PORTABLE VACUUMING DEVICE FOR COLLECTING AND NEUTRALIZING FLAMMABLE RESIDUE

摘要

A vacuuming device for neutralizing flammable powders. The device includes a container having an upper chamber and a lower chamber separated by a baffle, with the upper chamber being in fluid communication with the lower chamber proximate an outer annular region of baffle. A liquid such as water is disposed in the lower chamber, and an air jet drawn into the lower chamber via a vacuum inlet line. In one embodiment, the air jet passes through the liquid for generation of a tangential flow that causes the body of liquid to rotate within the lower chamber. The rotation in the lower chamber can also cause the air in the upper chamber to rotate, so that liquid droplets entrained therein migrate to the outer wall centrifugally. Flammable particles entrained in the air jet are wetted and neutralized.

主权项

1. A portable vacuuming device for neutralizing flammable powders, comprising:
a container including a top portion, a bottom portion, and a sidewall portion that separates said top portion and said bottom portion, said container defining an interior chamber; a baffle disposed in said container and suspended over said bottom portion of said container; a vacuum inlet line in fluid communication with said interior chamber, said vacuum inlet line defining an egress port, said egress port being disposed between said baffle and said bottom portion of said container, said egress port being arranged for generation of a tangential flow component that is parallel to a face of said sidewall portion; and a suction source in fluid communication with said interior chamber of said container.
