Title:
AIR TRANSPORTING METHOD AND AIR TRANSPORTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/075959
Kind Code:
A1
Abstract:
The present invention provides a novel air transporting method and air transporting system for a suction-type air transporting system that can maintain the pipe diameter of an inner pipe of a transporting pipe made as a double pipe structure. The present invention uses a double pipe structure transporting pipe (5) comprising a flexible inner pipe (51) that communicates with the interior of an air transporting device (2), and an outer pipe (52) that isolates the inner pipe (51) from the outside air. In addition, when a granular material is transported by suction, the inner pipe (51) pipe diameter is maintained by way of reducing the internal pressure of a gap space (S) formed by the inner pipe (51) and the outer pipe (52) to below the internal pressure inside the inner pipe (51).
