| An experimental model was established to research the effect of working voltage, entrance velocity, porosity, corona wire number on the dust removal efficiency of embedded electrostatic fabric integrated precipitator. The optimal structure parameters of the integrated precipitator were obtained, and the working voltage and entrance velocity were optimized as well. The classification efficiency of the optimized integrated precipitator was tested. The experimental results showed that with the increase of the aperture ratio, the dust removal efficiency increased first and decreased later. When the opening porosity was 0.356, the combined dust removal efficiency reached to maximum. Within a certain range, the dust collection efficiency increased with the working voltage rising. When the voltage was 40 kV, the dust removal efficiency was 97.1%. The corona line had great influence on dust removal. When the corona line number was 7, the combined dust removal efficiency reached to maximum. Under the optimal structure parameters and the optimal operating conditions, the removal efficiency of PM2.5 was 92.4%. In the same experimental conditions, the removal efficiency increased by 11% compared to the electrical precipitator. |
