Description

The invention relates to the treatment (activation) of water systems (liquids) in a magnetic field and can be used to prevent the formation of scale on the walls of heat power devices in the chemical, metallurgical, and energy industries.

A device for magnetic fluid processing is selected as a prototype. It comprises a removable magnetic core located outside the housing, which is made up of hollow sections and is equipped with volume gratings installed inside sections that are made of ferromagnetic material. permanent magnets located between sections. A disadvantage of the known activator is that in such a geometry of the arrangement of the magnetic elements it is not possible to obtain high values of the magnetic field gradient. In addition, magnets, hollow section housings and gratings occupy a significant proportion of the fluid flow cross section, thereby increasing the hydraulic resistance of the apparatus.

An object of the invention is to increase the efficiency of magnetic treatment of a liquid.

This goal is achieved in that the magnetic activator, comprising a steel casing of rectangular cross section, having two expanders with flanges and a hatch with a cover, assemblies of magnetic elements magnetized perpendicular to the largest cross section, mounted end-to-end in cassettes placed in the casing in parallel planes is equipped with ferromagnetic plates placed in parallel in the gaps between the assemblies, and magnetic elements are placed in assemblies with alternating polarities.

Placing ferromagnetic plates in the gaps between the assemblies leads to a saving of magnetic elements (up to 40%), while the magnitude of the magnetic induction vector in the gaps remains practically unchanged. The calculation of the average values of B and cU / dx was carried out using the method of photographing magnetic spectra for various cross sections, starting from a plane that coincides with the surface of the magnetic element, Measuring simultaneously the values of the vector

by induction (B) in the same sections by the ballistic method, B was calculated at other points in photographs of the magnetic spectrum. Above the junction of two washers in the assembly, having the opposite direction -

In areas located opposite the passive assembly, there are regions of maximum dB / dx values (parallel to the assembly plane). These areas play a major role in the process of water activation. Placing the magnetic elements in an alternating polarity assembly increases the magnetic field gradient at these locations.

All this together leads to the predominant formation of crystals of impurities (hardness salts) in the volume of the solution. At the same time, stiffness salts are deposited in smaller amounts on the walls, which means that scale will be deposited less.

Figure 1 presents a section of the apparatus in a vertical plane; figure 2 - section aa in fig. 1, FIG. 3 is a section bB in FIG. 1.

The magnetic activator consists of a steel housing 1 of square or rectangular cross section, with expanders 2. connecting the square housing 1 to the main pipe 3 by means of flanges 4. Through the hatch 5, cassettes 6 are installed in the housing, containing - - active assemblies

7 (figure 2) and

N -1

passive assemblies 8 (N is the number of assemblies in one cartridge; seven are shown in FIGS. 2 and 3).

Active and passive elements are either pressed between two sheets of aluminum or clamped between them by screws. The assemblies slide into the longitudinal grooves on the inner surface of the cartridge.

Thin steel partitions are welded inside the expanders 2 to distribute the flow of water through the cassettes.

The device operates as follows. The solution (water) flowing in the gaps between the assemblies, as well as in the gaps between the extreme active assemblies and the cassette body, is exposed to a magnetic field both in areas of a uniform field and in areas of its greatest gradients. As a result, water becomes active, which is used in technological processes (boilers, heat exchangers, concrete preparation, watering crops, etc.).

Installation and replacement of cassettes is done through the hatch. For cleaning, assemblies are removed from the cassettes. Assembly changes are easily carried out in cases where it is required to change the nature of the magnetic field.

The proposed device activator has the following advantages compared with similar devices:

the possibility of implementing settlement

values of the magnetic induction vector B in the regions of a uniform magnetic field and

the possibility of creating sections with alternating polarity of the magnetic field, up to the realization of crossed fields by installing additional cartridges rotated 90 °;

an increase in the residence time of the liquid in magnetic poly, which leads to an increase in dose, in T.

activator cost reduction as a result of saving of magnetic elements
