Description

1212969

The invention relates to the chemical structure of Art.

microbiological, oil refining, food and other industries, namely, devices for preventing Haratne formation on the walls of heat exchangers and elements.

The purpose of the invention is to reduce scale formation on the walls of heat exchangers and elements.

The drawing shows the proposed anti-scale magnetic device.

The device consists of a housing 1 with several pairs of permanent magnets 2 installed outside, which are spaced one from another, the values of which form a geometric progression. The inlet and outlet of the fluid is carried out using the inlet 3 and outlet 4 nozzles.

The anti-scale magnetic device works as follows.

Liquid or saline solution flows through the inlet 3 into the housing 1, where it is exposed to a magnetic field created by several pairs (typically 2-7 pairs) of permanent magnets 2 (or electromagnet coils) with alternating polarity. The liquid is discharged through the pipe 4. To achieve a high level of scale reduction, a pair of magnets 2 are set at distances whose magnitudes form a geometric progression, and the magnitudes of the magnetic field strength created by the sequence

a number of pairs of magnets constitute an arithmetic progression and increase in the direction determined by the movement of the fluid in the device. Based on the conducted experiments with waters containing calcium, sodium, potassium, iron, ikel and other salts, it was found that the average average magnetic field strength in the device should be 450-2800 Oe and depends mainly on concentrations of iron and calcium salts in water.

The data on the effect of the distance between the pairs of magnets and the magnitude of the magnetic field intensity on the effect of reducing the deposition of scale on the walls of the heat exchanging equipment are given in the table.

From the data of the table it is seen that the effect of ci-shzheni scale significantly depends on the values of the distances between the parades of the magnets and the values of the field strength in the gaps between the magnets, and the greatest effect is achieved with the values of the distances between the pairs of magnets subject to geometric progression, and at magnetic field strengths, subject to the law of arithmetic progression.

Installing the proposed counter-magical device in water treatment in front of the boilers reduces scale deposition on the walls of heat exchangers and components i, 2–2.8 times as compared with the use of known

devices.
