Activated carbon method absorption tower, flue gas purification method and desulfurization and 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 and denitrification system, in the activated carbon absorption tower, each of the left tower (1) and the right tower (1) is a lower Activated carbon bed layer section (A), upper activated carbon bed layer section (B), central transition region (C) located between these two sections, first air chamber (G1), second air chamber (G2), third air chamber (G3) ) and a fourth air chamber G4, and 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 activated carbon bed layer portion (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 the upper first material chamber b1 and the first unloading channel c1 in one row, and the lower second material chamber a2 is connected to the upper second material chamber b2 and the second in one row. It communicates with each other through the unloading channel c2, and the lower third material chamber a3 communicates with the upper third material chamber b3 and the third unloading channel c3 of one row, each row A gap exists between the multiple unloading channels of A star wheel type activated carbon discharge roller 106 is mounted under the material discharge port of each material chamber.
