Description
Bypass pneumatic conveying systems provide a passive capability to reduce attrition and abrasion in the process of conveying fragile particulate material and erosive particulate solids. These systems can also provide a dense phase capability to non-dense phase capable bulk materials. In both cases, the conveying velocities are much lower and therefore less particle degradation, lower pipeline wear and lower power consumption is usually achieved. There are two basic types of bypass systems; external and internal, with the main design aspects being the bypass pipe diameter and the distance between the bypass line openings (flute spacing). However, a clear design procedure is limited. Therefore, this paper proposes a simple design protocol for the bypass pipeline for both external and internal bypass systems. The bypass pipeline diameter design protocol is based on an air mass flow rate balance approach between the main pipe and the bypass pipe, while the flute spacing design protocol is based on the pressure drop across a dense packed particulate bed.
