Integration SOx/NOx control reaction tower

The utility model relates to an integration SOx/NOx control reaction tower, including the tower body and set up from bottom to top spray layer, natural oxidizer in inside desulfurizing slurry pond, the desulfurization of tower body, keep apart the plywood, the denitration sprays layer and the defroster. Be provided with original flue gas entry, air inlet, denitration agent export and clean exhanst gas outlet on the tower body. Integration SOx/NOx control reaction tower take desulfurization section and the setting of denitration section subregion, but simultaneous processing SO2 and NOx. The original flue gas that contains SO2 and NOx gets into the absorption tower from the original flue gas entry, and spray the reverse contact of atomizing desulfurizing slurry of spraying on the layer and the desorption falls SO2 with the desulfurization, and the desulfurizing slurry pond that the desulfurizing slurry that has absorbed SO2 got into the reaction tower bottom recycles. Flue gas after the desulfurization gets into the natural oxidizer at reaction tower middle part, and with air contact natural oxidation, then the denitration that gets into the reaction tower upper strata sprays the layer, sprays the reverse contact of atomizing denitration agent of spraying on the layer with the denitration and accomplishes a denitration, having absorbed NOx's denitration agent and having followed the denitration agent export discharge reaction tower that sets up keeping apart the plywood top, the clean flue gas behind the SOx/NOx control is followed the reaction tower top and is discharged behind the defroster defogging. The utility model discloses accomplish SOx/NOx control simultaneously in a single column equipment, does not need the catalyst, overcome in the existing market flue gas SOx/NOx control limitation of desorption in reactor alone respectively, greatly reduced investment cost, have that technology is succinct, the desorption is efficient, area is little, can set up in a flexible way according to the on -the -spot condition, running cost low grade characteristics.
