Numerical simulation for high gas velocity electrostatic precipitator with transverse collecting plates

The high gas velocity electrostatic precipitator (HGVESP) with transverse collecting plates was simulated by computational fluid dynamics (CFD) technology. The SIMPLE algorithm was used to calculate and the geometry model was divided by ICEM which is one kind of pre-processing software. The relationship of gas velocity, dust particle size and voltage was examined by FLUENT software. The results suggested that with the improvement of applied voltage and dust particle size, collection efficiency was increased and gas velocity became a favorable factor to improve collection efficiency in a certain range. The results shown that HGVESP with transverse collecting plates can not only has a high efficiency, but also increase treatment capacity, achieve miniaturization, and reduce disposable investment. Therefore, these can contribute to its wider application.
