Description

 The invention relates to barrier discharge devices in an oxygen-containing medium or air and can be used in the industrial production of ozonizers.

A known ozone generator (RF patent 2159735, IPC ⁷ C 01 B 13/11, 11/27/2000.), Containing a cylindrical body, on the axis of which there is a shaft connected to an electric drive, on which movable electrodes are rigidly fixed, containing a sleeve with grooves in which blades made of ozone-resistant material are inserted, fixed electrodes sealed in a dielectric tube filled with a conductive powder are mounted on the housing parallel to the plane of rotation of the movable electrodes.

 The disadvantages of this device are: the complexity of the manufacture of electrodes, as well as a small discharge area in the interelectrode volume, which reduces the efficiency of the device.

 The technical effect is to increase the concentration of ozone in the air mixture.

 The essence of the invention lies in the fact that in the barrier discharge device, consisting of movable electrodes, rigidly fixed to the shaft, and stationary electrodes, the movable disk electrodes are made in the form of an impeller with blades, on both sides sheathed with sheet conductive material having through holes in front of each section impellers, in alternation with disk electrodes, stationary electrodes are located in the form of frames of dielectric material, on the side posts of which there are holes with inserted in them linear electrodes consisting of two half-cylinders interconnected by a jumper with a terminal soldered to it, placed in a dielectric tube sealed at one end, the inner surface of which is covered with a conductive composition, while a sleeve is located between the movable electrodes on the shaft, the length of which is equal to the width fixed electrodes and two equal gaps between the surfaces of the movable and fixed electrodes. The total area of the through holes on the movable disk electrode is equal to the total area of the rectangles formed by the gaps between the linear electrodes on the stationary electrodes. Linear electrodes can be located on the side racks of the frames in both single row, double row and three row versions.

 Figure 1 shows a General view of the device, figure 2 is a side view, figure 3 is a design of a movable disk electrode, figure 4 is a design of a stationary electrode, figure 5 is a design of a linear electrode.

 The device comprises a shaft 1 (Fig. 1), on which disk movable electrodes 2 are rigidly fixed, in alternation with which are fixed electrodes 3 with holes 4 (Fig. 2), into which linear electrodes are inserted 5. Between the movable disk electrodes 2 on the shaft 1 is a sleeve 6, the length of which is equal to the width of the stationary electrodes 3 and two equal gaps between the surfaces of the movable disk 2 and the stationary 3 electrodes. The movable disk electrode 2 (Fig. 3) is made in the form of an impeller 7 with blades on both sides sheathed with sheet conductive material having through holes 8 opposite each section of the impeller 7. The fixed electrode 3 (Fig. 4) is made in the form of a frame 9 of dielectric material , on the side posts 10 of which there are openings 4 with linear electrodes 5 inserted into them, consisting (Fig. 5) of two half-cylinders 11, interconnected by a jumper 12 with a terminal 13 soldered to it, placed in a dielectric sealed from one end a tube 14 whose inner surface is coated with a conductive composition. The total area of the through holes 8 (Fig. 3) on the disk movable electrode 2 is equal to the total area of the rectangles (Fig. 4) formed by the gaps between the linear electrodes 5 on the stationary electrodes 3. The linear electrodes 5 can be located on the side racks 10 of the frames 9 in a single row , two-row and three-row execution.

 The device operates as follows. From the remote control shaft 1 is driven into rotation with a smooth increase in its speed to nominal for the purpose of drying the electrodes. From air injection (compressor, fan), overpressure air is supplied to the discharge zone, then gradually increasing the voltage from zero to a nominal value for 10-15 minutes (until the electrodes are dried), while the barrier discharge device itself is functioning stably. The stability of the barrier discharge at a voltage of 15–20 kV on the electrodes at a distance from the axis of the central row of linear electrodes 5 to the plane of the movable disk electrode 2 (20–25 mm) is achieved by ionizing the mixed air medium of the interelectrode region of the central row of linear electrodes 5, which is further helps to intensify the discharge around the two extreme rows of linear electrodes 5 and the gaps between the surfaces of the movable disk 2 and the stationary 3 electrodes. In this case, the movable disk electrode 2 intensively mixes the ozone-air mixture and removes the heat generated together with this mixture.

 Compared with the known solutions, the proposed design of the barrier discharge device allows to increase the concentration of ozone in the air mixture by increasing the discharge area, the gap between the electrodes.
