Hysteresis comparison method based electromagnetic scale removing and preventing method and scale removing and preventing device

Abstract

The invention discloses a hysteresis comparison method based electromagnetic scale removing and preventing method and a hysteresis comparison method based electromagnetic scale removing and preventing device. The method comprises the following steps: measuring a conductivity value and a temperature value of a water body to be treated through a data acquisition device; searching global optimum resonant frequency by an upper computer by utilizing a hysteresis comparison method according to the required data, and transmitting a control signal to a single chip microcomputer to control a high-frequency signal generator to generate an electromagnetic pulse with corresponding frequency; generating the electromagnetic pulse by the high-frequency signal generator at the global optimum resonant frequency to remove scale from the water body. According to the method and the device, a scale removing and preventing effect is obvious, and the frequency is automatically regulated to match the resonant frequency of the water body to achieve the best scale removing effect; the adaptability is high, the scale removing range is wider, the method and the device are limited to the water body of a single environment, and the application range is wider; by adopting the hysteresis comparison method, the problem that local optimum frequency is taken as the global optimum frequency by mistake because the curve of the conductivity value of the water body to be treated and the frequency of the electromagnetic pulse is not ideal enough is avoided.
