【摘要】 河北怀来后郝窑地震台气氡观测系统采用溅落式脱气装置进行定点连续观测,由于水温较高且观测室温差较大,常出现冷凝水堵塞气路的现象,同时在更换干燥剂过程中,气路中待测气体与空气混合,这严重影响曲线动态,造成数据内在质量降低。为解决此问题,对怀来台气氡干燥装置进行改造:在增加气水分离瓶的基础上,将原干燥管更换为干燥塔,这有效地将气体进行缓冲和干燥;改造后,更换干燥剂的频次降低且抗干扰能力增强,气氡观测数据未再出现偏离背景值的情况,数据内在质量得到提高,改造效果较为理想。更多还原

【Abstract】 The gas radon observation system at the Houhaoyao seismic station in Huailai,Hebei Province,uses a sputtering degassing device for continuous observation.Due to the high water temperatures and significant temperature fluctuations within the observation room,the gas pathway is frequently blocked due to the condensed water.Specifically,during the replacement of the desiccant,the gas within the gas pathway is measured with mixed air,which significantly affects the curve dynamics and reduces the internal quality of the data.In address this issue,the radon drying device at Huailai was reformed.By incorporating a gas-water separation bottle,the volume of the drying tube was expanded,and the original drying tube was replaced with a drying tower,enabling efficient gas buffering and dehydration.Following the transformation,the frequency of desiccant replacement decreased,whereas the anti-interference ability was enhanced and the observed radon data no longer showed high values deviating from the background values,both the internal data quality and the observation quality were improved.更多还原
