摘要
以西气东输豫皖管理处4座压气站为例,测量管道实际出站温度,得出了压气站出站温度影响农作物生长的事实。分析了通过改变冷却风扇的运行方式以降低出站温度这种传统方法的不足,提出了增加隔热层来降低出站温度对农作物生长影响的新方法。建立了管道隔热层模型,计算得出隔热层厚度宜为0.23m,通过对比分析可知,每座压气站3年赔偿百姓的费用即超过了其增加隔热层的费用。最后,对于国内新建及已建压气站如何增加隔热层提出了合理建议。
Taking the four gas compressor stations, under the jurisdiction of Henan-Anhui Management Office, PetroChina West-to-East Gas Pipeline Company, as an example, investigation and analysis are made to determine the impact of outlet temperatures of gas compressor station on the local crop growth around the pipeline. It is pointed out that the traditional method to reduce the outlet temperature by means of changing the operating mode of cooling fan has shortcomings. A new method to reduce the outlet temperature of gas compressor station by means of applying thermal insulation has been proposed to mitigate the impact on the local crop growth. The pipeline insulation is modeled and the best thickness of insulation is turned out from calculation as 0.23 m. It is known from comparison and analysis that the expenses for claim compensation to the local peasants in three years for each gas compression station are more than the cost of insulation addition. Finally, a rational suggestion is proposed on the procedures for insulation application in the existing and newly- built gas compressor stations. （6 Figures, 4 References）
