Description

The utility model relates to poultry farming, in particular to systems for purification and ozonation of recirculated air in livestock and poultry facilities.

A device for air ozonation (RU 2109221, IPC F24F 3/16, 04/20/1998, Bull. No. 11), consisting of a chamber with electrodes connected to a high voltage source, parallel to each other and installed in the centers and vertices of regular polygons, is known forming a regular structure.

The disadvantages of this device are: 1 - increased consumption of electrical energy; 2 - air purification is not performed.

Closest to the claimed technical solution, taken as a prototype, is an electrostatic precipitator with increased ozone generation (S. Taimanov. Research and development of an electric air purification system and egg disinfection in an incubator. Abstract of dissertation ... Ph.D. - Chelyabinsk, CHIMESKH. 1995. 23 p.), Consisting of a housing with a fan blowing air through a system of corona and precipitation electrodes "a series of wires between planes", powered by a high voltage source.

The disadvantages of this device are: 1 - low efficiency of air purification; 2 - such geometric parameters as the interelectrode distance and the distance between the corona electrodes are not justified.

The purpose of the invention is to increase the efficiency and reduce energy costs of technological processes of livestock and poultry complexes due to the highly efficient purification of recirculated air and its simultaneous saturation with ozone.

This goal is achieved in that in order to achieve highly efficient purification of recirculation air and its saturation with ozone in an ozonizer electrostatic precipitator, consisting of a housing with a fan installed in the end of the housing, blowing air through a system of corona wire electrodes receiving a negative potential from a high voltage source, located between grounded precipitation electrodes and representing rectangular metal plates, the interelectrode distance is 2 6-28 mm and the distance between the corona electrodes is 43-45 mm. These parameters directly affect the efficiency of the electrostatic precipitator-ozonizer and its overall dimensions.

When the distance between the corona electrodes is less than 43 mm, with a constant volume, the initial corona discharge voltage increases due to mutual screening. Due to the action of this factor, the corona current, and, accordingly, the efficiency of the electrostatic precipitator-ozonizer, decreases.

With a distance between the corona electrodes of more than 45 mm, the specific volume current decreases, which leads to an unreasonable increase in the overall dimensions of the electrostatic precipitator.

Analysis of the results of the studies showed that with an increase in the number of electrodes and, accordingly, with a decrease

the distance between the corona electrodes, the dynamics of increasing current and power gradually slows down and with a distance between the corona electrodes of 43-45 mm, the current and power values reach their maximum values, a further decrease in the distance between the corona electrodes leads to a decrease in these indicators, which is explained by the mutual screening between the corona electrodes .

The magnitude of the interelectrode distance affects the reliability and efficiency of the electrostatic precipitator-ozonator. When the interelectrode distance is less than 26 mm, the reliability of the electrostatic precipitator-ozonizer decreases, and the risk of breakdown increases. When the interelectrode distance is more than 28 mm, the efficiency of the electrostatic precipitator-ozonizer decreases. The range of 26-28 mm is rational in terms of the ratio of reliability and efficiency of the electrostatic precipitator-ozonator.

As a result of checking the patent search in the patent and scientific and technical literature, the authors did not find an identical technical solution, which allows us to conclude that the claimed technical solution meets the criterion of "novelty."

The figure shows the design of an ozonizer electrostatic precipitator, consisting of a housing 1 with a fan 2 installed in the end part of the housing, blowing air through a system of corona wire electrodes 3 receiving a negative potential from a high voltage source 5 and located between the grounded precipitation electrodes 4.

The device operates as follows.

The action of this electrostatic precipitator is based on a corona discharge. Purified air passing between the corona and precipitation electrodes enters the field

corona discharge, in the outer region of which there are negative ions that create a unipolar space charge in the interelectrode space. If solid or liquid particles are located in the outer region of the corona discharge, which occupies the predominant part of the interelectrode space, then ions from the space charge deposited on the surface of these particles inform them of an excess electric charge, that is, the particles are charged. Further, under the influence of electric field forces, charged particles move in a direction perpendicular to the flow and are deposited on the precipitation electrodes, as a result of which dust particles and microorganisms are removed from the cleaned air. In turn, the ozone generated by the corona discharge oxidizes the harmful gas components and various microorganisms. Further, the air purified from dust, microorganisms and harmful components is supplied to the livestock building.

The use of this electrostatic precipitator-ozonizer increases the efficiency and reduces the energy consumption of technological processes of livestock and poultry complexes due to the highly efficient purification of recirculated air and its simultaneous saturation with ozone.
