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。
針對綜採工作麵傳統的噴霧降塵措施存在的易堵塞、霧化效果差、覆蓋範圍小等不足,提齣瞭一套防堵塞,易安裝的氣水噴霧降塵繫統。分析瞭氣水噴嘴的霧化原理,通過實驗確定瞭單箇噴嘴最佳霧化效果的氣水壓力比,根據現場實際情況設計瞭氣水噴霧模塊及過濾繫統,併在綜採麵採煤機安裝應用,取得瞭良好的降塵效果。

To solve the problems existed in traditional spraying dust suppression measures ,such as easy blockage ,poor at-omization effect and small coverage ,a set of gas-water spraying dust-settling system featured by anti-clogging and easy installation is set up .First ,the atomizing mechanism of gas-water spraying is analyzed in this paper and then the pressure ration between gas and water for best atomization effect of each spray nozzle is determined through comprehensive experi-ment .Finally ,the gas-water spraying model and corresponding filtration system are built according to actual field condi-tions and they are installed and applied in shearers in fully mechanized coal faces ,which turn out to be beneficial to dust suppression .
