SMALL INSTALLATION FOR OZONIZATION OF DRINKING WATER

HOME

The device relates to environmental protection and can be used for domestic cleaning of water contaminated with organic compounds (petroleum products, pesticides, etc.) and microorganisms, and can also be used in food, agricultural industries for storing perishable products, for medical purposes for treatment and disinfection.

Known devices for water ozonation / 1,2 / containing a compressor, a discharge device, a high voltage transformer, in the primary circuit of which there are a thyristor switch and a capacitance, forming an oscillating resonant circuit with a transformer dissipation inductance, to the terminals of the secondary winding of which a discharge device is connected.

Among the shortcomings of these devices, it should be noted the relative complexity of the thyristor switch control unit, the complicated design of the ozonizer, the operation of a high-voltage transformer at the frequency of the supply network, which limits the performance of the ozonation installation.

The technical task of this utility model is to achieve the minimum installation dimensions, simplify the design of the ozonizer, increase reliability, increase the productivity of the ozonation installation.

The essence of the proposed technical solution lies in the fact that the installation for the ozonation of drinking water contains a compressor, a discharge device, an ozonizer, a high voltage transformer, the primary winding of which is connected in series with the capacitance, and the secondary winding is connected with a discharge device, the thyristor, anode and cathode of which are connected to the positive and negative clamps of the bridge. The thyristor control circuit contains a resistor, one terminal of which is connected to the positive terminal of the rectifier bridge, and the second terminal is connected to the input of the control pulse generator and a capacitor, the second lining of which is connected to the negative terminal of the rectifier bridge. The discharge device (ozonizer) consists of an internal cylindrical electrode (stainless steel) and an external electrode (aluminum foil), between which there is a small-sized glass tube and an air gap.

The use of cylindrical electrodes made of stainless steel and aluminum foil, as well as the use of a small glass tube reduces the consumption of materials in the design of the ozonizer, which makes it compact and technologically advanced. Using the compressor winding as a circuit element in series with the power circuit lowers the input voltage of the network, and, therefore, increases the reliability of the elements of the electronic circuit and makes it possible to use them with low voltage (current) specifications. the principle of operation of a small-sized installation allows you to form a pair of pulses for the period of the input voltage of the network double the frequency of occurrence of the discharge, and, consequently, the efficiency of ozone generation

Ha figure 1 presents a diagram of a small installation for ozonation of drinking water.

Figure 2 - design of the ozonizer.

Figure 3 - diagram of the installation.

The installation comprises a compressor 1, a rectifier bridge 2, a resistor 3, a capacitor 4, a control pulse shaper 5 of a thyristor 6, an oscillating circuit from a storage capacitor 7 and a transformer 8, a discharge device from two electrodes 9.10 and a glass tube 11, an output device for ozonation, having a connecting ozone-resistant tube 12, an ozone atomizer 13 immersed in a glass vessel with water 14. The glass vessel 14 may be equipped with a filter 15 and a discharge of the ozone-air mixture 16. The pulse shaper 5 is made for Foot control thyristor 6 and consists of a transistor 17, resistors 18,19. The input of the shaper 5 is the collector of the transistor 17, and the output of the second output of the resistor 19. The ozonizer (Figure 2) contains an external cylindrical electrode 9 made of aluminum foil, a glass tube on which the external electrode 9 is located, and centered relative to the walls of the tube 11 by spacers 20 internal elektrode 10, made structurally cylindrical stainless steel. Gaskets 20 are made of an ozone-resistant dielectric.

The device operates as follows. The supply voltage (Uc) (Figure 3, a) through the compressor winding 1 is supplied to a half-wave rectifier 2. In the first half-cycle, a pair of rectifier diodes 2 are turned on. The voltage on the capacitor 4 (Uc4) (Figure 3.6) starts to increase, simultaneously the storage capacitor 7 is charged (Fig. C, c). When the voltage of the capacitor 4 reaches a threshold value at time tl, an avalanche-like process of opening the transistor 17 and the thyristor 6 occurs.

When opening the thyristor 6, the oscillatory recharge of the capacitor 7 occurs through the primary winding of the transformer 8 and thyristor 6. A short high-voltage pulse of 5-8 kV appears on the secondary side of the transformer (Figure 3, d).

In the second half-cycle of the input voltage, the process is repeated, and the discharge of the capacitor occurs similarly. During the period of the supply voltage, two high-voltage pulses are transformed into the secondary winding, i.e. discharge frequency on the discharge device - ozonator - 2f.

When air is supplied from the microcompressor 1 to the glass tube 11 of the ozonizer, air ionization occurs in the discharge gap. As a result, the resulting ozone-air mixture enters through the tube 12 and the atomizer 13 into the prepared vessel 14 with drinking water. the ozonized species can withstand a certain time and after the oxidation reaction it is ready for use. For better treatment of ozonated water, you can pass it through filter 15 (for example, activated carbon).

The described installation is registered by the State. standard of Russia, has the technical conditions TU-3488-001-22627682-93, the conclusions of the sanitary-hygienic laboratory of the Bashkir Center for Sanitary and Epidemiology 4QQKoro supervision, the Scientific and Technical Council of the Ministry of Health of the Republic of Bashkortostan, the Base Certified Laboratory Bashvodokanal and the Municipal Certified Ecological Laboratory of Ufa.
