Doublestage subregion sprays desulfurizing tower

The utility model discloses a doublestage subregion sprays desulfurizing tower, including the tower body, the higher level is circulated and is equipped with the gas -liquid redistributor between desulfurization district and the circulation desulfurization district of subordinate, the gas -liquid redistributor includes inclined floor, air duct, gas -liquid division board and gas distribution ware, the hang plate is opened with minimum contact department of tower body has the flow liquid hole, and the air duct is worn to establish on inclined floor, and the gas -liquid division board is fixed in the top of air duct, the top at the gas -liquid division board is fixed to the gas distribution ware. The utility model has the advantages that: having reduced to spray the distance of layer and gas -liquid redistributor, having reduced the height and the operating power consumption of desulfurizing tower, the gas -liquid redistributor makes the washing thick liquid in circulation desulfurization district of the superior and the subordinate be dutiful to separate, do not produce the weeping, steerable operation under the relatively independent different ph values, and the higher level who makes high ph value is circulated the desulfurization and is distinguished the higher desulfurization efficiency of acquisition, and subordinate's circulation desulfurization of hanging down the ph value is distinguished and has been improved the utilization ratio of absorbent and the quality of accessory substance.
