Description

Technical Field

[0001] The invention belongs to the technical field of gas detection, and in particular relates to a mobile greenhouse gas emission detection machine. Background Art

[0002] Greenhouse gases refer to some gases in the atmosphere that can absorb solar radiation reflected by the ground and re-emit radiation, such as water vapor, carbon dioxide, and most refrigerants. Their function is to make the earth's surface warmer, similar to the role of greenhouses in intercepting solar radiation and heating the air in the greenhouse. This effect of greenhouse gases making the earth warmer is called the "greenhouse effect". Greenhouse gases refer to gases in the atmosphere that easily absorb infrared rays. The main greenhouse gases in the atmosphere are carbon dioxide (CO2) and methane (CH4). Among them, carbon dioxide is considered to be the most effective greenhouse gas, accounting for 63% of the total greenhouse gases, and in recent decades, human industrial activities have increased carbon dioxide emissions, resulting in excessive accumulation of greenhouse gases in the atmosphere, exacerbating the greenhouse effect. Methane accounts for 17% of the total greenhouse gases, and its greenhouse effect capacity is about 25 times that of carbon dioxide. A large amount of methane on the earth exists in the form of hydrates in the permafrost layer on the seabed or in the cold polar regions. As the temperature of the earth rises, the permafrost in the cold regions melts, causing methane to be released, thus entering the atmosphere and exacerbating global warming.

[0003] The greenhouse effect refers to the insulation effect formed by the lack of heat exchange between a closed space that transmits sunlight and the outside world. That is, the short-wave radiation from the sun can penetrate the atmosphere and penetrate the ground, while the long-wave radiation emitted after the ground warms up is absorbed by substances such as carbon dioxide in the atmosphere, thus producing the effect of atmospheric warming. Greenhouse gases may not only cause global warming, but also have an impact on various organisms in the entire earth's ecosystem.

[0004] At present, it is usually necessary to carry detection instruments to different regions to monitor greenhouse gases in the local atmospheric environment. During this period, the staff need to carry the instruments for a long time and observe and analyze the displayed data of the instruments, which will increase the labor intensity of the staff and is inconvenient to operate.
