Based on the online electromagnetic scale suppression dynamic simulation table designed by our team, the magnetic induction intensity in the cavity of single-and multi-layer winding electromagnetic water processor is simulated and analyzed by using numerical simulation. The relationship between the magnetic induction intensity of the inner cavity and the number of turns of the coil, wire diameter, and inner diameter and the effect of the segment on the intensity of the magnetic induction in the inner cavity are analyzed. According to the Bio-Savarts law, the formula for calculating the magnetic induction intensity in the cavity of multi-layer winding electromagnetic water processor is derived. Moreover, the structural parameters of the processor are determined based on the simulation results of the Maxwell equations. According to the simulation results, we make a new multi-layer winding electromagnetic water processor, which will be used on the online electromagnetic scale suppression dynamic simulation table in the future.INDEX TERMS Magnetic induction intensity, numerical simulation, winding electromagnetic water processor, electromagnetic anti-fouling treatment.
The absorbance values of specific configuration solutions under different magnetic treatment conditions are studied using the UV method based on the circulating dynamic simulation experiment platform for the anti‐scaling of electromagnetics. Additionally, the relationship between the absorbance value and solution concentration is determined. Moreover, the nucleation rate of CaCO3 is calculated using the absorbance value. The influence of the specific magnetic field on nucleating rate is analyzed. Subsequently, the magnetic memory effect and time of CO3−2 and water are studied. Results show that the magnetic treatment changes the nucleation rate of CaCO3 and the critical oversaturation of the solution by acting on CO3−2. This treatment also can promote the dissolution of CaCO3 in water by changing the properties of water. These two aspects all exert memory effects; however, their respective memory times are different. Moreover, the results show that the magnetic treatment can reduce the critical oversaturation of the CaCO3 solution and accelerate the nucleation rate. Furthermore, the memory time of the magnetic field acting on CO3−2 and the properties of water are 45 min and 78 h, respectively.
