FIELD: heating. ^ SUBSTANCE: drying plant for thermolabile materials mainly for calcium hypochlorite contains chamber, injector for calcium hypochlorite mother solution, pipeline for inert gaseous coolant supply, dried-out material discharge spout connected with pipeline where dried-out material is transported pneumatically, connection pipe for extra coolant supply to pipeline. The other end of pipeline is connected with dust cleaning system. Dust cleaning system is notable for injector, which sprays calcium hypochlorite solution, is acoustic and contains resonator, which is represented with, at least, one spherical hollow located in end wall of housing directed to distributing head. Besides, spherical hollow is connected with gap between vertical opening in end wall and distributing head rod by means of calibrated opening. In addition, gap is of annular cross section in the section perpendicular to rod axis. Distributing head is in the shape of housing with cover represented with truncated cones interconnected by large basis. Besides, manifold in the form of cylindrical hollow is located inside the housing. Manifold is connected with annular channel formed by external cylindrical surface of hollow rod and coaxial openings of similar diameter provided in distributing head cover and housing. Distributing head is provided with, at least, three channels for solution discharge, which are evenly distributed around and perpendicular to rod axis. In addition, opening shearing is on the tapered surface of distributing head cover. ^ EFFECT: improvement of drying efficiency. ^ 2 cl, 2 dwg |
