摘　　要：介绍了骨料生产线机制砂储库放料装车工艺及机制砂散装机、水除尘系统的工艺流程、选型计算及控制系统,并将水除尘系统与布袋除尘系统进行了对比分析。实际使用效果表明,“喷淋+干雾”的水除尘工艺,水除尘系统为机械与电气一体化自动控制系统,能够与装车系统实现连锁,具备吹扫功能,可以在冬季实现管道排空后吹扫,可自动调整喷嘴雾化量,精准控制物料含水率。水除尘系统投资相对较小,装机功率及电耗较低,是对现有机制砂储库除尘工艺的有益补充,能够提高骨料企业的粉尘污染治理水平。This paper introduces the unloading and loading process and bulk loader,processes flow of water dedusting system,model selection calculation and control system of the machine-made sand warehouse in the aggregate production line,and compares the water dust removal system with the bag dust removal system.The actual use effect shows that when the"spraying+dry fog"water dust removal process is adopted,the water dust removal system is a mechanical and electrical integrated automatic control system,which can be interlocked with the loading system.It has the purging function,which can realize the pipeline emptying and purging in winter,automatically adjust the atomization amount of the nozzle,and accurately control the moisture content of the material.The investment of water dust removal system is relatively small,and the installed power and power consumption are relatively low.It is a beneficial supplement to the existing dust removal process of mechanical sand storage,and can improve the dust pollution control level of aggregate enterprises.
