Description

Technical Field

[0001] The utility model relates to the technical field of glaciology, in particular to an ice core water isotope continuous extraction and measurement device. Background Art

[0002] In the field of polar research, glacier-related issues have always been at the forefront and hotspot of research. For millions of years, by studying glaciers, we can learn important climate information that has been preserved in the past, such as dust, suspended particles and soluble chemicals in the atmosphere. At the same time, we can also understand the history of global climate change, climate events and climate and environmental changes caused by human activities. Ice cores refer to cylindrical ice bodies drilled at snow and ice settlement sites with a certain thickness. Because the data they record has the advantages of high fidelity, large amount of information and long time series, they play an important role in restoring past climate change processes of different scales.

[0003] In fact, ice core records are further analyzed by taking indicator data (such as stable isotopes, ions, impurities, etc.) in ice cores as references. Studies have shown that stable isotope records in ice cores can be used as a reference for past climate change, mainly reflecting the continuous changes in past climate, and establishing a complete time series. Climate oscillations on long time scales can be clearly identified from the isotope records of ice cores, indirectly indicating changes in atmospheric circulation.

[0004] However, in order to study weather systems on smaller time scales in past climate change, more and more accurate data are needed. Ice core sample extraction technology is a key step in the ice core data acquisition process, which directly determines the accuracy and reliability of subsequent ice core analysis.

[0005] Traditional ice core sample preparation and testing technology is usually divided into four steps: first, remove the external ice core that is contaminated during the drilling process; second, cut the ice core into equal parts in a clean room; third, melt the sample ice core; fourth, select the corresponding testing equipment for testing and analysis. However, the above process still has the following defects: Since the ice core sample preparation process is relatively scattered (scattered: the ice core preparation process has a low degree of continuity), not all processes are integrated into one preparation line, which not only makes it easy for the ice core sample to be contaminated, but also affects the subsequent test data in the ice core sample, resulting in low accuracy of the detected ice core data.

[0006] Therefore, it is necessary to optimize and design the methods used for ice core water isotope extraction and measurement to solve the problems of low sustainability, low accuracy and easy contamination in the existing ice core water isotope extraction and measurement process.

DETAILED DESCRIPTION

[0033] like Figure 1-7 In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0034] See also Figure 1 , an ice core water isotope continuous extraction and measurement device, used for extracting and measuring isotopes in ice core water, comprising an ice core melting component 1, a debubbling component 2, an ice core water atomization and heating component 3, and an ice core water isotope measurement component 4; wherein the ice core melting component 1 is used to melt the solid ice core into liquid ice core water; the debubbling component 2 is connected to the ice core melting component 1, and is used to debubble the liquid ice core water introduced into the debubbling component 2; the ice core water atomization and heating component 3 is connected to the debubbling component 2, and is used to atomize and heat the ice core water introduced into the ice core water atomization and heating component 3 and from which bubbles have been removed; the ice core water isotope measurement component 4 is connected to the ice core water atomization and heating component 3, and is used to extract and measure the isotopes in the ice core water introduced into the ice core water isotope measurement component 4.

[0035] During the working process, when the isotopes in the ice core are extracted and measured, the solid ice core is placed in the ice core melting component 1, and the ice core melting component 1 converts the solid ice core into liquid ice core water, which is then discharged into the debubbling component 2 to debubble the liquid ice core water containing bubbles, and then discharged into the ice core water atomization and heating component 3, where the liquid ice core water is first atomized and then heated to become gas, and then discharged into the ice core water isotope measurement component 4, where the ice core water isotope measurement component 4 extracts and measures the isotopes of the gas evolved from the solid ice core, thereby completing the continuous extraction and measurement process of the isotopes in the ice core water.

[0036] See also Figure 1 , Figure 2 , Figure 6 , Figure 4 and Figure 3 The ice core melting component 1 for melting the solid ice core includes a sample placement tube 5, a melting head 6 and a heating plate 7; wherein the sample placement tube 5 is used to place the solid ice core; the melting head 6, firstly, melts the ice core placed in the sample placement tube 5 by means of heat radiation to make it into liquid ice core water; secondly, it is connected to the sample placement tube 5 to support the sample placement tube 5; the heating plate 7, by means of heat conduction, transfers its own heat to the melting head 6, so that the melting head 6 has a certain temperature, so that the solid ice core is melted in a short time.

[0037] Specifically, the open end at the bottom of the sample placement tube 5 is threadedly connected to the liquid inlet end of the melting head 6, the liquid guide section of the melting head 6 is threadedly connected to the middle of the heating plate 7, and the liquid outlet end of the melting head 6 is connected to the liquid inlet end of the first diversion branch 8

[0038] In actual use, during the melting of the solid ice core, the heating plate 7 is first heated, and the heated heating plate 7 then uses its own heat to heat the melting head 6 disposed in the middle of the heating plate 7 by heat conduction. The heated melting head 6 then heats the ice core in the sample placement tube 5 by heat radiation, so that the solid ice core is melted into liquid ice core water, which is then discharged from the liquid outlet of the melting head 6 into the first diversion branch 8. Among them, there are inevitably bubbles in the liquid ice core water melted by the melting head 6. In order to remove the bubbles therein, the liquid outlet of the first diversion branch 8 is connected to the liquid inlet end of the defoaming component 2.

[0039] See also Figure 2 , Figure 6 , Figure 5 , Figure 4 and Figure 3 The heating plate 7 for conducting heat to the melting head 6 includes a heating plate body 9, a hot water inlet interface 10 and a warm water outlet interface 11; wherein the heating plate body 9, as a heat source, is used to conduct its own heat to the melting head 6, so that the melting head 6 as a whole has a certain temperature to melt the solid ice core; the hot water inlet interface 10 is used to introduce high-temperature hot water into the heating plate body 9, so that the heating plate body 9 has a certain temperature; the warm water outlet interface 11 is used to outlet the warm water whose inner cavity temperature of the heating plate body 9 is not enough to heat the heating plate body 9.

[0040] Specifically, the heating disc 9 is a cavity structure with a threaded heat-conducting groove 13 in the middle, and the side walls of the heating disc 9 are respectively provided with a hot water inlet interface 10 and a warm water outlet interface 11, which are respectively connected to the cavity inside the heating disc 9. The hot water inlet interface 10 and the warm water outlet interface 11 are both provided with corresponding valves to introduce hot water into the heating disc 8 or to outlet the warm water in the heating disc 8.

[0041] In actual use, during the heat conduction process of the heating disc 7 to the melting head 6, the valve 1 of the warm water outlet interface 11 is first closed, and then the pipe connected to the boiler hot water outlet is connected to the hot water inlet interface 10, and then the valve 2 on the hot water inlet interface 10 is opened to allow the high-temperature boiler water to enter the inner cavity of the heating disc body 9 to heat the heating disc 7, and then the heat of the heating disc 7 is transferred to the melting head 6 by heat conduction to heat it up. The heated melting head 6 acts on the ice core in the form of thermal radiation to melt the ice core; after using it for a period of time, if the water temperature in the heating disc body 9 is too low, the valve 2 on the hot water inlet interface 10 is closed, and the valve 1 of the warm water outlet interface 11 is opened to discharge the water in the heating disc body 9 to ensure that the temperature of the heating disc 7 is too high and the melting head 6 is better heat-conducted.

[0042] It should be noted that in order to prevent the ice core water flowing into the liquid guide section of the melting head 6 from freezing due to the decrease in temperature and to facilitate disassembly, the threaded heat conduction groove 13 in the middle of the heating disk body 9 is threadedly connected to the liquid guide section of the melting head 6; when liquid ice core water flows into the liquid guide section of the melting head 6, since the liquid guide section of the melting head 6 is located in the heat conduction zone of the heating disk body 9, the temperature of the liquid guide section of the melting head 6 will not decrease, thereby preventing the ice core water in the liquid guide section from freezing due to the decrease in temperature.

[0043] It should be noted that, in order to improve the overall performance of the heating tray 9, the material of the heating tray 9 is preferably aluminum.

[0044] See also Figure 6 , Figure 2 , Figure 5 , Figure 4 and Figure 3 The melting head 6 used for melting the ice core and the sample placement tube 5 includes a melting plate 14 and a liquid guide tube 15; wherein the melting plate 14 melts the ice core by heat radiation; and is used to connect with the sample placement tube 5 for placing the ice core; the liquid guide tube 15 is used to guide the ice core water that melts and flows into the bottom surface of the melting plate 14, so that the ice core water flows out of the melting plate 14 and is introduced into the first diversion branch 8, so as to assist the subsequent measurement process of the isotopes of the ice core water.

[0045] Specifically, the melting plate 14 is a disk-shaped structure with an open top, the open end of the top of the melting plate 14 is connected to the open end of the sample placement tube 5 by a thread, the middle of the bottom of the melting plate 14 is connected to the liquid inlet end of the liquid guide tube 15, and the liquid outlet end of the liquid guide tube 15 is connected to the liquid inlet end of the first diversion branch 8; wherein, in order to make the connection between the melting head 6 and the heating plate body 9 more stable, the liquid guide tube 15 is connected to the threaded heat conductive groove 13 in the middle of the heating plate body 9.

[0046] In actual use, when the heating disk 7 heats up the melting disk 14 through heat conduction to melt the ice core, the melted ice core changes from solid to liquid, and ice core water flows into the bottom of the melting disk 14. Since the middle position of the bottom of the melting disk 14 is connected to the liquid guide tube 15, the liquid ice core water flows into the first diversion branch 8 along the liquid guide tube 15, thereby assisting the subsequent measurement process of the ice core water isotopes.

[0047] It should be noted that, in order to increase the heat conduction rate of the melting head 6, the material of the melting head 6 is preferably copper, so as to shorten the time for the ice core to melt, and indirectly shorten the overall time of the measurement process.

[0048] It should be noted that the liquid guiding section of the melting head 6 is a liquid guiding tube 15 .

[0049] See also Figure 2 , Figure 6 and Figure 7 The first diversion branch 8 for conveying the ice core water melted by the melting head 6 to the defoaming component 2 includes a first diversion pipe 16, a sedimentation tank 17 and a filtrate pump 18; wherein, the first diversion pipe 16 and the filtrate pump 18 cooperate to discharge the melted ice core water to the sedimentation tank 17 and the defoaming component 2 in sequence; the sedimentation tank 17 is used to precipitate the melted ice core water, preliminarily improve the purity of the ice core water, and reduce the error in the subsequent measurement process; the filtrate pump 18 filters the supernatant after precipitation to further improve the purity of the ice core water.

[0050] Specifically, the liquid inlet end of the first guide tube 16 is connected to the liquid outlet end of the guide tube 15 constituting the melting head 6, the first guide tube 16 is sequentially connected to the sedimentation tank 17 and the filtrate pump 18, and the liquid outlet end of the first guide tube 16 is connected to the liquid inlet end of the defoaming component 2.

[0051] In actual use, when the ice core water after melting the melting head 6 enters the defoaming component 2 along the first diversion branch 8, the filtrate pump 18 is first turned on, and the ice core water enters the sedimentation tank 17 along the first diversion pipe 16, and then the filtrate pump 18 is turned off to allow the ice core water to settle for a period of time, and then the filtrate pump 18 is turned on again. The settled ice core water flows along the first diversion pipe 16 to the filtrate pump 18 for filtration, and the filtered ice core water flows along the first diversion pipe 16 into the defoaming component 2, completing the defoaming process of the ice core water.

[0052] It should be noted that the sedimentation tank 17 and the filtrate pump 18 are both existing technologies and have not been improved, so their structures are not described in detail.

[0053] See also Figure 1 and Figure 6 The debubbling component 2 used for debubbling liquid ice core water is a debubbler, and the debubbler input end is connected to the liquid outlet end of the first guide pipe 16 used to transport ice core water, so that the liquid ice core water containing a small amount of bubbles flows into the debubbler to complete the debubbling process, thereby preventing the generated bubbles from affecting the change of isotope values; then, after the ice core water is debubbled, in order to smoothly introduce the debubbled ice core water into the ice core water atomization and heating component 3, the debubbling output end of the debubbler is connected to the ice core water atomization and heating component 3 through the second guide branch 19.

[0054] Among them, the second guide branch 19 includes a third guide tube 21 and a second peristaltic pump 22; the liquid inlet end of the third guide tube 21 is connected to the debubbling output end of the debubbler, the second peristaltic pump 22 is connected to the third guide tube 21 pipeline, and the liquid outlet end of the third guide tube 21 is connected to the input end of the ice core water atomization and heating component 3.

[0055] In actual use, when the liquid ice core water after debubbling flows to the ice core water atomization and heating component 3, the second peristaltic pump 22 is turned on to allow the water after debubbling by the debubbler to flow along the third guide tube 21 into the ice core water atomization and heating component 3, completing the atomization process before measuring the isotopes of the ice core water, which not only shortens the measurement time but also improves the continuity of the measurement process.

[0056] It should be noted that the debubbler and the second peristaltic pump 22 are both existing technologies, and no improvement or design has been made thereto, so their structures are not described in detail.

[0057] It should be noted that, in the process of debubbling ice core water by the above debubbler, some waste liquid will inevitably appear in the debubbler. In order to collect this part of waste liquid, the waste liquid output end of the debubbler is connected to the second guide tube 12, and the first peristaltic pump 20 is connected to the second guide tube 12 pipeline, and the output end of the second guide tube 12 is connected to the waste liquid collection tank.

[0058] In actual use, when waste liquid is generated in the debubbler, the first peristaltic pump 20 is turned on to allow the waste liquid in the debubbler to flow along the second guide tube 12 into the waste liquid collecting tank, thereby completing the process of collecting the waste liquid. In this process, in order to recycle this part of the waste liquid, the waste liquid collecting tank can be connected to the filtering equipment through a pipeline to filter and recover the waste liquid in the waste liquid collecting tank for cleaning the equipment involved in the measurement process.

[0061] In actual use, after the debubbling component 2 debubbles the liquid ice core water, when it flows into the ice core water atomization component 3 through the second diversion branch 19, the atomizer 23 first atomizes the liquid ice core water to make it into misty water vapor, and then opens the regulating valve 26, and the dry air in the dry air container bottle 24 flows into the air purifier 27 along the fourth diversion pipe 25 to complete the purification, and then continues to flow into the storage chamber of the atomizer 23 for temporarily storing the mist along the fourth diversion pipe 25, and is mixed and dried with the ice core water mist that has been atomized and retained in the storage chamber before, and after being heated by the heating furnace 29 outside the atomizer 23, it is converted into gas and flows into the ice core water isotope measurement component 4, and the ice core water isotope measurement component 4 measures the isotopes in the gas to complete the measurement process of the isotopes in the ice core water.
