Method for efficiently and harmlessly treating aluminum ash
Relates to the technical field of aluminum ash harmless treatment, and discloses a method for efficiently and harmlessly treating aluminum ash, which comprises the following steps: S1, crushing an alkaline absorbent and activated carbon into powder blocks of 8-10mm, mixing the alkaline absorbent and the activated carbon, and grinding in a ball mill to obtain a mixture; s2, putting the mixture subjected to ball milling in the step S5 into a rotary kiln through a stock bin, calcining, carrying out heat treatment in a direct heating manner, and controlling the temperature at 800-1300 DEG C; calcium hydroxide, calcium oxide and calcium carbonate are compounded, so that the fluorine gas treatment effect is better, meanwhile, the treatment effect on toxic and corrosive gases is enhanced, the adsorption effect on the toxic and corrosive gases can be further improved by adding activated carbon, the pores of the activated carbon can be increased through ball milling of the activated carbon, and the adsorption effect on the toxic and corrosive gases is improved. The adsorption effect of the activated carbon can be improved, so that the fluorine gas treatment effect is further improved.
涉及铝灰无害化处理技术领域，本发明公开了一种高效无害化处理铝灰的方法，包括以下步骤：S1、先将碱性吸收剂和活性炭破碎成8～10mm的粉块料，再将碱性吸收剂和活性炭混合放入球磨机进行研磨，即可得到混合料；S2、然后将步骤S5中球磨的混合料经料仓放入回转窑中进行煅烧，采取直接加热的方式热处理，温度控制在800‑1300℃；本发明通过将氢氧化钙、氧化钙和碳酸钙进行复配，使其处理氟气的效果更好，同时增强对毒性与腐蚀性气体的处理作用，并且通过活性炭的添加，能进一步提高对毒性与腐蚀性气体的吸附效果，并且活性炭通过球磨能够提高活性炭的孔隙，则能提高活性炭的吸附效果，从而进一步提高处理氟气的效果。
