两种除尘系统在综采工作面应用对比

通过对支架自动喷雾系统和负压诱导除尘系统的对比,发现自动喷雾系统在使用过程中存在喷嘴易堵塞,红外线发射器、接受器工作性能不稳定,维护量大,费用高,喷雾雾化效果差等缺点。而负压诱导除尘系统,由于采用气水混合式喷雾,喷头产生的高速气雾射流可以在其周围形成一个负压区,并产生很大的雾团,将带尘的空气诱导到雾团内,将其湿润后进行降尘处理。最后从工作原理、关键部件、除尘效果、投资费用等方面对2套系统进行对比,认为综采工作面负压诱导除尘系统优于自动喷雾系统,用水量较少、除尘效果好、投资费用低、系统简单、易维护,是一种更好的综采工作面除尘系统。 The hydraulic pressure automatic spraying system has some demerits in operation process,such as frequent nozzle blocking,unstable working performance of infrared ray launcher and receiver working,poor atomization effect,high maintenance cost and the like.Due to adopting water-air hybrid spraying,the nozzle of negative pressure induction dedusting system generates highspeed aerial fog jet which forms one negative pressure area as well as one big fog cluster.The air mixing dust is induced into the big fog cluster,first wetted,then dedusted.The two systems are compared from the aspects of working principle,critical components,dedusting effect,investment cost and so on.The results show that the negative pressure induction dedusting system gets better effect with less water,smaller investment and maintenance cost
