SUBSTANCE: air ozoniser comprises an ozonising chamber 1 in the form of a rectangular prism made completely of insulating material, a high-voltage nanosecond pulsed power supply operating in periodic pulse mode with a potential lead 2, having a negative polarity, and an earthed lead 3. The chamber 1 has, inside it and arranged in parallel, a section 4 for a potential electrode and a section 5 for a non-potential electrode, having the same number of parallel current-conducting plates 6 and 7. The sections 4 and 5 are mounted in the chamber 1 such that the planes of each of the potential plates 6 coincide with the plane of the corresponding non-potential plate 7 and with the direction of air flow in the air duct. Thus, an "edge-edge" geometric electrode system is formed with electrode spacing 8, the length of which is equal to the length of the plates 6 and 7.
EFFECT: invention improves synthesis and output of ozone owing to high concentration of electrons in the discharge gap of the ozonising chamber of the apparatus.
The invention relates to a device for ozonation of air and can be used to clean the air of harmful gases and micro-organisms, water purification and water treatment, but also as a source of radicals or other reactive species in low-temperature plasma generators.
A device for ozonation of air (USSR author's certificate No. 1543193, CL F24F 3/16, C01B 13/11, Appl. 13.10.87, publ. 15.02.90), containing situated in the ozonized air duct chamber with needle electrodes connected to the high voltage source and directed edges towards each other. Between the electrodes there is a metal diaphragm that is connected to the negative pole of the source. The electrodes are arranged symmetrically with respect to the diaphragm and is connected to the positive pole of the source. The disadvantage of this device is the low yield of ozone due to the low density of charge carriers electron-ion plasma in the streamer corona discharge, which is formed in the ozonized camera with needle electrodes connected to the DC high voltage.
A device for generating ozone (patent RF №2211800, IPC C01B 13/11, Appl. 29.11.2001, publ. 10.09.2003) containing the high voltage pulse generator and the connected working chamber with electric�ne system in the form of coaxial external low-voltage tubular electrode and the inner high voltage electrode in the form of a conductive rod, which in planes perpendicular to its longitudinal axis, installed additional conductive plate. In addition, between the high voltage pulse generator and the working chamber a high-voltage switch. The disadvantage of this device is the low yield of ozone by pulsed corona discharge, which is formed in the working chamber with the electrode system.
The closest to the claimed is a device for ozonation of air (patent RF №2176366, IPC F24F 3/16, C01B 13/11, Appl. 10.04.2000 from G., publ. 27.11.2001 g) containing ozonized camera with needle electrodes connected to a source of high-voltage nanosecond high voltage with positive polarity. Ozonised chamber made in the form of a prism, with one pair of opposite faces are made of metal and connected to the grounded terminal of the high-voltage nanosecond pulsed power source, the other pair of faces is made of a dielectric, and in the plane of symmetry between the grounded edges is a needle electrode connected to the high voltage output of the power source. The disadvantage of this device is the low yield of ozone due to the low concentration of charge carriers in the discharge gap during nanosecond pulsed corona discharge, which is formed in ozonised �Amer with needle electrodes.
The object of the invention is to increase the productivity of the device for ozonization of air. The technical result of the invention is the intensification of the discharge process due to the homogeneous volume pulsed corona discharge and increase the concentration of charge carriers, electron-ion plasma, i.e., by increasing the concentration of electrons in the discharge gap ozonised the camera device.
The problem is solved in that the device for ozonization of air containing located in the duct ozonised camera, made in the form of a rectangular prism, in which there are potential and non-potential electrodes connected to the terminals of high-voltage nanosecond pulsed power source, prism ozonised camera made entirely of insulating material, the potential output of the power source has a negative polarity, in addition, the potential and nonpotential the electrodes are in the form of parallel sections, consisting of an equal number of parallel conductive plates that form a geometric system of electrodes "edge-edge", and the planes of each potential and the corresponding non-potential plate coincide with each other and the direction of the air flow in the duct�.
It is known that to increase the intensity pulsed corona requires the creation of a strong surge in air gap due to the creation of a high voltage pulse with a sharply rising leading edge. In this case, the mode ultramarine nothing, because the discharge is immediately developed in the form of streamers, and the transition to the streamer mode in spark and contracted glow discharge is eliminated by limiting the pulse duration of the applied voltage (Yu. s. Akishev, the data processing machine G. I., M. E. Grushin, etc. / / plasma Physics reports, 2008, vol. 34, No. 4, pp. 347-360). It is also known that the greatest density of charge carriers, electron-ion plasma is achieved in the discharge gap during its three-dimensional shape of the discharge (Baranov V.., Borisov V. M., Stepanov Y. Y. electric-Discharge excimer lasers halides of inert gases. - M.: Energoatomizdat, 1988. - 216 (C).
In the proposed device the fulfillment of potential and non-potential electrodes in the form of parallel sections parallel plates which form a geometric system of electrodes "edge-edge" with strongly nonuniform electric field, and ozonized camera completely of insulating material provides, when using the power source with a negative polarity, and the formation of uniform volumetric pulse-periodic nanosecond to�discriminatory discharge in air flow atmospheric pressure of natural moisture, that leads to an intensification of the discharge process, i.e. to the increase of discharge current, and hence to an increase in the concentration of electrons in the discharge gap, which play the most important role of all charged particles present in the discharge. This is because the electrons have the highest energy and can cause the following processes: dissociative attachment of an electron to a molecule of oxygen to form ozone; the excitation of electronic levels with subsequent dissociation of a molecule of oxygen to form ozone; the collision of excited nitrogen molecules with a molecule of oxygen to form ozone; dissociative electron-ion recombination with the formation of ozone. Thus, intensification bit process causes an increase of ozone synthesis and its output.
The invention is illustrated by drawings, which schematically shows a device for ozonation of air in two projections.
A device for ozonation of air contains ozonized chamber 1 made in the form of a rectangular prism entirely of insulating material, a high-voltage nanosecond pulsed power source operating in a pulsed-periodic mode, with potential output 2 having a negative polarity, and grounding pin 3. Inside the chamber 1 is placed parallel�located on section 4, the potential of the electrode and the section 5 non-potential electrode, that contain equal numbers of parallel plates 6 and 7 are made of a thin conductive material. Sections 4 and 5 are mounted in the chamber 1 so that the plane of each of the potential of the plates 6 are coincident with the plane of the corresponding non-potential plate 7 and with the direction of the air flow in the duct. Thus, the formed geometric system of electrodes "edge-edge" with interelectrode gap 8, the length of which is equal to the length of the plates 6 and 7. Ozonised camera 1 is not shown in the drawing space of the duct, which allows pumping ozone-air mixture at different flow velocities through the interelectrode gap 8. The total area of sections 4 and 5, as well as the magnitude of the interelectrode gap 8 is determined by the capacity of high-voltage nanosecond pulsed power source.
The device operates as follows.
The air flow enters the duct in ozonised chamber 1 and, respectively, in the interelectrode gap 8. When you turn on high-voltage nanosecond pulsed power source of negative polarity, operating in pulsed mode with an output voltage of ~30 kV, a pulse duration of 20 not at the 0.5 level and slew rate of the electric field of ~2 kV/(cm·HC) in the electrode gap length�nd 0.6 cm, excited by a uniform pulse-periodic nanosecond corona discharge volume of ~220 cm3. The performance of ozone in the speed of air flow ~25 m/s can be adjusted by changing the frequency of the pulse-periodic discharge in the range of 0.05 Hz to 1 kHz.
