Abstract:

The analytical model of solution induced current and magnetic induction intensity which decides the scale inhibition efficiency has been established by analyzing the working principle of electromagnetic induction water treatment device and the key factors affecting water treatment effects. Based on the functional relationship between the average power of the induced current in the solution and the excitation signal,a kind of optimum method for locking the bipolar pulse feed LC circuit to produce resonance is brought forward. The automatic frequency tracking technology is used for real-time adjustment of pulse output frequency,so as to ensure the optimal frequency of the resonant circuit output excitation signal,and,as a result,to improve the treatment effect of electromagnetic induction water treatment device. Experiment results show that the water treatment device can more effectively improve the descaling efficiency and has higher adaptive capacity for the environment.

Key words: electromagnetic induction water treatment, LC circuit, analytical model, phase-locked loop
