[0002] In the field of carbon monitoring, carbon emission and settlement, the monitoring of carbon dioxide emission is an important link. In the waste gas emission of the production department, carbon dioxide is discharged mixed with other gases. At this time, the monitoring of carbon dioxide concentration is crucial to carbon emission and settlement. The detection of carbon dioxide concentration in the air can adopt the method of thermal conductivity determination. Because the thermal conductivity of carbon dioxide is significantly lower than that of nitrogen and oxygen, the main components in the air, the actual thermal conductivity of the emitted gas is determined, and the thermal conductivity of carbon dioxide mixed with different proportions of air in the atmosphere is compared, and the carbon dioxide content of the current emitted gas can be obtained. However, for factories with huge energy consumption, a large amount of carbon dioxide gas will be mixed in the waste gas when the factory waste gas is discharged. At present, the flowing carbon dioxide gas cannot be reliably monitored, and the environmental temperature affects the physical properties of the mixed gas, causing inaccurate measurement. Therefore, it will cause a large error in the final carbon emission accounting. CONTENT OF THE UTILITY MODEL

[0027] Embodiment one
[0028] The first embodiment of the utility model provides a kind of carbon emission collection device, as shown in the figure, the carbon emission collection device includes: shell 1, air inlet pipe 2, air outlet pipe 3, driving assembly 4 and sliding block 5. Figure 1
[0029] As shown in the figure, shell 1 has accommodating space 14 in it, and the opening 11 is arranged at any side of shell 1. Secondly, air inlet pipe 2 and air outlet pipe 3 are arranged on the two sides of shell 1 along the length direction of opening 11. In addition, sliding block 5 is used to slide into or slide out of shell 1 through opening 11, and as shown in the figure and the figure, first air passage 51 and second air passage 52 are arranged along the sliding direction of sliding block 5. Finally, driving assembly 4 is connected with sliding block 5, and the driving assembly 4 is used to drive sliding block 5 to slide into or slide out of shell 1. Figure 1 Figure 5 When sliding block 5 slides to the first preset position towards the outside of shell 1, as shown in the figure, first air passage 51 can be communicated with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, second air passage 52 is disconnected with air inlet pipe 2 and air outlet pipe 3 respectively. When sliding block 5 slides to the second preset position towards the inside of shell 1, as shown in the figure, second air passage 52 can be communicated with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, first air passage 51 is disconnected with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, the sample gas flowing through first air passage 51 is sealed in first air passage 51. Figure 2 Figure 3
[0030] When sliding block 5 slides to the first preset position towards the outside of shell 1, as shown in the figure, first air passage 51 can be communicated with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, second air passage 52 is disconnected with air inlet pipe 2 and air outlet pipe 3 respectively. When sliding block 5 slides to the second preset position towards the inside of shell 1, as shown in the figure, second air passage 52 can be communicated with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, first air passage 51 is disconnected with air inlet pipe 2 and air outlet pipe 3 respectively, and at the same time, the sample gas flowing through first air passage 51 is sealed in first air passage 51. Figure 5 Figure 4
[0031] As can be seen from the above, since the shell 1 is provided with the opening 11 on any side thereof, the sliding block 5 slides into or out of the shell 1 through the opening 11, and the air inlet pipe 2 and the air outlet pipe 3 are arranged on the two sides of the shell 1 along the length direction of the opening 11, respectively, when the sliding block 5 slides to the first preset position towards the outside of the shell 1, the first air passage 51 of the sliding block 5 can be in communication with the air inlet pipe 2 and the air outlet pipe 3, respectively, while the second air passage 52 can be disconnected from the air inlet pipe 2 and the air outlet pipe 3, respectively. When the sliding block 5 slides to the second preset position towards the inside of the shell 1, the second air passage 52 of the sliding block 5 can be in communication with the air inlet pipe 2 and the air outlet pipe 3, respectively, while the first air passage 51 can be disconnected from the air inlet pipe 2 and the air outlet pipe 3, respectively. Therefore, in application, the shell 1 can be connected to the waste gas pipeline of the factory, the first air passage 51 can be used as the gas passage for collecting sample gas, and the second air passage can be used as the gas passage for normal exhaust of waste gas of the factory. In the default state, the sliding block 5 can be first driven to slide to the first preset position by the driving assembly 4, at this time, the waste gas discharged from the waste gas pipeline can be discharged outward through the first air passage 51 of the sliding block 5, when the discharge of the waste gas tends to be stable, the sliding block 5 can be driven to slide to the second preset position by the driving assembly 4, so that the waste gas flowing through the first air passage at this time can be used as sample gas and sealed in the first air passage 51, thereby laying a foundation for accurate detection of the carbon dioxide content in the sample gas. At the same time, since the second air passage 52 can be in communication with the air inlet pipe 2 and the air outlet pipe 3 at this time, the normal exhaust of waste gas of the factory will not be affected. This collection method can realize accurate detection of flowing carbon dioxide gas.
[0032] Specifically, in some embodiments, as shown in Figure 1 and Figure 5 , the opening 11 extends in the direction of the sliding block 5 towards the inside of the shell 1, so that the accommodation space 14 for the sliding block 5 to slide is formed in the shell 1. And, as shown in Figure 4 and Figure 5 , the shell 1 is provided with the first connecting hole 12 corresponding to one end of the accommodation space 14, which can be connected to the air inlet pipe 2, and part of the air inlet pipe 2 is inserted into the first connecting hole 12, so that the air inlet pipe 2 can be detachably connected to the shell 1. Similarly, as shown in Figure 4 and Figure 5 , the shell 1 is provided with the second connecting hole 13 corresponding to the other end of the accommodation space 14, which can be connected to the air outlet pipe 3, and part of the air outlet pipe 3 is inserted into the second connecting hole 13, so that the air outlet pipe 3 can be detachably connected to the shell 1. And, in order to ensure the sealing performance of the air inlet pipe 2 and the air outlet pipe 3 after being connected to the shell 1, in some embodiments, the air inlet pipe 2 and the air outlet pipe 3 can be in interference fit with the first connecting hole 12 and the second connecting hole 13, respectively, or in other embodiments, flexible sealing rings (not shown in the figure) can be arranged in the first connecting hole 12 and the second connecting hole 13, respectively, so as to ensure the sealing performance of the air inlet pipe 2 and the air outlet pipe 3 after being connected to the shell 1, and avoid gas leakage.
[0033] In addition, in some embodiments, as shown in Figure 4 and Figure 5 , the air inlet pipe 2 has a first limiting protrusion 21 protruding at least partially in the direction of its axis, and the first limiting protrusion 21 is used to abut against the outer side of the shell 1 when the air inlet pipe 2 is partially inserted into the first connecting hole 12. Similarly, as shown in Figure 4 and Figure 5 , the air outlet pipe 3 has a second limiting protrusion 31 protruding at least partially in the direction of its axis, and the second limiting protrusion 31 is used to abut against the outer side of the shell 1 when the air outlet pipe 3 is partially inserted into the second connecting hole 22. It can be seen that the first limiting protrusion 31 and the second limiting protrusion 22 can limit the installation position of the air inlet pipe 2 and the air outlet pipe 3 in the shell 1.
[0034] In addition, as a preferred embodiment, in other embodiments, a first sealing ring (not shown in the figure) is arranged at each end of the first air passage 51, and the first sealing ring can form a seal between the air inlet pipe 2 and the air outlet pipe 3 when the slider 5 slides to the first preset position, so as to further improve the sealing performance of the first air passage 51 when the first air passage 51 is connected to the air inlet pipe 2 and the air outlet pipe 3. Similarly, as shown in Figure 1 , a second sealing ring (not shown in the figure) is arranged at each end of the second air passage 52. The second sealing ring can form a seal between the air inlet pipe 2 and the air outlet pipe 3 when the slider 5 slides to the second preset position, so as to further improve the sealing performance of the second air passage 52 when the second air passage 52 is connected to the air inlet pipe 2 and the air outlet pipe 3.
[0035] In addition, it is worth mentioning that, in other embodiments, as shown in Figure 1 , the air inlet pipe 2 and the air outlet pipe 3 are coaxially arranged, and therefore, corresponding to the positions of the air inlet pipe 2 and the air outlet pipe 3 in the shell 1, as shown in Figures 2 to 5 , the first air passage 51 and the second air passage 52 are both straight passages. Of course, in other embodiments, the air inlet pipe 2 and the air outlet pipe 3 can also be arranged in a non-coaxial manner, for example, the axis of the air inlet pipe 2 and the axis of the air outlet pipe 3 are parallel to each other, and at this time, corresponding to the positions of the air inlet pipe 2 and the air outlet pipe 3 in the shell 1, the first air passage 51 and the second air passage 52 can adopt an arc-shaped passage structure. Of course, the above-mentioned first air passage 51 and second air passage 52 are only taken as examples of straight passages and arc-shaped passages for illustration, and in other embodiments, the first air passage 51 and the second air passage 52 can also adopt other structures, and in the present embodiment, the structure of the first air passage 51 and the second air passage 52 is not specifically limited.
[0036] In addition, in order to enable the driving assembly 4 to drive the slider 5 to slide into or out of the shell 1, in some embodiments, as shown in Figures 1 to 5As shown, the driving assembly 4 comprises a push rod 41 and a driving component 42. The push rod 41 is connected with the sliding block 5 and extends in a direction perpendicular to the sliding block 5, and the driving component 42 is connected with the push rod 41 and used to drive the push rod 41 so that the push rod 41 can drive the sliding block to slide into or out of the shell 1. For example, in some embodiments, as shown in Figure 1 As shown, the driving component 42 can be a screw rod driving component, and the push rod 41 is slidably arranged on the driving component 42, that is, the push rod 41 is arranged with a sliding groove (not shown in the figure) in a direction perpendicular to the sliding block 5, and the driving component 42 is arranged with a sliding rail 43 which can be embedded in the sliding groove, and the screw rod of the driving component 42 is connected with the push rod 41, so that when the driving component 42 drives the push rod 41, the driving component 42 can convert the rotary motion of the screw rod into the linear motion of the push rod 41 by the sliding cooperation of the sliding block 5 and the sliding rail 43, so that the push rod 41 can drive the sliding block 5 to slide into or out of the shell 1 through the opening 11 under the driving of the driving component 42.
[0037] Embodiment two
[0038] Embodiment two of the utility model relates to a carbon emission detection mechanism, like Figure 1 As shown, the carbon emission detection mechanism comprises the carbon emission collection device, a heating module 6, a temperature detection module 7 and a main control module 8 as described in embodiment one.
[0039] Among them, in combination with Figure 2 As shown, the heating module 6 is arranged in the first air duct 51 of the sliding block 5, and the heating module 6 is used to heat the exhaust gas flowing through the first air duct 51. Secondly, the temperature detection module 7 is arranged in the first air duct 51, and the temperature detection module 7 is used to detect the thermal conductivity of the exhaust gas flowing through the first air duct 51.
[0040] In addition, in combination with Figure 6 As shown, the main control module 8 is respectively connected with the heating module 6, the temperature detection module 7 and the driving assembly 4, and the main control module 8 is used to send driving instructions to the driving assembly 4, so that the driving assembly 4 drives the sliding block 5 to slide between the first preset position and the second preset position.
[0041] In application, when the sliding block 5 slides to the second preset position, in combination with Figure 6 As shown, the heating module 6 is opened, so that the heating module 6 can heat the sample gas sealed in the first air duct 51. And when the heating module 6 heats the sample gas, the thermal conductivity of the sample gas in the first air duct 51 can be detected by the temperature detection module 7 in real time, and the main control module 8 can obtain the thermal conductivity measured by the temperature detection module 7, and obtain the content of the diatomic carbon in the sample gas according to the obtained thermal conductivity.
[0042] As can be seen from the above, by heating the sample gas in each first gas channel 51 by the heating module 6, the temperature detection module 7 can effectively detect the thermal conductivity of the sample gas in the first gas channel 51, and the main control module 8 can obtain the thermal conductivity detected by the temperature detection module 7, so that the main control module 8 can obtain the content of carbon dioxide in the sample gas in the first gas channel 51. For example, the main control module 8 is pre-provided with a comparison table between thermal conductivity and carbon dioxide content, that is, the sample gas at different thermal conductivities can correspond to different carbon dioxide contents, so that the main control module 8 can obtain the carbon dioxide content in the sample gas after obtaining the thermal conductivity detected by the temperature detection module 7, thereby providing a basis for calculating the total amount of carbon emissions in the exhaust gas.
[0043] Specifically, in some embodiments, as shown in Figure 1 , the heating module 6 can be a thermocouple or a thermal resistor, and as shown in Figure 2 , the heating module 6 can be arranged at the inlet end of the first gas channel 51, that is, the heating module 6 can be arranged at one end of the first gas channel 51 close to the air inlet pipe 2, so that the exhaust gas can be heated by the heating module 6 at the first time when entering the first gas channel 51, thereby ensuring the accuracy of the main control module 8 in obtaining the carbon dioxide content in the sample gas. Of course, in other embodiments, the heating module 6 can also be arranged directly at the outlet end of the first gas channel 51 or at other positions in the first gas channel 51. Secondly, as shown in Figure 2 , the temperature detection module 7 includes a plurality of temperature sensors 71, and each temperature sensor 71 is arranged equidistantly along the length of the first gas channel 51, so that when the main control module 8 obtains the temperature of the exhaust gas detected by each temperature sensor 71, the average value of the thermal conductivities detected by the plurality of temperature sensors 71 can be taken as the thermal conductivity detected by the current temperature detection module 7, thereby improving the accuracy of the temperature detection module 7 in detecting the thermal conductivity of the sample gas.
[0044] In addition, since the calculation of the thermal conductivity of the sample gas is greatly affected by the ambient temperature, in order to ensure the accuracy of the temperature detection module 7 in detecting the thermal conductivity of the sample gas, as a preferred scheme, in some embodiments, as shown in Figure 3 , Figure 4 and 5 , the carbon emission detection mechanism further includes a refrigeration module 9, and the refrigeration module 9 is arranged on the housing 1 and is in communication connection with the main control module 8. Therefore, when the sliding block 5 slides to the second preset position and before the main control module 8 turns on the heating module 6, the main control module 8 can first turn on the refrigeration module 9, so that the refrigeration module 9 can cool the sample gas sealed in the first gas channel 51 to a reference temperature, thereby greatly reducing the influence of the external environment temperature on the sample gas.
[0045] Furthermore, it is worth mentioning that, in some embodiments, as shown inFigure 3 、 Figure 4 and 5 As shown in FIG. 13, the refrigeration module 9 can be arranged on the side of the housing 1 close to the first air passage 51, and the opening 11 can be arranged on the side of the housing 1 close to the second air passage 52. In this arrangement, when the slider 2 slides to the second preset position, the refrigeration module 9 can be closer to the first air passage 51, so that the refrigeration module 9 can more quickly cool the sample gas sealed in the first air passage 51 to the reference temperature. In some embodiments, as shown in FIG. 14, the refrigeration module 9 can include a plurality of semiconductor refrigeration pieces 91. Of course, in other embodiments, the refrigeration module 9 can have other structures, and in the present embodiment, the structure of the refrigeration module 9 is not specifically limited. Figure 3

However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of the present application can be basically realized. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of the present application.
