Abstract

An apparatus and method for collection of particulate matter includes a plenum chamber formed in an funnel or a frustum configuration that discharges into a distribution chute assembly. The distribution chute assembly includes a number of individual chutes, each equipped with a circular collar or collar groove at the outlet which facilitates the attachment of the cylindrical dust collection sacks. The plenum chamber, distribution chute assembly, and individual dust collection sacks are carried by a frame assembly.

First claim

What is claimed:

1. A method for the collection of particulate matter, comprising:
providing a dust collection apparatus having a plenum chamber with an upper inlet and a lower end fluidly connected to first, second, and third chutes disposed at an angle of about 15-60 degrees with respect to vertical, respectively;
connecting first, second, and third bags to lower ends of said first, second, and third chutes, respectively;
connecting a duct to said inlet;
conducting fracturing operations at a hydrocarbon well site;
collecting airborne proppant dust at said well site from said fracturing operations;
providing said collected airborne proppant dust to said dust collection apparatus via said duct; and
flowing the proppant dust from the plenum chamber through the first, second and third chutes into the first, second and third bags through the first, second and third chutes.

2. The method of claim 1 further comprising:
distributing said proppant dust into said first, second, and third bags by said plenum chamber.

3. The method of claim 1 further comprising:
carrying said dust collection apparatus atop a frame.

4. The method of claim 3 further comprising:
carrying said frame atop a plurality of wheels; and
rolling said dust collection apparatus from a first location to a second location.

5. The method of claim 1 further comprising:
removably attaching said first, second, and third bags to said first, second, and third chutes, respectively.

6. The method of claim 1 further comprising:
providing a fourth chute that is fluidly connected to said lower end of said plenum chamber; and
connecting a fourth bag to said fourth chute.

7. The method of claim 1 further comprising:
lowering said first, second, and third chutes to facilitate attachment of said first, second, and third bags;
raising said first, second, and third chutes as said first, second, and third bags become filled with said proppant dust; and
raising said first, second, and third chutes to facilitate removal of said first, second, and third bags.
