Description

Technical Field

[0001] The utility model relates to the technical field of earthquake short-term precursor gas detection, in particular to an online dehydration treatment tube for hot spring gas detection. Background Art

[0002] An earthquake is a phenomenon in which the earth's internal medium (rock) suddenly breaks, releasing energy and generating seismic waves, causing the ground to shake. Special phenomena that appear before an earthquake and can indicate that an earthquake is about to occur are called earthquake precursors. These precursors are closely related to the occurrence and development of earthquakes, and are significantly different from natural changes under normal backgrounds. Hot springs are usually located near geological fault zones and have deep circulation systems that can sensitively reflect geothermal conditions and structural change information deep in the earth's crust. As an important object of earthquake underground fluid observation, it plays an indispensable role in my country's earthquake prediction practice.

[0003] The precursor anomalies of hot spring earthquakes are mainly manifested in abnormal changes in water temperature, flow, ion composition, gas composition, and other phenomena, as well as turbidity, bubbling, and other phenomena. Among them, the change of hot spring gas is an important indicator of geological movement. When an earthquake occurs, the composition of hot spring gas will change significantly. Therefore, by monitoring the composition and concentration of hot spring gas, the dynamics of the earth's crust can be effectively tracked, and key data support can be provided for earthquake prediction.

[0004] After collecting the hot spring gas, the hot spring gas has a high temperature and contains a large amount of water vapor, which will seriously affect the accuracy of the hot spring gas analysis. The high-temperature and high-humidity gas entering the detection equipment will affect its internal parts, shorten the overall service life of the equipment, and increase the detection cost of the hot spring gas. For this reason, we propose an online dehydration treatment tube for hot spring gas detection. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: an online dehydration treatment tube for hot spring gas detection, comprising a treatment tube 1, wherein both ends of the treatment tube 1 are respectively connected to an external gas collecting hood and an analysis device, and the gas collecting hood for collecting hot spring gas and an analysis device for analyzing hot spring gas, such as a gas chromatograph, are connected through the treatment tube 1.

[0021] An air inlet valve 2 is installed on the end of the processing tube 1 close to the gas collecting hood, and an air outlet valve 3 is installed on the end of the processing tube 1 close to the detection equipment. The air inlet valve 2 and the air outlet valve 3 are preferably electric valves commonly used in the prior art, such as solenoid valves, which are used to control the opening and closing of the air inlet end and the air outlet end of the processing tube 1, respectively.

[0022] A guide tube 4 is arranged on the lower middle side of the processing tube 1, and the guide tube 4 is interconnected with the interior of the processing tube 1 to form an air cavity 5. A number of condensation plates Ⅰ6 and condensation plates Ⅱ7 connected to external condensation equipment are evenly arranged on the inner surface of the air cavity 5. The collected hot spring gas is cooled by the condensation plates Ⅰ6 and Ⅱ7 arranged in the air cavity 5 under the drive of the external air pump. The temperature in the air cavity 5 is maintained below -10°C, which can quickly cool the hot spring gas passing through the air cavity. At the same time, due to the low temperature, the water vapor in the hot spring gas can be quickly condensed or freeze-dried to achieve the purpose of cooling, dehumidification and dehydration, which greatly improves the accuracy of hot spring gas analysis, is conducive to the in-depth study of earthquake early warning, and at the same time avoids the high-temperature and high-humidity gas from entering the detection equipment, prolongs the overall service life of the equipment, and effectively reduces the detection and analysis cost of hot spring gas.

[0023] Specifically, one side of condensation plate Ⅰ6 is fixedly connected to the inner wall of gas cavity 5, and the other side does not contact the inner wall of gas cavity 5; one side of condensation plate Ⅱ7 is fixedly connected to the inner wall of gas cavity 5, and the other side does not contact the inner wall of gas cavity 5; and the sides of condensation plate Ⅰ6 and condensation plate Ⅱ7 that contact the inner wall of gas cavity 5 are not on the same side. Condensation plates Ⅰ6 and condensation plates Ⅱ7 are alternately arranged on the inner side of gas cavity 5 in sequence. The gas passage formed by the staggered arrangement of condensation plates Ⅰ6 and condensation plates Ⅱ7 is a winding "S" shape, so that the hot spring gas can contact more with condensation plates Ⅰ6 and condensation plates Ⅱ7, prolonging the contact time, and condensing the water vapor in the hot spring gas onto the surfaces of condensation plates Ⅰ6 and condensation plates Ⅱ7 to form a solid state with maximum efficiency and maximum extent, thereby removing moisture from the gas by condensation or freeze-drying.

[0024] The preferred technical solution is that the lower surface of the guide tube 4 is provided with a drain pipe 9 connected to the inside thereof, and the drain pipe 9 is used to discharge the melted liquid on the condensation plate Ⅰ6 and the condensation plate Ⅱ7. Due to the long-term operation of the hot spring gas, a large amount of ice or water droplets will condense on the condensation plate Ⅰ6 and the condensation plate Ⅱ7, so regular deicing and dewatering are required. In addition, since the hot spring gas mainly detects H2, He, Rn, CO2, CH4, N2, O 2、 CO, C2H6, C3H8, C4H 10 , H2S, etc., among which H2S, C4H 10 The liquid discharged through the discharge pipe 9 can also be collected and then tested for the hot spring gas contained therein, thereby providing a reference for the detection of the hot spring gas and improving the accuracy of the detection result.

[0025] A drain valve 10 is provided on the drain pipe 9. The drain valve 10 is a normally closed valve and is opened only when liquid needs to be discharged. When the drain pipe 9 is opened to discharge liquid, the gas collecting equipment stops working, and the air inlet valve 2 and the air outlet valve 3 are also in a closed state.

[0026] Optionally, a heating device, such as an electric heating wire, can be provided on the condensation plate I6 and the condensation plate II7. When it is necessary to clean the ice on the condensation plate I6 and the condensation plate II7, the external condensing equipment including the air compressor is turned off, and after waiting for a period of natural temperature rise, the electric heating wire is turned on to quickly melt the ice and improve work efficiency.

[0027] The preferred technical solution is that the inner side of the guide tube 4 is provided with two guide slopes 8 inclined downward toward the middle, and the drain pipe 9 is arranged between the lowest ends of the two guide slopes 8. The lengths of the condensation plates I6 and II7 are adapted to the guide slopes 8. The melted liquid on the condensation plates I6 and II7 flows along the guide slopes 8 to converge at the drain pipe 9 so as to discharge it and carry out detection.

[0028] In a further preferred technical solution, the condensation plates I6 and II7 on both sides of the drain pipe 9 are inclined toward the drain pipe 9, as shown in FIG. Figure 3 As shown in the figure, the dotted line is the direction of liquid flow, and the melted liquid on the inclined condensation plates Ⅰ6 and condensation plates Ⅱ7 converges to a lower place along the guide slope under the guidance of the condensation plates Ⅰ6 and condensation plates Ⅱ7, and finally the liquid on both sides of the condensation plates Ⅰ6 and condensation plates Ⅱ7 can flow into the drain pipe 9.

[0029] According to a preferred technical solution, the processing tube 1 is provided with a temperature sensor 13 electrically connected to an external control system for detecting the temperature in the air chamber 5 and controlling the refrigeration power of an external condensing device so that the temperature in the air chamber 5 is maintained at -10°C to -20°C.

[0030] According to a preferred technical solution, two barometers 12 electrically connected to an external control system are provided on the processing tube 1. The two barometers 12 are respectively provided at the air inlet end and the air outlet end of the processing tube 1, and are respectively used to detect the air pressure at the air inlet end and the air outlet end of the processing tube 1. When liquid needs to be discharged, the air inlet valve 2 is closed first, and the external air pump continues to pump the gas in the processing tube 1. The air pressure at the air inlet end and the air outlet end is detected by the barometer 12 to detect the vacuum degree inside the processing tube 1. When the set value is reached, the external air pump and the air outlet valve 3 are closed, and then the drain valve 10 is opened to discharge the liquid through the drain pipe 9.

[0031] The various valves, barometer 12, temperature sensor 13, etc. used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, circuit connections, etc. are all well-known technologies and will not be described in detail here.

[0032] See also Figure 4 The utility model also provides another embodiment, which is substantially the same as the aforementioned embodiment, except that: two processing tubes 1 are provided, and the air inlet ends of the two processing tubes 1 are connected in parallel with the gas collecting connecting tube 11, and the gas collecting connecting tube 11 is connected to the external gas collecting hood, so as to send the gas collected in the gas collecting hood into the corresponding processing tube 1 for cooling and dehumidification treatment; two processing tubes 1 are provided so that they can work in turn. When one of them needs to melt frozen ice and discharge liquid, the air inlet valve 2, the air outlet valve 3 and the condensing device on the other processing tube 1 are opened, so that the other processing tube 1 continues to process the hot spring gas, so as to ensure the continuous operation of the hot spring gas collection and detection equipment, and further improve the accuracy of the detection result.
