Simulation and design of the processing chamber of high-frequency electromagnetic processor

Processing chamber is an important part of high-frequency electromagnetic water processor. To determine what kind of processing chamber has better effect of antiscaling, the software, Ansoft Maxwell, which is based on the finite element method, is applied to simulate electromagnetic energy distribution in two common processing chambers. One processing chamber is set with coaxial electrodes and the other one is wrapped by spirals. The electromagnetic energy released to water and the distribution of instantaneous energy density of each chamber are compared. According to the simulation analysis, when the same electrical excitation is imposed on the same volume of water, electromagnetic energy of processing chamber with coaxial electrodes is far more than that of processing chamber wrapped by spirals. However, the electromagnetic energy of processing chamber with coaxial electrode decreases from the anode to the cathode, while the electromagnetic energy of processing chamber wrapped by spirals is distributed evenly. These analysis results can be definitely instructive to design the chamber of high-frequency electromagnetic processor.
