WHIRLING HEAT EXCHANGING APPARATUS Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has casing 1 with end upper wall 5 and end lower wall 7, provided with ring gaps 12 and 13, as well as mixing chamber 3, cylindrical whirling device 8 and conical whirling device 9, provided with tangential gaps, as well as central gas releasing pipe branch 10, loading and unloading bins. Distributing cone 4 is installed on upper end wall 5 symmetrically to apparatus axis. Conical whirling device 9 is made in the form of a set of conical whirling devices, installed coaxially one over another. Their internal surfaces are made in the form of parabola with the vertex, shifted towards expanded part of the whirling device. The central gas releasing pipe branch is made in the form of a set of cylindrical shells locater over axis of the whirling devices. Number of shells equals number of conical whirling devices, and they are installed coaxially having a gap between each other enabling their vertical displacement. Length of any shell is less than length of any previous one by a value equal to the height of working volume of previous whirling device. Additional walls 6 are located under any conical whirling device. EFFECT: highly effective heat exchange. 1 dwg
