Description

AIR IONIZER; - °

The utility model relates to medicine and can be used for medical and health purposes, as well as in veterinary medicine and crop production.

Air ionizers are well known and are widely used mainly in physiotherapy. In particular, devices with needle emitters and accelerating devices are used; they have electrodes connected to sources of constant or pulse voltage 1.2. The disadvantages of these analogues should include the presence of loss of aeroions in contact with accelerating; with an electrode. In this respect, it is better to use devices whose accelerating electrode is covered with a thin dielectric layer, for example, is made in the form of a grid of wire with enamel insulation 3, where losses due to leakage of the ion current through the accelerated electrode are much less dry.

A disadvantage of the known electric aeroionizers, including the aforementioned analogues, is the presence in the ionized by these devices of triatomic oxygen - ozone, which is a toxic gas that is harmful to the respiratory system.

In prototype 3, as in the other analogues considered, the main source of ozone is the air gaps located in places with the smallest distance between the tips of the emitter and accelerate 2003113676

with a working electrode, where the electric field voltage has peak values.

The technical problem, which is aimed by the claimed utility model, is to reduce the ozone content by eliminating peak values of tension.

The indicated technical result is achieved by the fact that a resistor connected between the accelerating electrode and the ground, and dielectric electric field correctors placed on the accelerating electrode in places with the smallest distance from the emitter tips.

The functional diagram of the ionizer is shown in the figure, where it is indicated:

1- emitter;

2- high voltage source;

3- accelerating electrode;

4- resistor;

5- electric field correctors.

The principle of operation of the air ionizer is as follows: the air ions formed under the action of high voltage on the emitter tips move towards the accelerating electrode. Bypassing the latter, some of them go beyond the device to the consumer, for example, the patient.

The other part settles on top of the electrode insulation and on the surface of the dielectric correctors. Due to the finite insulation resistance of the wire, part of the ions in contact with the accelerating electrode lose their charges flowing down the resistor to the ground. The resulting voltage drop across the resistor is an integral part of the total voltage at the accelerating electrode, which allows, by manipulating the value of the resistor, to establish the optimal value of the accelerating voltage corresponding to the maximum emission. The electric potentials on the correctors are higher than in other parts of the accelerating electrode due to less leakage of electric charges. The local electric fields formed by them compensate for the peaks in the intensity of the main field, which eliminates the main cause of ozone formation.

An experimental sample of the proposed eroionizer was made and tested, in which dielectric beads strung on an accelerating electrode and located opposite the emitters were used as electric field correctors. Technical parameters of the sample are given below.

1. The area of the emitted surface (120x270) cm.

2. Number of needles (number of correctors) 24.

3. The voltage on the emitter is constant 7.2 kV.

4. Shaper resistance 150 mOhm.

6. Emission current and specific ozone content

without corrector 7 μA / 0.15 mg / m

7. Emission current and specific ozone content

5 μA / 0.06 mg / m

Note: measurements but n.a. 6 and 7 leveled at a distance of 10cm

from the surface of the radiation.

Thus, with the introduction of correctors, the ratio improved

emission current and specific ozone content 1.8 times. 4
