Abstract
The present invention is a combined gas flow resistance device and safety shield which incorporates a plurality of narrow parallel passageways through which filtered gas from a plurality of filter elements passes to a clean gas outlet. The device also has inlet for carrying pulses of high pressure gas to the downstream side of a plurality of filter elements, and a porous safety shield connected across the passageways to prevent solid particles from passing from the filter elements to the clean gas outlet.
Claims12
A gas flow resistance device for resisting the flow of gas from the downstream side of a plurality of filter elements connected between a gas inlet and a gas outlet, comprising in combination
- a body formed of a refractory material,
- a first plurality of parallel, narrow passageways extending through said body, and
- a first porous safety shield mounted across one end of said first plurality of parallel narrow passageways for preventing solid particles from travelling between said filter elements and said gas outlet.
