摘要： A torch cutting and fume collecting enclosure is disclosed that is particularly adapted for the collection of lead-containing fumes and gases emitted during cutting of steel strands. The enclosure comprises a plurality of walls and two flexible barriers disposed on opposite ends of the enclosure, one at a receiving end, and the other at an output end of the enclosure. The enclosure further comprises a unique air handling system comprising one or more collector hoods, ducts and plenums for collecting and moving air and other gas flows from the enclosure for subsequent treatment and/or discharge. The air handling system utilizes a unique tapered configuration for one or more plenums that reduces the tendency for particulates to separate from an air or gas flow.
