A brief description of the drawings.

As an example implementation in FIG. 1 shows a section of the proposed "Device for mineralization of water. In FIG. Figure 2 shows the dependence of the rate constant of NaCl dissolution on water temperature. In FIG. Figure 3 shows an example of the dependence of the rate of passage of water through the mineralizer on the rate constant of dissolution of NaCl.

A device for mineralizing water contains:

the suction port of the pump (1) connected in series with the water temperature sensor (2) installed on the suction port of the pump (1), the pump (3), the discharge port of the pump (4), and the flowmeter (5) installed on the discharge port of the pump (4) , water inlet unit (6), mineralization unit (7), water outlet unit (8). In FIG. 1, an embodiment is shown as an example when the mineralization unit (7) is made in the form of a hollow cylinder (9), on the bases of which water-permeable porous partitions (10), (11) are installed, and containing 3 steps between the water-permeable porous partitions mineralization separated by water-permeable porous partitions (12), (13) containing various loads (14), (15), (16);

programmable controller (17) connected to the water temperature sensor (2), pump (3), flowmeter (5) via communication channels (18), (19), (20).

Wherein:

the pump is configured to control the actual flow rate of water Q _f sucked by him.

The device operates as follows.

When the pump (3) is running, unsaturated water is sucked into the pump suction pipe (1), where the water temperature sensor (2) measures its temperature in real time and transmits the readings to the programmable controller (17) via the communication channel (18).

In the process of working in real time mode:

- determination of the temperature t of the incoming water by reading the readings of the water temperature sensor (2) by the programmable controller (17) through the communication channel (18);

- determination by the programmable controller (17) of the rate constant for the dissolution of salt in water K, depending on the measured temperature t. The present utility model allows various options for its determination, for example, according to a graph of the dependence of the rate constant of dissolution of salt in water K on water temperature t, (an example of the dependence of the rate constant of dissolution of NaCl in water on water temperature is shown in Fig. 2);

- determination by the programmable controller (17) of the required water flow rate Q _t , at which the saturation of water with minerals will be optimal, depending on a certain constant of the rate of dissolution of salt in water K. This utility model allows various options for its determination, for example, according to a graph of the dependence of the required water flow Q _t on the rate constant of dissolution of salt in water K (an example of the dependence of the required water flow rate Q _t passing through the mineralization unit (7) on the rate constant of dissolution of NaCl is shown in Fig. 3).

- determination by the programmable controller (17) of the actual water flow Q _f in real time by reading the readings of the flow meter (5) through the communication channel (19);

- comparison by a programmable controller (17) of the actual water flow rate Q _f with the required water flow rate Q _t in real time;

- adjustment by the programmable controller (17) of the actual water flow Q _f in the case where the difference between the actual water flow Q _t and the required water flow Q _{t is} greater than the permissible value ΔX. For example, in the case where Q _f <Q _{t, the} programmable controller (17) sends a command to the pump (3) through the communication channel (20) to increase the actual water flow Q _f , thereby Q _f , increases and approaches Q _t as much as possible. In the case where Q _f > Q _{t, the} programmable controller (17) sends a command to the pump (3) through the communication channel (20) to reduce the actual water flow Q _f , thereby Q _f decreases and approaches as much as possible to Q _t . In the case where Q _f = Q _t programmable controller (17) does not give any commands. Adjustment is carried out in feedback with a flow meter (5). In this case, the speed of movement of unsaturated water in the mineralization unit (7) becomes optimal for its saturation with mineral substances in the required amount;

- the conclusion of mineralized water from the device through the node output water (8).

The advantages of the proposed device are as follows:

- there is the possibility of water passing through 3 stages of mineralization, depending on the needs of the source water in various minerals;

- eliminates the possibility of undersaturation of the source water with minerals, since the rate of flow of water in the mineralizer, and, therefore, the saturation of water with minerals, will be regulated depending on the temperature of the source water.
