Title: Black smoke removing muffler
Inventor: INOMATA TOMOHISA
IPC: F01N1/12
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent internally accumulated black smoke fine particles from being discharged to the outside even when the flow rate of exhaust gas is changed. SOLUTION: An exhaust gas flowing into an equipment body 12 through an exhaust pipe 11 is guided circumferentially by a guide member 16 to form a turning flow. Black smoke fine particles centrifugally separated by the turning flow is separated to the peripheral side, and pure exhaust gas on the center side is discharged to the outside through an exhaust pipe 13. An annular filter member 20 is provided on the inside surface of the equipment body 12 between a second bottom plate 15 and a bulkhead 18.  Although the exhaust gas is blown from a second bottom plate 15 side to a first bottom plate 14 side through the opening of the bulkhead 18 when the flow rate of the exhaust gas is suddenly reduced, a possibility of the black smoke fine particles being moved to the first bottom plate 14 side and discharged to the outside is minimized since the black smoke fine particles are stably held by the tissue of the filter member 20.
