Abstract

An electrostatic spraying system for decontamination of a vehicle is described. The system includes a wheeled platform sized to fit inside the vehicle, at least one tank operable to contain one or more decontaminant agents, the tanks supported by said wheeled platform, a plurality of nozzles affixed to the wheeled platform, wherein each nozzle is positioned for distribution of the decontaminant agents in at least one pre-determined direction, an electrostatic charging system connected to each of the nozzles for applying an electrostatic charge to the decontaminant agents as the agents are dispersed, and at least one compressor in communication with the tanks for pressurizing the decontaminant agents. The one or more compressors are capable of providing a pressure sufficient to provide a constant distribution of the decontaminant agents through the electrostatic nozzles.

Claims

1. An electrostatic spraying system for decontamination of a vehicle, said system comprising:

a wheeled platform sized to fit inside a galley cart storage area of the vehicle;

at least one tank operable to contain one or more decontaminants, said at least one tank supported by said wheeled platform;

at least one manually operated electrostatic nozzle in communication with said at least one tank;

a plurality of automatic electrostatic nozzles attached to said wheeled platform, wherein each said automatic electrostatic nozzle can be positioned for distribution of the decontaminants in at least one pre-determined direction, wherein said plurality of automatic nozzles are configured to move in one or more dimensions to be selectively stowable within said wheeled platform as said plurality of automatic nozzles remain attached to said wheeled platform;

an electrostatic charging system connected to at least one of said at least one manually operated electrostatic nozzle and said plurality of automatic electrostatic nozzles for applying an electrostatic charge to the decontaminants as the decontaminants are dispersed; and

at least one compressor in communication with said at least one tank for pressurizing the decontaminants, said at least one compressor capable of providing a pressure sufficient to provide a constant distribution of the decontaminants through at least one of said at least one manually operated electrostatic nozzle and said plurality of automatic electrostatic nozzles.

2. The electrostatic spraying system according to claim 1 wherein at least one of said plurality of automatic electrostatic nozzles is configured to cycle through a range of motion when dispersing the decontaminants.

3. The electrostatic spraying system according to claim 1 further comprising a flowmeter in communication with at least one of said tanks, said flowmeter providing data indicative of the rate of flow from at least one of said tanks.

4. The electrostatic spraying system according to claim 1 further comprising a gauge in communication with at least one of said tanks, said gauge providing data indicative of the remaining decontaminants within at least one of said tanks.

5. The electrostatic spraying system according to claim 1 further comprising a power supply operable to supply power to at least one of said electrostatic charging system and said at least one compressor.

6. The electrostatic spraying system according to claim 1 further comprising a pressure regulator in the communications path between said tank and said compressor, said pressure regulator configured to regulate the pressure within said tank generated by said compressor.

7. The electrostatic spraying system according to claim 1, said system configured to utilize aircraft generated power to operate said electrostatic charging system and said at least one compressor.

8. The electrostatic spraying system according to claim 1 wherein said wheeled platform is sized such that it is capable of being placed within a storage area operable for storing an aircraft galley cart.

9. The electrostatic spraying system according to claim 1 wherein at least one of said at least one manually operated electrostatic nozzle and said plurality of automatic electrostatic nozzles is configured to disperse electrostatically charged droplets that range from about two microns in diameter to about forty microns in diameter.

10. The electrostatic spraying system according to claim 1 further comprising a drive system operably connected to said wheeled platform and configured to impart a motion upon said wheeled platform.

11. The electrostatic spraying system according to claim 10 wherein said drive system is configured to control a rate of motion of the wheeled platform.

12. The electrostatic spraying system according to claim 10 wherein said drive system is configured to utilize aircraft generated power.

13. The electrostatic spraying system according to claim 10 further comprising a sensor system attached to said wheeled platform and communicatively coupled to said drive system, said drive system programmed to utilize signals received from said sensor system to guide said wheeled platform along a defined path.

14. The electrostatic spraying system according to claim 1 wherein at least one of said at least one manually operated electrostatic nozzle and said plurality of automatic electrostatic nozzles is configured to be movably attached to said wheeled platform, and said at least one manually operated electrostatic nozzle is movable for stowage within said wheeled platform.

15. An aircraft decontamination system comprising:

a wheeled platform sized to fit within a galley cart storage area of an aircraft;

a canister mounted within said wheeled platform operable to contain decontaminants;

a compressor mounted within said wheeled platform operable to apply a pressure to the decontaminants within said canister;

a plurality of automatic nozzles attached to said wheeled platform and fluidly coupled to said canister, wherein each said automatic nozzle can be positioned for distribution of the decontaminants in at least one pre-determined direction, wherein said plurality of automatic nozzles are configured to move in one or more dimensions to be selectively stowable within said wheeled platform as said plurality of automatic nozzles remain attached to said wheeled platform;

an electrostatic charging system operatively attached to said automatic nozzles for applying an electrostatic charge to droplets of the decontaminants as the decontaminants are dispersed; and

a manually operated nozzle attached to said canister.

16. The aircraft decontamination system according to claim 15 wherein said manually operated nozzle is operatively attached to said electrostatic charging system.

17. The aircraft decontamination system according to claim 15 further comprising a drive system attached to said wheeled platform and configured to impart a motion upon said wheeled platform.
