摘　　要：为了改善喷雾降尘技术对煤尘治理效果,提出磁性活化水降尘技术。以山西晋中市鑫鼎泰煤矿烟煤为例,通过接触角测量实验对单体表面活性剂进行优选及复配,并对复配的表面活性剂和水进行磁化测试,最后使用构建的巷道相似模型进行降尘实验并确定降尘效率。实验结果表明:阴离子表面活性剂SAS-60和非离子表面活性剂AEO-7复配效果最佳;最佳磁感应强度和磁化时间分别为4000Gs和50min。经实验及现场测量,磁性活化水喷雾降尘技术的全尘降尘率高达87%以上,呼尘降尘率均高达79.3%以上,相比纯水喷雾降尘技术,大幅提高了对粉尘的降尘效率。通过上述研究,揭示了磁化水接触角和表面张力展现多极值增减变化规律的机理,并建立了磁化水循环系统,使磁化效果更加稳定,为工作场所实际应用奠定基础。In order to improve the effect of spray dust control on coal dust,a magnetic activated water dust reduction technology was proposed.Taking the bituminous coal of Xindingtai Coal Mine as an example,the monomer surfactant was optimized and compounded through the contact angle measurement experiment;magnetization test of the compound surfactant and water was carried out;finally,dust reduction experiment was conducted in the constructed roadway similarity model and the dust reduction efficiency was determined.The results show that,the compound effect of anionic surfactant SAS-60 and non-ionic surfactant AEO-7 is the best.The optimum magnetic induction intensity and magnetization time are 4000 gs and 50 min respectively.According to the experiments and field measurements,the total dust reduction rate of magnetic activated water spray dust reduction technology is more than 87%,and the dust reduction rate of exhalation is more than 79.3%.Compared with the pure water spray dust reduction technology,the dust reduction efficiency is greatly improved.Through the above research,the mechanism that the contact angle and surface tension of magnetized water show the law of multi extreme increase and decrease is revealed,and the magnetized water circulation system is established to make the magnetization effect more stable and lay a foundation for practical application in the workplace.
