Comprehensive test apparatus for coal or biomass combustion flue gas pollutants, and method thereof

Abstract

The present invention relates to a comprehensive test apparatus for coal or biomass combustion flue gas pollutants, and a method thereof. The comprehensive test apparatus comprises a combustion-supporting gas supply and regulation system, a high-temperature tube type furnace system, a pipeline system and a flue gas pollutant analysis system, wherein the combustion-supporting gas supply and regulation system is connected with the high-temperature tube type furnace system through a high temperature resistance detachable flange on the front end of the pipeline system, and the high-temperature tube type furnace system is connected with the flue gas pollutant analysis system through a high temperature resistance detachable flange on the rear end of the pipeline system, such that the integrated test on the discharge characteristics of the gas-state pollutants and the particle pollutants during the coal combustion process, the biomass combustion process or the coal and biomass mixed combustion process can be simultaneously achieved. With the apparatus and the method of the present invention, the discharge characteristics of various pollutants in the coal or biomass combustion flue gas can be completely and comprehensively measured in one time, the advantages of economy and efficiency are provided, the error caused by the multiple measurements can be reduced, and the apparatus and the method can be widely used in energy sources, environments, chemical industry and other science and engineering fields.

Description

technical field [0001] The invention relates to a monitoring and control device for combustion pollutant discharge, and relates to a comprehensive testing device and method for coal or biomass combustion flue gas pollutants. Background technique [0002] According to the Bulletin on the State of the Environment in China from 1989 to 2013, the air pollution caused by industrial sources including fuel combustion is the main source of my country's atmosphere, of which SO x , NO x , Particulate matter (PM) and so on are the main air pollutants, which have caused great harm to the natural environment and human health. In view of the contribution of air pollution from combustion sources to the overall air environment quality, emissions and pollution, the emission, monitoring and control of combustion pollutants are becoming increasingly urgent. From the perspective of macro policies, regulations and standard systems, in order to improve the quality of the air environment, preven...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive testing device and method for coal or biomass combustion flue gas pollutants in view of the problems in the above background technology, which can solve the incompleteness and asynchrony of single pollutant research and multiple The experiment caused problems such as long experiment period, large investment in manpower and material resources, and out-of-synchronization of the experimental values ​​of different types of pollutants measured multiple times. The gas switching required by the device is convenient, and the online PM 10 / PM 2.5 The addition of water cooling and inert gas dilution system in front of the particle analyzer effectively expands the monitoring range of the particle analyzer, making it more widely used in the monitoring of pollutants from different fuel combustion
