The gas in the flue gas flue is not compressed, so that the calculated flow of the section of the sampling point obtained by taking the sampling point as a reference value can be obtained by a flue gas flow velocity measuring device arranged at the sampler. Through the comparison of the 2 flows, the velocity field compensation coefficient of the point can be obtained, and accurate data of pollutants can be obtained through compensation.

The invention measures the temperature of the flue gas and the sample gas, calculates the theoretical air extraction amount after temperature compensation, obtains the theoretical sample gas flow speed S2 during constant-speed sampling, adjusts the extraction power source, obtains the feedback extraction flue gas flow speed S, can ensure that the S is more than, less than or equal to the S2 to realize speed control sampling with temperature compensation, and ensures that the particulate matter and gas monitor accurately measures the particulate matter and gas content in the flue gas through the measuring chamber. However, the integrated sampler can be exposed to the smoke again for a long time in the sampling process, so that the corrosive gas in the smoke can corrode the integrated sampler, and the integrated sampler is directly damaged or the service life of the integrated sampler is shortened. In order to solve the problems, the invention provides a flue gas acquisition and measurement system with non-uniform velocity field compensation.
