Short description of the organization (max 12 lines): -
Expertise offered At present time there are different ways and constructions of plants for ozone getting, including the most perspective ozone generators which use the electromagnetic field of high frequency (HF (high-frequency)-ozonizer).
But the known ways and plants, including HF-ozonizers, cannot always provide the sufficient output of ozone in case when it is necessary to get a great deal of it.
The aim of the project is to accomplish a task of increasing the ozone output (kg and dozens of kg), to simplify the construction of the ozonizer and to reduce the price of it, to miniaturize its size and to reduce power inputs, this will make it possible to bring down the price of ozone and to diminish the production space.
This problem is suggested to be solved on the base of 2 patents of the Russian Federation ( 1) Kamyshanchenko N.V., Mahanjkov G.V., Ryzhkov I.V., Taran A.V., Chekanov N.A. Ozonizer. The patent of the Russian Federation № 2178383, C 01 B 13/11, 2002; 2) Ryzhkov I.V., Taran A.V., Chekanov N.A., Shvetz O.M. Jet high-frequency ozonizer).
The patent of the Russian Federation № 2259939, C 01 B 13/10, 2005), in which 2 principal problems of the increase of ozone output are solved:
  • to divide in space the zones of dissociation (about 3000 K) of molecular oxygen and synthesis of ozone (O2 + O – O3) to make each of these processes pass under the temperatures optimal for it, that increase the ozone output;
  • to apply the supersonic nozzle of Laval which let pass the big volume of oxygen-containing gas that also will increase the ozone output.
By this construction of the ozonizer the power inputs, for example, for getting 1 kg of ozone will be about 0.9 kvh (the existing ozonizers make it 5-20 kvh/kg O3). This economy is determined by the fact that in the suggested ozonizer the gas is heated only in the zone of dissociation that makes only 3-4% of all consumable gas.
Simultaneously the output of ozone increases and the size, material capacity and steel intensity of all plant reduce.
These ozonizers are necessary for: 1) ozone treatment of water in big volumes, for example, on a city scale; 2) when ecocatastrophes (for example, when the atmospheric injection of harmful substances takes place); 3) etching of sowing corn, in the industry.
Prospective results:
  1. Making, at least, experimental model, measuring its parameters on the test desk;
  2. Conducting the researches together with the biologists, chemists, ecologists for the purpose of extermination of germs and harmful substances;
  3. Bringing the parameters of the ozonizer to the demanded characteristic and making the experimental model for the industrial production;
  4. Concession rights to intellectual property.
