Abstract
The present invention relates to devices for producing ozone, wherein said devices use a pulsed corona discharge such that there is no need for a dielectric in the electrode gap. This invention may be used to increase the ozone concentration above 20 g/standard m3 (a concentration required for the practical use of an ozonator), while reducing the power consumption necessary for producing ozone down to 10 kW-hr/kg of ozone in an ozonator that uses such pulsed corona discharge. In order to achieve such results, this invention proposes an ozonator for producing ozone in a pulsed corona discharge, wherein said discharge is ignited by sending short pulses (less than 500 nanosec.) having a high voltage and a positive polarity onto a corona-generating electrode. The electrode not generating a corona or at least the part thereof which is in contact with said discharge is made of aluminium, an aluminium alloy or a conductive alloy having a thermal conductivity exceeding 50 W/m*degree. The high-voltage pulse source is provided with a high-voltage on/off function and generates a pulsed corona discharge having a specific power exceeding 50 W/l. The frequency between successive pulses is higher than 500 Hz, while the ratio between the amplitude of the high-voltage pulses and the amplitude of the remaining DC voltage between said pulses is 1.5-3.

This is due to various mechanisms of destruction of the zone. Аз Non-standard ZONE may die in a gas chamber or at a standstill of a single chamber. In the first case, the energy price of the product is increased (with the constant concentration of the product) with an increase in the specific fixed energy consumption of the gas.

As a result, in order to achieve a high concentration of gas, the gas storage time in the secondary chamber should be comparable to the case of a large discharge. Otherwise, a large non-discharging medium interferes with the manifestation of an efficient inactive gas stirring in a different zone. This mixing significantly increases the transfer of heat and particles to the wall of the dis- charge camera in comparison with the diffuse transfer.

This is a positive effect, t.κ. In spite of a large dis- charge, there is no gas inter- Β The pulse circuit does not have a maximum gas temperature that rises above the temperature of the discharge chamber at a temperature of 15 ° С. There is a slight difference in the size of this bar a little. However, a larger amount of time spent in the disposable camera and on-line stirring of gas results in a loss of life on the wall of the disposable chamber. With an increase in the average specific power of the pulsed discharge and a decrease in the time of gas generation in the discharged chamber, the energy cost of the gas decreases. The impairment of the disconnection of the transmitter at the speed of the discharged camcorder impulses of a large dis- charge in the environment is in the form of electricity Apparently, the disintegration of the consumable is in the main process in the "hot spheres", which is in the process of discharging the charge These “hot points” are reminded of several spots in an arc discharge and have an elevated temperature.

It works with the following. The source of continuous voltage supports voltage at a working voltage of 70 kK. At the moment of the pulse, the generator generates the suppressing signals that form a voltage pulse on the network, which turns off the lamp for the duration of the compensating signal. When this happens, the electrical impulse of the power supply is pulsed by a positive impulse of an amperage of 60 kp, which ignites an impulse of a short circuit The duration of the off-grid network pulses is selected no more than the development of a short-circuit discharge in a gaseous interconnection. The repetition rate of high-frequency pulses of more than 1000 Hz, duration of 200 ns. After the lamp is turned on, the residual voltage of the battery discharges the capacity of the battery with a maximum voltage to the maximum voltage. The recorded characteristics of the vacuum lamps and the parameters of the source of the pulses made it possible to achieve the capacity of the base for the capacity of the carrier for 50 As a result, the product obtained is obtained at a rate of 2.0 kg / h, the cost is lower than 20 g / nm 3 and an average cost of 10 * is obtained. 6 The possibility of using an electronic pulse generator is not limited by the variant of the discharge chamber and the source of voltage. Alternatively, use vacuum lamps with other parameters (analog voltage, normal current, switched capacitance, etc.).
