Abstract
A device is disclosed for the quick separation between solid materials and reaction gaseous materials which comprises a vertically oriented inner cylindrical body with a closed end, which cylindrical body forms at the other end an inlet through which a mixture of the catalyst and the gaseous material is introduced 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 port communicating with the outside of the device and at the lower port a particle-discharging port communicating with the outside of the device, the 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. The device is increased in separation efficiency with a short residence time of the gaseous material even when the catalyst particles are contained in the mixture at a higher mix ratio.
