PIPE FOR TRANSPORT OF GRANULAR MATTER AND GRANULAR MATTER TRANSPORT METHOD

摘要

The present invention addresses the problem of providing a technology that can use a pipe body having a simple structure to prevent deposition of granular matter during pneumatic transport thereof. The present invention provides a duct having a part formed by a bent duct for transport of granular matter comprising: a transport path wherethrough granular matter being pneumatically transported passes; and an injection path for injecting gas into the transport path from an opening formed in the inner periphery of the bent duct. The injection path injects the gas in the direction that the gas injected from the opening into the transport path forms a vortex along the inner periphery of the bent duct.
