摘要
为提高锂离子电池安全性能与质量,设计基于高频气流的吹吸式除尘装置.以锂离子电池负极片、微米级铜粉为研究对象,与风刀和吸罩的除尘效果进行对比.当极片运行速度为0.3 m/s时,随着吹吸式除尘装置工作距离由2 mm增加到10 mm,粉尘去除率由97.04％下降至71.88％;当工作距离为2 mm时,随着极片运行速度由0.1 m/s增加至0.5 m/s,粉尘去除率由97.96％降低至95.29％.随着吹吸式除尘装置工作正压增大,除尘性能提高,工作正压为14 kPa时,在极片表面粉尘去除率达99.27％.与风刀和吸罩相比,吹吸式除尘装置能在较低的功耗下实现更高的粉尘去除率.
Abstract
In order to improve the safety performance and quality of Li-ion battery,a blowing and suction dust removal device based on high-frequency airflow is designed.The Li-ion battery anode plate and micron-sized copper powder are selected as the research object,the dust removal effect is compared with that of air knife and suction hood.When the plate running speed is 0.3 m/s,the dust removal ratio is decreased from 97.04％ to 71.88％ with the working distance of the blowing and suction dust removal device increase from 2 mm to 10 mm.When the working distance is 2 mm,the dust removal ratio is decreased from 97.96％ to 95.29％ with the running speed of the battery plate increase from 0.1 m/s to 0.5 m/s.With the increase of the working positive pressure,the dust removal performance is increased,the dust removal ratio on the surface of the electrode reaches to 99.27％ with the working positive pressure at 14 kPa.Compared with the air knife and suction hood,the blowing suction dust removal device can achieve a higher dust removal rate with lower power consumption.
