<p>PURPOSE:To efficiently treat a waste gas without using ammonia as an additive and with the amt. of calcium oxide or magnesium oxide to be used remarkably reduced by combining a dust collector and a desulfurizer and removing a back corona. CONSTITUTION:Calcium oxide or magnesium oxide is injected on the upstream side of a dust collector impressed with a pulse charge as an additive. The sulfur dioxide contained in a waste gas is oxidized by a pulsed corona discharge into gaseous sulfur dioxide, which is adsorbed by the fine powder of the calcium oxide or magnesium oxide and removed by the dust collector along with the dust.</p> |
