[0001] APPARATUS OF MANUFACTURING OZONIC WATER WITH HIGH CONCENTRATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozonated water producing apparatus, and more particularly, to an apparatus for manufacturing and supplying ozone water concentrated at a high concentration, that is, a high ozone water production system (HOPS).

Ozone is a highly potent antimicrobial substance that can be usefully used in the food industry by inactivating microorganisms through oxidation and decomposing into harmless oxygen.

Ozone has high oxidizing power after fluorine and has high reactivity with organic and inorganic materials and has a sterilizing, deodorizing and decolorizing effect, so that microorganisms are killed much faster than chlorine, there is no need to adjust the pH during the treatment and ozone sterilization This method is more inexpensive than other processing methods, and can be sterilized not only on the surface of the food but also on the surface of the food.

Despite the function of ozone water, ozone has a microbial sterilization effect, and even when the concentration of ozone gas is 0.1 ppm, irritating nose and throat, and toxicity that can cause headache at 1 ppm, It is because the ozone generator should be equipped with an ozone gas decomposition device and a lid of ozone water washing tank so that the concentration of ozone gas in the workplace increases.

For this reason, technologies for converting ozone gas into ozonated water and using it in domestic and industrial facilities have been developed.

However, according to the existing ozonated water production method, the dissolution rate is only about 7 to 30%, so that a lot of surplus ozone gas is generated and unnecessary human and other substances are adversely affected due to strong oxidizing power of ozone .

It is an object of the present invention to provide a high concentration ozonated water producing device capable of minimizing surplus ozone gas and maximizing dissolution rate of ozonated water.

The ozonated water supply device according to the present invention includes a housing for forming an outer appearance, a mixing unit for mixing ozone water supplied with water from outside and combined with ozone gas through circulation of water, A cluster separator for separating the clusters of water by an electric field into which the water from the mixing unit flows by the pump, and a line mixer for mixing the ozone gas generated from the ozone generator into the water passing through the cluster separator. .

Here, the mixing unit may include a water tank provided to allow water to flow through the water supply pipe, an exhaust pipe for discharging excessive ozone gas to the outside after mixing, and a drain hole for discharging the mixed ozonated water, A mixing tank provided with a diameter smaller than that of the water tank and formed with a plurality of holes and a rotation motor for providing power for rotating the mixing tank,

The water tank is provided with a water level sensor, and the water supply pipe is provided with a water supply valve. When the water level exceeds a predetermined threshold value, the water level sensor detects the water level and controls the water supply valve to shut off water supply.

The excess ozone gas discharged through the exhaust pipe is decomposed and discharged by the ozone treatment unit connected to the exhaust pipe,

The ozone treatment unit may include a heating unit for heating ozone gas passing through the exhaust pipe by heating the exhaust pipe, a filter for filtering the ozone gas exhausted to the exhaust pipe, and an exhaust fan for exhausting the filtered ozone gas to the outside ; As shown in FIG.

The cluster separator includes a separator for energizing the path of the introduced water, and an electrode for applying an electric field to induce an electric field,

And the electrode rod has at least one bent portion.

According to the present invention,

First, by dissolving clusters of water by using an electric field, it is possible to maximize the dissolution rate of ozone water by widening the contact surface between ozone gas and raw water with the same amount of ozone, thereby making it possible to produce ozone water at a high concentration and supply ozone water at a large capacity.

Secondly, the contact area increases due to the bubbles generated through the gas-liquid mixing part, and ozone gas can be dissolved well in the water.

Third, energy consumption is reduced due to the reduction of electricity consumption, manufacturing cost, and the like, compared with a conventional method in which ozone is injected into a tank in order to raise the concentration of ozone water.

Fourth, it is eco-friendly by reducing the amount of excess ozone gas and discharging it after purification.

Fifth, it is possible to prevent the equipment from being damaged by blocking the reverse flow of the raw water by the backflow prevention unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described more specifically with reference to the accompanying drawings, but the description of the already known techniques will be omitted.

2 is a schematic view showing the internal construction of the ozonated water producing apparatus according to the present invention, and Fig. 3 is a sectional view showing the construction of the lower part of the ozonated water producing apparatus according to the present invention. Respectively.

1 to 3, an ozone water producing apparatus 10 according to the present invention includes a housing H, an ozone generator O, a filtering unit 100, a cluster separator 200, a pump P, A mixing unit 300, a backflow prevention unit, a line mixer 500, a ozone treatment unit 160, and a control unit C, and the like.

The housing H forms an outer appearance and includes a filtering unit 100, a cluster separation unit 200, a pump P, a gas-liquid mixing unit 300, a backflow prevention unit, a line mixer 500, And an operation switch S is provided on the outside.

The ozone generator O is a structure for supplying ozone gas into the housing H in a configuration for generating ozone gas.

The filtering unit 100 contained in the housing H may be provided in a plurality of ways. In order to purify the wastewater, the inflow water may pass through the filtering unit 100. In an environment in which purified water is introduced, .

The pump P operates in accordance with the signal of the controller C under the control of the operation switch S to draw water and supply it to the gas-liquid mixer 300. The cluster separator 200 has a gas- (300), and reduces the cluster unit of water supplied.

Water is formed by a large number of water molecules forming clusters. Studies have shown that as the cluster size gets smaller, the water tastes better, and the solubility, osmolality, and vitality become better. In this work, water is not simply combined with ozone gas, but the clusters are reduced by the cluster separator, and the intensity of the electric field in contact with the water and the contact time are maximized to change the inherent physical properties such as minerals contained in the water And maximize the function of ozone water by increasing the solubility, metabolism, osmotic power, activation power and so on.

Referring to FIG. 4, the cluster separator includes a separator plate 210, a booster 220, an electrode bar 230, and the like.

The separation plate 210 is formed in a horizontal direction in the path of the water for forcing the strength of the electric field in contact with the water by forcing the path of the water flowing through the flow path.

The positive pole of the booster 220 is connected to the electrode rod 230 and the negative pole of the booster 220 is connected to the cluster separator to boost the common electricity 220V to a high voltage, It causes a classic badge. The electrode bar 230 is composed of a stainless steel bar to which the positive pole of the booster 220 is electrically connected, and a ceramic layer that surrounds the stainless steel bar. The electrode bar 230 is spaced apart from the inner surface of the cluster separator and is disposed so as not to be in contact with the separator plate 210. The electrode bar 230 may be formed in a simple bar shape, Quot; L " or " d "

The gas-liquid mixing unit 300 is configured to mix the ozone gas supplied from the ozone generator O and the water that has passed through the cluster separation unit 200 at a high concentration, and the ozone gas is supplied through the backflow prevention unit.

The backflow prevention portion includes the backflow prevention valve 410, the auxiliary backflow prevention unit 420, and the bypass means.

The check valve 410 is provided to prevent the raw water from flowing back to the supply pipe to which the gas is supplied. 5 and 6, it is not limited to this example.

The body 411 has a generally cylindrical outer shape with a stepped cylindrical shape and a receiving space 412 is formed in the upper end and a loading port 430 which is smaller in inner diameter than the receiving space 412 is connected to the receiving space 412 at the lower end .

A male thread is formed on the upper and lower parts of the body 411, and the lower part of the body 411 is threadedly engaged with the line through which the raw water passes.

The head portion 440 has a substantially cylindrical outer shape with an upper end opened and a lower portion formed with a female screw so as to be screwed on the upper portion of the body 411. A female screw is connected to the opening in the body 411 An inlet is formed. Accordingly, when the head part 440 is coupled to the body 411, the opening of the head part 440, the inlet port, the receiving space 412, and the inlet port 430 are connected in order.

Here, the cap 450 may be screwed to the upper end of the head part 440 so as to be connected to a supply pipe for supplying gas.

And includes a moving piece 460 and a spring 470 for opening and closing the inlet.

The moving piece 460 is formed to have a substantially hemispherical shape with an outer diameter corresponding to the inner diameter of the accommodation space 412 and a lower end formed to be smaller than the outer diameter of the upper end. One passage 460a is formed.

The moving piece 460 is inserted into the receiving space 412 and moves up and down.

Accordingly, when the moving piece 460 is inserted into the accommodation space 412, the inlet port and the inlet port 430 are connected to each other by the passage 460a formed in the moving piece 460. [

The spring 470 is fitted to the lower end of the moving piece 460 and inserted into the receiving space 412.

Accordingly, the spring 470 pushes the moving piece 460 upward, so that the moving piece 460 normally keeps the inlet port shut off.

Here, the moving piece 460 may be formed such that the surface area of the lower end is larger than the surface area of the upper end, and grooves are further formed at the lower end of the moving piece 460. When the raw water is filled in the receiving space 412 in a state where the moving piece 460 is in close contact with the inlet, the upper and lower sides of the moving piece 460 are pressure balanced. This is because the raw water is also filled in the upper part of the moving piece 460 through the passage 460a of the moving piece 460. At this time, since the surface area of the lower end of the moving piece 460 is larger than the upper surface area of the moving piece 460, the raw water pushes the moving piece 460 upward so that the moving piece 460 moves downward.

If the surface area of the upper end of the moving piece 460 is larger than the surface area of the lower end portion, the pressing force of the raw water lower than the force pushing the moving piece 460 upward becomes larger so that the moving piece 460 instantaneously moves downward The inlet may be opened instantaneously by movement.

However, in the present invention, since the surface area of the lower end of the moving piece 460 is larger than the surface area of the upper end, the force of pushing the raw material upward above the force of pushing the moving piece 460 downward is large.

Further, since the outer diameter of the moving piece 460 corresponds to the inner diameter of the receiving space 412, it is possible to prevent the moving piece 460 from flowing back and forth, right and left. Accordingly, even if an impact or vibration is applied from the outside, the moving piece 460 is prevented from flowing back and forth, right and left, thereby making it possible to firmly block the opening of the inlet.

7, the auxiliary backflow prevention unit 420 is connected to the ozone generator O to supply the gas to the backflow prevention valve 410, maintains the pressure of the supplied gas at a constant level And includes a main body 421 and a buoyancy valve 422. The main body 421 and the buoyancy valve 422 serve to shut off the reverse flow of the raw water to the gas supply means.

The main body 421 has a substantially long tank shape having an internal space of a predetermined size formed therein and a gas inflow portion 423 through which gas is injected to be connected to the ozone generator O is provided at an upper end, A gas supply unit 424 is provided so as to be connected to the gas supply unit 410.

The main body 421 is provided with a raw water inflow portion 425 connected to a line at a lower end of the main body 421 so that raw water flows into the lower portion of the main body 421, An overflow portion 426 for discharging raw water out of the main body 421 is provided. Accordingly, due to the overflow portion, a certain range of pressure can be formed inside the main body 421, so that the gas can be supplied smoothly.

The buoyancy valve 422 is formed in a substantially spherical shape of a light material floating in water and inserted into the interior of the main body 421.

When the raw water flows into the lower end of the main body 421, the buoyancy valve 422 is lifted by the raw water. When a predetermined amount of raw water flows into the main body 421, the raw water is supplied through the overflow portion 426 And discharged out of the main body 421.

When the pressure of the raw water suddenly increases, the raw water rapidly rises to the inside of the main body 421, and the buoyancy valve 422 is brought into close contact with the upper end of the main body 421 to cut off the upper end of the main body 421. Therefore, by blocking the upper end of the main body 421, the buoyancy valve 422 can prevent the raw water from flowing back to the gas supply means.

If the pressure of the gas suddenly increases, the raw water is discharged out of the main body 421, the buoyancy valve 422 moves downward, and the gas can be discharged out of the main body 421 through the overflow portion 426 have. Accordingly, it is possible to prevent the inside of the main body 421 from being damaged due to the high pressure.

The overflow unit 426 uses a well-known technique, and a detailed description thereof will be omitted.

The bypass means includes a check valve 480 and a bypass valve 490 formed at the front end and the rear end of the check valve 410. In order to actively regulate the concentration and capacity of the ozonated water, the water is bypassed by shutting off the flow by a check valve (480) and forming a bypass pipe between the bypass valve (480).

8 to 12 show the gas-liquid mixing unit 300, wherein the gas-liquid mixing unit 300 mixes the introduced water and the ozone gas at a high concentration.

Liquid mixing unit 300 includes a main body 310, a supply unit 320, a mixed aquatic function unit 330, a discharge unit 340, a bubble generation unit 350, a pressure measurement unit 360, a pressure reducing valve 370, .

The main body 310 has a substantially cylindrical shape with a closed upper end and a lower end, and a valve V is installed at the lower end to remove the residues therein.

The supply unit 320 includes a supply pipe 321, a pressurizing pump 322, and a flow control unit 323.

The supply pipe 321 is installed horizontally through the main body 310 and the body 331 to be described later in a substantially pipe shape. At this time, a valve (not shown) may be installed at the end of the supply pipe 321 to remove the pressure of the supply pipe 321 when the pressure of the supply pipe 321 rises above the allowable pressure.

The pressurizing pump 322 is connected to the supply pipe 321 and is disposed outside the body 331 and supplies a mixture of water and ozone gas to the supply pipe 321.

The flow rate regulator 323 is connected to the supply pipe 321 and is disposed between the pressurizing pump 322 and the main body 310 and adjusts the supply amount of the mixture and the injection pressure of the mixture.

The mixed aquatic function portion 330 includes a body 331, a foam generating portion 332, a first jetting portion 333, a perforated plate 334, a leg 335 and a second jetting portion 336.

The body 331 is formed in a substantially cylindrical shape having a closed upper end and a lower end and is smaller than the body 310 and is disposed inside the body 310. A leg 335 is provided between the lower end of the body 331 and the body 310, And is disposed in the middle of the inside of the main body 310.

The foam generating portion 332 is provided on the inner ceiling of the body 331 with a mesh M of a substantially cylindrical shape. A description thereof will be described later.

Here, the foam generating unit 332 may be a perforated plate (not shown), which uses the mesh M but has the same hole or holes of different sizes.

The first jetting section 333 is configured such that a vertical tube 333a connected to the supply tube 321 is disposed inside the body 331 and a rotary nozzle 333b is provided at the upper end of the vertical tube 333a, The nozzle 333b is inserted into the center of the mesh M. At this time, when the mixture is supplied to the mesh (M) by receiving the mixture from the supply pipe (321), the mixture passes through the mesh (M) and bubbles are generated. As a result, the contact area of the mixture becomes large, and the ozone gas dissolves well in water.

The perforated plate 334 is formed with a plurality of holes in a substantially disc shape, is fitted in the vertical tube 333a, and is provided at the lower end of the mesh M. That is, the bubble generated in the bubble generator 332 falls down through the hole of the perforated plate 334, so that the residence time of the bubble can be extended, and the bubble fades to generate mixed water. Thus, by extending the bonding time between the gas and the liquid, the gas is well dissolved in the liquid.

The second jetting section 336 is disposed below the body 331, and a plurality of the second jetting sections 336 are provided around the body 331. That is, the mixed water dropped through the perforated plate 334 is collected at the bottom of the body 331, and the mixed water collected at the bottom is injected into the bubble generating unit 350 to be described later through the second jetting unit 336. A description thereof will be described later.

Here, the second jetting part 336 may be formed with a plurality of jetting nozzles or a slit shape in the vertical direction in order to widen the jetting range. In addition, the second jetting section 336 may be formed toward the bubble generating section 350, which will be described later.

One end of the discharge part 340 is installed around the lower part of the main body 310, connected to the main body 310, and bent upward. The discharge unit 340 is provided with an exhaust unit 341 at an upper end of the discharge unit 340 to discharge surplus gas remaining in the body 310.

The bubble generating unit 350 includes a plurality of holes formed in a rectangular perforated panel and a plurality of holes are provided around the upper portion of the body 331 to correspond to the second jetting unit 336. As a result, the mixed water sprayed from the second jetting part 336 collides to generate bubbles, and the contact area of the mixed water increases, so that the gas melts once more into the mixed water, thereby producing high-quality mixed water.

The pressure measuring unit 360 is installed at the upper end of the main body 310 and measures the internal pressure of the main body 310.

The pressure reducing valve 370 is disposed outside the main body 310 and has one end connected to the upper end of the main body 310 and the other end connected to the supply pipe 321 to open and close the upper connecting portion of the main body 311. That is, when the pressure measured by the pressure measuring unit 360 exceeds the set pressure 4K, the pressure reducing valve 370 is opened to allow the internal pressure of the main body 310 to be bypassed to the supply pipe 321, The pressure drops.

In addition, the ozone treatment unit 160 is further configured to minimize excess ozone gas discharged through the exhaust port 341 of the discharge unit 340 described above.

As shown in Fig. 15, the ozone treatment section 160 is composed of a hissing member 161, a filter 162, an exhaust fan 163, and an insulator 164.

The present invention minimizes the emission of harmful gas by heating ozone gas which is vulnerable to heat and discharging it. That is, a stainless steel material heater 161 which surrounds an exhaust pipe (not shown) formed from the exhaust port 341 is formed and connected to a heat transfer device (not shown) by a hot wire to heat the heat transfer material 161 And the ozone gas passing through the exhaust pipe is heated and decomposed by heating the exhaust pipe through which the heat passes.

The heating member 161 has a heating rod 161a which is connected to the electric heating device by a hot wire and is in contact with the exhaust pipe to transmit heat to the exhaust pipe and a cylindrical heating pipe 161b surrounding the exhaust pipe with a diameter larger than that of the exhaust pipe The other end of the heating rod 161a is in contact with the heating pipe 161b so that the heat of the heating rod 161a is transmitted to the heating pipe 161b so that the inside of the heating rod 161a surrounding the exhaust pipe It serves to trap heat in the space, so that sufficient heat transfer is made to the exhaust pipe.

The ozone gas is decomposed to the maximum by applying heat of about 200 to 300 ° C., and the ozone gas is filtered again through the filter 162 disposed at the rear end of the ozone gas. The heat of the heating tube 161 b is transmitted It is preferable that an insulator 164 is provided between the heating pipe 161b and the filter 162 to cut off.

The filter 162 may be variously employed, preferably by applying a carbon filter so that ozone gas is adsorbed by the activated carbon.

Excess ozone gas passed through the slow heating member 161 and the filter 162 is finally discharged to the outside by the suction force of the exhaust fan 163. [

In this way, a UV lamp may be provided instead of the sush heating member, and the ozone may be burned by the irradiated UV lamp.

On the other hand, as shown in FIG. 10, the second jetting section 336 may be formed to be inclined toward the bubble generating section. Accordingly, the ozone water sprayed from the second sprayer 336 is uniformly sprayed to the bubble generator 350.

Here, as shown in FIG. 11, the perforated plate 334 may have a plurality of holes having different sizes. Accordingly, the mixed water and bubbles generated through the mesh can stay together with the perforated plate 334 while descending.

As shown in FIG. 12, a plurality of holes having different sizes may be formed in the bubble generator 350. As a result, the mixed water and the foam sprayed from the second sprayer 336 pass through the bubble generator 350, and the mixed water bubbles once again, and the sprayed foam passes as it is to maximize the contact area, A larger amount of residual gas gas can be melted to produce a high quality mixed water.

The mixed ozonated water passes through the line mixer 500 and is stored in the internal or external reservoir or directly supplied.

Referring to FIGS. 13 and 14, the line mixer 500 includes a reference axis 510 and a plurality of mixing members 520.

The line mixer 500 further enhances the ozone gas dissolution rate of the ozonated water mixed through the gas-liquid mixer. The ozonated water increases the contact area of the ozone gas and the contact time while passing through the plurality of mixing members 520, Thereby increasing the dissolution rate of the gas.

That is, a plurality of mixing members 520 are inserted into the reference shaft 510 in the line mixer. The plurality of mixing members 520 are generally composed of a rotating plate and a perforated plate, It is also better to mix by rotation. Such a mixing member can be changed into various forms capable of prolonging contact area and time so that ozone gas can be dissolved well in water.

As an example of the mixing member, one rotating plate 520a and one perforated plate 520b are illustrated in Fig. The illustrated rotating plate 520a has holes formed therein to allow the rotating plate 520a to rotate while passing through the fluid. The illustrated perforated plate 520b has a plurality of small holes to allow the fluid to pass through the narrow holes, .

Meanwhile, the high concentration ozonated water producing apparatus of the present invention further includes a raw water heat exchanger 600 as shown in FIG.

The raw water heat exchanger 600 is formed on the side piping through which the raw water flows, and serves to lower the temperature of the raw water through heat exchange with the raw water.

The lower the temperature, the larger the ozone concentration of the ozone water, which contributes to the production of ozone water at a higher concentration.

For this purpose, the raw water heat exchanging part 600 has an internal space and includes a heat exchange pipe 610.

The heat exchange pipe 610 is connected to the inlet and outlet pipes and is formed in a spiral shape so that the contact area with the inner space of the raw water heat exchanging part 600 is widened and water is introduced into the inner space and rapidly cooled .
