胶带机转载点煤尘自动监测与喷雾降尘技术研究

 针对袋装煤矿胶带机转载点附近粉尘污染严重的实际问题，本文设计了胶带机转载点煤尘自动监测与喷雾降尘系统。设备采用先进的煤炭在线湿度测量技术，自动监测皮带运载煤炭的湿度，根据煤炭湿度的大小合理控制洒水喷雾量，实现干洒湿不洒，在确保防降尘效果的同时大大降低了用水量，克服了以往因洒水过量造成皮带打滑、运输巷道积水等一系列问题，实现了井下防降尘智能、高效、合理的目的，在现场应用中取得了良好的效果。

Study on the Automatic Monitoring and Spraying Dust-settling Technology at the Transfer Point of Belt Conveyors

According to the practical problems of severe dust pollution near the loading point, the paper designed the automatic monitoring and spraying dust-settling system at the transshipment point of belt conveyors. The equipment, using the advanced Coal-line moisture measurement, monitored the coal moisture on the belt conveyer automatically. Then we can realize automatic sprinkling when the coal is dry and not when the coal is wet through sprinkler water application controlling. In this way, we could ensure dust-laying effect while water consumption was greatly reduced. It overcame a series of questions such as belt sipping and hydrops in transport tunnel because of the excessive water spraying. This equipment has been applied in coal mine for practical research and achieved good effect.
