Problems solved by technology
For point sources, such as emissions from industrial chimneys, the conventional measurement system used is the continuous emission measurement system (CEMS), which has a plug-in flue spectrum measurement method, or an extraction sampling dilution optical measurement (ultraviolet fluorescence method, chemiluminescence method), but CEMS systems are relatively bulky and expensive; there are also electrochemical methods for measurement, but their life is short and continuous measurement cannot be achieved, and they are generally used for periodic testing purposes
For multi-point sources and unorganized emission sources, the various pollution emissions contained in them are complex and there are many unknown factors. Usually, the pollution source survey and statistics method is used to obtain the total emission. However, the source inventory investigation is time-consuming and laborious, especially With the rapid development of my country's economy and rapid changes, timely updating of source data seems powerless

The invention discloses a multi-component gas analyzer which comprises a sun tracker 1, a spectrograph 2, a GPS positioning system 4, a meteorological instrument 5 and a computer 3. Sunlight serves asa light source, the height and the direction of the sun are tracked through the sun tracker, it is guaranteed that the light source is transmitted into the spectrograph all the time, and real-time and rapid measurement and analysis of multi-component gas in a polluted area are achieved. The multi-component gas analyzer provided by the invention has the advantages of being light in structure, relatively low in manufacturing cost and convenient to move, and meanwhile, multi-component, low-concentration and long-distance measurement can be carried out.
Description
technical field [0001] The invention relates to an open multi-component gas monitoring device, in particular to a Michelson-based multi-component gas analysis device. Background technique [0002] The continuous automatic monitoring of atmospheric multi-component pollutants and their temporal and spatial distribution is one of the urgent problems to be solved in the field of atmospheric environmental monitoring research in my country. Developed countries have established a fairly complete monitoring technology and method system in related fields, forming a ground-based Data, point source emissions, and a small amount of conventional monitoring components are developing towards three-dimensional, non-point source, and multi-component continuous automatic monitoring technologies. The Environmental Technology Verification Program (ETV) developed by the US Environmental Protection Agency (EPA) aims to promote the innovation and development of environmental science and technology ...
