Claims

[Scope of Claim for Utility Model Registration] (1) A cylindrical casing is disposed in the exhaust gas passage of a diesel engine, and a filter member for collecting particulate matter in the cylindrical casing;
In the particulate trap filter regeneration device for a diesel engine, the particulate trap filter regenerating device for a diesel engine includes a burner device disposed upstream of the filter member and for burning and removing particulate matter collected by the filter member. A structure configured to diffuse the combustion gas of the burner device and reduce a temperature gradient from the center to the outer periphery on the front surface of the filter member is disposed between the burner device and the burner device. Diesel engine part pump filter regeneration device. (2) The structure fixes a plurality of guide vanes having an angle with respect to the flow to the cylindrical casing,
The particulate trap filter regeneration device for a diesel engine as claimed in claim 1, characterized in that the guide vane forms a combustion gas inflow space in the center of the cylindrical casing. (3) The structure is a member formed by opening a part of a spherical body having a spherical hollow space, and making the entire opening continuous with the vicinity of the inner peripheral edge of the plate-shaped ring body, and A utility model registration claim characterized in that the spherical body has a combustion gas passage hole and an exhaust gas passage hole, and is fixed to the cylindrical casing so that the intermediate space faces the filter member side. A particulate trap filter regeneration device for a diesel engine according to item 1. (4) The structure has one end of a plurality of guide vanes arranged and fixed in a radial manner on a disc body having a hole in the center,
The other end of the guide vane is fixed to the plate surface of the plate-shaped ring body so that the guide vane forms an air passage that communicates the burner device side space and the filter member side space, and the disc body is fixed to the cylindrical casing so as to be closer to the burner device than the plate-shaped ring body. Device. (5) The diesel engine according to claim 1, wherein the structure is formed by fixing to the cylindrical casing a cylindrical sleeve having a threaded inner surface along the cylindrical casing. Engine particulate trap filter regeneration device.
