CNG站压缩机的节能优化改造

Energy Saving Optimization Reconstruction of Compressor in CNG Station

压缩机吸气压力低会造成压缩机运行效率低,影响CNG站能耗。通过对华油公司下属华阳鸿运CNG站压缩机各级气缸的缸径进行改造,一级缸径Ф155 mm扩为Ф175 mm,二级缸径Ф102 mm扩为Ф105 mm,三、四级缸径Ф78 mm扩为Ф80 mm。对比分析改造前后的压缩机排气量和耗电量,得出改造后压缩机实际产能同比增加42%、节电率最高可达31.5%的结论。改造后压缩机安全运行,283 d即可收回改造费用。

Low suction pressure will cause inefficient operation of compressor and affect energy consumption. After optimizing cylinder bores at all levels in Huayang Hongyun CNG compressor station, the first cylinder bore amplifies from Ф 155 mm to Ф 175 mm. The second cylinder bore amplifies from Ф 102 mm to Ф 105 mm and both of the third and fourth ones amplify from Ф 78 mm to Ф 80 mm. After optimization, the actual capacity of the compressor increases 42%. The rate of power saving can reach 31. 5%. The investments can be recovered in 283 d.
