针对目前综掘面在采用综掘机内、外喷雾及抽出式除尘风机整体除尘效果不理想的情况,提出了综掘面封闭式除尘系统,该系统利用空气幕控尘原理有效地将粉尘控制在掘进机前方,且设备布置简单、操作方便;根据综掘面的产尘规律和设备、工艺特点,优化了空气幕喷嘴位置和数量、除尘风机吸尘口位置等参数;通过现场应用,验证了该封闭式除尘系统的设计科学、合理,能有效地降低综掘面的粉尘浓度。
In view of the current comprehensive mining surface in the use of fully mechanized mining machine, the outer spray and the overall dust removal fan dust removal effect is not ideal situation, put forward a fully mechanized mining face closed dust removal system, the system uses air curtain dust control principle effectively dust control In the front of roadheader, the equipment layout is simple and easy to operate. According to the law of dust production and the equipment and technology characteristics of the fully mechanized face, parameters such as the position and quantity of the air curtain nozzle and the position of the dust suction port of the dust collector are optimized. The design of the enclosed dust removal system is scientific and reasonable, which can effectively reduce the dust concentration on the surface of the comprehensive excavation.
