Description

Technical Field

[0001] The utility model relates to the technical field of gas sample taking devices, and more specifically, to a device for taking gas samples from ice bubbles. Background Art

[0002] Methane is produced from sediments at the bottom of water bodies. There are often a large amount of organic substances in the sediments. Due to the special environment at the bottom of the water body, many anaerobic microorganisms live here. While utilizing organic substances, anaerobic microorganisms will decompose them into small molecule methane and finally release methane gas into the water. Methane is not soluble in water, and they will form bubbles and finally be released into the atmosphere. The efficiency of the decomposition of these microorganisms is related to temperature. Research shows that if the global temperature rises by 1°C, the emission of methane bubbles will increase by 20%. Methane is an important greenhouse gas, which can stay in the atmosphere for a long time, and the greenhouse effect it causes is more than 20 times that of carbon dioxide. Excessive methane discharged from water bodies will lead to an accelerated rise in the earth's temperature, and the accelerated warming will trigger more methane releases, forming a vicious cycle. Freshwater lakes like this are high-value areas for methane gas emissions. Therefore, in winter, when the lake surface is frozen, the discharged methane will be embedded in the ice layer to form "bubble ice". Although this scenery is special, it is very dangerous for global warming.

[0003] In order to study global warming, obtaining the methane release amount has become an important indicator. The content of methane release can be directly extracted from bubble ice, but currently, there is no device for directly extracting gas samples from bubble ice. Summary of the Utility Model

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the drawings.

[0027] Specific implementation plan one: As shown in combination with Figures 1 to 4 The present utility model provides a device for collecting gas samples from ice bubbles, including a base 12, a water injection bottle 1, a heating base 3, a water injection pipe 5, an ice bubble placement bottle 8, and a balloon 9. The water injection bottle 1 and the ice bubble placement bottle 8 are both arranged on the base 12, and the bottom of the water injection bottle 1 is higher than the top of the ice bubble placement bottle 8, so that the water 2 in the water injection bottle 1 can flow into the ice bubble placement bottle 8; A heating base 3 is provided under the water injection bottle 1 to heat the water 2 in the water injection bottle 1, facilitating the melting of the ice bubble sample 10 and the release of the gas sample in the ice bubble sample 10; The water injection bottle 1 is communicated with the ice bubble placement bottle 8 through the water injection pipe 5, and a valve 6 is arranged on the water injection pipe 5 to inject the heated water 2 in the water injection bottle 1 into the ice bubble placement bottle 8 by controlling the valve 6; The ice bubble placement bottle 8 is used to place the ice bubble sample 10, and a balloon 9 is sleeved at the upper opening of the ice bubble placement bottle 8 to collect the gas sample discharged from the ice bubble sample 10 through the balloon 9.

[0028] Specific Embodiment 2: Different from Specific Embodiment 1, both ends of the water injection pipe 5 are respectively communicated with the side wall near the bottom of the water injection bottle 1 and the side wall near the bottom of the ice bubble placement bottle 8, which is convenient for exhausting the water 2 in the water injection bottle 1 as much as possible. At the same time, it is convenient for the heated water 2 to fully contact the ice bubble sample 10, and it does not affect filling the ice bubble placement bottle 8 with water 2 and squeezing all the gas samples in the ice bubble placement bottle 8 into the balloon 9.

[0029] Specific Embodiment 3: Different from Specific Embodiment 2, the opening size of the ice bubble placement bottle 8 is larger than the size of the ice bubble sample 10, which is used to put the ice bubble sample 10 into the ice bubble placement bottle 8 from the opening. Or the bottom of the ice bubble placement bottle 8 is hollowed out, and an external thread 801 is provided outside the side wall near the bottom of the ice bubble placement bottle 8. The ice bubble placement bottle 8 is connected to the base 12 by a thread, that is, the ice bubble placement bottle 8 is embedded into the base 12. During use, the ice bubble placement bottle 8 can be unscrewed, then the ice bubble sample 10 can be placed, and then the ice bubble placement bottle 8 can be installed back on the base 12. In this way, the opening size of the ice bubble placement bottle 8 does not need to be limited, but the installation part needs to be sealed to prevent air leakage or water leakage.

[0030] Specific Embodiment 4: Different from Specific Embodiment 3, it further includes a heightening plate 4 and a connecting rod 11. The heightening plate 4 is connected to the base 12 by the connecting rod 11, and the heating base 3 is placed on the heightening plate 4. By setting the heightening plate 4 and the connecting rod 11, it is more convenient to operate and there is no need to prepare additional heightening objects to pad up the water injection bottle 1.

[0031] The heating base 3 can control the heating temperature, which is convenient for adjusting the water temperature, avoiding the water temperature being too high to affect the gas sample collection of the ice bubble sample 10, or the temperature being too low to affect the melting speed of the ice bubble sample 10.

[0032] The water injection bottle 1 is a high-temperature resistant water injection bottle, and the ice bubble placement bottle 8 is a high-temperature and low-temperature resistant ice bubble placement bottle, which is used to prevent the water injection bottle 1 and the ice bubble placement bottle 8 from being damaged due to too high temperature, and to prevent the ice bubble placement bottle 8 from being damaged due to too low temperature. The water injection pipe 5 is a high-temperature resistant water injection pipe, which is used to prevent the water injection pipe 5 from being damaged due to too high water temperature.

[0033] The top of the water injection bottle 1 is provided with a bottle mouth and a bottle stopper, which is used to inject water 2 through the bottle mouth, and the bottle stopper can be plugged when not in use to prevent content pollution.

[0034] The capacity of the water injection bottle 1 is larger than the capacity of the ice bubble placement bottle 8, which is convenient for filling the ice bubble placement bottle 8 and squeezing the gas sample out of the ice bubble placement bottle 8.

[0035] A fixing rope is tied at the bottle mouth of the ice bubble placement bottle 8 sleeved with the balloon 9, which plays a role in further fixing the balloon 9 and preventing gas sample leakage.

[0036] Operation process:

[0037] Place the ice bubble sample 10 in the ice bubble placement bottle 8. A balloon 9 is sleeved at the opening of the ice bubble placement bottle 8 and fixed with a fixing rope. At this time, the balloon 9 is not inflated. Inject water 2 with a volume greater than that of the ice bubble placement bottle 8 into the water injection bottle 1. At this time, the valve 6 is in a closed state. Turn on the heating base 3 to heat the water 2 in the water injection bottle 1, heat the water to about 60 °C, open the valve 6, and let the hot water be injected into the ice bubble placement bottle 8 through the water injection pipe 5 until the hot water submerges the top of the position where the water injection pipe 5 communicates with the ice bubble placement bottle 8, preferably submerging the top of the ice bubble sample 10 when no hot water is injected. This is because the ice bubbles will float and it may be difficult to submerge the top of the ice bubble sample 10. Close the valve 6. After the ice bubble sample 10 is completely melted, open the valve 6 again and continue to inject water into the ice bubble placement bottle 8 through the water injection pipe 5 until it reaches the bottle mouth of the ice bubble placement bottle 8. At this time, the balloon 9 is filled with the air in the original ice bubble placement bottle 8 and the gas sample in the ice bubble sample 10. Tie the mouth of the balloon 9 and then detach it from the bottle mouth of the ice bubble placement bottle 8. The obtained gas sample can be calculated and measured according to the experimental requirements. Or first fill the ice bubble placement bottle 8 with other single gases heavier than air and non-reactive with the gas sample until it reaches the bottle mouth of the ice bubble placement bottle 8, which can discharge the air in the original bottle and avoid affecting the sample collection. Then put on the balloon 9 and perform subsequent operations. This can facilitate the subsequent calculation of the methane content.
