城区天然气配气站噪声的产生及防治

城区天然气配气站噪声超标已成为供气部门亟待解决的难题,文章分析了配气站噪声污染现状,指出噪声产生原因主要为天然气流动,供气量增长使设备超负荷运行等7个方面。分别针对现有配气站和新建、改扩建站场提出降噪措施,指出设备在额定范围内运行、气体流速控制、工艺改造等是噪声控制的重要手段。并对城区天然气配气站噪声治理的进一步研究提出了建议。

Noise Generation and Its Control of Gas Distribution Stations in Urban Area

Noise pollution of gas distribution stations in urban area were an urgent problem to be solved. Noise pollution status of the stations was analyzed. Seven aspects of the stations were pointed out to be the main reasons of the noise pollution sources including gas flow and equipment overload etc. Noise control measures were put forwarded for the new stations and rebuilding and extending stations including rated load work, velocity of gas flow control and technology modification. At last, further research directions of the station noise control were suggested.
