Regarding.

Recently, in various industrial fields including foods, a wide variety of techniques have been applied in which a gas is dissolved in a liquid at a high concentration and the gas is left as bubbles, destroyed or floated.

Bubbles are used to clean the surface of semiconductors, and in the environmental field, buoyant bubbles are used to remove suspended matter in wastewater.

As a bubble generation method for industrially utilizing bubbles, mechanical vibration is applied to the liquid using ultrasonic waves to generate bubbles, or the impeller is rotated at high speed while injecting gas to make large bubbles finer. An ultra-high-speed swirling method that is formed to break is used, or a method that regulates the flow of fluid to generate bubbles is used.

Of these, the method of generating bubbles using ultrasonic waves or the like has a drawback that the amount of bubbles can be controlled but the size of the bubbles cannot be controlled, and the cleaning process of the semiconductor wafer or the liquid crystal display device has a drawback. The method using an impeller can make fine bubbles generated in water, but it requires a large amount of electrical energy to rotate the impeller, and it is rotated at high speed. There is a drawback in that there is a problem in work safety because it must be done.

In addition, the high-speed rotation of the impeller destroys the structure of water and oxygen molecules, and metal particles are mixed in due to wear of the rotary blades, friction between the liquid and the impeller, and the rise in fluid temperature and alteration of the fluid due to heat generation of the drive motor.

FIG. 6 is a cross-sectional view of a coarse bubble generator which is a configuration of a bubble water production apparatus whose size can be adjusted, and FIG. 6 is one of the bubble water production apparatus whose size of fine bubbles can be adjusted according to the embodiment of the present invention. It is sectional drawing of the vortex generation type integration apparatus which is a structure.

Further, FIG. 7 is a perspective view illustrating a configuration in which a bubble size measuring device and a collecting unit are added to the bubble water production device capable of adjusting the size of fine bubbles according to the embodiment of the present invention.

Referring to FIGS. 1 to 7, the bubble water production apparatus capable of adjusting the size of fine bubbles according to the embodiment of the present invention includes a filter unit 10, a cooling unit 20, a water collecting tank 30, and a pumping unit 40. , The bubble water production tank 50, the gas supply unit 60, the coarse bubble generation device 70, and the injection unit 80 can be included.

More specifically, the filter unit 10 is for filtering the raw water supplied for producing bubble water, and the filter unit 10 can include a sand filter 12, a carbon filter 14, and the like.

Further, groundwater or the like may be used as the raw water, the sand filter 12 can remove suspended matter such as sand contained in the groundwater, and the carbon filter 14 is a colloidal substance that makes the groundwater turbid. It works to remove impurities such as milk fatty acids or polyphenols. Here, raw water is described as groundwater for ease of understanding, but it is not limited to groundwater, and may be a liquid such as groundwater, surface water, or tap water, and is a natural substance or natural substance. It may be a solution containing a chemical substance.

In the drawing, one sand filter 12 and two carbon filters 14 are shown, but the present invention is not limited to this, and the sand filter 12 and the carbon filter 14 may be provided in any other number. Good. That is, one or more sand filters 12 and one or more carbon filters 14 may be provided.

Needless to say, in addition to the sand filter 12 and the carbon filter 14, filters having other purposes may be provided.

The cooling unit 20 is connected to the filter unit 10 via a pipe, a hose, or the like, and may be formed to cool the raw water filtered by the filter unit 10 or the bubble water that is secondarily circulated. This is to maintain a temperature suitable for producing bubble water, and the cooling unit 20 is formed so as to maintain the temperature of the raw water or bubble water flowing through the cooling unit 20 at a temperature close to 0 ° C. in a liquid state. It can be maintained, preferably around 5 ° C.

Maintaining the temperature inside and outside about 5 ° C. is to increase the dissolution rate of the gas, that is, the ratio of bubbles remaining, and the lower the temperature, the more the gas becomes more soluble in raw water or bubble water, and the bubbles become more soluble. Residuality can be high. At this time, it is preferable to reduce the temperature to the maximum to increase the solubility of the gas to the maximum. However, when the fluid solidifies, the fluid becomes impossible to flow and the environment becomes an environment in which the gas is not dissolved. By adjusting the temperature inside and outside about 5 ° C., which is a temperature close to ° C., the solubility of the gas can be maximized and the solidification of raw water or bubble water can be prevented.

On the other hand, in the above, the cooling temperature is described as about 5 ° C. inside and outside as a preferable form, but the temperature range for forming the liquid 0 ° C. can be adjusted by ambient pressure or the like, so that the temperature range is not necessarily limited. It can be set freely in the range of 1 to 10 ° C. where the raw water or bubble water is not cooled.

The water collection tank 30 is a tank for collecting cooled raw water or bubble water, and the cooled raw water or bubble water is temporarily stored in the water collection tank 30 before being transmitted to the bubble water production tank 50. obtain. At this time, the inside of the water collecting tank 30 may be simply formed as an empty space, but as shown in FIG. 4, a funnel-shaped rotational force guiding device 32 may be installed.

The funnel-shaped rotational force inducing device 32 is configured to generate a rotational force in the flow of the liquid flowing into the water collecting tank 30, and the bubble water whose bubble size is adjusted first is the water collecting tank. After passing through 30, the contact area between the gas and water in the bubble water becomes wider, and by increasing the mixing force between the two, the undissolved gas can be dissolved, the residual efficiency can be increased, and the residual efficiency can be increased. In the case of bubbles formed to be excessively coarser than the size required for Pulse injection, there is an advantage that the quality of bubble water can be improved by quickly removing the bubbles from the water.

In order to maximize the effect of the rotational force guiding device 32 as described above, the pipe connecting the cooling unit 20 and the water collecting tank 30 is connected to the upper part of the water collecting tank 30 (hereinafter, "upper pipe"). The pipe formed so as to be drained from the water collecting tank 30 is preferably connected to the lower part of the water collecting tank 30 (hereinafter, referred to as “lower pipe”).

That is, the bubble water whose bubble size is first adjusted may be configured to descend through the upper pipe 34 and be discharged through the lower pipe 36 via the rotational force guiding device 32.

Further, the end portion of the upper pipe 34 connected to the water collecting tank 30 may be formed in the form of a Venturi pipe 34a. This is to increase the flow velocity at the end of the upper pipe 34 so that the rotational force can be easily generated by the rotational force guiding device 32.

Further, the end portion of the upper pipe 34 may be formed so as to project in a “┐” shape, and at this time, project so as to bend laterally at an angle of about 45 ° and eject toward the rotational force guiding device 32. This is to generate a rotational force, and it is considered that the rotation may not be easy when the vehicle descends vertically or is ejected horizontally.

The bubble water that recirculates due to the structure as described above has a high gas dissolution rate, can eliminate unstable coarse bubbles, and can further improve the quality of the bubble water.

The pumping portion 40 is connected to the water collecting tank 30 and may be formed so as to supply raw water or secondary circulating bubble water to the bubble water production tank 50. For this purpose, the pumping section 40 may be connected to the bubble water production tank 50.

At this time, the pumping unit 40 may be provided with three pressure pumps for continuously generating bubble water, but this is exemplary and not limited.

Further, in order to include the three pressure pumps as described above, the pumping portion 40 can form a throttle pipe in which a large number of flow paths intersect, and a valve such as a solenoid valve is formed in each pipe. It goes without saying that the flow of raw water or bubble water can be regulated.

Also, the pressure range of the pressure pump can be formed in 0.1-200 bar. In the present invention, the pressure range can be freely set within the above range depending on the size of the bubbles to be adjusted.

On the other hand, in order to prevent a water hammer phenomenon, each pipe of the pumping portion 40 may have a taper formed outward so as to reduce the pressure on the inner surface on the end side of the pipe connected to the pressure pump. Good.

The bubble water production tank 50 can be connected to the pumping unit 40 as a tank for producing bubble water, and can be connected to the gas supply unit 60 to receive gas supply. As a result, the bubble water production tank 50 can produce bubble water in the tank by receiving the supply of raw water from the pumping unit 40 and the gas supply from the gas supply unit 60.

At this time, the supplied gas may be one target gas of oxygen, hydrogen, carbon dioxide and ozone, or may be a mixed gas of these target gases, and depending on the supplied gas, oxygenated water, Bubble water such as hydrogen water, carbon dioxide water, or ozone water can be produced. However, the supply gas is exemplary and not limited to oxygen, hydrogen, carbon dioxide and ozone.

That is, when the raw water is supplied into the bubble water production tank 50 via the pumping unit 40, the target gas is supplied into the raw water together with the air, so that the bubble water such as oxygen water, hydrogen water, carbonated water or ozone water is supplied. Can be manufactured.

On the other hand, the bubble water production tank 50 may be made of a stainless steel material in order to maintain a constant pressure.

Further, the bubble water production tank 50 can form a recovery pipe 90 connected to the cooling unit 20 at the lower end portion. This is to refine the coarse bubbles of the bubble water in which the coarse bubbles are formed via the coarse bubble generation device 70 described later, and recirculate the coarse bubbles to the injection unit 80 described later via the recovery pipe 90.

At this time, the coarse bubble generator 70 is the raw water or bubble water that flows with the supplied gas. A gas-liquid mixing section 73 in which the liquid is mixed may be further contained in the upper end of the particle crushing section 71, and the gas is added to the raw water or bubble water to be flowed by measuring the size or amount of bubbles in the bubble water to be flowed. It may be formed to supply more.

Further, in the coarse bubble generator 70, a liquid adjusting unit (not shown) that controls the flow rate and flow velocity of the flowing liquid (raw water or bubble water) and a gas supply unit 60 are connected to the coarse bubble generating device 70. Occasionally, a gas adjusting unit (not shown) for adjusting the flow rate and flow velocity of the gas may be further provided, or an accelerating unit 76 may be formed at a connecting portion connected to the particle crushing unit 71, and the accelerating unit 76 may be formed.

The coarse bubble generator 70 is not limited to being connected to the water production tank 50, and may be connected to the water collection tank 30.

When the coarse bubble generator 70 is connected to the water collecting tank 30, the size of the primary bubbles is adjusted to adjust the size of the bubbles in the bubble water to be formed, and when the coarse bubbles of the bubble water are secondarily circulated, the size of the bubbles is adjusted to a smaller form. can do.

Can be made to be ejected as a fine spherical droplet when it circulates again in the injection unit 80 after the generation.

At this time, when the circulating bubble water is ejected as fine spherical droplets, it contains coarse bubbles, and a discontinuous section of the bubble water is generated, so that the bubble water is ejected in a pulse shape.

This is characterized in that the coarse bubbles are dispersed and the dispersion force is momentarily increased so that they can be mistized into smaller nano-sized fine particles. As a result, the fine spherical droplets of mistized nanoparticles increase the contact area with the gas at the time of injection, maximize the solubility, and produce fine spherical droplets in which a high concentration of gas is dissolved. After that, the fine spherical droplets in which a high-concentration gas is dissolved fall into the manufacturing tank, and bubble water in the form of fine bubbles is formed.

That is, the present invention has the efficiency that the miniaturization of bubble water can be maximized.
