EXPERIMENTAL STUDY ON PARTICLE DEPOSITION IN PIPELINES IN A FRESH AIR SYSTEM

ABSTRACT
A semi-empirical formula was recommended to analyze the deposition law of atmospheric particles in pipelines in fresh air systems, where the sizes of particles, inlet velocity, and the air temperature, humidity on the deposition of particulate matters were considered. The results showed when the particle sizes were less than 1.0 μm, the deposition rate was decreased from the increased in particle sizes. When the particle sizes were larger than 1.0 μm, the deposition rate was in-creased from the increased in particle sizes. A higher inlet velocity resulted in a greater deposition rate. High humidity or low temperature would also lead to a high deposition rate of dust. The results given in this paper are helpful for optimization of the fresh air system.
