Blasting fluid effluent containment device
DCFirst Claim
1. A blasting fluid effluent containment device, comprising:
- a containment bag, including;
a wall enclosing an interior space, anda throat having a leading edge defining a circular opening to accommodate an open end of a vessel;
a flange strap to secure the throat to the vessel and seal the interior space;
at least one support band, encircling the interior space, to support the containment bag in an expanded condition;
at least one attachment point, connected to the support band, to suspend the containment bag; and
a drain port.

Abstract
A device is disclosed which acts to contain the contaminated effluent of an operation such as a hydro-blasting operation. The device has flexible bag for containing the effluent. The bag has an opening interfacing with a vessel being fluid blasted, into which opening the blasting effluent is received. A drain port is positioned on the containment bag to gravity empty the effluent from the interior of the bag, and a vent appropriately located on the containment bag to relieve pressure in the interior space during use and emptying. A flange strap disposed secures the bag opening to the vessel, and a support means is arranged to suspend the containment bag in proper relationship with the vessel. An expansion mechanism can be used to hold the containment bag in an expanded condition to facilitate use of the bag to properly contain the effluent.

16. A method for containing blasting fluid effluent from a vessel using a containment device that includes a containment bag, a flange strap, at least one support band, at least one attachment point connected to the support band, and a drain port, the containment bag including a wall enclosing an interior space and a throat having a leading edge defining a circular opening to accommodate an open end of the vessel, the support band encircling the interior space, the method comprising:
-
passing the throat over a flange of the open end of the vessel; tightening the flange strap to closely engage the throat around the flange and to seal the interior space to the vessel; suspending the containment bag using the attachment point; receiving the blasting fluid effluent; and emptying the blasting fluid effluent from the interior space. - View Dependent Claims (17, 18)
