The invention discloses a wet dust remover with a wheel-shaped rotating brush. The wet dust remover is arranged on a bracket. The upper part of the left side of a circular box-shaped enclosure is provided with a rotating brush motor, the center of the enclosure is provided with a main motor, the lower part of the enclosure is provided with a water level controlling device, a cavity for accommodating water is formed between the right side of the enclosure and a front cover, the front cover is provided with an air suction port, the front end of the enclosure is provided with an exhaust port, and the lower end of the enclosure is provided with a blow-down valve. Both the water level controlling device and a blow-down pipe are communicated with the water. The center of the left side of the enclosure is provided with a rotating brush disc shaft. The rotating brush disc shaft is connected with a rotating brush disc through a bearing. The rotating brush motor shaft is connected with a rotating brush driving wheel. The main motor shaft is connected with a centrifugal impeller. The circumference of the rotating brush disc is provided with the wheel-shaped rotating brush. The rotating brushdriving wheel is connected with a rotating brush disc driving belt. The rotating brush disc can rotate on the main motor shaft. The wheel-shaped rotating brush consists of a plurality of equal-lengthcolumnar hairbrushes distributed on the rotating brush disc annularly and uniformly. Hairbrush fibers are mutually crossed and overlaid. The hairbrush fibers are periodically and sequentially driven into water and wetted. The dust remover is integrated with a fan, and has simple and reasonable structure, unique bionic design and good dust removal effect.
