The invention can be interconnected with an automatic gas-phase chromatograph so as to carry out on line inspection.

Description

technical field [0001] The patent of the present invention relates to a spray degassing device, in particular to a set of degassing devices used in pre-earthquake prediction to detect gas components in underground fluids using automatic gas chromatography and sensors, belonging to the technical field of degassing devices. Background technique [0002] The dynamic observation of underground fluids has been one of the main precursor methods for exploring the early prediction of earthquakes at home and abroad for many years. Some dissolved gas components of underground fluids, such as hydrogen, oxygen, helium, argon, carbon dioxide, nitrogen, methane, hydrogen sulfide, etc. An important part of the foreshadowing. The instruments for detecting these dissolved gases, such as gas chromatographs and sensors, are more suitable monitoring methods. How to convert the dissolved gases in the underground fluid into gaseous samples and send the gaseous samples to analytical instruments su...

Problems solved by technology

[0003] Many patents related to degassing technology have been applied for and published, but most of the degassing devices cannot realize automatic measurement, such as the utility model patent of the group, the patent number is ZL02217830. "It uses vacuum, stirring and heating technology. Although the degassing efficiency is very high, it is manually operated. Currently, the device that realizes continuous automatic degassing, such as the utility model patent applied by the Fujian Provincial Seismological Bureau, the patent number is ZL02228947.X , the patent name is "Dissolved Gas Quantitative Degassing Device", which includes a diffuser and a bubbling degassing circulation line, which can prepare a quantitative volume of gaseous samples of related dissolved gas components that establish a dissolution equilibrium relationship with the measured water sample

Although the balanced dissolution degassing system and stirring heating system developed at present can achieve the purpose of automatic degassing monitoring, they have the disadvantages of too much water vapor during the heating process, it is difficult to dry completely, and there are many valves, complex structure, and complicated operation.

Membrane degassing devices have the following disadvantages: some degassing membranes take a long time to degas, and some degassing membranes are difficult to control the separation of water vapor, so the reproducibility of the experimental process is poor. The membrane is relatively easy to pollute, and the degassing membrane is cleaned or replaced at regular intervals, and the device needs frequent maintenance. There are also many tests on other systems such as automatic dissolution and degassing of underground fluids, but there are also complex structures and water vapor generated after the heating process, etc. question
