Marine water drop muffler

摘要

A water drop muffler for use in a marine exhaust system to silence exhaust noise while separating entrained water from exhaust gas using hydro-dynamic centrifugal separation principles enhanced by turbulent flow. A muffler housing defines an internal volume bounded by a generally vertically disposed cylindrical inner surface formed about a longitudinal axis. An exhaust inlet receives a mixture of exhaust gas and entrained cooling water. A flow channel transitions the flow for discharge through an opening thereby creating vortex flow within the housing to maximize the generation of centrifugal forces. Water is drawn toward the cylindrical inner surface and allowed drain from the housing.

主权项

1. A marine exhaust component comprising:
a housing defining an internal volume bounded by a generally vertically disposed cylindrical inner surface, a top, and a bottom; an exhaust inlet connected to said housing; said exhaust inlet in fluid communication with a flow channel terminating in a vertically elongate terminal opening disposed substantially adjacent to said cylindrical inner surface; a baffle projecting upward from said housing bottom and partitioning said internal volume generally into an upper chamber disposed above said baffle, and a lower chamber disposed below said baffle, said baffle including at least one opening therein to allow water to flow into said lower chamber; a water outlet pipe having an inlet in fluid communication with said lower chamber, and an outlet; an exhaust gas outlet pipe in fluid communication with said upper chamber and projecting axially from the top of said housing; whereby water in said lower chamber flows out of the housing via said water outlet pipe, and exhaust in said upper chamber flows out of said housing via said exhaust outlet pipe.
