ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to structures for processing wet exhaust from diesel engines and more particularly to devices for quieting the exhaust and for removing the water and other impurities from the wet exhaust gases by entrapping them in a water bath so that cleaner gases are discharged into the atmosphere while the device removes the sheen, excess water, and impurities from the water bath so that fairly clean water is discharged from the device.
2. Description of Prior Art
U.S. Pat. No. 5,746,630 discloses a housing having a tangential inlet for inducting exhaust flow and a first outlet for dried exhaust gas and a second outlet near the bottom for draining water from the housing. U.S. Pat. Nos. 5,196,655; 5,554,058; and other patents also shows a muffler device for silencing exhaust and removing impurities. However, none of these devices does it in the manner of or as well as my invention.
SUMMARY OF THE INVENTION
The present invention includes a container for receiving diesel engine wet exhaust through an inlet tube having a slot therein intermediate the ends thereof. The lower portion of the container has a false bottom therein which has an access opening therethrough in fluid communication with the portion of container above the false bottom. The wet exhaust gases enter the container above the false bottom and a pool of water overlying the false bottom and extending into the false bottom entraps water, oil and particles from the incoming exhaust gases in the portion thereof above the false bottom while an exhaust outlet above the water level carries “cleaned” exhaust gases form the unit. Oil and particles, such as carbon from the exhaust are entrapped as a layer of sheen on top of the water pool and a pick up tube confluent with the surface of the pool removes these impurities for further processing in another device not a part of this invention. A water over-flow tube, which extends from below the false bottom to a level above the lower end of the pick up tube, drains excess “cleaned” water from the pool at the bottom thereof and discharges the water from the device to thereby control the water level of the pool and discharge “clean” water. In a first embodiment angled baffle plates in the water pool above the false bottom are impinged upon by the circulating water so that oil and other particle matters are forced to the surface of the water as a layer of sheen which is picked up by the pick-up tube. A second embodiment utilizes a weir and dam arrangement to force the sheen to the surface so that the pick up tube may withdraw the sheen from the surface.
