Document Type and Number:
WIPO Patent Application WO/2019/003379
Kind Code:
A1
Abstract:
A dust collection device (1) is provided with: a plurality of dust collection bodies (2) that are charged by friction and arranged with spaces therebetween such that air ducts (20) for passage of air are formed; and one or more friction bodies (3) for applying friction to and charging the dust collection bodies. At least one of the dust collection bodies facing each other across an air duct has one or more protruding parts (21) protruding into the air duct. With this dust collection device, it is possible to improve particle collection efficiency in a friction charged dust collection device by forming a nonuniform electric field surrounding a charging body so as to induce gradient force.
