摘要:
为预防锂电池生产过程粉尘爆炸事故的发生，选取典型锂电粉尘为研究对象，使用粉尘云最小点燃能量测试系统、20 L球形爆炸测试装置，试验分析氧化钙对锂电粉尘惰化效果的影响。研究结果表明：在锂电粉尘中加入氧化钙，可明显提高粉尘云最小点燃能量。随着氧化钙添加比例的增加，混合粉尘云最大爆炸压力和最大压力上升速率逐渐减小，随锂电粉尘和氧化钙混合粉尘质量浓度的增加，混合粉尘云最大爆炸压力及最大压力上升速率呈现先增大后减小的趋势，但变化幅度不明显。研究结果可为指导锂电粉尘爆炸防治方法提供参考。
Abstract:
In order to prevent the dust explosion accidents during the production process of lithium batteries,the typical lithium battery dust was selected as the researched object,and the influence of calcium oxide on the inerting effect of lithium battery dust was analyzed by using the test system for minimum ignition energy (MIE) of dust cloud and 20 L spherical explosion test device.The results show that the addition of calcium oxide in lithium battery dust can significantly improve the MIE of dust cloud.With the increase of addition proportion of calcium oxide,the maximum explosion pressure and maximum rate of pressure rise of mixed dust clouds gradually decrease.With the increase in the mass concentration of mixed dust with lithium battery dust and calcium oxide,the maximum explosion pressure and maximum rate of pressure rise of mixed dust cloud increase first and then decrease,but the change amplitude is not obvious.The research results can provide reference for guiding the explosion prevention and control method of lithium battery dust.
