Embodiment Construction

[0038]In order to make the technical means of the present invention and the technical effects that can be achieved more clearly and more completely disclosed, an embodiment is provided hereby, and the following detailed description is given in conjunction with the accompanying drawings:

[0039] (1) Industrial waste gas sample collection: The SOC-XI pollution source sampler is used to collect the industrial waste gas in the odor sampling air bag through the method of instantaneous sampling, and the sampling volume is 10L.

[0040] In this example, 11 representative enterprises (pharmaceutical, chemical, metal, printing and dyeing, feed) were selected, and the industrial waste gas was analyzed by electronic nose technology for different waste gases discharged from a total of 20 detection points selected by each enterprise , to determine the main characteristic signals of each production enterprise's exhaust gas. And carry out digital information processing and comparison on the...

Abstract

The invention provides a method for intelligently identifying industrial waste gas pollution sources, and relates to the technical field of waste gas identification. The method comprises the followingsteps of collecting of an industrial waste gas sample, selecting of proper sample feeding time, collection of electronic nose data, analyzing of principal components in all waste gas, analyzing of principal components in waste gas samples of different industries, determining of a principal component analysis model for intelligent identification or not, analyzing of judgment factors of waste gas samples of different industries, and verification of waste gas of target emission source. The method has the characteristics that the identification accuracy is high, the application range is broad, the operation is simple, and the identification speed is quick.

Description

technical field [0001] The invention relates to the technical field of waste gas identification, in particular to a method for intelligently identifying pollution sources of industrial waste gas. Background technique [0002] In today's era of great social and economic development, while the development of industry has brought progress to human beings, it has also brought many negative impacts to society. Environmental pollution is one of the important ones, and industrial waste gas pollution is an important cause of environmental pollution. factor. Industrial waste gas refers to the general term for harmful gases produced by factories in the process of accelerating industrialization that pose a great threat to the environment and human health. There are many types of industrial waste gas. The main pollutants in the atmosphere can be divided into four categories: sulfur-containing compounds, nitrogen-containing compounds, carbon oxides, and volatile organic compounds. Thes...
