Abstract
An apparatus and method for removing particulate from a particulate-laden gas stream are disclosed. The apparatus and method include a reverse-flow process for cleaning filter bags with a cleaning gas stream. The process includes: flowing a particulate-laden gas stream to one side of the filter bags; stopping the particulate-laden gas stream to at least one filter bag; popping the filter bag with a reverse-flow of a cleaning gas stream to remove dust from the bag; and finally re-introducing the particulate-laden gas stream to the recently cleaned filter bag at a low velocity/flow rate to prevent small particles from blowing through the recently cleaned filter bag. The apparatus and method allow the particulate-laden gas stream and cleaning gas stream to be controlled independently.
