Description

Technical Field

[0001] This disclosure relates to an ozone generating apparatus including an ozone generator that performs ozone generation treatment from a feed gas to a discharge space to generate ozone gas, and a method for installing internal components for object transfer in the ozone generating apparatus. Background Technology

[0002] As an example of an ozone generator, there is an ozone generator that performs ozone generation treatment by generating ozone gas from raw material gas (oxygen) supplied to the discharge space to generate ozone gas by generating discharge space dielectric barrier discharge.

[0003] Such existing ozone generating devices have a transfer component for transferring the transfer object used in the ozone generator. The transfer object can be, for example, ozone gas, oxygen, or other raw material gases; the transfer component can be an ozone gas passage for ozone gas transfer or a raw material gas passage for raw material gas transfer.

[0004] Furthermore, conventional ozone generating devices include an internal component for transferring ozone gas or other transferable materials to or from the outside. This internal component is connected to the transfer component in a manner that allows the transferable material to be transferred. For example, when the transferable material is ozone gas, the internal component is connected to the ozone gas passage in a manner that allows ozone gas to be transferred.

[0005] Figure 14 This is a schematic representation of the planar structure of the existing object transfer structure 60. Figure 15 This is an explanatory diagram schematically representing the cross-sectional structure of an existing object transfer structure 60.

[0006] As shown in these figures, the existing object transfer structure 60 includes, as its main structural elements, an outer frame component 61 having an opening 61b that is circular when viewed from above; and an object transfer inner component 62 disposed within the opening 61b, which is circular when viewed from above.

[0007] The outer frame component 61 includes an alloy outer perimeter 61a and an opening 61b that penetrates the central region of the alloy outer perimeter 61a as its main structural elements. The outer frame component 61 achieves weight reduction by using a relatively lightweight and high-strength material such as aluminum alloy as the structural material for the alloy outer perimeter 61a.

[0008] The main structural elements of the internal component 62 for transferring objects include an alloy outer perimeter 62a and a through flow path 62b that penetrates the central region of the alloy outer perimeter 62a. The through flow path 62b is circular when viewed from above to facilitate the transfer (flow) of the objects. As the structural material of the alloy outer perimeter 62a, a corrosion-resistant alloy material, such as stainless steel, is used, which has the resistance to corrosion when the objects being transferred flow through.

[0009] Thus, since it is necessary to change the structural material between the outer frame component 61 (alloy outer periphery 61a) and the object transfer inner component 62 (alloy outer periphery 62a), the object transfer structure 60 requires two components (outer frame component 61 + object transfer inner component 62).

[0010] In order to arrange the object transfer internal component 62 inside the opening 61b, the component diameter d62 of the object transfer internal component 62 is set to a length approximately the same as the opening diameter d61, so as to smoothly connect with the inner circumferential surface of the opening 61b (opening diameter d61).

[0011] The alloy outer periphery 61a, which is made of aluminum alloy, and the alloy outer periphery 62a, which is made of stainless steel, cannot be directly joined.

[0012] Therefore, in the conventional object transfer structure 60, in order to ensure the tight fit between the outer frame component 61 and the object transfer internal component 62, the O-ring 66, as a sealing component, becomes an essential structural element.

[0013] Specifically, a sealing groove 62c, which appears circular when viewed from above, is provided in the central region of the outer periphery of the alloy outer peripheral portion 62a. Furthermore, by providing a sealing element, namely an O-ring 66, which also appears circular when viewed from above, within the sealing groove 62c, the airtightness between the inner peripheral surface of the opening 61b of the outer frame member 61 and the outer peripheral surface of the object-transfer internal member 62 (alloy outer peripheral portion 62a) is improved. This is because an O-ring 66, serving as a sealing element, is sandwiched between the inner peripheral surface of the opening 61b of the outer frame member 61 and the outer peripheral surface of the object-transfer internal member 62.

[0014] Existing technical documents Patent documents Patent Document 1: Japanese Patent No. 3607890 Summary of the Invention

[0015] The problem that the invention aims to solve However, since O-ring 66 generally has the characteristic of deteriorating over time due to changes in hardness or corrosion, it is necessary to replace O-ring 66 during the use of the ozone generating device with object transfer structure 60.

[0016] Thus, existing ozone generating devices with object transfer structure 60 require replacement of the O-ring 66, which serves as a sealing component. As a result, there are problems such as reduced efficiency of the ozone generating device and increased environmental impact due to the disposal of the used O-ring 66.

[0017] Furthermore, removing the O-ring 66 during replacement is difficult, and there is a risk of performance degradation of the object transfer structure 60 due to damage to the outer frame component 61 and the object transfer internal component 62. Specifically, there is a risk of performance degradation due to damage to the inner circumferential surface of the alloy outer peripheral portion 61a (inner circumferential surface of the opening 61b) or the outer circumferential surface of the alloy outer peripheral portion 62a, which is the mating part between the outer frame component 61 and the object transfer internal component 62.

[0018] Thus, existing ozone generating devices with object transfer structure 60 suffer from reduced efficiency and increased environmental impact.

[0019] Furthermore, since the sealing components such as the O-ring 66 used in the existing object transfer structure 60 have the characteristic of deterioration over the years, there is a problem that conventional ozone generating devices with object transfer structures 60 cannot achieve a long service life.

[0020] The purpose of this disclosure is to address the aforementioned problems by providing an ozone generating device that, in a structure having internal components for object delivery, can reduce environmental impact and extend lifespan without compromising efficiency.

[0021] Methods for solving problems The ozone generating apparatus disclosed herein comprises: an ozone generator that generates a dielectric barrier discharge in a discharge space and performs an ozone generation process from a raw material gas supplied to the discharge space to generate ozone gas; an ozone gas passage for the flow of the ozone gas generated in the discharge space; a generator housing member that houses the ozone generator and the ozone gas passage within the housing space; and an object transfer internal member installed in a component mounting area of ​​the generator housing member, the object transfer internal member being connected to the transfer member in a manner that allows the ozone generator to transfer an object, the transfer member being a structure or space for transferring the object, the object including the ozone gas, and the transfer member containing... The device includes the ozone gas passage, the component mounting area has an opening, the object transfer internal component is disposed within the opening, the opening is circular in diameter when viewed from above, and the object transfer internal component is circular in diameter when viewed from above. The object transfer internal component has the following diameter variation characteristics: below a specified cooling temperature, the component diameter is smaller than the opening diameter; in a non-cooling temperature zone above the specified cooling temperature but above 0°C, the component diameter is larger than the opening diameter; in the non-cooling temperature zone, at the boundary between the outer peripheral surface of the object transfer internal component and the inner peripheral surface of the opening, the object transfer internal component and the opening are in close contact without any other components separating them.

[0022] Invention Effects In the generator housing component of the ozone generating device disclosed herein, the object transfer internal component is installed in a tightly fitted state with high airtightness, where the object transfer internal component is tightly fitted inside the opening without being separated from other components when the temperature is not cooled.

[0023] Since the object transfer internal component has the aforementioned diameter variation property, after the object transfer internal component, which is set to a state below a specified cooling temperature, is placed in the opening of the component mounting area, the temperature of the object transfer internal component is set to a non-cooling temperature zone. As a result, the object transfer internal component can be mounted in the component mounting area of ​​the generator housing component in the aforementioned close-fitting mounting state.

[0024] As a result, in the ozone generating device disclosed herein, the internal components for object transfer do not have any parts that need to be replaced or processed during use, thus reliably avoiding a decrease in the efficiency of the ozone generating device.

[0025] Furthermore, in the ozone generating device disclosed herein, the internal components for object transfer do not have components that become replaceable during use. Therefore, there is no possibility of damage to the internal components for object transfer or the component installation area due to component replacement, thus enabling the ozone generating device to have a long service life.

[0026] Furthermore, the object transfer internal components of the ozone generating device disclosed herein do not have any components that become waste objects during use, thus enabling the reduction of environmental impact.

[0027] The purpose, features, aspects, and advantages of this disclosure become clearer from the following detailed description and accompanying drawings. Attached Figure Description

[0043] <Implementation Method 1> Figure 1 This is an explanatory diagram schematically showing the cross-sectional structure of the object transfer structure 30 provided in the ozone generating apparatus 100 described later in Embodiment 1 of this disclosure. Figure 2 It is a schematic representation Figure 1 An explanatory diagram of the cross-sectional structure of the outer frame component 31 in the object transfer structure 30. Figure 3 This is an explanatory diagram schematically showing the cross-sectional structure of the internal component 32 for object transfer in the object transfer structure 30.

[0044] As shown in these figures, the main structural elements of the object transfer structure 30 in Embodiment 1 include: an outer frame member 31 having an opening 31b that is circular when viewed from above; and an object transfer inner member 32 disposed within the opening 31b and which is circular when viewed from above.

[0045] The object transfer internal component 32 is a component that is connected to the transfer component in a manner that allows the transfer of the object to be transferred, as described later in the ozone generator 101. The "transfer component" is a structure or space used to transfer the object.

[0046] The outer frame component 31 includes an alloy outer perimeter 31a and an opening 31b that extends through the central region of the alloy outer perimeter 31a as its main structural elements. The outer frame component 31 achieves weight reduction by using a relatively lightweight and high-strength material such as aluminum alloy as the structural material for the alloy outer perimeter 31a.

[0047] In the object transfer internal component 32, the main structural elements include an alloy outer peripheral portion 32a and a through-flow path 32b that penetrates the central region of the alloy outer peripheral portion 32a. The through-flow path 32b is circular with a through diameter d3 in a top view to allow the transfer object to be transferred (flow through). As the structural material of the alloy outer peripheral portion 32a, a corrosion-resistant alloy material such as stainless steel, which has the resistance not to corrode when the transfer object flows through, is used for example.

[0048] The opening 31b of the outer frame component 31 is circular with an opening diameter d1 in a top view, and the object transfer internal component 32 is circular with a component diameter d2 in a top view.

[0049] Hereinafter, in this specification, "transfer" is used as a concept including the flow of gases such as raw material gases, the flow of liquids such as refrigerants containing cooling water, and the transfer of electrical signals such as electricity (voltage).

[0050] Thus, since it is necessary to change the structural material between the outer frame component 31 (alloy outer peripheral portion 31a) and the object transfer internal component 32 (alloy outer peripheral portion 32a), the object transfer structure 30 requires two components (outer frame component 31 + object transfer internal component 32).

[0051] As Figure 1 shown, in the object transfer structure 30, the outer frame component 31 uses the opening 31b and the peripheral region of the opening 31b as a component mounting area, and mounts the object transfer internal component 32 in the component mounting area such that the object transfer internal component 32 is disposed within the opening 31b.

[0052] The object transfer internal component 32 in the object transfer structure 30 of Embodiment 1 has the following diameter variation characteristics.

[0053] Diameter variation characteristics... When the temperature is below a specified cooling temperature, i.e., cooling temperature T1, the component diameter d2 of the object transfer internal component 32 is smaller than the opening diameter d1 of the opening 31b. When the temperature is in a non-cooling temperature range TH that is higher than the cooling temperature T1 and 0°C or higher, the component diameter d2 becomes equal to or larger than the opening diameter d1.

[0054] Here, if the component diameter d2 at a temperature below the cooling temperature T1 is defined as the component diameter d22 during cooling, and the component diameter d2 in the non-cooling temperature range TH is defined as the component diameter d21 during non-cooling, then between the component diameter d2 and the opening diameter d1 of the opening 31b, {d21 < d1 ≤ d22} holds.

[0055] Thus, the object transfer structure 30 of Embodiment 1 has the following diameter variation properties: when the cooling temperature T1 is below, the component diameter d2 (= component diameter d22 when cooled) is less than the opening diameter d1; when the non-cooling temperature zone TH is below, the component diameter d2 (= component diameter d21 when not cooled) is greater than or equal to the opening diameter d1.

[0056] Because the object transfer internal component 32 has the aforementioned diameter variation characteristics, when the object transfer structure 30 is in the non-cooled temperature zone TH, the boundary surface 33 between the outer peripheral surface of the object transfer internal component 32 and the inner peripheral surface of the opening 31b is in a tightly fitted state where the object transfer internal component 32 and the outer frame component 31 are strongly and tightly attached.

[0057] The object transfer internal component 32 can be installed into the component mounting area of ​​the outer frame component 31 as follows. After placing the object transfer internal component 32, which is set to a state below the cooling temperature T1, into the opening 31b of the component mounting area, the temperature of the object transfer internal component 32 is set to the non-cooling temperature range TH. Furthermore, the installation method of the object transfer internal component 32 will be described in detail in Embodiment 2 described later.

[0058] In this way, in the object transfer structure 30, the object transfer internal component 32 is installed in the opening 31b in a close-fitting state without being separated from other components, including sealing components such as O-rings.

[0059] Figure 4 It is a schematic representation of having Figures 1-3 An explanatory diagram of the structure of the ozone generating device 100 according to Embodiment 1 of the object transfer structure shown.

[0060] The ozone generating device 100 functions as a flat-panel stacked ozone generating device and is a generator housing component having a housing space S100 for housing the ozone generator 101, and has a combination of a base 24 and a generator cover 110.

[0061] That is, the generator housing component includes a base 24 and a generator cover 110 disposed on the surface of the base 24, and a housing space S100 is formed on the surface of the base 24.

[0062] An ozone generator 101 is housed within the containment space S100. The ozone generator 101 causes a dielectric barrier discharge in the discharge space 6, performing an ozone generation process that generates ozone gas G2 from the raw material gas G1 such as oxygen supplied to the discharge space 6.

[0063] Furthermore, the ozone generating device 100 includes an ozone transformer 200 and a high-frequency inverter 300 as a power supply unit for supplying power to the ozone generator 101.

[0064] The high-frequency inverter 300 converts the power input from the power input 404 into the necessary frequency and outputs it to the inverter output cable 403. The ozone transformer 200 boosts this power to a specified voltage, supplying the ozone generator 100 with the high-voltage ozone generation power required for ozone generation.

[0065] The ozone-generating power (voltage) supplied from the ozone transformer 200 is delivered from the high-voltage cable 401, which serves as the power supply line, through the high-voltage bushing 120 (including the relay terminal 121), and the power supply terminal 4 within the housing space S100 to the high-voltage electrode 3 of the ozone generator 100. On the other hand, low voltage is supplied from the low-voltage cable 402 to the low-voltage electrode 7 via the base 24.

[0066] The ozone generator 100 includes multiple electrode modules 102, each containing a high-voltage electrode 3 and a low-voltage electrode 7 as main structural elements. A predetermined number of electrode modules 102 are stacked on the base 24 in the order of "N-1", "N-2", "N-3", ... "N-7" and "N-8" along the direction of arrow Z in the figure to form the ozone generator 101.

[0067] The ozone generator 101 is covered by a generator cover 110. A raw material gas inlet 130 is provided on the side 110s of the generator cover 110 for supplying raw material gas G1 containing trace amounts of nitrogen, carbon dioxide, etc. The supplied raw material gas G1 fills the containment space S100 and enters the discharge space 6.

[0068] On the other hand, the base 24 is provided with an ozone gas outlet 11 for discharging ozone gas G2 generated in the discharge space 6 from the ozone generator 100 to the outside, and a refrigerant inlet / outlet 12 for cooling water and other refrigerants to enter and exit the electrode module 102.

[0069] Figure 5 This is an explanatory diagram schematically showing the structure of the region of interest R1 of the ozone generator 101. As shown in the diagram, a plate-shaped high-voltage electrode 3 is disposed opposite to a plate-shaped low-voltage electrode 7, and a plate-shaped dielectric 5 is disposed between the low-voltage electrode 7 and the high-voltage electrode 3. Furthermore, a discharge space 6 is formed between the low-voltage electrode 7 and the dielectric 5 through a spacer (not shown) separated by the dielectric 5.

[0070] from Figure 4 The ozone transformer 200 shown supplies ozone-generating power to the high-voltage electrode 3 via the high-voltage bushing 120 (relay terminal 121) and the power supply terminal 4. The high-voltage electrode 3 is made of metals such as stainless steel and aluminum. The main surface of the dielectric 5 is in close contact with the high-voltage electrode 3. The dielectric 5 is made of materials such as ceramic, glass, and silicon.

[0071] In the ozone generating device 100, which is the basic structure of Embodiment 1, the discharge space 6 is formed into a circular plate shape when viewed from above, and the raw material gas G1, which fills the containment space S100, is injected from the entire periphery of the discharge space 6 toward the center. That is, in the ozone generating device 100, the containment space S100 functions as a transfer component for transferring (supplying) the raw material gas G1 to the discharge space 6 of the ozone generator 101.

[0072] By applying an alternating high voltage from the electrode supply section, which includes the ozone transformer 200 and the high-frequency inverter 300, to the high-voltage electrode 3 and the low-voltage electrode 7, a dielectric barrier discharge is generated in the discharge space 6. Therefore, the ozone generator 101 can perform an ozone generation process that converts a raw material gas G1, such as oxygen, flowing in the discharge space 6 into ozone gas G2. The ozone gas G2 generated by the ozone generation process is guided from the center of the low-voltage electrode 7 through an ozone gas passage 8 provided within the low-voltage electrode 7 to the ozone gas outlet 11 provided on the base 24.

[0073] The low-pressure electrode 7 is a thin, conductive rigid body formed by joining two conductive plates, such as stainless steel plates, with an ozone gas passage 8 formed between the plates. In addition to the ozone gas passage 8, the low-pressure electrode 7 also includes a refrigerant passage 9 to improve ozone generation efficiency. Furthermore, by allowing a refrigerant such as cooling water to flow through this refrigerant passage 9, the gas temperature within the discharge space 6 is reduced.

[0074] On the other hand, in order to cool the high-voltage electrode 3, a water-cooled electrode cooling plate 1 is disposed on the high-voltage electrode 3, separated by an insulating plate 2 with excellent thermal conductivity. The electrode cooling plate 1 is a thin plate-shaped rigid body formed by joining two steel plates made of stainless steel or the like, with a refrigerant passage 9 formed between the plates. That is, a refrigerant passage 9 is also provided inside the electrode cooling plate 1, and a refrigerant such as cooling water flows in the refrigerant passage 9.

[0075] The ozone gas passage 8 formed in the low-pressure electrode 7 is connected to the ozone gas outlet 11 provided on the base 24. On the other hand, the refrigerant passage 9 formed in the electrode cooling plate 1 and the low-pressure electrode 7 is connected to the refrigerant inlet / outlet 12 provided on the base 24.

[0076] Ozone gas passage 8 is a passage for the flow of ozone gas G2 generated in discharge space 6, and refrigerant passage 9 is a passage for supplying refrigerant to ozone generator 101.

[0077] The electrode module 102, which includes a low-voltage electrode 7, a high-voltage electrode 3, a dielectric 5, a spacer (not shown), an insulating plate 2, and an electrode cooling plate 1, is fixed in a state where the electrode pressure plate 22 is fastened to the base 24 by fastening bolts 21 that pass through each structural element.

[0078] Figure 6 It means Figure 4 A detailed diagram illustrating the area of ​​interest R2 of the base 24. As shown in the diagram, the internal component 51 for ozone gas is positioned in relation to... Figures 1-3 The object conveying internal component 32 shown has the same structure. Here, the base 24 corresponds to the outer frame component 31, and the opening 31b in the base 24 for mounting the internal component 51 for ozone gas and its surrounding area become the component mounting area.

[0079] That is, an ozone gas internal component 51, which serves as an object transfer internal component 32, is installed within the base 24 (opening 31b) that forms the outer frame component 31. Therefore, the through flow path 32b of the object transfer internal component 32 becomes the ozone gas outlet 11 of the ozone gas internal component 51. In the ozone gas internal component 51, the object to be transferred becomes ozone gas G2, and the transfer component becomes the ozone gas passage 8. Furthermore, Figure 6 The opening 31b shown becomes a groove structure that is closed from above.

[0080] The internal component 51 for ozone gas is connected to the ozone gas passage 8 in a manner that allows ozone gas G2 to flow through the through-flow path 32b of the internal component 32 via an object. Furthermore, the connection between the internal component 51 and the ozone gas passage 8 is performed using existing connection methods (joining methods) such as insert welding or butt welding. Figure 6 In the configuration shown, the ozone gas passage 8 and the outer frame component 61 are joined in such a way that the front end of the ozone gas passage 8 enters the ozone gas outlet 11.

[0081] A refrigerant internal component 52, which serves as an object transfer internal component 32, is installed within the base 24 (opening 31b) of the outer frame component 31. Therefore, the through flow path 32b of the object transfer internal component 32 becomes the refrigerant inlet / outlet 12 of the refrigerant internal component 52. In the refrigerant internal component 52, the object transferred is a refrigerant CM such as cooling water, and the transfer component is the refrigerant passage 9.

[0082] The refrigerant internal component 52 is connected to the refrigerant passage 9 in such a way that the refrigerant CM can flow through the through-flow path 32b of the internal component 32. Furthermore, the connection between the refrigerant internal component 52 and the refrigerant passage 9 is performed using a conventional connection method (joining method).

[0083] Thus, the base 24, which functions as part of the generator housing component, has two component mounting areas including two openings 31b, and functions as flanges for mounting the internal component 51 for ozone gas and the internal component 52 for refrigerant.

[0084] On the other hand, an internal component 53 for raw material gas, which serves as an internal component 32 for transferring the object, is installed in the side 110s (within the opening 31b) of the generator cover 110. Therefore, the through flow path 32b of the internal component 32 for transferring the object becomes the raw material gas inlet 130 of the internal component 53 for transferring the raw material gas. In the internal component 53 for transferring the raw material gas, the object being transferred is a raw material gas G1 such as oxygen, and the space serving as the transfer component is a receiving space S100.

[0085] Thus, in the ozone generating device 100 of the basic structure, the raw gas inlet 130, which is the through flow path 32b of the internal component 53 for raw gas, is connected to the housing space S100 in such a way that the raw gas G1 can flow to the ozone generator 101.

[0086] Additionally, an internal component 54 (high-pressure bushing 120) for a sleeve, which serves as an internal component 32 for transferring objects, is installed inside the opening 31b of the side 110s of the generator cover 110. Figure 4 As shown, the high-pressure bushing 120 itself functions as an internal component 54 for bushing.

[0087] In the internal component 54 of the bushing, one end of the relay terminal 121, which is a structural element, is electrically connected to the high-voltage cable 401, and the other end of the relay terminal 121 is electrically connected to the power supply terminal 4, which serves as the power supply path. Thus, in the internal component 54 of the bushing, the object of transmission is electricity for ozone generation, and the transmission component is the power supply terminal 4, which serves as the power supply path. Therefore, the internal component 54 of the bushing is electrically connected to the power supply terminal 4, which serves as the power supply path, in a manner that allows electricity for ozone generation to be supplied via the relay terminal 121.

[0088] The internal components 53 for the raw material gas and the internal components 54 for the casing are respectively positioned in the same direction as... Figures 1-3 The internal component 32 for object transfer shown has a substantially the same structure. That is, the side surface 110s of the generator cover 110 corresponds to the outer frame component 31. In the side surface 110s, the two openings 31b for mounting the internal component 53 for the raw material gas and the high-pressure bushing 120, and the surrounding area of ​​the two openings 31b, become the component mounting area.

[0089] Additionally, the relay terminal 121 can be provided in the object transfer internal component 32 in a manner that extends through the through flow path 32b.

[0090] Thus, the side 110s of the generator cover 110, which functions as part of the generator housing component, has two component mounting areas including two openings 31b, which function as flanges for mounting the internal component 53 for the raw material gas and the internal component 54 for the casing.

[0091] Will Figures 1-3 The object transfer constructor 30 shown is... Figures 4-6 The relationships of the ozone generating device 100 shown are summarized as follows.

[0092] The base 24 of the ozone generating device 100 and the side 110s of the generator cover 110 are respectively connected to... Figures 1-3 The outer frame component 31 shown corresponds to this. The generator housing component is composed of the base 24 and the generator cover 110.

[0093] The ozone gas internal component 51 and refrigerant internal component 52 installed on the base 24, and the raw material gas internal component 53 and sleeve internal component 54 installed on the side of the cover 110s, are respectively connected to... Figures 1-3 The object shown corresponds to the internal component 32.

[0094] Furthermore, in the base 24, the openings 31b and their surrounding areas for the ozone gas internal component 51 and the refrigerant internal component 52 respectively become component mounting areas. Similarly, in the cover side 110s, the openings 31b and their surrounding areas for the raw material gas internal component 53 and the sleeve internal component 54 respectively become component mounting areas.

[0095] Therefore, the base 24 has two component mounting areas for an internal component 51 for ozone gas and an internal component 52 for refrigerant, and the cover side 110s of the generator cover 110 has two component mounting areas for an internal component 53 for raw material gas and an internal component 54 for a sleeve.

[0096] Thus, a total of four object transfer internal components 32 are respectively installed in the four component mounting areas of the generator housing component, including the base 24 and the cover side 110s.

[0097] As described above, in the ozone generating device 100, which is the basic structure of Embodiment 1 of this disclosure, the object transfer internal component 32 is installed in the component mounting area in a highly airtight, tightly fitted state within the opening 31b without being separated from other components, even at non-cooling temperature zone TH. Furthermore, in the ozone generating device 100, the generator housing component is composed of a combination of a base 24 and a generator cover 110, and the component mounting area is a portion of the base 24 or the side 110s of the cover.

[0098] The object transfer internal component 32 has the aforementioned diameter variation property. Therefore, after the object transfer internal component 32, which is set to a state below the cooling temperature T1, is placed in the opening 31b, by setting the temperature of the object transfer internal component 32 to the non-cooling temperature range TH, the object transfer internal component 32 can be installed in the component mounting area of ​​the generator housing component in the aforementioned close-fitting mounting state.

[0099] As a result, in the ozone generating device 100 of Embodiment 1, the object transfer internal component 32 does not have any components that need to be replaced or processed during use, thus reliably avoiding a decrease in the efficiency of the ozone generating device 100.

[0100] Furthermore, components that need to be replaced include, for example, sealing components such as O-rings. Typically, O-rings, as a representative sealing component, exhibit characteristics of deterioration over time, thus requiring regular maintenance and repairs to replace them. Such maintenance is not required in the ozone generating device 100 of Embodiment 1.

[0101] Furthermore, the ozone generating device 100 of Embodiment 1 does not have a component that becomes a replacement object during the use of the object transfer internal component 32. Therefore, there is no possibility of damage to the object transfer internal component 32 and the component installation area during component replacement, thus enabling the ozone generating device 100 to have a long service life.

[0102] Furthermore, the object transfer internal component 32 provided in the ozone generating device 100 of Embodiment 1 does not have any components that become obsolete during use, thus reducing the environmental burden on the ozone generating device 100. This is because, in the ozone generating device 100 of Embodiment 1, there is no possibility of discarding sealing components such as O-rings.

[0103] In Embodiment 1, the ozone generating device 100 has an internal ozone gas component 51 installed in the component mounting area of ​​the base 24. That is, it is composed of the base 24 corresponding to the outer frame component 31 and the internal ozone gas component 51 corresponding to the object transfer internal component 32. Figures 1-3 The object transfer constructor 30 is shown.

[0104] In the ozone generating device 100 of Embodiment 1, the ozone gas internal component 51 included in the object transfer internal component 32 of the base 24, which uses the outer frame component 31 as the base 24, does not have any components that need to be replaced during use. Therefore, it is possible to reliably avoid the reduction in the operating efficiency of the ozone generating device 100 with the ozone gas internal component 51, and to achieve a long service life for the ozone generating device 100.

[0105] Furthermore, in the ozone generating device 100 of Embodiment 1, the internal ozone gas component 51 provided on the base 24 does not have any components that would become waste during use, thus reducing the environmental burden in the ozone generating device 100.

[0106] In Embodiment 1, the ozone generating device 100 has a refrigerant internal component 52 installed in the component mounting area of ​​the base 24. That is, it is composed of the base 24 corresponding to the outer frame component 31 and the refrigerant internal component 52 corresponding to the object transfer internal component 32. Figures 1-3 The object transfer constructor 30 is shown.

[0107] In the ozone generating device 100 of Embodiment 1, the refrigerant internal component 52 included in the object transfer internal component 32 of the outer frame component 31 as the base 24 does not have any components that need to be replaced during use. Therefore, it is possible to reliably avoid the reduction in the operating efficiency of the ozone generating device 100 with the refrigerant internal component 52, and to achieve a long service life of the ozone generating device 100.

[0108] Furthermore, in the ozone generating device 100 of Embodiment 1, the refrigerant internal component 52 provided on the base 24 does not have any components that would become waste during use, thus enabling the reduction of the environmental burden in the ozone generating device 100.

[0109] In Embodiment 1, the ozone generating apparatus 100 has a raw material gas internal component 53 provided in the component mounting area on the side 110s of the generator cover 110. That is, it is composed of the cover side 110s corresponding to the outer frame component 31 and the raw material gas internal component 53 corresponding to the object transfer internal component 32. Figures 1-3 The object transfer constructor 30 is shown.

[0110] In the ozone generating device 100 of Embodiment 1, the inner component 53 for transferring the raw material gas contained in the inner component 32, which is used as the object transfer inner component 32 of the outer frame member 31 as the cover side 110s, does not have any components that need to be replaced during use. Therefore, it is possible to reliably avoid the reduction in the operating efficiency of the ozone generating device 100 with the raw material gas inner component 53, and to achieve a long service life of the ozone generating device 100.

[0111] Furthermore, in the ozone generating device 100 of Embodiment 1, the internal component 53 for the raw material gas provided on the side 110s of the cover does not have any components that would become waste during use, thus the environmental burden of the ozone generating device 100 can be reduced.

[0112] In Embodiment 1, the ozone generating apparatus 100 has an internal sleeve component 54 installed as a high-pressure sleeve 120 in the component mounting area on the side 110s of the generator cover 110. That is, the cover side 110s corresponding to the outer frame component 31 and the internal sleeve component 54 corresponding to the object transfer internal component 32 constitute the apparatus. Figures 1-3 The object transfer constructor 30 is shown.

[0113] In the ozone generating device 100 of Embodiment 1, the inner sleeve component 54 included in the inner component 32 that transmits objects from the outer frame component 31 to the cover side 110s does not have any components that need to be replaced during use. Therefore, it is possible to reliably avoid the reduction in the efficiency of the ozone generating device 100 with the inner sleeve component 54, and to achieve a longer lifespan for the ozone generating device 100.

[0114] Furthermore, in the ozone generating device 100 of Embodiment 1, the internal component 54 of the sleeve provided on the side 110s of the cover does not have any components that would become waste during use, thus the environmental burden of the ozone generating device 100 can be reduced.

[0115] Furthermore, the generator housing component in the ozone generating device 100, which is the basic structure of Embodiment 1, is a combination of the base 24 and the generator cover 110. Therefore, before completing the generator housing component, the object transfer internal components 32 (51-54) can be installed on the base 24 or the generator cover 110 of the single structure relatively easily.

[0116] That is, the ozone gas internal component 51 and the refrigerant internal component 52 can be installed on the base 24, which is a single-unit structure in the stage before becoming a generator housing component, and the raw material gas internal component 53 and the sleeve internal component 54 can be installed on the cover side 110s of the generator cover 110, which is a single-unit structure in the stage before becoming a generator housing component.

[0117] As a result, during the manufacturing stage of the ozone generating device 100 of Embodiment 1, the installation efficiency of the object transfer internal component 32 can be improved.

[0118] (First variation) Figure 7 This is an explanatory diagram schematically showing the cross-sectional structure of an ozone generating device 100A, which is a first variation of Embodiment 1 of the present invention. Hereinafter, [the following will describe the cross-sectional structure of the ozone generating device 100A]. Figures 4-6 The ozone generating device 100 with the same basic structure shown is labeled with the same reference numerals and descriptions are omitted as appropriate. The description focuses on the characteristic parts of the ozone generating device 100A.

[0119] As shown in the figure, the generator housing component of the ozone generating device 100A includes a base 24A and a generator cover 110A disposed on the surface of the base 24A as the main structural elements. In a first variation, a housing space S100 covered by the generator cover 110A is formed on the surface of the base 24A.

[0120] The internal components 51 for ozone gas, 52A for refrigerant input, and 52B for refrigerant output are respectively positioned in relation to... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has the same structure. Here, the base 24A corresponds to the outer frame component 31. In the base 24A, the three openings 31b for the ozone gas internal component 51, the refrigerant input internal component 52A, and the refrigerant output internal component 52B, and the surrounding area of ​​the three openings 31b, become the component mounting area.

[0121] A refrigerant input internal component 52A, which serves as an object transfer internal component 32, is installed within the base 24A (opening 31b) of the outer frame component 31. The through flow path 32b of the object transfer internal component 32 becomes the refrigerant inlet 12A of the refrigerant input internal component 52A. In the refrigerant input internal component 52A, the object transferred is a refrigerant CM such as cooling water, and the transfer component is a refrigerant input passage 9A. The refrigerant input passage 9A is a passage for supplying refrigerant such as cooling water to the ozone generator 101.

[0122] The refrigerant inlet internal component 52A is connected to the refrigerant inlet passage 9A in such a way that the refrigerant CM can flow through the through-flow path 32b of the object transfer internal component 32. Furthermore, the connection between the refrigerant inlet internal component 52A and the refrigerant inlet passage 9A is performed using a conventional connection method (joining method).

[0123] An internal refrigerant output component 52B, which serves as an internal component 32 for object transfer, is installed within the base 24A (opening 31b) of the outer frame component 31. The through flow path 32b of the object transfer internal component 32 becomes the refrigerant outlet 12B of the refrigerant output internal component 52B. In the refrigerant output internal component 52B, the object transferred is refrigerant CM, and the transfer component is a refrigerant output passage 9B. The refrigerant output passage 9B is a passage for discharging the refrigerant supplied to the ozone generator 101.

[0124] The refrigerant outlet internal component 52B is connected to the refrigerant outlet passage 9B in such a way that the refrigerant CM can flow through the through-flow path 32b of the object transfer internal component 32. Furthermore, the connection between the refrigerant outlet internal component 52B and the refrigerant outlet passage 9B is performed using a conventional connection method (joining method).

[0125] Thus, the base 24A, which functions as part of the generator housing component, has three component mounting areas including three openings 31b, and functions as flanges for mounting the internal component 51 for ozone gas, the internal component 52A for refrigerant input, and the internal component 52B for refrigerant output.

[0126] On the other hand, an internal component 53 for the raw material gas and an internal component 54 for the casing are installed on the side 110s of the generator cover 110A. The internal component 53 for the raw material gas and the internal component 54 for the casing are respectively positioned opposite to... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has a substantially the same structure.

[0127] That is, the side surface 110s of the generator cover 110 corresponds to the outer frame component 31. In the side surface 110s, the two openings 31b for the raw material gas internal component 53 and the high pressure bushing 120 and the surrounding area of ​​each of the two openings 31b become the component mounting area.

[0128] An internal component 53 for raw material gas, which serves as an internal component 32 for transferring objects, is installed inside the opening 31b on the side 110s of the cover, which becomes the outer frame component 31. The through flow path 32b of the internal component 32 for transferring objects becomes the raw material gas inlet 130 of the internal component 53 for transferring raw material gas. In the internal component 53 for transferring raw material gas, the object to be transferred becomes the raw material gas G1, and the transfer component becomes the raw material gas passage 18.

[0129] The raw material gas passage 18 is provided for supplying raw material gas G1 to the discharge space 6 (not shown). As with the ozone generating device 100 of the basic structure, the housing space S100 can also function as a transmission component for raw material gas G1 instead of the raw material gas passage 18.

[0130] Thus, the side 110s of the generator cover 110A, which functions as part of the generator housing component, has two component mounting areas including two openings 31b, which function as flanges for mounting the internal component 53 for the raw material gas and the internal component 54 for the casing.

[0131] In addition to having the same effect as the basic structure, the ozone generating device 100A of this first modification also has the following effects.

[0132] The ozone generating device 100A of the first modification has a refrigerant input internal component 52A and a refrigerant output internal component 52B provided in the component mounting area of ​​the base 24A. That is, it is implemented in a two-unit structure by the base 24A corresponding to the outer frame component 31 and the refrigerant input internal component 52A and the refrigerant output internal component 52B corresponding to the two object transfer internal components 32. Figures 1-3 The structure shown is a constructor 30 for passing objects.

[0133] In the ozone generating device 100 of Embodiment 1, the refrigerant input internal component 52A and the refrigerant output internal component 52B included in the object transfer internal component 32 of the outer frame component 31 as the base 24A do not have components that need to be replaced during use. Therefore, it is possible to reliably avoid the reduction in the operating efficiency of the ozone generating device 100A with the refrigerant input internal component 52A and the refrigerant output internal component 52B, and to achieve a long service life for the ozone generating device 100A.

[0134] Furthermore, in the ozone generating device 100A of the first modified example, the internal component 52A for refrigerant input and the internal component 52B for refrigerant output provided on the base 24A do not have any components that would become waste objects during use, so the environmental burden in the ozone generating device 100A can be reduced.

[0135] (Second variation) Figure 8 This is an explanatory diagram schematically showing the cross-sectional structure of the ozone generating device 100B of the second modification of Embodiment 1 of this disclosure. Hereinafter, [the following will describe the structure of the ozone generating device 100B]. Figures 4-6 The ozone generating device 100 with the basic structure shown is or Figure 7 The same structural elements of the ozone generating device 100A shown in the first modified example are labeled with the same reference numerals and descriptions are omitted as appropriate. The description focuses on the characteristic parts of the ozone generating device 100B.

[0136] As shown in the figure, the generator housing component of the ozone generating device 100B includes a base 24B and a generator cover 110B disposed on the surface of the base 24B as the main structural elements. In a second variation, a housing space S100 covered by the generator cover 110B is formed on the surface of the base 24B.

[0137] The base 24B is equipped with an internal component 51 for ozone gas, an internal component 52A for refrigerant input, an internal component 52B for refrigerant output, and an internal component 53 for raw material gas.

[0138] The internal components 51 for ozone gas, 52A for refrigerant input, 52B for refrigerant output, and 53 for raw material gas are respectively positioned in the same direction as... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has the same structure. Here, the base 24B corresponds to the outer frame component 31. In the base 24B, the four openings 31b for the ozone gas internal component 51, the refrigerant input internal component 52A, the refrigerant output internal component 52B, and the raw material gas internal component 53, and the surrounding area of ​​the four openings 31b, become the component mounting area.

[0139] Thus, the base 24B, which functions as part of the generator housing component, has four component mounting areas including four openings 31b, and functions as flanges for mounting internal components 51 for ozone gas, internal components 52A for refrigerant input, internal components 52B for refrigerant output, and internal components 53 for raw material gas.

[0140] On the other hand, an internal component 54 for a bushing is installed on the side 110s of the generator cover 110B as a high-pressure bushing 120. The internal component 54 for the bushing is positioned in relation to... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has a substantially the same structure. That is, the cover side 110s of the generator cover 110 corresponds to the outer frame component 31, and in the cover side 110s, the opening 31b for the high-pressure bushing 120 and the surrounding area of ​​the opening 31b become the component mounting area.

[0141] Thus, the side 110s of the generator cover 110B, which functions as part of the generator housing component, has a material mounting area including an opening 31b, which functions as a flange for mounting the internal component 54 for the sleeve.

[0142] The ozone generating device 100B of this second modification achieves the same effect as the basic structure and the first modification.

[0143] (Third variation) Figure 9 This is an explanatory diagram schematically showing the cross-sectional structure of the ozone generating device 100C according to a third modification of Embodiment 1 of this disclosure. Hereinafter, [the following will describe the cross-sectional structure of the ozone generating device 100C according to Embodiment 1 of this disclosure]. Figures 4-6 The ozone generating device 100 with the basic structure shown is as follows. Figure 7 The ozone generating device 100A of the first modified example shown, or Figure 8 The same structural elements of the ozone generating device 100B shown in the second modified example are labeled with the same reference numerals and descriptions are omitted as appropriate. The description focuses on the characteristic parts of the ozone generating device 100C.

[0144] As shown in the figure, the generator housing component of the ozone generating device 100C is provided with a single-unit generator housing 105. The generator housing 105 is configured as a box with an internal housing space S100.

[0145] The bottom 105b of the generator housing 105 is provided with an internal component 51 for ozone gas, an internal component 52A for refrigerant input, an internal component 52B for refrigerant output, and an internal component 53 for raw material gas.

[0146] The internal components 51 for ozone gas, 52A for refrigerant input, 52B for refrigerant output, and 53 for raw material gas are respectively positioned in the same direction as... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has the same structure.

[0147] That is, the bottom 105b of the housing corresponds to the outer frame component 31. In the bottom 105b of the housing, the four openings 31b for the ozone gas internal component 51, the refrigerant input internal component 52A, the refrigerant output internal component 52B, and the raw material gas internal component 53, as well as the surrounding area of ​​the four openings 31b, become the component installation area.

[0148] Thus, the bottom 105b of the generator housing 105, which is a generator housing component, has four component mounting areas including four openings 31b, which function as flanges for mounting internal components 51 for ozone gas, internal components 52A for refrigerant input, internal components 52B for refrigerant output, and internal components 53 for raw material gas.

[0149] On the other hand, an internal component 54 for a bushing is installed on the side 105s of the generator housing 105 as a high-pressure bushing 120. The internal component 54 for the bushing is positioned in relation to... Figures 1-3 The object transfer internal component 32 in the object transfer structure 30 shown has a substantially the same structure. That is, the side 105s of the generator housing 105 corresponds to the outer frame component 31, and in the side 105s, the opening 31b for the high-pressure bushing 120 and the surrounding area of ​​the opening 31b become the component mounting area.

[0150] Thus, the side 105s of the generator housing 105, which is a generator housing component, has a material mounting area including an opening 31b, which functions as a flange for mounting the internal component 54 for the sleeve.

[0151] The ozone generating device 100C of this third modification has the same effect as the basic structure, the first modification and the second modification, and has the following inherent effects.

[0152] In the third variation of the ozone generating device 100C, the generator housing 105, which serves as the generator housing component, is a single-unit structure, thus minimizing the number of components in the generator housing component.

[0153] <Implementation Method 2> Figures 10-13 This is an explanatory diagram illustrating the installation method of the object transfer internal component 32 according to Embodiment 2 of this disclosure.

[0154] The object transfer internal component 32 becomes a structural element of the ozone generating device 100 of Embodiment 1 and the ozone generating devices 100A to 100C of the first to third modifications.

[0155] For example, in as Figures 4-6 In the ozone generating device 100 with the basic structure of Embodiment 1 shown, the base 24 or the cover side 110s of the generator cover 110 is the outer frame component 31, and the ozone gas internal component 51, the refrigerant internal component 52, the raw material gas internal component 53, and the sleeve internal component 54 are the object transfer internal components 32.

[0156] In addition, Figure 7 In the ozone generating device 100A shown as a first modification, the base 24A or the side 110s of the generator cover 110A is the outer frame component 31, and the internal components for ozone gas 51, refrigerant input 52A, refrigerant output 52B, raw material gas 53, and sleeve 54 are the object transfer internal components 32.

[0157] On the other hand, Figure 8 In the ozone generating device 100B shown as a second variation, the outer frame component 31 is the side 110s of the base 24B or generator cover 110B, and the internal components 51 for ozone gas, 52A for refrigerant input, 52B for refrigerant output, 53 for raw material gas, and 54 for casing are the internal components 32 for object transfer.

[0158] Furthermore, in Figure 9 In the ozone generating device 100C shown as a third variation, the bottom 105b or side 105s of the generator housing 105 is an outer frame component 31, and the internal components for ozone gas 51, refrigerant input 52A, refrigerant output 52B, raw material gas 53, and sleeve 54 are object transfer internal components 32.

[0159] Thus, multiple object transfer internal components 32 are installed in the component mounting area of ​​the outer frame component 31 as structural elements of the ozone generating device 100 (100A to 100C). Hereinafter, the devices collectively referred to as ozone generating device 100, 100A to 100C are sometimes referred to as "ozone generating device 100, etc."

[0160] The ozone generating device 100, etc., includes an ozone generator 101. The ozone generator 101 generates a dielectric barrier discharge in the discharge space 6, performing an ozone generation process in which the raw material gas G1 supplied to the discharge space 6 is used to generate ozone gas G2. The ozone generator 101 is housed within a housing space S100 of a generator housing component.

[0161] The containment space S100 is provided with an ozone gas passage 8 for supplying ozone gas G2 generated in the discharge space 6, a refrigerant passage 9 (refrigerant input passage 9A, refrigerant output passage 9B) for supplying refrigerant such as cooling water, a raw material gas passage 18 for supplying raw material gas G1, and a power supply terminal 4 that serves as a power supply path for power supply. Furthermore, in the basic structure of the ozone generating device 100, the containment space S100 itself functions as a transmission component for the raw material gas G1.

[0162] The following is for reference Figures 10-13 This describes the processing steps of the installation method for the internal component 32 of the object transfer. The installation method involves performing steps (a) to (c) as described below. Additionally, in Figures 10-13 For ease of explanation, the through flow path 32b provided in the internal component 32 for object transfer is omitted from the illustration.

[0163] Step (a)...as Figure 10 As shown, an outer frame component 31 with an opening 31b and an object transfer internal component 32 that is intended to be installed in the opening 31b are prepared.

[0164] The opening 31b is circular with an opening diameter d1 when viewed from above, and the internal object transfer component 32 is circular with a component diameter d2 when viewed from above. The outer peripheral surface of the internal object transfer component 32 does not have recesses such as sealing grooves.

[0165] In the outer frame component 31, the opening 31b and the area around it become the component mounting area for mounting the internal component 32 for transferring objects.

[0166] The internal component 32 for object transfer has the following diameter variation characteristics: when the specified cooling temperature is below the cooling temperature T1, the component diameter d2 of the internal component 32 for object transfer is smaller than the opening diameter d1; when the non-cooling temperature zone TH is above the cooling temperature T1 and above 0°C, the component diameter d2 becomes greater than the opening diameter d1.

[0167] The non-cooling temperature range TH is a temperature range higher than the cooling temperature T1 and above 0 °C, including the normal temperature range TR of {0 to 40 °C}. In addition, the temperature during the ozone generation process in the ozone generator 101 is also included in the temperature range of the non-cooling temperature range TH.

[0168] In Figures 10-13 it, the component diameter d2 at the non-cooling temperature range TH is denoted as the non-cooling component diameter d21, and the component diameter d2 below the cooling temperature T1 is denoted as the cooling component diameter d22. The outer frame component 31 is separated from the object to be cooled, and the temperature is always set to the non-cooling temperature range TH, so it becomes a constant opening diameter d1.

[0169] For example, in the non-cooling temperature range TH, the dimensions are set such that the non-cooling component diameter d21 of the object transfer internal component 32 and the opening diameter d1 satisfy the formula (1) {d21 = k·d1…(1)}. Here, the coefficient k is set to {k = 1.0002 to 1.0003}.

[0170] Therefore, as Figure 10 shown, when performing step (a), the non-cooling component diameter d21 of the object transfer internal component 32 is longer than the opening diameter d1 of the outer frame component 31.

[0171] After performing step (a), step (b) is performed. In addition, step (b) includes the following steps (b-1) and (b-2).

[0172] Step (b-1)… As Figure 11 shown, the object transfer internal component 32 is set to a low temperature state below the cooling temperature T1. In addition, the temperature of the outer frame component 31 is set to the non-cooling temperature range TH.

[0173] Step (b-2)… As Figure 12 shown, in the state below the cooling temperature T1, the object transfer internal component 32 is arranged in the opening portion 31b of the outer frame component 31.

[0174] By performing step (b-1), the component diameter d2 of the object transfer internal component 32 is shortened from the non-cooling component diameter d21 to the cooling component diameter d22, and the formula (2) {d22 < d1} holds. Hereinafter, this will be described in detail.

[0175] When the structural material of the object transfer internal component 32 is a corrosion-resistant alloy material such as stainless steel, due to the thermal strain ε that has a positive correlation with temperature, the component diameter d2 has the property of becoming shorter as the temperature decreases.

[0176] Therefore, by setting the temperature of the internal component 32 for transferring objects to a cooling temperature T1 that is sufficiently below 0°C, it is possible to achieve the component diameter d22 that satisfies the above formula (2) during cooling. In addition, the cooling temperature T1 is set to be sufficiently below 0°C within the range of {-270°C to -20°C}, for example, 196°C.

[0177] When step (b-2) is performed, the above equation (2) holds, so a gap 35 is generated between the outer peripheral surface of the object transfer internal component 32 and the inner peripheral surface of the opening 31b, so the object transfer internal component 32 can be arranged relatively easily in the opening 31b.

[0178] Thus, as step (b), which includes the above steps (b-1) and (b-2), a process is performed to place the object transfer internal component 32, which is set to a cooling temperature T1 or below, within the opening 31b of the component mounting area of ​​the outer frame component 31. Furthermore, the component mounting area of ​​the outer frame component 31 becomes the area of ​​the opening 31b and its surrounding area. After performing step (b), the following step (c) is performed.

[0179] Step (c)... With the object transfer internal component 32 positioned within the opening 31b of the outer frame component 31, the set temperature of the object transfer internal component 32 is raised from the cooling temperature T1 to the non-cooling temperature band TH.

[0180] Therefore, as Figure 13 As shown, an object transfer structure 30 can be obtained in which the outer frame member 31 and the object transfer inner member 32 are integrated in a state where the outer peripheral surface of the object transfer inner member 32 is in close contact with the boundary surface 33 of the inner peripheral surface of the opening 31b.

[0181] In the non-cooled temperature zone TH, the above equation (1) holds, therefore the gap 35 between the inner peripheral surface of the opening 31b and the object transfer internal component 32 is completely filled, resulting in a state where the boundary surface 33 between the outer peripheral surface of the object transfer internal component 32 and the inner peripheral surface of the opening 31b is in close contact. That is, the object transfer internal component 32 is installed in the opening 31b of the outer frame component 31 in a close-fitting installation state.

[0182] Furthermore, the ozone gas internal component 51, which serves as the object transfer internal component 32, is significantly smaller than the base 24, which serves as the outer frame component 31, and the cover side 110s of the generator cover 110. Therefore, the force (stress × contact area) exerted on the outer frame component 31 by the object transfer internal component 32 is also relatively small. Thus, in the object transfer structure 30 on which the object transfer internal component 32 is installed, even if equation (1) holds in the non-cooled temperature zone TH, the outer frame components 31, such as the base 24 and the generator cover 110, will not deform.

[0183] The operating temperature of the ozone generating device 100 when the ozone generator 101 is in operation is included in the non-cooling temperature zone TH. In addition, the temperature of the refrigerant CM, such as cooling water, is above 0°C, and the temperature of the internal component 32 transferred to the object will not fall below the cooling temperature T1 due to the supply of refrigerant CM.

[0184] Therefore, after the object transfer structure 30 is completed, the tight-fitting installation state of the object transfer internal component 32 within the opening 31b can be maintained stably.

[0185] After the object transfer structure 30 is completed, the object transfer internal component 32 is installed in the component mounting area as the ozone gas internal component 51, the refrigerant internal component 52 (refrigerant input internal component 52A, refrigerant output internal component 52B), the raw material gas internal component 53, and the sleeve internal component 54. That is, the object transfer internal component 32 becomes a structural element of the ozone generating device 100, etc.

[0186] For example, in Figures 4-6 In the case of the ozone generating device 100 of Embodiment 1 shown, an ozone gas internal component 51 and a refrigerant internal component 52, which respectively become object transfer internal components 32, are installed relative to the base 24, which becomes the outer frame component 31, by the object transfer internal component 32 installation method of Embodiment 2.

[0187] Similarly, relative to the cover side 110s of the generator cover 110, which becomes the outer frame component 31, the object transfer internal component 32 is installed with the raw material gas internal component 53 and the sleeve internal component 54, which respectively become the object transfer internal component 32, by the object transfer internal component 32 installation method of Embodiment 2.

[0188] The object transfer internal component 32 installation method of Embodiment 2 of this disclosure utilizes the aforementioned diameter variation property of the object transfer internal component 32 to perform the above-described steps (a) to (c).

[0189] By performing the above steps (b) and (c), it is not necessary to set other components such as sealing components including O-rings. The object can be transferred to the internal component 32 and installed in a close-fitting state in the opening 31b of the component mounting area of ​​the outer frame component 31.

[0190] As a result, the object transfer internal component installation method of Embodiment 2 can install the object transfer internal component 32 onto the outer frame component 31 without the need for other components such as sealing components, thus reliably avoiding the reduction in the efficiency of the ozone generating device 100 and the like caused by the replacement of other components.

[0191] In addition, the object transfer structure 30, for example in the case of the ozone generating device 100 with its basic structure, is a combination of the base 24 with the internal components 51 for ozone gas and 52 for refrigerant, and the cover side 110s of the generator cover 110 with the internal components 53 for raw material gas and 54 for the sleeve.

[0192] This disclosure has been described in detail, but the foregoing description is illustrative in all respects and is not intended to limit the disclosure. It should be understood that numerous variations not illustrated can be conceived without departing from the scope of this disclosure.
