[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
[0025] Embodiment one
[0026] The first embodiment of the present application provides a carbon emission collector, as shown in the figure, which comprises: an air inlet pipe 1, an air outlet pipe 2 and a sampling wheel 3. Figure 1
[0027] Among them, as shown in the figure, Figure 2 , Figure 3 andFigure 4 As shown in Figure 1 , Figure 4 and Figure 5 , the sampling wheel 3 is rotatably arranged between the intake pipe 1 and the exhaust pipe 2, and in combination with Figure 6 , the sampling wheel 3 has flow passages 31 and sampling passages 32 along the axial direction thereof, which are respectively communicated with the intake passages 11 and the exhaust passages 21.
[0028] In addition, as shown in Figure 1 and Figure 2 , the number of the intake sampling passages 12 and the exhaust sampling passages 22 is the same and corresponds uniquely, and when the sampling wheel 3 is rotated to the first preset position, each sampling passage 32 is respectively communicated with one of the intake sampling passages 12 and one of the exhaust sampling passages 22. When the sampling wheel 3 is rotated to the second preset position, as shown in Figure 4 , each sampling passage 32 is respectively disconnected from each intake sampling passage 12 and each exhaust sampling passage 22.
[0029] As can be seen from the above, since the carbon emission collector comprises the intake pipe 1, the exhaust pipe 2 and the sampling wheel 3, the intake pipe can be connected to the exhaust pipeline of the factory, and in the general state, the sampling wheel 3 can be rotated to the first preset position, at which time the exhaust gas discharged from the exhaust pipeline can be sequentially discharged through the intake passages 11 of the intake pipe 1, the flow passages 31 of the sampling wheel 3 and the exhaust passages 21 of the exhaust pipe 2, and since at this time each sampling passage 32 of the sampling wheel 3 is respectively communicated with one of the intake sampling passages 12 and one of the exhaust sampling passages 22, part of the exhaust gas can also be sequentially discharged through each intake sampling passage 12, each sampling passage 32 and each exhaust sampling passage 22. When sampling of the exhaust gas is needed, the sampling wheel 3 can be rotated to the second preset position, so that at this time each sampling passage 32 of the sampling wheel 3 can be respectively disconnected from each intake sampling passage 12 and each exhaust sampling passage 22, so as to seal the sample gas to be sampled in each sampling passage 32 of the sampling wheel 3, so as to complete the multi-point sampling of the exhaust gas, thereby providing a basis for calculating the total amount of carbon emission in the exhaust gas when calculating the carbon emission, so as to greatly reduce the error generated when calculating the carbon emission.
[0030] Specifically, in some embodiments, in the intake pipe 1, as shown in Figure 3 , the intake passages 11 are arranged along the axial direction of the intake pipe 1, and meanwhile, the intake sampling passages 12 are arranged in multiple numbers and are sequentially arranged around the axial direction of the intake pipe 1. Secondly, in the exhaust pipe 2, as shown in Figure 2As shown, the air outlet passage 21 is arranged along the axial direction of the air outlet pipe 2, and the air outlet sampling passage 22 is arranged in multiple, and each air outlet sampling passage 22 is arranged in turn around the axial direction of the air outlet pipe 2. Finally, in the sampling wheel 3, as shown in Figure 6 As shown, the sampling channel 32 is arranged in multiple, and each sampling channel 32 is arranged in turn around the axial direction of the sampling wheel 3.
[0031] It is not difficult to see that since the air inlet sampling passage 12, the air outlet sampling passage 22 and the sampling channel 32 are arranged in multiple, and each sampling channel 32 is arranged in turn around the axial direction of the sampling wheel 3, so that the sampling wheel 3 can realize multi-point sampling of the exhaust gas in the exhaust pipe. For example, as shown in Figure 1 、 Figure 2 and Figure 3 As shown, the air inlet pipe 1 and the air outlet pipe 2 are both flat pipes, and the air inlet sampling passage 12 and the air outlet sampling passage 22 are both arranged in four, and the four air inlet sampling passages 12 are respectively arranged around the air inlet pipe 1 along the axial direction of the air inlet pipe 1, and similarly, the four air outlet sampling passages 22 can also be respectively arranged around the air outlet pipe 2 along the axial direction of the air outlet pipe 2. For example, as shown in Figure 2 and Figure 3 As shown, the four air inlet sampling passages 12 can be arranged symmetrically with each other along the axial direction of the air inlet pipe 1 as the symmetry axis, and the four air outlet sampling passages 22 can also be arranged symmetrically with each other along the axial direction of the air outlet pipe 2 as the symmetry axis, and the sampling channel 32 can be arranged in six, and the six sampling channels 32 are arranged equidistantly around the axial direction of the sampling wheel 3. As can be seen, in the default state, the four sampling channels 32 of the sampling wheel 3 are respectively communicated with each air inlet sampling passage 12 and each air outlet sampling passage 22, so that after the sampling wheel 3 is rotated by 60 degrees, four sampling channels 32 on the sampling wheel 3 can be communicated with each air inlet sampling passage 12 and each air outlet sampling passage 22, to meet the flow of exhaust gas in each sampling channel 32. When it is necessary to collect exhaust gas in the exhaust pipe, the sampling wheel 3 can be rotated by 30 degrees, so that each sampling channel 32 of the sampling wheel 3 can be disconnected from the air inlet sampling passage 12 and the air outlet sampling passage 22, so that the exhaust gas flowing through each sampling channel 32 of the sampling wheel 3 cannot flow, but is completely sealed in each sampling channel 32 of the sampling wheel 3 as a sample gas, so that each sampling channel 32 of the sampling wheel 3 can realize multi-point sampling of the exhaust gas in the exhaust pipe.
[0032] In addition, in some embodiments, as shown in Figure 4 The carbon emission collector further comprises a sealing bearing seat 4, and the sealing bearing seat 4 is sleeved on the sampling wheel 3 and is used for sealing each sampling channel 32 when the sampling wheel 3 is rotated to the second preset position, so that each sampling channel 32 is disconnected from each air inlet sampling passage and each air outlet sampling passage. Specifically, in some embodiments, as shown in Figure 4As shown, the sealing bearing seat 4 comprises: a front end seat body 41, a rear end seat body 42 and a bearing 43. Among them, the front end seat body 41 and the rear end seat body 42 are arranged opposite to each other along the axis direction of the sampling wheel 3, and the front end seat body 41 and the rear end seat body 42 are respectively sleeved on both sides of the sampling wheel 3, that is, the front end seat body 41 is used to seal one side of the sampling wheel 3 relative to the air inlet pipe 1, and the rear end seat body 42 is used to seal the other side of the sampling wheel 3 relative to the air outlet pipe 2. Finally, as shown in Figure 4 As shown, the bearing 43 is sleeved between the sampling wheel 3 and the rear end seat body 42, and the bearing 43 can be used for the sampling wheel 3 to rotate around its axis direction, so as to improve the rotation performance of the sampling wheel 3. As can be seen, the front end seat body 41 and the rear end seat body 42 can ensure the sealing performance of each sampling channel 32 when the sampling wheel 3 rotates to the second preset position, so as to avoid leakage of the exhaust gas entering the sampling channel 32 from both sides of the sampling wheel 3.
[0033] In addition, as a preferred aspect, in other embodiments, as shown in Figure 1 and Figure 4 The carbon emission collector further comprises a driving device 5 connected with the sampling wheel 3, and the driving device 5 is used to receive the driving instruction sent by the main control module 6 of the carbon emission detection device and drive the sampling wheel 3 to rotate according to the received driving instruction. As can be seen, through the driving of the sampling wheel 3 by the driving device 5, the sampling wheel 3 can realize automatic sampling of the exhaust gas. Specifically, as shown in Figure 1 , Figure 4 and Figure 5 The driving device 5 comprises: a motor 51, a driven gear 53 and a driving gear 52. Among them, as shown in Figure 7 The motor 51 is in communication connection with the main control module 6 of the carbon emission detection device, and the motor 51 can receive the driving instruction sent by the main control module 6. Secondly, the driven gear 53 is sleeved on the sampling wheel 3, and the driven gear 53 is coaxially fixed with the sampling wheel 3. Finally, the driving gear 52 is coaxially connected with the main shaft of the motor 51, and the driving gear 52 is also engaged with the driven gear 53. Thus, when the motor 51 receives the driving instruction sent by the main control module 6, the driving gear 52 can be driven to rotate, and the driving gear 52 can drive the driven gear 53 to rotate by engaging with the driven gear 53 when rotating, and further drive the sampling wheel 3 coaxially fixed with the driven gear 53 to rotate, so that the sampling wheel 4 can realize multi-point sampling of the exhaust gas.
[0034] And in order to realize the installation of the driving device 5, as shown in Figure 1 , Figure 4 and Figure 5As shown, the carbon emission collector further comprises a rack 7, and the rack 7 is connected with the air inlet pipe 1 and the air outlet pipe 2 respectively, and the rack 7 is used for supporting the air inlet pipe 1 and the air outlet pipe 2. Wherein, the motor 51 is detachably arranged on the rack 7, for example, the motor 51 and the rack 7 can be detachably connected through a mounting plate, a bolt or the like locking piece, and through the detachable connection between the rack 7 and the motor 51, the rack 7 can support and fix the driving device 5, so as to improve the stability of the driving device 5 when driving the sampling wheel 3.
[0035] And, as shown in Figure 1 and Figure 4 , the rack 7 comprises a first support plate 71, a second support plate 72 and a bottom plate 73. Wherein, the first support plate 71 and the second support plate 72 are arranged opposite to each other, and the first support plate 71 is connected with the air inlet pipe 1, while the second support plate 72 is connected with the air outlet pipe 2, in addition, the bottom plate 73 is arranged between the first support plate 71 and the second support plate 72, and the bottom plate 73 is connected with the first support plate 71 and the second support plate 72 respectively, so that the first support plate 71 can be used to support the air inlet pipe 1, and at the same time, the second support plate 72 can be used to support the air outlet pipe 2, and in combination with Figure 1 and Figure 4 , the motor 51 is also detachably arranged on the bottom plate 73, so that the driving gear 52 coaxially connected with the main shaft of the motor 51 can be engaged with the driven gear 53 to ensure that the driving device 5 can stably drive the sampling wheel 3.
[0036] Embodiment two
[0037] Embodiment two of the utility model relates to a carbon emission detection device, as shown in Figure 7 , comprising: the carbon emission collector as claimed in embodiment one, at least one heating element 8, at least one temperature detection module 9 and a main control module 10.
[0038] Wherein, in combination with Figure 4 , each heating element 8 is the same as the number of sampling channels 32 of the sampling wheel 3, and is uniquely corresponding, each heating element 8 is arranged in the uniquely corresponding each sampling channel 32 respectively, and each heating element 8 is used to heat the sample gas entering the uniquely corresponding each sampling channel 32 when the sampling wheel 3 rotates to the second preset position.
[0039] Secondly, in combination with Figure 4 , the temperature detection module 9 is the same as the number of sampling channels 3, and is uniquely corresponding, each temperature detection module 9 is used for detecting the thermal conductivity of the sample gas entering the uniquely corresponding each sampling channel 32 respectively.
[0040] Finally, in combination with Figure 7As shown, the main control module 4 is connected to each heating element 8 and each temperature detection module 9. The main control module 4 is used to obtain the thermal conductivity measured by each temperature detection module 9, and to obtain the carbon dioxide content of the sample gas entering each sampling channel 32 based on the obtained thermal conductivity measured by each temperature detection module 9.
[0041] As can be seen from the above, by heating each sampling channel 32 with heating element 8, the temperature detection module 9 can effectively detect the thermal conductivity of the sample gas in the sampling channel 3. Simultaneously, by acquiring the thermal conductivity measured by each temperature detection module 9, the main control module 10 can directly obtain the carbon dioxide content of the sample gas in each sampling channel. Therefore, when calculating carbon emissions, the average carbon dioxide content in each sampling channel 32 can be calculated first to accurately determine the total carbon emissions per unit time. For example, the main control module 10 has a preset table relating the thermal conductivity of the sample gas to the carbon dioxide content. This means that different thermal conductivity levels correspond to different carbon dioxide contents, allowing the main control module 10 to directly obtain the carbon dioxide content in the sample gas after obtaining the thermal conductivity measured by the temperature detection module 9, thus providing a basis for calculating the total carbon emissions in the exhaust gas.
[0042] Specifically, in some embodiments, the heating element 8 may be a thermocouple or a resistance temperature detector (RTD), and as... Figure 4 As shown, the heating element 8 can be placed at the inlet end of each sampling channel 32. Of course, in other embodiments, the heating element 8 can also be directly placed inside each sampling channel 32, so that each heating element 8 can heat the exhaust gas in each sampling channel 32. Secondly, as Figure 4 As shown, each temperature detection module 9 includes two temperature sensors 91. In any temperature detection module 9, the two temperature sensors 91 are respectively set at both ends of each uniquely corresponding sampling channel 32. Therefore, when the main control module 9 obtains the temperature of the exhaust gas measured by each sampling channel 32, it can use the average value of the thermal conductivity measured by the two temperature sensors 9 as the thermal conductivity measured by the current temperature detection module 9, thereby further improving the accuracy of the temperature detection module 9 in detecting the thermal conductivity of the sample gas.
[0043] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate a better understanding of the present application. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of this application can be substantially achieved. 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 this application.
