Continuous flue gas emission monitoring system

Abstract

A continuous flue gas emission monitoring system is disclosed and can be used for on-line monitoring of sulfur dioxide concentration, smoke dust concentration of industrial flue gas and flue gas temperature, flue gas flow velocity and flue gas static pressure, all monitored parameters can be displayed in real time and can be transmitted to a local environmental monitoring center through the internet; the continuous flue gas emission monitoring system achieves real-time, remote and large-amount data acquisition and data transmission and other functions; and the continuous flue gas emission monitoring system has strong adaptability, compact structure, easy installation, stable performance and other characteristics. The continuous flue gas emission monitoring system comprises a stationary pollution source, a gaseous pollutant analysis system, a particle matter analysis system and a gas parameter measurement subsystem; the gaseous pollutant analysis system, the particle matter analysis system and the gas parameter measurement subsystem are connected with the stationary pollution source, the gaseous pollutant analysis system includes a sampler purging means and a gaseous pollutant sampler; the particle matter analysis system comprises a particulate matter measuring instrument, an output of the particulate matter measuring instrument is connected to a data acquisition and control system, and the data acquisition and control system is connected to a data processing and remote communication system.

Description

technical field [0001] The invention belongs to the field of industrial environmental protection, and in particular relates to a continuous monitoring system for flue gas discharge. Background technique [0002] At present, particulate matter and sulfur dioxide released by coal-fired power plants have become the primary pollutants of the atmospheric environment. How to limit the discharge of pollutants is of great significance to environmental protection. The monitoring of industrial flue gas emission in our country has always adopted the conventional method, that is, the sampling head is inserted into the flue to extract samples, and then the samples are analyzed in the laboratory to determine the pollutant content in the flue gas. [0003] This method takes a long time and cannot provide long-term, continuous and systematic test data. Therefore, a more convenient and faster method than manual sampling is needed to accurately determine the pollutants in the flue gas. The ...
