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 dust concentration in fully mechanized coal mining face and fully mechanized mining face, a new idea of glue dust catching and dust collection is put forward. The fan is used to draw the dust-laden wind into airtight device. In the device, Materials of the dust-catching network, when the Merry passes, due to the inertia of dust particles, interception, Brown diffusion movement, which is captured by the capture net, to achieve the purpose of dust. The test device was set up and tested. The results show that when the 5-layer dust-catching net is installed, the total dust removal efficiency can be maintained for more than 90% of the time for 20 min.
