电流密度对氯碱工业离子膜电解槽传递特性影响
Influence of current density on transfer characteristics in electrolysis cell of chlor-alkali industry
摘要
Abstract
To investigate the influence of current density on transfer characteristics in the electrolysis cell of chlor-alkali industry, the fluid flow, heat and mass transfer of anode chamber at different current densities were simulated numerically using computational fluid dynamics software. The distributions of velocity, temperature and concentration in a grille of the anode chamber were obtained. Taking liquid circulation rate, maximum velocity near the membrane, temperature and concentration at the membrane surface as indices, the performance of the electrolysis cell at different current densities was evaluated. Liquid circulation rate and temperature of membrane surface increased and concentration of brine decreased with increasing current density. Under typical working conditions for current density of 4.5 kA·m−2, average temperature of the electrolysis cell and of the membrane surface were 86.39℃ and 87.40℃, respectively. Average temperatures of the electrolysis cell and the membrane surface could be maintained at the values of the typical working conditions by lowering inlet temperature of brine when current density increased.关键词
