Title:
SCALE REMOVAL/ADHESION PREVENTION DEVICE
Document Type and Number:
Japanese Patent JP2014131786
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a scale removal/adhesion prevention device capable of obtaining high effects at a low cost while conserving electric power consumption without entailing an undue structural convolution and of securing safety at the time of the use thereof.SOLUTION: The provided device comprises: a single DC power supply; a coil; a coil magnetic excitation circuit for magnetically exciting the coil; a controller for controlling currents permeated through the coil magnetic excitation circuit; and a current stabilizer for controlling current leaks and regurgitations, whereas the coil magnetic excitation circuit is constituted as a H-bridge circuit, whereas the controller is furnished with an electric signal generation means, whereas the controller induces magnetic excitation by permeating, through the coil, an AC current obtained by converting a DC current into a rectangular wave having an arbitrary frequency.
