摘要
针对散货装卸作业中粉尘污染严重,以及常规压力雾化喷雾降尘系统无效耗水量高的问题,提出在常规压力雾化喷雾降尘系统的基础上增加自动感应装置实现自动喷雾思路。对80万t/a皮带机生产线料斗喷雾降尘装置进行了自动喷雾降尘技术改造,环境监测数据和粉尘污染扩散数值计算结果表明,装卸粉尘的减排率达85.3%,粉尘减排量达9.76 t/a,抑尘效果明显,同时也取得了良好的经济效益。本成果可用于散货装卸作业喷雾降尘系统改造工程,具有良好的工业应用价值。
In order to solve the serious problem of dust pollution and large water consumption of spray and aspirating device with conventional pressure during the loading and unloading for bulk cargo,an auto-induction device was added on the traditional compression spray dust removal system to realize automatic spray.The technical transformation of the automatic spray dust removal device for unloading hopper was realized on an 800,000 t/a belt conveyor line.The environmental monitoring dates and numerical simulation of dust pollutant dispersion showed that the dust reduction rate was 85.3%and the dust recovery quality was 9.76 t/a.And the benefits of environmental protection and energy conservation are encouraging and bring about better benefit.The results can be used in the transformation project of spray dust removal system for bulk cargo handling and have good industrial application value.
