description	The invention discloses a demisting and dedusting device for a wet chimney of a coal-fired power plant. The demisting and dedusting device comprises, from bottom to top, a gravity hammer, a lower supporting structure, an eddy current distributor, a connecting rod, an eddy current demister, an upper supporting structure and a nozzle, wherein the eddy current distributor is composed of a group of concentric blades and is fixed on the lower supporting structure through bolts, and the lower supporting structure is fixed below the connecting rod through bolts; the eddy current demister is located above the eddy current distributor and is fixed below the lower supporting structure through bolts; the eddy current demister is also composed of a group of concentric blades which are oppositely arranged relative to the blades of the eddy current distributor, so the rotation directions of air flows formed by the blades of the eddy current demister and the eddy current distributor are opposite; and the connecting rod is fixed below the upper supporting structure through bolts, and the upper supporting structure is fixed on the top of the inner wall of the chimney through a detachable fixing device. The demisting and dedusting device has the following beneficial effects: high demisting efficiency, small operation resistance, small flow obstruction effect on flue gas, low energy consumption, convenience in installation and easiness in operation and maintenance.
