RESEARCH ON PRODUCTION AND ASSESSMENT OF PRESSURE LOSS OF PM2.5 PARTICLE FILTER MADE FROM STEEL CHIPS APPLIED IN MOTORCYCLE

Abstract

Pollution of PM2.5 particles is more and more serious; vehicles contribute
greatly to patticles pollution in the air. This paper presents a solution to fabricate
and investigate the structural characteristics, morphology, and pressure loss of
PM2.5 particulate filter made from steel chips applied to motorcycles. Press
equipment, XRD structure analyzer, electron microscope, differential pressure
measuring device are used to fabricate and evaluate the structural properties,
shape, and pressure loss of the filter chip sample. The results showed that the steel
structure was observed, there was no phase transition during pressing. When the
press pressure is raised, the filter sample's pores and chip layers tend to align more
closely. However, when the pressure is raised to 600bar, chip fibers start to shatter
and fracture. The results also demonstrate that the pressure loss of the filter chips is
more strained as the press pressure increases; at press pressure of 500bar filter chip
sample exhibits the same pressure loss as the commercial filter.
