The invention discloses a waste
incineration flue gas spraying deacidification
tower. The top of a
tower barrel is provided with an upper sealing head with an
exhaust pipe, the bottom of the
tower barrel is provided with a lower sealing head with an air inlet
pipe, the side wall of the tower
barrel is provided with a spraying liquid taking opening, and the exterior of the tower barrel is providedwith a spraying pipeline
system; an ascending
pipe communicated with the air inlet
pipe is arranged in the tower barrel, an air distribution cone is arranged at the upper end of the ascending pipe, abaffling cap is arranged at the top of the air distribution cone, and a foam generation cover, a liquid
distribution system, a defoaming
system and a
demister are sequentially arranged above the baffling cap from bottom to top.
Flue gas flows in the tower from bottom to top, a purification liquid flows from top to bottom, when the
flue gas and the purification liquid are in contact with each otherin the foam generation cover, foam is generated, the
flue gas is promoted to be in full contact with the purification liquid, then the dynamic stability of the foam is maintained, and finally the
flue gas is exhausted after being demisted. Compared with a common traditional spraying tower, the spraying deacidification tower provided by the invention is more suitable for waste
incineration flue gas, has better purification effect and reliability, does not need to build a huge purification liquid
treatment system, and has lower construction and operation costs.
