Problems solved by technology

[0005] The gas sensor of the continuous emission monitoring system (CEMS) of fixed pollution sources has the problem of measurement range. For sensors with large range, the detection accuracy is low and the error of measurement results is large; for sensors with small range, the detection accuracy is high. However, when the gas concentration exceeds its range, its accurate value cannot be determined

Abstract

The invention discloses an automatic monitoring method and system for flue gas pollutants. The automatic monitoring method and system are used for continuous and real-time tracking and measurement ofpollutants in flue gas discharged from fixed pollution sources. A plurality of sampling pipelines are arranged at a flue gas collection position; when the concentration of the pollutant exceeds a range, by control of an inlet of each sampling pipeline, the flue gas pollutants exceeding the range can be accurately detected, thereby providing accurate and effective automatic monitoring data timely and completely.

Description

technical field [0001] The invention relates to an automatic analysis system, in particular to an automatic monitoring and analysis method for smoke pollutants in the field of environmental protection detection and a detection and monitoring system. Background technique [0002] The sustained and rapid development of the national economy has brought about a continuous increase in energy consumption, and environmental pollution has increasingly become a hot issue of national concern. Among them, the degree of air pollution is particularly serious. In recent years, many cities and regions in China have experienced smog weather, which has brought great harm to residents' life and travel. The large amount of coal-burning smoke is one of the reasons for the formation of smog. my country's energy consumption is dominated by coal combustion, and it is the largest coal producer and consumer in the world. During the coal combustion process, a large number of pollutants that seriously...
