Research on the Treatment of High Concentration Dust with Bag Filter

Abstract:

Related trials in the treatment of high concentration desulfurization dust were operated in order to optimize the parameters of bag filter, established a set of data fit to semi-dry flue gas desulfurization dust, processed simulated flue gas with a concentration of SO2 600mg/m3, adopt filtration velocity between 0.63 ~ 0.98m/min, injection pressure between 0.3 ~ 0.4MPa, injection time between 200 ~ 300s. The experiments proved that the selection of the filtration velocity about the treatment of high concentrations desulfurization dust should be distinguished from the general cases. In addition, pulse pressure also should not be too high.
