Abstract
A method and apparatus for the containment of dust within a bulk cargo container such as a ship or barge hold. A horizontal stream of ambient air is directed across the hatch opening by a plurality of interconnected air curtain modules which captures fugitive dust along its path. A plurality of interconnected dust collector modules withdraw the entrained dust particles at an opposite side of the hatch opening and exhaust the filtered air stream therefrom and deposit the filter cake back into the hold. The clean exhaust air from the dust collector modules may be used to form a vertical air curtain to deflect crosswinds.
