DRIER OF SUSPENDED LAYER WITH INERTIAL NOZZLE Russian patent published in 2008 - IPC F26B3/12 

FIELD: procedure of dispersed materials drying.

SUBSTANCE: drier of suspended layer with inertial nozzle consists of drying chamber with gas distributing grid in the form of packet of grids, which are assembled from springs that are installed in single plane, and with inertial nozzle, sprayer, vibration mechanism, which is made in the form of vibrating plates that are installed in drier casing with the possibility of rotation in relation to axes, at that in vibrating plates in staggered order additional plates of different length are rigidly fixed at the angle to vibrating plates that lies in the range of, for instance, 80...40°, at that free tops of additional plates of the right vibrating plate are turned upwards, and of the left one - downwards, at that in the bottom part of casing trapping system is installed, which includes acoustic plant, where acoustic agglomeration of fine particles takes place, cyclone and bag filter with bunker, and sprayer is made as acoustic and contains resonator arranged in the form of toroidal plane, the axis of which is installed coaxially to rod of distributing head, and cavity is connected by at least one calibrated opening with annular gap between vertical opening in end wall of casing and rod of distributing head, which is made in the form of casing with cover in the form of truncated cones, which are joined with their larger bases, at that in the casing there is a collector in the form of cylindrical cavity that is connected with annular channel, which is formed with external cylindrical surface of hollow rod and identical diameter openings that are coaxial with them and arranged in cover and casing of distributing head, with at least three channels for solution outlet that are evenly distributed along the circumference and perpendicular to rod axis, at that cut of openings is installed on conical surface of distributing head cover, the incline angle of which determines the root angle of sprayed solution torch.

EFFECT: increase of drying efficiency.
