The Design Of Portable Multifunction Flue Gas

With the rapid development of economy, heavy industry, transport and the rising of our living standard, a large amount of harmful substances discharge into the atmosphere. The air of normal is changed by the harmful substances, the final result of air quality is deteriorated. The health problem caused by air pollution has been attached great importance to governments and people.The flue gas release of industrial burning process is the source of atmospheric pollution of the city. Flue gas detection is the essential project to the atmospheric environment testing. In order to improve the combustion efficiency, save energy, reduce air pollution, control the fuel and air ratio in the burning process, we must be effective measuring the content of various components in flue gas. Through flue gas monitoring, we can identify the key sources of pollution, at the same time monitoring the pollution sources real-time. However, the past flue gas monitoring, from collecting samples to analysis results should go through more than one link, not only workload is big, but also easy cause samples defiled and make data distortion. Therefore, using new technology equipment to improve the monitoring efficiency and the data analysis accuracy is very necessary. This topic according to actual demand, design a kind of portable multifunctional flue gas analyzer.Portable multifunctional flue gas analyzer used for test the various atmospheric pollutants release of the gas flue and at the same time test the content, pressure, temperature of the gas. The measured parameters and the real-time displayed by LCD. Storage measurement data through the mian control chip. Consequently, reflect the gas characteristics in particular environment comprehensively. The system hardware keep the core of LPC2214, responsible for the entire system control and design, part of the software writing by modular thought of programs.Portable multifunction gas analyzer has the advantage of direct display, simple operation, convenient carrying and data processing capability. In addition to used for industrial gas analysis, it can also be extended to food analysis, biological and other medical applications. It is a new type of portable energy saving analysis instrument. With slight modification on this foundation, it can be used for online monitoring environment.
