Abstract

The invention relates to methods for producing ozone used in chemical technology, and improves the efficiency of the ozone synthesis process. When ozone is produced from an oxygen-containing gas, a dispersed catalyst is introduced into the volume of the discharge gap by electric discharge and fluidized with jets of oxygen-containing gas, the volume of the fluidized bed not exceeding one third of the discharge gap volume. 1 hp f-ly, 1 ill.

Description

The invention relates to inorganic chemistry, in particular, to methods for producing ozone by electric discharge.

The purpose of the invention is to increase the efficiency of the ozone synthesis process.

The drawing shows a diagram of the device with which the proposed method is carried out.

The device contains a chamber 1 in which two electrodes 2 and 3 are mounted. These electrodes form a discharge gap. Moreover, the upper electrode is provided with tips for forming a corona discharge. The electrodes are isolated from the chamber by a dielectric pad 4. A high-voltage power supply 5 is connected to the electrodes. Air is pumped into the chamber and 6. Dispersed catalyst 7 is introduced into the volume of gas discharge between two electrodes 2 and 3. Pump 6 pumps oxygen-containing gas into the chamber.

Power supply voltage 5. is supplied to electrodes 2 and 3. At the same time, pump 6 supplies oxygen-containing gas to the chamber. Through the holes of the lower electrode 2, the gas enters, the volume of the gas discharge. The ascending gas jets, passing through the orifices of the lower electrode 2, are turbulized and the dispersed catalyst is distributed over the volume of the gas discharge, so that a fluidized bed is formed above the electrode 2. Since the surface of such a catalytic layer is large, there is an increase in the efficiency of the ozone synthesis process. An increase in the fluidized bed volume of more than one-third of the volume of the discharge gap leads to a destabilization of the electrical discharge in the volume and to a deterioration of the conditions for ozone synthesis.

The advantage of the proposed method

Ozone radiation also consists in toM, which makes it possible to use sufficiently wide discharge intervals, which makes it possible to avoid preliminary air preparation (cooling, dedusting, drying). The use of atmospheric air without preparation only slightly reduces the output of the fzone prn using the proposed tool. The use of a dispersed cahalizer increases the efficiency of the pro ii (ecca electrosynthesis by creating an advanced catalytic surface

and allows to obtain in this example a concentration of 12 mg / l at the exit of the ozonizer. The choice of an appropriate catalyst can be achieved and large concentrations at the same energy consumption.
