提高煤矿降尘效率的湿润剂实验研究
|
摘要
为了研制高效煤矿降尘湿润剂,采用煤尘沉降法研究煤尘润湿性能并设计了湿润剂复配优选方案。利用自行搭建的喷雾降尘实验平台测定优选出的复配湿润剂对3种疏水性煤尘的降尘效率。研究表明湿润剂溶液对不同煤样的润湿性不会发生根本性改变;阴离子和非离子型湿润剂的润湿性能优于阳离子和两性离子型湿润剂;合适的湿润剂以一定比例复配可以达到最佳润湿效果。
In order to develop efficient coal mine de-dusting wetting agents, tests on coal dust wetting sedimentation were conducted to study the wettability and obtain an optimum mixture of wetting agents.With the spraying dust control experiment device developed, the dustfall results of the mixture of wetting agents acting on three kinds of hydrophobic coal dust samples were measured. The study shows that the wettability of wetting agents acting on different coal dust does not fundamentally change. The wettability of wetting agents composed of anionic or non-ionic surfactants is superior to the wetting agents composed of cationic or zwitterionic surfactants. Two proper wetting agents compounded in a certain proportion can reach an optimum wetting effect.
