矿井水余热利用技术在赵固一矿的设计与应用

为了解决矿井目前采用燃气锅炉供暖燃气费用高、氮氧化物超标以及燃气紧缺的问题，有效替代锅炉，充分实现节能减排，对一些具有丰富矿井水资源的矿井，在项目可行性论证的基础上，提出了采用热泵技术实现矿井水余热资源利用的解决方案。介绍了热泵工作原理和技术参数，对系统方案和设备组成、机组配置进行研究，然后对矿井水余热系统运行费用和采用燃气锅炉运行费用进行了分析对比。研究得出，采用矿井水余热利用经济，比燃气锅炉每年节约费用269.41万元，2.6年即可收回成本，经济效益显著。在降低煤矿生产成本同时，减少了环境污染，满足矿井冬季供暖、夏季制冷以及日常洗浴用热水的需求，实现替代锅炉，具有一定的推广应用价值。

Design and application of mine water waste heat utilization technology in Zhaogu No.1 Coal Mine

In order to solve the problem that the mine currently uses gas boilers to heat gas，the nitrogen oxides exceed the standard and the gas shortage，effectively replace the boiler and fully realize energy conservation and emission reduction.For some mines with rich mine water resources，based on the feasibility study of the project.A solution to realize the utilization of mine water residual heat resources by heat pump technology was proposed.The working principle and technical parameters of the heat pump were introduced.The system scheme，equipment composition and unit configuration were studied.Then the operation cost of the mine water waste heat system and the operating cost of the gas boiler were analyzed and compared.The study concluded that the use of mine water waste heat utilization economy，the annual cost savings of gas boilers was 269 410 00 yuan，and the cost can be recovered in 2.6 years，with significant economic benefits.While reducing coal mine production costs，it reduces environmental pollution，meets the needs of mine winter heating，summer cooling and daily bathing hot water and realizes alternative boilers with certain promotion and application value.
