TURBULENT DISTRIBUTING DRYER FOR DISPERSE MATERIALS Russian patent published in 2008 - IPC F26B3/12 

FIELD: heating.

SUBSTANCE: turbulent distributing dryer includes cylindrical drying chamber with nozzles arranged in chord to supply heated gases. Nozzles axes describe tangent to imaginary circle. Dryer also includes sprinkler installed along chamber axis. Besides, dryer is represented with two, sequentially connected cylinders of different diameters. The smallest diameter is 1.0...1.5 of the above imaginary circle diameter. Nozzles are arranged from outlet cross section of small cylinder at distance not exceeding two nozzle diameters. Blades tilted to the gas flow coming out of nozzles are installed in chamber on nozzle levels and in planes parallel to chamber axis and at distance from axis h=aR, where a - chord rate of nozzles, R - chamber radius. Blades are installed so that they can be displaced along chamber axis and rotated in plane parallel to chamber axis. At least, two slotted nozzles mounted on internal wall of large cylinder are provided for dryer. Nozzles in manifolds connected with manifold for heated gases supply by means of pipelines are directed along tangent to large cylinder circle in the point of manifold contact with internal wall of large cylinder.

EFFECT: improvement of economy and drying quality by preventing material sticking to chamber walls.
