DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Referring to FIG. 1, a quick purification device for smoke and exhaust gas discharged from a engine, in a preferred embodiment of the present invention, includes a communicating tube 12, the axial direction of which is vertically arranged, and the upper end of which is configured with a necked portion 13, first flared portion 14, second flared portion 15 and exhaust tail pipe 17 in sequence from bottom to top, where the second flared portion 15 is configured in such a way as to be inverted with respect to the first flared portion 14 to make the ends of the largest diameter thereof opposite to each other. Furthermore, a plurality of straight-through ceramic filters 2 are configured between the first flared portion 14 and second flared portion 15, allowing both the ends of the largest diameter thereof to face it. Furthermore, a waste water diversion tube 121 is connected to the lower end of the communicating tube 12, and an exhaust vent 171 facing upward is opened on the top end of the exhaust tail pipe 17. Furthermore, an air inlet pipe 1, which has an air inlet 11 adapted to be in connection with an exhaust outlet of a marine engine, is linked to the communicating tube 12 between the necked portion 13 and waster diversion tube 121.

[0019] Furthermore, in the preferred embodiment, a multi-hole mesh screen 16 is configured on the upper end of the first flared portion 14, allowing the straight-through ceramic filters 2 to be supported by the mesh screen 16 but not to affect the flowing smoothness of air flow.

[0020] In the embodiment, the communicating tube 12 between the necked portion 13 and air inlet 1 is configured with a first exhaust gas flushing device 3A, which includes a plurality of atomizing nozzles 31 arranged around the inner circumference of the communicating tube 12, the orifice of each of which is directed toward the center of the communicating tube 12, where the first exhaust gas flushing device 3A, through piping, is connected to a pump (not shown in the figure) capable of pumping fluid (seawater) to each atomizing nozzle 31, allowing it to spray the pumped fluid (seawater) into the inside of the communicating tube 12.

[0021] In the embodiment, the communicating tube 12 on the upper end of the second flared portion 15 is configured with a second exhaust gas flushing device 3B, which includes a plurality of atomizing nozzles 31 arranged around the inner circumference of the communicating tube 12, the orifice of each of which is directed toward the center of the communicating tube 12, where the second exhaust gas flushing device 3B, through piping, is similarly connected to a pump (not shown in the figure) capable of pumping fluid (seawater) to each atomizing nozzle 31, allowing it to spray the pumped fluid (seawater) into the inside of the communicating tube 12.

[0022] Furthermore, in the embodiment, the exhaust outlet 17 above the second exhaust gas flushing device 3B is configured with a third exhaust gas flushing device 3C, which includes a plurality of atomizing nozzles 31 arranged around the inner circumference of the exhaust tail pipe 17, the orifice of each of which is directed toward the center of the exhaust tail pipe 17, where the third exhaust gas flushing device 3B, through piping, is similarly connected to a pump (not shown in the figure) capable of pumping fluid (seawater) to each atomizing nozzle 31, allowing it to spray the pumped fluid (seawater) into the inside of the exhaust tail pipe 17.

[0023] The operation manner of the quick purification device for smoke and exhaust gas discharged from a marine engine of the present invention is connecting air inlet pipe 1 to the exhaust outlet of a marine engine. Upon the sailing of a ship, highly heated exhaust gas will flow upward (hollow arrows as shown in the figure) after entering the communicating tube 12 from the air inlet 1. At the same time, each atomizing nozzle 31 of the first exhaust flushing device 3A sprays fluid (sea water) to carry out primary flushing to the exhaust gas, and the flushed exhaust water drops downward (solid arrows as shown in the figure) and is discharged from the exhaust diversion tube 121. Thereafter, the primarily flushed exhaust gas flow upward continuously to pass through the necked portion 13 and first flared portion 14 to be speeded to pass through the straight-through ceramic filters 2 and second flared portion 15. And then, the exhaust gas passes through the second, third exhaust gas flushing devices 3B, 3C in sequence, and at the same time, the atomizing nozzles 31 thereof also spray fluid (seawater) to carry out second and third flushing processes to the exhaust gas to flush out contaminants; the flushed exhaust water will drop downward, and the dropped exhaust water will flush down carbon particles accumulated inside the straight-through ceramic filters 2 while passing through them, allowing the contaminants to be discharged out with the exhaust water through the communicating tube 12 and water gas diversion tube 121. As a result, the exhaust gas passing through the second, third exhaust gas flushing devices 3B, 3C can then be purified, and the purified exhaust gas flows upward continuously, being discharged out from the exhaust vent 171 of the exhaust tail pipe 17.
