Abstract

The invention discloses a filter paper type gas engine flue gas automatic sampling and detecting device and a detecting method. The device comprises a filter paper belt conveying assembly, a flue gascollecting assembly, reflectometer assemblyies and a lifting structure which are installed on a support. The filter paper belt conveying assembly comprises a filter paper belt which is movably placedon a filter paper belt bottom plate; the flue gas collecting assembly comprises a first flue gas collecting mechanism installed on the side, away from a filter paper belt bottom plate, of the filter paper belt through the support, and a second flue gas collecting mechanism installed on the side, away from the filter paper belt, of the filter paper belt bottom plate. The reflectometer assemblies are mounted on the two sides of the first flue gas collection mechanism and act on the filter paper belt; the lifting structure moves to drive the filter paper belt bottom plate to lift so as to changethe distance between the filter paper belt and the flue gas collection assembly. The invention relates to a device capable of realizing continuous and automatic sampling and detection of flue gas of agas engine and electronic storage and detection data traceability of a sampled sample, and can be expanded to automatic sampling and detection of flue gas in flue gas index measurement of a ground gas turbine.

Description

technical field [0001] The invention relates to an automatic sampling and detection device for flue gas in the measurement of smoke index, in particular to a device that can realize continuous automatic sampling and detection of exhaust gas from aviation gas engines, and electronically store and detect data traceable for sampling samples. Extended to the automatic sampling and detection of flue gas in the measurement of smoke index of ground gas turbines. Background technique [0002] As early as the 1960s, engine gas analysis technology had been applied in the development of aero-engines in my country, and played an important role in the detection of engine exhaust. How to evaluate the performance of the engine through the detection of the engine exhaust, and then develop a more efficient engine, has become a topic worthy of further study. [0003] At present, the measurement of engine smoke index is based on the principle of reflectivity measurement, and the sampling of s...
