Abstract
A semi-dry type electrostatic cyclone sampler includes a cyclone body, an insulate element, a discharge electrode, an air tube, an air introducing means, a discharging means and a flushing means. The insulate element is disposed at a top of the cyclone body and co-defines a cyclone chamber with the cyclone body. The discharging electrode is disposed on the insulate element. The air tube is disposed at a bottom of the cyclone body. The air introducing means is for introducing a particulate-containing air stream into the cyclone chamber. The discharging means is for charging the particulates so that the particulates can attach to an inside of the cyclone body. The flushing means is for flushing the inside of the cyclone body and collecting part of the particulates. When the discharging means activates, the air introducing means activates simultaneously. When the flushing means activates, the discharging means is deactivated.
