Abstract
Abstract A continuous moving layer adsorption device employed in an exhaust gas desulfurization system is made of an adsorption vessel as the main body filled with activated charcoal and a rectifying device included therein, the adsorption vessel main body comprising a side wall provided with a number of louvers and located at the gas-introducing side of the vessel, another side wall having delivery holes located at the gas-exhausting side of the vessel, the distance between the gas-introducing side wall and the gas-exhausting side wall being larger toward the downward portion of the vessel, a hopper-like portion provided adjacently below the two side walls, and an elongated port provided at the bottom of the hopper-like portion for delivering the activated charcoal; and the rectifying device comprising a rectifying body placed in the hopper-like portion and a rectifying place extended downwardly from the rectifying body.
