Smoke monitoring system and smoke monitoring method

Abstract

The invention provides a smoke monitoring system and a smoke monitoring method. The smoke monitoring system comprises a smoke acquisition device, a terahertz monitoring device and a data receiving processing device; the smoke acquisition device is used for acquiring smoke samples; the terahertz monitoring device is connected with the smoke acquisition device and is used for detecting the smoke samples acquired by the smoke acquisition device, obtaining characteristic mark peaks of smoke components in the smoke samples and outputting the characteristic mark peaks of smoke components in the smoke samples; the data receiving processing device is connected with the terahertz monitoring device and is used for analyzing and comparing the received characteristic mark peaks of the smoke components and outputting the determined smoke components and the contents of the smoke components. The smoke monitoring system has a simple structure, the high result accuracy and the good instrument stability when being used for measuring smoke, and the smoke monitoring system can monitor the smoke, effectively control the smoke and reduce the air pollution before the smoke is exhausted into atmosphere.

Description

technical field [0001] The present invention relates to the field of environmental monitoring, in particular to a flue gas monitoring system and detection method, in particular to a flue gas monitoring system and method based on terahertz time-domain spectroscopy technology. Background technique [0002] Flue gas is a mixture of gas and soot. The composition of flue gas is very complex, including water vapor, SO 2 , N 2 , O 2 , CO, CO 2 , hydrocarbons and nitrogen oxides, etc., and smoke includes fuel ash, coal particles, oil droplets, and high-temperature cracking products. Therefore, the pollution of flue gas to the environment is the compound pollution of various poisons. Smoke not only pollutes the atmosphere, but also harms human health. In order to ensure the cleanliness of human living environment, the state clearly requires that flue gas must be effectively treated before it is discharged into the atmosphere. [0003] Before the staff can process the flue gas, ...

Problems solved by technology

However, due to the complex chemical composition of combustion exhaust gas, in addition to chemical analysis methods, many new detection methods and technologies have been continuously applied to the detection of flue gas.

However, the existing analysis methods are more complex and prone to error
