METHOD OF REMOVING MINERAL, BIOLOGICAL AND ORGANIC DEPOSITS AND SYSTEM FOR REALISING SAID METHOD Russian patent published in 2013 - IPC F28G9/00 C02F1/48 

FIELD: chemistry.

SUBSTANCE: cleaning method is realised using electric and structured magnetic fields, including: opposing magnetic modulated or non-modulated fields and radial electric modulated or non-modulated fields; closed magnetic fields with a periodic structure along a stream of aqueous medium; magnetic fields which cross at certain angles in the volume of an aqueous medium which is in both stationary and dynamic state, as well as formation of local zones with high concentration of impurities and colloids. This enables to measure physical and chemical properties of the aqueous medium by conducting chemical reactions therein, primarily in dissolved impurities and colloids through resonance electromagnetic-acoustic action aimed at modification of physical and chemical properties thereof, intended to stimulate self-cleaning processes of the aqueous medium. The method is realised using a medium modification system comprising: devices which generate opposing electromagnetic modulated or non-modulated fields along and opposite the flow of the medium and by electrodes lying on the axis of the tube, which generate radial electric modulated or non-modulated fields, a device which generates a closed magnetic field with a periodic structure along the stream of the medium.

EFFECT: invention enables to efficiently clean a heat-exchange surface and significantly cut expenses on use and repair of equipment in which heat exchange takes place.
