Abstract
An apparatus for removing acid substances from hot flue gas includes a scrubbing device and a washing screen device. The scrubbing device includes reactors, each having two rows of outlet louvers, two rows of inlet louvers provided on two sides of the outlet louvers, two reagent beds, each being confined by one row of the outlet louvers and one row of the inlet louvers, and each containing a granular reagent, and an outlet channel confined by the rows of the outlet louvers to permit the gas to exit from the reagent beds. The washing screen device is mounted below each of the reactors and is operable so as to vibrate and screen the granular reagent falling thereon so that the granular reagent is retained on the washing screen device while wastes are allowed to pass through the washing screen device.
