摘　　要：为降低生物降解树脂中的粉尘含量,文章对产生粉尘和絮状物的原因及影响因素进行分析。通过分析粉尘的组成形式和存在方式,借鉴干燥流化床原理,采用卧式密闭除粉器对成品包装系统进行设备技术改造。技术改造后,对除粉器投用前、后对粉尘清除的情况进行对比分析。研究结果表明,改造后粉尘清除率可达99.5%,絮状物清除率达95.0%。研究结果可有效清除切片输送过程中产生的粉尘、絮状物。To reduce the dust content in biodegradable resins,the article analyzes the reasons and influencing factors for the generation of dust and flocs.By analyzing the composition and existence of dust,and drawing on the principle of a dry fluidized bed,a horizontal sealed powder remover is used to carry out equipment technical transformation on the finished product packaging system.After the technical transformation,a comparative analysis was conducted on the dust removal before and after the use of the dust remover.The research results show that the dust removal rate can reach 99.5%and the flocculent removal rate can reach 95.0%after the transformation.The research results can effectively remove dust and flocs generated during chip transportation.
