DETAILED DESCRIPTION

[0016] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0017] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] like Figure 1-2As shown, the highway carbon emission monitoring device includes a box body 1, a first air inlet 2 is provided on the side of the box body 1, a support net 5 is provided in the box body 1, a drying bag 6 is placed on the support net 5, and the drying bag 6 is made of magnesium perchlorate powder bag. A pneumatic conveying device 7 is provided below the support net 5. The pneumatic conveying device 7 adopts equipment such as an exhaust fan or a fan. The pneumatic conveying device 7 forms an airflow with a certain pressure from the outside air and draws it into the box body 1, and enters the bottom of the support net 5 through the drying bag 6. The gas is dried when passing through the drying bag 6, and the drying bag 6 can also filter large particle pollutants in the gas.

[0019] In addition to the above components, it also includes a monitoring tube 10, the interior of the monitoring tube 10 is a monitoring room, the monitoring tube 10 has a second air inlet 8 and a second air outlet 12 near its two ends, the air outlet of the pneumatic conveying device 7 is connected to the second air inlet 8, so that air is blown into the monitoring tube 10, an infrared light source 9 is provided at the left end of the monitoring tube 10, and a detector 11 is provided at the other end, where the detector 11 is a thin film capacitive infrared detector 11, when the carbon dioxide in the monitoring room absorbs the light of a specific wavelength emitted by the infrared light source 9, the gas temperature rises, resulting in a pressure increase in the monitoring room. As the force increases, the distance between the two electrodes of the capacitor will change, and the capacitance value will change accordingly. The detector 11 is connected to the analog-to-digital converter 14 at the end of the monitoring tube through an electric wire. The analog-to-digital converter 14 converts the signal into a digital signal for output. The analog-to-digital converter 14 is connected to the display 15, and the signal is displayed on the display 15. The display 15 is arranged on the outer surface of the box 1. The carbon concentration of the highway can be directly obtained by observation, which can be used as an indicator for carbon emission monitoring. The carbon emissions can be monitored in real time. The second air outlet 12 extends to the outside of the box 1 through the air pipe 13, and the gas passing through the monitoring room is discharged from the air pipe 13.

[0020] It should be noted that the above-mentioned pneumatic conveying equipment 7 is a low-power, low-frequency, low-speed exhaust fan or blower. The role of the pneumatic conveying equipment 7 here is only to allow external air to enter the monitoring room, and it is not used for other functions. Therefore, the low-power, low-speed pneumatic conveying equipment 7 is sufficient to meet the needs.

[0021] Furthermore, in order to improve the drying effect on the incoming air, the above-mentioned drying bags 6 are arranged in plurality, and the plurality of drying bags 6 are laid flat and cover the mesh surface of the supporting net 5. Not only can the gas pass through the drying bags 6 to achieve the purpose of drying, but also large particle pollutants can be filtered in the gaps between the drying bags 6 to achieve a rough purification effect.

[0022] Furthermore, in order to increase the amount of air entering the box body 1 from the road, a plurality of the first air inlets 2 are provided, and the plurality of first air inlets 2 are arranged at intervals along the side surface of the box body 1 .

[0023] Furthermore, the infrared light source 9 adopts nickel-chromium wire, which is connected to an external power source through an electric wire. After being powered on and heated, it can emit infrared light with a wavelength of 3-10μm, which includes the strong absorption peak of carbon dioxide gas at 4.26μm. The detector 11 can display the absorption of infrared light by carbon dioxide.

[0024] Furthermore, a rainproof plate 3 is provided on the top of the box body 1, and the rainproof plate 3 can prevent rainwater from entering the box body 1 and corroding the internal components.

[0025] Furthermore, a warning light 4 is provided above the rain shield 3, and the warning light 4 can give a signal to pedestrians or other personnel to avoid collision or damage to the device.

[0026] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.
