Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an ozone generator used in an air purifying device that deodorizes or sterilizes air.

[Prior art]

There is a method that uses ozone to deodorize or sterilize the air, or to perform both at the same time. Among conventional air purifying devices of this type, there is one in which an ozone generator is provided separately from an electrostatic precipitator, and ozone generated by the ozone generator is guided to the electrostatic precipitator. A conventional ozone generator of this type is explained with reference to Fig. 1.
2, 3, and 4 are electrodes, and 1, 2 and 3, 4 are paired, respectively, and air passages 5,
6 is formed. Dielectrics 7 and 8 are provided inside the electrodes 2 and 3, and an AC power source 9 is connected to the electrodes 1, 2, 3, and 4 as shown.

The conventional ozone generator configured in this manner allows air to flow in the direction of the arrows through the air passages 5 and 6 formed between the electrodes 1 and 2 and between the electrodes 3 and 4, and also applies a high voltage from the AC power source 9. Upon application and discharge, the air is deodorized and sterilized by the ozone produced throughout the airflow area. However, in this device, the air passages 5, 6
There was a problem in that the ozone generated within the electrodes was trapped around the electrodes 1, 2, 3, and 4, suppressing the generation of new ozone.

Therefore, as shown in Fig. 2, the number of dielectrics is increased as indicated by symbols 10, 11, 12, and
Electrodes 14, 15, 16, 17 were attached to each of these dielectrics 10, 11, 12, 13 at intervals, and an AC power source 18 was connected to the electrodes 14, 16 and the electrodes 15, 17 as shown in the figure. A method was also devised in which the air to be treated was made to flow through the air passages 19, 20, 21 formed between the dielectrics 10, 11, 12, 13 as shown by the arrows.
This could not fundamentally solve the problem of the one in Figure 1.

[Purpose of invention]

This idea solves the problems of the conventional one,
The object of the present invention is to provide an ozone generator that generates a large amount of ozone and can process a large amount of air.

[Structure of the idea]

In order to achieve the above-mentioned purpose, this invention has a plurality of electrodes fixed in parallel, and a plurality of dielectric plates with through holes bored between adjacent electrodes, parallel to each other at intervals, and parallel to each other in the direction of air flow. placed diagonally,
The structure is such that both poles of an AC power source are alternately connected to the electrodes.

〔Example〕

Next, an example of this invention is shown in Figs. 3 and 4.
To explain the figures, 22, 23, 24, 25
is a dielectric plate made of synthetic resin, on which a plurality of electrodes 26 and 27 are arranged alternately as shown by symbols A and B, and a through hole 28 is bored between these electrodes 26 and 27. It is something that These dielectric plates 22, 23, 24, and 25 are arranged parallel to each other as shown in FIG. It is connected.

In this device configured in this way, the airflow flows obliquely to the dielectric plates 22, 23, 24, and 25, which creates turbulent airflow around the electrodes 26 and 27, and no ozone remains, so new ozone is generated. will occur efficiently. In the device of the example,
Electrodes 26, 27 of dielectric plates 22, 23, 24, 25
The same dielectric plates 22, 23, 2 with a gap of 5 mm
The pitch of electrodes 26 and 27 on 4 and 25 is 2 mm, and the width of a single electrode is 0.5 mm, and a 5 kHz AC voltage is applied.
Good results were obtained by applying 5kV. This is illustrated in FIG. 5, which shows the relationship between the amount of passing air and the amount of ozone generated. In this figure, the one in Figure 1 is the one in Figure 2, and these are as follows.
It can be seen that the amount of ozone generated is smaller than that of this invention shown in .

[Effect of idea]

This idea fixes multiple electrodes as mentioned above,
Since a plurality of dielectric plates with through holes bored between the electrodes are arranged in parallel at intervals and diagonally to the air flow direction, the passing air causes turbulence, so the electrode 2
This has the effect that ozone and ions do not remain in the vicinity of 6 and 27, and new ozone is actively generated (approximately 50% more than the conventional one).
