ACTIVATED CARBON ABSORPTION COLUMN

摘要

PROBLEM TO BE SOLVED: To improve the removal efficiency of dioxins even if the passing sectional area of flue gas which passes through an activated carbon packed part is enlarged to make the flow velocity of the gas fast, and to set up an activated carbon absorption column in a small site area. SOLUTION: A gas inlet part 6 is installed in one side of a longitudinal activated carbon packed part 1 in which an activated carbon supply port 2 and an activated carbon discharge port 3 are installed on an upper and lower edge respectively so as to pack activated carbon inside. And, a gas outlet part 7 is installed in the other side of the activated carbon packed part 1. A gas inflow pipe 8 is connected with the upper end of the gas inlet part 6, and a gas discharge pipe 9 is connected with the upper end of the gas outlet part 7. A number of holes 11 and 13 are respectively installed in a side wall 1a of the gas inlet part 6 side of the activated carbon packed part 1 and in a side wall 1b of the gas outlet part 7 side of the activated carbon packed part 1 so that combustion gas which moves from the gas inlet part 6 to the gas outlet part 7 can pass through the activated carbon packed part 1 in the horizontal direction. Moreover, a flow-straightening plate 15 in which a number of holes 16 are provided is mounted in the gas inlet part 6 in the vertical direction so that flue gas 10 can horizontally flow from the holes 16 while flowing toward the lower direction.
