  Next, the ozonizer 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  The ozonizer 1 generates ozone (ozone gas) from a raw material gas [containing oxygen (for example, high-purity oxygen gas having an oxygen concentration of 99.9% or more)]. As shown in FIG. 1 or 2, the ozonizer 1 includes an outer electrode 2, an inner electrode 3, a dielectric 4, a power source (AC power source) 5, a discharge space 6, a space 7 in which no discharge occurs, Is provided.

  The outer electrode 2 and the inner electrode 3 of the ozonizer 1 are metal electrodes and are arranged so as to be spaced from each other. The outer electrode 2 of the ozonizer 1 is configured as a ground electrode, and the inner electrode 3 is configured as a high voltage electrode. The dielectric 4 of the ozonizer 1 is provided on the outer electrode 2. The dielectric 4 of the ozonizer 1 is disposed on the surface of the outer electrode 2 facing the inner electrode 3. The ozonizer 1 is configured such that a voltage (AC voltage) from the power source 5 is applied between the outer electrode 2 and the inner electrode 3 in the vicinity of the dielectric 4 (between the dielectric 4 and the inner electrode 3). It is configured to discharge into the space between the electrode 2 and the inner electrode 3. A space between the outer electrode 2 and the inner electrode 3 (between the dielectric 4 and the inner electrode 3) in the vicinity of the dielectric 4 of the ozonizer 1 is configured as a discharge space 6. The discharge space 6 of the ozonizer 1 is disposed in the vicinity of the dielectric 4.

  In the ozonizer 1 configured as described above, a source gas is supplied into the ozonizer 1, and the source gas supplied into the ozonizer 1 reaches the discharge space 6 and is applied with a voltage from the power source 5 to discharge. By being discharged in the space 6, oxygen atoms are dissociated from oxygen molecules in the source gas in the discharge space 6, and the dissociated oxygen atoms and oxygen molecules are combined to generate ozone (O3). The generated ozone is configured to flow out of the ozonizer 1. In this way, the ozonizer 1 is configured to generate ozone by generating a discharge by applying a voltage to the discharge space 6 between the outer electrode 2 and the inner electrode 3 while supplying the raw material gas. Is done. In this way, the ozonizer 1 is configured so that the source gas or ozone flows in the ozonizer 1.

  The space 7 where the discharge of the ozonizer 1 is not generated is arranged in the vicinity of the dielectric 4. The space 7 in which the discharge of the ozonizer 1 does not occur indicates a space 7 in the vicinity of the dielectric 4 in which no discharge occurs even when the discharge space 6 is discharged by applying a voltage from the power source 5. .

  The ozonizer 1 is configured such that no discharge is generated in the space 7 where no discharge occurs even when a voltage is applied while the source gas is supplied in the discharge space 6 to generate a discharge. The ozonizer 1 is configured so that a discharge space 6 and a space 7 in which no discharge occurs are continuous along the dielectric 4. The ozonizer 1 includes a discharge space 6 (a place where discharge is performed) and a space 7 where no discharge occurs along the dielectric 4. The ozonizer 1 is configured such that a space 7 in which no discharge occurs is disposed in the middle of the flow path of the source gas or ozone in the vicinity of the dielectric 4.

  Next, a more specific configuration of the ozonizer 1 will be described. The outer electrode 2 of the ozonizer 1 is formed in a cylindrical shape. The dielectric 4 of the ozonizer 1 is composed of a member made of a glass material, for example. The dielectric 4 of the ozonizer 1 is provided over the entire inner surface (inner peripheral surface) of the outer electrode 2. The inner electrode 3 of the ozonizer 1 is composed of a metal wire. The inner electrode 3 of the ozonizer 1 is disposed inside the outer electrode 2 (dielectric 4) so that the discharge space 6 is formed. The inner electrode 3 of the ozonizer 1 is arranged from one opening of the outer electrode 2 to the other opening. The inner electrode 3 of the ozonizer 1 is arranged along the axial direction of the outer electrode 2. The inner electrode 3 of the ozonizer 1 is disposed so as to extend from one opening of the outer electrode 2 to the other opening. In this way, the inner electrode 3 of the ozonizer 1 is arranged so that the electric field concentrates in the vicinity of the inner electrode 3. The outer electrode 2 (dielectric 4) of the ozonizer 1 is disposed outside the inner electrode 3 so that the discharge space 6 is formed.

  The white arrows in the figure indicate the flow direction of the source gas or ozone in the ozonizer 1 where the source gas is supplied into the ozonizer 1 and the ozone generated in the ozonizer 1 flows out of the ozonizer 1. The ozonizer 1 is configured so that the source gas or ozone flows along the axial direction of the outer electrode 2. The ozonizer 1 is configured such that a source gas is supplied into the ozonizer 1 from one opening in the outer electrode 2. The ozonizer 1 is configured to generate ozone in the ozonizer 1 by generating a discharge in the discharge space 6 in a state where the source gas is supplied into the ozonizer 1 and reaches the discharge space 6. The ozonizer 1 is configured such that ozone generated in the ozonizer 1 flows out from the other opening of the outer electrode 2. In the ozonizer 1, for example, a fan is provided in one opening or the other opening of the outer electrode 2, and when the fan is driven, source gas is supplied into the ozonizer 1, or ozone is supplied into the ozonizer 1. Configured to flow out of.

  As described above, in the ozonizer 1, the inner electrode 3 is made of a metal wire and is arranged so that the electric field concentrates in the vicinity of the inner electrode 3. That is, in the ozonizer 1, the discharge space 6 is not disposed on the entire inner side of the dielectric 4, and the electric field is not distributed on the entire inner side of the dielectric 4. Therefore, in the ozonizer 1, when the discharge space 6 is operated to generate a discharge to generate ozone, the discharge space 6 is compared with a structure in which the discharge space 6 is arranged entirely inside the dielectric 4. The electric field strength in the space 6 can be increased, and high concentration ozone can be efficiently generated.

  Further, in the ozonizer 1, even when the operation of generating ozone is performed, no discharge occurs in the space 7 where no discharge occurs, and therefore no temperature rise due to the occurrence of discharge occurs. For this reason, in the ozonizer 1, the temperature rise in the discharge space 6 when the operation of generating ozone is performed is suppressed by being affected by the temperature rise due to the occurrence of the discharge in the space 7 where no discharge occurs. Will be. Thus, in the ozonizer 1, compared with a configuration in which the discharge space 6 is arranged on the entire inside of the dielectric 4 (a configuration in which the space 7 in which no discharge is generated in the vicinity of the dielectric 4 is not provided). It is possible to suppress the temperature rise of the discharge space 6 when performing the operation of generating. Therefore, in the ozonizer 1, when the operation | movement which produces | generates ozone is performed, it can suppress that the produced | generated ozone is decomposed | disassembled with a heat | fever (reduction | reduction to oxygen). Therefore, according to the ozonizer 1, it is possible to efficiently generate ozone having a high concentration as compared with a configuration in which the discharge space 6 is arranged on the entire inside of the dielectric 4. Moreover, according to the ozonizer 1, since the temperature rise of the discharge space 6 when the operation | movement which produces | generates ozone is performed is suppressed, even when it installs in a high temperature environment (for example, 60 degreeC or more), it is a dielectric material. Compared with the configuration in which the discharge space 6 is arranged on the entire inner side of 4, ozone having a higher concentration can be efficiently generated.

  The ozonizer 1 has a plurality of inner electrodes 3 (metal wires) (two in this embodiment). The plurality of inner electrodes 3 of the ozonizer 1 are arranged at predetermined intervals so as not to disperse the electric field in the vicinity of the inner electrode 3. For this reason, in the ozonizer 1, when the operation | movement which generate | occur | produces discharge in the discharge space 6 and produces | generates ozone is performed, high concentration ozone can be produced | generated more efficiently.

  Further, in the ozonizer 1 configured as described above, the temperature rise of the discharge space 6 when the operation of generating ozone is performed as compared with the configuration in which the discharge space 6 is arranged on the entire inside of the dielectric 4. Can be more reliably suppressed. Therefore, in the ozonizer 1, when the operation | movement which produces | generates ozone is performed, it can suppress more reliably that produced | generated ozone is decomposed | disassembled with a heat | fever. Therefore, according to the ozonizer 1, it is possible to generate ozone with a higher concentration more efficiently than a configuration in which the discharge space 6 is arranged on the entire inside of the dielectric 4.

  The inner electrode 3 of the ozonizer 1 is arranged to be tensioned so as to be pulled from one opening side of the outer electrode 2 in the inner electrode 3 and the other opening side of the outer electrode 2 in the inner electrode 3. The As described above, in the ozonizer 1, the inner electrode 3 is disposed so as to be tensioned, so that the position of the inner electrode 3 in the outer electrode 2 is prevented from being shifted. Therefore, in the ozonizer 1, when the inner electrode 3 is disposed in the outer electrode 2, or when the inner electrode 3 is disposed in the outer electrode 2, for example, the inner electrode 3 is made of a metal wire, and the inner electrode 3 Compared to the structure in which the core 3 is wound around the core member, the distance between the inner electrodes 3 and 3 can be maintained at a desired distance, and the inner discharge space 6 and the space 7 in which no discharge occurs. Can be held in a desired size or in a desired position.

  The ozonizer 1 includes a core member 8. The core member 8 of the ozonizer 1 is a member formed in a cylindrical shape made of, for example, a glass material. The core member 8 of the ozonizer 1 is configured to have an outer diameter smaller than the inner diameter of the outer electrode 2 and the dielectric 4. The core member 8 of the ozonizer 1 is disposed inside the outer electrode 2 (dielectric 4) so that the axis of the ozonizer 1 coincides with the axis of the outer electrode 2. The core member 8 of the ozonizer 1 is disposed so that the inner electrode 3 is located on the outer side (outer peripheral surface side) of the core member 8.

  As described above, the ozonizer 1 is configured to include the core member 8 disposed inside the outer electrode 2. For this reason, in the ozonizer 1, the source gas supplied into the ozonizer 1 is circulated so as to be brought closer to the discharge space 6 by the core member 8. Therefore, according to the ozonizer 1, it is possible to efficiently generate ozone gas by causing a larger amount of source gas to reach the discharge space 6 than in the case where the inner electrode 3 does not have the core member 8.

  Further, the core member 8 of the ozonizer 1 is configured to have a diameter larger than ½ of the inner diameter of the outer electrode 2. Since it is configured in this way, according to the ozonizer 1, it is possible to reliably reach the large number of source gas discharge spaces 6 and efficiently generate ozone gas.
