Description

Technical Field

[0001] The present invention belongs to the technical field of gas detection, and in particular relates to a sewage treatment greenhouse gas detection device and a detection method thereof. Background Art

[0002] Greenhouse gases refer to gases in the atmosphere that absorb longwave radiation reflected from the ground and re-emit it, such as water vapor, carbon dioxide, and most refrigerants. Their effect is to warm the Earth's surface, similar to how a greenhouse traps solar radiation and heats the air within. This warming effect is known as the greenhouse effect. Water surface greenhouse gas detection devices are used in sewage treatment plants to monitor and treat greenhouse gases on the surface of sewage tanks.

[0003] The detection range of existing water surface greenhouse gas detection devices during use is usually relatively fixed, which is not convenient for absorbing and detecting greenhouse gases at different heights, nor is it convenient for absorbing and detecting greenhouse gases at different positions. Moreover, existing water surface greenhouse gas detection devices usually do not have a filtering function during use, and the gas may contain dust or dust particles that will affect the gas detection effect. Therefore, a municipal sewage treatment greenhouse gas detection device is needed.
