摘要
煤矿井下大多存在粉尘浓度超标问题,不仅影响正常工作,更会给矿井安全带来极大的安全隐患。新型湿式除尘装置利用工作面管网中的压风和压水,通过喷头形成射流,产生负压,引导含尘气流进入捕尘管道实现有效除尘。合理的喷头结构可增加喷雾锥角,提高除尘效率。
Overweight of dust concentration is a common problem happened in most coal mine ,that not only affects workers' normal work ,but also brings a great potential safety hazard to mine.New wet duster' operating principle is that wind pressure and water pressure which generated in working surface pipeline network go through the nozzle jet and produce negative pressure leading the dust into dust catching pipe, and then the dust removed. The appropriate shower nozzle structure can increase spray's cone Angle, then the dust removal ability will be improved.
