摘要 |
A method and apparatus for efficient removal of particulates from a gas is described which incorporates a barrier filter (44) (e.g. baghouse) internally of an electrostatic precipitator (34). An alternative embodiment is disclosed which incorporates an electrostatic precipitator (34) and a barrier filter (44) (i.e. baghouse) in series, with a pre-charger (40) interposed therebetween. The series arrangement enables the barrier filter (44) to operate at significantly higher filtration velocities than normal 4.06-20.32 cm/s (8-40 ft/min) versus 0.76-2.54 cm/s (1.5-5 ft/min) and reduces the size of the barrier filter (44) significantly. The pre-charger (40) adds an additional electrostatic charge to particulates exhausted from the electrostatic precipitator (34) and replaces charge lost in lengthy and poorly insulated conduits.
