Filtering system and method of using same

摘要

A filter system wherein a hollow tubular member having an imperforate wall with a plurality of slots therein is coaxially positioned within a perforated mandrel that supports a ceramic bag filter. Gases to be filtered pass through the bag filter and deposit particulate matter thereon, enter a chamber between the perforated mandrel and the hollow tubular member, and are directed through the slots into the interior of, and are discharged from an open end of the hollow tubular member. Vapor phase contaminants in the gas can also be removed by providing a bed of solid absorbent material in the hollow tubular member such that the gas contacts the solid absorbent material and the vapor phase contaminant is removed prior to discharge of the gas from the open end of the hollow tubular member.
