Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas detection, and more specifically, to an exhaust gas detection device. Background Art

[0002] Differences in the physical and chemical properties of exhaust gas components: The physical and chemical properties of exhaust gas components can also lead to stratification. Some heavier particles or high-boiling organic exhaust gas components tend to settle in the lower layer under the action of gravity. For example, in a painting workshop, larger particles in the paint spray may fall near the ground due to gravity before they are completely dry, making the concentration of particles in the lower exhaust gas relatively high. Some light volatile organic compounds (VOCs) may rise to the upper space with the hot air flow.

However, in actual use, the differences in temperature and the physical and chemical properties of the exhaust gas components lead to easy stratification, resulting in insufficient detection.
