Abstract

The invention discloses a device for obtaining a soot breaking characteristic in a combustion process. The device comprises a computer control system, an aerosol generator, a thermal processor, a gasmixer, a particle size spectrometer, a capillary sampling system, a premixing combustor, a displacement table and a constant-temperature water tank; the premixing combustor comprises a coil pipe, a first metal sintering plate, a center steel pipe and a second metal sintering plate; an air inlet pore of the second metal sintering plate is connected to an argon cylinder; the air inlet pore of the first metal sintering plate is connected to the outlet end of the gas mixer; the gas mixer comprises two air inlet ends, wherein one inlet end is connected to the outlet end of the aerosol generator, abypass B in parallel with the pipeline A, the thermal processor is arranged on the bypass B and the other air inlet end is connected to an air inlet main pipeline connected with a methane gas cylinderand an oxygen cylinder; and a flow meter is arranged on each gas pipeline. According to the device for obtaining a soot breaking characteristic in a combustion process, the research of breaking characteristic of soot in the combustion process can be realized, thereby providing a theoretical basis for further controlling the emission of soot in the combustion process.

Description

technical field [0001] The invention relates to a device and method for studying the crushing characteristics of soot particles, in particular to a device and method capable of obtaining the crushing characteristics of soot particles in the combustion process. Background technique [0002] As one of the important indicators of soot particulate matter emission, particle size and number concentration are closely related to human health and atmospheric environment. Therefore, while the mass emission of particulate matter is controlled by the automobile engine, the requirements for particle number concentration emission are becoming increasingly strict, and the crushing characteristics of soot particles in the combustion process are important reasons that affect the particle size and number concentration of soot particles. Due to the oxidation-induced effect of soot particle agglomerates and individual particles of soot particles in the combustion process, the joints of soot par...
