ribs for different volumes of source water and low efficiency of monitoring the state of source water and electrodes.

The purpose of the proposed solution is to expand the ability to control the level of silver ion concentration in a wide range of preset volumes of treated water, providing increased efficiency of monitoring the state of the source water and electrodes.

This goal is achieved by the fact that the known prototype device, containing; its current source, electrodes, of which at least the anode is made of silver, a logic unit connected to a timer, an indication unit and the output of a control unit connected to the inputs to the electrodes, It is proposed to equip the concentration regulator, as well as a key element in which the inputs are connected to the outputs of the current source, the outputs are connected to the electrodes and control; the input is to the output of the logic unit connected by its inputs to the outputs of the concentration regulator.

The specified set of essential features is unknown from the prior art, which allows us to consider this utility model as appropriate; the eligibility criterion is “novelty,

In addition, the combination of these characteristics — the introduction of a concentration adjuster and a key element, as well as their connection with each other and with other blocks of the ionizer — makes it possible to obtain new results (achieve this goal), namely:

-to expand the ability to control the level of concentration of silver ions in a wide range of preset volumes of treated water by introducing a concentration adjuster, which allows you to set the volume (flow) of the treated water, silver separation and processing time,

source water and electrodes by maintaining a constant amplitude of the current through the water between the electrodes and eliminating the influence of current on the controlled amplitude of the voltage on the electrodes when controlling the flow of silver.

The essence of the proposed ionizer is illustrated by a drawing with a diagram where the following notation is adopted: 1 - current source, 2 - electrodes (either one anode or anode and cathode are made of silver), 3 - logic block, 4 - timer (time counter), 5 - display unit, b - control unit, 7 - concentration adjuster, 8 - key element, 9 - volume (flow) of water adjuster, 10 - silver flow adjuster, 11 - electrolyzer

The ionizer contains a current source 1, electrodes 2, of which at least the anode is made of silver, a logic unit 3 connected to a timer 4, an indication unit 5 and the output of a control unit b connected to the inputs to the electrodes 2, a concentration regulator 7, and also a key element 8, in which the inputs are connected to the outputs of the current source 1, the outputs are connected to the electrodes 2, and the control input is to the output of the logic unit 3 connected by its inputs to the outputs of the concentration adjuster 7, which includes a volume control unit for the treated water 9 and a silver flow rate setting unit 10, and electrodes 2 are placed in the electrolyzer 11. Timer 4, display unit 5, control unit b, concentration adjuster 7, key element 8 can be performed on a commercially available element base - semiconductor elements, and logic unit 3 is based on a microcircuit (single-chip microprocessor).

The operation of the ionizer is as follows. Water treated with silver ions (for disinfection) is in the electrolytic cell 11 or continuously passes through it. Under the influence of an electric current, silver ions enter the water from the anode and gradually dissolves. The degree of disinfection of Di water depends on

silver ion concentration (based on the mass of silver dissolved under the influence of current). The current strength is determined by the voltage at the electrodes 2 and the electrical resistance of the water between them. The concentration of silver in water in accordance with the Faraday law depends on the volume of treated water, current density and processing time. The required silver concentration is set by the concentration adjuster 7 (the volume of the treated water — the adjuster of the volume 9 and the amount of soluble silver — the adjuster of the consumption of silver 10) and is set by the processing time and the average current value. The processing time is determined by timer 4, and the maximum current strength (amplitude) is set by current source 1. The average current value is controlled by a key element 8, working with a constant switching frequency, by changing the time of its on state during the switching period, which implements logic block 3. Thus Thus, the average value of the current between the electrodes 2 is regulated pulse by means of the key element 8 from the maximum value to zero at a constant amplitude specified by the current source 1. For example, for radiation reduced concentration of silver silver flow setpoint 10 is set so that via a logic block 3 to provide the least time of the closed condition of the key member 8 during each commutation period and reduce the average value of current between electrodes 2 without diminishing its amplitude.

The control unit b monitors the voltage amplitude level at the electrodes 2, which is proportional to the current amplitude. If an unacceptable decrease in voltage (decrease in the resistance of the interelectrode space) at the electrodes 2 of the electrolyzer 11 is caused by either a short circuit of the electrodes 2 or an excessively high salinity of the source water, the control unit {1) will be activated, signaling through the logical unit 3 on the invasion unit 5 that emergency (water is not disinfected or is not suitable for consumption due to excessive salinity). Similarly, the indication unit 5 is triggered through the logic unit 3 from the control unit b, if the voltage at the electrodes 2 exceeds the upper permissible value, which happens either when cladding, contamination or unacceptable wear of the electrodes, or when the water resistance is excessively high (for example, distilled water, through which it is not possible to provide the required current). This situation is also an emergency, since the required efficiency of disinfecting water with silver ions in the electrolytic cell is not provided 11. During normal operation of the electrolytic cell 11, the display unit 5 signals the absence of an emergency situation, and the timer 4 and the logical unit 3 provide the required water treatment time. Therefore, the effectiveness of monitoring the state of the source water and the electrodes 2 depends on the accuracy of determining the upper and lower limits of the voltage values on the electrodes 2. Efficiency (accuracy of determining the limit values of voltage) increases if there is no dependence of these limits on the magnitude of the current between the electrodes, the average value of which changes when the regulation of the concentration of silver ions, and the amplitude is constant, which takes place in the proposed ionizer and is not in the prototype

Thus, in the proposed device, broader possibilities are obtained for controlling the level of silver ion concentration with an increase in the allowable range of preset volumes of treated water. This is achieved through the introduction of a concentration adjuster, which allows you to set the volume (flow) of the treated water, silver consumption and processing time (the number of controlled parameters has been increased), which is realized by pulse control of the average current

and a corresponding change in water treatment time.

The efficiency of monitoring the state of the electrodes and the source water is improved by maintaining a constant value of the amplitude of the current through the water between the electrodes when controlling the silver flow rate. In this case, the voltage amplitude at the electrodes, which is proportional to the current amplitude, depends only on the resistance (degree of salinity) of the source water and the state (degree of contamination, cladding, and deterioration) of the electrodes, which is determined by the control unit. Deviation of this voltage beyond the tolerance (above and below the maximum permissible limits) is considered emergency and does not correspond to the required quality of water treatment. In the prototype, the continuous mode of maintaining the current excludes its change, that is, the possibility of controlling the silver concentration decreases (it is possible only due to the processing time), since in the opposite case the quality of monitoring the state of the electrodes and water worsens (a change in the controlled current affects the voltage on the electrodes).

To check the quality of water treatment, an ionizer was created in accordance with the proposed solution. When testing the ionizer, in particular, it was found that the silver concentration achieved with an unchanged volume of treated water is from 0.5 to 25 mg / l and the error of its provision does not exceed 3%. The ionizer provides control over the state of the electrodes and the degree of salinity of the treated water in the entire range of the obtained concentration of silver ions with an error of no more than 2%.
