摘要

摘要: 锌电解过程中会产生很多有害颗粒物和酸雾，对其进行有效控制能够改善车间内操作工人的职业健康以及周边的大气环境。以中试实验为背景，在传统电解系统的基础上进行了超声技术改造，考察了超声技术对锌电解过程中产生的颗粒物和酸雾的减排效果，并分析了超声技术对锌电解的生产指标（如电流效率、能耗、锌产品品质等）的综合影响。结果表明：超声技术的引入有利于抑制颗粒物和酸雾的产生，使其分别减少44.4%和51.4%。同时，超声技术能够改善部分生产指标，使电流效率增加了22.5%，电解能耗降低了39.6%。因此，超声技术从锌电解实际生产源头上对颗粒物和酸雾的减排效果十分显著，这为超声技术应用于锌电解实际生产中颗粒物的减排等方面提供了参考。

Abstract: The process of zinc electrolysis produced a lot of harmful particles and acid mist, effective controlling of these particles and acid mist could improve the occupational health of workers in the workshop and the surrounding atmospheric environment. Based on the pilot experiment, the ultrasonic technology was reformed on the basis of the traditional electrolysis system. The emission reduction efficiency of ultrasonic technology on the particles and acid mist produced in the process of zinc electrolysis was investigated, and the comprehensive influence of ultrasonic technology on the production indexes of zinc electrolysis was analyzed, such as current efficiency, energy consumption and zinc product quality. The results showed that ultrasonic technology could reduce the particulate matter and acid mist by 44.4% and 51.4% respectively. At the same time, the introduction of ultrasonic technology improved some production parameters: increasing current efficiency by 22.5%, and reducing electrolysis energy consumption by 39.6%. Therefore, ultrasonic technology had a significant effect on reducing particulate matter and acid mist from the actual production source of zinc electrolysis, which provided an effective basis for the application of ultrasonic technology in the actual production of zinc electrolysis to reduce the particulate matters.
