簡易に調節できることなどが望まれる。 Means for atomizing and vaporizing organic solvents such as alcohol can be effectively used when feeding the organic solvent as vaporized fuel into the combustion chamber of an internal combustion engine or other combustion chambers. In this case, it is desirable that the spray vaporizer has a simple structure, consumes very little power, can spray the supplied liquid as a mist with an averaged fine particle size, and can easily adjust the injection amount. It can be done.

である。 In order to meet these demands, the present invention utilizes corona discharge to atomize organic solvents, resulting in a simple structure that does not require mechanical means, and enables operation with low power consumption. By considering the structure of the tip of the tube that supplies the solvent, we have developed an atomization method that explosively disperses the supplied liquid into a mist with an averaged fine particle size, and the amount of injection can be easily adjusted. This is what we provide.

る。 That is, the method of the present invention provides a porous member having a large number of micropores at the tip of an electrically conductive cylindrical tube that also serves as an electrode and is disposed on the central axis of a ring-shaped electrode.
The organic solvent is supplied from the cylindrical pipe through the porous member while a DC high voltage is applied between both electrodes, thereby explosively dispersing the supplied liquid into a mist having an average fine particle size. It is something to do.

すると、以下に詳述するように、有機溶剤の噴霧
を得ることができる。 To explain more specifically, as an example, as shown in FIG. 1, an electrically conductive cylindrical pipe 1 is used as a supply pipe for an organic solvent such as alcohol, and a porous member having many micropores at its tip is used. The metal tube 2 is fitted, the tip is closed with a lid 3, and this is placed on the center axis of the ring-shaped electrode 4 as one electrode, and the cylindrical tube 1 is grounded and the ring-shaped electrode 4 is Connect to voltage power supply 5. Then, with a DC high voltage applied between both electrodes, the cylindrical pipe 1 is
When the organic solvent is supplied through the porous metal tube 2 from the porous metal pipe 2, a spray of the organic solvent can be obtained as described in detail below.

を起こし、周囲に対向配置されたリング状電極４
に向つて平等な分布で分散する。 That is, the organic solvent supplied from the tube 1 is as follows:
If it is a dielectric liquid, a flow phenomenon occurs under the influence of an electric field, increasing the flow rate from the porous metal tube 2, and at the same time, repulsion occurs between molecules due to ionization of molecules inside the droplet, and this mutual repulsion occurs. When an optimal electric field is applied by
distributed in an even distribution toward .

ことができるが、上記ポーラスメタル管２を設け
ることにより、供給流体を加圧して供給すること
もでき、その供給圧力によつて液体の供給量を調
節することができる。 In this case, the flow phenomenon described above significantly accelerates the outflow of the supplied liquid from the porous metal tube 2. Therefore, even if the porous metal tube 2 having a large number of micropores is provided at the tip of the cylindrical tube 1, the supplied liquid Although it is possible to atomize by free fall or forced supply at low pressure, by providing the above-mentioned porous metal pipe 2, the supply fluid can also be supplied under pressure, and the supply amount of the liquid can be controlled by the supply pressure. Can be adjusted.
さらに、上述したように筒管１の先端に多数の
微細孔を有するポーラスメタル管２等の多孔部材
を設けると、液滴が多数の小孔から微細な粒とな
つて霧状に噴出し、それにより供給液体を平均化

化することができる。 Furthermore, if a porous member such as the porous metal tube 2 having a large number of micropores is provided at the tip of the cylindrical tube 1 as described above, droplets will be ejected as fine particles from the large number of small holes in the form of mist. As a result, the supplied liquid can be explosively dispersed and atomized into a mist having an average fine particle size.

低く制限されるなどの問題があるが、上記多孔部
材を設けた場合には、比較的広い流量範囲におい
て有効な噴霧化を行うことができ、それによつて
広範囲な流量調節を行うことが可能となる。 For example, when supplying liquid directly from the tip of a cylindrical pipe without a porous member, such as the above-mentioned porous metal pipe 2, it is necessary to increase the voltage between the electrodes or apply pressure to the supplied liquid. However, when the above-mentioned porous member is provided, effective atomization can be achieved over a relatively wide flow range. This allows a wide range of flow adjustments to be made.

ポーラスメタルまたはセラミツクス等の多孔体７
を筒管１の先端に嵌着したり、あるいは、同図
ｄ，ｅに示すように、筒管１の先端に金網８等を
取付けることによつて構成することもできる。 In addition, when providing a porous member having a large number of micropores at the tip of the electrically conductive cylindrical tube 1, it is necessary to provide not only the porous metal tube 2 but also the cylindrical tube 1 as shown in FIG. 2a. By attaching a porous spherical member 6 to the tip, as shown in FIGS. b and c,
Porous body 7 such as porous metal or ceramics
It can also be configured by fitting the pipe into the tip of the tube 1, or by attaching a wire mesh 8 or the like to the tip of the tube 1, as shown in d and e of the figure.

こし、ポーラスメタル管２からの流出が有効に促
進されることになる。 In particular, when the porous body 7 made of porous metal or ceramics is used, the pore diameter can be reduced to about several micrometers, thereby making it possible to eject the supplied liquid as extremely fine droplets. In this case, the supplied liquid causes a flow phenomenon under the influence of the electric field, and its outflow from the porous metal tube 2 is effectively promoted.
さらに、上記有機溶剤としては、それが誘電液
体の場合について上述したが、例えばアルコール
等の中間的誘電率をもつ液体またはアルコールと
低誘電率をもつ水を混合したアルコール水（例え
ばアルコール20％、水80％）等の分散噴霧をも行
うことが可能である。 Furthermore, as for the above-mentioned organic solvent, although the case where it is a dielectric liquid was described above, for example, a liquid with an intermediate dielectric constant such as alcohol, or an alcoholic water that is a mixture of alcohol and water with a low dielectric constant (for example, 20% alcohol, It is also possible to perform dispersion spraying of water (80% water), etc.

20kvの電圧を印加するのが適切である。 In this case, the supplied liquid causes a flow phenomenon as the applied voltage increases, simultaneously generating droplets, and then explosively dispersing the droplets to form atomization, but the dispersion angle changes as the applied voltage increases. Therefore, it increases and reaches its maximum just before the discharge current shows a sudden rise. Therefore, in the case of the above example, 10~
It is appropriate to apply a voltage of 20kv.

ように構成している。 The vaporizer shown in FIG. 4 is one in which the method of the present invention is applied to supply vaporized fuel to a combustion device such as an internal combustion engine. Separately from the air intake port 11, a second supply pipe 12 which also serves as a needle electrode for supplying a second fuel such as alcohol is installed at a position close to the air intake port. A high voltage is applied between the supported ring-shaped electrode 14 and the second supply pipe 12 by a high voltage DC power supply 15.

送り込まれる。 Therefore, the second fuel flowing out from the second supply pipe 12 is atomized and dispersed according to the electric field, and is vaporized in the electric current (arrow) flowing into the vaporizer, and then flows into the supply pipe 1.
It is sent into the combustion chamber in a mixed vaporized state with the fuel ejected from 1.
なお、上記供給管１１を設けなくてもよく、こ

供給される。 Note that the supply pipe 11 may not be provided, and in this case, only the fuel from the supply pipe 12 is supplied to the combustion chamber.

とができる。 In such a fuel vaporizer, it is also possible to supply alcoholic water as described above from the second supply pipe 12, thereby simultaneously adding water to the combustion chamber to improve the combustion state. It can be carried out.
以上に詳述したところから明らかなように、本
発明の方法によれば、機械的駆動部分のない極め

より燃料等を拡散噴霧化することができる。 As is clear from the above detailed description, according to the method of the present invention, it is possible to diffuse and atomize fuel etc. with an extremely simple structure without mechanically driven parts and with extremely low power consumption.

の調節も容易に行うことができる。 In addition, since a porous member with a large number of fine holes is provided at the tip of the cylindrical tube that also serves as an electrode, the supplied liquid can be explosively dispersed into a mist with an averaged fine particle size, and the injection amount can be easily adjusted. I can do it.
