Patent ID: 11908619

Abstract:
An electromagnetic protection device is proposed to prevent adhesion of paraffin and other impurities dissolved in a hydrocarbon liquid to the inner surface of a metal pipeline. The device includes a power supply (battery or industrial electric grid), microprocessor unit, radiating antenna, antenna amplifier including solenoid, MOSFET transistor, capacitors, current and voltage sensors. A virtual capacitor, participating in generating electromagnetic waves preventing the adhesion, is formed between surfaces of the pipeline and a conductive part of the radiating antenna. The microprocessor allows setting an optimal operating mode of the device. The device is preferably furnished with two mount units including extendable rotatable spacers and flexible bands, adjustably fixing the device and radiating antenna to the pipeline. Each spacer includes a bushing including three connected hollow cylinders, two of which have threadings on inner surfaces, and two rods with mating threadings, enclosed in the cylinders, providing for moving the rods therein.
