Abstract

The invention relates to an underground water dissolved gas on-site sampling device. The on-site sampling device comprises a degassing bottle, a gas collecting bottle, a water supplementing bottle, a vacuum pump and an inflating pump. Three ports are arranged on the degassing bottle, a bottle plug is arranged on the first port and provided with a gas guide pipe, a gas bag is arranged at one end of the gas guide pipe, and the other end of the gas guide pipe is connected with the inflating pump; a second bottle plug is arranged on the second port and provided with a water guide pipe, one end of the water guide pipe stretches deeply into the degassing bottle, and the other end of the water guide pipe is connected with the bottom of the water supplementing bottle; a third bottle plug is arranged on the third port, an inner cavity in the third bottle plug is communicated with a vacuum pipe and a gas collecting pipe, the free end of the vacuum pipe is connected with the vacuum pump, and a gas collecting needle head is arranged at the free end of the gas collecting pipe and is communicated with the gas collecting bottle. The on-site sampling device is simple in structure, low in cost and convenient to operate and effectively degasses and collects gas dissolved in underground water, which is beneficial for assay research in the next step.

Description

Technical field [0001] The invention relates to the field of groundwater quality analysis, in particular to a groundwater dissolved gas field sampler for collecting dissolved gas of normal temperature groundwater and geothermal water. Background technique [0002] The content of dissolved gas in groundwater is of great significance for studying the source and circulation conditions of groundwater. At present, the commonly used sampling equipment includes membrane degassing device and vacuum degassing device, but they are generally bulky, expensive and inconvenient to operate. Summary of the invention [0003] In order to overcome the shortcomings, the object of the present invention is to provide an on-site sampler for dissolved gas in groundwater, which is low in price and simple in operation, and effectively collects dissolved gas in groundwater. [0004] The technical solution adopted by the present invention to solve its technical problems is: a groundwater dissolved gas field ...
