The invention discloses a novel
flue gas purification
tower which comprises at least two stages of purification chambers, namely, a
drying purification chamber and a main purification chamber from bottom to top. The two stages of purification chambers are of urn-shaped structures with narrow upper parts and narrow lower parts and wide middle parts, the lower end of the main purification chamber extends into the
drying purification chamber and is communicated with the
drying purification chamber, and a guide cylinder is arranged in the center of the communication joint. An arch shoulder is formed at the wider part of the drying purification chamber, a
flue gas inlet connecting
pipe is arranged at the arch shoulder, and absorbent
slurry spraying devices are arranged in inner cavities of themain purification chamber and the drying purification chamber.
Flue gas in the purification
tower moves from bottom to top, and water drops in desulfurization
slurry sprayed by
flue gas in the dryingpurification chamber and the main purification chamber are subjected to a continuous self-circulation process of
evaporation and condensation. In the self-circulation process, complex
heat transfer and
mass transfer effects are generated on the water drops and the
flue gas, and
flue gas purification is achieved. The novel
flue gas purification
tower has the advantages of being simple in structure,high in flue gas purification efficiency, free of waste water, low in operation and maintenance cost and the like.
