【摘要】 延庆新北城区欲利用地热资源进行地热集中供暖,拟采用"地热水+高温热泵"技术,并利用锅炉进行调峰,供暖尾水的回灌方式加以实现。为此,在分析该项目地热、水文地质条件的基础之上进行了该区地热资源量(水量及热量)的计算,并由此确定项目欲达到冬季供暖效果所需资源量及所需井数,并与地下赋存的资源量进行客观地对比分析,认为此项目供暖所需的资源量只占地下所赋存的资源量的很小一部分,加之夏季地下热水恢复期较长,使得地下所赋存的资源量足以满足该项集中供暖的需求,从而进一步说明该项目进行集中供暖是可行的,为保障在该区进行集中地热供暖提供了较为可靠的科学依据。更多还原

【Abstract】 The Yanqing County Government plans to utilize geothermal resources for the centralized heatsupplying system in the New North Downtown. It will adopt the technology of "geothermal water + high temperature heat pump", which may be implemented by boiler’s balancing the temperature, and by heatsupplying tail water re-injecting into groundwater. Therefore, on the basis of the analysis on the geothermal and hydrogeology condition, the geothermal resources quantity in this region(water yield and heat quantity) is calculated, thus the resource quantity and the required numbers of wells are determined for the purpose to achieve the heat-supplying effect in winter. By analyzing the quantity of the geothermal resources, it suggests that the resources quantity for heat-supplying just covers a small part of the geothermal resources. Together with the long recovery period of underground hot water in summer, it makes the quantity of geothermal resources to be enough to meet the demands of centralized heat-supplying; the project for centralized heat-supplying is feasible; and it is a relatively reliable scientifi c plan for the centralized heat-supplying in the New North Downtown of Yanqing County.更多还原
