摘要

Because of the high thickness of bug dust and high humidity in the air draft alleyway of axial flow ventilators,the former muffler used by Mine Jing Gezhnang is jammed.Based on the dampproof experiment,dustproof experiment and reasonable disposal to mufflers,the paper designs a new muffler that has simple structure and lesser resistance loss for chief ventilators,and it has well dampproof and dustproof effect.Testing and effect appraisal indicates that the new muffler controls the noise of chief ventilators in Jin Gezhuang Mine well and achieves advantageous effect,so the value of extensively populaizing and using it in China is great.
