US 5,180,257 A · Straightening instrument and cyclone

Abstract

A cyclone comprising a swirl cylinder, an inner tube disposed in the upper section of the swirl cylinder, an inlet duct arranged tangentially to the outer periphery of the swirl cylinder, a drop opening formed in the lower section of the swirl cylinder, and a straightening instrument disposed in a space directly below the inner tube. The straightening instrument includes a conical member coaxial with the inner tube and guide plates arranged along a conical surface at the outer periphery of the conical member. A lower section of each of the guide plates is curved to encounter the turn tangential velocity components of a circumferential spiral stream smoothly into axial velocities alone, and unnecessary vortices which are not required for separation of particles and which cause energy loss are eliminated.

Dependent claims

A straightening instrument comprising:

a conical member having a center axis and a periphery at which a conical surface is formed;
a plurality of reversed triangular shaped guide plates each having at least a lower half section formed as a curved surface and linear in shape when viewed in horizontal cross-section, said guide plates being arranged around said center axis of said conical member at equal angular intervals in directions in which the curved surfaces of said shaped guide plates extend downward to encounter a fluid stream swirling around the outer periphery of said conical member and direct the movement of said stream upward.
