Description

{A air supply control system for nanobubbles}

The present invention is a nanobubble generator designed to control the supply of air to a nanobubble generator that generates nanobubbles containing fine bubbles with a microscopic diameter through the dissolution pressure of mixed water mixed with raw water and air. It is about the air supply control system.

Specifically, it relates to an air supply control system for nanobubbles that improves nanobubble generation efficiency by stably maintaining an appropriate amount of air for efficient generation of nanobubbles in relation to the dissolution pressure of the dissolution space.

In general, nanobubbles are ultra-fine bubbles that cannot be seen with the eye. They are 1/2,000 the size of regular bubbles and are fine air particles in skin pores less than 25㎛. When they disappear, 1) 40KHz ultrasound is generated, 2) It generates a high sound pressure of 140db, and 3) generates instantaneous high heat of 4,000 to 6,000 degrees.

In other words, normal bubbles rise in water and burst at the surface, but nanobubbles shrink under pressure under water and disappear while generating various types of energy.

These nanobubbles are ultra-fine bubbles that mainly occur when water and air are violently rotated.

Such nanobubbles are used in various fields due to their physical and chemical properties such as "gas dissolution effect, self-pressurization effect, and electrification effect", and in recent years, they have been used in various aquaculture and hydroponic cultivation, especially in the fishing and agricultural fields. In the medical field, it is used for precise diagnosis, and is currently being used in various fields such as physical therapy, high-purity water treatment, and environmental devices.

In other words, its field of use is wide ranging from hot spring bathing to cancer diagnosis, and it is known to regenerate the skin and also has an excellent sterilizing effect.

Nanobubbles as described above are generated in various ways, such as swirling liquid flow type, state mixer type, ajector type, venturi type, pressure dissolution type, ultrasonic type, electrolysis type, and micropore filter type.

In order to generate nanobubbles through these various nanobubble generating facilities or devices, a liquid (feed water) mixed with gas is supplied and the gas is converted into microbubbles to generate nanobubbles.

In the above, the process of converting feed water into microbubbles is accomplished through a process in which feed water containing bubbles (a mixture of water and air) is separated and compressed while passing through a micropipe passage of a generating means equipped with a micropipe passage.

As one of the nanobubble generators that generate nanobubbles as described above, there is Korean Patent Registration No. 10-1146040 (name: nanobubble generator), and the nanobubble generator, as described in the publication, A bubble generating chamber is provided with a water inlet through which water flows in, an air inlet through which air flows in, and an outlet through which air is discharged, and is provided between the water inlet, air inlet, and discharge port of the bubble generating chamber, and is rotated by being fitted on the shaft of a motor. and a rotating disk equipped with a plurality of guide holes through which water introduced through the air inlet is guided, and which is provided to be in close contact with the moving direction of the water and air of the rotating disk and diverts the water and air guided through the guide holes in an outward direction. It consists of a fixed disk provided with a plurality of stirring pieces protruding in the direction of the rotating disk to stir water and air as the rotating disk rotates.

Accordingly, the water and air are not only stirred by friction with the stirring pieces, but also are rubbed while passing between the stirring pieces in a jig jack, so that the water and air are strongly stirred and compressed as if crushed.

This impact-type microbubble generator not only requires a high pressure of 5 to 20 bar, but also has a large flow loss and requires multiple nozzles and a large mixing tank, which has the disadvantage of complicating the structure and equipment of the device. .

On the other hand, the swirling liquid retention type microbubble generator generates nanobubbles through the inflowing transfer pressure in the process of transferring mixed water of water and air through the space in a spiral shape, like the impact nozzle type. It is designed to generate nanobubbles due to the eddy pressure generated while the mixed water is being transported while forming a vortex by forming a spiral-shaped pipe.

However, this swirling liquid retention type micro-bubble generating device has the problem of not being able to generate micro-bubbles through a single nozzle and not only requiring high pressure but also requiring a large mixing tank.

Recently, a nanobubble generating system is used to generate nanobubbles by dissolving the air contained in the mixed water of water and air supplied from the outside through a dissolving means provided with a dissolving space internally designed to create dissolution pressure of the air. This is currently being proposed.

In other words, as the air pressure in the dissolution space continues to increase due to the supply of mixed water, a dissolution pressure that causes dissolution of the air remaining in the dissolution space is generated.

Therefore, in the dissolution space, nanobubble water is smoothly formed by the generation of mixed water due to mixing of raw water (tap water) and air and the dissolution of air contained in the mixed water.

In Korean Patent Registration No. 10-2105794 (name: Nanobubble generator), as described in the gazette, it has a supply port through which mixed water having a transfer pressure is supplied and a discharge port for discharging to the outside, and between the supply port and the discharge port. In a nanobubble generating device comprising: a dissolution means having a dissolution space sealed to the outside and configured to create a dissolution pressure of gas against water; The dissolving means is configured such that the inlet of the supply port is disposed on the outer surface, the outlet of the supply port is disposed on the upper surface, and a supply pipe through which the mixed water is supplied from the outside is connected to discharge the water to the upper surface. The inlet of the discharge port is on the upper surface. In the disposed state, the outlet of the discharge port is disposed on the outer surface and a discharge pipe through which the mixed water is discharged from the outer side is connected to the dissolving body and discharged to the outside; The lower part is open and the open lower part is assembled by being bound to the upper part of the dissolving body, and has a dissolving space inside which is configured to form a dissolving pressure for the mixed water supplied through the outlet of the supply port. ; At the outlet of the supply port on the upper surface of the dissolving body, the injection pipe has a vertical length and has a transfer pipe inside through which the mixed water is transported, and is configured to spray the mixed water to the upper surface of the dissolving tank to apply collision pressure. A nanobubble generator equipped with this binding tube is described.

However, the conventional nanobubble generating devices and systems described above had a problem in that they were unable to properly form an appropriate amount of air in the dissolution space where nanobubbles were formed through dissolution pressure, thereby failing to maximize nanobubble generation efficiency.

In other words, when the generation efficiency of nanobubbles decreases due to a decrease in the amount of air relative to the dissolution pressure in the dissolution space, there is a problem in that the quality of the generated nanobubbles decreases as this cannot be corrected.

The present invention was proposed to solve the above-described conventional problems. The purpose of the present invention is to dissolve mixed water of raw water and air through dissolution pressure to create nanobubbles containing fine bubbles with a microscopic diameter. It is designed to control the supply of air to the nanobubble generator that is designed to generate nanobubble, and improves nanobubble generation efficiency by stably maintaining an appropriate amount of air that allows nanobubbles to be efficiently generated in relation to the dissolution pressure in the dissolution space. The aim is to provide an air supply control system for nanobubbles.

The air supply control system for nanobubbles according to the present invention for achieving the object of the present invention as described above has a supply port through which mixed water mixed with water and air is supplied and a discharge port for discharging to the outside, and is provided between the supply port and the discharge port. a dissolution means provided with a dissolution space configured to create a dissolution pressure of air relative to the mixed water; a pump means that is driven under the control of a control means that controls the power of the power supply unit and supplies water to the supply port while adding transfer pressure to the water applied from the outside; In the air supply control system for nanobubbles, including an air supply means to supply external air to the water delivered from the pump means to the supply port; It further includes a water level detection means configured to detect the water level of the mixed water applied to the dissolution space of the dissolution means; The control means is characterized in that it operates the air supply means when the level of the mixed water detected by the water level detection means is high based on the set water level, and controls the air supply means to stop operating when it is low.

The air supply control system for nanobubbles according to the present invention, which is configured as described above, detects the level of mixed water in the dissolution space of the dissolution means through the water level detection means, and when the water level is high based on the standard water level set through the control means ( (when the air amount is small), the air supply means is driven to supply external air, which not only increases the dissolution pressure in the dissolution space, but also maintains the amount of air required for dissolution stably, thereby improving dissolution efficiency.

In addition, when the water level of the mixed water in the dissolution space is low based on the set standard water level (when the amount of air is high), the air supply means is turned off to block the air supply from the outside, thereby reducing the air supply in the dissolution space. In addition to preventing supersaturation, it has the effect of stably maintaining dissolution efficiency by stably maintaining the dissolution pressure of the water required for dissolution.

Accordingly, the appropriate ratio of water and air for efficient generation of nanobubbles in the dissolution space is maintained stably, which has the effect of improving nanobubble generation efficiency.
