FILTERING APPARATUS AND METHOD

摘要

APPARATUS AND METHOD An apparatus for removing particulate impurities froma fluid stream flowing into a bed of discrete solid elements comprising a plurality of hollow elongated basket members each adapted to be generally aligned along its longitudinal axis with the direction of fluid flow and to extend along a substantial portion of its length into the bed of solid elements, provided that at least a portion of the fluid is allowed to flow directly into the top opening of each basket member. It is essential that one-half (1/2) the average of the closest distances between closest basket members multiplied by the average longitudinal distance of the basket member sidewalls of open mesh construction in the bed of solid elements be at least about 0.75 ft.2. A method for removing particulate impurities from a fluid stream flowing into a bed of discrete solid elements is also disclosed.
