Problems solved by technology
Dioxins are trace-level substances, and the concentration in flue gas is generally 10 -10 g / m 3 Therefore, it is technically difficult to accurately measure its concentration. At present, most of the detection methods for flue gas pollutants other than dioxins are very mature, but the detection of dioxin emissions from incinerators has not yet been realized. Online rapid detection
This indirect detection method needs to overcome the problems of complex components in the flue gas, uneven concentrations, high moisture content, and complicated sampling flow paths.

The invention discloses a smoke pollutant online alternated concentration release processing method and belongs to the technical field of concentrated samples. The method comprises the steps of debugging a working state; exhausting waste gases in a device pipe; measuring standard gases; and measuring samples. According to the method, two-level absorption is employed; according to a first level, agreat number of substances are absorbed through adoption of large volume sampling cold traps; and according to a second level, focusing is realized through adoption of small volume focusing cold traps. The defect that target substance components of a traditional smoke sampling device are relatively few is overcome. The method is an alternated online concentration release method. Alternated enrichment for the smoke pollutants can be realized, so continuous sampling analysis is realized.
Description
technical field [0001] The invention belongs to the technical field of concentrated samples, and in particular relates to a processing method for online alternate concentration and release of flue gas pollutants. Background technique [0002] At present, the relevant technologies of waste incineration and utilization in my country have been widely used, and will maintain a high-speed development trend in the next 10 years. The discharge of secondary pollutants caused by waste incineration, especially the discharge of dioxins, has attracted more and more attention from the government and the public, and has even become a problem that plagues the entire process of site selection, construction, and operation of many waste incineration power generation projects. Tricky question. [0003] According to the requirements of the "Stockholm Convention on Persistent Organic Pollutants" to reduce the emission of dioxins, various emission sources in my country must effectively achieve t...
