Description of the Related Art Conventionally, a so-called dry filtration system has been widely used as a dust collector, in which dust-containing air is separated and collected through a filter medium such as filter paper, filter cloth, glass fiber or the like. This filter type dust collecting method has the advantages of high dust collecting performance, a simple structure, and easy maintenance such as filter replacement. In addition, there is a so-called centrifugal dust collector that removes dust-containing air by a cyclone flow.
This is a structure in which dust-containing air is blown in a tangential direction from the upper portion of a cylindrical portion, and is swirled along an inner wall surface, and is exhausted from a discharge pipe of the cylindrical portion by an ascending airflow generated in a central portion. When swirling inside the cylinder, the dust in the dust-containing air collides with the wall of the cylinder with a large centrifugal force, sediments, and is collected in the lower dust box.

Further, the filter method has fundamental disadvantages such as secondary environmental pollution in which fine dust is contained in exhaust gas, propagation of mites and bacteria, and generation of offensive odor. Also,
The centrifugal dust collector has a drawback that fine dust of about 1 μm cannot be removed as compared with the filter system, and there is also a problem that when dust accumulates on the hopper, the dust is blown up and the efficiency is significantly reduced.
