(54) FOAM DAMAGE

(57) The invention relates to foam-quenching devices, for example, during reagent treatments of water wells or foaming. The goal is to increase the efficiency of defoaming by utilizing the effect of bulk compression. As a result of the passage of current between the lengths of the tubes 3 and 9 (cathodes) and the body 1 (anode), the foam is heated and destroyed. At the same time, the current flowing in the foam is under the influence of the magnetic field of the magnets 5. According to the left-hand rule, the force resulting from the interaction of el. current with a magnetic field, is directed in the direction opposite to the direction of the spiral channels 7 in non-magnetic annular spacers 6, and creates resistance to the movement of foam from a pipe section 9 in these channels above the partition 8 and below the partition 8 contributes to the movement of foam into the pipe section 3. 2 .

WITH

The invention relates to devices intended for foam quenching, for example, during reagent treatments of water wells or foaming. i The aim of the invention is to increase the efficiency of defensive action due to the use of the effect of volumetric compression. FIG. 1 shows an electromagnetic foam breaker, a longitudinal section; FIG. 2 is a section A-A in FIG. one.

Electromagnetic Foam Destroyer soi: holds a conical case 1 made of electrically conductive material (steel, bronze, etc.) with a bottom 2 of a nonmagnetic current-conductor of its material (for example, fluoroplastic). On the bottom, e 2, a section of pipe 3 with half-ring openings 4 is screwed on the thread. The section of pipe 3 is made of conductive material (steel, bronze, etc.). On the bottom 2 there are magnetic rings 5, the surface of which is coated with a non-conductive material (varnish), alternating, with non-magnetic annular spacers 6, in which through spiral channels 7 are made, connecting the internal and external cavities of the device. A length of pipe 3 is plugged with a partition 8 into which a similar section of pipe 9 is screwed on the opposite side with non-magnetic spacers b and magnetic rings 5 mounted on it. For connection to the pipelines, an inlet 10 and outlet 11 of the coupling are used . The sections of pipes 3 and 9 are electrically interconnected through the partition 8. The negative terminals of the current source are connected to the sections of pipes 3 and 9, and positive to the conical body 1.

Electromagnetic foam destroyer works as follows.

After the couplings 10 and 11 are connected to the inlet and outlet pipes and the housing is filled with foam, a current is switched on in the circuit. At the same time, as a result of the passage of current between the lengths of pipes 3 and 9 (cathodes) and case 1 (anode), the foam is heated and destroyed, while the current flowing in the foam is influenced by the magnetic field of the magnets 5, which are positioned so that the direction from the north pole to the south between adjacent magnets corresponds to the upward direction. Then according to rule

In the left hand, a conductor with a current (in this case foam) in a magnetic field is acted upon by a force, which tends to move this conductor. This force is directed in the direction opposite to the direction of the spiral channels 7 (Fig. 2) in non-magnetic annular spacers 6, and creates resistance to the movement of foam from the pipe section 9 in these channels above the partition 8, and below the partition 8 contributes to the movement of the foam into the pipe segment 3. Thus, in channels 7 and pipe sections 3 and 9, the effect of volumetric compression of the foam is created, which contributes to its destruction.

The implementation of the magnetic system in the form of successively installed magnetic rings alternating with non-magnetic annular spacers allows the device to create a magnetic field concentrated in the places where non-magnetic spacers are installed, i.e., in the spiral channels that are made in them. The connection of the internal and external cavities of the device using spiral channels allows, using the interaction of electric current with a magnetic field and the shape of the channels, to create volumetric compression of the foam, leading to its destruction. At the same time, the device uses to destroy the foam the heat that is generated in the foam when an electric current is passed through it. The combined effect of volumetric squeezing of foam and its heating makes it possible to increase the efficiency of defoaming.

The proposed foam destroyer has an increased efficiency and productivity of defoaming agent, does not require highly qualified personnel service, which is especially important when it is used in field conditions.
