Abstract

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.
