Abstract:
An apparatus for the treatment of a desulfurization absorbing fluid after gas-liquid contact with combustion exhaust gas containing fine particles of unburned carbon and other materials, which comprises a treating tank for storing the absorbing fluid containing the fine particles, the treating tank having an absorbing fluid feed port for feeding the absorbing fluid into the treating tank, and a gas feed port for feeding a gas into the absorbing fluid stored in the treating tank and thereby producing gas bubbles to create a foam phase consisting of the gas bubbles in the treating tank; a foam breaking tank adjoining the treating tank; a foam inlet pipe for connecting the treating tank with the foam breaking tank in fluid communication relationship; and foam breaker means disposed in the foam breaking tank for breaking the foam phase having passed through the foam inlet pipe to obtain a liquid containing the fine particles.
