System for removing and collecting dust particles
Embodiments of the present disclosure describe a system for capturing dust and dust-laden air caused by the agitation, movement or transfer of particulate material. The system includes a dust collection assembly positioned proximate and associated with the delivery of particulate material to capture dust particles released by movement and settling of the particulate material when being dispensed and delivered. The dust collection assembly is positioned to direct an air flow in a flow path overlying the dust particles to capture the dust particles and move the dust particles away from the proppant thereby reducing risk of dust exposure.
1. A system for capturing dust particles while minimizing the capture of usable proppant, the system comprising:
a hood assembly in fluid communication with a delivery chute;
a dust receptacle coupled to the hood assembly, the dust receptacle in fluid communication with a duct configured to provide suction to the hood assembly;
an upstream de-dusting encasement affixed to the hood assembly, the upstream de-dusting encasement coupled to the delivery chute, the upstream de-dusting encasement sized and shaped to match a geometry of the delivery chute;
a diffuser screen coupled to the upstream-de-dusting encasement upstream of the hood assembly; and
a de-dusting air-intake coupled to the upstream de-dusting encasement configured to produce suction upstream of the hood assembly separating the dust particles from the usable proppant in the upstream de-dusting encasement.
2. The system of claim 1 further comprising a pick-up shaped to match the geometry of the delivery chute and affixed to the hood assembly, the pick-up extending upstream of the hood assembly.
3. The system of claim 2 further comprising the diffuser screen disposed on an upstream facing wall of the pick-up.
4. The system of claim 1 wherein the de-dusting encasement is coupled to the delivery chute by a plurality of straps extending around the delivery chute.
5. The system of claim 1 wherein the de-dusting encasement is coupled to the delivery chute by a plurality of clamps.
6. The system of claim 1 wherein the fastener comprises the de-dusting encasement is coupled to the delivery chute by a supporting bracket.
7. The system of claim 1 further comprising a flexible curtain affixed to a lower portion of the hood assembly.
8. The system of claim 7 wherein the flexible curtain extends partially around a perimeter of the lower portion of the hood assembly.
9. The system of claim 1 further comprising a flexible curtain affixed to a rear, lower portion of the hood assembly.
10. The system of claim 1 further comprising an auxiliary suction hood coupled to the hood assembly, the auxiliary suction hood in fluid communication with the duct.
11. The system of claim 1 further comprising a collector in fluid communication with the dust receptacle.
12. The system of claim 11 wherein the duct establishes fluid communication between the dust receptacle and the collector.
13. The system of claim 1 wherein the duct comprises a plurality of vents.
14. The system of claim 13 wherein the vents are disposed on a top side and on first and second opposing sides of the upstream de-dusting encasement.
15. The system of claim 13 wherein the vents are adjustable.
16. A dust collection assembly for collecting dust-laden air produced by agitation of a particulate material, the dust collection assembly comprising:
a hood assembly in fluid communication with a delivery chute;
a dust receptacle coupled to the hood assembly, the dust receptacle in fluid communication with a duct configured to provide suction to the hood assembly;
an upstream pick-up affixed to and extending upstream from the hood assembly, an upper portion of the upstream pick-up sized and shaped to match an internal geometry of the delivery chute, the upstream pick-up comprising a diffuser screen in an upstream-facing wall;
an air intake in fluid communication with the upstream pickup configured to produce suction upstream of the hood assembly separating the dust-laden air from the particulate material in the upstream pickup;
a receiving fastener affixed to the hood assembly and configured to receive and secure the delivery chute to the hood assembly.
17. The dust collection assembly of claim 16 further comprising a curtain affixed to a perimeter of a lower portion of the hood assembly.
18. The dust collection assembly of claim 16 further comprising a flexible curtain affixed to at least one side of a lower portion of the hood assembly.
