  • Filtering Of Dispersed Particles In Gases (AREA)

Abstract

PURPOSE: To obtain a high dust collecting performance at the seperation and removal of solids suspending in gas while passing through a granular filtrating layer movable by its gravity, by stopping the granular layer to move when the head loss caused by the gas flow is lower than a prescribed level, and moving the layer when the head loss is higher than said level, and by repeating this controlling means.
CONSTITUTION: At the separation and removal of solids suspending in gas by filtrating the gas through a granular filtrating layer movable by the gravity of the granules; the layer is left stationarily when a head loss caused by a gas flow is lower than a prescribed head loss level previously fixed; and when the head loss is higher than said level, the layer is moved by a prescribed time. By repeating these operations, a time to form a cake of the dust on the surface of the filter layer, a time of preparing for a new space by moving the layer together with a time for stripping a piled up dust from the filter surface are secured.
