节能技术在冻结站的应用

Energy Saving Technology Applied to Ground Freezing Station

矿井冻结法施工,电能消耗成本通常占项目成本的1/3左右。矿井冻结站整个制冷过程可分为氨循环系统、盐水循环系统和冷却水循环系统,这3个循环系统均以电能为动力。根据冻结法施工特点,探讨了3个循环系统设备选型、安装工艺,以及冻结站运行管理等方面可采取的节能措施。并通过工程实例,说明了节能带来的经济效益。

In a construction with a mine freezing method ,an electric power consumption cost would take about 1/3 of the project cost.A w hole refrigeration process of the mine freezing station could be divid-ed into an ammonia circulation system ,a brine circulation system and a cooling water circulation sys-tem.All those three circulation systems would be based on an electric energy as a power.According to the construction features of the ground freezing method ,energy saving measures applied to the equip-ment selection of the three circulation systems ,installation technique ,operation management of the freezing station and others were discussed.The engineering cases were applied to show the economic benefits from the energy savings.
