Abstract

PURPOSE:To prevent deposition of carbon powder on an electrode of the titled apparatus, by attaching insulation plates at both ends of a stationary electrode, providing an electrode plate and a blade to a rotary electrode, rotating the electrode plate and the blade together with the rotary electrode and sucking air through the insulation plate. CONSTITUTION:A bearing 3 is fixed to the center of insulation plates 2 attached to both ends of a cylindrical stationary electrode 1 and a rotary electrode 4 is supported by the bearing. A plurality of electrode plates 5 and air blower blades 5' are attached to the rotary electrode 4 and rotated together with the electrode to suck air through an inlet port 10 of the insulation plate 2 into the stationary electrode 1. Corona discharge is generated between the stationary electrode 1 and the electrode plate 5 by applying electrical potential from a high-frequency high-voltage power source 9. Air sucked in the stationary electrode 1 is ionized to convert a part of oxygen to ozone, which is instantaneously decomposed into an oxygen molecule and an oxygen atom and discharged through an outlet 11 of the other insulation plate 2'. The deposition of suspension carbon to each electrode can be prevented by the air stream.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improved structure of an ion generator using plasma discharge or the like.

[Conventional technology and problems] Many ion generators of this type have been known in the past.
For example, as seen in Japanese Utility Model Publication No. 59-32858, these have a structure in which both the anode side electrode and the corresponding cathode side electrode are fixed,
During use, powdered carbon adheres to and covers the electrodes due to abnormal discharge, etc., which has the disadvantage of significantly reducing the amount of ozone generated.

[Purpose of the Invention] The present invention aims to provide an improved ion generator that does not allow carbon powder to adhere to the electrodes even after long-term use, and therefore does not reduce the amount of ozone generated over time. This is the purpose.

[Structure of the invention] Insulating plates are attached to both ends of a cylindrical fixed electrode, and both ends of a rotating electrode are rotatably pivoted at the center of each insulating plate, and a plurality of electrode plates and blower blades are attached to the rotating electrode. established,
Further, one insulating plate is provided with an air inlet, and the other insulating plate is provided with an air outlet.

[Production ■] The fixed electrode is used as an anode and the rotating electrode is used as a cathode to connect to a high-frequency, high-voltage power source, and by rotating the once-rotating electrode, the blower blades are rotated together with the once-rotating electrode, and air is taken into the fixed electrode from the suction port. , the air is ionized by the electric field in the discharge,
Some of the oxygen is converted to ozone, which is immediately decomposed into oxygen and oxygen atoms and sent out through the outlet.

[In the figure of the embodiment, 1 is a cylindrical fixed electrode, with insulating plates 2, 2' attached to both ends, and these insulating plates 2, 2'
Bearings 3, 3 made of ball bearings are fixedly installed in the center.

Reference numeral 4 denotes a rotating electrode in the form of a linear shaft, and both ends of the electrode 4 are pivoted around bearings 3.degree. 3, and are rotatably disposed within the fixed electrode 1. A plurality of electrode plates 5 and air blowing blades 5' which are electrically connected to the rotating electrode 4 are fixedly installed in the central part of the rotating electrode 4 facing into the fixed electrode 1,
A rotating shaft 8 of a motor 7 is connected to one end via a coupling 6.

As shown in FIG. 3, the electrode plate 5 is formed by providing a large number of through holes in a circular plate with a zigzag wave shape around the periphery.

Reference numeral 9 denotes a high frequency high voltage power source, the anode of which is connected to the fixed electrode 1, and the cathode connected to the rotating electrode 4.

Further, one insulating plate 2 is provided with a plurality of air inlets 10, and the other insulating plate 2' is provided with a plurality of air outlets 11.

Next, the operation of the ion generator of the present invention constructed as described above will be explained.

The rotating electrode 4 is rotated by the drive of the motor 7, and the air blowing blades 5' are rotated together with the electrode plate 5, so that air is sucked into the fixed electrode 1 through the inlet 10 provided in the insulating plate 2.

With air flowing in the direction of the arrow, the electrode plates 5 of the fixed electrode 1 and the rotating electrode 4 are
A uniform corona discharge is generated in between.

The air sucked into the fixed electrode 1 from the inlet 10 is ionized by the electric field during discharge.

A part of the oxygen changes into ozone, and this ozone is immediately decomposed into oxygen and oxygen atoms, which are sent out from the outlet 11 provided in the other insulating plate 2'.

When used in this way, the rotating electrode 4 on the cathode side continues to rotate, and the blowing blades 5' fixed to the rotating electrode 4 create an air flow in the electric field during discharge. This reduces the heat generated by corona discharge and prevents floating carbon from adhering to the electrodes, making it possible to continue generating a constant amount of ozone without reducing the amount of ozone generated.

Further, FIG. 4 shows an embodiment in which five air blowing blades 5' are formed in the shape of a propeller. In this embodiment, the air flowing in from the inlet 10 is stirred by each blade 5a tilted at a required angle, and wind pressure can be generated, thereby strengthening the air flow and increasing the amount of air sent to the outlet 11. can be increased.

[Effects of the Invention] As described above, the ion generator of the present invention continuously supplies sufficient oxygen by constantly flowing air into the electric field by rotating the electrode plate attached to the rotating electrode and the blower blades. I can do it. In addition, by creating an air flow between the fixed electrode and the rotating electrode, it is possible to cool down the heat generated due to discharge, thereby preventing carbon from adhering to the ffi electrode. This allows a constant amount of ozone to be continuously generated for a long period of time without reducing the amount of ozone generated.
