DETAILED DESCRIPTION

[0025] 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 described clearly and completely below. Obviously, the described embodiments are some 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 any creative effort also belong to the scope of protection of the present application.

[0026] As shown in Figures 1-3 , the present application discloses a detection device for carbon emission, which comprises an outer box body 1, a partition plate 2 is fixedly arranged in the outer box body 1, the partition plate 2 divides the internal space of the outer box body 1 into two independent spaces, a detection element 3, a control module 4 and an energy storage module 5 are installed in the space below the partition plate 2 in the outer box body 1, the detection head of the detection element 3 penetrates the partition plate 2 in the vertical direction and is fixedly connected with the partition plate 2;

[0027] A detection chamber 6 is arranged in the space above the partition plate 2 in the outer box body 1, and the detection chamber 6 is respectively provided with an air extraction unit 7 and a filter unit 8 on opposite sides; ​

[0028] The outer box body 1 is provided with an air inlet cylinder 9 at the top, and the inner space of the air inlet cylinder 9 is communicated with the space on the side of the filter unit 8 away from the detection chamber 6.

[0029] In the above embodiment, the inner space of the outer box body 1 is divided into two independent spaces by the partition plate 2, the space below is used for installing the electrical elements such as the detection element 3, the control module 4 and the energy storage module 5 which are electrically connected together, a detection chamber 6 is arranged at the position opposite to the detection head of the detection element 3 above the partition plate 2, an air extraction unit 7 and a filter unit 8 are arranged on the opposite sides of the detection chamber 6 along the length direction of the partition plate 2, respectively, wherein the upper side of the filter unit 8 away from the air extraction unit 7 is provided with an air inlet cylinder 9, and the air inlet cylinder 9 is fixedly installed at the corresponding position on the top plate of the outer box body 1. Since the upper port of the air inlet cylinder 9 is located outside the outer box body 1, and the lower port extends to the space above the partition plate 2 on the side of the filter unit 8 away from the air extraction unit 7, when the air extraction unit 7 is started, the air can be guided to enter the inner space of the outer box body 1 from the air inlet cylinder 9. After the air enters the inner space of the outer box body 1, it will first pass through the filter unit 8 in the horizontal direction, and the filter unit 8 can separate the water vapor, dust and some aerosols in the air to ensure that the air entering the detection chamber 6 will not interfere with the detection effect of the detection element 3. Since the water vapor molecules have strong absorption peaks in the infrared wave band, which overlap with the characteristic absorption peaks of carbon dioxide and other greenhouse gases, if not treated, it will cause the detection element 3 to misjudge the concentration of the target gas. When the dust and aerosols flow through the detection chamber 6 along with the air, the light beam emitted by the detection element 3 will vibrate due to the turbulent motion of the air, thereby causing the detection result of the carbon emission concentration to deviate. Because the present application filters and removes impurities from the air to be detected by the filter unit 8 before introducing the air into the detection chamber 6 by the air extraction unit 7, the accuracy of the final detection result of the detection equipment is effectively improved.

[0030] Further, as shown in Figures 2-4 , the filter unit 8 includes a mounting frame 81, and a primary filter core 82 and a secondary filter core 83 are inserted into the mounting frame 81 in sequence and side by side along the length direction of the partition plate 2. The primary filter core 82 is used for filtering the dust and aerosols in the air, and the secondary filter core 83 is used for filtering the water vapor in the air.

[0031] In the above embodiment, the mounting frame 81 of the application is a rectangular structure welded by a plurality of mutually perpendicular metal rods. The first filter element 82 and the second filter element 83 are sequentially inserted along the length direction of the partition plate 2 inside the mounting frame 81. The first filter element 82 is directed away from the air suction unit 7 inside the mounting frame 81, and the second filter element 83 is directed towards the air suction unit 7 inside the mounting frame 81. In this way, when the air flows towards the detection chamber 6, it will first pass through the first filter element 82 to remove dust and aerosols with larger particle sizes, and then pass through the second filter element 83 to remove water vapor with smaller particle sizes. A spacing frame can be added between the first filter element 82 and the second filter element 83 to facilitate quick positioning of the first filter element 82 and the second filter element 83.

[0032] Further, the first filter element 82 is a HEPA filter.

[0033] In the above embodiment, the HEPA filter, also known as high-efficiency particulate air filter, has a filtration efficiency of ≥99.97% for particles with a diameter of ≥0.3 microns. The particle size of dust in the air is about 5 microns, and the particle size of common aerosols that affect detection is about 0.5-1 microns. Therefore, when the air passes through the HEPA filter of the first filter element 82 of the application, most of the dust and aerosols can be trapped. The HEPA filter can also be designed with creases to increase the surface area and improve dust holding capacity when in use.

[0034] Further, the second filter element 83 is a molecular sieve filter element.

[0035] In the above embodiment, the molecular sieve filter element of the application can preferably be a 3A type molecular sieve. The pore size of this type of molecular sieve is 3 angstroms, which is exactly the diameter of a water molecule, so it can effectively adsorb water molecules. When the 3A molecular sieve comes into contact with water, the polar groups of the water molecules quickly interact with the polar surface of the molecular sieve, thereby achieving the effect of adsorbing water molecules in the internal channels of the molecular sieve. The particle diameter of carbon dioxide is 3.3 angstroms, which is significantly larger than the internal channels of the 3A type molecular sieve, so it does not enter the internal channels of the molecular sieve, but passes between the molecular sieve particles. In this way, the second filter element 83 of the application can cooperate with the HEPA filter in the first filter element 82 to achieve dual control of humidity and particulate matter in the air to be detected.

[0036] Further, as shown in Figures 2-4 The detection chamber 6 is provided with a check valve 10 on the side wall opposite the mounting frame 81 along the length direction of the partition plate 2.

[0037] In the above embodiment, the valve cover of the check valve 10 is opened towards the air suction unit 7, and in the normal state, the check valve 10 is closed on the partition plate 2, so that the detection chamber 6 can be closed when not in use to prevent impurities in the environment from entering the inside and causing unnecessary pollution.

[0038] Further, as shown in Figure 2 and Figure 4 , the air suction unit 7 comprises an axial flow fan 71 installed on the side wall of the outer box body 1 adjacent to the side, and the center of the axial flow fan 71 is opposite to the center of the check valve 10. A protective net 72 is fixedly installed on the outer box body 1 corresponding to the axial flow fan 71.

[0039] In the above embodiment, the axial flow fan 71 can generate suction in the outer box body 1 during operation to guide the air in the environment from the air inlet cylinder 9 to pass through the filter unit 8 and the detection chamber 6 in turn along the horizontal direction. The protective net 72 installed on the outer box body 1 corresponding to the axial flow fan 71 can prevent the technician from being injured during operation.

[0040] Further, as shown in Figures 2-4 , a inclined support plate 11 is arranged on the side away from the axial flow fan 71 in the space above the partition plate 2 in the outer box body 1.

[0041] In the above embodiment, when the air to be detected flows into the outer box body 1 from the air inlet cylinder 9, the flow direction of the air is perpendicular to the arrangement direction of the filter unit 8, the detection chamber 6 and the axial flow fan 71, so that local turbulence and vortex are easily formed during air flow, reducing the air flow transmission efficiency. Therefore, the inclined support plate 11 is arranged below the air inlet cylinder 9 according to the above manner to reduce the local resistance when the air flows to the detection chamber 6 and improve the air flow transmission efficiency.

[0042] Further, as shown in Figures 1-4 , a rainproof plate 12 is arranged at intervals on the top of the air inlet cylinder 9, and the rainproof plate 12 is fixedly connected to the top of the air inlet cylinder 9 by a plurality of supporting legs.

[0043] In the above embodiment, when it rains outside, the rainproof plate 12 can effectively block rainwater from invading the inside of the equipment.

[0044] Further, as shown in Figure 2 and Figure 3 , an inwardly protruding step is arranged on the inside of the upper end of the air inlet cylinder 9, and a metal filter screen 13 is arranged on the step inside the air inlet cylinder 9.

[0045] In the above embodiments, when air is sucked into the outer box body 1, the metal filter screen 13 arranged in the upper port of the air inlet cylinder 9 can block some large-size impurities in the air (such as some dry leaves, plastic bag fragments, etc.). Since the metal filter screen 13 is located at the upper port of the air inlet cylinder 9, it is more convenient for technicians to clean.

[0046] The implementation principle of the present embodiment is that when a technician uses the detection device of the present application to detect the carbon emission of the surrounding air in a specified area, the technician can first start the axial flow fan 71 in the air suction unit 7 to guide the air in the external environment to enter the outer box body 1 along the air inlet cylinder 9. Since the detection device may have air from other places remaining in the detection chamber 6 when it is first used, in order to avoid the influence of the remaining air on the detection effect, the detection element 3 should not be started for detection at first. The axial flow fan 71 is used to continuously introduce the air in the area to be detected into the device for a certain period of time to ensure that the air in the detection chamber 6 is completely replaced by the air in the area to be detected. Then the detection element 3 in the outer box body 1 can be started to analyze the air flowing through the detection chamber 6, so as to obtain the actual carbon emission data on site.

[0047] The detection chamber 6 of the detection element 3 of the present application for detecting air is located between the air suction unit 7 and the filtering unit 8, so that the air flows through the filtering unit 8 and the detection chamber 6 in sequence when flowing to the air suction unit 7. The installation frame 81 in the filtering unit 8 has a first filter element 82 and a second filter element 83 arranged side by side therein, and the first filter element 82 is located on the side of the second filter element 83 away from the detection chamber 6. In this way, the air will first pass through the first filter element 82 and the second filter element 83 in sequence before entering the detection chamber 6. The dust and aerosol inside the air will be removed when the air passes through the first filter element 82. The air will be further dehumidified when it continues to pass through the second filter element 83. After the treatment of the first filter element 82 and the second filter element 83, it can be ensured that the detection element 3 will not be disturbed by water vapor, dust, and aerogel in the air when detecting the air entering the detection chamber 6. Accordingly, the precision of the carbon emission related data detected will be effectively improved.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for some or all of the technical features. Such modifications or replacements do not change the essence of the corresponding technical solutions, which still fall within the scope of the technical solutions of the embodiments of the present application.
