Cyclone

Claim 1

A cyclone device comprising: a cylindrical tubular body having a vertical central axis and a ceiling for defining a space, said sealing having a circular opening with a center at an eccentric location with respect to said central axis; a tapered body portion connected to a lower edge of said cylindical tubular body, tapering inwardly and downwardly and having a lower central solid particle outlet opening; a fluid inlet connected tangentially to said cylindrical tubular body for supplying fluid with particles to be separated, to said space in a tangential direction around said central axis, said fluid inlet connected to said body at a location to cause the fluid to rotate in said body around said central axis in a rotation direction; a cylindrical fluid discharge pipe connected to said ceiling around said circular opening therein, said pipe opening into said space and terminating at said ceiling and before said pipe extends into space, no part of said fluid discharge pipe extending into said space; and a vertical guide plate having a semi-circular horizontal cross-sectional shape, extending downwardly from said ceiling only part of the vertical distance of said cylindrical tubular body, said semi-circular guide plate having opposite vertical edges and extending from a part of said opening in said ceiling downwardly into said cyindrical tubular body, said semi-circular guide plate plate being the only structure extending downwardly into said space and being asymmetrically positioned with respect to said semi-circular guide plate being the only structure extending downwardly into said space and being asymmetrically positioned with respect to said central axis, a radially inner one of said vertical edges being in the vicinity of said central axis and a radially outer one of said edges being near but spaced away from an inner surface of said cylindrical tubular body, said semi-circular guide plate being disposed approximately three-quarters of the way round said rotation direction and being convex in a direction facing said location where said fluid inlet is connected to said body, said semi-circular guide plate being concave in a direction facing oncoming fluid moving in the rotation direction; whereby fluid entering through said fluid inlet and moving around said space defined by said cylindrical tubular body engages against said semi-circular guide plate which reduces an amount of rotation of fluid in said tubular body and advances a separation of particles from the fluid, the fluid moving upwardly through said discharge pipe and the particles moving downwardly through said solid particle opening.
