Description

technical field [0001] The invention relates to a descaling and antiscaling device, in particular to a power circuit of an electromagnetic descaling device. Background technique [0002] During the long-term use of the boiler and the pipeline for conveying hot water, a layer of scale is easily attached to the furnace wall of the boiler and the inner wall of the pipeline. These scales affect the heating efficiency of the boiler or block the pipes, resulting in increased production costs or even shutdown. [0003] Among the current descaling technologies, the electromagnetic descaling technology is widely used because of its easy installation and low cost of use. The principle is to apply an electromagnetic pulse with the same natural frequency as the water molecular cluster to the water, causing the resonance of the water molecular cluster, thereby breaking its hydrogen bond, making the water molecular cluster smaller or becoming a single water molecule, increasing the activ...
