[0002] It is found during use of the existing acid mist absorber that the current acid mist absorber purifies the acid mist by spraying an alkaline solution onto the acid mist, but the contact area between the sprayed water mist and the acid mist is small, so that the water mist cannot fully absorb the impurities and pollutants in the acid mist. Since the impurities and pollution in the acid mist are not fully absorbed by the water, the purification degree of the released gas is not high, which reduces the work efficiency and leads to poor practicality. For this reason, we propose an acid mist absorber for polyaluminium chloride spray drying to solve the problems raised in the above background technology. Utility Model Content
