Description

一种智能复合型深井地热水气分离装置
技术领域
本发明主要用于深井地热水的水气分离和除砂,保证后续工程对深井地热水使用时的安全性与清洁度,并通过与变频水泵联动,控制水位。
背景技术
深井地热技术是今年来新兴的新能源行业,深井地热采出水中有时会含有一定量的天然气,其主要成分为甲烷,在目前的实际工程中,大部分采用地热水经机房系统换热后再采取分离的方式,由于这种分离技术简单,被大部分工程所采用。但地热水经机房系统换热后进行水气分离存在较大的安全隐患,由于甲烷是一种可燃气体,其爆炸极限为5%~15%,当机房内管道发生泄漏时,天然气也会随地热水泄漏出来,由于机房是相对密封的空间,当机房内天然气聚集到一定量时便会发生窒息或爆炸事故。
深井地热水中含有少量泥沙,在目前实际工程中采用专用的旋流除砂器,除砂器不仅占用安装空间较多,同时造成了地热水系统阻力增加,增加了运行费用。
发明内容
为避免现有技术的不足,本发明提供一种智能复合型深井地热水气分离装置。
本发明的技术方案是:一种智能复合型深井地热水气分离装置,包括排气口、内置旋叶片的罐体、地热水进水口、压力变送器、磁性翻柱液位计、带控制系统的变频器、地热水泵、砂袋和放砂阀,所述内置旋叶片的罐体上部安有排气口,所述内置旋叶片的罐体的下部装有砂袋,砂袋连至地下管道,且中间装有放砂阀,在所述内置旋叶片的罐体的一侧上方装有地热水进水口,在地热水进水口下方安有磁性翻柱液位计,在所述磁性翻柱液位计上部装有压力变送器,压力变送器通过带控制系统的变频器与地热水泵相连接。
所述压力变送器通过带控制系统的变频器与地热水泵相连接,连至后续系统。
本发明的优点是:工具操作方便、使用灵活,可大大保证了后续工程的安全性,减少危险系数,自动化程度高,制作简单,便于操作。
附图说明
图1为本发明的结构示意图。
其中1为排气口,2为内置旋叶片的罐体,3为地热水进水口,4为压力变送器,5为磁性翻柱液位计,6为带控制系统的变频器,7为地热水泵,8为砂袋,9为放砂阀,A为地下管道,B为后续系统。
具体实施方式
下面结合附图对本发明做进一步描述;
一种智能复合型深井地热水气分离装置,包括排气口1、内置旋叶片的罐体2、地热水进水口3、压力变送器4、磁性翻柱液位计5、带控制系统的变频器6、地热水泵7、砂袋8和放砂阀9,所述内置旋叶片的罐体2上部安有排气口1,所述内置旋叶片的罐体2的下部装有砂袋8,砂袋8连至地下管道A,且中间装有放砂阀9,在所述内置旋叶片的罐体2的一侧上方装有地热水进水口3,在地热水进水口3下方安有磁性翻柱液位计5,在所述磁性翻柱液位计5上部装有压力变送器4,压力变送器4通过带控制系统的变频器6与地热水泵7相连接。
所述压力变送器4通过带控制系统的变频器6与地热水泵7相连接,连至后续系统B。
其特点当深水地热水进入此装置时,地热水在罐体2内部的旋叶片的作业下内部含有的砂砾进入下端的砂袋8内,同时地热水含有的天然气上升,通过上端的排气口1排出。在罐体2外部安装有磁性翻柱液位计5和液位变送器,一方面可以随时观察罐体2内部水位,另一方面液位变送器为变频器6提供的0~20mA信号,并通过变频器6对地热水泵7水量进行调节。地热水泵7的最大流量大于深井地热水流量,通过变频器6可以控制水泵7的流量,当罐体2内水位超过液位计20%时,水泵7自动启动,当罐体2内部的水位增加时,变频器6也相应的增加频率,水泵7转速增强,流量增大。将罐体2内的水位控制在20%~80%之内。
当液位超过80%时,开始报警,方便工作人员对后续工程进行检查,有可能是后续管道堵塞等情况。对于砂袋8内储存的砂砾通过人工进行定期排除。此装置可以智能的控制罐体2内部的水位,既除去了深井地热水中的天热气和砂砾,也保证了机房设备的安全运行。
