Abstract

The invention provides a device for collecting combustion particles and testing smoke components in low-pressure environment. The device comprises a venturi pipeline, a first channel, a second channeland a third channel, one end of the venturi pipeline is a first gas inlet; one end of the first channel is communicated with the other end of the venturi pipeline, the other end of the first channelis a first air outlet, and the first channel is externally connected with a heat release rate tester at the first air outlet; the two ends of the second channel are communicated with the first channel, a gas propeller is arranged at one end of the second channel, a second gas outlet is formed in the other end of the second channel, the second channel is connected with an external gas chromatographat the second gas outlet, and the second channel is connected with a gas cylinder and a pressure relief opening; one end of the third channel is communicated with the venturi pipeline, the other endof the third channel is a second air inlet, and a plurality of layers of detachable filter screens are arranged in the third channel. According to the invention, the problems of collection of smoke particles generated by combustion in a low-pressure environment, heat value test and gas component analysis are solved.

Description

technical field [0001] The invention relates to the technical field of collecting combustion particles of aviation materials and testing smoke components, in particular to a device for collecting combustion particles and testing smoke components in a low-pressure environment. Background technique [0002] In recent years, the demand for civil aviation has increased, the aviation industry has flourished, and new materials have been used in aircraft manufacturing. These new materials often have more excellent features, lighter weight, longer durability, and more reasonable prices. At the same time, its security is also more important. Considering that the cruising altitude of civil aviation passenger aircraft is generally between 8400km and 12500km above sea level, the atmospheric pressure decreases by 100Pa for every 9m increase in altitude, and the passenger aircraft is in a low-pressure environment for a long time during flight. The toxicity of smoke generated after combus...
