Definitions

  • the present invention relates, generally, to dust suppression systems, and more particularly the use of electrostatically charged water particles sprayed on dust particles generated by moving vehicles.
  • Mining and construction operations currently control fugitive dust that is generated by mobile equipment sources, such as heavy truck, earth moving equipment, and similar vehicles, by using chemical stabilization products or water sprays from tank trucks.
  • chemical stabilization products can be sprayed onto mining or construction road surfaces, or blade mixed into the soil at weekly or monthly intervals.
  • Using chemical stabilization products is disadvantageous and costly because, for example, it often requires repeat application after rainfalls which wash the product away, and the chemical constituents may interfere with mineral processing reagents during certain mining operations.
  • a preferred application of the present invention is in mining and construction fields; however, it should be appreciated that the subject invention is not limited to those applications.
  • liquids such as water can be atomized by spray nozzles or similar atomizing devices, and the atomized liquids can be inductively charged by passing a spray of atomized liquid particles through a ring which is maintained at some potential relative to the atomizing apparatus. It is also known that particles of fugitive dust carry a small electrical charge. See, for example, Hoenig, Russ, and Bidwell, "Application of Electrostatic Fog Techniques To The Control of Respiratory Particulates," published by the Department of Electrical Engineering, University of Arizona, dated April 1 6, 1 976, and revised May 1 , 1 976.
  • the present invention addresses these disadvantages of prior methods for controlling dust from moving sources by providing a system for spraying electrostatically charged water droplets onto dust particles generated by the moving source.
  • the system is suitably mounted on the moving dust source, e.g. a mine haulage truck, and enables water to be pumped through atomizing spray nozzles which atomize the water into droplets and add an electrostatic charge to droplets as they are discharged onto an area of fugitive dust behind a moving vehicle.
  • the electrostatically charged water droplets become attracted to dust, causing the dust particles to agglomerate and fall out of the atmosphere due to gravitational forces, thus less water tends to be required to enable suppression of the dust, such as, for example, may be used with conventional water tank trucks.
  • the system comprises a water tank, a water pump, and a plurality of electrostatically charged water spray nozzles, all connected by an appropriately placed network of pipes, hoses, and valves and mounted on a production vehicle, such as a mine haulage truck.
  • a power transformer or, alternatively, an electrical generator mounted on the vehicle.
  • the transformer converts conventional truck battery or generator power into a power source that is connected via a wiring network to the spray nozzles and provides the power for the water pump and for the electrostatic charge that is imparted to the atomized water droplets. If an independent electrical generator is used, it produces electrical power which is provided to the water pump and the electrostatic charge.
  • the system also includes an air compressor and an air pump both of which are connected to the spray nozzles, thus enabling enhancement of the atomization and spraying process.
  • a control panel is optimally connected to the water pump, air compressor, and spray nozzle control valve to provide for both manual and automatic activation of the spraying system.
  • the control panel is also connected to the speed measuring mechanism of the production vehicle upon which the system is mounted and uses the vehicle's speed to automatically activate and/or increase or decrease the rate of water dispersion as a function of the speed of the vehicle.
  • Figure 1 is a schematic side view of a preferred exemplary embodiment of a dust suppression system in accordance with the present invention as installed upon a vehicle, such as a haulage truck;
  • Figure 2 is a top view of a preferred truck and spray system design, in this view with the bed of the haulage truck removed;
  • Figure 3 is a schematic back view of a preferred truck device also with the truck bed removed;
  • Figure 4 is a schematic lay out of a preferred embodiment of an operator monitor and control panel useful in connection with a dust suppression system in accordance with the present invention
  • Figure 5 is a system schematic of a control system useful in connection with a preferred dust suppression system, such as that shown in Figures 1 -4; and,
  • Figure 6 is a side view of a preferred spray gun useful in connection with the dust suppression system of the present invention.
  • the subject matter of the present invention is particularly suited for use in connection with mining, construction, farming and/or military operations.
  • a preferred exemplary embodiment of the present invention will be described in the context of a haulage truck of the type commonly used in connection with mining operations. It should be recognized that this description is not intended as a limitation on the use or applicability of the subject invention but rather serves to merely describe a preferred embodiment thereof. As a result, in connection with this description, the term "vehicle" will be used to describe the illustrated haulage truck.
  • the subject matter of the present invention is suitable for broad application to a variety of mobile vehicles which may be used in environments creating dust or other particulate contaminants to be created as a result of the vehicles movement.
  • applications in the agricultural, construction, tractor trailer and military context are also contemplated as being within the subject matter of the present invention.
  • vehicle should be understood to refer to the various vehicles which can be used in these environments, such as loaders, dozers, graders, scrapers, excavators, tanks, people movers, plows, harvesting machinery (e.g. bailers, fertilizing equipment, spreaders, combines, etc.), long wall mining equipment, haulage trucks, tractor trailers, street sweepers and the like.
