FIELD: piping maintenance.
SUBSTANCE: device for cleaning the inner surface of pipes and heat exchange equipment with an alternating magnetic field. The proposed device includes an elementary frequency generator operating in the frequency range of 30-1000 kHz, the output of which is connected to an amplifier, the amplifier output, in turn, is connected to an inductor generating an alternating magnetic field, an amplitude modulation generator operating in the frequency range 1-500 Hz and connected via a modulator to an amplifier. The amplitude modulator of the elementary frequency, the output of which is also connected to the amplifier. A magnetic circuit that surrounds a pipeline with liquid along the perimeter and at the same time is the magnetic core of an inductor. The device is additionally provided with an elementary frequency amplitude frequency modulation generator and/or an elementary frequency modulation generator. Moreover, the elementary frequency amplitude modulation frequency modulation generator is connected to the input of the elementary frequency amplitude modulation generator and operates in the entire frequency range or its part within the range of 1-500 Hz. In this case, the frequency of modulation of the frequency of modulation of the amplitude of the elementary frequency must be at least 10 times lower than the lower value of the range of modulated frequencies. The elementary frequency modulation generator is connected to the input of the elementary frequency generator operating in the entire frequency range or its part within the range of 30-1000 kHz. In this case, the modulation frequency of the elementary frequency must be at least 10 times lower than the lower value of the range of modulated frequencies.
EFFECT: increasing the efficiency of cleaning the inner surface of pipes and heat exchange equipment, as well as the prevention of biofouling.
