Abstract:
1. A gasoline-ethanol separation apparatus for separating a mixture fuel formed of mixed gasoline and ethanol into gasoline and an ethanol-water mixture liquid by mixing water with the mixture fuel, comprising: a fuel tank for accommodating the mixture fuel; water-supply means for supplying water to be mixed into the mixture fuel; a separation tank which separates the mixture fuel into the gasoline and the ethanol-water mixture liquid by mixing water supplied by the water-supply means with the mixture fuel supplied from the fuel tank, and stores the separated gasoline and the ethanol-water mixture liquid therein; a flow-path-forming member having an inner circumference with through holes located within the separation tank, the flow-path-forming member changing a direction of gasoline and ethanol-water mixture liquid moving in the separation tank; pressurizing means for pressurizing the gasoline and the ethanol-water mixture liquid stored in the separation tank through the mixture fuel to be supplied from the fuel tank into the separation tank; gasoline-taking-out means for taking the gasoline out from an upper part of an interface between the gasoline and the ethanol-water mixture liquid stored in the separation tank to the outside of the separation tank through a first on-off valve; and ethanol-taking-out means for taking the ethanol-water mixture liquid stored in the separation tank out from a lower part of the interface from within the inner circumference of the flow-path-forming member to the outside of the separation tank through a second on-off valve.
