摘　　要：为了配合解决煤矿综采、综掘工作面粉尘浓度居高不下的问题,提出了一种胶粘捕尘的新思路,利用风机将含尘风流抽入密闭装置,在装置内设置涂有胶粘材料的捕尘网,风流通过时,由于粉尘颗粒受到惯性、截留、布朗扩散运动的作用,从而被捕尘网捕获,达到了除尘的目的。设置了试验装置进行了试验,结果表明,安装5层捕尘网时,总除尘效率在90%以上的时间可持续20 min。In order to solve the problem of high concentration of dust in fully mechanized coal mining and fully mechanized coal mining face, presents a new idea of gluing dust collection. The fan is used to draw the dust flow into the sealing device. Adhesive material dust net, air flow through, due to dust particles by inertia, trapping, Brown diffusion movement of the role, which was caught dust net capture,and reached the purpose of dust. The experimental results show that when the 5-layer dust net is installed, the total dust removal efficiency is more than 90% for 20 min.
