六、硅渣分离设备在生产中的作用 (一)硅渣沉降槽硅渣沉降槽是将脱硅后含有硅渣的溶液,进行初步的液固分离,使90％以上的硅渣沉降下来。为了提高叶滤机的产能,应尽量减小沉降溢流中的浮游物含量。除了分离脱硅后的浆液外,还起二次脱硅反应器的作用。增加CaO添加量,可以使脱硅后溶液 Six, silicon residue separation equipment in the production of role (a) Silica sedimentation tank Silica sedimentation tank is desiliconized silicon slag solution, the initial liquid-solid separation, so that more than 90% of the sediment deposition of silicon. In order to increase the productivity of the leaf filter, the float content in the sedimentation overflow should be minimized. In addition to separating the desiliated slurry, it also functions as a secondary desiliconization reactor. Increase the amount of CaO, can make the desiliconized solution
