Title:
AXIAL FLOW-TYPE CYCLONE DUST COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/147373
Kind Code:
A1
Abstract:
The present invention relates to an axial flow-type cyclone dust collection device, which comprises: a turning cylinder portion where dust gas is swirled; a dust gas inlet pipe and a de-dusted gas discharge pipe which are arranged along the axis at the front and rear ends of the turning cylinder portion; and a dust collection port provided in the rear end area of the turning cylinder portion to guide the discharge of the centrifuged dust. In the main body, the inner diameter of the turning cylinder portion is between 1.5 times to 1.6 times the inner diameter of the inlet pipe. A plurality of guide vanes are provided between the dust gas inlet pipe and the turning cylinder portion in the main body so as to provide the dust gas flowing through the inlet pipe with a swirling centrifugal force, and are radially arranged at a changing vane angle of which the lead-in angle in the front end with respect to the axis of the turning cylinder is between 0° and 5° and the discharge angle in the rear end portion is between 75° and 80°. According to the present invention, static pressure loss is small and dust collection efficiency is improved since the mutual geometric relationship between components is optimized.
