中文摘要:针对现有的稀释通道多级采样装置存在稀释比小、停留时间短和便携性能差等问题,根据生物质成型燃料燃烧排放高温烟气中的大气颗粒物数量和质量分布特点,采用二级稀释、反馈调节和射流的原理,设计了生物质固定燃烧源烟气稀释采样装置。该装置由采样枪、一级稀释系统、二级稀释系统、洁净空气发生系统、撞击采样装置等部分组成。装置加工完成后,采用木质成型燃料开展颗粒物采样试验,试验结果表明,该装置能够模拟固定燃烧源排放烟气进入大气环境中的稀释冷凝过程,稀释比达30,停留时间90s,试验采集得到8种不同粒径级别的大气颗粒物,其中粒径在0.4~1.1μm之间颗粒物占总采集颗粒物的55.5%~68.1%。研究发现采样装置对空气动力学直径在1.1μm以下的大气颗粒物有较好的采样效果。

Abstract:Aiming at solving the shortcomings of low dilution ratio, short residence time and bad portability of the existing dilution channel sampler, the flue gas dilution sampler for biomass fixed combustion source was developed by using the principle of multistage dilution and jet, according to numbers of atmospheric particulates and characteristics of mass distribution in high temperature flue gas. The sampler consists of five parts: sampling gun, first level dilution system, second level dilution system, clean air making system, impact sampling device and display control system. The proposed sampler has good air tightness, high dilution ratio, stable heat preservation performance and good control precision. The biomass fixed combustion source of flue gas dilution sampler was applied on the wood molding testing. Test results show that the proposed device could simulate the dilution and condensation process of combustion source flue gas which emissions into the atmosphere environment with dilution ratio of 30 and residence time of 90s. The atmospheric particulates in eight different particle sizes were obtained, in which the mass of particle size of 0.4~1.1μm took 55.5%~68.1% of the total mass of atmospheric particulates. The study found that the proposed sampler has a good effect on the atmospheric particulates with diameter less than 1.1μm.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
