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.
