Abstract

Abstract

In this paper, in order to obtain the law of the influence of relative position of the baffles and the inlet and outlet on the air flow distribution in the bag filter, under the condition of higher negative pressure and higher inlet wind speed, the air flow distribution in the composite bag filter under four different boundary conditions were studied through the CFD numerical simulation method. The results were as the follows: the overall uniformity of flue gas treatment capacity was better when the relative position of air inlet and air outlet was 90°; the guide plate arranged at the lower part of the filter bag, which could not only avoid the impact of activated carbon particles on the filter bag, but also make the overall distribution of the flue gas treatment capacity of the filter bag more uniformed; the closer the filter bag was to the edge of the precipitator, the greater the flue gas treatment capacity was because of the inlet jet effect. This research provided a reference for further optimizing the structure of composite bag filters.
