Description

The invention relates to plasmochemistry and can be used in areas of the national economy where ozone is needed.

A quiet discharger for generating ozone is known, comprising two electrodes connected to an alternating current source 1. One electrode is made in the form of two coaxial cylindrical discharges made perforated. The second electrode is made in the form of an insulated wire and wound spirally on the inner cylinder

The ozonizer is a compact design, however, the difficulties associated with blowing large volumes of air between the cylinders make the process less efficient, with high energy costs.

Closest to the proposed one is an ozonizer operating on the principle of using corona discharge 2. This ozonizer (one of its variants) contains a plastic pipe and a pair of conductors, each of which has its own plastic insulating coating. Gas passes through the pipeline through the gap left by the conductors and their insulating coatings. Thus, when a high voltage is applied to the conductors, a corona discharge is excited inside the conduit.

The ozonizer is simple in design and its performance is higher than similar options considered in the patent. However, its circuit implementation provides for the connection of a conductor to a single-phase power supply. It is with |

there are a number of disadvantages that cause low productivity: firstly, the use of one phase alone limits the capabilities of the ozonizer, and secondly, the working volume of the chamber (pipe) is used poorly, since the length of the surface discharge is determined by the external dimensions of the two conductors.

The aim of the invention is to increase the ozonizer productivity and ozone concentration by ensuring the efficient use of the internal volume of the pipeline. Structurally, this is realized by the fact that in a known ozonizer containing a pipeline and a pair of electrodes placed therein, a third electrode is additionally installed. At the same time, in the pipeline, the electrodes are laid sequentially in layers of at least four, with the formation of a checkerboard grid. A high-voltage three-phase power source is used as a power source. Air is blown through the conduit, with each electrode connected to a separate phase of a three-phase AC source and all electrodes made with an insulating coating, or two electrodes made with an insulating coating, and an additional electrode made in the form of a pipe made of soft metal filled with running water.

To ensure maximum interaction of the purged air with the discharge and ensure effective heat removal, an ozonizer with electrodes filled with running water, connected to the phases of a three-phase power source in a closed circuit of an electric triangle and made in the form of flexible metal tubes coated with an insulating layer, or in the form of conductors located in individual flexible shells.

In FIG. 1 shows a diagram of an ozonizer with electrodes made with an insulating coating; in FIG. 2 is a diagram of an ozonizer with an additional electrode made in the form of a pipe with water; Fig. 3 is a diagram of an ozonizer with electrodes made in the form of flexible tubes with water; figure 4 is a diagram of an ozonizer with electrodes in the form of conductors in a dielectric sheath.

The ozonizer contains a housing made in the form of a square cross-section pipe 1. Inside the pipe 1, three electrodes (conductors) 2,3,4 are laid, each of which has its own insulating coating (Fig. 1). The conductors are connected to phases I, II, III of a three-phase high-voltage power supply 5 (transformer). Inside the pipeline along its length, the conductors are laid in layers in sequential order, with the formation of a checkerboard grating. Thus, three conductors laid in the above order can form at least a four-light (four-layer) lattice. Possible execution of the electrode

4 in the form of a metal pipe through which running water circulates (FIG. 2). Electrodes 2,3 are made in the form of conductors with an insulating coating. A variant is possible in which the electrodes 2,3,4 are made in the form of metal flexible tubes with an individual insulating coating filled with running water and connected to the phases of a three-phase transformer 5 in a closed circuit of an electric triangle (Fig. 3).

The implementation of electrodes in the form of conductors, stretched in a flexible dielectric shell filled with running water, and connected to the phases of a three-phase power supply 5

closed circuit electric triangle (figure 4).

The ozonizer works as follows. When turning on a three-phase transformer

5, a barrier appears along the surface of the dielectric shell of the electrodes 2,3,4

discharge. As a result of its interaction with the air pumped through the pipe 1, ozone is formed, which is carried out by the air stream.

The ozonizer is simple in design and technologically advanced to assemble. It has high productivity and provides a high concentration of ozone, which is due, firstly, to the possibility of efficient generation of a three-phase barrier discharge, successful heat removal and the maximum possible contact of the pumped air with the discharge.
