1. An environmentally-friendly exhaust device, comprising:
an outer tank, a plurality of supporting legs being disposed on a bottom circumference of the outer tank, a fixing block being disposed on a central location inside the outer tank, an upper connecting hole being disposed on a central location of a top side, a lower connecting hole being disposed on a central location of a bottom side, the upper connecting hole and the lower connecting hole being connected, a guiding groove portion being disposed on a bottom of the fixing block, a stopping plate being disposed on two sides of the fixing block respectively, a pivot being disposed in the upper connecting hole of the fixing block, a middle section of the pivot being formed with a relatively larger diameter for the pivot to press against inside the upper connecting hole, an axial hole being penetrated through a central location of the pivot, an axial rod being disposed in the axial hole, a bottom end of the axial rod being formed with a relatively smaller diameter, the bottom end of the axial rod pressing against the lower connecting hole after penetrating through the axial hole, a top end of the axial rod penetrating through the axial hole, a locking piece being sleeved on the top end of the axial rod, the locking piece being fixed on a top side of the pivot, a plurality of rotational rods being disposed radially on a circumference of the locking piece, an air propeller being disposed on an end portion of each of the rotational rods, a plurality of inclined guiding grooves in spiral grooved shape being disposed on the circumference of the locking piece, each of the guiding grooves extending downwardly to a bottom end of the pivot, an oil outlet being connected to a lower section of the outer tank, a water outlet being connected to the outer tank below the oil outlet, an oil outlet switch being disposed on the oil outlet, a water outlet switch being disposed on the water outlet, a water outlet pipe being connected to a bottom central location of the outer tank, a first water outlet switch being disposed on the water outlet pipe for controlling the water outlet pipe to let out water; an inner pipe disposed inside the outer tank, a fixing frame being disposed on a bottom end inside the inner pipe, the fixing frame being disposed on the top end of the axial rod for positioning the inner pipe, a filter screen assembly being disposed inside the inner pipe and above the fixing frame, the filter screen assembly comprising multiple layers of separated arc-shaped screens, a plurality of connecting rods being disposed on an inner circumference of each of the arc-shaped screens for connecting the arc-shaped screens as one body, an arc-shaped part of each of the arc-shaped screens facing upwardly or facing downwardly, each of the connecting rods extending upwardly and bending to connect with each other for convenience of holding, a circular stopping plate being disposed on an outer circumference of an upper section of the inner pipe, a circumference of the circular stopping plate being fixedly connected to an inner circumference of the outer tank, an upper guiding plate being connected to a lower edge of the circular stopping plate on the inner pipe, the upper guiding plate being spirally surrounding on the inner pipe and fixedly connected to an inner surface of the outer tank, a lower guiding plate being disposed below the upper guiding plate, the lower guiding plate being fixedly connected to the inner surface of the outer tank, a compartment being formed between the lower guiding plate and the upper guiding plate for spirally surrounding on the inner pipe, a double spiral with a helix intersecting shape being formed by the upper guiding plate and the lower guiding plate; a water spray device comprising a tubular portion, an end of the tubular portion being connected to the outer tank and the tubular portion being disposed between the upper guiding plate and the lower guiding plate, another end of the tubular portion being connected to an air inlet pipe, the air inlet pipe being used for transporting air and oil mist, the air and oil mist inside the air inlet pipe being guided between the lower guiding plate and the upper guiding plate and flowed downwardly to the bottom of the outer tank, a mist sprayer being disposed inside the tubular portion for spraying mist toward the outer tank, the mist sprayer penetrating through the tubular portion upwardly for connecting with a mist spray elastic switch, the mist spray elastic switch being used for controlling the mist sprayer to spray mist, the mist spray elastic switch being connected with a water controlling element for controlling inlet and outlet of a water source, an actuating portion being pivotally disposed on an upper circumference of the tubular portion, the actuating portion being disposed between the mist spray elastic switch and the outer tank, the actuating portion being pressed toward the mist spray elastic switch, the actuating portion being connected to an actuating plate disposed inside the tubular portion, the actuating plate being blown and moved by a wind power inside the air inlet pipe for pressing the actuating portion toward the mist spray elastic switch and causing the mist sprayer starting to spray mist, the mist spray elastic switch being automatically restored and stopped to spray mist after the wind power disappearing; a lower cover comprising a lower body with a concave arc-shaped top, a lower sleeve portion being disposed on a central location of a bottom of the lower body, the lower sleeve portion being sleeved on the outer circumference of the inner pipe; an upper cover comprising an upper body with a concave arc-shaped bottom, an upper sleeve portion being disposed at a central location of a top of the upper body, a circumference of the upper body being connected to a top end edge of the outer tank; an oil and water separating tank connected to the oil outlet and the water outlet, a water discharge portion being disposed on a lower section of the oil and water separating tank, an oil storage pipe being connected on the oil and water separating tank, and an oil discharge portion being disposed on the oil storage pipe. |
