TLDR
In this paper, a spray tower is used for cleaning waste flue gas, where a reactant solution is sprayed into a waste gas, and the water contained in the droplets is vaporized and the reaction products are dried into solid particles by the sensible heat of said flue gases.Abstract:
A waste flue gas cleaning method and an apparatus for practicing said method, in which a reactant solution is sprayed into a waste flue gas introduced into a spray tower, whereby a toxic component in the flue gas is caused to be absorbed in and react with the droplets of the sprayed reactant solution, and the water contained in the droplets is vaporized and the reaction products are dried into solid particles by the sensible heat of said flue gas. A series of the above operation is accomplished within the spray tower while maintaining the outlet gas temperature always above the dew point of the flue gas, and the solid particles of the reaction products are removed from the flue gas by an after dust collector.read more
