摘要
河北涿鹿矾山地震台气氡观测系统采用鼓泡式水气分离装置并放置于地下室中进行气氡观测,常存在集气装置堵塞的现象。2023年4月由于地下室排水管道故障,脱气集气效果较差,造成测值降低且严重影响观测质量。为解决此问题,采用水泵定时自动向外抽水保证脱气集气装置正常集气,同时重新改进集气装置气路,减少了脱气集气装置易堵塞的问题。结果显示:观测数据变化动态较之前更加稳定,抗干扰能力明显提高,观测数据质量较改造前的有所提升。
The gas radon observation at Fanshan Seismic Station in Zhuolu adopted a bubbling water-gas separation device.We placed it in the basement to observe the gas radon,but the gas collection device was often blocked.In April 2023,due to the failure of the basement drainage pipeline,the poor gas gathering effect caused the measured value to decrease,which seriously affected the observation quality.In order to solve this problem,the water pump is used to pump water automatically at regular intervals to ensure the normal gas collection of the degassing gas gath-ering device.Correspondingly,the gas path of the gas gathering device is further improved,which resolves the problem of the easily-blocked degassing gas gathering device.The results show that the dynamic changes of obser-vation data are more stable than the previous data.Both the anti-interference ability and the observation quality are obviously improved.
