High-chlorine silicon slag waste utilization method
The invention discloses a high-chlorine silicon slag waste utilization method which is characterized by comprising the following steps: adding high-chlorine silicon slag into a water tank, and then adding mixed liquid into the water tank, so that the high-chlorine silicon slag is immersed by the mixed liquid. The mixed liquid comprises alkaline water, tetramethyl silicon, trichlorosilane and water, wherein the alkaline water accounts for 10-20% of the mixed liquid, the tetramethyl silicon accounts for 10-20% of the mixed liquid, the trichlorosilane accounts for 10-20% of the mixed liquid, and the water accounts for 40-60% of the mixed liquid; the high-chlorine silicon slag is soaked for 20-60 h. after the silicon slag is treated by adopting the method, solid particles and some toxic substances are filtered in the hydrolysis process of the silicon slag, meanwhile, the emission of chlorine is greatly reduced, and the pollution of the silicon slag to air and environment is reduced; meanwhile, the operation is simple, the cost of the used equipment is relatively low, and the method has advantage on the popularization to manufacturers; in addition, in the purification process, the valuable metal can be collected, waste utilization is achieved, and the economic cost is reduced.
本发明公开了一种高氯硅渣废物利用方法，其特征在于：包括，在水池里加入高氯硅渣，接着将水池里加入混合液体，使得混合液体将高氯硅渣浸过，所述混合液体为碱水、四甲基硅、三氯氢硅、水，其中碱水占混合液体的10～20%，四甲基硅占混合液体的10～20%，三氯氢硅占混合液体的10～20%，水占混合液体的40～60%，将高氯硅渣浸泡20～60h；采用上述方法进行处理后，使得硅渣在水解过程中，将固体颗粒、一些有毒物质进行过滤，同时极大的减少了氯气的排放，减少了硅渣对空气、环境的污染，同时操作简单，所用设备成本较低，便于向厂家进行推广，且在净化过程中，会收集有价值的金属，实现废物利用，降低了经济成本。
