Description

Technical Field

[0001] The utility model relates to the technical field of dust detection, and more specifically, it relates to a light extinction device which is convenient to install. Background Technique

[0002] Dust detection is a crucial task, mainly used to evaluate the content, composition and characteristics of dust in the air. In industrial production environments such as mines, cement plants, foundries, etc., excessive dust will pose a serious threat to the health of workers, possibly leading to respiratory diseases, lung diseases and even cancer; in environmental monitoring, dust detection helps to understand the pollution degree of particulate matter in the atmosphere and provides a basis for formulating environmental protection policies and measures.

[0003] At present, the light scattering method for detecting dust concentration is fast and can monitor in real time online. The principle of the light scattering method for detecting dust concentration is that when light irradiates dust particles, scattering will occur, and the dust concentration is deduced by measuring the intensity of the scattered light.

[0004] However, in the light scattering method for detecting dust concentration, natural light will enter the detection device along with the dust airflow, and the natural light will affect the detection result. Therefore, a light extinction device which is convenient to install is proposed to improve the existing problems. Content of the Utility Model
