[0002] In the process of geothermal resource development, soluble or insoluble geothermal gases are often produced together with geothermal water exploitation. These geothermal gases are information carriers of matter and energy inside the earth and are important objects of geothermal research. Geothermal gases mainly include constant gases such as CO2, H2S, H2, CH4, and rare gases such as He, Ne, Ar, and Kr. These geothermal gases come from deep in the earth and are not easily affected by hydrological processes near the surface. Collecting these geothermal gases is of great significance to the study of deep geological environment information. Therefore, a geothermal gas separation device is needed to separate geothermal gases for collection and concentration for subsequent research. Utility Model Content

[0017] Example 1

[0018] This embodiment provides Figure 1 and Figure 2A geothermal gas separation device shown in the figure comprises a vertical main cavity 1, the upper end of the left side of the main cavity 1 is connected with a water inlet pipe 2, the water inlet pipe 2 is provided with a water inlet valve 21, the lower end of the right side of the main cavity 1 is connected with a water outlet pipe 4, the water outlet pipe 4 is provided with a water outlet valve 41, an exhaust pipe 3 is vertically arranged in the main cavity 1, the lower end of the exhaust pipe 3 seals and passes through the bottom of the main cavity 1, the position of the upper end of the exhaust pipe 3 is higher than the position of the water inlet pipe 2, the exhaust pipe 3 is located outside the main cavity 1. The exhaust valve 31 is provided on the part of the main cavity 1. A disturbance device 5 is provided in the body 1, and the disturbance device 5 includes a rotating base 51 and a rotating blade 52. The rotating base 51 is sleeved at the lower end of the exhaust pipe 3 located in the main cavity 1, and the rotating blade 52 is fixed on the rotating base 51. After the disturbance device 5 is turned on, the rotating base 51 drives the rotating blade 52 to rotate freely on the rotating base through the internal power supply and electronic control system, so as to fully disturb the geothermal water, so that the gas in the geothermal water can be better dissipated. Among them, the number of blades of the rotating blade 52 is at least three.

[0019] When in use, the geothermal well extraction pipeline is connected to the water inlet pipe 2, and the water inlet valve 21 is opened. The geothermal gas-liquid mixture fluid enters the main cavity 1 through the water inlet pipe 2. Due to the effect of gravity, the liquid in the geothermal gas-liquid mixture fluid flows downward to the bottom of the main cavity 1, and the gas part in the geothermal gas-liquid mixture fluid moves upward to the upper part of the main cavity 1 and gathers. Then the disturbance device 5 is turned on, and the disturbance blades begin to rotate, driving the gas-liquid mixture fluid in the main cavity 1 to rotate. After being disturbed by the rotation, the fluid state becomes more turbulent, so that the gas in the mixture fluid can fully escape and move to the upper part of the main cavity 1. At the same time, since the liquid in the gas-liquid mixture has a greater specific gravity than the gas, the centrifugal force on the liquid is greater than that on the gas. Therefore, relative to the liquid, the gas is easier to escape from the mixture; when the geothermal gas gathers enough in the main cavity 1, it enters the exhaust pipe 3 from the pipe mouth at the upper end of the exhaust pipe 3. After squeezing out the air originally in the main cavity 1 and the exhaust pipe 3, the geothermal gas can be collected at the outlet of the exhaust pipe 3.

[0020] In summary, the utility model can quickly separate the gas from the liquid in the geothermal gas-liquid mixture, so that the geothermal gas can be better collected and concentrated for subsequent research.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
