Abstract
A filter material charging apparatus for adding a gas treating material into gas treating cells contained in a filter housing includes an open bottomed gas treating material conveying channel and air evacuation conduits located in the filter housing over the gas treating cells. Air-borne filter material is delivered to the conveying channel from a source outside the filter housing. Baffles are located in the channel to distribute gas treating material over the length and breadth of the filter housing, and into the gas treating cells as the gas treating material exits the channel through its open bottom. The air which carried the filter material into the housing is evacuated from the interior of the filter housing by the air evacuating conduit.
Claims23
A charging apparatus for adding a gas treating material into open topped gas filter cells contained in a filter housing, the charging apparatus comprising:
- gas treating material conveying elongated channel means disposed within the housing and spaced above the gas filter cells, the gas treating material conveying elongated channel means having an open bottom which faces downwardly toward the open tops of the gas filter cells;
- means for directing at least a portion of the gas treating material generally directly downwardly out of the open bottom of the gas treating material conveying elongated channel means;
- and,
- means for directing at least a portion of the gas treating material generally laterally outwardly of the open bottom of the gas treating material conveying elongated channel means after said means for directing at least a portion of the gas treating material generally directly downwardly becomes blocked by gas treating material deposited beneath it.
