Establishment and Simulation of the Mathematical Model of Particles Moving and Distributing in ESP

摘要

The purpose of the paper is to study on the laws of dust particles moving and distributing in ESP(Electrostatic Precipitator). By the means of mathematical theory and the finite difference method, a completed mathematical model of particle moving has been built up and solved under supposing a series of reasonable boundary condition. The complicated moving law of particles in ESP has been simulated by the numerical evaluation and Simulation Language MATLAB software. It indicates that concentration distribution of particles in cross section inside of ESP is in accordance with the rule of exponential function. The concentration near the collecting electrode is higher than the concentration near the corona electrode. The results show that numerical calculation of mathematical model in ESP is acceptable.
