水冷滚筒作为电解铅阴极板制备的核心部件之一,其内部冷却水的流场分布直接决定电解铅阴极板的结板厚度和均匀度。为准确掌握滚筒内流场分布状况,运用计算流体力学软件Fluent的多坐标参考系对水冷滚筒内部的流场进行三维模拟,直观地显示水冷滚筒内部的流场特性和流动状态。通过对不同的出水孔孔径得到的流场进行对比,确定最优孔径。设计出的水冷滚筒样机性能通过了现场试验,电解铅阴极板的结板厚度与均匀度均满足生产要求。

Water-cooling roller is the core components of the production of negative plate of electrolytic lead, and the thickness and uniformity of negative plate of electrolytic lead is determined by flow field of internal cooling water of water-cooling roller. In order to catch the distribution of flow field inside of water-cooling roller and guide the designation of it, the moving reference frame technology in fluent software is used to numerically simulate the 3d flow in water-cooling roller and display the characteristics and state of the flow inside the water-cooling roller Intuitive. The optimal aperture of water hole is obtained through the contrastive analysis of simulation of different apertures of water holes. The performance of water-cooling prototype meets the requirements of field investigation, also the thickness and uniformity of negative plate of electrolytic lead meet production requirement.
