AERODYNAMIC DUST COLLECTING APPARATUS Russian patent published in 1998 - IPC

FIELD: devices for cleaning gas from dust. SUBSTANCE: aerodynamic dust collecting apparatus includes aerodynamic dust collecting modules made in form of tapering rings or plates, dust discharge branch pipes and bin. Aerodynamic dust collecting modules are connected to gas-dynamic passage through gas duct section connecting members. They are provided with hatches which close hermetically and are located along lateral surface of thin walled casing. Modules are mounted on supports either horizontally or vertically relative to gravity field at side or end inlet of dust discharge branch pipes to dust settling bin; bin is provided with hermetically closing gate valve fitted in its lower portion; this gate valve is automatic or semiautomatic. EFFECT: enhanced efficiency. 7 cl, 27 dwg
