Description

Technical Field

[0001] The utility model relates to the technical field of short-term precursor gas detection for earthquakes, in particular to hot spring gas collection and processing equipment used for earthquake prediction. Background Art

[0002] The formation of hot springs is related to the deep circulation heating of groundwater. Most of the spring water comes from deep underground, and contains minerals, trace elements and soluble gas components carried by groundwater flowing through the area. These components can effectively reflect the relevant information of rock mineral composition, magma activity, water, gas and organisms. Under normal circumstances, the chemical composition, flow rate, water temperature, pH and other dynamics of spring water are relatively stable within the natural fluctuation range. However, the change of rock state in the deep crust before the earthquake will increase the permeability of underground media such as rocks and fluids, thereby affecting some chemical components in hot spring water, affecting the quality of hot spring water and the composition of escaping gas. Therefore, the change of hot spring gas is often used in earthquake monitoring and prediction and earth science research. When predicting earthquakes through hot spring gas, it is necessary to collect hot spring gas and detect and analyze its composition changes. The collected hot spring gas often contains a large amount of water vapor, which needs to be removed. The existing technology usually uses low-temperature freezing to remove water vapor from hot spring gas, but water vapor is easy to accumulate in the air supply pipe after freezing into ice, resulting in blockage of the air supply pipe, requiring frequent deicing and maintenance, and it is not easy to achieve continuous hot spring gas change monitoring.

The hot spring gas delivered by the air inlet pipe 2 is divided into two routes for transportation in the air supply branch pipe 5 and then combined into one route at the air outlet pipe 3 for transportation to the external detection equipment. The rest of the air supply branch pipe 5 except the two ends is arranged inside the box body 1. A spiral coolant circulation pipe 9 is arranged on the outer surface of the air supply branch pipe 5 inside the box body 1.

There is a spiral coolant circulation pipe 9 on the outside of each air supply branch pipe 5, which can further increase the freezing rate, extend the freezing time of the hot spring gas, increase the water vapor removal rate, and prevent water vapor from entering the detection equipment and affecting the accuracy of the detection results.

[0024] A sealing tube 6 is sleeved on the outside of the coolant circulation pipe 9, and the sealing tube 6 seals the coolant circulation pipe 9 on the outside of the air supply branch pipe 5. The sealing tube 6 is made of a poor thermal conductor material, and cooperates with the box body 1 to seal the middle part of the air supply branch pipe 5 to reduce the temperature and transfer heat to the outside, thereby reducing the power resources consumed by the refrigeration equipment, etc., which is beneficial to energy saving and environmental protection.

[0025] A coolant inlet pipe 8 is provided at the top of the coolant circulation pipe 9, and a coolant return pipe 7 is provided at the bottom of the coolant circulation pipe 9.
