摘要
基于自行设计的立式环形流道连续流动静电聚结试验装置和高压/高频交流电源,较为系统地研究了电压、频率、脉宽比、电场停留时间等参数对W/O型乳化液中分散相水颗粒静电聚结特性的影响。结果表明:电场停留时间和电压是影响水颗粒聚结效果的主要因素;频率、脉宽比对水颗粒聚结效果影响较小,但对电能消耗产生重要影响。因此必须结合特定的乳化液,综合考虑聚结效果、处理效率和能量消耗,选择合理的操作条件。
Based on the self-designed continuous flow electro-coalescence experimental apparatus with vertical annular flow channel and high-voltage/high frequency AC power supply,the effects of electric field parameters including voltage, frequency, pulse width ratio and residence time in electric field, on the electrostatic coalescing characteristics of dispersed water droplets in water-in-oil emulsions were studied systematically. The experimental results showed that residence time and voltage were the major factors affecting the coalescing process of water droplets. Frequency and pulse width ratio play an important role for power consumption rather than coalescing process. Therefore, optimum operation conditions for a certain emulsion should be selected by considering the coalescing process, treating efficiency and power consumption comprehensively.
