Abstract

A deicing fluid recovery system includes a vehicle movable adjacent to an aircraft and including a holding tank configured to store deicing fluid and a receptacle configured to capture deicing fluid from the aircraft during a deicing procedure. During the deicing procedure, deicing fluid runoff from a surface of the aircraft may be captured into the receptacle and transferred from the receptacle into the holding tank. The deicing fluid runoff may be captured into the receptacle before the deicing fluid runoff contacts ground.

Claims

1. A deicing fluid recovery system, comprising:

a vehicle movable adjacent to an aircraft, the vehicle including;

a holding tank configured to store deicing fluid; and

a receptacle configured to capture deicing fluid from the aircraft during a deicing procedure and transfer the deicing fluid into the holding tank, such that deicing fluid runoff from the aircraft is captured into the receptacle before the deicing fluid runoff contacts ground.

2. The deicing fluid recovery system according to claim 1, further comprising a boom lift movable from a first position to a second position relative to the vehicle, the boom lift having a first end portion secured to the vehicle, and a second, articulating end portion secured to the receptacle, wherein movement of the second, articulating end portion of the boom lift causes a corresponding movement of the receptacle.

3. The deicing fluid recovery system according to claim 1, further comprising:

a pump having an first port and a second port, the second port in fluid communication with the holding tank; and

a fluid line having a first end portion and a second end portion, the first end portion of the fluid line in fluid communication with the receptacle, the second end portion of the fluid line in fluid communication with the first port of the pump, wherein the pump is configured to suction, through the fluid line, deicing fluid from the receptacle into the holding tank, and wherein the pump is configured to discharge deicing fluid from the holding tank into the receptacle.

4. The deicing fluid recovery system according to claim 3, wherein the receptacle includes a spray ring having a plurality of nozzles, and wherein the first end portion of the fluid line is in fluid communication with the spray ring.

5. The deicing fluid recovery system according to claim 3, further comprising a second tank in fluid communication with the holding tank, the second tank configured to receive deicing fluid from the holding tank.

6. The deicing fluid recovery system according to claim 5, further comprising:

a second pump including an inlet port and an outlet port, the inlet port of the second pump in fluid communication with the holding tank and the second tank; and

a discharge line having a first end portion and a second end portion, the first end portion of the discharge line in fluid communication with the outlet port of the second pump, the second end portion of the discharge line in fluid communication with a spray ring of the receptacle, the spray ring having a plurality of nozzles, wherein the inlet port of the second pump is configured to suction deicing fluid from the second tank, and wherein the outlet port of the second pump is configured to discharge deicing fluid, through the discharge line into the spray ring, and through the plurality of nozzles of the receptacle.

7. The deicing fluid recovery system according to claim 1, wherein the receptacle defines an inner surface and an outer surface, the receptacle having a drain defined through the respective inner and outer surfaces.

8. The deicing fluid recovery system according to claim 7, wherein the inner surface of the receptacle includes at least one of barbs, spikes, and protrusions.

9. The deicing fluid recovery system according to claim 7, wherein the receptacle includes at least one of a filter and a mesh disposed over the drain.

10. The deicing fluid recovery system according to claim 1, wherein the receptacle includes at least one sensor configured to detect at least one of an overflow within the receptacle, an obstruction inside of the receptacle, and an obstruction outside of the receptacle.

11. The deicing fluid recovery system according to claim 10, wherein the sensor is selected from the group consisting of passive infrared, proximity, contact, microwave, magnetic reed-switch floats, solid state electro optical, and visual level indicators.

12. The deicing fluid recovery system according to claim 1, wherein the receptacle is formed from a material selected from the group consisting of metal, ceramic, plastic, polymer, wood, and composite.

13. The deicing fluid recovery system according to claim 1, wherein the receptacle defines a semi-spherical shape, the receptacle having a flange extending outwardly from a perimeter thereof, the flange configured to enlarge a surface area of the receptacle for capturing deicing fluid.

14. The deicing fluid recovery system according to claim 1, wherein the vehicle is selected from the group consisting of a car, truck, ATV, airport ground support vehicle, automated guided vehicle, and utility vehicle.

15. A method for recovering deicing fluid during an aircraft deicing procedure, comprising:

spraying an aircraft with deicing fluid;

positioning a vehicle and a receptacle of the vehicle under a location of deicing fluid runoff from the aircraft; and

capturing the deicing fluid runoff into the receptacle before the deicing fluid runoff contacts ground.

16. The method according to claim 15, further comprising pumping deicing fluid from the receptacle through a fluid line into a holding tank, the holding tank being secured to the vehicle.

17. The method according to claim 16, further comprising pumping deicing fluid from the holding tank into the receptacle.

18. The method according to claim 17, further comprising spraying deicing fluid into a spray ring of the receptacle and through a plurality of nozzles disposed on an inner surface of the receptacle to clear an obstruction within the receptacle.

19. The method according to claim 15, further comprising:

activating a boom lift of the vehicle, the boom lift having a first end portion secured to the vehicle, and a second, articulating end portion secured to the receptacle; and

moving the second, articulating end of the boom lift to cause a corresponding movement of the receptacle.

20. The method according to claim 15, further comprising repositioning the vehicle if a location of the deicing fluid runoff from the aircraft has changed.
