Description

Technical Field

[0001] This invention belongs to the field of associated gas measurement technology, specifically relating to a device for high-precision and rapid determination of associated gas content in geothermal water. Background Technology

[0002] The extracted water from deep geothermal wells contains a certain amount of gas, the main component of which is methane. This gas will leak out along with the extracted geothermal water, directly affecting the safety and environmental impact of geothermal development.

[0003] In existing technologies, geothermal water is mainly collected through sealed sampling bottles, and the gas composition is analyzed in the laboratory using gas chromatography (GC) or mass spectrometry (GC-MS). This method is time-consuming and cannot achieve rapid and timely detection. To improve the detection speed, high-temperature evaporation of geothermal water is usually used to separate the associated gas from the geothermal water. Although this method can quickly separate and detect the gas, the water vapor and associated gas are in a straight tube or simple coil condenser. Due to the limited contact area, short gas flow path, and insufficient residence time, the water vapor is not fully condensed. Residual moisture can easily enter the downstream with the gas, interfering with the analysis or damaging the instrument. Moreover, under low-speed laminar flow, the condensate can easily form a continuous liquid film or accumulation on the tube wall, hindering gas flow and leading to large errors in subsequent measurements. Summary of the Invention

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] Please refer to the following: Figures 1 to 4The present invention describes a high-precision, rapid device for determining the associated gas content of geothermal water. The device comprises an outer casing 1, a filter unit 2, an evaporator 14, a condenser unit 3, a vapor-condensing breathing mechanism 4, and a drying device 23. The top of the outer casing 1 has two mounting holes 13. A storage tank 11 is detachably connected to one of the mounting holes 13. The filter unit 2 is disposed within the outer casing 1 and communicates with the mounting hole 13. The evaporator 14 is disposed within the outer casing 1 and communicates with the filter unit 2 via a micro water pump. The condenser unit 3 is disposed within the outer casing 1 and has an inlet communicating with the evaporator 14, as well as an air outlet and a water outlet. The water outlet is connected to a water collection tank 22. The vapor-condensing breathing mechanism 4 is disposed within the outer casing 1 and has a collection section connected to the air outlet of the condenser unit 3, and multiple cooling flow sections. The outlet of the vapor-condensing breathing mechanism 4 communicates with each cooling flow section. The collection section is connected to each cooling flow section via the air guide valve seat 5. The gas condensation breathing mechanism 4 can alternately supply the associated gas in the collection section to each cooling flow section through the air guide valve seat 5, thereby disrupting the laminar flow boundary. The drying device 23 is installed in the outer casing 1 and is connected to the outlet of the gas condensation breathing mechanism 4. The drying device 23 is connected to another mounting hole 13 via the air supply pipe 1615.

[0047] In this embodiment, the other mounting port can be connected to the extraction pipe 12 to ensure that the dried associated gas is extracted to the detection module.

[0048] The working process is as follows: geothermal water is injected into storage tank 11. The geothermal water enters filter unit 2 through a channel connected to installation hole 13. Filter unit 2 removes suspended particles, mineral precipitates, and other solid impurities from the geothermal water, preventing clogging or contamination of subsequent components. Next, a micro-pump transports the filtered geothermal water to evaporator 14. Evaporator 14 heats the geothermal water, causing it to vaporize and releasing dissolved associated gas, forming a mixture of water vapor and associated gas. Then, the mixed gas enters condenser unit 3 through the inlet. Condenser unit 3 cools the mixed gas, condensing the water vapor into liquid water. The liquid water flows into collection tank 22 through the outlet. The initially separated associated gas enters the collection section of gas condensation breathing mechanism 4 from the outlet of condenser unit 3. Afterward, gas guide valve seat 5 alternately pressurizes the associated gas in the collection section into each cooling flow section, disrupting the laminar flow boundary, increasing the flow velocity of the associated gas, and simultaneously allowing the associated gas to be fully cooled within the cooling flow section, further removing residual moisture. Finally, the associated gas, after secondary cooling, enters the drying device 23, which performs deep drying on the associated gas. The dried associated gas is then connected to another mounting hole 13 through the gas supply pipe 1615, which facilitates subsequent extraction through the gas extraction pipe 12 to the detection module.

[0049] The high-precision, rapid device for determining the associated gas content in geothermal water provided in this embodiment, compared with existing technologies, utilizes a micro-pump to rapidly deliver filtered geothermal water to the evaporator 14, avoiding the time loss caused by the natural flow of geothermal water. The condensation unit 3 quickly condenses water vapor in the mixed gas, initially separating the associated gas, and simultaneously drains condensate. The aerosol breathing mechanism 4, in conjunction with the air guide valve seat 5, performs alternating pressure air delivery, accelerating the flow and cooling of the associated gas in the cooling flow section, shortening the cooling time, significantly reducing the overall detection cycle, and achieving a fast detection time. The efficient connection between the drying device 23, the aerosol breathing mechanism 4, and the air delivery pipe 1615 reduces the time for associated gas transmission and drying. The filtration unit 2 removes solid impurities from the geothermal water, preventing impurities from entering subsequent components and affecting the detection results. The effective condensation of water vapor by the condensation unit 3 reduces the interference of water vapor on the detection of associated gas. The aerosol breathing mechanism 4, through alternating pressure air delivery, disrupts the laminar flow boundary, preventing the formation of a continuous liquid film or accumulation of liquid on the pipe wall under low-speed laminar flow, thus reducing measurement errors and simultaneously ensuring sufficient cooling of the associated gas, further removing residual moisture. The deep drying by the drying device 23 ensures that there is no moisture interference in the associated gas.

[0050] In some embodiments, the outer casing 1 may be as follows: Figure 3 The structure shown. See also Figure 3 The outer casing 1 is provided with a heat insulation plate, which divides the internal space of the outer casing 1 into a heat insulation cavity and a pre-treatment cavity located above the heat insulation cavity.

[0051] The filter unit 2 and evaporator 14 are both located in the pretreatment chamber. The condenser unit 3, the vapor condensation breathing mechanism 4, the air guide valve seat 5, and the drying device 23 are all located in the heat insulation chamber.

[0052] In this embodiment, the condensing unit 3 can be connected to the evaporator 14 via the steam pipe 24.

[0053] The heat insulation plate divides the outer casing 1 into a pre-treatment chamber and a heat insulation chamber. In the pre-treatment chamber, the filter unit 2 filters the geothermal water, and the evaporator 14 heats and vaporizes the geothermal water, potentially generating heat transfer. Because the heat insulation chamber and the pre-treatment chamber are separated by the heat insulation plate, the plate effectively prevents heat transfer from the pre-treatment chamber to the heat insulation chamber, thus avoiding a temperature rise in the heat insulation chamber. Meanwhile, the condenser unit 3, the vapor condensation breathing mechanism 4, the air guide valve seat 5, and the drying device 23, located in the heat insulation chamber, can operate in a relatively stable and suitable temperature environment to ensure condensation effect, associated gas cooling efficiency, and drying quality.

[0054] In some embodiments, the condensation unit 3 described above may employ, as follows: Figure 3 , Figure 5 and Figure 6 The structure shown. See also Figure 3 , Figure 5 and Figure 6 The condensing unit 3 includes a mounting plate 31, metal tubes 33, connecting pipes 34, and heat exchange fins 32. Two mounting plates 31 are provided, arranged parallel and spaced apart. Multiple metal tubes 33 are provided, each arranged along the spacing between the two mounting plates 31, fixed to both plates, and extending out of each plate. Multiple connecting pipes 34 are provided, each connecting pipe 34 connecting to the ends of any two adjacent metal tubes 33. The connecting pipes 34 and the metal tubes 33 combine to form a serpentine cooling channel. Multiple heat exchange fins 32 are provided, spaced apart between the two mounting plates 31, and connected to each metal tube 33.

[0055] One end of the cooling channel is the inlet of the condensing unit 3, and the other end is the outlet of the condensing unit 3.

[0056] The water vapor and associated gas mixture generated by the evaporator 14 enters the serpentine cooling channel formed by the combination of metal tubes 33 and transfer pipes 34 through the inlet of the condenser unit 3. The plate frame 31 provides stable mounting support for the metal tubes 33 and transfer pipes 34, ensuring the stability of the cooling channel structure. As the mixed gas flows within the serpentine cooling channel, it makes full contact with the walls of the metal tubes 33. The heat exchange fins 32, connected to each metal tube 33, increase the heat exchange area between the metal tubes 33 and the outside environment, accelerating the transfer and dissipation of heat from the tube walls, thereby rapidly reducing the temperature of the mixed gas within the cooling channel.

[0057] It should be noted that the condensation unit 3 may also include an air-cooled structure, with the air-cooled structure facing each heat dissipation fin.

[0058] In some embodiments, the condensation unit 3 described above may employ, as follows: Figure 7 The structure shown. See also Figure 7 The condensing unit 3 is set at an angle, and there is a height difference between the two plate frames 31.

[0059] The bottom end of each connecting pipe 34 corresponding to the lower plate frame 31 is connected to a water guide pipe. Each water guide pipe is connected to an external connecting pipe 36, the outlet of which is the water outlet of the condensation unit 3.

[0060] The mixed gas flows within the serpentine cooling channel. After the water vapor condenses into liquid water, due to the inclined arrangement of the condensation unit 3 and the height difference between the two platen supports 31, the liquid water flows under gravity along the wall of the metal pipe 33 towards the lower platen support 31, eventually collecting in the transfer pipe 34 corresponding to the lower platen support 31. A water guide pipe connected to the bottom of the transfer pipe 34 provides a discharge channel for the condensate. The condensate flows through the water guide pipe into the outer pipe 36, and then exits from the outlet of the outer pipe 36 to the water collection tank 22. During this process, the inclined arrangement of the condensation unit 3 allows the condensate to flow naturally and smoothly, preventing its accumulation within the metal pipe 33 or the transfer pipe 34. The cooperation between the water guide pipe and the outer pipe 36 ensures that the condensate can be discharged quickly and orderly, without affecting the flow and condensation process of the mixed gas within the cooling channel.

[0061] The inclined design of the condensation unit 3 and the height difference of the machine plate frame 31 allow the condensate to flow naturally under gravity, eliminating the need for additional power to drive its discharge. This reduces equipment costs and energy consumption, while also preventing delays in condensate discharge caused by reliance on additional power. The cooperation between the water guide pipe and the external pipe 36 ensures rapid discharge of condensate, preventing it from accumulating in the cooling channel and hindering the flow of the mixed gas. This shortens the residence time of the mixed gas in the condensation unit 3, accelerates the overall testing process, and achieves a faster testing time.

[0062] Specifically, a pressure valve can be installed between the water inlet pipe and the external pipe 36. When the liquid level in the water inlet pipe reaches a certain height, the pressure valve will automatically drain water into the external pipe 36 to ensure that the water inlet pipe always maintains a liquid seal and prevent associated gas from flowing out.

[0063] In some embodiments, the above-described aerosol breathing mechanism 4 may employ, for example... Figure 6 The structure shown. See also Figure 6 The aerosol breathing mechanism 4 includes cooling pipes 41, an air supply chamber 42, and an exhaust pipe. Multiple cooling pipes 41 are provided, each arranged along the interval between two machine plate frames 31 and connected to each heat exchange fin 32. Both ends of each cooling pipe 41 extend out from the two machine plate frames 31. The cooling pipes 41 serve as the cooling flow section. The air supply chamber 42 is located on one side of the machine plate frame 31 at a higher position and is connected to the air outlet of the condensation unit 3. The air supply chamber 42 serves as the collection section. The exhaust pipe is connected to the outlet of each cooling pipe 41 and to the drying device 23.

[0064] The associated gas (still containing a small amount of residual moisture) initially separated by the serpentine cooling channel in the condensing unit 3 is discharged from the outlet of the condensing unit 3. Because the gas delivery chamber 42 is located on one side of the high-level machine plate frame 31 and is connected to the outlet, the associated gas naturally flows into the gas delivery chamber 42 for temporary storage. The gas delivery chamber 42 is sealed to prevent leakage of associated gas or mixing with outside air. Since the cooling pipes 41 are arranged along the interval direction of the machine plate frame 31 and connected to the heat exchange fins 32, the heat exchange fins 32 can transfer the low-temperature environment of the condensing unit 3 to the cooling pipes 41, so that the cooling pipes 41 maintain a stable low-temperature state. At the same time, the gas guide valve seat 5 delivers the associated gas in the gas delivery chamber 42 into each cooling pipe 41 at a preset rhythm. During the flow of the associated gas in the cooling pipes 41, it comes into full contact with the low-temperature pipe wall, and the residual water vapor is further condensed into liquid water.

[0065] The connection design between the cooling pipe 41 and the heat exchange fins 32 eliminates the need for an additional cooling device for the cooling pipe 41. It directly utilizes the low-temperature environment of the condensation unit 3 to achieve secondary cooling of the associated gas, reducing equipment start-up and shutdown time and energy consumption. The centralized design of the exhaust pipe avoids stagnation caused by the dispersed delivery of associated gas through multiple pipelines, ensuring continuous and stable airflow. The sealed design of the gas delivery chamber 42 prevents outside air from mixing into the associated gas, preventing errors in the detection results. The synergistic effect of the cooling pipe 41 and the heat exchange fins 32 ensures a uniform and stable temperature for the cooling pipe 41, preventing incomplete condensation of residual water vapor due to localized temperature fluctuations and reducing the amount of moisture entering the drying device 23.

[0066] In some embodiments, the aforementioned air supply chamber 42 can be adopted as follows: Figure 3 The structure shown. See also Figure 3 The bottom of the air supply chamber 42 is equipped with a drain outlet, which is connected to the water collection tank 22.

[0067] When the associated gas enters the air delivery chamber 42 from the condensing unit 3, a small amount of residual water vapor in the associated gas will condense into liquid water on the inner wall of the air delivery chamber 42. If this condensate is not drained in time, it will gradually accumulate at the bottom of the air delivery chamber 42, and may even enter the cooling pipe 41 with the associated gas. The drain outlet at the bottom of the air delivery chamber 42 is connected to the water collection tank 22. The condensed liquid water flows naturally into the drain outlet under gravity, and then is introduced into the water collection tank 22 through the sealed pipe 43, where it is collected together with the condensate discharged from the condensing unit 3, preventing it from stagnating in the air delivery chamber 42.

[0068] In this embodiment, a pressure valve can be installed at the bottom of the gas delivery chamber 42. After the liquid level in the gas delivery chamber 42 reaches a certain height, the pressure valve will automatically drain water into the water collection tank 22 to ensure that the gas delivery chamber 42 always maintains a liquid seal and prevents associated gas from flowing out.

[0069] In some embodiments, the cooling pipe 41 may be as follows: Figure 9 The structure shown. See also Figure 9Each cooling pipe 41 is provided with multiple condenser sleeves 45 at intervals. Each condenser sleeve 45 has a conical structure, with the smaller diameter end facing the outlet direction of the cooling pipe 41. Multiple water-cutting holes 46 are evenly distributed on the side wall of each condenser sleeve 45.

[0070] Under high pressure (0.2-0.5MPa), the associated gas impacts the wall of the cooling pipe 41 at a flow rate of >8m / s, directly destroying the laminar boundary layer, reducing the gas resistance by more than 40%, and further improving the condensation effect, thus preventing the associated gas from stagnating in the cooling pipe 41.

[0071] The associated gas enters the cooling pipe 41 under the control of the gas guide valve seat 5 and flows along the axis of the cooling pipe 41 towards the outlet. When the associated gas flows through the conical condenser jacket 45, because the condenser jacket 45 has a conical structure and the small diameter end faces the outlet, the airflow is guided by the condenser jacket 45 to the pipe wall of the cooling pipe 41 (the airflow diffuses to the pipe wall through the inclined surface of the side wall of the cone), increasing the contact area between the associated gas and the low temperature pipe wall. At the same time, the condenser jacket 45 itself is affected by the low temperature of the cooling pipe 41, and the surface temperature is low. The residual water vapor in the associated gas will condense into liquid water on the surface of the condenser jacket 45. Under the action of gravity, this condensate can flow out through the water interception hole 46, and finally be introduced into the water collection tank 22 through the subsequent pipeline (the discharge port can be set on the side wall at the outlet of the cooling pipe 41), while the associated gas that has undergone enhanced condensation continues to flow towards the outlet of the cooling pipe 41 and enters the exhaust pipe.

[0072] The diffusion-guiding effect of the conical condenser jacket 45 allows the associated gas to fully contact the pipe wall without prolonged flow within the cooling pipe 41, shortening the residence time of the associated gas within the cooling pipe 41. The spaced arrangement of multiple condenser jackets 45 forms a multi-stage enhanced condensation system, enabling efficient condensation within a shorter pipe length. Furthermore, condensate on the surface of the condenser jacket 45 can be quickly discharged through the water-cutting holes 46, preventing the formation of a continuous liquid film on the pipe wall that obstructs airflow, ensuring a stable associated gas flow rate, reducing detection delays caused by airflow obstruction, and significantly shortening the secondary cooling time of the associated gas, directly improving the overall detection speed. In addition, the diffusion effect of the condenser jacket 45 ensures more sufficient contact between residual water vapor in the associated gas and the low-temperature surface, preventing uncondensed water vapor in certain areas, reducing the total amount of moisture entering the drying device 23, and significantly improving detection accuracy.

[0073] In some embodiments, the aforementioned air valve seat 5 may be adopted as follows: Figure 6 and Figure 8 The structure shown. See also Figure 6 and Figure 8 The air valve seat 5 includes a seat body, a rotary disc 52, a piston, and a driver.

[0074] The base has a central cavity, and multiple sealing cylinders 51 are arranged around the central cavity. Each sealing cylinder 51 is connected to the central cavity. Each sealing cylinder 51 corresponds one-to-one with a cooling pipe 41. The end of each sealing cylinder 51 away from the central cavity is connected to an airflow chamber 54, and each airflow chamber 54 is located in the base. Each airflow chamber 54 has a one-way air inlet and a one-way air outlet. The one-way air inlet is connected to the air supply chamber 42, and the one-way air outlet is connected to the inlet of the corresponding cooling pipe 41 through a guide pipe. A turntable 52 is rotatably arranged in the central cavity. A fixed shaft is provided on the turntable 52, and the fixed shaft is arranged parallel to and spaced apart from the axis of the turntable 52. Multiple pistons are provided, and each piston is slidably arranged in each sealing cylinder 51. Each piston is connected to the fixed shaft through a hinged connecting rod 53. The driver is arranged on the base and is poweredly connected to the turntable 52.

[0075] The working principle of the air guide valve seat 5 is as follows:

[0076] After the driver is started, it drives the turntable 52 to rotate around its own axis. Since the fixed shaft is parallel to and spaced from the axis of the turntable 52, the rotation of the turntable 52 will drive the fixed shaft to make an eccentric circular motion. The fixed shaft pulls or pushes the piston in the sealing cylinder 51 through the connecting rod 53, so that the piston makes a reciprocating linear motion in the sealing cylinder 51.

[0077] When the piston in one of the sealed cylinders 51 moves away from the central cavity, the pressure inside the sealed cylinder 51 increases, the one-way outlet of the airflow chamber 54 opens and the one-way inlet closes, and the associated gas in the sealed cylinder 51 enters the cooling pipe 41 through the one-way outlet and the air guide pipe. At the same time, the piston in another set of symmetrical sealed cylinders 51 moves closer to the central cavity, creating negative pressure inside the sealed cylinder 51, opening the one-way inlet of the airflow chamber 54 and closing the one-way outlet, and the associated gas enters the airflow chamber 54 through the one-way inlet.

[0078] As the turntable 52 continues to rotate, the pistons in each sealed cylinder 51 alternately perform intake and exhaust actions, causing the associated gas to be continuously and alternately sent into each cooling pipe 41, forming a pulsed airflow, which disrupts the laminar flow state of the associated gas in the cooling pipe 41, and prevents the condensate from forming a liquid film or accumulating liquid on the pipe wall under low-speed laminar flow.

[0079] The drive-driven rotary table 52 and piston structure enable automatic alternating gas delivery of associated gas, eliminating the need for manual pressure adjustment and reducing operation time. The unidirectional inlet and outlet design prevents backflow, ensuring a continuous and stable delivery of associated gas without waiting time due to airflow interruptions. The pulsed airflow generated by alternating pressure significantly increases the flow velocity of associated gas within the cooling pipe 41, shortening its flow time. Simultaneously, the pulsed airflow disrupts the laminar flow boundary, preventing condensate buildup on the pipe walls from obstructing airflow and eliminating the need for downtime for cleaning accumulated liquid, further reducing detection interruption time. This improves the processing efficiency of associated gas within the cooling pipe 41, directly shortening the overall detection cycle.

[0080] After the pulsed airflow disrupts the laminar flow boundary, the contact between the associated gas and the wall of cooling pipe 41 becomes more uniform, avoiding the uneven condensation caused by the high temperature at the center of the airflow and the low temperature at the pipe wall under laminar flow conditions, thus ensuring that residual water vapor is fully condensed. At the same time, the condensate will not form a continuous liquid film on the pipe wall, avoiding the adsorption of components in the associated gas (such as heavy hydrocarbons and hydrogen sulfide) by the liquid film, ensuring that the composition of the associated gas is consistent with its original state, and improving the stability and accuracy of the detection results.

[0081] In some embodiments, the filtering unit 2 described above may employ, for example... Figure 4 The structure shown. See also Figure 4 The filter unit 2 includes a filter box and filter screens. The filter box has a filter chamber. The top of the filter box has a connection port communicating with the mounting hole 13, and the bottom has a filtrate outlet communicating with the evaporator 14. Multiple filter screens are provided, each arranged vertically at intervals in the filter chamber, and each filter screen is inclined. Any two adjacent filter screens are arranged in opposite inclination directions.

[0082] The spacing of multiple filter screens enables multi-layer synchronous filtration, eliminating the need for staged filtration and shortening geothermal pretreatment time. The inclined and reverse-arranged filter screens allow impurities to automatically roll down to lower levels, avoiding clogging caused by impurity accumulation in traditional horizontal filters. This eliminates the need for frequent shutdowns for filter cleaning, reducing downtime. The multi-layered, reverse-inclined filter screen design intercepts impurities of different particle sizes layer by layer, resulting in more thorough filtration. This prevents solid impurities from entering the evaporator 14 and being carried into the condensation unit 3 along with the associated gas, thus preventing impurities from adhering to the walls of the metal pipe 33 or cooling pipe 41 and affecting condensation efficiency. Simultaneously, impurities will not enter the subsequent drying device 23 or testing equipment, avoiding damage to instruments or interference with detection signals.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
