FIELD: technological processes, drying. ^ SUBSTANCE: invention is related to equipment of drying disperse materials in boiling layer and may be used in aniline-painting, food, pharmaceutical, microbiological, chemical and other industries. In spraying drier of boiling layer with inertial nozzle, which contains drying chamber with gas distributing grid, vibration plates of vibration mechanism, which are installed in the drier casing with the possibility of rotation in relation to axes, inertial nozzle, sprayer, on vibration plates in staggered rows additional plates are rigidly installed of different length at the angle to vibration plates, which are located in the range, for instance, of 80...40°, at that free tops of additional plates on the right vibration plate are inverted upwards, and on the left one - downwards, at that in the bottom part of casing the catching system is installed, which includes acoustic device, where acoustic agglomeration of small particles takes place, cyclone and sleeve filter with hopper, and sprayer is made as acoustic and contains resonator, which is made in the form of toroidal cavity or at least one spherical cavity, which is located in the end wall of casing, which is inverted to the distributing head, at that the spherical cavity is connected by calibrated opening with gap between vertical opening in the end wall of casing and rod of distributing head, at that in the cross section that is perpendicular to the rod axis, the gap has a circular section, and inertial nozzle is made in the form of hollow balls, in the spherical surface of which there is a spiral groove or the nozzle is made in the form of spiral line, which is created on the spherical surface, and has in its section, which is perpendicular to spiral line, profile of circle type, or polygon, or Berl saddle or seat Itallox; or the nozzle is made in the form of cylindrical rings, on the side surface of which there is a spiral groove; or the nozzle is made in the form of spiral line that is created on the cylindrical surface, and has in its section, which is perpendicular to spiral line, profile of circle type, or polygon, or Berl saddle or seat Itallox; or the nozzle is made in the form of toroidal rings, or the nozzle is made in the form of toroidal rings that have , of circle type, or polygon, or Berl saddle or seat Itallox. ^ EFFECT: increases capacity of disperse materials drying in boiling layer. ^ 6 cl, 5 dwg |
