Smoke composite analysis system and method

Abstract

The invention relates to a smoke composite analysis system, which comprises a sampling unit, a flow path switching unit, a control unit and a detection analysis unit, wherein the sampling unit at least comprises a first sampling pipeline and a second sampling pipeline; the flow path switching unit comprises an input pipeline and a moving module; the input pipeline is arranged on the moving module; the flow path switching unit is connected with the sampling unit; the control unit controls the moving module to move so that the input pipeline is selectively communicated with the first sampling pipe and the second sampling pipe; and the detection analysis unit is used for analyzing sample information which is input by the input pipe and acquired by the sampling unit through sampling. The invention also provides a smoke composite analysis method. The smoke composite analysis system and the smoke composite analysis method have the advantages of wide application range, strong expansibility and the like.

Description

technical field [0001] The invention relates to the field of continuous monitoring of flue gas, in particular to a composite analysis system and method for continuous monitoring of flue gas and atmosphere. Background technique [0002] At present, the quality of ambient air is receiving more and more attention, and an important source of ambient air pollution is the emission from stationary pollution sources, and systems for monitoring emissions from stationary pollution sources have been widely popularized. At the same time, in the factory area with fixed pollution sources, there will be many workers working on site. Once the discharge of fixed pollution sources exceeds the standard or leaks, the discharged pollutants will pose a great threat to the personal safety and health of the workers. Therefore, in order to ensure the occupational health of the staff, it is urgent to monitor the ambient air in the workplace. [0003] Moreover, the monitoring of fixed pollution sourc...

Problems solved by technology

[0008] However, for particle monitoring, because constant velocity (equal power) sampling must be guaranteed, the sampling method is more complicated and has higher requirements for pipelines, such as: only rigid metal materials can be used, the diameter of the sampling tube cannot be changed, and the wall of the sampling tube cannot be changed. Smooth, no sharp angles, only smooth bends, etc. These factors make it impossible to directly use conventional devices and methods to switch between pipelines. For example, using three-way valves or baffles and other devices will lead to changes in pipelines. diameter, sharp angle, etc.
