The invention relates to methods for the ionization of air and can be used, for example, in textile production in the processing of natural artificial fibers to neutralize static electricity.

The aim of the invention is to improve the efficiency of the device due to an increase in the concentration of ions in water.

When processing by direct current in the cathode zone of the flow-through electrochemical activator, in the near-electrode zone an activated liquid layer is formed containing an excess of negative ions, while the water has an alkaline reaction and is a solution of aqua ions: 01 OHjO); HE-.(); Of - (HjO); .) etc. After the electroactivation ceases for some time, the water remains in a metastable state characterized by abnormal values of physicochemical parameters — a sharp change in pH and redox potential (ORP), and the metastable state of water can be maintained at a low intensity of energy exchange with the environment for a long time. a time not commensurate with the lifetime of the known charged particles of hydrated and free electrons, free radicals, etc. The energy that water molecules acquire as a result of the process is stored in it in a form that causes a deviation of the molar volume (density) from the equilibrium state at constant pressure and temperature. These features significantly affect the preservation of the charge of aeroion; moreover, ozone promotes additional ionization of the working area air and improvement of its sanitary and hygienic parameters, air enriched with ozone in concentrations characteristic for. 20-40 µg / m of atmospheric air, helps to preserve light negative aero ions, compensates for the loss of atmospheric ozone, neutralizes harmful impurities in the air and deodorizes it. The intensity of ion formation is not significantly affected by the alkalinity of the activated water, but by its redox potential, which determines the ratio of negative to positive ions in water. The use of electroactivated water with a negative pH value of 8–9 is mainly due to the minimal enrichment of the air environment with aerosol, since there is a slight irritation of the tissue of living organisms. The redox potential (1000-1200) mV is due to the optimal level of aeroionization in the human respiration zone, capable of producing about 10,000 ions / cm of light ions.

Example. The humidified air was ionized, in which water was subjected to direct current treatment in an electrochemical activator, in which the flow chamber is a cathode chamber. The flow-free anode chamber was filled, for example, with a 0.5-1% sodium bicarbonate solution (baking soda) and separated from the flow-chamber by a cation-exchange membrane. As the anode and cathode, plate electrodes made of titanium coated with platinum were used, 015 mm. A constant current was passed through the electrodes, the value of which depends on the flow rate of the liquid for dehumidification and provision of the required ORP, and when the water was passing through the near-electrode zone of the water during the electroactivation process, an increase in the ORP occurred with a slight change in pH. The circulation of water in the electrode zone was carried out by a forced-flow pump, the speed of which was regulated. Activated water with a pH of 8-9 and ORP - (1000-1200) mV was fed through a pipe. to the wires of the humidification system to the pneumatic nozzles, where it was dissipated by compressed air enriched with ozone in a concentration of 50-100 µg / m. When sprayed in the torch of the nozzle, there was a fine splashing of water, contributing to its complete evaporation, and a-concentration of ozone in the working area of 20-40 µg / m

P corresponded to the natural concentration of ozone in the atmosphere, and the amount of light negative ions in the working zone did not exceed the sanitary standard of 10,000 ions / cm.

working area as a function of time; in fig. 3 — changes in the concentration of light aeroions as a function of pH and redox potential (all measurements were made with an ASI-1 instrument at a distance of 1.5 m from the nozzle) ..

The installation contains a pneumatic spray with pneumatic nozzles 1 water flow located on the water and air supply system in the form of water supply lines 2 and air 3. The flow-through electrochemical activator 4 is equipped with electrodes - anode 5 and cathode 6, which are located in the same plane, and . Separated by diaphragm 7, and in the near-electrode area of the cathode chamber, water is pumped by pump 8. A constant electric current from rectifier 9 is applied to electrodes 5 and 6. Pneumatic line is equipped with an ozonizer 10, which is supplied with voltage from a high-voltage transformer 11. The plant is equipped with water sources (water supply network) 12 and compressed air 13, control valves: float level control of water level 14, air flow controllers 15 - 17.

The installation works as follows.

in a way.

Water from the water supply network 12 through the float level regulator of water 14 enters the flow-through electrochemical activator 4. Electrodes 5 and 6 are fixed in the bottom or in the wall of the electroactivator 4, located in the same plane and separated by the diaphragm 7 in the form of an ion-exchange membrane, which separates non-flowing an anode chamber filled with electro (cast). A constant electric current is supplied to the electrodes from the rectifier 9, and the current density can be adjusted manually or automatically. The circulation of water in the near-electrode zone The pump is driven by a pneumatic drive, its capacity is regulated by the air flow regulator valve 17, the supply of activated water through the water supply line 2 to the nozzles 1 is carried out by the overpressure created inside the electroactivator 4, which is filled in the form of a sealed container. valves (regulators) of air flow 15 and 16. Compressed air from the air pipeline 3 enters the ozonizer 10, where under the action of a high-voltage glow discharge it enriches Sohn. Then it goes to the nozzles 1, providing artificial ionization and ozonation of the working area air. From the graph of changes in the concentration of light aeroions in the air of the working area over time (Fig. 2), it can be seen that, compared with a limestone device, the preservation of charge of negative bulk density increased 23 times. From the graph of the change in the concentration of light aeroions as a function of pH and ORP (Fig. 3), it is clear that in the range of change in pH 8-9, the most preferable range is (1000–1200) mV, which gives the required concentration of light aeroions.
