 5 denotes an introduction opening at the upper side of the atomization chamber 1 through which the accelerated flow from the blower 6 is introduced into the atomization chamber 1 .

A burner 7 communicates with the discharge chamber 3 through a guide pipe 8, and has a main body 7a having a doughnut-like planar shape and a semi-cylindrical cross-sectional top opening, and a burner 7 that closes the top opening of the main body 7a. The shape is reversed, and the slit flame lower, 7'...
It is composed of a head 7b having a large number of holes therein, and a heat-resistant filter 70 such as foamed sintered metal or wire mesh interposed between the main body 7a and the head 7b.

Reference numeral 9 denotes a semi-cylindrical rectifier plate installed vertically inside the atomization chamber 1, with one end 9' near the inlet 5 so that the accelerated flow from the inlet 5 swirls in one direction inside the atomization chamber 1. When it comes into contact with the atomization chamber 1 wall, the matching metal body is kept at a predetermined distance from the atomization chamber wall.

Thus, a fountain-shaped liquid column 10 is generated by the ultrasonic vibrator 2, and a mist is generated at the tip thereof.

On the other hand, an accelerated flow is introduced from the inlet 5, swirled in one direction by the rectifier plate 9, and mixed with mist. At step 70, large particles are screened out and only the ultrafine particles reach the flame lower ', 7', and are burned.

When it is burned, the combustion flame heats the filter 7C, so the Ikon Aiki is vaporized by the heat while passing through the filter 7C, thereby making combustion safer.

As described above, in the present invention, the accelerating air inlet 5 is provided on the side of the atomizing chamber 1, and the rectifying plate 9 is installed inside the atomizing chamber 1 so that the accelerating air from the inlet 5 swirls around the liquid column 10. , the mist generated from around the liquid column 10 is well mixed with air, and mixing of large droplets generated near the liquid column 10 with air is avoided. The air-fuel mixture is stably supplied to the burner 7 and can be completely combusted.

Further, in the present invention, since the burner 7 is provided separately from the atomization chamber 1 via the guide pipe 8, there is no risk of flashback combustion.

Claims (1)

[Scope of utility model registration request] An ultrasonic vibrator is installed at the bottom of the atomization chamber so that a liquid column is generated from the fuel in the atomization chamber, and accelerated air is introduced into the atomization chamber to remove the mist generated from around the liquid column by the vibrator. The atomization chamber is taken out from the atomization chamber and supplied to the burner, and an inlet for accelerating air is provided on the side of the atomization chamber, and the accelerating air from the inlet is rectified so as to swirl around the liquid column. A plate is provided in the atomization chamber, and a mixture of the liquid fuel mist produced by the ultrasonic vibrator and the accelerated air is supplied to the burner from a discharge chamber provided at the upper part of the atomization chamber through a guide pipe. This is an ultrasonic combustion device.
