Description

The invention relates to a device for producing ozone from air and can be widely used in various fields of technology and the national economy for deodorizing or sterilizing indoor air, local ozonation of air in hard-to-reach volumes, vegetable stores during storage or preservation of vegetables and fruits, for sterilization, treatment of wounds in medicine, to stimulate the spring development of bee colonies and the prevention and treatment of bee diseases, etc.

A small-sized ozonizer is known (RF patent No. 2063928, IPC 6, С01В 13/11, publ. 1994), containing a cylindrical coaxially located and connected to a power source external electrode made in the form of a housing made of conductive material whose ends are closed by flanges, and an internal electrode made of sheet brass coated with nickel or chromium. Small ozonizer made in accordance with this invention is characterized by the complexity of the design and its high cost.

A known ozonizer (USSR author's certificate No. 1121232, IPC 6, C01B 13/10; C5D 27/00, publ. 1983), containing an ozone generator, a high voltage transformer connected by its secondary windings to the ozone generator electrodes, an autotransformer with controlled yokes, including interconnected voltage stabilization unit and a comparison unit. With acceptable reliability, such an ozonizer has large dimensions and weight.

Closest to the proposed invention is an ozonizer (RF patent No. 2132300, class СВВ 13/11, 06/27/99), containing in an ozone-resistant casing a high voltage power source and a discharge device made in the form of metal plates coated with a dielectric and dielectric plates, which from the side of the discharge gap have a metal coating coated with a dielectric.

The ozonizer selected as a prototype has significant drawbacks, in particular, the complexity of the design, low productivity and reliability.

The technical solution to the problem is to increase the efficiency, reduce the level of energy consumption and overall dimensions, provide the possibility of local ozonation of air in hard-to-reach volumes, and increase reliability.

.This object is achieved in that the electric shielding device comprising a power supply unit in an ozone-resistant common housing, a high voltage power supply according to the invention is equipped with a plate-type discharge device with a double-sided arrangement of rectangular aluminum electrodes with rounded edges, which is placed in a sealed enclosure connected by a flexible ozone-resistant duct with a piston micro-compressor, which is connected to the output of the power supply, while the radius of the rounded edge of the electrode R and voltage e U supplied to the discharge device taken in the ratio

.

The technical result is the creation of an ozonizer with a higher efficiency of ozone generation, lower energy consumption, allowing for local ozonation of air in hard-to-reach volumes.

, что позволяет избежать высокой напряженности электрического поля у краев электродов и предотвратить преждевременный пробой диэлектрического барьера.The novelty of the invention lies in the fact that the electrodes are made of aluminum, rectangular in shape with rounded edges, and the radius of rounding of the edge of the electrode R and the voltage U supplied to the discharge device are taken in the ratio

This avoids the high electric field at the edges of the electrodes and prevents premature breakdown of the dielectric barrier.

The proposed technical solution is illustrated by drawings, where figure 1 shows the electrode, figure 2 is a diagram of the electric gap.

.The electric shielding device comprises a housing 1, in which a piston micro-compressor 2 is placed, connected to the input pipe 3 and connected to the output of the power supply 4, to which the operating mode control unit 5 is connected, connected to the high voltage power supply 6, which is connected to the discharge device placed in a sealed housing 7 connected to the outlet pipe 8 and the piston micro-compressor 2 through a flexible ozone-resistant air duct 9, and consisting of rectangular dielectric plates of glass 10, rectangular aluminum electrodes 11 with rounded corners, and the radius of the fillet corners of the electrodes and the voltage supplied to the discharge device are taken in the ratio

.

A small-sized electrozonator works as follows: the supply voltage is supplied through the operating mode control unit 5 to the piston micro-compressor 2 and the power supply 4, as a result of which the air mixture is sucked by the piston micro-compressor 2 through the flexible inlet pipe 3 and then through the ozone-resistant duct 9 enters the sealed housing 7 of the discharge device . From the terminals of the power supply unit 4, the voltage of the specified parameters is supplied to the high voltage power supply 6, from the terminals of which the voltage is supplied to the electrodes of the discharge device 11, as a result of which a barrier type discharge appears in the discharge gap, in which ozone is generated, which means that an ozone-air mixture is formed, which through the outlet pipe 8 is fed into the required hard-to-reach volumes.
