WITH

The invention relates to magnetic treatment of water and can be used to indicate the degree of magnetization of water and to determine the optimal magnitude of the magnetic field strength in order to intensify various technological processes.

A known method for indicating the degree of magnetic treatment is based on comparing magnetized and non-magnetized solutions by the frequency-dependent component of the polarization voltage generated by the low-frequency current (S.P. Rampel. Electronic device for tuning magnetic water treatment apparatuses. TsBTI, Sverdlovsky SNX, 1962).

However, this method is not applicable to all solutions and concentrations.

The closest in technical essence to the proposed one is a method for monitoring the magnetic susceptibility of aqueous solutions, based on measuring the value of the redox potential of the treated solution and the maximum value, and the time it reaches it, are judged on the magnetic susceptibility of the solution (USSR Author's Certificate No. 899491, cl. C 02 1/48, 1982).

The disadvantage of this method is the need for frequent replacement and calibration of electrode systems, the use of thermal compensation.

The aim of the invention is to increase the efficiency of control and the ability to control various wastewater.

This goal is achieved by the fact that, according to the method, the water flow is sequentially passed through the measuring capacitive cells before and after its magnetic treatment, and the degree of magnetization of the water is measured by simultaneously supplying rectangular pulses to both measuring cells, measuring the pulse delay time of each from measuring cells, determining the difference between the delay times, the magnitude of which determines the degree of magnetization.

Thus, it has been found that the claimed invention is novel and provides the ability to control the degree of magnetization of the magnetic field-treated water.

In order to prove that the features of the method match the criterion, significant differences were searched for similar features in other technical solutions known in science and technology in the main and related sections of MKI C 02 V, C 02 F, G-5 D, No known solutions were found.

Figure 1 shows a flow chart of the implementation of the proposed method; figure 2 is a functional diagram of a device for delaying pulses; Fig. 3 is a design of a measuring cell.

The pulse delay device contains two single-vibrators on microcircuits D1 and D2 (K155AP), an RS-trigger on microcircuit 03 (K155LAZ), a circuit R1C1 that provides the necessary initial state of the device, integrating circuits C3R3 and C4R4, coaxial electrodes that are part of the measuring cell , dual adjustable resistor R2 and resistor R5.

The single-shot on chip D1 is triggered by the leading edge of the input pulse, and the single-shot by D2 is triggered by the falling edge of the input pulse.

The durations of the pulses generated by the single vibrators are equal and can be controlled by the dual resistor R2. These pulses, after differentiation by the C3R3 and C4R4 circuits, are fed to the inputs of the RS flip-flop. When a signal arrives at input R, the trigger is set to O, if the signal is fed to input S, the trigger is set to G. Thus, a pulse of the same polarity as the input is generated at the output of the trigger, but delayed relative to it for a time equal to the duration of the pulse generated by the single-shot D1,

Depending on the capacitance C2 and C5 (C2 C5), the delay time varies. Thus, the delay time of the input signals by the pulse delay device depends on the capacity of the measuring cell, which is proportional to the dielectric constant of the treated solution:

After turning on the generator 7, the time delays (output 1, output 2) are simultaneously measured for the untreated and treated fluids, and their difference, which is used to judge the degree of magnetization of the solution.

When determining the optimal value of the intensity, a graph of the dependence of the difference in time delays Dgot of the magnitude of the magnetic field N. Using the maximum value of the function A f (H), the optimal value of the intensity of the magnetic field of apparatus 3 is set.
