Rotational flow plate washing tower for removing dust pollutants and treatment process of washing tower

The invention provides a rotational flow plate washing tower for removing dust pollutants and a treatment process of the washing tower. The rotational flow plate washing tower comprises a treatment tower and a dehydration tower, the upper portion of the treatment tower communicates with the dehydration tower, a tower plate is arranged in the treatment tower, the tower plate comprises a cover cylinder and plate sheets, the plate sheets are obliquely arranged on the inner side of the cover cylinder, the groups of plate sheets are equidistantly arranged around the circle center of the cover cylinder, a liquid collecting tank is formed between the cover cylinder and the tower wall in the inner side of the treatment tower, a downcomer hole is arranged at the bottom of the liquid collecting tank, and a downcomer pipe is connected below the downcomer hole; through the guiding effect of the tower plate, when waste gas obliquely penetrates through gaps between the plates along the inclination angle, a rotational flow
