ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates-to the evacuation of hazardous and/or harmful vapors from a tanker vehicle. These vapors are typically vented into the atmosphere where they can cause environmental problems, or stored in the tanker vehicle where they can pose a danger, especially if they are flammable and/or volatile.
OBJECTS OF THE INVENTION
One object of the invention is to provide a vapor evacuation device that can evacuate vapors from tanker vehicles.
Another object of this invention is to provide a vapor evacuation device which combines harmful vapors into an easily disposable liquid and/or air stream.
Still another object of the invention is to provide a vapor evacuation device which is portable.
Still another object of the invention is to provide a vapor evacuation device that is able to recycle the water used to evacuate the vapors.
Other objects and advantages of this invention shall become apparent from the ensuing descriptions of the invention.
SUMMARY OF THE INVENTION
According to the present invention, the vapor evacuation device comprises at least one fluid line which can have a pump configured to draw a water and/or air mixture which is combined with vapors vacuumed from a tank via another inlet, yielding a solution that can then be disposed as a liquid. Vacuum at the inlet is created by the flowing of the water or air/water mixture past the inlet. The reduced pressure of the moving, liquid causes a pressure differential with the higher pressure within the tank, and thus the vapors migrate into the vapor evacuation assembly, are mixed with the fluid, and can then be disposed, or continually recycled, with the fumes stored for later disposal.
