Abstract:
A separation device for the quick separation between particles having a diameter of 1-500 .mu.m and gaseous materials which comprises a vertically oriented inner cylindrical body having a diameter and a closed end which inner cylindrical body forms at the other end an inlet through which a mixture of a catalyst and said gaseous material is introduced, the inlet being in the upper portion of the separation device, and a substantially airtight outer cylindrical body disposed coaxially with said inner cylindrical body in surrounding relation thereto and forming at the upper portion a gas discharging outlet communicating with the outside of said device and at the lower portion a particle-discharging port coaxially disposed with respect to the inlet in the upper portion of the device and communicating with the outside of said device; said inner cylindrical body being provided in the side surface with a plurality of elongated slits extending in the axial direction and spaced equally apart in the circumferential direction and a plurality of curved or flat guide vanes protruding outwardly from the proximity of the longitudinal edges of the slits at a certain angle with respect to the radial direction of the inner cylindrical body and extending vertically in a predetermined length wherein the particle-discharging port has a diameter which is greater than the diameter of the inner cylindrical body.
