The invention discloses a new cross-convective
flue gas purification absorption
tower. The new fault-convective
flue gas purification absorption
tower from top to bottom comprises a feeding hopper, a distributing device, an active
coke bed layer and a discharging hopper communicated in sequence, wherein a middle
flue gas collecting chamber is arranged in the active
coke bed layer; the two-layer discharging hopper is arranged at the lower part of the active
coke bed layer; the external part of the active coke bed layer is divided into an upper pure
flue gas collecting chamber and a lower raw
flue gas distributing chamber by a two-layer annular separating plate; an outlet flue is formed in the upper part of the pure
flue gas collecting chamber; a raw flue gas inlet flue communicated with the raw flue gas distributing chamber is arranged at the lower part of the raw flue gas distributing chamber; and the active coke bed layer, the middle flue gas collecting chamber, the raw flue gas distributing chamber and the pure flue gas collecting chamber and the cross section of the overall
tower body are circular. By adopting the absorption tower disclosed by the invention, the removal efficiency of the
pollutant in the flue gas is high; the removal efficiency of SO2 is greater than 96%; the removal efficiencies of SO3, HCl and HF are greater than 98%; the removal efficiency of heavy
metal Hg is greater than 90%; and the dust collection efficiency is greater than 80%; and meanwhile, the absorption tower disclosed by the invention also has the advantages of being convenient and uniform in feeding, smooth in blanking, high in
utilization rate of the active coke and easy to enlarge.
