Description

The invention relates to the field of liquid media, and in particular to a method of physicochemical processing of liquid media and a device for its implementation, and can be used in chemical, petroleum, petrochemical and other industries to intensify various physico-chemical processes: homogenization, emulsification, dissolution etc.

The method of physicochemical treatment of liquid media and a device for its implementation are widely known. (Ultrasonic cavitation processing of fuels on ships. SP Zubrilov et al. Shipbuilding, 1988, 80 pp.).

A known method of processing liquid media, in which cavitation is excited by a rotary apparatus and the processed fluid is forced through its zone.

A known device containing a rotating rotor and a fixed stator, containing holes on the mating surfaces between the cylindrical part of the rotor and the inner surface of the housing has a removable sleeve forming a sliding bearing, the end part in contact with the stator, the clamped cover, while the rotor is endowed with additional holes connecting the rotor cavity and the stator.

The disadvantage of this method and device is that they do not allow you to influence intramolecular bonds and, therefore, the number of active molecules, which does not allow to intensify technological processes in liquid media containing molecules with a higher activation energy.

The present invention solves the technical problem of the intensification of technological processes in liquid media, by increasing the number of molecules with a higher activation energy.

This problem is solved by the fact that in the method of physico-chemical treatment of liquid media, including cavitation effects on the processing medium, according to the invention, the processing medium is additionally exposed to a magnetic field created in the cavitation zone.

This problem is also solved by the fact that in the device for physicochemical processing of liquid media containing a rotating rotor and a fixed stator, provided with holes on the mating surfaces, and a working chamber, and according to the invention, magnets are arranged in pairs on a working chamber housing, arranged around a circle on one straight with the holes of the rotor and stator so that the diametrically opposite magnets have opposite poles.

In this case, the device contains natural or electric magnets. Moreover, electric magnets create a rotating magnetic field in the working chamber.

The drawing shows a device for implementing the method of physico-chemical treatment of liquid media.

The device includes a housing 1 of the working chamber, a shaft 2, on which the rotor 3 is fixed. A stator 4 is attached to the rotor 3, pressed by a cover 5, a sealing ring 6. The rotor 3 is provided with holes 7 located uniformly around the circumference at the level of the holes 8 of the stator 4.

Magnets 9 are mounted on the housing 1 of the working chamber so that the diametrically opposite magnets have different poles and are located on the same straight line with the holes 7, 8 of the rotor 3 and the stator 4. The device is equipped with a pipe 10 for introducing the processed liquid medium, and an outlet pipe 11. Shaft 1 is sealed with stuffing box packing 12.

The method is implemented in the device as follows.

Processed liquid medium is supplied into the pipe 10 under pressure. The shaft 2 is driven into rotation. The liquid medium is forced through the hole 7 of the rotating rotor 3 and the hole 8 of the fixed stator 4. In this case, there are conditions for the excitation of cavitation in a liquid medium, the zone of which is determined by the cavities of the holes 7, 8 in the immediate vicinity of them. In this case, the magnetic field lines penetrate the cavitation zone. In cavitation bubbles ionized molecules arise. It is known that an infected particle crossing a magnetic field experiences the action of a force called the Lorentz force, which is directly proportional to the speed of this particle and the magnetic field strength. It is also known that the velocities acquired by particles during the “collapse” of cavitation bubbles reach significant values. Therefore, ionized molecules experience significant efforts that can break or weaken bonds. This leads to the emergence of active molecules, which, due to the interaction, create new compounds, which is what the goal is achieved: the intensification of technological processes.
