为了能使除尘用水的性能满足防治煤尘的要求,通过选取不同浓度的表面活性剂进行水特性的复配研究,得出了水雾化效果、表面张力与不同表面活性剂及复配质量分数之间的关系。其研究结果表明:在复配表面活性剂质量分数为0.04%且阴离子型活性剂A与非离子型活性剂B的质量比为4:2时,对水特性的影响程度达到最大,其适合捕捉呼吸性粉尘的雾滴百分比达到69%左右,经高庄煤矿综放工作面现场应用,除尘效率达到了85%以上,大幅度改善了井下的工作环境。
In order to make the performance of dusting water meet the requirements of coal dust prevention and control, by selecting different concentrations of surfactants to study the compounding of water characteristics, the results of water atomization, surface tension and different surfactants and compounding mass fraction The relationship between. The results show that: when the mass fraction of surfactant is 0.04% and the mass ratio of anionic surfactant A to nonionic surfactant B is 4: 2, the influence on the water property reaches the maximum, which is suitable for capturing Respirable dust droplet percentage reached 69%, by Gaozhuang coal mine fully mechanized caving face application, dust removal efficiency reached more than 85%, a substantial improvement in the underground working environment.
