Henan Shangyu New Energy Co., Ltd. The company independently researched and developed the recycling technology of trichlorosilane-waste silicon powder that has been authorized by the national invention patent. For the first time, this technology uses high-efficiency multi-stage cyclone separation technology to recover unreacted spent silica fume and reincorporate it into the reaction system. With the application of the technology, the silicon powder unit consumption was reduced from 0.26 to 0.28 tons to 0.24 tons, and the annual cost savings can be more than 4 million yuan. The problem of producing waste silicon powder in the production of trichlorosilane has been plagued by companies for a long time. Currently, most domestic companies do not install waste silica recovery equipment, and they are generally discharged directly to the washing tower. A few manufacturers discharge waste silica into large-capacity ash storage tanks, which are then manually discharged. These traditional processes are both wasteful and polluting the environment.
