1. A proppant storage device for use with a hydraulic fracturing system; said proppant storage device comprising a proppant dust catcher at least partially enclosed by said proppant storage device:
I) said proppant storage device further comprising:
a) a bed capable of directing proppant away from said proppant storage device;b) a plurality of outer generally vertical walls;c) a roof comprising one or more doors, wherein a combination of said bed, said outer generally vertical walls and said roof create a holding chamber for proppant;d) one or more inner vertical walls subdividing said holding chamber into sections; ande) a connection with a source of pneumatic energy supplying proppant and pressure to said holding chamber; and II) said proppant dust catcher comprising:
a) a plurality of conduits positioned proximate an inward side of said roof and connected with ports to an environment external to said proppant dust catcher; each said conduit spanning above said proppant contained in each said section and comprising holes allowing air flow between said holding chamber and said conduits moving air flow between said holding chamber and said environment external to said proppant dust catcher, wherein when said pneumatic energy is supplied to said holding chamber, said pressure forces air through said holes; andb) a filter proximate each of said conduits including said holes, wherein said filter is positioned between said holes and said sections for catching proppant dust prior to entry into said holes. |
