DEVICE FOR SEPARATION OF GAS AND SOLID PARTICLES SUSPENDED IN IT Russian patent published in 1998 - IPC

FIELD: oil refining; devices for separation of vaporous products of cranking or flue gases and catalyst particles suspended in them at outlet of transportation lines of reactor regenerator unit of catalytic cracking plant. SUBSTANCE: proposed device includes intake chamber connected with branch pipe at end of pneumatic transportation line whose outlet section is bent through 45-180 deg at radius of 1.0-7.0 of minimum transversal sizes of branch pipe and with solid particles receiving chamber; device includes also gas discharge chamber connected with final gas cleaning units and vortex chamber; number of intake, gas discharge and vortex chambers and branch pipes ranges form 1 to 8; longitudinal surface of vortex chamber is bent through 60-360 deg at radius of 0.8-6.0 of minimum transversal sizes of branch pipe; it is connected with gas discharge chamber and solid particles receiving chamber; gas discharge chamber is mounted inside vortex chamber in such way that axis of longitudinal surface of vortex chamber is parallel to longitudinal surface of gas discharge chamber and flow section at vortex chamber inlet is equal to 40-95 percent of outlet section of branch pipe at end of pneumatic transportation line. EFFECT: enhanced efficiency of separation of gas and suspended particles at retained separation time. 5 dwg, 1 tbl
