Description

Technical Field

[0001] The invention belongs to the technical field of hot spring gas collection and earthquake prediction, and particularly relates to a hot spring gas collection and pretreatment device. Background Art

[0002] Seismic monitoring technology, primarily consisting of geophysical and geochemical monitoring, is a core tool for studying crustal activity and predicting earthquake hazards. Before an earthquake, crustal stress accumulation can lead to microfractures in rocks and changes in pore pressure, prompting the upward migration of deep gases (such as He, Ne, H₂, O₂, N₂, CH₄, CO, CO₂, H₂S, and radon) along faults or fissures. Hot spring vents are one outlet for these deep gases, and they can also exhibit abnormal concentrations of ions (such as chloride, sulfate, sodium, potassium, calcium, magnesium, δ₁ ...

[0003] Currently, most gas sampling devices are single-tube devices that can only continuously collect gas from a single location at a time. If the hot spring surface is large, the gas composition at each location will vary slightly. The hot spring gas, after escaping, is hot and contains a lot of water vapor, which can affect gas detection.

DETAILED DESCRIPTION

[0019] This embodiment provides a hot spring gas collection and pre-processing device, such as Figure 1-Figure 3As shown, it includes several sampling heads 1, gas transmission condensation pipes 2 and annular adsorption tubes 5. Several sampling heads 1 are detachably connected to the side walls of the gas transmission condensation pipes 2. A mixing chamber 6 is provided inside the gas transmission condensation pipes 2 for mixing the gases input by each sampling head 1; a spiral condensation pipe 7 is provided above the mixing chamber 6, and condensed water is input into the condensation pipe 7 to cool and dehumidify the gas passing through the condensation pipe 7; an adsorption desiccant is provided in the adsorption pipe 5, and a gas interface is provided on both sides of the bottom of the adsorption pipe 5, and a gas interface is provided on the top of the adsorption pipe 5, one of the gas interfaces is connected to the top of the gas transmission condensation pipe 2, and the other gas interface is connected to the output pipe for outputting the treated gas.

[0020] Optionally, the hot spring gas collection device is vertically arranged, the gas transmission condensation pipe 2 is a cylinder, and several groups of docking ports 8 are provided on the outer wall of the gas transmission condensation pipe 2. Several groups of docking ports 8 are evenly arranged along the length direction of the gas transmission condensation pipe 2, and several docking ports 8 in each group are evenly arranged along the circumference of the gas transmission condensation pipe 2; several sampling heads 1 are connected to the same group of docking ports, that is, the number of sampling heads 1 is equal to the number of docking ports in one group, the top opening of the sampling head 1 is used to connect to the docking port, and the bottom of the sampling head 1 is provided with a flared collection cover 9; the lower the docking port to which the sampling head 1 is connected, the larger the sampling radius.

[0021] Further optionally, the sampling head 1 is cylindrical, and the bottom of the sampling head 1 is connected to the flared collection cover 9 via a first telescopic section 10, and the first telescopic section 10 is a flexible and retractable cylinder; when the inclination angle of the sampling head 1 is different, the first telescopic section 10 cooperates with the sampling head 1 through its own telescopic bending, so that the flared collection cover 9 always maintains a vertical hanging posture;

[0022] The top of the sampling head 1 is detachably connected to the docking port via the second telescopic section 11 . The second telescopic section 11 can be configured to be in different tilt angles in coordination with the sampling head 1 through its own telescopic bending.

[0023] The expanded collection cover 9 is a hollow cover in the shape of a truncated cone or a cone, which is small at the top and large at the bottom. When sampling, the bottom of the expanded collection cover 9 is immersed below the level of the hot spring water, so that the gas emerging from the water surface enters the gas condensation pipe 2 along the expanded collection cover 9 and the sampling head 1.

[0024] The first telescopic section 10 and the second telescopic section 11 are both conventional plastic cylinders with corrugated folds, which can be extended and retracted to change their own lengths, and can also bend to change the bending angles at both ends.

[0025] The docking port has an outwardly protruding edge, and the outer side surface of the edge is provided with an external thread. The top opening of the second telescopic section 11 is fixedly connected to a docking ring made of a rigid material with an internal thread. The docking ring and the docking port are connected by threads, and a sealing ring is used to ensure the airtightness of the docking port. The bottom opening of the second telescopic section 11 is fixedly connected to the top of the sampling head 1. The top of the flared collection cover 9 has an outwardly protruding edge, and the outer side surface of the edge is provided with an external thread. The bottom opening of the first telescopic section 10 is fixedly connected to a docking ring made of a rigid material with an internal thread. The docking ring and the flared collection cover 9 are connected by threads, and a sealing ring is used to ensure the airtightness of the top of the flared collection cover 9. The top opening of the first telescopic section 10 is fixedly connected to the bottom end of the sampling head 1.

[0026] Conventional gas sampling devices are single-tube devices that can only continuously collect gas from a single location at a time. If the hot spring surface is large, the gas composition at each location will vary slightly. The vertical gas condenser tube 2 designed in the present invention is provided with several groups of docking ports (i.e., several circles of docking ports) from top to bottom. Since the length of the sampling head 1 is fixed (although the lengths of the two telescopic sections can be changed, this primarily utilizes the flexibility of the two telescopic sections to accommodate the different tilt angles of the sampling head 1), when the sampling head 1 is connected to a higher docking port, the angle between the sampling head 1 and the gas condenser tube 2 decreases, and the circular sampling range enclosed by each flared collection hood 9 decreases. When the sampling head 1 is connected to a lower docking port, the angle between the sampling head 1 and the gas condenser tube 2 increases, and the circular sampling range enclosed by each flared collection hood 9 increases. The first telescopic section 10 ensures the vertical position of the flared collection hood 9, while the second telescopic section 11 coordinates with the changing tilt angle of the sampling head 1. Therefore, the design of multiple sampling heads 1 and gas condensing tubes 2 of the present invention can reasonably design the sampling range according to the size of the hot spring water surface, and take samples at multiple locations at the same time. The gases collected by multiple sampling heads 1 are gathered in the gas condensing tube 2, mixed in the mixing chamber 6, and can continue to mix in the process of rising along the condensing tube 7, thereby reducing the prediction error.

[0027] The expanded collection cover 9 is buckled on the water surface in a vertical posture, bearing the buoyancy, and can support the corresponding sampling head 1 to float on the water surface. A support rod can be set below the gas transmission condensation pipe 2 to support it on the bottom rock.

[0028] Optionally, a mixing chamber 6 is provided above the uppermost set of docking ports of the gas delivery condensation pipe 2. The inner diameter of the mixing chamber 6 is larger than that of the gas delivery condensation pipe 2, and the mixing chamber 6 is ellipsoidal. Gas input into the gas delivery condensation pipe 2 from each sampling head 1 enters the mixing chamber 6 tangentially, then flows along the inner wall of the mixing chamber 6, contacts and mixes with gas input from other sampling heads 1, and the mixed gas as a whole rotates and rises along the inner wall of the mixing chamber 6.

[0029] Optionally, the condenser tube 7 is a single spiral tube, which rotates and extends evenly along the length direction of the gas transmission condenser tube 2. The top and bottom ends of the condenser tube 7 pass through the side wall of the gas transmission condenser tube 2 and are then connected to the condensation water source. The top and bottom ends of the condenser tube 7 can both be connected to a chiller; a cooling interlayer is provided on the outer wall of the corresponding condenser tube 7 part of the gas transmission condenser tube 2, and condensation water is also passed into the cooling interlayer to cool the hot spring gas.

[0030] The gas in the mixing chamber 6 rises along the gas transmission condensation pipe 2. When it encounters the condensation pipe 7, it rotates and rises along the spiral condensation pipe 7 to be further mixed and cooled at the same time. The gas that rotates to the inner wall of the gas transmission condensation pipe 2 can also be cooled by the cooling interlayer, thereby improving the mixing and cooling effects.

[0031] After escaping, the hot spring gas is hot and contains a lot of water vapor. As it rises along sampling head 1, it naturally cools, and the condensed water droplets slide down the inclined sampling head 1 back into the hot spring. The gas and water vapor continue to rise along the gas condenser tube 2, where they are further cooled by condenser tube 7 and the cooling interlayer. Most of the water vapor in the gas sample is partially condensed in condenser tube 7, while a small amount continues to rise with the gas into adsorption tube 5 for further dehumidification.

[0032] During this process, a large amount of water droplets condense on the outer surface of the condenser tube 7 and the inner wall of the gas transmission condenser tube 2. These droplets naturally fall through the mixing chamber 6 and into the bottom of the gas transmission condenser tube 2. Finally, the drain at the bottom of the gas transmission condenser tube 2 can be opened periodically to drain the water. However, these droplets may be entrained by the rising gas and need to be recondensed, or they may directly enter the adsorption tube 5 with the gas, increasing the processing load of the adsorption tube 5. To address this problem, the present invention provides the following solution.

[0033] Optionally, a motor 12 is provided above the gas transmission condensation pipe 2, and the rotating shaft of the motor 12 penetrates into the top of the gas transmission condensation pipe 2 and is then connected to a rotating water remover in the gas transmission condensation pipe 2. The rotating water remover includes a first support ring 13, a second support ring 14, a third support ring 15, several vertical telescopic rods 17 and several horizontal connecting rods 18. The top end of the telescopic rod 17 is connected to the first support ring 13, and the bottom end is connected to the second support ring 14. A connecting rod 18 is connected between the second support ring 14 and the third support ring 15. The inner diameter of the second support ring 14 is smaller than the inner diameter of the third support ring 15. A circle of sponge strips 20 is provided on the outer side surface of the third support ring 15. The sponge strips 20 can contact the inner wall of the gas transmission condensation pipe 2. The motor 12 drives the sponge strip 20 to rotate, and then cooperates with the telescopic rod 17 to drive the sponge strip 20 to rise and fall, wiping and absorbing water droplets on the inner wall of the gas transmission condensation pipe 2.

[0034] Further optionally, the first support ring 13, the second support ring 14, and the third support ring 15 are all circular. The first support ring 13 and the second support ring 14 have the same inner diameter, are located in corresponding vertical positions, are concentrically arranged, and are connected by a telescopic rod 17. The second support ring 14 and the third support ring 15 are located on the same horizontal plane and are concentrically arranged. The outer diameter of the third support ring 15 is slightly smaller than the inner diameter of the gas transmission condenser tube 2, so that the sponge strip 20 can contact the inner wall of the gas transmission condenser tube 2. The inner diameters of the first support ring 13 and the second support ring 14 are larger than the outer diameter of the condenser tube 7 to prevent the telescopic rod 17 from colliding with the condenser tube 7.

[0035] Further optionally, the top ends of several telescopic rods 17 are evenly arranged along the circumference of the first support ring 13, and the bottom ends of several telescopic rods 17 are also evenly arranged along the circumference of the second support ring 14, so that the telescopic rods 17 remain vertical for easy extension and retraction; several connecting rods 18 are evenly arranged along the circumference of the second support ring 14.

[0036] The motor 12 is outside the gas transmission condensation pipe 2 and can be provided with an external protective cover to prevent moisture from affecting the motor 12. Preferably, a connecting pipe 22 is provided next to the motor 12 to connect the gas transmission condensation pipe 2 and the adsorption pipe 5.

[0037] The telescopic rods 17 are conventional telescopic rods with a telescopic mechanism. These rods 17 can be electromagnetically controlled, with a controller located on the first support ring 13. Each of the telescopic rods 17 is connected to the controller, controlling the synchronous extension and retraction of the rods 17. The rotating shaft of the motor 12 can be connected to the first support ring 13 via several rods, thereby driving the first support ring 13 to rotate. This, in turn, drives the third support ring 15 through the telescopic rods 17 and the second support ring 14 to clean the inner wall of the gas condenser tube 2. Simultaneously, the telescopic rods 17 extend and retract synchronously, driving the second and third support rings 15 to rotate while also moving them up and down, providing a more comprehensive cleaning of the inner wall of the gas condenser tube 2.

[0038] Further optionally, a circular water collecting trough is provided on the inner wall of the gas transmission condensation pipe 2, and the water collecting trough is located between the mixing bin 6 and the condensation pipe 7, and is used to collect water droplets sliding down the inner wall of the gas transmission condensation pipe 2 and excess water from the sponge strip 20; the water collecting trough is spiral, that is, the height of the water collecting trough gradually and evenly decreases along the circumference of the inner wall of the gas transmission condensation pipe 2, and the lowest point of the water collecting trough passes through the gas transmission condensation pipe 2 through the drain pipe to discharge the collected water.

[0039] Optionally, the rotating water remover also includes a fourth support ring 16 and an independent telescopic rod 19. The fourth support ring 16 and the first support ring 13 are on the same horizontal plane and are concentrically arranged. The fourth support ring 16 is connected to the first support ring 13 through several support rods; the top of the independent telescopic rod 19 is connected to the fourth support ring 16, and the bottom is slidably connected to the condenser 7 through the sponge ring 21. The outer diameter of the fourth support ring 16 is equal to the outer diameter of the condenser 7, so that the bottom of the independent telescopic rod 19 can rotate along the condenser 7.

[0040] Further optionally, the sponge ring 21 is sleeved on the outer surface of the condenser 7; a water collecting tray is provided below the bottom pipe mouth of the condenser 7 to collect excess water from the sponge ring 21, and the water collecting tray is connected to the inner wall of the gas transmission condenser pipe 2 through 1-2 support rods to fix the water collecting tray, and the water collecting tray is connected to the water collecting tank through a water pipe.

[0041] The independent telescopic rod 19 is a conventional telescopic rod, also electromagnetically controlled. A controller can be located on either the first support ring 13 or the fourth support ring 16. The independent telescopic rod 19 is connected to the controller to control its extension or contraction. The motor 12 drives the fourth support ring 16 to rotate synchronously with the first support ring 13, allowing the independent telescopic rod 19 to rotate as well. As the independent telescopic rod 19 rotates along the spiral condenser tube 7, it also extends, causing the sponge ring 21 to spiral down along (i.e., around) the condenser tube 7, wiping and absorbing water droplets from the surface of the condenser tube 7 until the sponge ring 21 reaches the lowest point of the condenser tube 7, at which point the independent telescopic rod 19 is stretched to its full length. Excess water from the sponge ring 21 falls into the water collection tray and then into the sump. The independent telescopic rod 19 then rotates in the opposite direction and contracts, leading the sponge ring 21 up along the condenser tube 7 to its highest point (also causing the sponge strip 20 to rise).

[0042] The present invention utilizes a motor 12 to simultaneously rotate a sponge strip 20 and a sponge ring 21 by simply rotating the dehumidifier. These motors 12 wipe the inner wall of the gas transmission condenser tube 2 and the outer wall of the condenser tube 7, respectively, removing condensed water droplets by absorption and removal, and ultimately draining them through a sump. The speed and direction of each telescopic rod 17 and each support ring are controllable to prevent the sponge ring 21 from rotating too quickly and becoming incompatible with the spiral shape of the condenser tube 7. Furthermore, the rotation of each telescopic rod 17 and each support ring also agitates the gas within the gas transmission condenser tube 2, enhancing mixing and cooling effects.

[0043] Optionally, the adsorption tube 5 is arranged vertically, and the top of the gas transmission condensation pipe 2 supports the adsorption tube 5 through a vertical connecting pipe 22. A plurality of disc-shaped silos 23 are provided in the adsorption tube 5, and the silos 23 are filled with conventional adsorption desiccant; the central axis in the adsorption tube 5 is circular, and a circular bracket 24 is provided along the central axis. The silos 23 are fixed on the bracket 24 and are evenly distributed along the circumference of the bracket 24. The disc surface of each silo 23 is perpendicular to the tangential direction of the bracket 24.

[0044] A partition 25 is provided at the bottom of the adsorption tube 5 . The partition 25 is provided between the two gas interfaces at the bottom of the adsorption tube 5 . The partition 25 can cover the cross section of the adsorption tube 5 and block the space between the two gas interfaces at the bottom of the adsorption tube 5 .

[0045] The center of the silo 23 lies on the central axis, leaving a minimal gap between the edges of the silo 23 and the inner wall of the adsorption tube 5. One circular surface of the silo 23 is retractable, facilitating replacement of the adsorption desiccant. The ends of the bracket 24 are fixed to the two sides of the partition 25. The remaining portions of the bracket 24 are connected to the inner wall of the adsorption tube 5 via rods to support the bracket 24. The adsorption tube 5 can be constructed by snapping together two circular shells, each with a semicircular cross-section, equivalent to a shell formed by vertically cutting the adsorption tube 5, facilitating replacement of the silo 23.

[0046] Alternatively, the connecting tube 22 is hollow, and a gas outlet pipe is connected to the side of the connecting tube 22 , which can be detachably connected to the two gas interfaces at the bottom of the adsorption tube 5 .

[0047] In a specific embodiment, the right gas interface at the bottom of the adsorption tube 5 is the first gas interface 26, the left gas interface is the second gas interface 3, and the top gas interface of the adsorption tube 5 is the third gas interface 4. A partition 25 is provided between the first gas interface 26 and the second gas interface 3, and the first gas interface 26 and the second gas interface 3 are arranged near the partition 25. The outlet pipe is connected to the first gas interface 26, the third gas interface 4 is closed, and the second gas interface 3 is connected to the output pipe. Hot spring gas enters the adsorption tube 5 from the first gas interface 26, passes through each silo 23 in a counterclockwise direction, and the desiccant absorbs moisture in the gas. Finally, the gas is output from the second gas interface 3. After a period of time, the silo 23 on the right side of the adsorption tube 5 is first saturated with adsorption. The outlet pipe is then connected to the second gas interface 3. The first gas interface 26 is closed, and the third gas interface 4 is connected to the output pipe. Hot spring gas enters the adsorption tube 5 from the second gas interface 3, passes through the silo 23 on the left side of the adsorption tube 5 in a clockwise direction, and is output from the top of the adsorption tube 5, fully utilizing the silo 23 on the left side that has not been adsorbed. When all the silos 23 are saturated with adsorption, gas extraction is stopped and the desiccant is replaced.
