することが知られている。 In the "fluid device" according to Japanese Patent Application No. 53-34869, a minute cavity opening toward the outlet is formed in the inner circumferential part of a hollow body equipped with an inlet and an outlet, and a small cavity is communicated with this cavity. When a pressurized fluid supply means is provided and fluid is supplied to this cavity at a predetermined pressure value, the flow velocity of the fluid supplied to this cavity reaches a sonic state, and a so-called sonic wall is formed on the discharge side of this fluid. The sonic wall excites the fluid in the gap, which turns into an extremely minute agitated flow that moves through the gap and is ejected. The fluid, which becomes a minute agitated flow at such a sonic speed, forms multiple sonic walls from inside the gap and is released toward the outlet side of the hollow body and spreads, and each sonic wall acts like a piston. to drive the fluid within the hollow body forward toward the outlet. The generation of fluid agitation in such minute voids is
It is necessary for the fluid to flow through the gap at the speed of sound, and for this reason, it is known that the pressure difference between the inflow side and the outflow side of the gap by the pressurized fluid supply means is 2:1 or more in the case of air. .

が知得されている。 As described above, by driving the fluid in the hollow body forward by a piston-like action, a large negative pressure is generated on the inlet side of the hollow body, and the inlet faces the liquid, for example, and air is used as the pressurized fluid. It is known that air and liquid are mixed and sprayed in the form of a mist from the outlet of the hollow body by force-feeding the liquid into a minute gap.

にある。 The present invention is based on the above knowledge, and by further improving the above "fluid device", gas-gas,
It is an object of the present invention to provide a device that more closely mixes two or more types of fluids such as gas-liquid, liquid-liquid, etc. and effectively injects them.

流体供給手段の圧力を設定してなる。 That is, in the fluid mixing and injection device of the present invention, a minute gap opening toward the outlet is formed in the inner peripheral surface of a hollow body having an inlet and an outlet, and the gap is used for supplying pressurized fluid. The tube communicates with the first fluid through a means, the inner circumference of the tube between the cavity of the hollow body and the inlet is formed into a bench lily shape, and a plurality of minute openings are formed in the neck of the bench lily. the opening is communicated with the second fluid by a pipe branched from the hollow body, the inlet is opened to the atmosphere, and the pressurized fluid is supplied to the cavity by the pressurized fluid supply means. The ratio of the inflow pressure of the first fluid to the outflow pressure of the first fluid discharged from the cavity into the interior of the hollow body is 2:
The dimensions of the void and the pressure of the pressurized fluid supply means are set so that the number of voids is 1 or more.

れて中空体の流出口から噴出される。 In this way, when the first fluid is released from the gap into the inside of the hollow body as a minute stirring flow, the fluid inside the outlet side of the hollow body acts like a piston as described above. Since the hollow body is driven forward, a large negative pressure is generated inside the inlet of the hollow body. Due to such a large negative pressure, a second fluid is sucked by a pipe branched from the hollow body, and this second fluid passes through a minute opening formed in the other inner circumference of the hollow body. The liquid is then finely divided and enters the hollow body, becomes a minute agitation flow, is intimately mixed with the activated first fluid, and is ejected from the outlet of the hollow body.
At this time, if the pressure difference between the negative pressure inside the hollow body and the inlet side of the minute opening is sufficiently large, the second fluid entering the hollow body through this minute opening reaches a sonic speed state, causing minute agitation. Since it enters the hollow body in an activated state as a flow, it is mixed extremely well with the activated first fluid as another minute stirring flow and is ejected from the outlet of the hollow body.

形成するようにすることである。 In order to generate a large negative pressure inside the hollow body when the second fluid enters the hollow body through the minute opening, in the present invention, a part of the inlet side of the hollow body is moved inward. The method is to squeeze it to form a bench lily shape, and form a plurality of the minute openings in the neck portion of this bench lily.

れ、水を極めて微小な粉霧状にして噴射する。 For example, in order to mix and inject air and water using the fluid mixing and injection device of the present invention having the above structure,
The free end of the pipe 13 branched from the second short pipe 2 may be inserted into the water tank 15, and the air compressor 8 communicated with the third short pipe 7 may be driven. This compressor 8 has sufficient ability to create a pressure difference of 2:1 or more between the inflow side and the outflow side of the gap 5, so that the pressure on the outflow side of the gap 5 is reduced to atmospheric pressure. (approximately 1Kg/cm 2 ), so if the compression pressure on the inflow side is 1Kg/cm 2 or more, the pressure difference between the inflow side (atmospheric pressure + 1Kg/cm 2 ) and the outflow side (atmospheric pressure) is 2:1. become. In order to generate such a pressure difference with a relatively small compressor, the size of the gap 5 should be made extremely small, and preferably the width of the gap between the short pipes 1 and 2 should be reduced.
It should be 0.2mm or less. In this way, the void 5
When a pressure difference of 2:1 or more occurs between the inflow side and the outflow side of the gap, the flow velocity of the air forced into the gap reaches the sonic speed, and a sonic wall is formed on the outflow side of the gap. Due to this sonic wall, the compressed air in the gap, especially on the outflow side, becomes a microturbulence and is activated and released into the first short pipe 1 in the form of a sound wave. The air in one short tube is pushed forward toward its outlet in a piston-like manner. Due to this action, a negative pressure is created on the inlet side of the second short pipe 2, and a large amount of air is sucked into the second short pipe at a high speed. At the same time, the water in the aquarium is sucked through the pipe 13 branched from the second short pipe 2, passes through the annular space 11, forms an extremely thin layer from the slit 10 of the bench lily member 9, and flows into the second short pipe. tube 2
is released into the center of the body. The water that has entered the central space of the second short pipe 2 flows at high speed to the outlet side of the first short pipe due to the action of driving the fluid in the first short pipe 1 in a piston-like manner. The mixture is mixed with the air released from the gap 5 of the first short tube, and is sprayed outside in the form of mist from the outlet. When this air and water are mixed, the air becomes a minute agitated flow from the minute gap 5 and is released into the first short tube. Since it persists for a predetermined period of time after being released, it mixes well with the water from the second short tube and sprays the water in the form of a very fine powder.

It has been described that the outlet side of the holder is made of a porous material with a minute pore size (12μ or less), and the bench lily member 9 or the slit 10 is made of the same porous material as described above. We focused on the fact that it has the property of strongly trapping liquids such as water due to its minute pore size, and does not easily release it in liquid form, but on the other hand, releases it easily in vaporized state. By using such a porous material, a part of the liquid passing through the slit 10 is vaporized here and intimately mixed with the fluid in the first short pipe 1, and is further vaporized at the first outlet side. A part of the liquid is vaporized by the porous material and then ejected, so that the mixed ejection of two types of fluids, especially liquid and gas, becomes even better.

されることが知得された。 FIG. 2 shows a second embodiment of the present invention, in which a pipe 1 is branched from a second short pipe 2.
This embodiment differs from the first embodiment in that the liquid 14 is communicated with a storage tank 15 through a pump 16, preferably a diaphragm pump. This pump 16 pressurizes a fluid, in this example a liquid 14, supplied through a branched pipe 13, so that when this liquid passes through a slit 10 of a bench lily-shaped member 9, its flow velocity reaches the velocity of sound. slit 10
This creates a minute stirring flow. Pump 1 for producing such stirring flow
The capacity of 6 has a correlation with the width of slit 10,
By reducing the width of the slit, a pump with a small capacity can be used. Preferably, the width (length of the short side) of the slit 10 is 0.2 mm or less, so that when the liquid is water, the inlet of the slit can be used. It has been found that by setting the pressure difference between the slit and the outlet to about 5:1 or more, a minute agitation flow is generated in the water when it passes through the slit, and the water is activated.

いものである。 In the case of the first embodiment, the bench lily member 9
The liquid flowing through the slit 10 in the second embodiment is supplied into the second short tube 2 in a layered form, whereas in the case of the second embodiment, the liquid flowing through the slit 10 becomes a minute stirring flow. It is supplied into the second short tube in the form of minute particles and in an activated state. For this reason,
Second, in the embodiment, the liquid that has become minute particles is further stirred and mixed closely with the air that has become a minute stirring flow in the first short tube 1, and is almost vaporized. is injected from the outlet. Therefore, the device of the second embodiment is particularly effective when liquid fuel is used as the liquid supplied to the second short pipe.

For example, the first short tube and the second short tube are constructed from one hollow tube, and the annular gap 5 is formed by press-fitting a ring-shaped member having a flange at one end into the hollow tube. can. Alternatively, instead of the bench lily-shaped member, a part of the second short pipe may be narrowed inward to form a passage that becomes gradually narrower from the left and right, and the slit 10 may be formed in the narrow part of this short pipe. good.
