The invention discloses a wet type electrostatic dust and fog removing device which is of a vertically-arranged pipe type structure. A cathode wire is arranged in the center, and a pipe type anode plate is arranged on the periphery. The upper end and the lower end of the pipe type anode plate are fixed to supporting structures. Smoke can flow reversely from bottom to top and can also flow directly from top to bottom to enter an electric dust remover. When reverse flow arrangement is conducted, a flushing nozzle, a cathode upper supporting structure, an eddy fog remover, an anode upper supporting structure, an anode lower supporting structure, an eddy distributor and a cathode lower supporting structure are sequentially arranged from top to bottom from the top; when direct flow arrangement is conducted, the flushing nozzle, the cathode upper supporting structure, the eddy distributor, the anode upper supporting structure, the anode lower supporting structure, the eddy fog remover and the cathode lower supporting structure are sequentially arranged from top to bottom from the top of the device. The wet type electrostatic dust and fog removing device has the advantage that the dust and fog removing efficiency is improved.
