DEDUSTING DEVICE

PROBLEM TO BE SOLVED: To solve problems that the centrifugal force is not enough as a force for shaking off dust of a filter, so that unremoved dust remains in the filter, resulting in frequent occurrence of clogging, and air flow path is complicated, resulting in high pressure loss as a dedusting device, in a conventional dedusting device using a filter clogging removing means by centrifugal force. SOLUTION: As shown in Fig.3, the filter 7 is provided with a centrifugal air blowing blade 8 and the filter 7 is cleaned with a straight brush 23 while generating air flow from the inside toward the outside, so as to increase the force for shaking off dust, thereby making frequency of clogging low. A roughly conical configuration of the filter 7 results in reduction in the pressure loss in the air flow path. The dedusting device 1 has an inspection door 5 on the lower face of a casing 3 connected to the intermediate part of the duct 2, so that maintenance work from the inside of a chamber is made easy.
