Description

Nano Bubble proceded water generator

The present invention relates to a nano-bubble water generating device, and more particularly, the compressed air, such as ozone and chlorine dioxide generated by pressurized by a compressor of 10 to 30 nanometers (nm = 1 billionth meter) It is supplied to a diffuser (acid pipe) filled with a porous polymer film (POLYMER) with a large number of pores (pores), and water treatment under high pressure conditions is carried out by oxygen alone generated by pressure release or ultra-fine bubbles mixed with ozone and chlorine dioxide together. It is a nano bubble water generator that generates nano bubble treated water (water containing nano bubbles, bubbled water) of the physical property that maximizes dissolution efficiency, contact efficiency and purification efficiency by continuously supplying and contacting raw water flowing into the tank. ,

In water treatment sites such as fish farms, the raw water is continuously converted into nano-bubble water by pressurized dissolution by circulating contact between nano-sized ultra-small bubbles and ozone or chlorine dioxide selectively mixed with oxygen. Can be supplied to

The nano bubble water generator emits nano-sized bubbles (bubbles) containing compressed ozone or chlorine dioxide at the same time as nano bubbles come into contact with the water to be treated, thereby reducing the gas-liquid contact area with the water. It can be maximized to combine with this material in water to achieve high sterilization and cleaning effect, and to increase the amount of dissolved oxygen in the nano bubble treated water by increasing the time the bubble stays in the treated water. To improve the growth of fish without

In addition, by dissolving harmful chemical substances by powerful chemical reaction of hydroxyl radical (OH) radicals generated by mixing ultraviolet rays in addition to ozone or chlorine dioxide, sterilization, deodorization, and water purification of the treated water are converted into clean water. Can be supplied, eliminating the need for frequent water changes at the water treatment site,

In particular, the present invention is a self-pressing effect of nano-sized ultra-fine bubbles stabilized as a nano bubble (bubble) without the dispersion of gas, such as oxygen, ozone, chlorine dioxide in the nano-bubble of the gas combined with oxygen and ozone or chlorine dioxide Nano bubbles (bubbles), which have characteristics, can continue to exist in the water for several months, so that water purification can be continuously performed due to the generation of strong radical hydroxyl radicals generated when the ultra-foam bursts and disappears.

In the various types of fish farms, which are formed to grow various fish as well as freshwater and marine cage farms and land farms, various diseases and parasites are caused by water pollution, but due to economic and technological limitations, the improvement of water quality is fundamental. It is not implemented and stays in secondary treatment such as microbial or antibiotic administration.

In particular, various types of fish are kept in high density in a limited space, and the water quality deteriorates due to various pollutants such as fish droppings and lack of oxygen supply, and the pollution of the water becomes serious day by day, resulting in high mortality of the fish and polluting the surroundings. Let's go. In fish farms, water in the farms needs to be purified or drained to prevent disease and promote the growth of fish, but it is cumbersome, costly, and changes in the environment caused by the change of the waters may impede the growth of fish or cause death. For this reason, all fish farms need an efficient oxygen supply system to continuously supply clean purified water through the whole refining or circulating filtration, or to maintain a constant dissolved oxygen (DO) of the water in the farm.

Conventional farms supply oxygen using various types of diffusers, aberrations, aerators, etc., but the bubble size is so large that the oxygen dissolution rate in the water is very low and the oxygen supply is not economical and effective compared to the power consumed. There is this.

     In addition, the general method for disinfecting water in farms and improving water quality by simply using drugs such as ultraviolet rays, ozone, or restricted chlorine is not effective in purifying the fish. Therefore, there is an urgent need for water purification measures that can prevent water pollution without damaging fish.

 Sterilization and disinfection using ultraviolet light is not only effective for some organisms, but also has a short wavelength of ultraviolet light, which makes it difficult to function in a cloudy state and does not completely dissolve organic materials.

Farms using ozone, which has the ability to oxidatively decompose various odorous substances including ammonia (NH ₃ ), hydrogen sulfide (H ₂ S), methane (CH ₄ ), etc., and to sterilize bacteria and viruses with strong sterilization. The sterilization method of water has strong oxidizing power to inhibit trihalomethanes (THMs, Trihalomethanes), improve filtration performance, and have great disinfection ability against microorganisms that are not inactivated by chlorine. Due to the large bubble and short underwater residence time, the gas-liquid contact area is small, and 60 ~ 70% or more of the total ozone supplied cannot react and there is no residual effect. Have a disadvantage

 In addition, chlorinated disinfectants emit irritating odors despite their strong bactericidal effects and are characterized by trihalomethanes (THMs, Trihalomethanes), halo acetonitriles (HANs, Haloacetonitriles), halo ketones (HKs, Haloketones), halopocrin, It generates carcinogenic by-products such as haloacetic acids (HAAs) and chlorophenols, and is highly toxic, which can lead to the death of farmed fish, and bacteria can re-grow after disinfection. There is a limit.

      However, since chlorine dioxide is stable in solution and reacts slowly with water, it can maintain sterilizing power over a wide pH range and it is emerging as an alternative medicine for chlorine disinfectant because there is no by-product, but it is commercialized due to the change in properties over time and movement. There is a hard problem.

As a method for simultaneously securing the dissolved oxygen and water quality management, which are essential for the growth of fish, the bubble generator is used to generate fine bubbles in the water to supply oxygen to secure dissolved oxygen and to improve water quality. There is a way of giving up.

Normal bubbles (bubbles) rise and rupture to the surface, and microbubbles are microbubbles with a diameter of 50 microns (μm) or less. They are suspended for several hours and then dissolved in water, but nanobubbles are smaller in diameter than microbubbles. It is possible to exist for a long time in water as a bubble of 100 nm.

Microbubbles with a diameter of 50 μm or less are capable of supplying dissolved oxygen and performing only water purification functions, whereas micro bubbles having a diameter of 1 μm (1 micrometer: 1 millionth of a meter) or less are nano bubbles. In addition, there is a difference that can promote sterilization or deodorization function and the physiological activity of fish, but there is a problem that the conventional nano-bubble is extinguished in a short time because it is very unstable physically.

However, since the conventional nano bubble water generator cannot generate nano bubbles (bubbles) of improved physical properties to effectively trap gas such as oxygen or ozone for long time storage, the present inventors stabilized in the field of a large fish farm. Easily create nano bubbles (bubbles) to enable long-term presence of nano bubbles (bubbles), but improve oxygen dissolved and sterilization effects by incorporating oxygen and ozone or chlorine dioxide with sterilizing effects into bubbles with purification effects As a method of making it possible to develop a nano bubble water generator for water treatment containing oxygen, ozone or chlorine dioxide and to produce a stabilized nano bubble treated water.

It can be maintained for several months to simultaneously provide the dissolved oxygen supply, sterilization and antibacterial effect, insect repellent effect, cleaning effect, adaptability to fish environment change and growth improvement, and reduction of operating cost due to energy saving of water saving and power saving. Can be.

A chlorine dioxide generator 25 for supplying chlorine dioxide gas to the gas supply line C is connected and connected to the mixed gas supply line B with the chlorine dioxide gas supply line F, respectively, and the mixed gas supply line B ) Is installed at the bottom of the nano-bubble water generating tank 30 and connected to the diffuser 40 which generates nano-bubbles, and optionally, compressed air alone or a mixed gas of air and ozone, air and chlorine dioxide, if necessary. Supply to the bubble water generating tank 30,

On the lower side of the front end of the nano-bubble water generating tank 30, an ultraviolet sterilizer 11 for sterilizing the incoming raw water, a filter 12 for filtering foreign substances, a raw water suction pump 13, and a flow control valve (electromagnetic valve) 14 ) Is sequentially mounted to form a raw water supply line (A) for suctioning the raw water to be supplied to the tank,

Contaminated water, such as fish farms, which are pretreated in the raw water supply line (A) at the site of the processing site such as fish farms by the control of the control panel 20, are supplied to the nano bubble water generation tank 30 by a suction pump 13. When the raw water is recycled by suction and purifying and discharged again by using the discharge pump 51, the mixed gas supply line B is supplied to the mixed gas supply line B in the process of passing the nano bubble water generation tank 30.

To supply sufficient dissolved oxygen to fish farms and to improve the water quality, and to promote the growth of fish by activating the modified water (nano bubble water) The.

The compressor 21 is a conventional compressor for providing compressed air to the nanobubble water generating tank 30, and the diffuser at the bottom of the nanobubble water generating tank 30, such as an air unit 22 mounted at a rear end thereof, 40 is connected to the gas pipe line, but an additional ozone supply line (C) and chlorine dioxide supply line (F) for supplying ozone supplied from the ozone generator (23) are respectively formed as a rear pipe line of the air unit (22). And a mixed gas supply line B for supplying air (oxygen) or a mixed gas of air and ozone, air and chlorine dioxide to the nanobubble water generating tank 30 at high pressure through an acid pipe 40 at the end of the gas pipe. The compressor 21, the ozone generator 23, and the chlorine dioxide generator 25 are each connected to and controlled by the control panel 20 operating with a predetermined program, and the nanobubble water generator 100 operates as a whole. Power By being configured to be supplied through a separate generator (24) can drive the nano bubble generator can also place a commercial power is not supplied.

The air unit 22 is equipped with an air filter and a pressure reducing valve (not shown), and decompresses the high-pressure compressed air passing through the air filter with a pressure reducing valve. It is preferable to supply to.

In addition, ozone, which is a gas that sterilizes as an allotrope of oxygen, is generated in the ozone generator 23, and chlorine dioxide gas having strong sterilization and deodorization power after ozone is generated by a conventional method in the chlorine dioxide generator 25, respectively. It is preferable to install a flowmeter and a pressure gauge to check whether ozone or chlorine dioxide gas of the concentration necessary for supplying the bubble water generating tank 30 is supplied.

On the other hand, the raw water supply line (A) formed on one side of the nano-bubble water generating tank 30, the ultraviolet sterilizer 11 for sterilizing the incoming raw water, the filter 12 for water purification to filter the foreign matter, and the motor attracted to the power source A suction pump 13 and a flow regulating valve 14 which pressurize and pump water are sequentially mounted on the piping line to filter out various foreign substances and sterilize harmful bacteria in the process of sequentially passing the piping line by sucking the raw water to be treated. The purified water is supplied to the nano bubble water generating tank 30. The ultraviolet sterilizer 11 is a conventional ultraviolet sterilizer for sterilizing water by irradiating ultraviolet rays using a UV lamp (not shown). The sterilization and filter 12 for water purification prevents the inhalation of foreign substances such as sand, which may hinder the generation of nano bubbles (bubbles).

In addition, the nano-bubble water generation tank 30 is an airtight tube (AIR VENT) 31 in which air is communicated to the upper end of the closed cylindrical water tank (DRAIN) 32 to discharge the foreign matter precipitated by filtering the lower end (DRAIN) 32 and Valves 33 for opening and closing the discharge pipes are formed, respectively, and the diffuser 40 made of the ultrafine pores of the nanofilm (polymer film) 41 is embedded in the tank bottom.

The diffuser 40 for supplying the air or a mixture of air and ozone, air and chlorine dioxide in water may be formed in various ways in addition to the column in the form of a pipe,

In the embodiment of the present invention to form a diffuser 40 in the form of a membrane using a nano-film 41, which is a very thin film (polymer) having a thin thickness and high porosity and has a large surface area and excellent surface permeability. ,

Nano-film 41 to be applied to the present invention is formed in a number of pores 42 of 10 to 30 nanometers (nm = 1 billionth meter) invisible to the naked eye formed on a non-porous substrate The microfibers 43 are formed in a bubble structure (web structure) so that there is no decrease in fiber strength, so that clogging of pores does not occur, so the air permeability (gas permeability) is very excellent, so that the fine fibers are fine compared to the conventional diffuser. It is possible to generate a bubble (nano bubble) stably and efficiently, the nano-bubbles 44 formed in this way can maximize the gas-liquid contact area with the raw water supplied into the tank by excellent dissolution efficiency, contact efficiency, and purification efficiency. This will maximize the supply of dissolved oxygen and sterilizing ozone or chlorine dioxide, which are essential for fish growth.

And the air flowing in and out of the air vent (AIR VENT) 31 in the nano-bubble water generating tank 30 is absorbed and compressed by the pump water pressure by the action of the pressure difference,

Gas (air or air and ozone, mixed gas of air and chlorine dioxide) mixed in the nano bubble (bubble) flowing into the diffuser 40 is contacted with the incoming raw water in the form of a bubble so that oxygen, ozone or chlorine dioxide is dissolved. As a function of the activated bubble water to produce nano-bubble water as small as invisible, the nano-bubbles (diameter less than 1μm) produced in the present invention has a contact surface more than 100 times compared to microbubbles (diameter 50μm or less). In contact with bacteria or bacteria, the sterilization effect is greatly improved.

That is, the fine bubbles 44 generated by the nano-film 41 having a nano-pore structure formed in the diffuser 40 react with the raw water to rise and react within the nano-bubble water generating tank 30 to be visually identified. Nano bubbles (bubbles) are generated, which are caused by the forces compressing the gas inside the bubbles (bubbles) with a spherical interface, although the bubbles in the bubbles appear to disappear. As the bubble is compressed by the self-pressing effect of ultra-fine bubbles, ions are concentrated on the surface of the bubbles, and the concentrated ions act as shells surrounding the bubbles, preventing the gas inside the bubbles from scattering. As a result, the scattering of the gas in the nano bubbles (bubbles) is suppressed and stabilized as nano bubbles (bubbles).

After all, the present invention is stabilized as a nano bubble (bubble) without the dispersion of gas such as oxygen, ozone, chlorine dioxide in the nano bubble (bubble) by the self-pressing effect of the ultra-sized bubbles of nano-size, so that oxygen, ozone, chlorine dioxide Nano bubbles (bubbles), which combine the characteristics of the combined gas, can continue to exist in the water for several months, and in fish farms, ultra-foam bubbles can be generated only by the inflow of nano bubble water mixed with oxygen or ozone alone or in the form of mixed bubbles. It is to be able to continuously perform the water purification action according to the generation of a strong energy hydroxyl radical generated when bursting and extinction bar nano-sized bubble (bubble) according to an embodiment of the present invention is sprayed in the flowing water small buoyancy Bubbles can be delivered for more than 1 km.

The nano-bubble water generated as described above is formed with a nano-bubble water supply line (D) in a direction opposite to the raw water supply line of the nano-bubble water generation tank 30, and thus the nano-bubble water generated in the nano-bubble water generating tank 30. Pressurized pump discharged to the outside of the water tank 30 through the injection nozzle 50 connected to the end of the nano-bubble water supply line (D) using the discharge pump 51, the positive pressure in the nano-bubble water supply line (D) Bypass line (E) equipped with a valve (Relief valve) 60 is connected in parallel to keep the pressure in the pipe line constant within the set range, impurities such as debris is nano-bubble generating tank 30 It is discharged out of the nano-bubble water generating tank 30 through the discharge pipe 32 and the valve 33 connected thereto.

In addition, in the present invention, the operation of the ozone generator 23 for supplying the mixed air mixed with ozone and the chlorine dioxide generator 25 for generating chlorine dioxide may be selectively and limitedly operated as necessary so as not to overlap each other. .

The nano bubble water generator 100 according to the present invention is floated in the water by using a buoy wire 70 equipped with a buoy 71 so as not to sink in the water, and using the suction pump 13. While contaminated raw water, such as fish farms, passes through the nano bubble water generation tank 30 and reacts with the nano-sized microbubbles 44 emitted from the diffuser 40 to mix oxygen or ozone (bubbles). Nano bubble water containing the circulating filtration method can be continuously supplied to the fish farm and the like to the injection device 50, the nano bubble water supplied in the state that oxygen and ozone or chlorine dioxide is contained in the bubble due to the charging effect Since it is stabilized, it can maintain ozone in water for a long time even in fish farms under conditions of normal temperature and normal pressure, and in addition to the gas dissolution effect of ultra-fine bubbles, Due to the combined synergistic effect of purifying, sterilizing and strengthening the immunity of fish by increased dissolved oxygen due to the hydroxyl radical mixed with air and ozone or chlorine dioxide, which is caused by the bursting of air, it is significantly improved compared to the prior art with low power consumption. The water quality improvement effect can be realized.

         In particular, the aberration 80 is installed on the surface of aquaculture farms and the like as shown in FIG. 3, and the rear end of the aberration 80 includes an injection device 50 connected to a pipe (hose) by the nanobubble water generator 100. To be placed below the surface of the water in the forward direction) and a large bubble (bubble, aberration generating bubble) that is generated in the process of stirring the water, such as fish farms according to the rotation of the aberration (80) blades When ejected in a way to slowly rise below the water surface to prevent the phenomenon that the ultra-fine nano bubbles (bubble) is broken by a relatively large bubble generated in the aberration 80,

      The large bubble (bubble) generated by rotating the blades of the aberration 80 is supplied with oxygen to surface water such as fish farms to increase the amount of dissolved oxygen and purify the water quality, and ultra-fine by driving the nano bubble water generator 100. Nanobubble containing nanobubbles (bubble) is rapidly floated out of the water so that it is not affected by large bubbles, so that it is slowly pumped to the surface by means of pressure pumping and spraying in water to dissolve at room temperature. Effect and dissolved oxygen enhancement effect are combined to synergistically combined.

      In addition, in the present invention, the water flow generator for supplying oxygen to the surface water is described mainly on the aberration 80, but the air bubbles are also ejected to the rear end of the submersible pump (including the air bubble forward direction), the injection method by the injection nozzle It is preferable to improve the water quality of aquaculture farms by spreading and supplying the nano bubble (bubble) evenly over the upper layer and the lower layer in the water by varying and supplying the silver injection position (water depth).

      In addition, the nano-bubble water generating device 100 according to the present invention may be installed on the land without using the buoy wire 70 according to the installation conditions and may be installed using a long hose injection device, as shown in FIG. Only the ozone generator 23 may be connected to the air unit 22 for supplying oxygen (oxygen), or only the chlorine dioxide generator 25 may be used without the ozone generator 23.

       In addition, in the present invention, unlike other chlorine disinfectant disinfectants with strong oxidation, sterilization, deodorizing power does not produce carcinogenic organic substances such as trihalmethane (THMs), halo acetic acid (HAAs), halo acetonitrile (HANs) Chlorine dioxide generator 25 for generating chlorine dioxide of physical properties is an aqueous solution of chlorine dioxide in addition to the method of additionally administering chlorine dioxide gas to the micro-bubbles generated by the method using a nano-porous structure nano film as in the embodiment of the present invention May be administered to fish farms.
