Activated carbon method absorption tower, flue gas purification method and desulfurization denitrification system

摘要

The present invention relates to a twin tower type or double row type activated carbon absorption tower, a flue gas purification method, and a desulfurization denitrification system, in the activated carbon absorption tower, each of the left column (1) and the right column (1) is located at the bottom. Activated carbon bed layer part (A), upper activated carbon bed layer part (B), middle switching area (C), first air chamber (G1), second air chamber (G2), third air chamber (G3) located between the two parts ) And a fourth air chamber (G4), the lower activated carbon bed layer portion (A) includes a lower first material chamber (a1), a lower second material chamber (a2), and a lower third material chamber (a3). And, the upper portion of the activated carbon bed layer (B) includes an upper first material chamber (b1), an upper second material chamber (b2), and an upper third material chamber (b3), and a lower first material chamber (a1). Is communicated with each other through the upper first material chamber b1 and the first unloading channel c1 in the row, and the lower second material chamber a2 is in the second row with the upper second material chamber b2. The lower third material chamber (a3) communicates with each other through the unloading channel (c2), and the upper third material chamber (b3) and the third unloading channel (c3) of the row communicate with each other. There is a gap between the multiple unloading channels of. A star wheel type activated carbon discharge roller 106 is mounted below the material discharge port for each material chamber.
