洗煤厂罗茨鼓风机房室内外噪声治理

摘要

介绍了凤凰山矿洗煤厂罗茨鼓风机房内外采用先进的噪声控制技术，有效地降低了罗茨鼓风机及周围的环境噪声。通过现场试验测定分析：采用隔声、吸声、消声等综合治理措施，机房内外的噪声及机房温度与制定目标基本一致，治理效果明显，取得了较好的社会效益和环境效益。%The noise produced by Roots blower was effectively reduced withadvanced noise control techniques in the coal washing plant of Fenghuangshan Mine. The on－ the－ spot test, measurement and analysis show that the use of comprehensive noise control techniques such as sound insulation, sound absorption and noise abatement can basically keep the noise level inside and outside the blower room and the room temperature in consistent with the preset targets, and has marked control effect, thus obtaining better social and environmental benefits.
