Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to a geothermal water gas detection device. Background Art

[0002] Geothermal water refers to groundwater with a temperature higher than that of the surrounding rock at the observation depth. The temperature at which water begins to boil under a certain pressure is called the saturation temperature. The deeper the geothermal water is buried, the higher the static pressure it is subjected to, and the corresponding saturation temperature is also higher. However, geothermal water may contain gases that are harmful to the human body, such as hydrogen sulfide (H2S) and carbon monoxide (CO). These gases may pose a serious threat to human health at high concentrations. At the same time, the discharge of geothermal water into the environment may have an impact on the ecosystem, especially the gases contained may affect the water quality and air quality. By detecting the content of these gases, the potential impact of geothermal water on the environment can be evaluated and corresponding environmental protection measures can be taken, so testing is necessary.

[0003] In the prior art, gas detection is usually performed by sampling, storing the gas in containers, and then transferring the gas to relevant experimental equipment for detection. The overall process involves a large time span, and as the sampling points change, the number of containers for storing gas will also increase, resulting in certain inconveniences in subsequent use. Therefore, the present invention proposes a geothermal water gas detection device to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to provide a geothermal water gas detection device, which has the advantage of being easy to use and can solve the problems in the prior art.

DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1-Figure 5As shown, this embodiment proposes a geothermal water gas detection device, including an outer shell 1, and a battery pack is also installed on the back of the outer shell 1 to improve the convenience of the device. In this embodiment, a reagent box 24 is installed at the front end of the outer shell 1, and an openable protective door is provided on the reagent box 24. The reagent box 24 is used to store the chemical reagents needed to be used, such as barium hydroxide solution, which can be used to measure the carbon dioxide (CO2) content in the gas. The principle is that carbon dioxide reacts with barium hydroxide to generate water-insoluble barium carbonate precipitation, and the generated barium carbonate precipitation is collected by filtering and other methods, and its mass is accurately weighed. According to the mass of barium carbonate, the mass or amount of carbon dioxide participating in the reaction is calculated using a chemical equation, thereby obtaining the carbon dioxide content in the geothermal water gas. For another example, zinc acetate absorbs H2S to form a precipitate, and then reacts with iodine under weak acidic conditions. The excess iodine is titrated with Na2SO3, and then a subsequent calculation is performed to obtain the H2S content in the geothermal water gas. The device provides a function of collecting geothermal water gas and providing a reaction container for gas detection in geothermal water.

[0023] The processing tank 2 and the gas storage tank 3 are respectively installed on the inner side of the outer shell 1 through the limiting assembly, and the processing tank 2 and the gas storage tank 3 are connected through the first connecting member. Figure 1 As shown, the treatment tank 2 and the gas storage tank 3 are arranged up and down, and the first connecting member includes two groups of symmetrically arranged first connecting pipes 22, on which electromagnetic valves are installed, and the first connecting pipes 22 make the treatment tank 2 and the gas storage tank 3 in a connected state. At the same time, two groups of symmetrically arranged adsorption inner cores 16 are installed in the treatment tank 2, and the adsorption inner cores 16 are filled with activated carbon. A diverter 17 is arranged between the two groups of adsorption inner cores 16, and the diverter 17 is connected to the treatment tank 2, and the position of the diverter 17 corresponds to the position of the input end of the treatment tank 2. For the processing tank 2, two groups of symmetrically arranged adsorption cores 16 are installed in the processing tank 2, and the adsorption cores 16 are filled with activated carbon. A diverter 17 is provided between the two groups of adsorption cores 16, and the diverter 17 is connected to the processing tank 2. The position of the diverter 17 corresponds to the position of the input end of the processing tank 2. When the gas enters the processing tank 2, it passes through the diverter 17 and is guided to the two sides of the processing tank 2 respectively, and then passes through the adsorption core 16. During the process, it is adsorbed by activated carbon to remove impurities and interfering substances to avoid affecting the detection effect. After that, it enters the gas storage tank 3 through the first connecting pipe 22. In the present embodiment, the gas storage tank 3 and the processing tank 2 are both made of stainless steel. At the same time, the processing tank 2 is divided into a left half tank body and a right half tank body, which are connected by threaded connection.

[0024] like Figure 1As shown, the limit assembly includes a fixed plate 13 and a movable plate 14, the fixed plate 13 is connected to the outer shell 1 through a bracket, one end of the movable plate 14 is installed with a threaded rod 15 through a bearing, one end of the threaded rod 15 passes through the outer shell 1 and is installed with a turntable, and the threaded rod 15 is connected to the outer shell 1 through a thread. In this embodiment, the fixed plate 13 is fixedly set, and the movable plate 14 is movable. When the gas storage tank 3 or the processing tank 2 needs to be removed, the staff can turn the turntable by hand to drive the threaded rod 15 to rotate, thereby separating the movable plate 14 from the tank body, and then making the tank body (gas storage tank 3 or processing tank 2) in an unlocked state. During this process, the staff needs to hold the tank body, and then after it is separated to a certain position, the tank body can be removed. In this embodiment, both the fixed plate 13 and the movable plate 14 are provided with grooves adapted to the end of the tank body, which are used to play a limiting role.

[0025] A top shell 4 is installed above the outer shell 1, and the top shell 4 is rotatably connected to the outer shell 1. Specifically, a connecting sleeve 25 is installed at the lower end of the outer shell 1, and the outer side of the connecting sleeve 25 is connected to the outer shell 1 through a bearing, so that the top shell 4 can rotate on the outer shell 1. A filter channel 5 is provided in the outer shell 1, and a filter core 6 is filled in the filter channel 5. The filter channel 5 is connected to the processing tank 2 through a second connecting component, such as Figure 1 As shown, the filter channel 5 is curved to prolong the time for gas to pass through in a limited space. After the device collects the gas generated by geothermal water, it is initially filtered through the filter core 6, and the effect of the initial filtering treatment is improved by prolonging the time for gas to pass through, and then enters the treatment tank 2 through the second connecting component.

[0026] The second connecting assembly includes a second connecting pipe 23, which is connected to the top shell 4 through a rotating joint. An electromagnetic valve is installed on the second connecting pipe 23. Both ends of the second connecting pipe 23 are connected to the processing tank 2 and the filter channel 5, and under the action of the rotating joint, the rotation of the top shell 4 will not affect the second connecting pipe 23.

[0027] A collecting component is installed on the outer shell 1, and the collecting component includes a built-in vacuum pump 11. The built-in vacuum pump 11 is arranged in the top shell 4. A telescopic tube 12 is installed at one end of the top shell 4, and one end of the telescopic tube 12 is connected to the input end of the built-in vacuum pump 11. A sampling joint is installed at the other end of the telescopic tube 12. The output end of the built-in vacuum pump 11 is connected with the filtering channel 5 through a pipeline. When working, it is necessary to collect geothermal water gas. Therefore, the design of the telescopic tube 12 is adopted. It is a hose and can be adjusted accordingly according to the actual collection position. During collection, the sampling joint is connected to the geothermal water sampling pipeline, and then the built-in vacuum pump 11 is started. The built-in vacuum pump 11 draws the gas in the telescopic tube 12 into the filtering channel 5, and then performs subsequent steps.

[0028] A T-shaped partition 7 is installed on the inner side of the outer shell 1, and a reaction outer box 8 is installed on both sides below the T-shaped partition 7. A reaction inner box 9 is installed on the inner side of the reaction outer box 8, and a titration port is opened on the reaction outer box 8. In this embodiment, the front end of the reaction outer box 8 is connected to the outside, so the reaction inner box 9 adopts a drawer-type installation method. During normal detection, the reaction inner box 9 is connected to the reaction outer box 8 by bolts to ensure its stability, and the titration port is located at the upper end of the reaction outer box 8, and is used to During the experiment, titration determination is carried out. Accordingly, there is a gap between the reaction outer box 8 and the upper end of the T-shaped partition 7, which can normally accommodate the staff's hand to reach in and carry out the titration experiment. Accordingly, a three-way shunt pipe 10 is installed at the lower end of the gas storage tank 3, and the two ends of the three-way shunt pipe 10 are respectively connected to the reaction outer box 8 on both sides. Therefore, the device provides two reaction containers, which can simultaneously carry out geothermal water gas detection under two different solvents. Solenoid valves are installed at both ends of the three-way shunt pipe 10 for easy control.

[0029] The upper end of the reaction inner box 9 is connected to the inner cavity of the reaction outer box 8. A baffle 18 is provided at one end of the reaction inner box 9, and the size of the baffle 18 is adapted to the reaction outer box 8. When the reaction inner box 9 is fully installed, the baffle 18 completely blocks the space at the front end of the reaction outer box 8. Furthermore, a butt ring 20 is installed at one end of the reaction outer box 8 through a spring telescopic member 19, and the spring telescopic member 19 is provided with several groups. In this embodiment, the spring telescopic member 19 is evenly provided with twelve groups. A sealing gasket 21 is installed on the butt ring 20, and the sealing gasket 21 is in contact with the baffle 18. A resistance force is provided to the butt ring 20 through the spring telescopic member 19 (after the reaction inner box 9 is installed, the spring of the spring telescopic member 19 is in a contracted state), so that the sealing gasket 21 is in close contact with the baffle 18 to prevent gas from leaking from the gap between the baffle 18 and the reaction inner box 9.
