| 摘 要： | 宁波台ZK03井气氡仪在2017年12月更新为BG2015测氡仪,2018年12月又增上ATG6138M痕量汞仪,两套仪器采用同一脱气装置,记录显示采用原系统气氡仪、气汞仪数据离散度大,分析原因是一方面该井流量逐年降低使原脱气装置显现弊端,由于设计缺陷集气室进水量小造成原出水口不能实现水封空气出现跑气现象;另一方面ATG6138M痕量汞仪设计有定时吸气功能,原装置液面与脱气口间距小,部分水汽吸入仪器,引起仪器工作不稳定。为此,该台进行针对性设计改造,监测数据显示此次改造解决了原脱气装置缺陷,取得良好的效果。

| Abstract: | In December 2017,the gas radon meter was upgraded to BG2015 emanometer.In December 2018,the ATG6138M trace mercury meter was applied in gas observation.The two sets of instruments used the same degassing device.The record shows that the data dispersion of the original system of gas radon meter and gas mercury meter is large.The reason of data dispersion is that the well flow rate is reducing year by year,which makes the original degassing device shows its drawbacks.Because of the design defect,the small water intake of the collecting chamber results in the phenomenon that the original outlet cannot realize the water-sealed so that making air run off.On the other hand,the ATG6138M trace mercury meter has a function of induction air in certain time.There are some water-gas inhaled into instruments in the original device because of the small distance between the liquid level and the degassing port,which causes instability of the instrument.For this reason,we carry out targeted design to solve the defects of the original degassing device.The monitoring data shows that the defects of the original degassing device have been solved. |
