EFFECT OF PIPES MATERIALS ON PARTICULATE MATTERS DEPOSITION IN FRESH AIR FILTRATION SYSTEMS: A CASE STUDY

ABSTRACT
With the widespread popularity of fresh air filtration systems, the pipes materials have become one of the important parameters that affect the overall performances of the fresh air systems. In this paper, an experimental study on the deposition of particulate matters on two commonly used pipes materials (PVC and PE) in the market was tested, and conducted an in-depth analysis of its influencing factors. The results showed that the deposition rates of particulate matters in the PVC pipe increased with the increased of the inlet velocity, and the deposition rate reached the maximum at the velocity was 4.0 m/s. While the deposition rates of particulate matters in the PE pipe were increased first and then decreased with the increased of the inlet velocity, and the deposition rates reached the maximum at the velocity was 3.5 m/s. The PM values deposition rates showed the pipe systems of PE were higher than that of PVC. With the increased of the particle sizes, the tends of deposition rates increased gradually. There were big differences in the deposition rates of particle sizes of less than 1.0 μm, and the largest difference was 0.615 μm, with 8.44%. Therefore, reasonable pipe-line materials should be selected comprehensively according to actual need in the process of pipe-line installation and use. It would provide a useful reference value for the selection of pipe-line materials in the fresh air filtration systems in the post-epidemic era.
