Description

  The present invention relates to a method and an apparatus for producing high-concentration gas-dissolved water such as high-concentration oxygen-dissolved water. And a method of using the produced dissolved water.

Conventionally, oxygen-dissolved water has been used in various applications, or sterilization or the like has been performed by blowing oxygen or air into the service water.
For example, the activated sludge method is conventionally known as a method for treating water to be treated such as sewage, food waste water, kitchen waste water, or industrial water, and in this activated sludge method, a treatment tank in which activated sludge, which is an aerobic microorganism, floats. By supplying wastewater and aeration with air, organic matter in raw water is oxidatively decomposed by the biological oxidation of activated sludge.

This air aeration is satisfactory because the oxygen concentration in the air is as low as about 20%, the air exists as bubbles, and the oxygen in the air cannot sufficiently contact the organic matter and microorganisms in the water to be treated. In many cases, sterilization efficiency cannot be obtained. In order to obtain sufficient sterilization efficiency, it is necessary to increase the size of the device, which not only increases the cost and installation area, but also requires advanced technology and complicated management for stable operation. There is also.
In order to solve such problems, a method has been proposed in which aeration target water collides with a collision surface to facilitate air entrainment (Patent Document 1). However, this method causes only a slight air entrainment and cannot sufficiently contribute to an increase in the aeration effect.

In the activated sludge method, in addition to increasing the size of the apparatus, an oxygen-enriched gas is used, or intense agitation is performed to promote contact between oxygen and the water to be treated. However, in the normal activated sludge method, the amount of water to be treated is enormous and the former method using expensive gas is not realistic. The latter stirring method also requires extra equipment, and the dissolution effect is not so much improved.
As described above, in the current activated sludge method, contact between oxygen during air aeration and microorganisms in the water to be treated is insufficient, and the treatment efficiency of the water to be treated can be greatly improved if the contact can be sufficiently performed. To rise.

In addition to the activated sludge method, dissolved water with high-concentration oxygen is widely used.
For example, in closed water areas such as lakes and dams, or rivers with a low flow rate, the water flow is stagnant and deterioration of water quality due to the propagation of various germs has become a major problem. When dissolved water of high-concentration oxygen is supplied to these water areas, the bacteria are killed by the sterilizing effect of oxygen, and a remarkable water quality improvement can be achieved. However, this remarkable improvement in water quality requires an enormous amount of high-concentration oxygen-dissolved water, and the water flow improvement using the high-concentration oxygen-dissolved water produced by the conventional method is virtually impossible. .
That is, as a conventional method for this purpose, there is a method in which bottom water is pumped by a pump installed on land, oxygen is dissolved by an oxygen dissolving device, and the generated dissolved water is returned to the bottom. However, even with this method, the oxygen dissolution is insufficient and a satisfactory sterilizing effect cannot be obtained, and the cost burden for pumping the bottom layer water is increased.

Fish live in water, and their ecology is greatly influenced by the amount of dissolved oxygen in the water. For example, it is known that when goldfish is bred with high-concentration oxygen-dissolved water, it grows to a size that cannot be considered by common sense. By analogy, it is thought that if high-concentration oxygen-dissolved water is used in the farm, the growth rate will be faster, and large fish and oysters will be cultivated. However, unlike the breeding of pets at home, the aquaculture farm requires an enormous amount of seawater and fresh water, so that it is not possible to obtain an effect that is commensurate with the cost of producing high-concentration oxygen-dissolved water.
In addition to oxygen-dissolved water, there are many uses for high-concentration gas-dissolved water. For example, nitrogen gas-dissolved water can be used for maintaining the freshness of fish and shellfish, and in this case as well, the effect becomes more remarkable as the concentration increases. Gases for which high-concentration dissolved water is desirable include nitrogen, hydrogen, ammonia, ozone, and the like.

Thus, there are many uses that require high-concentration oxygen-dissolved water, and various oxygen-dissolving methods have been proposed to meet the demand. However, in any case, oxygen having a satisfactory concentration could not be dissolved, and even if it could be made, it was too costly to adopt as a practical method. The same applies to the dissolution of other gases such as nitrogen.
Accordingly, the present invention provides a method and apparatus that can produce high-concentration gas-dissolved water relatively easily, and a method for treating water to be treated with the high-concentration gas-dissolved water obtained by this, particularly high-concentration oxygen-dissolved water. The purpose is to do.

The method of the present invention is a method for producing high-concentration gas-dissolved water, wherein the gas in the bubbles is dissolved in the water flow by colliding two or more water streams having bubbles, and the apparatus of the present invention comprises: The cylindrical body has a hemispherical shape, a small hole is formed in the center thereof, two supply pipes arranged in a straight line with the two small holes facing each other, and the two supply pipes An apparatus for producing high-concentration gas-dissolved water, comprising a water flow supply port for supplying a water flow having bubbles from the tangential direction, and a water flow outlet, formed on each base end side, and obtained thereby It is a processing method of the to-be-processed target water by the high concentration gas dissolution water produced. When the obtained high-concentration gas-dissolved water, particularly high-concentration oxygen-dissolved water, is passed through a high-temperature and high-pressure tankless line, the purpose of sterilizing microorganisms can be achieved more efficiently.
Furthermore, the present invention can be used to dissolve oxygen and / or ozone-containing gases in liquid fuels as well as water, by impinging two or more fuel streams having oxygen and / or ozone-containing gases. There is also provided a fuel supply and combustion method characterized in that the oxygen and / or ozone-containing gas is dissolved as fine bubbles in the fuel flow and then vaporized and supplied to an internal combustion engine for combustion.

The present invention will be described in detail below.
In the present invention, two or more water streams (or fuel streams) having gas-containing bubbles such as oxygen are collided. As a result, the bubbles are broken and made fine (subdivided), and the dissolution of the gas in the bubbles into the water flow (or fuel flow) is promoted.
Hereinafter, the present invention will be described by dividing it into a first invention relating to gas dissolution in a water stream and a second invention relating to oxygen-containing gas dissolution in a fuel stream.
In a conventional aeration process, the method of promoting the dissolution of air by causing the water to be treated to collide with the collision surface is expressed as “entraining air” in the conventional patent document, which promotes the destruction of bubbles and the dissolution of air and oxygen. There is no description that. Even if the bubbles in the water to be treated are made fine by the collision of the treatment target water with the collision surface, the bubbles are scattered from the treatment target water to the surroundings because the collision surface is in contact with the atmosphere. There is a possibility that it is difficult to say that it is an effective dissolution method.

On the other hand, in the first invention, two or more water streams having oxygen-containing bubbles are caused to collide, and the bubbles in the water stream are refined by the impact and remain in the water stream as they are. This increases the surface area of the bubbles and promotes the dissolution of oxygen in the bubbles into the water flow.
The water flow of the first invention is usually obtained as water containing oxygen-containing bubbles, usually air bubbles, by feeding raw water (for example, tap water) with a pump. However, depending on the application, the air concentration is obtained by blowing air in advance. The impurity concentration may be further decreased by purifying tap water or purifying tap water.

In the first invention, a plurality of water streams having such oxygen-containing bubbles are caused to collide. It is desirable that the number of water streams be two and that they collide with each other at 180 °, that is, frontal collision. As a result, both water streams collide at a speed equal to the sum of the flow velocities of both water streams, and the impact reaches several to ten times that when a single water stream collides with a stationary surface, giving each water stream the maximum impact. The bubbles in the water stream are broken and refined, and the dissolution of oxygen in the bubbles into the water stream is promoted.
The number of water streams and the collision angle are not limited to this, and three water streams can collide with each other at 120 °, or four water streams can collide with each other at 90 °. It is also possible to collide at an angle other than 180 °. In either case, each water stream is given a significantly greater impact than when a water stream having bubbles impinges on a stationary surface, facilitating the destruction of bubbles and the dissolution of oxygen into the water stream.

Although the solubility of oxygen in water at room temperature and normal pressure is about several ppm, according to the first invention method, the solubility of oxygen is further increased.
It is desirable that two or more water streams in the first invention collide at the highest possible speed. For this purpose, it is desirable to pass a small-diameter hole or slit immediately before the collision.
However, rather than simply increasing the speed to the maximum, in the case of two water streams, the characteristics of both water streams may be slightly different, for example, one flow rate may be slower than the other, The bubble diameter can be varied. It can be inferred that when a large-diameter bubble and a small-diameter bubble collide, the small-diameter bubble collides with the large-diameter bubble to increase the breaking speed of the large-diameter bubble.

The water flow is arranged in a straight line with one end of two linear cylinders facing each other, the water flow is sent from the other end side of the two pipes by a pump, and collided on the opposite end side. However, it is difficult to obtain a high-speed water flow with this method. Therefore, it is desirable that the apparatus for producing high-concentration oxygen-dissolved water of the first invention has the following form.
That is, two supply pipes in which the distal end side of a relatively large diameter cylindrical body is formed in a hemispherical shape and a small hole is formed in the center thereof are arranged in a straight line with the two small holes facing each other, and the two It is desirable to supply a water flow having oxygen-containing bubbles from the tangential direction to the respective proximal ends of the supply pipes. These water flows swirl while contacting the inner wall of the supply pipe, move while accelerating toward the tip side, and are ejected from the small holes at high speed, and the two water streams ejected from the opposing small holes are between the small holes. Colliding in each other's space and giving each other a violent impact.

The cylindrical body may be formed so that the inner wall of the cylindrical body has the same diameter except for the tip, but if it is inclined inward from the base end side toward the tip end, acceleration is promoted, and the water flows at a higher speed. A collision is realized.
As described above, this shock destroys the bubbles in the water flow and further refines them into a large number of bubbles having a smaller diameter. As a result, the surface area of the bubbles is increased and oxygen dissolution into the water stream is promoted to obtain high-concentration oxygen-dissolved water.

The thus obtained high-concentration oxygen-dissolved water is taken out of the apparatus from the water outlet, but a baffle plate having one or more through holes may be installed at the water outlet. This baffle plate provides resistance to water flow extraction, and the water flow can be retained in the space between the small holes for a long time to promote the dissolution of oxygen.
On the contrary, the high-concentration oxygen-dissolved water may be taken out by sucking with a pump or the like from the water flow outlet provided with the baffle plate.
When the apparatus having such a configuration is used, dissolved water in which oxygen having a concentration as described above is dissolved is obtained. The high concentration oxygen-dissolved water in the first invention means dissolved water in which oxygen in this range is dissolved. .

The energy required for the operation of the first invention apparatus is basically only the energy that generates a water flow and supplies it to the apparatus main body, which is very economical.
The apparatus for producing high-concentration oxygen-dissolved water according to the first invention having such a preferred configuration is roughly divided into three types of usage. 1st is the form which immerses the whole apparatus in to-be-processed water, 2nd uses apparatus in air | atmosphere, takes out the high concentration oxygen dissolved water to produce | generate out of an apparatus, and the taken out dissolved water is required. It is a form used for a use, and the 3rd is taken out from the apparatus after making water to be treated into high concentration oxygen dissolved water using this apparatus, and after using this dissolved water for a required use, the apparatus It is a form that is recycled and reused. However, the application of the first invention is not limited to these.

As the first form of wastewater treatment by the activated sludge method, improvement of the water quality of stagnant water such as lakes and rivers, oxygen enrichment of fish farm water, facilities using seawater (for example, thermal power plants and nuclear power plants) Prevention of growth and adhesion of shellfish and algae in pipes, enrichment of oxygen in fish tanks of ginger and ocean fisheries or fish tanks of seafood transport trucks, purification of pool water, purification of stored water at water treatment plants, ballast For example, water purification.
In this form, for example, wastewater treatment by the activated sludge method, it is desirable that the high-concentration oxygen-dissolved water production apparatus main body is submerged in an aeration tank in a treatment line, and a pump for supplying water flow is installed outside the tank. . Waste water (waste water) supplied to the aeration tank contains bacteria, fungi, waste chemicals, etc., but high-concentration oxygen-dissolved water produced by the main body of the device is ejected from the water outlet into the aeration tank. And sufficient oxygen of the form which is easy to contact with the said various germs etc. is supplied to the said waste_water | drain which is to-be-processed water, and a various germs etc. are oxidized and killed. In this embodiment, wastewater containing various germs is supplied into the apparatus as a water stream, and the two water streams collide violently. However, the impact also has a great impact on the germs in the water stream. It can be inferred that some bacteria are damaged or in some cases killed.

Furthermore, for example, currently pooled water is disinfected and sterilized with hypochlorous acid, ozone, etc., but these are powerful drugs and have the disadvantage of causing inflammation when they come into contact with the human body. Cost is required.
If the apparatus for producing high-concentration oxygen-dissolved water of the first invention is submerged in the pool, the pool water can be sterilized with high-concentration oxygen-dissolved water with a small amount of energy, and the oxygen used is harmless. The safety for the user is perfect.

In addition, if water accumulates in lakes and rivers, various germs propagate and pollute the water quality. In addition, factory wastewater may flow in and cause pollution of lakes and marshes. In such a case, when the first invention apparatus is used, the amount of dissolved oxygen in lake water and river water can be increased, and the stagnant water can be further stirred to eliminate the deficiency due to the stay.
Since energy supply in lakes and rivers is more difficult than usual, the water flow may be generated using solar energy and / or wind energy.
If the apparatus of the first invention is submerged in a fish tank of a ginger or a pelagic fishing boat or a fish tank of a seafood transport truck, oxygen sufficient for the ginger and seafood in the tank obtained by the high-concentration oxygen-dissolved water obtained. Can supply fresh seafood to the consumption area even in the case of long distance. In the case of seawater fish, it is preferable to produce high-concentration oxygen-dissolved water from seawater.
Purification of sewage and human urine is also a major issue. However, in conventional aeration, contaminants in sewage and the like cannot contact with sufficient oxygen in the air, and satisfactory sterilization efficiency cannot be obtained. On the other hand, when sewage and human waste are mixed with high-concentration oxygen-dissolved water obtained by the first invention, dissolved oxygen and nanobubbles (microbubbles) come into contact with the contaminants with high contact efficiency to sterilize and decompose the contaminants. It disappears with etc.

Crude oil tankers go to oil producing countries after loading crude oil in the tanks of the hull in the oil producing countries such as the Middle East and transporting them to the country. At this time, seawater is injected into the emptied tank in order to maintain the balance of the hull. Although this seawater is called ballast water, microorganisms in the seawater are contained in the ballast water, and the tank inner wall is corroded. This corrosion of the inner wall of the tank is a major problem for crude oil tankers, and no solution has yet been proposed.
As an example of the first embodiment, when the first invention apparatus is submerged in a tank into which ballast water has been injected, the resulting high-concentration oxygen-dissolved water jets into the ballast water, killing microorganisms in the ballast water, The tank inner wall of the crude oil tanker can be protected during the voyage.

As said 2nd form, hydroponics water, agricultural water, water for fisheries industry, water for cup-type vending machines, drug dilution water, dilution water for dyes, inks and paints, dilution water for various beverages, pharmaceutical water, magnetic There are recording hard disk washing water and washing water production, ice production, jet bath water production, and semiconductor washing water pretreatment.
For example, when pretreatment of hydroponics water is performed, the germs contained in hydroponics water are killed and oxygen is dissolved in the water. Appropriate oxygen can be given.
Similarly, high-concentration oxygen-dissolved water can be used as agricultural water for growing vegetables such as tomatoes and cucumbers, or fruits such as tangerines and apples. Further, the high-concentration oxygen-dissolved water may be used by sprinkling water on a domestic vegetable garden or flower bed, or may be used for washing rice husks and the like.
The high-concentration oxygen-dissolved water of the first invention can be used not only as the first form described above but also as water for the fishery industry according to the second form. For example, when octopus and oysters are washed with high-concentration oxygen-dissolved water, “slimy” is removed by the high-concentration oxygen and it becomes easy to handle. Furthermore, when transporting seafood by truck, it is often packed in a foamed plastic box filled with ice, but if this ice is made from highly concentrated oxygen-dissolved water, ice with strong sterilization power can be obtained and transported over long distances. Be preferred. The ice obtained in this way is not limited to seafood transportation, and other cooling can be used for food.
Also, when the cup-type vending machine is used less frequently, the raw material water stays in the vending machine for a long time, and unlike the canned beverage, it is not sealed, so contamination is likely to occur. When the high-concentration oxygen-dissolved water produced by the first invention apparatus is used as raw material water as it is, a beverage free from contamination can be provided. The water quality improvement by sterilization and oxygen enrichment can also be achieved with respect to other uses of the first aspect of the present invention.
In the case of each application of the first embodiment described as the immersion type, the apparatus is used in the atmosphere without being immersed, and the generated high-concentration oxygen-dissolved water is taken out of the apparatus. You may make it use in.

As a third form, there is circulation purification such as bath water (hot spring water, bath water), heat exchanger cooling water, boiler water, and papermaking washing water. In the case of these waters to be treated, the immersion type of the first form is possible, but it is desirable to adopt the third form from the presence of bathing customers, restrictions on installation space and surrounding conditions, and the like.
In the case of bath water, the bath water extracted from the bathtub is led to a treatment tank separated from the bathtub, purified by the first invention apparatus in this treatment tank, and the purified bath water is circulated to the bathtub to drain the water in the bathtub. It can be kept clean.

In the first invention, in addition to the gas dissolution into the water flow by the gas dissolving device, a tankless line is installed either before or after the device to dissolve the gas, to treat the water flow with the gas, to pre-treat the water flow before the gas dissolution. It is desirable to maintain the inside of the tankless line at high temperature and high pressure. The high temperature in the first invention generally means 50 ° C. or higher, and the high pressure means 1 MPa or higher.
Especially in the critical state (in the case of water, 375 ° C. or higher, 22 MPa or higher), it becomes a supercritical fluid that is neither a liquid nor a gas, and its superior properties are used for extraction, purification, washing, preparation, processing, functionalization, and reaction. Promotion etc. can be executed. For example, in the case of wastewater, even if the target wastewater is simply brought into contact with the nanobubbles through the first invention apparatus, the wastewater is purified by the sterilizing power of the nanobubbles. When it is introduced into the wrestline, the contact between the waste water and the nanobubbles further proceeds and the treatment efficiency increases.
The length of the tankless line is preferably in the range of 1 m to 300 m, and the inner diameter is preferably 5 mm to 100 mm, but is not limited thereto. If the length exceeds, for example, 10 m, it is desirable to reduce the installation space by folding the tankless line. As described above, the tankless line may be installed either before or after the gas dissolving apparatus. However, it is desirable to install the tankless line downstream and to continuously process the gas-dissolved water stream at high temperature and high pressure.

On the other hand, the present invention is also a fuel combustion method according to the second invention, in which the oxygen-containing gas is dissolved as fine bubbles in the fuel stream by colliding two or more fuel streams having oxygen and then burned. And
In this method, the apparatus and conditions described in relation to the first invention can be basically applied as they are, but a fuel stream is used instead of a water stream, and an oxygen-containing gas is dissolved therein. If the oxygen-containing gas is difficult to dissolve, a surfactant may be added to the fuel. Furthermore, if ozone gas is dissolved instead of oxygen-containing gas or together with oxygen-containing gas, combustion is further promoted.
The fuel of the second invention includes all fuels, that is, household and industrial fuels, and further vehicle and aviation fuels.

Also in the second invention, as in the first invention, nanobubbles are dissolved in the fuel. Since the nanobubbles come into contact with the fuel in a very large area, if they are burned as they are, bonding with oxygen, that is, combustion proceeds with high efficiency. Therefore, the fuel can be burned smoothly and the maximum energy can be taken out for both home use and industrial use.
Vehicular and aviation fuels are once vaporized and then burned. After the nanobubbles of oxygen-containing gas are dissolved via gasoline, heavy oil, etc., this fuel is supplied to the internal combustion engine with air as usual and vaporized. Combustion after combustion causes combustion with a high oxygen content, which can be expected to significantly improve fuel consumption.

The first invention is to produce high-concentration gas-dissolved water, particularly high-concentration oxygen-dissolved water, by a simple operation of dissolving the gas in the bubbles into the water flow by colliding two or more water flows having bubbles. It is possible.
When a plurality of water streams having such oxygen-containing bubbles collide, depending on the collision angle, each water stream collides at a speed equal to the sum of the flow velocities of each water stream at the maximum. The impact at that time is not simply twice that of a single water stream colliding with the impact surface, but increases exponentially as the impact speed increases, giving each water stream the maximum impact. It is done. As a result, bubbles in the water stream are destroyed, dissolution of oxygen in the bubbles into the water stream is promoted, and the bubbles in the water stream also become ultrafine bubbles such as nanobubbles and microbubbles).
The second invention is a method in which two or more fuel streams having an oxygen-containing gas are collided to dissolve the oxygen-containing gas as fine bubbles in the fuel stream and then burn it. By dissolving the nanobubbles in the fuel stream, the contact area between the fuel and oxygen is increased, enabling efficient combustion.

Next, although an example of the high concentration oxygen dissolved water manufacturing apparatus based on this invention is demonstrated based on an accompanying drawing, this does not limit this invention.
1 is a partial longitudinal sectional view showing an example of a high-concentration oxygen-dissolved water producing apparatus according to the present invention, FIG. 2 is a partially exploded perspective view of the apparatus of FIG. 1, and FIG. 3 is a guide for three sheets of the apparatus of FIG. It is a side view (a bolt hole is omitted) of a board and three spacers.

A laterally cylindrical outer cylinder 1 has a guide pipe 2 of high-concentration oxygen-dissolved water bent upward at the center of the upper surface, and a horizontal flange 3 is joined outwardly to the upper end edge of the guide pipe 2. Yes.
On the upper surface of the horizontal flange 3, a baffle plate 5 having a slightly small diameter and four through holes 4 (only one is shown) is located. On the baffle plate 5, high-concentration oxygen-dissolved water with a horizontal flange 6 is provided. A take-out (spout) port 7 is provided, and the high-concentration oxygen-dissolved water take-out port 7 is fixed to the outer cylinder 1 by tightening the horizontal flanges 3 and 6 with bolts 8.

  A support plate 9 whose upper part is curved in a semicircular shape is joined to the outer peripheral sides of both ends of the outer cylinder 1. (Flange) 11 is fitted. The outer edge of the base end portion of the cylindrical turning inner cylinder 14 whose tip side is formed as a hemispherical ejection portion 13 is joined to the circular hole 12 at the center of the inner cylinder mounting plate 11. Is formed with a small-diameter ejection hole 15. 1 is formed such that the diameter of the left-hand ejection hole 15 in FIG. 1 is smaller than the diameter of the right-hand ejection hole 15 '. The hole diameters of both the ejection holes may be the same.

  Three guide plates and three spacers shown in FIG. 3 are laminated on the outer surfaces of the support plate 9 and the inner cylinder mounting plate 11. The first spacer 16 that contacts the support plate 9 and the inner cylinder mounting plate 11 is formed with a circular hole 17 corresponding to the inner cylinder 14, and the first guide plate 18 that contacts the first spacer 16 includes A swirl flow forming hole 20 corresponding to the circular hole 17 of the first spacer 16 and having a notch 19 formed in the vertical tangential direction is formed.

A second spacer 22 having a pair of left and right longitudinal notches 21 is in contact with the outside of the first guide plate 18 at a location corresponding to the tip of the notch 19. On the outside of the second spacer 22, a second guide plate 24 having upper end portions aligned with the pair of cutouts 21 and formed with a through hole 23 that is formed in a generally upward “U” shape. Are in contact.
A third spacer 26 formed with a circular hole 25 is in contact with the outside of the second guide plate 24 so as to overlap a part of the horizontal hole below the through hole 23. A third guide plate 28 having a supply port 27 for oxygen-containing bubbling water flow is in contact with the outside of the third spacer 26 at a location corresponding to the circular hole 25.

The three guide plates 18, 24, and 28 and the three spacers 16, 22, and 26 are integrated with each other by fastening bolts 30 to bolt holes 29 that are respectively drilled. 9 is fixed.
Reference numeral 31 denotes a shielding plate that is joined to the periphery of the turning inner cylinder 14 and whose outer edge is in close contact with the inner wall of the outer cylinder 1.

The point of production of high-concentration oxygen-dissolved water by the high-concentration oxygen-dissolved water production apparatus having such a configuration will be described.
Two water streams 32 and 32 'having oxygen-containing bubbles, usually air-containing bubbles, generated by a pump or the like are supplied from the respective supply ports 27 of the left and right third guide plates 28 in FIG. Of these water flows, the left water flow 32 passes through the circular hole 25 of the third spacer 26 and reaches the through hole 23 of the second guide plate 24, where it is divided into left and right as shown in FIG. It is supplied to the longitudinal grooves on both sides of the hole 23. These water flows pass through the notches 21 of the second spacer 22 and are supplied to the leading ends of both notches 19 of the first guide plate 18. Both water flows are supplied at high speed from the tip of the notch 19 to the swirl flow forming hole 20 from the tangential direction, reach the swirl inner cylinder 14 from the circular hole 17 of the first spacer 16, and follow the inner wall of the swirl inner cylinder 14. A swirling flow 34 having bubbles 33 is formed.

The swirling flow 34 reaches the ejection portion 13 at the tip of the inner cylinder 14, and is ejected from the ejection hole 15 toward the other ejection hole 15 'while increasing the speed while contacting the hemispherical inner wall.
Similarly, the water flow supplied from the right supply port 27 reaches the ejection hole 15 ′ as a swirling flow, and is ejected from the ejection hole 15 ′ toward the other ejection hole 15.
The left and right swirling flows 34 collide in the middle of the two ejection holes 15 and 15 ′ in the inner cylinder 14 as a linear water flow. The impact of this collision does not double the speed of the two swirling flows 34, but increases exponentially. Accordingly, the bubbles 33 contained in both the water streams are further refined by impact due to the water stream collision to become fine bubbles 35, and the surface area as the bubbles increases geometrically, increasing the chance of contact with water and increasing the chance of contact with water. Oxygen dissolves in water and its solubility is maximized.

Furthermore, for example, when oxygen is dissolved by causing a water stream to collide with the impact surface, oxygen is easily diffused into the atmosphere, and the solubility may not be sufficiently increased. On the other hand, in the illustrated example, since the bubbles are not opened to the atmosphere at the collision point of the water flow, the oxygen dissolution efficiency is maximized.
Moreover, since the water flow transferred from the inner cylinder 14 to the inner space of the outer cylinder 1 is confined in a narrow space by the baffle plate 5 and the shielding plate 31, the miniaturization of the bubbles is promoted.

As described above, the diameters of both the ejection holes 15 and 15 'are different from each other, and bubbles in the water stream ejected from the left ejection hole 15 having a small diameter are in the water stream ejected from the right ejection hole 15'. Bubble diameter is smaller than bubble. When bubbles having different bubble diameters collide with each other, it can be estimated that turbulence occurs between the colliding bubbles and the destruction of the bubbles is promoted. For the same reason, the speeds of the two water streams ejected from the ejection holes 15 and 15 'may be made different.
Further, unlike the illustrated example, the inner wall of the inner cylinder 14 other than the hemispherical jet portion 13 is inclined inward toward the jet portion 13 to increase the speed of the water flow jetted from the jet holes 15 and 15 '. Also good.
The baffle plate 5 described above does not have to be used. On the contrary to promoting the retention of the high-concentration oxygen-dissolved water generated by the baffle plate in the apparatus, the high-concentration oxygen-dissolved water outlet 7 is connected to a pump, It is also possible to promote the removal of the high-concentration oxygen-dissolved water by suctioning with a vacuum.

The pump 46 is connected to a lake water pumping pipe 47 and a water flow supply pipe 48, and the tip of the water flow supply pipe 48 is branched and connected to a pair of bubbly water flow supply ports 27 of the device 41. .

  When the pump 46 is operated, the lake water is pumped up from the lake water pumping pipe 47 to form gas-liquid mixed water containing air bubbles, and is supplied to the bubble water flow supply port 27 of the apparatus 41 through the water flow supply pipe 48. . The two water streams supplied to the two supply ports 27 collide with each other in the same manner as in FIG. 1 to generate high-concentration oxygen-dissolved water having a large number of fine bubbles 35. It is ejected from the spout 49 into the lake 42. This high-concentration oxygen-dissolved water supplies enriched oxygen to the lake water to oxidize and sterilize the lake water, and stir the entire lake water.

Thereby, purification of lake water can be carried out. The energy required for this purification work is only the energy for driving the pump. If the solar panel or wind power generator is loaded on the pit 45 and the energy generated by these is used as the pump driving energy, it is an artificial energy. Without the purification of lake water.
This apparatus does not need to be operated constantly, and may be operated intermittently. In particular, when the obtained hydropower and wind energy are insufficient for regular operation, intermittent operation is preferable.
Also, unlike the example shown in the figure, a pump is installed on the reed 45 without sinking to the bottom of the lake, and lake water is supplied to this pump to generate high-concentration oxygen-dissolved water. It may be ejected.

  FIG. 9 is a longitudinal sectional view showing still another example of the apparatus for producing high-concentration oxygen-dissolved water according to the present invention, and FIG. 10 is an exploded perspective view of the apparatus of FIG.

  A cylindrical body 91 having a horizontally-oriented cylindrical shape has a circular hole formed in the center of the upper surface thereof, and constitutes a high-concentration oxygen-dissolved water outlet 92. Although not shown in the drawing, the baffle plate having a through hole may be positioned, for example.

Two first circular packings 96 each having a circular hole 93 at the center, a plurality of bolt holes 94 at the peripheral part, and a water flow supply hole 95 at the lower part are in contact with both end edges of the cylindrical main body 91. Each of the two first circular packings 96 abuts a supply pipe installation disk 97 having a circular hole 93, a bolt hole 94, and a water flow supply hole 95 at the same position. The outer edges of the respective base end portions of a cylindrical supply pipe (turning inner cylinder) 99 formed as a hemispherical ejection portion 98 at the distal end side are joined, and a small-diameter ejection hole 100 is formed at the center of the distal end of the ejection portion 8. Has been. In addition, although the hole diameter of both the ejection holes 100 of both the ejection parts 98 was made the same, you may make a hole diameter different.
The supply pipe installation disk 97 is in contact with the first circular packing 96 so that the supply pipe 99 is positioned in the cylindrical space 101 in the cylindrical main body 91.

A second circular packing 102 having the same configuration as the first circular packing 96 is in contact with the outer surface side of the supply pipe installation disk 97.
A disc-shaped lid 103 abuts against the second circular packing 102, and the bolts 104 are passed through the bolt holes 94 and fastened, whereby the cylindrical main body 91 and the lids 103 on both sides are integrated. ing. On the inner surface side of the lid 103, in the example of FIG. 10, arcuate guide pieces 105 having three thin tips formed in a protruding manner are formed.

A water flow supply port 106 is perforated upward in the center lower surface of the cylindrical main body 91, and the water flow supply port 106 branches right and left within the inner wall of the cylindrical main body 91, and flows into the water flow supply path 107 toward the lid 103. Is forming.
The space in the lid 103 communicates with the supply pipe 99.

The point of production of high-concentration oxygen-dissolved water by the high-concentration oxygen-dissolved water production apparatus having such a configuration will be described.
A water flow 108 having oxygen-containing bubbles, usually air-containing bubbles, generated by a pump or the like is supplied from the water flow supply port 106 into the inner wall of the cylindrical main body 91. The water flow 108 reaches the water flow supply path 107 and branches right and left. The branch flows 109 flow in the water flow supply path 107 toward the left and right lids 103, respectively, and the outer surface of the guide piece 105 in the lid 103. And enters the supply pipe 99 while flowing spirally. This water flow includes bubbles 110 of oxygen-containing gas, and proceeds as a high-speed swirl flow 111 along the inner surface of the supply pipe 99.

The swirl flow 111 reaches the ejection part 98 at the tip of the supply pipe 99 and is ejected from the ejection hole 100 toward the space 101 of the cylindrical main body 91 while contacting the hemispherical inner wall and increasing the speed. Since an outward force is applied to the swirling flow 111 at the time of ejection, and the ejection hole 100 has a certain size, the swirling flow 111 is not only directed toward the other ejection hole 100 but also radially outward. To erupt.
The left and right swirl flows 111 collide in the middle of both ejection holes 100 in the space 101 of the cylindrical main body 91 as a linear or radial water flow. The impact of this collision does not double the speed of the two swirling flows 111 but increases exponentially. Therefore, the bubbles 110 contained in both water streams are further refined by impact due to the water current collision to become fine bubbles 112, and the surface area as a bubble increases geometrically, increasing the chance of contact with water and increasing in the air. Oxygen dissolves in water and its solubility is maximized.

  Furthermore, for example, when oxygen is dissolved by causing a water stream to collide with the impact surface, oxygen is easily diffused into the atmosphere, and the solubility may not be sufficiently increased. On the other hand, in the illustrated example, since the bubbles are not opened to the atmosphere at the collision point of the water flow, the oxygen dissolution efficiency is maximized.

If the hole diameters of the two ejection holes 100 are different, bubbles in the water stream ejected from the ejection hole 100 having a smaller hole diameter are smaller than those in the water stream ejected from the other ejection hole 100. When bubbles having different bubble diameters collide with each other, it can be estimated that turbulence occurs between the colliding bubbles and the destruction of the bubbles is promoted. For the same reason, the speeds of the two water streams ejected from the ejection hole 100 may be different.
Further, unlike the illustrated example, the inner wall of the supply pipe 99 other than the hemispherical jet part 98 may be inclined inward toward the jet part 98 to increase the speed of the water flow jetted from the jet hole 100.

11a to 11c are schematic views showing other examples of the lid body of the high-concentration oxygen-dissolved water producing apparatus exemplified in FIGS.
11a shows an example in which the number of guide pieces 105a of the lid 103a is two, FIG. 11b shows an example in which the number of guide pieces 105b of the lid 103b is four, and FIG. 11c shows that the number of guide pieces 105c of the lid 103c is five. As an example.
Regardless of which lid 103a-c is used, the water flow supplied to the lid progresses spirally along the outer surface of the guide piece to generate a swirl flow. The swirl flow is most efficiently generated by the lid 103c.

FIG. 12 is a partial longitudinal sectional view showing still another example of the high-concentration oxygen-dissolved water producing device according to the present invention. The same members as those in FIGS.
In the illustrated example, a horizontal hole 113 passes through the center of both lids 103d, oxygen-containing gas injection pipes 114 and 115 are inserted into the horizontal hole 113, and the distal end of the left oxygen-containing gas injection pipe 114 is a supply pipe. 99, the distal end of the oxygen-containing gas injection pipe 115 on the right side is located at the base end of the supply pipe 99.
When the same operation as in the example of FIG. 9 is performed while injecting air from both the oxygen-containing gas injection pipes 114 and 115 into the supply pipe 99 with the apparatus of this example, the amount of air in each supply pipe 99 (the number of bubbles) Therefore, the amount of air ejected from the ejection hole 100 into the space 101 in the cylindrical main body 91 is increased, and the amount of air dissolved in the water flow in the space 101 is also increased, thereby further increasing the concentration. The oxygen-dissolved water is taken out from the high-concentration oxygen-dissolved water outlet 92.

FIG. 13 is a partial vertical cross-sectional view showing still another example of the high-concentration oxygen-dissolved water producing apparatus according to the present invention. The same members as those in FIG.
In the illustrated example, the water flow supply port 116 is not provided in the lower part of the cylindrical main body, but the water flow supply port 116 is provided in the lower part of the lids 103e. Also in this example, the water flow supplied into the lid 103e comes into contact with the outer surface of the guide piece and advances spirally to form a swirling flow.

FIG. 14 is a partial longitudinal sectional view showing an example in which a tankless line is connected to the high-concentration oxygen-dissolved water producing apparatus according to the present invention.
A tankless line 124 is connected to the other end of the auxiliary pipe 123 connected to the high concentration oxygen dissolved water outlet 122 of the high concentration oxygen dissolved water production apparatus 121. The tankless line 124 is accommodated in the oil bath 125 and is folded three times in the illustrated example. A heating wire 126 is accommodated in the oil bath 125 to heat the oil in the oil bath 125.
When waste water containing a large amount of contaminants and microorganisms is supplied to the high-concentration oxygen-dissolved water production apparatus 121 and is ejected from the nozzle and collided as described above, air nanobubbles are dissolved in the waste water. When dissolved in the air, the oxygen in the nanobubbles comes into contact with the wastewater to decompose or sterilize some of the pollutants and microorganisms. Next, the waste water is led from the high concentration oxygen-dissolved water outlet 122 to the tankless line 124.
Since the inside of the tankless line 124 is maintained at a high temperature and high pressure, the nanobubbles in the waste water react with the pollutants and microorganisms efficiently, and the pollutants and microorganisms are almost completely removed and discharged without further processing. it can.
Since the tankless line 124 is folded back, the tankless line 124 is compact and can perform wastewater treatment with a small installation area.
