Description

Technical Field

[0001] This utility model belongs to the field of hot spring gas collection technology, specifically to an automatic collection device for associated gases in hot springs. Background Technology

[0002] Associated gases in hot springs refer to gases dissolved in the hot spring water that are released when the water emerges from the ground. These gases typically include nitrogen, oxygen, carbon dioxide, argon, helium, and small amounts of methane and hydrogen. Helium, as a crucial strategic material for national security and the development of high-tech industries, plays an irreplaceable role in high-tech fields such as low-temperature superconductivity, nuclear industry, and aerospace due to its unique physical properties. However, as a renewable and scarce resource, global helium consumption has increased significantly in recent years due to the rapid development of high technology.

[0003] Due to limitations such as the low yield of high-value gases like helium associated with hot springs, the complexity of existing helium extraction processes, the large size of equipment requiring specific sites, high energy consumption, high costs, and weak profitability, existing hot spring associated gas collection devices mainly serve the sampling and analysis needs of associated hot spring gases. For example, patent publication number CN210293823U discloses a spring gas sampling device, and patent publication number CN118603204A discloses hot spring escaping gas collection and analysis equipment and monitoring system. The above equipment can only be manually monitored on-site for small-scale sampling and analysis. Currently, there is no low-cost, automated collection process and equipment specifically for hot spring associated gas resources. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automatic hot spring associated gas collection device. Hot spring water is introduced into an aeration device for aeration. The released gas is condensed into water by a condenser and then separated into gas and liquid by a gas-liquid separator. The resulting gas enters a gas storage bag for buffering. When the gas storage bag stores a certain amount of gas, its length extends until it touches the weighing platform below, automatically activating the gas compressor. The gas compressor pumps the gas from the storage bag into a high-pressure gas cylinder for collection. A controller automates the control of the first and second solenoid valves and the gas compressor, enabling automatic collection of hot spring associated gases.

[0025] The following is combined with Figure 1 and Figure 2 This utility model will be described in detail.

[0026] Example

[0027] An automatic gas collection device for hot springs, such as Figure 1 As shown, the device includes an aeration device for extracting gas from a hot spring. A condenser 7 is connected to the top of the aeration device via a pipe. The condenser 7 is connected to a gas-liquid separator 8 via a pipe. A gas storage bag 10 is connected to the top of the gas-liquid separator 8 via a pipe. The upper end of the gas storage bag 10 is fixed. A weighing platform 11 is placed below the gas storage bag 10. A gas compressor 12 is connected to the top of the gas storage bag 10 via a pipe. A high-pressure gas cylinder 13 is connected to the gas compressor 12 via a pipe. A first solenoid valve 17 is installed in the pipe between the gas-liquid separator 8 and the gas storage bag 10. A second solenoid valve 18 is installed in the pipe between the gas storage bag 10 and the gas compressor 12. A controller (not shown in the figure) is connected to the first solenoid valve 17, the second solenoid valve 18, the weighing platform 11, and the gas compressor 12.

[0028] The hot spring water is introduced into an aeration device for aeration. The precipitated gas is condensed into water by a condenser 7 and then separated into gas and liquid by a gas-liquid separator 8. The resulting gas enters a gas storage bag 10 for buffering. Once the gas storage bag 10 has stored a certain amount of gas, it is then pumped into a high-pressure gas storage cylinder 13 by a gas compressor pump 12 for collection. When the gas storage bag 10 is buffering gas, the second solenoid valve 18 is closed and the first solenoid valve 17 is opened. The gas storage bag 10 gradually expands and compresses the weighing platform 11. After the weighing platform 11 senses the set value, it transmits a signal to the controller. The controller controls the first solenoid valve 17 to close and the gas compressor pump 12 and the second solenoid valve 18 to open, thereby pumping the gas in the gas storage bag 10 into the high-pressure gas storage cylinder 13 for storage. After the gas in the gas storage bag 10 is evacuated, the first solenoid valve 17, the second solenoid valve 18, and the gas compressor 12 can be opened via the controller. When the high-pressure gas storage cylinder 13 reaches a certain pressure, it can be temporarily stored near the hot spring and periodically transported to a high-value gas separation and purification base for gas separation and purification, thereby minimizing collection costs and realizing the effective development and utilization of high-value gases in associated gas from hot springs. The controller can be a PLC controller, which is existing technology and will not be described in detail here.

[0029] like Figure 2 As shown, the gas storage bag 10 is a spiral telescopic gas storage bag, and two stress induction coils 21 connected to the controller are arranged opposite each other on the upper outer side of the gas storage bag 10. In order to further realize the automatic opening of the first solenoid valve 17 and the automatic closing of the second solenoid valve 18 and the gas compressor 12, two sets of stress induction coils 21 are set. After the gas in the gas storage bag 10 is evacuated, the gas storage bag 10 will contract and cause the two sets of stress induction coils 21 to stick together. After the two sets of stress induction coils 21 stick together, they transmit the signal to the controller, and then the controller controls the first solenoid valve 17, the second solenoid valve 18 and the gas compressor 12.

[0030] The spiral telescopic gas storage bag uses a biogas storage bag with an internal spiral steel wire. The spiral telescopic gas storage bag is fixed by suspension to maintain a slight negative pressure inside, which is conducive to the collection of gas in the gas circuit.

[0031] The aeration device includes an outer shell 1, a hollow column 2 inside the outer shell 1, an inlet pipe 4 connected to the hollow column 2, several nozzles 3 arranged in a ring on the hollow column 2, and a first drain pipe 5 connected to the outer shell 1.

[0032] The nozzle 3 is set at a height that is appropriate for the pressure of the hot spring well outlet to maximize the natural energy of the spring water. The hollow column 2 is made of materials with good thermal conductivity, strength and corrosion resistance, such as stainless steel or aluminum. The outer shell 1 is made of an alloy material with high strength, certain corrosion resistance and low thermal conductivity, and is wrapped with heat insulation materials such as aerogel to minimize the decrease in hot spring temperature caused by internal aeration. For non-thermal energy utilization spring water, heat loss can be disregarded.

[0033] Spring water enters the hollow column 2 through the inlet pipe 4 and then sprays out from the nozzle 3 at the top. The water is fully aerated after falling from a height of 2-3 meters. The water sprays from multiple nozzles 3, ensuring that the aerated spring water falls from the hollow column 2 at a low flow rate and multiple angles, reducing interference between fluids. When the hot spring pressure is high, multiple layers of staggered nozzles 3 can be used to ensure the need for low flow rate and multi-angle drop. Both the inlet pipe 4 and the first drain pipe 5 are equipped with a first valve 15. The first valve 15 can be used to control the opening and closing of the inlet pipe 4 and the first drain pipe 5 as needed.

[0034] A third solenoid valve 19, connected to a controller, is installed in the pipeline between the gas compressor 12 and the high-pressure gas cylinder 13. The third solenoid valve 19 can be opened and closed as needed. For example, when it is necessary to replace the high-pressure gas cylinder 13 with a full one, the third solenoid valve 19 is closed by the controller.

[0035] A second drain pipe 14 is installed at the bottom of the gas-liquid separator 8, and a fourth solenoid valve 20 connected to the controller is installed in the second drain pipe 14. By controlling the opening and closing of the fourth solenoid valve 20, the condensate in the gas-liquid separator 8 can be discharged. A pressure gauge 9 connected to the controller is installed in the second drain pipe 14. The pressure gauge 9 monitors the pressure at the bottom of the gas-liquid separator 8. When the pressure at the bottom of the gas-liquid separator 8 exceeds the set value of the pressure gauge 9, the controller opens the fourth solenoid valve 20 to drain the water. When the bottom pressure approaches the lower pressure limit set by the pressure gauge 9, the controller closes the fourth solenoid valve 20, thereby achieving precise control of gas-liquid separation, preventing excessive residual condensate from clogging the gas-liquid mixing inlet, and preventing the bottom condensate from being released and the mixing of external air.

[0036] The condenser 7 is a condenser tube, which is made of spiral-shaped aluminum or stainless steel, or other materials with good thermal conductivity, strength, and corrosion resistance. It can cool the gas inside the tube using the low temperature of air or a low-temperature medium such as river water. When the spring water temperature is high, the length of the condenser tube can be increased to achieve sufficient condensation of water vapor in the associated gas.

[0037] A check valve 6 is installed in the pipeline between the aeration device and the condensation device 7. The check valve 6 is a buoyancy valve, which is ellipsoidal in shape. The lower part of the valve body contains a buoyancy block with a density less than water. There is a large gap between the bottom of the buoyancy block and the wall of the buoyancy valve to ensure smooth gas flow. The upper part of the buoyancy valve is a conical plug, which is fixed to the buoyancy block by a connecting rod to form a valve core. Under the buoyancy of the water, the buoyancy block can lift the conical plug to block the upper pipeline outlet to prevent spring water in the aeration device from entering the gas path.

[0038] The pipes connected to both ends of the condenser 7 are equipped with second valves 16 to facilitate repair or replacement of the condenser tubes after blockage by chlorine or corrosion by acidic gases such as H2S and SO2. The two ends of the condenser tubes are connected to the aeration device and gas-liquid separator 8 via high-temperature resistant connectors, making disassembly of the condenser tubes easier.

[0039] This application enables low-cost, automated collection of associated gas from hot springs, which not only helps in the development and utilization of associated helium from hot springs and alleviates the shortage of resources such as helium in my country, but also helps in obtaining the composition of associated gas from hot springs over a long period of time, compensating for data fluctuations caused by short-term sampling.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
