Description

A device for generating ultra-fine bubbles using the central flow and surface flow generated by the spirals in which the wrinkles are formed continuously, and a method for generating ultra-fine bubbles using the same {Apparatus for generating nano & micro bubbles by using central and surface flow generated by the spirally continuous wrinkles and Method using the same}

The present invention relates to a device for generating an ultra-fine fabric having a nano unit of diameter and a method for generating an ultra-fine fabric, and more particularly, a plate material is formed in a helical shape to form an inner central flow in a linear direction. It constitutes the inner center pipe path that generates, and a plurality of wrinkles that generate helical wrinkle surface flows are fixedly formed on the surface of the plate, and continuously wrinkles generate a large amount of ultra-fine bubbles per unit volume of the incoming liquid and gas. The present invention relates to an apparatus for generating ultra-fine bubbles using the central flow and surface flow generated by the formed spiral, and a method for generating ultra-fine bubbles using the same.

In recent years, interest in the field of utilizing liquids (such as water) containing gases such as air, oxygen, and ozone gas as microbubbles is increasing. For example, water containing ozone gas microbubbles can be used for cleaning, washing, and purification of wastewater, and water containing oxygen microbubbles can be used for purification of wastewater or lakes.

Specifically, in a water treatment plant that treats wastewater, a technology for purifying wastewater by supplying oxygen to the wastewater by bubbles is used. However, the conventional microbubble generator is equipped with a nozzle that injects a plurality of gases below the treatment tank containing wastewater, and the gas pressurized from the outside of the treatment tank is sprayed to the nozzle through the transfer pipe, thereby generating bubbles and rising. It is common to have a structure that is However, the diameter of the air bubbles generated by the conventional technique is 40-50 μm or more, and when the diameter of the air bubbles is large, there may be a problem that the efficiency of cleaning and purification is deteriorated.

In other words, since the bubbles generated by the conventional technology have a large diameter, the efficiency decreases when used for cleaning, washing, and purification of wastewater, and over time, the bubbles rise to the surface and disappear, reducing the amount of microbubbles per unit volume of liquid. When used for cleaning, washing, or purification of wastewater, there may be a problem that the efficiency is further reduced over time. In other words, when the diameter of the air bubbles increases or increases as the diameter increases, the distribution of micro-bubbles in the liquid is uneven and the distribution is narrowly concentrated.Therefore, a very low problem in efficiency occurs when cleaning, washing, and purifying wastewater. I can.

In general, microbubbles (microbubbles (1 micro = 1/1000mm)) appear white like milk, so they can be distinguished and confirmed externally, but ultra-fine bubbles (nanobubbles (1 nano = 1/1000000mm)) are eyes There is a difference that cannot be checked with a laser beam and can only be checked when irradiated with laser light. General bubbles including microbubbles (microbubbles) have a greater buoyancy compared to water pressure and rise to the surface within a few seconds-minutes and rupture at the surface, but ultra-fine bubbles (nanobubbles) dissolve the gas in water. ), so there is a difference in that the dissolved state is maintained for a very long time in the absence of external vibration.

Such ultra-fine bubbles (nano bubbles) have physical and chemical properties such as gas dissolution effect, self-pressurization effect, and charging effect, and are used in various areas due to these physical and chemical properties. In recent years, especially in the fields of fishing and agriculture, it is used for various aquaculture and hydroponic cultivation, and in the medical field, it is used for precise diagnosis such as cancer diagnosis, or various regenerative treatments using skin regeneration effects, various sterilization treatments using sterilization effects, and physical therapy. In the environmental field, it is used for high-purity water treatment and wastewater treatment. In addition, by dissolving and utilizing a large amount of ultrafine foam per unit dose in the hot spring water, it can generate excellent effects on skin beauty.

Existing microbubbles are generally generated using various methods such as rotating liquid retention type, static mixer type, ejector type, venturi type, pressure melting type, ultrasonic type, electrolysis type, and microporous filter type. do. However, the conventional micro-bubble generation methods are not suitable for the generation of ultra-fine bubbles, and the micro-bubbles generated by the conventional micro-bubble generation method have a larger buoyancy compared to the water pressure, so that they rise to the water surface within a few seconds-minutes and rupture at the surface. Therefore, there is a problem that the amount of microbubbles per unit dose decreases with the passage of time, and the efficiency is further reduced with the passage of time when used in various fields such as medical, environmental, fishing, and agricultural fields.

It can be separated by a strength gun.

In the apparatus for generating ultra-fine bubbles by using the central flow and the surface flow generated by the continuous corrugated spiral, the inventors of the present invention, at one end of the tubular body 1000 is a space in which a liquid with pressure flows in. An inflow space part 100 is formed, and at the other end of the body 1000, a pulverizing mixing space part 200 for pulverizing gas and mixing it with a liquid is formed, and the inflow space part 100 and crushing mixing space part 200 Is separated by a guide tube (300). The guide tube 300 is preferably in the form of a funnel having a large diameter toward the inlet space portion 100 and a smaller diameter toward the pulverizing and mixing space portion 200. As the guide tube 300 has a funnel shape, when a liquid containing bubbles flows into the grinding and mixing space 200 through the guide tube 300, a pressurizing action occurs.

A liquid inlet 110 through which external water formed at one end of the body 1000 flows into the inlet space 100 and a gas through which external air formed at an upper end of the body 1000 flows into An inlet 120 is provided, and a liquid is introduced through the liquid inlet 110 and gas is introduced through the gas inlet 120 to form a liquid containing bubbles in the inlet space 100. The liquid containing the bubbles is pressurized while flowing into the pulverizing and mixing space part 200 through the guide tube 300. The pulverization and mixing space part 200 includes a gas mixture liquid outlet 210 through which a liquid containing an ultrafine foam formed at the other end of the body 1000 flows to the outside, and a bubble formed inside the other end of the body 1000 A pulverizing mixer 220 for pulverizing and separating the pulverization and mixing unit 220 is provided, and the liquid containing air bubbles introduced into the pulverizing and mixing space 200 while being pressurized by the guide tube 300 has ultra-fine bubbles in the pulverizing mixer 220 The gas mixture liquid is pulverized and separated into a strength cloth to form a gas mixture liquid, and the gas mixture liquid containing the ultrafine fabric is discharged to the outside through the gas mixture liquid outlet 210.

The crushing mixer 220 has a structure in which the plate material 221 is continuously formed in a spiral shape. As the plate material 221 is continuously formed in a spiral shape, an inner center pipe 223 is formed at the center, and the liquid containing bubbles located at the center of the pulverizing and mixing space part 200 is in the center of the spiral plate material 221 It flows through the formed inner central pipe 223 and generates an inner central flow 222 in a linear direction. A plurality of corrugations 225 are fixedly formed on the surface of the plate material 221 so that the liquid containing air bubbles located in the upper and lower portions of the pulverizing and mixing space 200 generates a helical corrugated surface flow 224. That is, in the apparatus for generating ultra-fine bubbles by using the central flow and the surface flow generated by the spiral in which the present invention is continuously corrugated, it is pressed in the guide pipe 300 and flows into the pulverizing and mixing space 200. The liquid containing bubbles has two flows: a linear inner central flow 222 as mainstream and a helical wrinkle surface flow 224 as reflux.

The wrinkles 225 may be formed by alternating wrinkle wings 226 that narrow and increase inward and wrinkle bones 227 that widen and deepen inward. The corrugated blade 226 has a shape protruding in the direction of the liquid inlet 110, and the corrugated bone 227 has a shape settled in the direction of the gas mixture liquid outlet 210. The liquid containing air bubbles flows along the plurality of wrinkles 225 formed on the surface of the spiral plate 221 to generate a helical wrinkle surface flow 224. When the helical wrinkle surface flow 224 is generated, air bubbles flow along the plurality of wrinkles 225 formed on the surface of the spiral plate 221 and protrude from the wrinkle wing 226, which is compressed and contracted, and the wrinkles settled. After repeating the process of decompression and expansion in the valleys 227, when the water pressure is greater than the surface tension of the bubbles, they are crushed into ultra-fine bubbles.

At the boundary between the corrugated wing 226 and the inner center pipe 223, an inner end 228 of the corrugated wing may be formed, and at the boundary between the corrugated bone 227 and the inner center pipe 223, the inner end of the corrugated bone 229 Can be formed. Bubbles present in the linear inner central flow 222 rise from the center to the top due to buoyancy, and move toward the inner end of the corrugation blade 228 and the inner end of the corrugation bone 229, and the inner central flow in the linear direction 222 It is located at the boundary of the helical wrinkle surface flow (224).

The wrinkles 225 may be formed by alternating wrinkle wings 226 that narrow and increase inward and wrinkle bones 227 that widen and deepen inward. In this case, the wrinkles 225 may be fixedly formed on the surface of the plate material 221 at equal intervals.

As the wrinkle wing 226 is formed narrow and high inward, when the liquid containing air bubbles flows along the plurality of wrinkles formed on the surface of the spiral plate, the air bubbles are easily increased in the wrinkle wing 226 that narrows and increases inward. Bubbles can be easily decompressed and expanded in the corrugated bone 227 that can be contracted and widens and deepens inward. In this way, the bubbles are easily increased in the wrinkle wings 226 that narrow and rise inward, and the bubbles are easily decompressed in the wrinkle bone 227 that widens and deepens inward, so that the wrinkle wings 226 that narrow and rise inward and increase inwardly Bubbles in the wider and deeper corrugations 227 can be easily crushed into ultra-fine fabrics. In the inner end 228 of the corrugated blade existing at the boundary between the corrugated blade 226 and the inner central pipe 223, and the inner end 229 of the corrugated bone existing at the boundary between the corrugated blade 227 and the inner central pipe 223 When the bubbles existing in the linear inner central flow 222 are guided toward the corrugation 225 by buoyancy and impact pressure with the surface of the linear inner central flow 222, the bubbles are formed at the inner end of the corrugated wing 228 and corrugated bone. At the inner end 229, it is torn by the collision pressure with the surface of the inner central flow 222 in the linear direction, so that it can be separated into an ultra-fine cloth.

Furthermore, bubbles are guided to the corrugations 225 by the collision pressure with the surface of the inner central flow 222 in the linear direction at the inner end 228 of the corrugated blade and the inner end 229 of the corrugated bone, and the bubbles are led to the inner central flow in the linear direction ( 222) The impact pressure by the surface is applied, and the bubbles can be easily separated into ultra-fine bubbles by the impact pressure by the surface of the inner central flow 222 in the linear direction. The arrows indicated in red in FIG. 3 indicate the impact pressure caused by the surface of the inner central flow 222 in the linear direction applied to the bubble.

It is a drawing showing the appearance that it is enlarged and crushed into an ultra-fine gun.

According to FIG. 4, when a liquid flows through the liquid inlet 110 from the inlet space 100 and the gas flows through the gas inlet 120 to form a liquid containing bubbles, the liquid containing bubbles is introduced into the guide tube. A liquid containing bubbles introduced into the pulverizing and mixing space 200 through 300 and located on the upper and lower sides of the pulverizing and mixing space 200 forms a plurality of wrinkles 225 on the surface of the spiral plate 221 It flows along and generates a helical corrugated surface flow 224, and bubbles in the helical corrugated surface flow 224 flow along a plurality of corrugations 225 formed on the surface of the helical plate material 221, while the liquid inlet 110 In the corrugated wing 226 having a shape protruding in the direction, the pressure is increased and contracted, and in the corrugated bone 227, which is a type that has settled in the direction of the gas mixture liquid outlet 210, the process of decompression and expansion is repeated. In this way, when the pressure increase, contraction, decompression, and expansion process are repeated and the water pressure becomes larger than the surface tension of the bubbles, the bubbles are crushed into smaller bubbles. When the spiral direction wrinkle surface flow 224 continuously flows along the plurality of wrinkles 225 formed on the surface of the spiral plate 221, the process of pulverizing the air bubbles into smaller air bubbles is repeated, and the air bubbles are ultrafine.

The liquid flows into the body inlet space 100 through the liquid inlet 110 and the gas flows into the body inlet space 100 through the gas inlet 120 to form a liquid containing bubbles. , The liquid containing air bubbles flows into the pulverizing and mixing space 200 while being pressurized by the guide tube 300. The liquid containing the pressurized air bubbles located on the upper and lower sides of the pulverizing and mixing space 200 flows along a plurality of wrinkles 225 formed on the surface of the spiral plate 221 to generate a helical wrinkle surface flow 224 . The liquid containing pressurized air bubbles located in the center of the pulverizing and mixing space part 200 flows through the inner central pipe 223 formed at the center of the spiral plate 221 to generate an inner central flow 222 in a linear direction.

The wrinkles 225 may be formed by alternately consisting of wrinkle wings 226 that narrow and increase inward and wrinkle bones 227 that widen and deepen inward, and the wrinkles 225 are formed on the surface of the plate material 221 It can be fixed at equal intervals. The inner side of the crease wing 226 may be formed with the inner end 228 of the crease, and the inner end 229 of the inner side of the crease bone 227 may be formed. Due to the structure of the corrugation 225, the air bubbles in the spiral direction corrugated surface flow 224 flow along the plurality of corrugations 225 formed on the surface of the spiral plate 221 and protrude in the direction of the liquid inlet 110. Branches are compressed and contracted in the corrugated wing 226, and the process of decompressing and expanding in the corrugated bone 227, which is a type that has settled in the direction of the gas mixture liquid outlet 210, is repeated. If the water pressure becomes larger than the surface tension of the bubbles during the repeated contraction and expansion process, the bubbles are crushed into smaller bubbles. As described above, the air bubbles in the spiral direction wrinkle surface flow 224 continue to flow along the plurality of wrinkles 225 formed on the surface of the spiral plate 221, repeating the process of being pulverized into small air bubbles, and being crushed into ultra-fine bubbles. do. In addition, the air bubbles present in the linear inner central flow 222 rise from the center to the top due to buoyancy, and move toward the inner end of the corrugation blade 228 and the inner end of the corrugation bone 229 in the linear direction. The air bubbles are induced to the corrugation 225 by the impact pressure with the surface, and by the impact pressure caused by the surface of the linear inner central flow 222 generated at the inner end 228 of the corrugated blade and the inner end 229 of the corrugated bone It can be easily separated by an ultra-fine gun.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and is generally used in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims.
