Hereinafter, a preferred embodiment of the ozone generating device according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a module configured as an embodiment generates ozone as a discharge generated by supplying air and applying an active plasma high voltage. Here, the plasma high voltage refers to a high voltage in a state that is unstablely applied according to the embodiment.

First, air is supplied for ozone generation by the pump 12 through the dehumidification and cooling unit 10, and at this time, the dehumidification and cooling unit 10 employs a filter for dehumidification and sterilization, and a thermocouple is used for cooling. Can be employed.

The dehumidification and cooling unit 10 can obtain a power saving effect, and supplies air to the pump 12 in a dry state by using a low-cost dehumidification filter.

In addition, the air pumped at high speed by the pump 12 flows into the ozone generator 14, and the oxygen contained in the air in the ozone generator 14 applies energy by a discharge phenomenon caused by an active plasma high voltage. Large amounts are converted to ozone.

Air flows to the dehumidification and cooling unit 10, the pump 12, and the ozone generator 14 at high speed by the supply pipe 16, and the ozone generator 14 may be provided with a plurality of quartz glass tubes. have.

In an embodiment, the ozone generating unit 14 has an upper and lower heat dissipation block 20 and 22 assembled therein, and has a semicircular longitudinal groove 24 formed on a surface corresponding to each other of the upper and lower heat dissipation blocks 20 and 22. The quartz glass tube 26 is fitted.

In addition, the upper and lower heat dissipation blocks 20 and 22 having a symmetrical structure are formed with heat dissipation fins 28 in a vertical direction symmetrical with each other.

The groove 30 formed at the center of the lower heat dissipation block 22 is for fitting the fastener 34 coupled to the base 32, and the fastener 34 having the end bent in one direction is coupled to the base 32. The ends are respectively spread over both sides of the grooves of the lower heat dissipation block 22 to fix the lower heat dissipation block 22, and the quartz glass tube 26 is inserted into the fixed upper part, and the upper heat dissipation block 20 is disposed thereon. ) Is positioned, and the upper and lower heat dissipation blocks 20 and 22 are joined by screws 36.

Then, an aluminum film 27 is wrapped on the outer wall of the quartz glass tube 26, and a platinum film 29 is additionally wrapped on the outside thereof. These films are for forming cold electrodes. The hot electrode 31 is formed inside the quartz glass tube 26. The hot electrode 31 may be made of platinum or stainless 316 material.

In addition, the reason why the electrode is made of platinum is generally used to prevent blackening from occurring in the quartz glass tube 26 when the material constituting the electrode is used. When the platinum film 29 is used as an electrode, the blackening phenomenon described above is suppressed.

The high voltage generated by the controller 40 is applied to the hot electrode and the cold electrode, and the high voltage may be actively applied by the controller having the configuration as shown in FIG. 3 or 4 according to an embodiment of the present invention. have.

Therefore, the high voltage applied in the active state at this time is applied to the electrode while having the shape of a pulse. At this time, the high voltage has a pulse current in which the high frequency and the low frequency are repeated by the reset action of the oscillator, and accordingly, the oxygen contained in the air supplied at high speed obtains energy by the discharge caused by the high voltage having the variable frequency. Generated by ozone. At this time, when the high frequency is applied inside the quartz glass tube, the local discharge is generated, and as the frequency of the high voltage becomes low, the discharge region is generated in such a way as to expand. When reset, the phenomenon of discharging all over the quartz glass tube is returned to local discharge by application of a high frequency high voltage, and the above-described discharge phenomenon is repeated.

This discharge phenomenon does not generate heat that can be excessively acting on the quartz glass tube, and the weakly generated heat is first filtered and cooled in the dehumidification and cooling unit, and is cooled by the air supplied at a high speed. It can be cooled by the heat circulation action through.

Ozone generally has a characteristic that the amount of generation is reduced in the atmospheric state of 45 ℃ or more, but the embodiment according to the present invention can be maintained because the temperature environment of the below state by the action of the air and the heat radiation block supplied at high speed ozone is A large amount can be produced in the quartz glass tube 26.

In addition, the size of the quartz glass tube 26 may be improved by solving the overheating problem, thereby generating ozone at a large capacity. In addition, the heat dissipation block may be separated into upper and lower parts, so that if the quartz glass tube 26 is damaged, the heat dissipation block may be easily replaced by disassembling the heat dissipation block, thereby providing an advantage in maintenance and management.

The configuration of the control unit 40 applying the high pulse voltage as described above will be described with reference to FIGS. 3 and 4.

First, the controller 40 configured as shown in FIG. 3 is supplied with the current supplied from the commercial power supply 100 to the rectifier circuits 106 and 108 through the lightning protection circuit 102 and the EMI filter 104, respectively, and rectified. The current output from the circuit 108 is mixed with the output of the drive transformer 112 while being converted into direct current in the mixing unit 110 and applied to the primary side (not shown) of the flyback transformer 114, and the flyback transformer 114 induces and generates a high pressure of several K volts on the secondary side (not shown) and applies it to the electrodes of the quartz glass tube 26.

Here, the lightning protection circuit 102 blocks the overcurrent caused by the lightning, and the EMI filter 104 filters the noise component mixed through the power supply line.

The output of the rectifier circuit 106 is output to the high voltage breaking circuit 116 and the oscillator 118 via the DC converter 107.

The DC converter 107 converts the output of the rectifier circuit 106 to have a DC component, and outputs the DC converter. The high-voltage breaker circuit 116 indicates that the quartz glass tube 26 is damaged when the voltage caused by the input current is high. To prevent this, a control signal for adjusting the output of the flyback transformer 114 is output.

In addition, the power display unit 120 and the frequency control unit 122 are connected to the oscillator 118, and the power display unit 120 is turned on when the normal power is supplied and is turned off when abnormal power is supplied to check the current operation state. To help. In addition, the frequency controller 122 may be configured using a variable resistor, and adjusts the output frequency of the oscillator 118 from several tens of KHz to several hundred KHz.

The oscillator 118 includes a reset unit 119. The reset unit 119 charges the output of the oscillator 118 and applies a reset signal to the oscillator 118 when the charge level is higher than or equal to a predetermined level. Accordingly, the output of the oscillator 118 is actively variable at high and low frequencies.

The oscillator 118 outputs a pulse having a variable frequency according to the current supply from the rectifier circuit 106 in a PWM manner by the resistance value set in the frequency controller 122 and the reset signal of the reset unit 119, and a driving transformer ( 112 outputs an induced voltage to the FET output unit 113 by a pulse input to the primary side, and the FET output unit 113 is configured in parallel therewith and is positive and positive by a pair of FETs having a common ground. Each has a negative output. In the FET output unit 113, a line for grounding is wired to a line for grounding of the rectifier circuit 108 and the mixing unit 110.

As a result, FIG. 3 shows the output of the rectifying circuit 108 in the driving transformer 112 so that the positive and negative outputs from the FET output 113 are mixed in the mixing unit 110 and fly. As it is applied to the primary side of the back transformer 114, the flyback transformer outputs a high voltage of the pulse stream having non-sinusoidal frequency characteristics.

As the high voltage of the pulse generated as described above is applied to the quartz glass tube, an active plasma discharge is generated inside the quartz glass tube by a plasma high voltage whose frequency is variable. Accordingly, the discharge region is changed and ozone is not generated. Is generated. Therefore, it is not affected by heat and a large amount of ozone is released without dissipation.

Meanwhile, the controller 40 may be configured as shown in FIG. 4. The current supplied from the commercial power supply 200 is supplied to the rectifier circuits 206 and 208 through the lightning protection circuit 202 and the EMI filter 204, respectively, and the current output from the rectifier circuit 208 is mixed with the mixer 210. ) Is mixed with the output through the FET output unit 213 of the drive transformer 212 is applied to the primary side of the flyback transformer 214, the flyback transformer 204 is applied to a high voltage of several KV level It is produced and applied to the electrodes of the quartz glass tube 26.

Here, the lightning protection circuit 202 prevents the overcurrent caused by the lightning, and the EMI filter 204 filters the noise component mixed through the power supply line.

The output of the rectifier circuit 206 supplies a current to the DC converter 207, and the DC converter 207 converts the output of the rectifier circuit 206 to have a DC component.

That is, the DC converter 207 supplies current to the PWM oscillator 216, the low frequency oscillator 218, and the high frequency oscillator 220, and the current supply of the dual high frequency oscillator 220 is output from the low frequency oscillator 218. It is configured to be made through the switch 222 is switched by the control signal.

The power display 224 and the frequency controller 226 are connected to the PWM oscillator 216, and the frequency controller 228 is connected to the low frequency oscillator 218. The power display unit 224 is turned on when the normal power supply is made and turned off when the abnormal power is supplied to check the current operation state.

In addition, the frequency controllers 226 and 228 may be configured using variable resistors, and the frequency controller 226 adjusts the frequency of the output signal of the PWM oscillator 216 from several tens of KHz to several hundred KHz, and the frequency controller 228. ) Adjusts the output of the low frequency oscillator 218. In this case, the output of the low frequency oscillator 218 should be adjusted in consideration of the time for adjusting the output of the high frequency oscillator 220.

The output of the PWM oscillator 216 and the output of the high frequency oscillator 220 are applied to the switch 230, and the output of the PWM oscillator 216 or the output of the high frequency oscillator 220 according to the internal terminal connection state of the switch 230. This is optionally applied to drive transformer 212.

The driving transformer 212 has an induction output by a pulse input to the primary side, and the induction output is output at high voltages of positive (+) and negative (−) components from the FET output unit 213.

As a result, FIG. 4 shows that the output of the drive transformer 212 driven by the PWM oscillator 216 or the high frequency oscillator 220 is output to the output output from the rectifier circuit 208 through the FET output unit 213. As a result of mixing in the mixing unit 210 and being applied to the primary side of the flyback transformer 214, the flyback transformer 214 has a non-sinusoidal frequency characteristic by a PWM method or a non-sinusoidal frequency characteristic by a high frequency characteristic. Output high voltage.

Meanwhile, if the connection state of the switch 230 is set to apply the output of the PWM oscillator 216 to the drive transformer 212 in this process, as shown in FIG. 3, the drive transformer driven by the pulse by the PWM method ( The induction output of 212 is mixed in the mixing section 210 at high voltage through the FET output section 213.

Alternatively, when the connection state of the switch 230 is set to apply the output of the high frequency oscillator 220 to the driving transformer 212, the low frequency oscillator 218 switches a control signal of a high or low level at a predetermined frequency to the switch 222. In response thereto, the high frequency oscillator 220 selectively outputs a high frequency pulse to the driving transformer 212 through the switch 230 according to the turn on / off state of the switch 222. Therefore, the mixing unit 210 applies a signal of the sinusoidal output and the non-sinusoidal output to the flyback transformer 214, and the flyback transformer 214 induces an active plasma high voltage output accordingly.

That is, as the pulsed plasma high voltage is applied to the quartz glass tube, an active plasma discharge is generated inside the quartz glass tube by a plasma high voltage whose frequency is variable. Accordingly, the discharge region is changed and ozone is generated without overheating. . Therefore, it is not affected by heat and a large amount of ozone is released without dissipation.

As a result, an active plasma high voltage is applied to the electrodes of the quartz glass tube 26 by the action of the controller 40 as in the first and second embodiments of FIGS. 3 and 4, and the discharge inside the quartz glass tube 26 is The activated state in which the region is expanded and contracted is repeated, and the oxygen contained in the air dehumidified and cooled in the dehumidification and cooling unit 10 receives energy from an active discharge generated by the plasma high voltage, and thus, It is changed to ozone.

At this time, the temperature environment of the quartz glass tube 26 does not cause a high temperature while the discharge state is variable, and maintains a low temperature by the cooled air, and the heat generated is discharged by the heat radiation block to effectively maintain the low temperature. Therefore, ozone generated at low temperature is discharged largely without change.

Therefore, according to the present invention has a structure that generates ozone by using an active high voltage, by implementing a cooled air and heat dissipation mechanism to prevent overheating, there is an effect that a large amount of ozone can be vividly supplied.

In addition, there is an advantage that the maintenance of the ozone generating device is easy with the improvement of the heat radiation block.
