发布时间:2019-06-10 18:38
【摘要】:针对综采工作面传统的喷雾降尘措施存在的易堵塞、雾化效果差、覆盖范围小等不足,提出了一套防堵塞,易安装的气水喷雾降尘系统。分析了气水喷嘴的雾化原理,通过实验确定了单个喷嘴最佳雾化效果的气水压力比,根据现场实际情况设计了气水喷雾模块及过滤系统,并在综采面采煤机安装应用,取得了良好的降尘效果。
[Abstract]:In view of the shortcomings of traditional spray dust reduction measures in fully mechanized mining face, such as easy blockage, poor atomization effect and small coverage, a set of gas-water spray dust reduction system with anti-blockage and easy installation is put forward. The atomization principle of gas-water nozzle is analyzed, the gas-water pressure ratio of the best atomization effect of single nozzle is determined by experiment, the gas-water spray module and filtration system are designed according to the actual situation in the field, and installed and applied in fully mechanized shearer. Good dust reduction effect has been obtained.
