Abstract The present invention relates to an equipment of eliminating SO2 from waste gas ane aims at treating waste gas with waste material and reducing production cost. The special equipment has a pulp mixing tank, which has a cinder powder feeding port and a supernatant liquor feeding port and leads pulp to the absorbant inlet of an absorbing tower. The absorption tower has a fume inlet and a fume outlet, and from the bottom of the absorption tower, reaction product is led to a circulation tank. Partial product in overflowed from the circulation tank to tank of the next stage absorption tower, and the gas after passing through two serially connected showering absorption towers is exhausted. The other partial product is led to settling separation tank, from which supernatant liquor is returned to the pulp mixing tank and the sediment is separated. With low cost, the method of the present invention may be used for environment protection in enterprise.
