Description

  The present invention relates to a gap spacer disposed in an ozone generator tube in an ozone generator for producing ozone used for water and sewage treatment, wastewater treatment, deodorization / sterilization treatment, and the like. Specifically, the present invention relates to a gap spacer between electrodes disposed between two electrodes in an ozone generation tube in an ozone generator that produces ozone used for water treatment, deodorization / sterilization treatment, and the like. Furthermore, the present invention relates to an ozone generation tube in which the gap spacer is disposed and an ozone generation device including the ozone generation tube.

  Ozone generators are used for sterilization, disinfection, deodorization, cleaning, etc. in various industries ranging from pulp and paper industry, semiconductor cleaning, water and sewage treatment, factory wastewater treatment, etc. to general household deodorization. In recent years, especially in the pulp and paper industry, it is required to increase the ozone concentration of the ozone-containing gas, and various studies have been conducted to achieve this. As one method for achieving a higher ozone concentration, a method of shortening the discharge gap length between two electrodes is known, and the discharge gap length in the ozone generator tube in the ozone generator is in a direction of shortening. . Currently, the gap length of high-density ozone generators in practical use has been achieved up to 0.3 mm, and a method for further shortening the gap length is being studied, but a practical and effective method has yet to be announced. Not.

  An example of a gap maintaining method used in a conventional ozone generator is shown in FIG. 12 (see Patent Document 1). In a conventional gap holding method, a gap spacer in which a SUS plate is welded and fixed to an electrode has been used. That is, it is composed of a ground electrode (3) and a high voltage electrode (2) (hereinafter also referred to as a center electrode) disposed inside the ground electrode (3), and has a dielectric layer (not shown) between two electrodes. The gap is held by the SUS plate welding spacer (1). This SUS plate spacer is welded to the ground electrode. This SUS plate spacer is a method for supporting an electrode with a very small area (for example, 5 mm × 10 mm), and aims to minimize the gap area in the discharge space and increase the discharge area. For example, a method has been used in which the SUS plate spacer is supported on the cylindrical high-voltage electrode side at four points from the vicinity of both end portions at approximately 90 ° intervals and provided at equal intervals.

Japanese Patent Laid-Open No. 11-139809 (page 4, FIG. 1)

When configuring an ozone generator, the parallelism of the opposing electrodes becomes very sensitive. That is, if the degree of parallelism of the opposing electrodes is not good, the gap length of the discharge space changes depending on the location, so that the discharge becomes non-uniform and the ozone concentration becomes non-uniform depending on the flow path.
The gap holding method in which the SUS plate is fixed by welding in the above-described prior art is a method for holding a gap between electrodes in a very small area. The range can exceed 10%. If the gap length is biased, discharge non-uniformity occurs, which causes a problem of reducing the total ozone concentration. In addition, when this method is used, a complicated operation of overlay welding the SUS plate to the electrode is essential, and if the welding process can be omitted, a gap holding operation by welding becomes unnecessary. In other words, it is connected to reduction in production cost and improvement in efficiency.

  Accordingly, an object of the present invention is to provide a technique that can easily and accurately hold the gap between the ground electrode and the high-voltage electrode in the ozone generation tube, that is, a gap spacer that can uniformly hold the discharge space. . In addition, the object of the present invention is that the above-mentioned gap spacer can be produced easily and efficiently, and the welding process, which is essential when providing the gap spacer between the electrodes in the conventional method, becomes unnecessary when the gap spacer of the present invention is disposed. It is to provide a gap spacer that can be easily disposed between a ground electrode and a high voltage electrode. In particular, it is an object to provide a spacer that can hold the discharge space even in the longitudinal direction of the discharge electrode and can easily and accurately hold the gap. Moreover, it is providing the ozone generator tube provided with the gap spacer, and an ozone generator provided with them.

  As a result of diligent research to solve the above-mentioned problems, the inventors of the present invention have generated ozone that includes a cylindrical ground electrode having both ends opened and a high-voltage electrode disposed inside the ground electrode via a gap. In an ozone generator that has a tube and a housing that contains an ozone generator tube, and generates ozone by the discharge of a source gas containing oxygen, a metal wire deformed into a simple shape like a U-shaped gap length It is found that the gap length can be accurately held by a simple operation of placing it between the electrodes as a holding spacer, and that the gap length can be easily determined by freely selecting the thickness of the metal wire. Further research has been made to arrive at the present invention.

The gap spacer in the present invention is preferably made of at least one selected from a metal rod, a metal pipe, a metal plate, a resin rod, a resin pipe, and a resin plate. Here, the metal rod means a metal elongated continuous body having a circular or elliptical cross-sectional shape, and examples thereof include a metal wire and a metal round bar. A metal pipe means a hollow metal rod. The metal plate means a metal elongated continuous body having a rectangular cross-sectional shape. The resin rod means that the shape is the same as that of a metal rod, but it is made of resin. Similarly, the resin pipe has the same shape as the metal pipe, and it means that it is made of resin. Similarly, the resin plate has the same shape as the metal plate, but it means that it is made of resin.
These metal materials or resin materials are not particularly limited as long as they are excellent in ozone resistance, but more preferable materials are materials that can be welded or bonded together. Preferable materials include stainless steel conventionally used as a spacer, aluminum, brass, nickel and the like. The most preferred material is stainless steel. It is also possible to use ozone-resistant resins such as fluorine resins and chlorendic acid resins. Since the above rod, pipe, and plate maintain the gap length between the electrodes, the thickness of the rod, pipe, plate, etc. to be used can be selected according to the desired gap length. The metal or resin is convenient because it is easy to process and easy to use during assembly.

In the present invention, a gap spacer can be produced by selecting only one material selected from the metal or resin rods, pipes, and plates and bending them. Alternatively, preparing a plurality of the above materials, then bending them appropriately and combining the materials and the bent materials as appropriate, and bonding them together with welding, bonding or welding to produce the spacer Is also possible. The bending process, the welding process, and the bonding process are already widely known. In the present invention, a general bending process, a welding process, and an adhesive process can be used. In the bonding process, it is necessary to bond the materials to each other using an ozone-resistant adhesive.

Things are preferred.

Hereinafter, a representative example of the shape of a gap spacer when a metal wire is used as a material for producing the gap spacer will be described. The gap spacer has two metal wires (first sides) having a predetermined thickness and width and facing each other. Each of the end portions of the two metal lines (first side) and one metal line (second side) are connected so as to form an angle (acute angle, right angle, or obtuse angle) with each other. A gap spacer having a shape is preferable (for example, FIG. 1), and a gap spacer including the shape is also preferable (for example, FIGS. 7 and 9).
As an example of the gap spacer including the above-mentioned shape, one end of the gap spacer in which the first side and the second side are connected and one metal line are at an angle (acute angle, right angle, Or the other end of the metal wire and a new metal wire are connected to form an angle (acute angle, right angle, or obtuse angle) with each other, Hereinafter, the same operation is performed, and a gap spacer having a shape in which metal wires (sides) are connected so as to form an angle (acute angle, right angle, or obtuse angle) with each other can be cited. However, in this case, it is necessary to connect all the metal wires (sides) so as to be substantially the same plane, and to prevent the metal wires (sides) from overlapping each other. Among these gap spacers, a gap spacer is particularly preferable in which one metal line (side) and another metal line (side) are connected to form a right angle.
Further, the gap spacer may be manufactured by applying the same method as described above to the other end of the gap spacer where the first side and the second side are connected.

The gap spacer having such a shape can be arranged on the ozone generating tube by a general method. The ozone generating tube here is not particularly limited as long as it is a general ozone generating tube, but it is necessary that at least one electrode of the counter electrode in the ozone generating tube is provided with a dielectric layer.
As a typical method of arranging the gap spacer in the ozone generating tube, for example, when arranging the gap spacer shown in FIG. By hooking and placing the first side in the longitudinal direction of the center electrode, the gap spacer can be easily arranged on the ozone generating tube. That is, the gap spacer of the present invention preferably has a hook portion and a gap length holding portion. Further, the gap spacer may be arranged in the ozone generating tube by fitting the second side of the gap spacer into the central electrode of the ozone generating tube and placing the first side in the longitudinal direction of the central electrode.
When the gap spacer of the present invention is disposed on the ozone generating tube, the present invention does not require welding work compared to the conventional method, and can be easily and efficiently disposed and operated, and the gap spacer can be easily disposed. . Furthermore, according to the method of the present invention, an ozone generating tube having a short gap length can be easily manufactured, an ozone generating tube having an arbitrary gap length can be easily manufactured, and high concentration ozone can be produced. It made it possible to manufacture. In addition, what is necessary is just to use a general apparatus also for the said ozone generator.

  According to the present invention, it is possible to provide a metal rod gap spacer that is easy to manufacture and can hold an accurate gap. In addition, the gap length can be made shorter than before. The gap spacer can be easily disposed on the counter electrode. If an ozone generator having an ozone generating tube having this counter electrode is used, high-concentration ozone can be easily obtained, which is extremely practical.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described below with reference to the drawings. The following description is an example using a SUS metal wire (hereinafter referred to as a metal wire) as a representative example.
FIG. 1 shows an example of a gap spacer (hereinafter sometimes referred to as a spacer) of the present invention, and a plane viewed from one of the counter electrodes and the side surface of the center electrode when the spacer is disposed between the electrodes. The spacer here has a substantially U-shaped form. The length of the central side of the spacer is not particularly limited. Further, the two sides connected to both ends of the central side of the spacer are parallel to each other, have the same length, and are connected so as to form a right angle between the central side and the side.
Although not shown in FIG. 1, the following spacers also belong to the present invention as spacers similar to the spacers shown in FIG. The lengths of the two sides connected to both ends of the central side of the spacer are not particularly limited, and the lengths of the two sides may be the same or different. It is preferable that both ends of the central side and the side connected to the part are connected so as to form a right angle with each other, but they may be connected so as to form an acute angle or an obtuse angle. It may be connected. Further, one end of the central side and one side may be connected to form an acute angle, and the other end of the central side and the other side may be connected to form an obtuse angle.
The spacer can be manufactured by bending a single metal wire, or can be manufactured by welding the ends of two metal wires to both ends of a single metal wire. It can also be produced by bonding the end portions with an adhesive.
The central side of the spacer is hooked on the arc portion of the center electrode, and the gap is held by the metal wire in contact with the discharge surface. If two spacers are arranged on both ends of the center electrode in a diagonal direction, the gap length between the center electrode and the ground electrode can be accurately maintained by a simple operation.

  FIG. 2 shows an example in which the same spacer as the spacer shown in FIG. 1 is arranged between the counter electrodes so as to be different from FIG. That is, in the counter electrode similar to FIG. 1, when two spacers are arranged at opposite ends of the center electrode at the diagonal diagonal and the spacer positions at both ends are perpendicular to each other, The gap length with the ground electrode can be accurately maintained with a simple operation.

FIG. 3 shows a spacer different from the above of the present invention, and a plane viewed from one of the counter electrodes and the side surface of the center electrode when the spacer is disposed between the electrodes. The spacer here is substantially U-shaped like the spacer shown in FIG. 1, but the portion different from the spacer in FIG. 1 is on a horizontal plane including two sides whose central sides are opposite to each other.

The central side of the spacer is hooked on the chord portion of the center electrode, and the gap is held by a metal wire in contact with the discharge surface. If two spacers are arranged on both ends of the center electrode in a diagonal direction, the gap length between the center electrode and the ground electrode can be accurately maintained by a simple operation.
The spacer of FIG. 3 is characterized in that, compared with the spacer of FIG. 1, mainly when ozone-containing raw material gas containing oxygen is introduced between the counter electrodes, the raw material gas is smoothly introduced and ozone having a high ozone concentration is introduced. Is that you can get.

The relationship between FIG. 3 and FIG. 4 is substantially the same as the relationship between FIG. 1 and FIG. That is, in the counter electrode similar to FIG. 3, two spacers shown in FIG. 3 are arranged at the opposite ends of the center electrode at opposite ends, and the positions of the spacers at both ends are perpendicular to each other. Then, the gap length between the center electrode and the ground electrode can be accurately maintained with a simple operation.

The spacer here can be said to be the spacer shown in FIG. 1 in which the lengths of the two opposing metal lines are substantially the same as the length of the center electrode.
Since the two spacers are arranged on the edge of the center electrode in a circumferential diagonal direction, only two spacers are used, and the other points are the same as those of FIG. Further, the spacer shown in FIG. 5 can be applied by a method substantially similar to the method of arranging the spacer of FIG.

  FIG. 6 shows a spacer different from the above of the present invention, and a plane viewed from one of the counter electrodes and the side surface of the center electrode when the spacer is disposed between the electrodes. The spacer here can be said to be the spacer shown in FIG. 3 in which the lengths of the two opposing metal lines are substantially the same as the length of the center electrode. Since these two spacers are arranged on the edge of the center electrode in the diagonal direction, only two spacers are used. Otherwise, the spacer is the same as the spacer of FIG. 3, and the spacer of FIG. It can be applied in the same way as in FIG.

FIG. 7 shows a spacer different from the above of the present invention, and a plane viewed from one of the counter electrodes and the side surface of the center electrode when the spacer is disposed between the electrodes.

Although not shown in FIG. 7, as a spacer similar to the spacer of FIG. 7, an arbitrary number of substantially U-shaped forms and substantially L-shaped forms or inverted L-shaped forms are available. Only spacers combined can be mentioned. Moreover, you may connect the both ends of a spacer so that the side which consists of metal wires may form a fixed angle. Further, the length of the central side of these spacers is not particularly limited. Further, the lengths of the two sides connected to both ends of the central side of the spacer are not particularly limited, and the lengths of the two sides may be the same or different. It is preferable to connect the both ends of the central side and the side connected to the part so as to make a right angle, but in addition, it may be connected so as to be an acute angle or connected so as to be an obtuse angle. You may do it.
The overall size of this spacer is approximately the same length as the applied center electrode, and the width is preferably approximately the same as the circumference of the applied center electrode. For example, the width of the spacer may be shorter than the circumference of the center electrode.
This spacer can also be produced by bending from a single metal wire. As another method, for example, end portions of the same length of metal wire are welded or bonded to both ends of one metal wire, respectively, and the welded material or one of the metal wires of the bonded material is substantially L-shaped. The end of the short side of the metal wire bent into a substantially L shape is welded or bonded to the end of the short side of the metal wire bent into a shape, and then the end of the long side of the metal wire bent into a substantially L shape The spacer shown in FIG. 7 can also be manufactured by welding or adhering and repeating the same welding operation thereafter. The material and thickness of the metal wire used are almost the same as in FIG.
The method of arranging the spacer on the center electrode is not limited in any way. There is a method in which the spacer is arranged by being hooked on the other arc portion of the electrode. When this spacer is disposed on the center electrode, one spacer or a plurality of spacers may be used. The number is appropriately changed depending on the conditions under which the ozone generating tube is used. That is, it can be changed depending on whether the installation site of the ozone generating tube is subjected to vibration, whether the ozone generating tube is placed vertically or horizontally.

FIG. 8 shows a spacer different from the above of the present invention, and a plane viewed from one of the counter electrodes and the side surface of the center electrode when the spacer is disposed between the electrodes.

The method of arranging the spacer on the center electrode is not limited at all, but for example, the central side on one side of the spacer is hooked on one chord portion of the central electrode, and then the central side on the other side of the spacer is set. There is a method of placing the spacer by hooking on the other string portion of the center electrode, and the gap length between the center electrode and the ground electrode can be accurately maintained by a simple operation.
