| 中文摘要: |
| 浅层地温能作为绿色新能源,近年来在越来越多的地区得到开发与应用,通过对龙口市主城区展开水文地质调查、地温场调查、现场热响应试验及热物性试验等工作,查明了工作区浅层地温能的赋存条件,得到了地埋管型地源热泵的开发利用潜力分区,并通过等效计算获得浅层地温能开发利用经济、环境效益价值。根据调查与计算分析可知:考虑土地利用系数时,(1)工作区地下水换热系统夏季可制冷面积1082.00×104 m2,冬季可供暖688.55×104 m2；地埋管换热系统夏季可制冷面积1573.43×104 m2,冬季可供暖1677.81×104 m2。(2)浅层地温能开发利用总能量为755.79×104 GJ/a,折合标准煤15.06×104 t/a,节煤量43.04×104 t/a,热资源价值10543.51万元/a。(3)可减少排放氮氧化物、二氧化硫、二氧化碳、悬浮质粉尘、生成煤灰碴等总计37.91×104 t/a,节省污染治理费4249.03万元/a。 |

| As a new green energy, shallow geothermal energy has been developed and applied in more and more areas in recent years. Based on the hydrogeological survey, ground temperature field survey, field thermal response test and thermal physical property test in the main urban area of Longkou, the occurrence conditions of shallow ground temperature energy in the working area are found out, and the development and utilization potential zoning of underground water type and underground pipe type ground source heat pump are obtained. The economic and environmental benefits of shallow geothermal energy development and utilization are obtained by equivalent calculation. Through the research, we can know that when considering the land use coefficient:(1) The cooling area of the underground water heat exchange system in the working area is 1082.00×104 m2 in summer and 688.55×104 m2 in winter. The cooling area of the buried pipe heat exchange system is 1573.43×104 m2 in summer and 1677.81×104 m2 in winter.(2) The total energy of shallow geothermal energy development and utilization is 7557900 GJ/a, equivalent to 150600 t/a of standard coal, 430400 t/a of coal saving, and the value of thermal resources is 105.4351 million yuan per year.(3) It can reduce the emission of nitrogen oxides, dioxygen sulfur, carbon dioxide, suspended dust, coal ash slag, etc. by a total of 379100t/a, and save the pollution control fee of 42.4903 million yuan per year. |
