一种粉煤灰酸溶渣沉降槽分离洗涤方法和装置
摘要：
本发明涉及一种粉煤灰酸溶渣沉降槽分离洗涤方法和装置，其中所述的方法包括部分溢流循环的分离沉降步骤以及两级或两级以上的循环洗涤沉降步骤。所述装置包括分离沉降机构和两级或两级以上的循环洗涤沉降机构。本发明可以显著提高酸溶渣的分离效果；本发明也可以很好的减少酸溶渣附液的含酸率，从而满足排放要求；并且沉降底流固含较高。
摘要（英）：

The invention relates to a fly ash acid solution residue settling tank separation and washing method and a device, wherein the method comprises the separation settling step of partial overflow cycle and the cyclic washing settling step with two or more steps. The device comprises a separation settling mechanism and a cyclic washing settling mechanism with two or more stages. The invention can significantly improves the separation effect of acid solution residue, well reduce the acid content rate of the attached liquid of the acid solution residue so as to meet the discharge requirement and the settling underflow solid content is higher.
