The invention relates to the field of magnetic bleaching and can be used in ore dressing, metallurgical, chemical industry, Taylor and nuclear power engineering, as well as in water supply for the purification of liquid media from magnetic impurities,

A electromagnetic filter known to clean process fluids Cll is known.

The disadvantages of this device are low efficiency due to inefficient design, significant loss of magnetic flux and as a result, the low efficiency of the magnetic deposition process.

The closest to the invention is an electromagnetic filter element containing cylindrical channels with a ferromagnetic porous nozzle, electromagnets, surrounding a closed magnetic circuit with a nozzle, cores fitted with ferromagnetic plates.

The disadvantage of the trials is low economical; because of the fact that the magnetic circuit contains double joints - Zor; the first is between the core and the plate, the second is between the plate and the body, which leads to an increase in the resistance of the magnetic circuit. The magnetic resistance also increases due to the presence of metallic ferromagnetic plates. This leads to additional magnetic flux losses and ultimately to a decrease in the efficiency of the cleaning process.

The aim of the invention is to increase the efficiency of the filter precipitator and the efficiency of the magnetic deposition process.

The goal is achieved by the fact that the intercardiac paccToia and the diameter of each channel are in a ratio of 3: 2.

Fig, 1 shows the proposed filter section of one of its enclosures; 2 is the same / top view; FIG. 3 shows the measurement results of the magnetic field induction.

In the proposed device cores-magnetic cores without ferromagnetic plates. The absence of ferromagnetic plates is compensated for by the optimal choice of the inter-core distance t depending on the diameter I of the filter filter case. „Material nozzles. Increasing C (Fig 1) can only create separate filtering zones localized in the vicinity of opposing magnetic poles.

5 To determine the optimal ratios of P and D, measurements were made of a magnetic field in a spherical filter nozzle located in a cylindrical body with a diameter of 0 g (120, -1bO and 240 mm) placed between one pair of magnetic poles (figGo). The intensity of the external magnetic field H varied from 40 to 240 kA / m. The cores from steel 5 with carbon content up to 0.3% with the subsequent annealing are assembled according to the scheme of a closed magnetic value, Their ± orts tightly cover the hull. The total number of turns of magnetizing Q coils 4400. The induction of the floor in the gap gaps of the nozzle was measured using miniature Hall sensors.

As shown by the measurement results (FIG. 3), the induction of the magnetic field 5 in the magnetized nozzle in the axial direction is reduced due to the Spread of the magnetic flux over a large volume of the nozzle. Using the principle of superposition, it is easy to determine at what distance it is necessary to install the next pair of magnetic poles, with which the induction field will be almost the same throughout the entire height of the nozzle. 5 Regardless of the case diameter, this ratio tvD 3: (FIG. 2), depending on the required depth of cleaning along the height of the filter housing, can be installed several electro-magnets,. . .
