The main reasons of static electric explosion accidents in polyolefin plant silos were analyzed in this paper,and the study finds that the reasons include control failure of flammable gas content in the feed,high electrification caused by the wind supply,and frequent electrostatic discharge in silos.The electrostatic-reducing technologies of polyolefin powder were introduced,and its application performance in polyolefin plant silos was also clarified.In addition,the methods including FDCS and DGES for evaluation of electrostatic explosion in polyolefin plant silo were proposed.In the end,the risk of electrostatic explosion in PE plant blended silo was evaluated before and after application of electrostatic reducing technology.
