In this type of ozonizer, 90% or more of the discharge power becomes heat, which hinders the production of ozone. Therefore, it is necessary to cool the electrodes. Examples of this cooling method include cooling with water in a cooling tower, cooling with water in a chiller, cooling with disposable cooling water, and cooling with air cooling in a radiation fin.

An aftercooler 5 is provided in the main body 1. 6 is an air tube 4

Further, 11 is an operation panel which is connected to a power source and grounded, 12 is a slide transformer, and 13 is a high voltage transformer, which are connected to the main body 1 through wiring 14. Further, 15 is a cooling water pipe, which penetrates the main body 1. 16 is a valve.

In the above structure, the air compressed by the compressor 2 passes through the aftercooler 5 in the main body 1 via the air pipe 4, and the aftercooler 5 is cooled together with the main body 1 by the cooling water. The compressed air further passes through the air pipe 4, and the prefilter 6 removes moisture. Further, the compressed air alternately passes through the dryers 7 and 8 via the switching valve 9 and is dried by the desiccant. Conversely, the moist desiccant is dried by the dry air, at which time the moist air is expelled via the valve 16. On the other hand, a power source is connected to the main body 1 via an operation panel 11, a slide transformer 12, a high voltage transformer 13, and a wiring 14. Further, cooling water is passed through the cooling water pipe 15 to the main body 1 to be cooled.

In the above-mentioned conventional ozonizer, in case of water cooling by the cooling tower, piping work and replenishment of cooling water are required, and in case of water cooling by the chiller, power consumption increases. In addition, piping work is required even in the case of water cooling using disposable cooling water, and the water consumption increases. Furthermore, it is difficult to manufacture an airtight container in the case of air cooling with a radiation fin. Further, in the cylindrical tube type ozonizer shown in FIG. 5, although it is strong against pressure because it is cylindrical, it is necessary to supply cooling water from the outside.
Further, in the case of the flat plate type ozonizer shown in FIG. 6, air cooling was easy, but it was easy to break because it had a flat plate shape.

The present invention has been made in order to solve the above problems, does not require replenishment or disposal of cooling water, has low power consumption for cooling, and can be used to manufacture pipes and radiators. An object is to obtain an easy electrode cooling device for an ozonizer.
