An apparatus for treatment of disperse materials comprises a body of rectangular cross-section, a louver-type gas distribution device with rotating blades, a distribution device for supplying solution, a nozzle for supply of a liquefied agent, and a nozzle for removal of oversized material. Inside in the upper part of the body at least three horizontal curved walls are located, which provide a reverse movement of granules to keep the total volume of the bed without its pushing into a cyclone, and which ensure passage of air without a significant increase of hydraulic resistance of the device. |
