Abstract
The utility model discloses a water film distributing plate boiling type desulphurization duster which comprises granite and a whole fast-assembly type steel cylinder, wherein a plurality of layers of distributing plates are installed in the cylinder, and the core technology lies in the difference of circular holes on the distributing plates, circular holes on the distributing plates on the lower layers are larger, and the circular holes on the distributing plates on the adjacent upper layers are smaller, and the circular holes on the distributing plates are in a circular truncated cone shape, the bottom area of the circular hole is bigger than the top area thereof, therefore, the circular holes on the distributing plates on the upper layers are smaller, and the circular holes on the distributing plates on the lower layers are bigger. A dust inlet in the utility model must be arranged on the lowest portion, thus the large circular holes on the lower layers of the distributing plates allow a great amount of smoke to pass through, and simultaneously satisfy the requirement of passing through falling dust water. As the higher layers of the distributing plates, the thinner smoke filtered, the fewer dust water born, and the circular holes of the distributing plates are smaller. Water droplets on the distributing plates can form the boiling type owing to the effect of a draught fan and the circular truncated cone shaped circular holes, and the fine filter effect can be realized when the content of dust in water droplets reaches a certain level, and water droplets fall down from the distributing plates as a result of gravity.
