Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
230 words
In a cyclone dust-collecting apparatus having a casing of circular cross section and a top wall, a casing inlet, a lower discharge conduit from the casing, an axial gas discharge conduit from the casing extending through the top wall comprising an apertured cylindrical entrance section, an upper cylindrical outlet section of flow area greater than that of the entrance section and an intermediate section communicating between said entrance section and said upper section, the improvement which comprises the aperture to said entrance section being positioned no higher than the horizontal centerline of the casing inlet and no lower than the casing inlet bottom wall, said upper section having a flow area at least equal to the flow area of said casing inlet, the interconnection between said upper section and said intermediate section being positioned above the casing inlet and below the top wall, said intermediate section being of frustoconical configuration and having a flow area intermediate of the flow areas of said upper section and said entrance section, the interconnection between said intermediate section and said entrance section being positioned substantially coincident with the horizontal centerline of said casing inlet, the aperture into said entrance section being of such flow area as to impart to the fluid flowing therethrough a velocity of from about 100 to about 250 feet per second, said gas discharge conduit discharging vertically from said casing.
