APPARATUS FOR ASEPTICIZING AIR Russian patent published in 1997 - IPC

FIELD: medical engineering, equipment for asepticizing air in microbiological and food industries. SUBSTANCE: apparatus comprises metallic cylindrical casing with piezoelectric generator, negative output of which is rigidly coupled to shaft of eight-blade electrode-impeller, while its positive output is connected to electrode in the form of electroconductive disc provided with conically shaped hollow elements and channels being arranged in chess-board pattern. Inventive novelty of proposed apparatus resides in fact that its piezogenerator is constituted by "n" unitary blocks, each of which represents lever-less tandem structure consisting of opposite arranged and opposite-energized piezoelectric elements made of segnetopiezoelectric ceramics. electroconductive disc and impeller are arranged so that they can be moved apart or drawn closer, impeller blades are made sharpened. Apparatus is energy-saving, as it does not require energy supply from outside, as distinct from similar prior-art devices. Apparatus can be turned out in alternative embodiment in which it consists of self-contained individual modules. With this embodiment, there is no need to carefully isolate air duct portion in which apparatus is placed. EFFECT: simple and easily adaptable to mass-scale production. 2 cl, 6 dwg
