DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an ozonizer for producing ozone gas by applying silent corona discharge to general air or oxygen gas.

2. Description of the Related Art Conventionally, this type of ozonizer has a cylindrical wall surface of an air or oxygen gas passage with a dielectric layer and a linear layer provided on the surface of the dielectric layer. A cylindrical battery case is provided in the cylindrical passage, and a high-voltage, high-current power source is connected between both 'α poles to generate a silent corona discharge in the cylindrical passage, and the air or oxygen gas passing therethrough is converted to ozone gas. .

Most of the power consumed at this time becomes heat, and each electrode and diode
body, increases the temperature of the ozone gas, reduces the ozone generation efficiency, and deteriorates the ozone generation area, the wall surface of the air or oxygen gas passageway, which is exposed to the plume. do.

Since this linear mixture is generally printed and printed on a green sheet as an inducer, it is almost impossible to repair it if it deteriorates as described above.

The problem that the invention seeks to solve The ozonizer of the present invention is exposed to a dielectric wall.

If the linear electrode used in the test has deteriorated due to the heat generated during ozone generation or the action of ozone gas.

It is an object of this invention to solve the problems of the conventional ozonizer by combining these problems so that they can be easily repaired.

Means for Solving the Problem A tape-shaped electrode is formed into a cylindrical shape on the circumferential surface of a cylindrical dielectric material, and the tape-like electrode is crimped by its elasticity, and the cylindrical electrode is inserted through at least a part of the thickness of the cylindrical dielectric material. are arranged concentrically, a high 1TL wave AC power source is connected between the tape-shaped electrode and the cylindrical one tower, and the tape-shaped electrode is exposed to the ozone 11S area.

A high frequency AC power source is applied between the coiled electrode crimped to the circumferential surface of the working cylindrical dielectric body and one cylindrical dielectric body, and a silent corona discharge between them is generated in the ozonation area. Ozone is generated by causing this to act on air or oxygen supplied to the ozonization area.

When the linear electrode exposed to this area deteriorates due to the above heat generation and ozone gas generated by The electrode is then deformed and separated from its circumferential surface, the electrode is removed from the circumferential surface of the dielectric, and another new vine-like electrode is inserted against its own elasticity so that its inner diameter increases. It is deformed and placed on the circumferential surface of the dielectric in that state.

Then, by solving the external force and using its elasticity, #electric body (QI4
It is crimped onto a surface.

At that time, these are bonded together with an adhesive if necessary.

Embodiment An embodiment of the present invention will be described with reference to Figures 1 and 2.1 A tape-shaped linear electrode 2 formed in a spiral shape on the outer circumferential surface of a cylindrical dielectric 1 is crimped with its elasticity. A cylindrical electrode 3 is buried concentrically within the thickness of the dielectric 1, and a high frequency AC power source 4 is directly connected between the cylindrical electrode 3 and the linear electrode 2. An outer cylinder 6 is provided outside the linear cylinder 2 with an ozone generation chamber 5 interposed therebetween, and a casing 8 is provided outside the outer cylinder 6 with an outer cooling chamber 7 interposed therebetween.

Furthermore, an inner cooling chamber 9 is provided inside the dielectric 1.

The aforementioned ozone generation chamber 5 is provided with a gas inlet 10.

From this, a gas to be ozonated such as air or oxygen is supplied.

Also, a high frequency AC power source is applied between the linear electric value 2 and the cylindrical electric image 3, and a silent corona discharge is generated during this time, and this acts on the aforementioned gas flowing through the ozone generation M5 to form ozone gas. The gas is discharged from the gas outlet 11 and taken out to the outside.

Further, the outer cooling chamber 7 is provided with a refrigerant port 12 and a refrigerant outlet 13, and a refrigerant such as liquid or gas is allowed to flow into the refrigerant M7 to cool the ozone generation chamber 5 from the outside, thereby improving ozone generation efficiency. It is something to do.

The inner cooling chamber 9 is also provided with a refrigerant port 14 and a refrigerant outlet 15, so that the refrigerant flows into the cooling chamber 9 to cool the ozone generation chamber 5 from inside.

If the linear electrode 2 exposed to the ozone generation chamber 5 is worn out due to the ozone gas generated therein and the heat generated during its generation, the cylindrical dielectric body 1 is taken out of the casing 8,
The direction in which the inner diameter of the linear electrode 2 is increased, that is, ? Twist in the direction of arrow A2 in Figure 3 to separate it from the cylindrical electrical conductor 1 and remove it with the 70-shaped head.

Next, prepare pole 1 of another layered line.

Twist the ring center slightly to increase its diameter,
When the cylindrical dielectric 1 is inserted into this with its head and the torsional force mentioned above is released, it returns to its original state due to its elasticity, reduces the inner diameter, and is crimped to the outer peripheral surface of the cylindrical shape itself. It is.

More than 1 figure? Although the present invention has been described with reference to the embodiment shown in Figure 3, the present invention is not limited thereto, and can be implemented with partial changes and additions within the scope of the gist of the present invention. be.

For example, in the embodiment described in @, a case has been described in which the bulge-like rod-shaped electrode 2 is crimped onto the outer circumferential surface of the cylindrical dielectric 1, but it may also be crimped onto the inner 1# surface.

FIG.
It is constantly crimped on the inner surface of the

In addition, in the figure, 16 is an inner cylinder provided inside the ozone generation chamber 5, and is a part that separates the ozone generation chamber 5 and the inner cooling chamber 9.

Also, the drawing symbols in the same figure are 1. ? Parts that are equivalent to those in Figures 1 to 2 have the same names and functions.

In both of the above two embodiments, the spiral linear electrode 2, ρ
is crimped to either the outside or the outside of the circumferential surface of the cylindrical dielectric 210 by its own elasticity, but it may also be affixed with adhesive, or a combination of crimping by elasticity and fixation by adhesive may be used. It is possible.

In these cases, their fixation can be made more secure than when only crimping is used, but on the other hand, when replacing one coiled pole n with another, the worn one and the cylindrical electrode 210 may peel off from the circumferential surface. This operation takes longer than when crimping using only elasticity.

Effects In this invention, a wire-shaped pole formed in a coiled manner is crimped onto the circumferential surface of a cylindrical dielectric material using its elasticity, so that this wire-shaped electrode has the following properties:
When the ozonizer wears out due to exposure to ozone gas and high temperatures that are unavoidable due to the nature of the ozonizer, it can be replaced with a new one and used again. It can withstand long-term use compared to non-replaceable items that are printed and baked on.

In addition, since the coiled pole is crimped onto the inner surface of the dielectric material by its own elasticity, its installation and removal operations are extremely simple.
Its replacement operation is easy.
