| description | Flow distribution in electrostatic-fabric integrated precipitator is one of the most important factors for affecting collection efficiency. The standard k-ε turbulence model was used to simulate flow field distribution at five kinds of filtration velocity. The results show that obvious partition of flow velocity was observed, the high-speed zone was observed at the lower space of the electrostatic precipitator dust bag, the area was minimum when the filtration rate of speed was 1.6 m/min, at the same time, the filter bag narrow stream was observed at the gathering area, which the bag loading unevenness was increased. In the lower region of the bag dust, bag dust chamber area and net cross-sectional area representatives were tested. The unevenness was smallest at 0.8 m/min of filtration velocity, and areas were increasing with speed bag dust increases, but increases with height overall have shown a downward trend. |
