摘要：
In order to further explore the transporting principle of the charged particles inside the single-stage double-vortex collecting plate electrostatic precipitator(ESP), and to enrich the dust removal mechanism of this type of ESP, we established a mathematical model of its particles transporting under the force fields, the flow field, and the diffusion field as well as the corresponding boundary conditions on the basis of its structural characteristics; mathematical software MATLAB was used to solve the equation of the simulation transporting model; experiments on collection efficiency was performed to compare with the simulation results. The results show that the establishment of the internal charged particles transporting model can explain the transporting principle and the boundary conditions of the model were appropriate; mathematical simulation solved by the MATLAB software shows that, under certain operating conditions, within the 0~14 μm particle size range, dust removal efficiency gradually increases with increasing particle size. When the size of particles increases from 2 μm to 14 μm, the dust collection efficiency will increase from 85.2% to 94.8%. The experimental results are consistent with the trend of MATLAB simulation results, proving that the simulation is reliable. The results indicate that single-stage double-vortex collecting plate ESP has a super function on fine particles and thus has a profound application prospect. © 2017, High Voltage Engineering Editorial Department of CEPRI.
