Purification tower for treating high-concentration flue gas

The utility model discloses a purification tower for treating high-concentration flue gas. The purification tower comprises a flue gas inlet 12, a flue gas distribution chamber 11, a flushing purification unit 10, a gas collection chamber 6, a rotational flow purification channel 5, a diffusion chamber 4, a spraying layer 3, a centrifugal demister 2, a chimney 1, a stirrer 9, a circulating water outlet 8 and an alkaline liquid chamber 13. The purification tower for treating the high-concentration flue gas can effectively purify the high-concentration flue gas by adopting working processes such as flushing purification, rotational flow purification, spraying purification and centrifugal demisting, so that a discharging standard can be achieved and the running is stead and normal.
