Recovery system for silicon powder in solid waste in chlorosilane production

A silicon powder recovery system in chlorosilane production solid waste comprises a silicon powder bin, a solid waste conveying pipeline is arranged at the top of the silicon powder bin, a spiral conveyor is arranged at the bottom of the silicon powder bin and used for conveying solid waste to a silicon powder washing tower, a silicon powder washing pool is arranged at the bottom of the silicon powder washing tower, and a waste water circulating pipeline is arranged at the bottom of the silicon powder washing pool. The wastewater circulating pipeline is connected with a spraying device in the silicon powder washing tower, and a wastewater circulating pump is arranged on the wastewater circulating pipeline; an emptying pipeline is arranged at the top of the silicon powder washing tower. According to the utility model, the equipment and the process are optimized, so that the amount of waste water is reduced, and the silicon powder is recycled. 一种氯硅烷生产固废中的硅粉回收系统，包括硅粉仓，硅粉仓顶部设有固废输送管道，硅粉仓底部设有螺旋输送机，螺旋输送机用于向硅粉水洗塔输送固废
