The present invention relates to an ozone sterilizing water production apparatus capable of adjusting the ozone concentration using the ozone diffuser method, more specifically, ozone using the ozone diffuser method that can adjust the dissolved ozone concentration by adjusting the pressure inside the container discharged ozone water. It relates to a sterilizing water production apparatus.

In general, ozone sterilizing water production apparatus for producing ozone dissolved water, that is, dissolved ozone water is a device configured for the purpose of obtaining the expected effects such as purification power, sterilization power by ozone by incorporating ozone into water. The ozone sterilizing water production apparatus is classified into a pressurized injector method, an acid generator method, a venturi injector method and the like according to the generation method of dissolved ozone water.

1 is a schematic configuration diagram of an ozone water generating device adopting a pressurized injector method.

Referring to FIG. 1, the apparatus for generating ozone water of a pressurized injector may include an air pump 1 for forcibly transferring the sucked external air to a destination, and converting oxygen in the air transferred through the air pump 1 into ozone. An ozone generator (3) installed on the hazardous path and having an ozone generator (2), a mixing section (5) for mixing ozone coming out of the ozone generator (3) and water supplied from the water source side (4), and It is provided with an electromagnetic valve 7 installed in the supply line 6 to control the flow of water supplied from the water source to the mixing section 5.

When the ozone water generator is forced to send air from the air pump 1 to the ozone generator 3 side, the ozone generator 3 changes oxygen in the air to ozone, and the changed ozone is partially decomposed into oxygen, but most of the mixing part It is a structure that pushes to (5) and mixes with water and discharges water supplied from a water source to ozone water.

The ozone water generating device sucks ozone into the shaft of the mixing unit 5 by using a negative pressure formed while passing water through the supply line 6 while the pressure is applied by the air pump, thereby mixing gas and liquid. Ozone water, that is, dissolved ozone water in which ozone is dissolved in water is discharged.

Typically, ozone water generators require various peripherals to maintain proper mixing of water and ozone. For example, a mixing unit that mixes ozone and water, an injector for generating negative pressure, and a gas-liquid separator that controls the amount of air introduced or separates gas and liquid, maintains a stable and constant mixing state of water and ozone. Auxiliaries for obtaining dissolved ozone water.

Problems in use arise.

In addition, the conventional ozone water generating device has a problem that frequently occurs clogging and pressure increase of the drainage side during system operation. This causes a problem in that a large amount of ozone gas flows out due to the backflow to the ozone generator and the incapacitation of the gas-liquid separator due to the phenomenon that the water flows back from the normal path.

The raw water supply path 20 is for supplying raw water to the reactor 100 by receiving raw water from a water source such as tap water, and the like, a raw water valve 21 and a pressure reducing valve 23 are installed on the raw water supply path 20. .

The raw water valve 21 is used to selectively turn on / off the supply of raw water through the raw water inlet 111 is used a solenoid valve and the like. The pressure reducing valve 23 is to maintain the water pressure of the raw water supplied through the raw water inlet 111 at a predetermined water pressure, and has a conventional pressure reducing valve structure.

The ozone supply path 30 is for supplying ozone generated by the ozone generator 31 to the first dissolution tank 110. The ozone supply path 30 is provided with a pump 33, a dryer 35, and a backflow on the ozone supply path 30. The prevention member 37 is installed. In addition, the ozone generator 31 and the pump 33 is connected and installed, the ozone amount adjusting device 200 for adjusting the ozone generation amount and the flow rate of the pump.

The ozone generator 31 is an apparatus for generating ozone gas using oxygen from the outside air dried by the dryer 35 using a flat ceramic electrode body, and has a structure of a conventional ozone generator. The dryer 35 removes moisture from external air introduced into the ozone generator 31 and supplies the dried air to the ozone generator 31, and has a conventional dryer structure.

The pump 33 has a function of sucking external air and a source for pressurizing and supplying the ozone gas via the ozone generator 31 to the first dissolution tank 110, that is, through the ozone inlet 113. As a supply of air, it is preferable to use a normal air pump, and it is made of the material which is corrosion-resistant to ozone gas. In addition, the position of the pump 33 can be changed before and after the dryer 35.

The ozone amount adjusting device 200 is to increase the flow rate of the pump by increasing the amount of ozone generated by the voltage change of the ozone generator 31 or by changing the output of the air pump 33, the configuration as shown in FIG. Is implemented as a circuit of. The ozone amount adjusting device 200 of the present invention is not limited to the circuit configuration shown in FIG. 6, and various modifications may be adopted to implement the same function.

Hereinafter, the ozone amount control circuit 200 according to the present invention will be described in detail with reference to FIG. 6.

The ozone amount adjusting circuit 200 of FIG. 6 is largely comprised of an ozone generator control unit 210 and a pump control unit 220. The ozone generator control unit 210 includes a selector switch (SW1) 212, a microcontroller (hereinafter referred to as MCU) 211, a photo coupler (213, 214) and a plurality of resistors (R7, R8, R9). . The selection switch 212 is disposed on the display unit (not shown) to cyclically generate a command signal of "strong to medium to weak to strong ..." according to the user's selection. The medicines are distinguished by voltage signals of different levels). This selection command is input to the input port PI1 of the MCU 211, and the MCU 211 generates a control signal based on this selection command, and the output ports PO1 and Output to PO2.

For example, when the selection command "strong" is input to the input port PI1, the MCU outputs a control signal of "PO1 = 5V, PO2 = 5V", and when the selection command "medium" is input, "PO1 = 5V, PO2" is input. The control signal of " = 0V " is outputted, and when the selection command " about " is inputted, the control signal of &quot; PO1 = 0V, PO2 = 5V &quot; This control signal is inputted to the light emitting diodes of the photo couplers 213 and 214, and then turns the photo transistors on or off.

As such, as the photo transistor is turned on or off, the circuit between the high voltage circuit and the resistor R8 or R9 is selectively shorted, and the parallel resistance of the composite resistor is changed. As such, as the synthesis resistance value connected to the high voltage circuit is changed, the magnitude of the voltage applied to the ozone generating electrode (not shown) is changed, and the amount of ozone is adjusted to strong, medium, or weak.

That is, when the control signal of the MCU is "P01 = 5V, PO2 = 5V", both the photo couplers 213 and 214 are turned on, and the parallel resistance value is represented by the combined resistance of R7, R8, and R9, and the control signal of the MCU is " When P01 = 5V, PO2 = 0V ", photo coupler 213 is turned on, 214 is turned off, and the parallel resistance value is represented by the combined resistance of R7 and R9, and MCU control signal is" P01 = 0V, PO2 = 5V ". In this case, the photo coupler 213 is turned off, and 214 is turned on so that the parallel resistance value is represented by the combined resistance of R7 and R8.

Therefore, the user can arbitrarily increase the ozone generation amount of the ozone generator 31 by appropriately selecting the selection switch 212.

In addition, the pump control unit 220 is a selection switch (SW2) 222 consisting of three fixed contacts and one moving contact, and the input port (PI2, PI3, PI4) of the fixed contact and MCU 211 Resistor elements R4, R5, and R6 connected between the transistors 221 are arranged between the output port PO3 / PWM of the MCU 211 and the air pump 33.

As the moving contact of the selection switch 222 is sequentially contacted with the three fixed contacts, input voltages of different levels corresponding to "strong, medium, and weak" are input ports PI2, PI3, PI4). The MCU 211 applies a pulse PWM corresponding to this input voltage to the air pump 33, and the rpm of the air pump 33 changes according to the duty rate of this output pulse. As such, by changing the rpm of the air pump, the flow rate of the air pump 33 can be increased to increase the ozone dissolution rate in the first dissolution tank 110.

That is, by switching the ozone generator control unit 210 and the selection switches 212 and 222 of the pump control unit 220 from the weak to the strong, the ozone generation amount and the inflow pressure thereof are increased to increase the first dissolution tank. The ozone dissolution rate at 110 can be easily increased.

The ozone destroyer 51 which introduces the ozone discharged from the second dissolution tank 120 to destroy ozone and the solenoid for selectively turning on / off the ozone discharge port 123 in the ozone discharge path 50. An exhaust valve 53 such as a valve is provided.

The ozone destroyer 51 includes an inlet for introducing the ozone gas, an air outlet connected to the exhaust valve 53, and a filter (not shown) filled in the destroyer body. The ozone destroyer 51 converts ozone into a gas that is harmless to the human body by reacting the ozone gas discharged through the ozone outlet 123 of the second dissolution tank 120 with an ozone depleting filter such as a catalyst and activated carbon. Let's do it.

FIG. 3 is a cross-sectional view of the first and second dissolution tank parts illustrated in FIG. 2.

2 and 3, the first dissolution tank 110 is provided with a raw water inlet 111 at one end thereof and an ozone inlet 113 and a surplus ozone gas outlet 117 at the other end thereof. The ozone water discharge port 115 is provided on a sidewall of a predetermined height of the first dissolution tank 110.

The first dissolution tank 110 has a structure of a substantially sealed container, the first connection pipe 119 is installed at the end of the ozone inlet 113 therein, the end of the first connection pipe 119 The first ozone diffuser 112 is installed. Thus, the first ozone diffuser 112 is located close to the raw water inlet 111. The first ozone diffuser 112 has a structure in which a plurality of through holes are formed therein, and when ozone passes through the through holes, the first ozone diffuser 112 can be more dissolved in raw water.

The first dissolution tank 110 is a space in which raw water and ozone are respectively mixed through the raw water inlet 111 and the ozone inlet 113 to generate ozone water, and the raw water inlet 111 and the ozone inlet 113 The position and size of) can be appropriately changed according to the capacity of ozone water to be generated.

When raw water is supplied to the inside of the first dissolution tank 110 through the raw water inlet 111, the raw water is filled to a certain level in the first dissolution tank 110, and at the same time ozone is ozone water inlet 125 and the first When supplied into the first dissolution tank 110 through the connecting pipe 119 and the first ozone diffuser 112, these liquids and gases are vertically diffused by buoyancy to be partially mixed to generate ozone water.

The ozone water is discharged to the second dissolution tank 120 through the ozone water discharge port 115, and the surplus ozone that is not dissolved in the raw water is the second dissolution tank 120 through the surplus ozone gas discharge port 113 and the bypass path 70. Is discharged.

The second dissolution tank 120 is provided with an ozone water outlet 121 at one end thereof, and a surplus ozone gas inlet 127 and an ozone outlet outlet 123 at the other end thereof. The ozone water inlet 125 is provided on the sidewall of the second dissolution tank 120 corresponding to the ozone water discharge port 115 of the first dissolution tank 110.

The second dissolution tank 120 has a structure of a substantially sealed container, a second connecting pipe 129 is installed at the end of the excess ozone gas inlet 127 therein, the second connecting pipe 129 At the end, a second ozone diffuser 122 is installed. Thus, the second ozone diffuser 122 is located close to the ozone water outlet 121. The liquid level detecting members 131 and 133 are installed in the second dissolution tank 120.

The second dissolution tank 120 has a function of secondary mixing of raw water and ozone in a process of receiving ozone water, raw water, and excess ozone gas supplied through the excess ozone gas inlet 127 and the ozone water inlet 125, and gas It is to completely separate (gas-liquid separation) of ozone and raw water and ozone water in a state. That is, when the ozone water of the first dissolution tank 110 flows into the second dissolution tank 120 through the connection path 60, the pressure inside the first dissolution tank 110 is increased. In addition, the ozone water is diffused through the ozone water inlet 125 of the second dissolution tank 120 and at the same time, the ozone in the gaseous state is vertically diffused by buoyancy by the second ozone diffuser 122, so that the ozone is secondary water or ozone water. Soluble in the ozone dissolution increases. On the other hand, ozone water dissolved in raw water and excess ozone in an undissolved gas state are gas-liquid separated in the second dissolution tank 120, and ozone dissolved ozone is drained through the ozone water outlet 121 and dissolved in raw water. Surplus ozone in the gaseous state that is not generated is discharged through the ozone outlet 123.

The liquid level sensing members 131 and 133 are for controlling the amount of raw water and / or ozone to the first dissolution tank 110 according to the level of ozone water accommodated in the second dissolution tank 120. The liquid level sensing member 160 includes a lower level sensor 131 and an upper level sensor 133. Of course, the installation position of the liquid level sensing member 160 can be appropriately adjusted.

Raw water inlet 111, ozone inlet 113, excess ozone gas outlet 117, ozone water outlet 115, surplus ozone gas inlet 127 of the second dissolution tank 120, ozone water The position and size of the inlet 125, the ozone water outlet 121, and the ozone outlet 123 can be changed as appropriate.

4 is a perspective view schematically showing an example of the concentration adjusting member of FIG. 2.

Referring to Figure 4, by adjusting the water intake amount of the ozone water discharged through the concentration adjustment member 140 ozone water outlet 121 to adjust the water intake amount installed in the ozone water outlet 121 to adjust the residence time in the second dissolution tank 120. A valve 142 is provided.

The water intake control valve 142 includes a valve body 140, a spool 143 located inside the valve body 141, a knob 145 connected to the spool 143, a valve body 141, and a knob 145. ) And a bracket 147 provided therebetween.

The valve body 141 is a hollow structure having a valve inlet 144 connected to the ozone water outlet 121 and a valve outlet 146 connected to the intake pipe 40.

The spool 143 communicates with the valve inlet 144 and the valve outlet 146 so that ozone water can be discharged toward the valve outlet 146. The communication portion has a spool inlet 149 connected to the valve inlet 144 and a spool outlet 148 formed in the longitudinal direction of the spool 143 and connecting the spool inlet 149 and the valve outlet 146. The spool 143 is rotatably installed in the valve body 141. One end of the spool 143 is formed with a first connection portion 151 connected to the knob 145.

The knob 145 adjusts the amount of ozone water flowing into the valve inlet 144 connected to the ozone water outlet 121 by rotating the spool 143 within the valve body 141 within a predetermined range (angle). The second connector 153 is coupled to the first connector 151.

That is, when the knob 145 is fully open, ozone water may be completely discharged from the ozone water outlet 121, but the valve inlet 144 and the spool inlet 149 communicate with each other by about 20 to 30% even when the knob is completely closed. Since the ozone water can be withdrawn through the water intake pipe 40. However, in this state, the residence time inside the second dissolution tank 120 increases, and the internal residence time of the second dissolution tank 120 increases by that amount. Then, the concentration of ozone water in the second dissolution tank 120 is increased, so that the concentration of ozone water withdrawn through the intake pipe 40 is increased.

Meanwhile, the above-described water intake control valve 142 may be a solenoid valve (not shown) installed between the ozone water outlet 121 and the water intake pipe 40 so as to be operated by the control unit. Of course, the solenoid valve may be employed a variety of solenoid valve.

Referring to the operation of the ozone sterilizing water production apparatus according to a preferred embodiment of the present invention configured as described above are as follows.

First, when the power switch (not shown) is pressed, the raw water valve 21 is operated to supply raw water to the first dissolution tank 110 through the raw water supply path 20. In this process, the water pressure of the raw water is maintained below a predetermined water pressure while passing through the pressure reducing valve 23.

Next, when raw water flows into the first dissolution tank 110 through the raw water inlet 111 connected to the raw water supply path 20, the raw water is connected to the ozone water discharge port 115 and the bypass path 60. It is supplied to the second dissolution tank 120 through 70. When the raw water is filled to some extent in the second dissolution tank 120 and the lower level sensor 133 detects this, the signal is sent to a control unit (not shown), and the control unit operates the pump 33. However, due to the circuit configuration of the device, the pump 33 may be set to operate simultaneously with the power switch.

Then, the pump 33 generates the sucked air and the air is introduced into the dryer 35, and the dryer 35 removes the moisture in the sucked air and converts it into dried air and then ozone generator 31. Will be sent to. The ozone generator 31 converts oxygen in the air into ozone and supplies it to the pump 33. The ozone gas discharged from the pump 33 passes through the backflow prevention member 37 and is supplied into the first dissolution tank 110 through the ozone inlet 113.

Next, ozone supplied through the ozone inlet 113 is introduced into the first dissolution tank 110 through the first connecting pipe 119 and the first ozone diffuser 112, and the introduced ozone gas is buoyant of raw water. Agitation is primarily performed inside the first dissolution tank 110 while contacting the raw water through vertical diffusion.

Subsequently, the surplus ozone gas in a gaseous state positioned above the first dissolution tank 110 due to the elevated pressure inside the first dissolution tank 110 is surplus ozone gas discharge port 117, the bypass path 70, and the surplus. After passing through the ozone gas inlet 127 and then supplied into the second dissolution tank 120 through the second connecting pipe 129 and the second diffuser 122, the raw water and ozone are agitated to dissolve ozone. Is converted to a number.

This process of moving excess ozone gas through the bypass path 70 is a process of dissolving ozone in raw water more and more, and at the same time a gas-liquid separation process that separates ozone water and excess ozone in an undissolved gas state. The dissolved ozone water and the raw water in the first dissolution tank 110 are supplied into the second dissolution tank 120 through the connection path 60.

On the other hand, when the state in which the raw water is filled in the second dissolution tank 120 is confirmed by the upper level sensor 131, the upper level sensor 131 transmits the information to the control unit and the control unit of the exhaust valve 53 Abort the operation. Then, the internal pressure of the second dissolution tank 120 is increased, and the ozone water received in the second dissolution tank 120 is rapidly discharged through the ozone water outlet 121 opened to the atmosphere through the intake pipe 40.

Then, when the level of the second dissolution tank 120 is gradually lowered and it is confirmed by the lower level sensor 133 that the liquid level in the second dissolution tank 120 is the lowest state, the control unit opens the exhaust valve 53. By lowering the internal pressure of the second dissolution tank 120 to raise the level of the second dissolution tank 120 to a higher level again.

If the water level of the second dissolution tank 120 is lowered below a lower level for a predetermined time, the ozone in the gas state may be discharged together with the ozone water through the ozone water outlet 121 so that the operation of the ozone generator 31 is stopped. To stop the release of gaseous ozone.

On the other hand, the excess ozone gas collected in the upper portion of the second dissolution tank 120 at the moment the exhaust valve 53 is opened is discharged through the ozone outlet 123 and the ozone discharge path 50, and such ozone gas is ozone. It flows into the destroyer 51.

The excess ozone gas introduced into the ozone destructor 51 is converted into carbon dioxide, which is harmless to the human body, and discharged into the atmosphere via the exhaust valve 53 through an air outlet.

On the other hand, when the concentration control member 140 is operated in the intake process through the intake pipe 40, it is possible to arbitrarily adjust the concentration of the ozone water to be withdrawn. That is, as shown in FIG. 4, when the knob 145 is completely opened, ozone water equal to the concentration of ozone water of the second dissolution tank 120 may be withdrawn through the intake pipe 40. However, as shown in FIG. 5, when the knob 145 is rotated, the spool 143 is rotated to displace the spool inlet 149 that is engaged with the valve inlet 144. Therefore, the amount of water discharged through the ozone water outlet 121 is reduced so that the contact time in the second dissolution tank 120 is eventually increased, and the contact time in the second dissolution tank 120 is increased and the water intake pipe is increased. Through 40, the concentration of ozone water to be withdrawn can be increased. In this embodiment, the valve inlet 144 and the spool inlet 149 are preferably set to overlap by about 20 to 30% even when the knob 145 is completely closed.

As described above, the ozone sterilizing water production apparatus capable of adjusting the ozone concentration according to the present invention has the following effects.

First, the ozone water production apparatus having a structure in which the first dissolution tank and the second dissolution tank are installed is removed from the conventional ozone dispersing system having a low ozone dissolution rate, and an ozone diffuser is installed at the inlet of the ozone to show the optimum ozone dissolution rate. In addition to vertical diffusion through the so-called sudden expansion tube, an optimum ozone dissolution rate can be obtained due to the additional stirring of ozone.

Second, since the excess ozone gas discharged from the reaction tank is removed by the ozone destroyer, problems such as indoor air pollution and inconvenience of the user due to the ozone gas can be solved.

Third, since the concentration of the dissolved ozone water in the second dissolution tank can be adjusted using the concentration adjusting member, it is possible to drink higher concentration ozone water.
