煤矿输送带运输自动除尘系统的设计
|
摘要
针对传统除尘方法除尘效果不明显、维护费用高、劳动强度大的特点,通过对自动喷雾除尘技术方法的研究,设计了煤矿输送带运输自动除尘系统。通过除尘实施,充分利用输送带的动能,运输系统开始工作即可启动除尘系统,产生压力水和压力气,水和气通过一种广角紊流雾化喷头喷出,产生浓雾,除尘过程无需外接电源,自动化程度高,除尘及时,且喷头不易堵塞,除尘效果得到极大提升。
In view of the characteristics of the traditional dust removal method, such as no obvious dust removal effect, high maintenance cost and strong labor intensity, through the research of the automatic spray dust removal technology,the automatic dust removal system for the belt conveyor of the coal mine was designed. Through the implementation of dust removal, making full use of the kinetic energy of the belt, the transportation system can start the dust removal system at the beginning of work, generating pressure water and pressure gas. Water and gas are ejected through a wide-angle turbulent atomizing nozzle, generating dense fog. There is no need for external power supply in the dust removal process,with high automation, timely dust removal, and the nozzle is not easily blocked. The dust removal effect has been greatly improved.
