Description of the Related Art Ozone generators have been used for a long time, as is known from the Siemens ozone tube, etc., but even the present devices have extremely low electric power efficiency for ozone generation. Analyzing the ozone generation efficiency, 1) the dryness of the oxygen-containing gas (hereinafter simply referred to as air) as the raw material gas is high, 2) the temperature of the air is low, and 3) the supply amount of air. Many, and contact the applied electrode evenly 4)
It is said that the ozone yield increases due to factors such as high air pressure, 5) large input power (voltage × frequency), and the like. Then, based on such a design concept, various proposals have been conventionally made.

案のオゾン発生装置では、基板がセラミックであるため
加工が容易でない、という問題もあった。For example, a linear application electrode formed by metallization of tungsten or the like is provided on the surface of a flaky alumina ceramic substrate, a plate-shaped induction electrode is embedded inside the ceramic substrate, and between these electrodes, A so-called creeping discharge type flat plate type ozone generator for applying an alternating high voltage to generate ozone has been proposed (for example, Japanese Patent Publication No.
32202). However, although the proposed ozone generator is well cooled and is extremely compact, it is an ozone generator composed of a single ceramic substrate. Since it is necessary to perform cooling to remove heat due to, dew condensation may occur on the substrate surface, and in particular, a delicate moisture film tends to be formed on the microscopic uneven surface of the ceramic surface,
Therefore, there is a fatal problem that the capacitance is changed, and eventually the discharge failure in the creeping discharge is induced. Therefore, it is possible to incorporate a heater into the ceramic substrate to prevent dew condensation by heating, but since it is a single substrate, heating with a heater would rather reduce the ozone yield. There was an attached problem of inviting. This phenomenon also causes nitrogen in the raw material air to be converted into NOx and cause nitrate to adhere to the application electrode on the substrate surface, which also causes discharge failure. Further, in the proposed ozone generator, there is a problem that the substrate is made of ceramic and thus is not easily processed.

いう問題があった。On the other hand, as the ozone generator, a cylindrical type has been known for a long time like a Jemens tube as compared with the flat plate type. In this cylindrical ozone generator, both electrodes are isolated by a discharge gap. Therefore, even if dew condensation occurs on the ozone generator, the discharge failure as much as the above-mentioned creeping discharge does not occur. However, both the cylindrical shape and the flat plate shape have a structure in which the length of the applied electrode cannot be adjusted, and the applied electrode is consumed (ozone is a strong oxidizing agent next to fluorine in the natural oxidizer). If it is a chemical agent and the applied electrode is easily consumed by spattering), the structure is such that only this electrode cannot be replaced, so there was the problem that the entire ozone generator had to be replaced. .

増大が図られる。The main body casing 1 is composed of a cubic base 6 and a tube 7 standing upright in the center of the base 6 and having an inner diameter of 12 mmφ. The super heat resistant epoxy resin forming the body casing 1 is an insulator capable of so-called silent discharge that avoids locally concentrated discharge, and is excellent in heat resistance, acid resistance, pressure resistance and strength. So-called super engineering plastics, for example, those in which a large amount of aromatics are introduced into the structure of an epoxy polymer or the number of epoxy groups is increased. In addition, when improving strength by corona resistance etc., borosilicate glass powder may be mixed. Since the main body casing 1 is molded with such a resin, the inner surface of the tubular body 7 becomes smooth and the adhesion of water is reduced. Moreover, it is easy to process and the service life can be increased.

In order to cause a cyclone or a swirl in the inside, an introduction hole 9 that is open in the tangential direction of the inner surface is formed. A raw material supply side joint 10 is screwed to the outer end of the introduction hole 9. Further, the ozone extraction side joint 1 is attached to the tip of the pipe body 7.
1 is screwed on.

よる消耗を防ぐことになる。The applying electrode rod 2 has a cylindrical leg portion 13 having a flange 12 at the lower end and a diameter of 8 mmφ, and a diameter of 10 mmφ.
It is composed of a cylindrical applying rod 14 having a length of about 50 mm. The leg portion 13 and the applying rod 14 are inserted into the tube body 7 and the through hole 8, and after the insertion, the flange 12 is brought into contact with the outer surface of the base 6 to tighten the tie rods 15, 15. In this way, when the applying rod 14 is inserted into the tube body 7 and the through hole 8 and set concentrically, a donut-shaped discharge gap having a width of about 1 mm can be formed, and it can be used even at a low applied voltage. There is. The applying rod 14
A plurality of grooves 16 having a depth of 0.25 mm are formed on the outer circumference of the at equal intervals in the axial direction. Further, a concave portion 17 having a slight depth is provided in the tip end surface of the applying rod 14, and a notch is provided around the concave portion 17 at a position corresponding to the groove 16. Therefore, when a tungsten wire 18 having a diameter of 0.5 mmφ for the applying electrode is wound around the applying rod 14 along the groove 16 and the notch, a desired applying electrode length can be obtained. For example, the length of the applied electrode is 10 cm when it is hung on one strand, and it is 20 cm when it is hung on two strands. Moreover, since the tungsten wire 18 fits in the groove 16, it can be installed without being displaced.
Since the tungsten wire 18 is almost half buried in the groove 16,
Since the application electrode has a semicircular cross section and faces the induction electrode body 3, a high electron temperature is obtained and consumption due to sputtering or oxidation is prevented.

A horizontal hole 20 through which both ends of the tungsten wire 18 are bundled and inserted is penetrated. Therefore, each end of each of the plurality of tungsten wires 18 wound around the applying rod 14 is provided with a horizontal hole 20.
When the application terminal 5 is screwed into the screw hole 18, the tip of the application terminal 5 can be crimped to both ends of the tungsten wire 18 for connection. The induction electrode body 3 is formed by mixing a powder of a conductive material such as carbon black into a super heat resistant epoxy resin to form an induction electrode. The induction electrode body 3 is composed of a plate body 21 having a square fin 4 in a plan view and a square heat sink end body 22, and the finned plate body 21 is connected to the main casing 1. The pipes 7 are fitted onto the base 6 and stacked in order, and finally the heat sink end 22
Are set and tightened by the tie rod 15 to set. A ground terminal hole 23 is formed on the outside of the heat sink end body 22.

A rod 2 for applying an electrode, which has a single strand of tungsten wire 18, is set in the main body casing 1. Next, by connecting to the raw material supply side joint 10 so as to supply the purified raw material air pressurized by a compressor (not shown),
Since the raw material air is sent from the introduction hole 9 to the through hole 8 in the tangential direction, the raw material air becomes a cyclone or a spiral shape, passes through the discharge gap, and evenly contacts the tungsten wire 18. At this time, even if dew condensation forms on the inner surface of the pipe body 7, it passes while blowing it off. Therefore, the ozone yield is high. Next, in order to obtain the air in which the amount of ozone is increased, the number of the tungsten wires 18 may be increased without changing the applied power, the pressure and the temperature of the raw material air, and the like. Furthermore, if the tungsten wire 18 for the applying electrode is consumed, it may be replaced with a new tungsten wire.

Not only that, if it is set, it will be well compatible with the resin-made main body casing 1, and it has a feature that dew condensation is unlikely to occur on the inner surface of the tube body 7 of the main body casing 1.
