System for pneumatically conveying bulk particulate materials

Abstract

A system for pneumatically conveying bulk particulate materials generally consisting of a material transport line including a first conduit formed of a gas permeable material providing a material flow passageway having an inlet and an outlet, a second conduit formed of a gas impermeable material, encompassing and spaced from the first conduit, and a plurality of partition walls disposed between the conduits and spaced along the lengths thereof, defining a plurality of plenums; a nozzle connectable to a source of gas under pressure, inserted into the passageway for injecting gas under pressure therein to impel material disposed in the passageway toward the outlet thereof; a main gas supply line connectable to a source of gas under pressure having branch lines each communicable with a plenum; and each of the branch lines having a pressure regulating means.
