Abstract

PURPOSE:To obtain an ozonizer capable of efficiently generating O3 even in an area where there is no power supply equipment by using the power generated by a solar battery and/or an accumulator connected to the solar battery as a power source for driving an O3 generating means. CONSTITUTION:The air as raw gas is introduced 201 into the ozonizer provided with a solar battery and ozonized, and the generated ozone is discharged 202. Meantime, the power from a solar battery 101 is charged into the accumulator 103. A switch 104 is then turned on, the power of the accumulator 103 is converted into AC by an oscillating transistor 106, and a voltage is boosted by a booster transformer 109 and impressed on the electrodes 101 and 111. Consequently, a silent discharge is generated in a discharging gap between a stainless steel pipe 203 for circulating cooling water and a glass tube 204 to generate O3. O3 is easily obtained by this method even in an area where there is no power source equipment such as a commercial power source, provided light energy is available.

This invention relates to a movable solar cell-equipped ozone generator used for deodorization, decolorization, and medical purposes.

[Prior Art and Problems to be Solved by the Invention] Ozone is used not only as a water treatment agent for disinfection, but also for decolorizing and deodorizing, for coagulation effects, for improving the activity of effective bacteria, for medical purposes,
Ozone generators have been extensively researched in recent years because of their extremely wide range of uses.

Figure 3 shows a typical example of a conventional ozone generator. In the figure, 301 is a raw material gas inlet;
02 is an ozonized gas outlet, 3゜3 is a stainless steel tube for cooling water circulation, 304 is a glass tube, 305 is a discharge electrode, 30
6 is a step-up transformer.

Raw material gas such as air is introduced from a raw material gas inlet 301, and is passed through a stainless steel pipe 303 and a glass pipe 304 for cooling water circulation.
Ozone is produced by the silent discharge that occurs in the discharge gap between.

Alternating current, pulses, etc. are used as the applied voltage, but in recent years, research using nanosecond pulses with a steep rise has been actively conducted with the aim of improving generation efficiency.

Also, attempts to increase the production efficiency by adding Ar or He to the raw material gas have been successful.

However, in conventional ozone generators, even though the gas composition changes on the upstream and downstream sides of the raw material gas flow, the discharge electrodes inside the ozone generator are all connected to the same power source. Because the power was being supplied from the reactor, it was not possible to independently control the discharge voltage and input power according to the gas composition, and it was not possible to sufficiently increase the ozone production efficiency.

Further, conventional ozone generators cannot be used in areas without power supply facilities such as commercial electric power, and there is a need for an apparatus that can be used in such areas.

[Object of the Invention] The present invention has been made to solve the problems of the prior art described above, and its purpose is to efficiently generate ozone even in areas without power supply facilities.

[Means and effects for solving the problem] As a means for solving the problem, the present invention includes an ozone generating means, a solar cell, and a secondary battery that stores the electromotive force of the solar cell. The present invention provides an ozone generator with a solar cell, characterized in that the ozone generating means is driven by the electric power of the secondary battery and/or the electromotive force of the solar cell to generate ozone.

Further, the ozone generating means has an electrode divided into two or more stages with respect to the flow direction of the raw material gas for discharging in the raw material gas, and a different voltage and current are applied to each of the electrodes. It is an object of the present invention to achieve the above object with an ozone generator equipped with a solar cell, which is characterized by having means for applying voltage.

That is, the ozone generator with a solar cell of the present invention consists of an ozone generator main body, a solar cell attached to, for example, the top surface of the ozone generator main body, and a secondary battery connected to the solar cell. Since it does not use any cables, etc., it can be moved without a cord. Furthermore, the electrodes of the ozone generator are divided into two or more stages in the flow direction of the raw material gas, and it is possible to apply a voltage and current depending on the ingredients of the raw material gas to each stage, which enables efficient ozone generation. Can generate.

According to the present invention, ozone can be efficiently generated even in areas without power supply facilities as long as light energy is obtained, and is effective for sterilizing and deodorizing drinking water in undeveloped areas, for example. demonstrate. In particular, in the summer when the need for sterilization and deodorization is high, the output of the solar cell is high and can sufficiently meet the needs.

Furthermore, by providing a solar cell on the top surface of the device, sunlight can be used efficiently.
