Problems solved by technology
[0004] The soot meter currently used adopts the method of multiple weighing tests for the precision calibration of the soot meter. In the pipeline with wind velocity, due to the dynamic pressure generated, the test is not accurate enough. In order to improve the measurement of the filter membrane weight measurement method Accuracy, on the one hand, it is necessary to ensure the correctness of gas metering and filter weighing; on the other hand, it is also necessary to ensure the authenticity and representativeness of the sample when the gas to be measured is sampled, that is, whether the sampling speed can be kept consistent with the flow rate of the smoke gas, reaching For the problem of constant velocity sampling, the uniform flow field with adjustable wind speed provided by the wind tunnel laboratory can just verify the constant velocity suction error of the soot concentration meter. Therefore, it is necessary to design a dynamic soot concentration meter detection system and its verification method

Description
technical field [0001] The invention relates to a detection system of a dynamic smoke concentration meter and a verification method thereof, and belongs to the technical field of measurement and detection equipment. Background technique [0002] Soot is a general term for solid particles suspended in gas formed during the thermal process of oxidation, sublimation, evaporation, and condensation. The smoke and gas tester uses the pitot tube isokinetic sampling gravimetric method to capture particulate matter in the pipeline, and uses qualitative and quantitative determination of harmful gases. It can be used in various boilers in environmental protection, health, labor, safety supervision, military, scientific research, education and other departments. , Determination of the emission concentration / total amount of furnace smoke (gas) and equipment dust removal and desulfurization efficiency. For example, converter flue gas contains a large amount of extremely fine dust. It ca...
