摘要
Abstract
For the purpose of assuring the quality of coalbed methane and the security of the coalbed methane gathering and transpor-tation system,analysis and precise measurement of the mass concentration of particulate matter in coalbed methane are of greatest importance.In this paper,theoretical and experimental researches are used to determine the mass concentration of particulate matter using the light scattering method.Theoretically,the distribution of scattered light for typical dust particles in coalbed methane was examined in relation to the wavelength of the light source,the size of the particles,and the refractive index of the particles.The ex-periment employed a 532 nm laser as its light source and tested the scattering of common dust particles.This experiment can be uti-lized to determine particle mass concentration with effectiveness in a wide concentration range.Additionally,the ideal scattering an-gle,with an average relative error of the measured mass concentration at only about 5%,is between 90 and 110 degrees.关键词
