[0034] like Figures 1 to 9 As shown, the carbon emission measurement and analysis device provided by the embodiment of the present invention includes a measurement and analysis cylinder 1, a mounting box 2, a box cover 3, an air inlet outer filter 4 and an air outlet outer filter 5.

[0035] The installation box body 2 and the box cover 3 are combined to form a box-shaped structure, and the box cover 3 can be detachably installed on one side of the installation box body 2. The box-shaped structure is sequentially provided with a plurality of independent installation cavities 6 from top to bottom.

[0036] An air inlet channel 7 is provided on the side wall of the installation box 2 at the entrance of the installation cavity 6 , and an air inlet ring groove 8 is provided on the inner wall of the installation box 2 in the circumference of the air inlet channel 7 , and an air inlet outer filter 4 is installed in the air inlet ring groove 8 .

[0037] An air outlet channel 9 is provided on the side wall of the box cover 3 at the outlet of the installation cavity 6 , and an air outlet ring groove 10 is provided on the inner side wall of the box cover 3 in the circumference of the air inlet channel 7 , and an air outlet outer filter 5 is installed in the air outlet ring groove 10 .

[0038] Each mounting cavity 6 is provided with a metering and analyzing cylinder 1 , the end face of the air inlet end of the metering and analyzing cylinder 1 abuts against the circumference of the air inlet outer filter 4 , and the end face of the air outlet end of the metering and analyzing cylinder 1 abuts against the circumference of the air outlet outer filter 5 .

[0039] It should be noted that the mounting box 2 and the box cover 3 are easy to disassemble and install, so it is easy to remove or install the metering analysis cylinder 1. The multiple independent mounting cavities 6 correspond to the multiple metering analysis cylinders 1, and the multiple metering analysis cylinders 1 do not interfere with each other. The air inlet ring groove 8 is used to install the air inlet outer filter 4, and the air outlet ring groove 10 is used to install the air outlet outer filter 5. The air inlet outer filter 4 and the air outlet outer filter 5 can greatly reduce the particulate impurities in the gas from entering the metering analysis cylinder 1. The end face of the air inlet end of the metering analysis cylinder 1 and the circumferential abutment of the air inlet outer filter 4, and the end face of the air outlet end of the metering analysis cylinder 1 and the circumferential abutment of the air outlet outer filter 5, so the sealing effect is good. Such installation can also prevent particulate impurities in the gas from entering the mounting cavity 6, thereby further preventing particulate impurities in the gas from easily adhering to the carbon dioxide sensor, thereby ensuring the sensitivity of the metering analysis device.

[0040] In this embodiment, an air inlet scoop 11, an air inlet blower 12, a metering and analysis module 13, a one-way vent valve 14 and an air outlet scoop 15 are sequentially arranged in the metering and analysis cylinder 1 along the air inlet direction.

[0049] In this embodiment, the installation box 2 is provided with detachable sealing covers 18 at both the air inlet of the air inlet channel 7 and the air outlet of the air outlet channel 9 .

[0050] It should be noted that the sealing cover 18 and the mounting box 2 are threadedly connected or snap-connected at the air inlet of the air inlet channel 7 and the air outlet of the air outlet channel 9, so that the sealing cover 18 can seal the mounting cavity 6 when the metering and analyzing cylinder 1 is not in use.

[0051] In this embodiment, a plurality of docking posts 19 are provided on the end surfaces where the mounting box body 2 and the box cover 3 cooperate with each other, and threaded holes are provided at the centers of the docking posts 19 .
