摘 要: 以國內(nèi)某冶煉廠銅電解槽為原型，基于計算流體力學，利用Fluent軟件對銅電解槽內(nèi)流場進行數(shù)值模擬，并對槽內(nèi)不同特征截面上電解液流動狀態(tài)進行分析。結(jié)果表明：模擬計算得到的槽面電解液流動狀況與現(xiàn)場觀測結(jié)果基本吻合，從而驗證模擬結(jié)果的有效性；采用該“下進上出”電解液循環(huán)方式對槽內(nèi)特征區(qū)域電解液的有效流量進行計算，發(fā)現(xiàn)電解液有效利用率僅15.41%左右。針對該問題分析成因后提出了具體建議和措施，為進一步優(yōu)化電解槽結(jié)構(gòu)、改進操作工藝和擴大產(chǎn)能提供理論依據(jù)。

Abstract:With the copper electrolytic cell of domestic copper smelter as the prototype based on computational fluid dynamics, the flow fields in the copper electrolytic cell were simulated with Fluent software，and the flow condition of electrolyte on different characteristics cross-section inner cell were analyzed. The results show that the electrolyte flow conditions from simulation basically agrees well with the local observation results, then, the effectiveness of simulation results is validated. The electrolyte effective flux in characteristic region using the “Bottom inlet to top outlet” circulation way of electrolyte were calculated, and the effective utilization of the electrolyte is only about 15.41%. After analyzing of the causes for the problem, the specific suggestions and measures were proposed，and the theoretical basis to optimize the cell structure, improve operation process and expand capacity was put forward．
