ド4が密閉接合されている。The liquid supply pipe 1 is hermetically connected to a hole at the bottom of the side of the cylindrical container 6, and the air supply pipe 3 is hermetically connected to the hole (2) at the top of the side of the cylindrical container 6, so that they communicate with the inside of the cylindrical container 6. ing. The container bottom 9 is sealed with the lower surface of the cylindrical container 6, and an ultrasonic vibrator 2 integrated with a rubber sealing material is screwed into an opening hole 9a near the center of the container bottom 9 with the rubber sealing material sandwiched therebetween. There is. A spherical guide 5 is hermetically connected to the upper surface of the cylindrical container 6 so that the insides thereof communicate with each other. In addition, inside the cylindrical container 6, a honeycomb structure 7 having a large number of small holes 7a is arranged over the entire area of the ultrasonic vibrator 2 except for the upper inner part 8. 1 and is fitted and fixed on the side surface of the cylindrical container 6 so as to protrude above the liquid surface A. To explain this honeycomb structure 7 in more detail, its outer periphery is circular and its overall shape is cylindrical, but it has a circular hollow part in the portion corresponding to the upper inner part 8 of the vibrator. It has become. By providing a slight gap C between the bottom surface of the honeycomb structure 7 and the container bottom 9,
All the small holes 7a and the liquid supply vibrator 1 communicate with each other. In addition,

安定し、均一な霧化流になり霧化量をも増大することが
可能となる。The operation in the above configuration will be explained. The liquid is introduced into the cylindrical container 6 from the liquid supply vibrator 1 and the liquid level is kept constant.
The ultrasonic vibrator 2 is atomized by being energized from a circuit not shown, and the atomized droplets are guided out through the inside of the spherical guide 5 by the gas introduced along the air supply pipe 3 and the guide 4. . The liquid remaining from the liquid column 10 without being atomized falls into the large number of small holes 7a of the honeycomb structure 7 due to its own weight, but in this case, the liquid filled in the small holes 7a plays the role of a buffer, It becomes possible to prevent the liquid level in the upper interior 8 of the ultrasonic transducer 2 from shaking. For this reason, the liquid column 10 becomes stable and becomes a uniform atomized flow, making it possible to increase the amount of atomization.

い場合に比較して霧化量を20〜25%増大させること
ができた。By using an aluminum honeycomb having small holes 7a as shown in FIG. 2 as the honeycomb structure 7, it is possible to increase the amount of atomization under all conditions (4). For example, according to the inventor's experiments,
The honeycomb structure 7 has a height of 30 mm, an opening area of regular hexagonal small holes 7a of 23.4 wJ, and a thickness of partition walls 7b of 0.01 mm.
The gas flow rate was varied by using a liquid with a diameter of 21 mm, keeping the liquid temperature at 21°C, the liquid level height from the center of the vibrator 2 at 301 mm, and making the upper end of the honeycomb structure 7 about 5 g higher than the liquid level. As a result of conducting an experiment, it was found that when the honeycomb structure 7 was present, the amount of atomization could be increased by 20 to 25% compared to when the honeycomb structure 7 was not present.

である。FIG. 3 shows a second embodiment regarding the shape of the honeycomb structure 7, and in this example, the shapes of the large number of small holes 7C of the honeycomb structure 7 and the partition walls 7d that partition the small holes 7C are square. It's Toshide. The material of the partition wall 7d is the liquid supply vibrator 1.
Any material may be used as long as it is not corroded by the liquid introduced and does not absorb ultrasonic waves, such as metal or ceramic.

成するものであってもよい。Furthermore, although the small hole 7C in FIG. 3 is formed in a square shape and the small hole 7a in FIG. 2 in a hexagonal shape, the small hole shape may be circular as shown in the third embodiment in FIG. may also be the fifth
It may also be a polygon such as the hexagon (5) shown in the fourth embodiment of the figure. In FIGS. 4 and 5, 7e and 7g are small holes, and 7f and 7h are partition walls. Furthermore, the honeycomb structure 7 according to the present invention is not limited to one that forms a honeycomb shape by itself, but can also be one in which the inside of the cylindrical container 6 is partitioned with metal, ceramic, etc. to form small holes. It's okay.

きる。In these second, third and fourth embodiments, the small holes 7c, 7
In both e and 7g, the upper end surface and lower end surface are connected, and the lower end surface communicates with other small holes, so even if liquid falls into one small hole and shakes the liquid level, that small hole will not be filled. This liquid acts as a buffer, and hardly shakes the liquid level in other small holes. Therefore, the same effects as in the first embodiment can be expected.

効果をもたらす。The liquid introduced into the cylindrical container 15 from the liquid supply pipe 1 (
Liquid fuel (such as kerosene) is atomized by two ultrasonic vibrators 2 attached to the bottom part 9' of the container, and the atomized fuel droplets are introduced from two air supply pipes 3 to the cylindrical outside. The gas flowing into the container 15 along the flow guide 16 and the inner flow guide 17 is led out to the upper part of the container 15. The upper end of the container 15 is hermetically joined to the joint case 19 so as to sandwich the upper end of the sealing member 18 and the inner flow guide 17, and the upper end of the joint case 19 is connected to a plate 22 having a large number of small holes and the sealing member 2.
3 is sandwiched between the burner head 20 and the burner head 20 in a hermetically sealed manner. The atomized droplets led to the upper part of the container 15 pass through the inside of the joint case 19 (7) and a large number of small holes in the plate 22, and are led out through the slit provided in the burner head 20 to form a flame. 21 is a metal heat recovery plate made of aluminum, stainless steel, etc. that recovers the heat of the flame;
It is a partition plate for dividing. Inside the container 15, two honeycomb structures 70 have their upper end surfaces protruding between the lower end of the guide 17 and the liquid level A in a portion other than the upper interior 8 of the ultrasonic transducer 2, and the upper end surfaces of the honeycomb structures 70 protrude between the lower end of the guide 17 and the liquid level A. and the partial protrusions at the lower end of the honeycomb structure 70 are bonded and fixed to each other with a gap sufficient to allow communication between the small holes 70a (FIG. 7). A sealing member 12 is placed below the liquid level on the side wall of the container 15.
A temperature sensor 13 is provided via the seal member 2.
4 to the electric heater 26 (seventh) of the honeycomb structure 70.
The lead wire 25 in the figure) is taken out. Then, the detection signal of the temperature sensor 13 is manually inputted to the temperature controller 14, and the electric heater 2 of the honeycomb structure 70 is controlled according to this detection signal.
The liquid temperature is maintained at a constant value by intermittent power supply to 6. The specific structure (8) of the honeycomb structure 70 is as shown in FIG.
It is integrally molded in b. This is to prevent the heater 26 from coming into direct contact with the fuel, but the heater 26
As long as the surface of No. 6 does not rise above the flash point, the fuel may be heated directly. By raising the liquid temperature and keeping it constant in this manner, there is an advantage that the amount of atomization can be further increased in addition to the liquid level stabilizing effect provided by the honeycomb structure 70. In addition, in order to burn the atomized flow as a mixed gas, the honeycomb structure 70
The uniformity of the atomization flow by this method forms a stable flame, and the increase in the amount of atomization has the effect of enabling strong combustion with low electric power.

の適用の他に、空調用加湿器等にも適用できる。The present invention can be applied not only to liquid fuel combustion apparatuses such as the embodiment shown in FIG. 6, but also to air conditioning humidifiers and the like.

設置によって、超音波振動子上方の液面を安定化して、
霧化量を増大できるとともに、霧化量を安定させること
ができるという優れた効果(9)
がある。As detailed above, according to the present invention, the liquid level above the ultrasonic transducer is stabilized by installing the honeycomb structure,
There is an excellent effect (9) in that the amount of atomization can be increased and the amount of atomization can be stabilized.
