Description

Technical Field

[0001] The present 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 is the core means to study crustal activities and predict earthquake disasters, mainly including geophysical monitoring and geochemical monitoring. Before an earthquake, the accumulation of crustal stress will cause micro-cracks in rocks and changes in pore pressure, prompting deep gases (such as He, Ne, H2, O2, N2, CH4, CO, CO2, H2S, radon, etc.) to migrate upward along faults or fractures. The hot spring outlet is one of the outlets for these deep gases to overflow. At the same time, the concentrations of components in the hot spring water quality (such as chloride ions, sulfate ions, sodium ions, potassium ions, calcium ions, magnesium ions, δ18O, and δD, etc.) will also show anomalies. Therefore, the hot spring outlet is a "window" of crustal activities. The abnormal fluctuations in the concentrations, isotope ratios, or release rates of deep gases and various components in groundwater can directly reflect the changes in the deep stress field, earlier than seismic waves or surface deformation signals.

[0003] Currently, most gas collection devices are single-tubular and can only continuously collect gases at a single position at the same time. If the hot spring surface is large, the gas components at each position will be slightly different. The temperature of the hot spring gas after overflow is relatively high and contains a lot of water vapor, which affects gas detection. Therefore, pretreatment of cooling and dehumidification of the hot spring gas is required. Summary of the Invention

Detailed Embodiment

[0015] This embodiment provides a hot spring gas collection and pretreatment device, as Figures 1 - 3 shown, including a plurality of sampling heads 1, a gas transmission condensation tube 2, and an annular adsorption tube 5. A plurality of sampling heads 1 are detachably connected to the side wall of the gas transmission condensation tube 2. A mixing chamber 6 is provided inside the gas transmission condensation tube 2 for mixing the gases input by each sampling head 1; a spiral condensation tube 7 is provided above the mixing chamber 6, and condensed water is input into the condensation tube 7 to cool and dehumidify the gas passing through the condensation tube 7; an adsorption desiccant is provided inside the adsorption tube 5, and a gas interface is provided on each side of the bottom of the adsorption tube 5, and a gas interface is provided at the top of the adsorption tube 5. One of the gas interfaces is connected to the top of the gas transmission condensation tube 2, and the other gas interface is connected to an output pipe for outputting the processed gas.

[0016] Optionally, the hot spring gas collection device is vertically arranged, the gas transmission and condensation pipe 2 is cylindrical, and several groups of docking ports 8 are provided on the outer side wall of the gas transmission and condensation pipe 2. The several groups of docking ports 8 are evenly arranged along the length direction of the gas transmission and condensation pipe 2, and several docking ports 8 in each group are evenly arranged along the circumferential direction of the gas transmission and 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 a group. The top opening of the sampling head 1 is used to connect the docking port, and a flared collection cover 9 is provided at the bottom of the sampling head 1; the lower the docking port connected by the sampling head 1, the larger the sampling radius.

[0017] Further optionally, the sampling head 1 is cylindrical, and the bottom of the sampling head 1 is connected to the flared collection cover 9 through a first telescopic section 10. The first telescopic section 10 is a flexible and telescopic 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 vertically suspended posture; The top of the sampling head 1 is detachably connected to the docking port through a second telescopic section 11. The second telescopic section 11 can be bent at different inclination angles by cooperating with the sampling head 1 through its own telescopic bending.

[0018] The flared collection cover 9 is a frustum-shaped or conical hollow cover, with a smaller top and a larger bottom. During sampling, the bottom of the flared collection cover 9 is immersed below the hot spring water level, so that the gas emerging from the water surface enters the gas transmission and condensation pipe 2 along the flared collection cover 9 and the sampling head 1.

[0019] Both the first telescopic section 10 and the second telescopic section 11 are conventional plastic cylinders with corrugated folds, which can stretch to change their own length and can also bend to change the bending angle at both ends of themselves.

[0020] The docking port has a protruding edge, and an external thread is provided on the outer side surface of the edge. 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 is threadedly connected to the docking port, and then a sealing ring is used to ensure the airtightness at the docking port. The bottom opening of the second telescopic section 11 is fixedly connected to the top end of the sampling head 1. The top of the flared collection cover 9 has a protruding edge, and an external thread is provided on the outer side surface of the edge. 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 is threadedly connected to the flared collection cover 9, and then a sealing ring is used to ensure the airtightness at 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.

[0021] Traditional gas collection devices are single-tubular and can only continuously collect gas at a single location at the same time. If the surface of the hot spring is large, the gas components at each location will be slightly different. The vertical gas transmission and condensation pipe 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, but mainly utilize the bendable function of the two telescopic sections to cooperate with different tilting angles of the sampling head 1), when the sampling head 1 is connected to the docking port at a higher position, the angle between the sampling head 1 and the gas transmission and condensation pipe 2 becomes smaller, and the circular sampling range enclosed by each flared collection cover 9 becomes smaller; when the sampling head 1 is connected to the docking port at a lower position, the angle between the sampling head 1 and the gas transmission and condensation pipe 2 becomes larger, and the circular sampling range enclosed by each flared collection cover 9 becomes larger. The first telescopic section 10 can ensure the vertical posture of the flared collection cover 9, and the second telescopic section 11 can cooperate with the sampling head 1 to change the tilting angle. Therefore, the design of multiple sampling heads 1 and the gas transmission and condensation pipe 2 in the present invention can reasonably design the sampling range according to the size of the hot spring water surface, and sample at multiple locations at the same time. The gases collected by multiple sampling heads 1 converge into the gas transmission and condensation pipe 2, are mixed in the mixing chamber 6, and can continue to be mixed during the process of rising along the condensation pipe 7, reducing the prediction error.

[0022] The flared collection cover 9 is buckled on the water surface in a vertical posture, bears the buoyancy, and can support the corresponding sampling head 1 to float on the water surface. A support rod can be arranged below the gas transmission and condensation pipe 2 to support on the underwater rock.

[0023] Optionally, a mixing chamber 6 is provided above the topmost group of docking ports of the gas transmission and condensation pipe 2. The inner diameter of the mixing chamber 6 is larger than the inner diameter of the gas transmission and condensation pipe 2, and the mixing chamber 6 is an ellipsoid. The gas input into the gas transmission and condensation pipe 2 from each sampling head 1 enters the mixing chamber 6 along the tangential direction, then flows along the inner wall of the mixing chamber 6, contacts and mixes with the 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.

[0024] Optionally, the condensation pipe 7 is a single spiral pipe, which extends uniformly and rotationally along the length direction of the gas transmission and condensation pipe 2. The top and bottom ends of the condensation pipe 7 both penetrate through the side wall of the gas transmission and condensation pipe 2 and then connect to the condensation water source. The top and bottom ends of the condensation pipe 7 can both be connected to a chiller; a cooling interlayer is provided on the outer side wall of the corresponding part of the gas transmission and condensation pipe 2 for the condensation pipe 7, and condensation water is also introduced into the cooling interlayer to cool the hot spring gas.

[0025] The gas in the mixing chamber 6 rises along the gas transmission and condensation pipe 2. When it encounters the condensation pipe 7, it rotates and rises along the spiral condensation pipe 7, further mixing, and at the same time cooling. The gas rotating to the inner wall of the gas transmission and condensation pipe 2 can also be cooled by the cooling interlayer, improving the mixing effect and the cooling effect.

[0026] The temperature of the hot spring gas is relatively high after overflow, and it also contains a large amount of water vapor. When the gas and water vapor rise along the sampling head 1, they will naturally cool down, and the condensed water droplets will slide back into the hot spring along the inclined sampling head 1. The gas and water vapor continue to rise along the gas transmission and condensation pipe 2, and are further cooled by the condensation pipe 7 and the cooling interlayer. Most of the water vapor in the gas sample is condensed in the condensation pipe 7, and a small part of the water vapor follows the gas and continues to rise into the adsorption pipe 5 for further dehumidification.

[0027] In the above process, a large amount of water droplets will condense on the outer side of the condensation pipe 7 and the inner wall of the gas transmission and condensation pipe 2. The water droplets will naturally fall, pass through the mixing chamber 6 and fall to the bottom of the gas transmission and condensation pipe 2. Finally, the drain port at the bottom of the gas transmission and condensation pipe 2 can be opened regularly to drain water. However, the falling water droplets may be carried away again by the rising gas, and need to be re-condensed, or directly enter the adsorption pipe 5 with the gas, increasing the processing load of the adsorption pipe 5. To solve this problem, the present invention provides the following solutions.

[0028] Optionally, a motor 12 is provided above the gas transmission and condensation pipe 2. The rotating shaft of the motor 12 penetrates into the top of the gas transmission and condensation pipe 2 and then connects to a rotating water remover inside the gas transmission and condensation pipe 2. The rotating water remover includes a first support ring 13, a second support ring 14, a third support ring 15, a plurality of vertical telescopic rods 17 and a plurality of horizontal connecting rods 18. The top ends of the telescopic rods 17 are connected to the first support ring 13, and the bottom ends are connected to the second support ring 14. Connecting rods 18 are 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 sponge strip 20 is provided on the outer side of the third support ring 15, and the sponge strip 20 can contact the inner wall of the gas transmission and condensation pipe 2. The motor 12 drives the sponge strip 20 to rotate, and together with the telescopic rods 17, drives the sponge strip 20 to lift and lower, wiping and absorbing the water droplets on the inner wall of the gas transmission and condensation pipe 2.

[0029] Further optionally, the first support ring 13, the second support ring 14, and the third support ring 15 are all circular. The inner diameters of the first support ring 13 and the second support ring 14 are the same, and they are vertically corresponding and concentrically arranged, and are connected by telescopic rods 17; the second support ring 14 and the third support ring 15 are 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 and condensation pipe 2, so that the sponge strip 20 can contact the inner wall of the gas transmission and condensation pipe 2. The inner diameters of the first support ring 13 and the second support ring 14 are larger than the outer diameter of the condensation pipe 7 to prevent the telescopic rods 17 from colliding with the condensation pipe 7.

[0030] Further optionally, the top ends of the plurality of telescopic rods 17 are uniformly arranged along the circumference of the first support ring 13, and the bottom ends of the plurality of telescopic rods 17 are also uniformly arranged along the circumference of the second support ring 14, so that the telescopic rods 17 remain vertical for easy telescoping; the plurality of connecting rods 18 are uniformly arranged along the circumference of the second support ring 14.

[0031] The motor 12 is located outside the gas transmission and condensation pipe 2, and a protective cover can be externally provided to prevent the influence of water vapor on the motor 12. Preferably, a connecting pipe 22 is provided beside the motor 12 to connect the gas transmission and condensation pipe 2 and the adsorption pipe 5.

[0032] The telescopic rod 17 is a conventional sleeve telescopic rod. The telescopic rod 17 can be electromagnetically controlled to expand and contract. The controller can be arranged on the first support ring 13, and each telescopic rod 17 is connected to the controller to control the synchronous extension or shortening of the telescopic rod 17. The rotating shaft of the motor 12 can be connected to the first support ring 13 through several rods, thereby driving the first support ring 13 to rotate. Then, through the telescopic rod 17 and the second support ring 14, the third support ring 15 is driven to rotate to wipe the inner wall of the gas transmission and condensation pipe 2. At the same time, the telescopic rod 17 expands and contracts synchronously, driving the second and third support rings 15 to rotate and move up and down at the same time, more comprehensively cleaning the inner wall of the gas transmission and condensation pipe 2.

[0033] Further optionally, a circular water collecting groove is provided on the inner wall of the gas transmission and condensation pipe 2. The water collecting groove is located between the mixing chamber 6 and the condensation pipe 7, and is used to collect the water droplets sliding down on the inner wall of the gas transmission and condensation pipe 2 and the excess water of the sponge strip 20; the water collecting groove is spiral, that is, the height of the water collecting groove gradually decreases uniformly along the circumferential direction of the inner wall of the gas transmission and condensation pipe 2. The lowest part of the water collecting groove passes through the gas transmission and condensation pipe 2 through a drain pipe to discharge the collected water.

[0034] Optionally, the rotating water remover further includes a fourth support ring 16 and an independent telescopic rod 19. The fourth support ring 16 is on the same horizontal plane as the first support ring 13 and is 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 condensation pipe 7 through a sponge ring 21. The outer diameter of the fourth support ring 16 is equal to the outer diameter of the condensation pipe 7, so that the bottom of the independent telescopic rod 19 can rotate along the condensation pipe 7.

[0035] Further optionally, the sponge ring 21 is sleeved on the outer side surface of the condensation pipe 7; a water collecting tray is provided below the bottommost pipe orifice of the condensation pipe 7 to receive the excess water of the sponge ring 21. The water collecting tray is connected to the inner wall of the gas transmission and condensation pipe 2 through 1-2 support rods to fix the water collecting tray, and the water collecting tray is connected to the water collecting groove through a water pipe.

[0036] The independent telescopic rod 19 is a conventional sleeve telescopic rod, and the independent telescopic rod 19 is also telescopically controlled electromagnetically. The controller can be arranged on the first support ring 13 or the fourth support ring 16. The independent telescopic rod 19 is connected to the controller to control the elongation or shortening of the independent telescopic rod 19. The motor 12 drives the fourth support ring 16 and the first support ring 13 to rotate synchronously. The independent telescopic rod 19 can also rotate. When the independent telescopic rod 19 rotates along the spiral condenser tube 7, it also elongates, causing the sponge ring 21 to spiral down along the condenser tube 7 (i.e., around the condenser tube 7) to wipe and absorb the water droplets on the surface of the condenser tube 7 until the sponge ring 21 moves to the lowest end of the condenser tube 7. At this time, the independent telescopic rod 19 is fully extended to the longest. The excess water of the sponge ring 21 falls into the water collecting tray and then flows into the water collecting tank. Then, the independent telescopic rod 19 rotates in the reverse direction and shortens, leading the sponge ring 21 to rise along the condenser tube 7 to the highest point of the condenser tube 7 (simultaneously driving the sponge strip 20 to rise as well).

[0037] In the present invention, by simply rotating the water remover, with a single motor 12, the sponge strip 20 and the sponge ring 21 are simultaneously driven to rotate, respectively wiping the inner wall of the gas transmission condenser tube 2 and the outer wall of the condenser tube 7, adsorbing and carrying away the condensed water droplets, and finally discharging them through the water collecting tank. The rotation speed and direction of each telescopic rod 17 and each support ring can be controlled to prevent the sponge ring 21 from rotating too fast and not adapting to the spiral shape of the condenser tube 7. At the same time, the rotation of each telescopic rod 17 and each support ring can also stir the gas in the gas transmission condenser tube 2, improving the mixing effect and the cooling effect.

[0038] Optionally, the adsorption tube 5 is arranged vertically. The top of the gas transmission condenser tube 2 supports the adsorption tube 5 through a vertical connecting tube 22. A plurality of disc-shaped bins 23 are arranged in the adsorption tube 5, and conventional adsorption desiccants are filled in the bins 23. The central axis in the adsorption tube 5 is circular, and a circular support 24 is arranged along this central axis. The bins 23 are fixed on the support 24 and are evenly distributed along the circumference of the support 24. The disc surface of each bin 23 is perpendicular to the tangential direction of the support 24 where it is located; A partition 25 is arranged at the bottom of the adsorption tube 5. The partition 25 is arranged 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.

[0039] The center of the bin 23 is on the central axis. There is a very small gap between the edge side surface of the bin 23 and the inner wall of the adsorption tube 5. One circular surface of the bin 23 is openable and closable for easy replacement of the adsorption desiccant. The two ends of the support 24 are respectively fixed on the two side surfaces of the partition 25, and other positions of the support 24 are connected to the inner wall of the adsorption tube 5 through rods to support the support 24. The adsorption tube 5 can be formed by buckling two circular shells, and the cross-section of each shell is semi-circular, which is equivalent to the shell obtained by cutting the adsorption tube 5 vertically in the vertical direction, facilitating the replacement of the bin 23.

[0040] Further optionally, the inside of the connecting pipe 22 is hollow, and an air outlet pipe is connected to the side surface of the connecting pipe 22. The air outlet pipe can be detachably connected to two gas interfaces at the bottom of the adsorption pipe 5. The inside of the connecting pipe 22 is not communicated with the internal space of the adsorption pipe 5.

[0041] As a specific implementation manner, the gas interface on the right side at the bottom of the adsorption pipe 5 is the first gas interface 26, the gas interface on the left side is the second gas interface 3, and the gas interface at the top of the adsorption pipe 5 is the third gas interface 4. A partition plate 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 close to the partition plate 25. The air 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. The hot spring gas is input into the adsorption pipe 5 from the first gas interface 26, passes through each bin 23 in the counterclockwise direction, the desiccant absorbs the moisture in the gas, and finally the gas is output from the second gas interface 3. After allowing for a period of time, the bin 23 on the right side of the adsorption pipe 5 is first saturated with adsorption. The air outlet pipe is changed to be 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. The hot spring gas is input into the adsorption pipe 5 from the second gas interface 3, passes through the bin 23 on the left side of the adsorption pipe 5 in the clockwise direction, and then is output from the top of the adsorption pipe 5, making full use of the bin 23 on the left side that has not been adsorbed. When all the bins 23 are saturated with adsorption, the gas extraction is stopped and the desiccant is replaced.
