Abstract
In an exhaust gas desulfurization apparatus having a cylindrical cage whose axis is substantially vertical and which is revolvable around the axis, and a packing section of an adsorbent material formed in the cage, the inside and outside of the cage being divided by casings and seal means along the periphery into at least four segmental zones respectively for adsorption, desorption, cooling, and adsorbent replacement, whereby the sulfur oxides are removed from the exhaust gas by adsorption by a gas-removing adsorbent and, with the revolution of the cage, the packing zone of the adsorbent is circulatingly shifted in position to the respective zones so that the gas-removing adsorbent is desorbed, cooled, and replaced, the improvement which comprises a packing or particulate separating section of a packing material, smaller in particle size than the gas-removing adsorbent, formed in the cage and outside of the gas-removing adsorbent packing section, so as to pass the exhaust gas through the packing section of the particulate separating packing and thence through the packing section of the gas-removing adsorbent, the gas-removing adsorbent and the particulate separating in the respective packing sections being replaceable independently of each other.
