Description

The utility model relates to the field of air enrichment with negative ions and ozone and can be used in artificial climates, in particular, for ozonation of air with a controlled content of nitrogen oxides in it.

A device for air ozonation containing a housing is known, inside of which there are ionizing electrodes in the form of needles and a diaphragm in the form of a grid, in the nodes of which are needle electrodes (see AC No. 1726918 IPC F24F3 / 16)

The disadvantage is the design complexity and the need for injection devices, as well as the lack of regulation of ion concentration.

A device for air ozonation is also known, including a housing, a diaphragm and two ionizing needle electrodes located on both sides of the diaphragm and connected to different poles of the high voltage source. (See AC No. 1283498 IPC F24F3 / 16).

This device has a simpler design, but it limits the performance of ions due to the limited range of corona discharge.

Closest to the proposed one is a device containing an ozonizing chamber located in the duct with needle electrodes connected to a high voltage source and directed tips towards each other, and a metal diaphragm located between the electrodes. The device additionally contains metal gratings with electrodes placed on them, while the metal diaphragm is made in the form of a grid and connected to the negative polarity, and the needle electrodes are located symmetrically to the diaphragm and connected to the positive polarity of the high voltage source (see AC No. 1543193 IPC F24F3 / 16 )

The implementation of ozonizing electrodes in the form of needles is time-consuming and non-technological, the performance of the ions is unregulated and an additional pumping device is required to remove ions from the ionizing space of the body. The concentration of nitrogen oxides in the mixture cannot be regulated, and the reliability of operation is low, since the ionizing electrodes and the diaphragm are connected directly to the high voltage source and, in the event of breakdown of the gaps, the diaphragm and the housing-zoned electrodes decrease the operational safety.

MPKR24RZ / 16 OZONATOR

The objective of the utility model is to simplify the design and technology to increase the performance of oxygen ions while reducing the concentration of nitrogen oxides and increase the reliability and safety of operation of the device.

An ozonizer containing ionizing electrodes connected to a high voltage source and conductive grid diaphragms located in the housing, according to the solution, further comprises a dielectric diaphragm, the ionizing electrodes being made in the form of two symmetrical zigzag conductors with a diameter of 0.05-0.25 mm located in parallel planes at a distance of 300-100 diameters of the conductors from each other, with a dielectric diaphragm located between them, the slots of which are parallel to the zigzag conductors and located between them, and on the opposite sides of the ionizing electrodes at distances of 100-300 diameters of the ionizing conductors in the planes parallel to the planes of the ionizing electrodes are conductive diaphragms with slots perpendicular to the zigzags of the ionizing conductors, one of the zigzag ionizing electrodes being connected through the high-resistance resistor to the positive pole of the source voltage, and the other also through a high-resistance resistor - to the negative pole.

The slots of the dielectric and conductive diaphragms make up 0.4-0.6 of the spatial period of the zigzags of ionizing conductors.

In the walls of the housing there are openings for the flow of air into the ionizing space.

The high voltage source contains a rectifying element, a thyristor, a quenching resistor, a charging circuit consisting of a resistor and a capacitor, forming together a shock excitation circuit, raising a pulse transformer and a voltage multiplier, and the quenching resistor is made in the form of an incandescent lamp located on the outside of the source, and charge circuit resistor adjustable.

Ionizing electrodes can be connected to either one pole of a high voltage voltage source, or to different ones, depending on the performance of nitrogen and negative ions.

The ozonizer of air (gases) consists of a high-voltage power supply 1, high voltage leads 2, ionizing electrodes 3, conductors of diameters 0.05-0.25 mm, arranged in a zigzag manner on insulators 4 in parallel planes at a distance of 300-100 diameters of ionizing conductors from friend. Between them in a parallel plane there is a dielectric diaphragm 5 with slots (a group of holes) parallel to the ionizing conductors and located between the zigzags. On both sides of the ionizing electrodes 3 at a distance of 100-300 diameters of the ionizing electrodes and in planes parallel to them are conductive (slotted) diaphragms 6 with slots perpendicular to the zigzags, so that between the ionizing electrodes 3 and

iO & tUI

the diaphragm 6 is formed periodically located region 1 of increased electric field strength.

The high-voltage source 1 of the bipolar voltage consists of a rectifier device 9, a thyristor 10, a variable resistor 11, a capacitor 12, a primary winding of a high-voltage pulse transformer 13 and a quenching resistance 14, forming a shock excitation circuit, a voltage multiplier 15, and high resistance (1.5-2 MΩ) resistors 16, including high voltage leads 2 in contact with ionizing electrodes 3.

The ozonizer works as follows:

A high voltage of 25-30 kV is generated from an alternating voltage network of 220V, 50Hz (or another source using a rectifier device 9, a thyristor 10, a charging circuit 11.12, a shock excitation circuit consisting of a capacitor 12, a primary winding of a high-voltage transformer 13, and a quenching resistor 14. The resulting high voltage is increased to the required value using the multiplier 15 and through high-resistance resistors 16, in order to ensure safe operation and prevent the corona discharge from turning into a spark, it is fed to the ionizer Suitable electrodes are either symmetrically or asymmetrically, i.e., ionizing electrodes may either be connected to different poles of the source or to one of them, and wherein the other pole is connected to the body 7 of the ozonator.

In any combination, the distance between the planes of arrangement of the ionizing electrodes is less than that between the last and the conducting diaphragms 6. Initially, the corona discharge develops in all directions, but charges on the both sides of the dielectric diaphragm 5 are created in the same polarity as the ionizing electrodes, therefore, a predominant discharge forms in side of the conductive diaphragms 6, since the discharge is localized in areas 17 of increased electric field strength and these areas 17 are equivalent to the same needle arrangement ionizing electrodes. When the ionizing electrodes are connected in different polarity, a larger amount of ozone and, accordingly, ions are created with a positive corona, therefore, an advantageous transfer of ions of both signs in the direction from the negative ionizing zigzag electrode to the positive one, i.e. the process of “pumping air with neutral oxygen molecules through the side openings of the housing 7 and from the side of the negative ionizing electrode 3 is carried out and converting them into ions during passage of the ionizing space. When unipolar connection of ionizing electrodes 3, as a result of action

charges on the surface of the dielectric diaphragm, the generated ions of the corresponding sign move in different directions, and the necessary air pressure gradient is created due to holes in the side walls of the ozonizer body 7 and convection flow due to the action of the quenching resistor 14.

The quality of the mixture of various ions in the air is adjusted by changing the high voltage using a resistor 11. The nitrogen ionization potential is higher than the oxygen ionization potential, so it is possible to create the optimal concentration of negative ions in the air due to this adjustment.
