Abstract

The utility model discloses waste gas treatment equipment which comprises an efficient absorption tower, a circulating system, an oxidation absorption system, a medicament supply system and a controller, the efficient absorption tower comprises a tower body, and a flue gas inlet, a packing layer, a new medicament liquid spraying layer, a circulating spraying layer, a demister and a purified air outlet are sequentially arranged in the tower body from bottom to top. The new medicament liquid spraying layer is communicated with a medicament supply system, the flue gas inlet is communicated with a flue gas inlet pipeline, an oxidation absorption system is communicated in the flue gas inlet pipeline, the circulating system is communicated with the tower bottom and the circulating spraying layer, and the controller is communicated with and controls the circulating system, the oxidation absorption system and the medicament supply system. According to the utility model, a combined structure of front oxidation cooperating with absorption of the efficient absorption tower is adopted, the absorption tower adopts a combined spraying mode of circulating liquid and new medicament liquid, the performance is higher, instruments such as an inlet pollutant concentration detection instrument and a PH meter are adopted for controlling and cooperating with outlet pollutant concentration feedback correction control, various control such as single control, combined control and the like is realized, and the device is more accurate.
