ABSTRACT:
For purposes of maintaining equipment in enclosures which generate noxious fumes, such as in connection with the handling of sewage in a lift station, there must be adequate venting means to permit entry of workmen into the enclosure without the need of gas masks. In the present integrated system, auxiliary vent capacity is provided through the use of extra fan means and at least one bed of fume absorbent material. This auxiliary fume removal, which can be switched into and out of operation, together with a catalytic or thermal fume treating section, will provide for an arrangement where the absorbent material can be used during temporary periods of venting and then subjected to a reverse out-to-in flow so that desorbed fumes will be treated in the fume incinerator section so that the absorbent material becomes regenerated for reuse at a subsequent time period.
