Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention;

[0017] see Figure 1-2 , to illustrate the low-cost multi-path switching differential absorption spectroscopy system for various pollution sources provided by the present invention. The system consists of three parts: a differential absorption path integration pollutant detector, a retroreflector and a two-dimensional or three-dimensional displacement pan-tilt. The detector chassis is equipped with four light source modules (broadband light source) 1, analysis...

Abstract

The invention discloses a multi-path switching differential absorption spectrum system for monitoring various pollution sources, which is characterized by comprising a differential absorption path integral pollutant detector, a reverse reflector and a displacement holder. A case of the detector comprises a light source module, an analysis module, a data processing module, a collimating lens and a convergent lens. The displacement holder can change the pitching and horizontal orientation of the detector. Light emitted by the light source module is collimated, then is emitted to the reverse reflector, and is reflected and returned along the same path. The light is converged by the lens and then enters the analysis module and the data processing module for analysis and processing. The reverse reflector is fixed at a position which is a certain distance away from the instrument but different angles away from the instrument, the path integral concentration of pollutants on different paths can be monitored by rotating the displacement holder, and free switching of multiple paths is realized. The system provided by the invention is high in universality, wide in monitoring range and high in monitoring working efficiency, and can effectively reduce the working intensity of monitoring personnel and reduce accidents.

Description

technical field [0001] The invention relates to the field of air pollution detection, in particular to a low-cost multi-path switching differential absorption spectrum system for monitoring multiple pollution sources. Background technique [0002] In order to deal with the problem of air pollution and protect the health of the people, the demand for monitoring equipment for pollution source gases is increasing. At present, the national control and provincial pollution source enterprises do not have an online monitoring system, but the staff still need to collect and operate the monitoring data on site and bring the monitoring data back to the monitoring station for comparison to draw a test report. This method is time-consuming and labor-intensive, and some pollution sources are toxic. If workers stay in this environment for a long time, they will inevitably damage their own lives and health. In addition, with the continuous and rapid development of my country's economy, ne...
