Abstract
本发明是一种干热岩(EGS)超长真空绝热采热装置,本装置由外管(1)、内管(2)、密封装置(3)、真空泵(4)、真空表(5)组成。外管(1)和内管(2)之间的环空抽成真空。本发明利用真空绝热技术,高效率地将干热岩体中的热能导出,运用于发电、供暖(制冷)等,实现低碳环保,高效节能,能源再生的社会价值。本发明是一种全新的开发利用干热岩的技术。
Description
技术领域
本发明属于干热岩(EGS)技术,尤其是涉及超长真空绝热采热装置。
背景技术
提取地热能,井管绝热是减少干热岩井注入及排出系统热损耗,提高热能利用效率的主要措施。传统热力管网一般采用玻璃棉、岩棉、膨胀珍珠岩、聚氨脂、橡塑、硅酸钙等,输热热损一般在每千米3摄氏度左右,这对于四五千米深的干热岩井热能利用而言,热损耗是较大的。岩棉制品本身在强度、使用寿命、尺寸稳定性方面存在不少缺陷,并且在低容重下,粉尘飞扬,严重危及环境。因此,积极寻求绝热性能好的真正节能、环保的新型绝热保温材料,是提高热能利用率,节约能源的有效途径。
二氧化硅气凝胶作为一种新型轻质纳米多孔绝热材料,双组分、低密度环氧树脂涂层也是新型的金属保温隔热材料,较传统的绝热材料,热损耗较小。但是在实际应用中,二氧化硅气凝胶的高度松脆性、有限透明度及高昂的价格因素限制其在工业领域的大规模应用;双组分、低密度环氧树脂涂层自身价格昂贵,喷涂技术要求严格,在干热岩井下管施工中,井口工具敲打撞击,钳牙卡咬漆面,难以避免给下管作业造成困难。
石油专用真空管,是采油专用低温保温管材,每一根真空管9米左右,用接头连接成管串,接头处不是真空,大大降低了绝热效果,管串下入井内,若有真空管破损丧失绝热效果,在地面上无法监测;价格也极其昂贵,是普通石油管材的三倍以上。因此,该绝热管不适应干热岩的开发利用。
发明内容
本发明的目的是提供一种较低成本,高效节能,热能利用率高,低碳环保提取利用地热能的干热岩(EGS)超长真空绝热采热装置。
为实现上述目的,本发明采取以下技术方案:步骤1:在建造好的干热岩井孔内,安装外管(1)。
步骤2:在外管(1)内安装内管(2)。
步骤3:在外管(1)与内管(2)底部的环空内安装密封装置(3)。
步骤4:在外管(1)与内管(2)顶部的环空内安装密封装置(3),在密封装置(3)上安装真空泵(4)和真空表(5)。
本发明由于采取了以上技术方案,其具有以下优点:1、绿色环保,无废气、废液、废渣排放,无粉尘颗粒物飞扬;2、无易燃、易爆装置,使用安全;3、内管外管均采用N80石油管材,耐腐蚀、耐高温、耐高压,使用年限可达70年以上,极大地降低了使用维修成本;4、采用石油钻井施工中安装石油套管的技术,技术成熟,成本低,效率高;5、采用真空绝热技术可以更好地减少热传导,热能损耗几近为零,可以极大地提高干热岩井的地热能利用率。
附图说明
图1为本发明的结构示意图
图1中(1)外管、(2)内管、(3)密封装置、(4)真空泵、(5)真空表。
具体实施方式
1、在建造好的干热岩井孔内,安装外管(1)。
2、在外管(1)内安装内管(2)。
3、在外管(1)与内管(2)底部的环空内安装密封装置(3)。
4、在外管(1)与内管(2)顶部的环空内安装密封装置(3),在密封装置(3)上安装真空泵(4)和真空表(5)。
5、启动真空泵(4),把外管(1)与内管(2)之间环空内的空气抽取干净,形成真空。
6、关闭真空泵(4),通过真空表(5)观测外管(1)与内管(2)之间环空内的真空况态,如发现环空内有空气渗漏,就再次启动真空泵(4)抽取。
技术特点:使用国际标准的N80 石油管材,采用真空绝热技术,并可通过真空表随时监测超长真空绝热采热装置的真空状态,随时抽取空气,使真空达到最佳状态,确保干热岩井管绝热效果,减少干热岩井注入与排出系统热损耗,有助于高效率地将干热岩体中的热能导出,实现低碳环保的社会价值。
