FIELD: procedure of dispersed materials drying. ^ SUBSTANCE: drying plant for highly humid materials consists of casing in the form of two truncated cones that are joined with larger bases, gas distributing grid in its bottom part, inertial bodies inside casing, which are arranged as freely suspended threads or tapes, and sprayer of dried material, which is installed at the level of top cone height middle, at that impellers are attached to threads with at least two blades, at that blades may be fixed through one wick, and by chamber height they may be installed in staggered order, and sprayer for material is made in the form of acoustic nozzle and contains resonator that is made in the form of at least one spherical cavity, which is installed in end surface of casing that faces distributing head, at that spherical cavity is connected with calibrated opening to gap between vertical opening in end wall of casing and rod of distributing head, at that in the cross-section that is perpendicular to axis of rod, gap has annular cross-section, and distributing head is made in the form of casing with the cover in the form of truncated cones that are joined by larger bases, at that in the casing collector in the form of cylindrical cavity is installed, which is connected by annular channel that is formed by external cylindrical cavity of hollow rod and single diameter openings that are coaxial with it, which are made accordingly 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. ^ 2 cl, 2 dwg |
