- the swirl flow generated in the guide vane 20 is biased at the position of a specific azimuth angle, so that the velocity distribution is uneven and the swirling of the impregnated gas This will deteriorate the dust collection efficiency.
- the impregnated gas introduced into the turbulent or vortex state is changed to laminar flow when passing through the inflow pipe 12 having a sufficient straight length, so that the velocity and density are uniform. This becomes large and the dust collection efficiency worsens.
