摘要
以探讨太阳池型钾石盐热溶槽的稳定性及下对流层钾离子溶解扩散动力学为目的,在实验室构建太阳池型钾石盐热溶槽,检测运行中溶液密度、温度、钾离子浓度。试验结果表明,底部固体钾石盐层的存在强化了太阳池型钾石盐热溶槽稳定性,获得了K+在太阳池型热溶槽运行中的溶解扩散动力学方程。
In order to study the stability and the kinetics of the dissolution and diffusion of potassium salt in the lower troposphere of the solar pond type potassium salt hot solution tank,a solar pond type potassium salt hot solution tank was constructed in the laboratory to detect the solution density,temperature and potassium ion concentration in operation.The experimental results show that the existence of solid potassium salt layer at the bottom enhances the stability of the solar pond type potassium salt hot solution tank,and the kinetic equation of K+dissolution and diffusion in the operation of the solar pond type hot solution tank is obtained.
