Quick purification device for smoke and exhaust gas discharged from marine engine

Abstract

A quick purification device for smoke and exhaust gas discharged from a marine engine includes a vertical communicating tube, a necked portion, first flared portion, second flared portion and exhaust tail tube are formed on the top end of the communicating tube in sequence from bottom to top, and a plurality of straight-through ceramic filters are configured between the first and second flared portions; a waste water diversion pipe is connected to the lower end of the communicating tube; an air inlet is in communication with the communicating tube, being connected to the exhaust outlet of a marine engine; a first exhaust gas flushing device, second exhaust gas flushing device and a third exhaust gas flushing device are configured inside the communicating tube in sequence; the first, second and third exhaust gas flushing devices can spray fluid toward the inside of the communicating tube.

I claim: 
     
         1 . A quick purification device for smoke and exhaust gas discharged from a marine engine, comprising:
 a communicating tube, an axial direction thereof being vertically arranged, a necked portion, first flared portion, second flared portion and exhaust tail tube being formed on a top end of the communicating tube in sequence from bottom to top, the second flared portion being configured in such a way as to be inverted with respect to the first flared portion, a plurality of straight-through ceramic filters being configured between the first and second flared portions, a waste water diversion pipe being connected to a lower end of the communicating tube, and the exhaust tail pipe having an exhaust vent facing upward;   an air inlet pipe, in communication with the communicating tube between the necked portion and waste water diversion pipe;   a first exhaust gas flushing device, configured on an inner circumference of the communicating tube between the necked portion and air inlet, capable of spraying fluid toward an inside of the communicating tube;   a second exhaust gas flushing device, configured on an inner circumference of the communicating tube above the second flared portion, capable of spraying fluid toward an inside of the communicating tube; and   a third exhaust gas flushing device, configured on an inner circumference of the communicating above the second waste gas flushing device, capable of spraying fluid toward an inside of the communicating tube.   
     
     
         2 . The device according to  claim 1 , wherein both ends of the largest diameter of said first and second flared portions respectively face toward the straight-through ceramic filters. 
     
     
         3 . The device according to  claim 1 , wherein said first waste gas flushing device comprises a plurality of atomizing nozzles arranged around said inner circumference of said communication tube, and an orifice of each one thereof faces toward a center of said communicating tube. 
     
     
         4 . The device according to  claim 1 , wherein said second waste gas flushing device comprises a plurality of atomizing nozzles arranged around said inner circumference of said communication tube, and an orifice of each one thereof faces toward a center of said communicating tube. 
     
     
         5 . The device according to  claim 1 , wherein said third waste gas flushing device comprises a plurality of atomizing nozzles arranged around said inner circumference of said communication tube, and an orifice of each one thereof faces toward a center of said communicating tube. 
     
     
         6 . The device according to  claim 1 , wherein a mesh screen is configured on an end of the largest diameter of said first flared portion, and said straight-through ceramic filters are supported thereby.
