Abstract:
1. A flowable material handling system comprising: a tubular casing; a flow development chamber fixed inside the tubular casing, the flow development chamber comprising an outer barrel inside the tubular casing and an inner barrel inside the tubular casing, the outer barrel having an inlet, an outlet, and a tubular wall extending along a longitudinal axis in a direction from the inlet to the outlet, the inner barrel located inside the outer barrel to define a flow space between the outer barrel and the inner barrel to permit flow of flowable material from the inlet to the outlet of the outer barrel; deflector means for deflecting flowable material inside the casing around the inner barrel; wherein the tubular casing, the flow development chamber and the deflector means are configured and arranged to set up a flow pattern in the flow space such that flowable material flowing into the inlet of the outer barrel will circulate around the inner barrel and traverse the flow space from the inlet to the outlet of the outer barrel; wherein the inlet comprises an opening extending transversely to the longitudinal axis through the tubular wall to the flow space between the outer barrel and the inner barrel; and wherein the deflector means comprises a seating nipple spaced from the inlet opening in a direction of flow of the flowable material and located between the outer barrel and the tubular casing to cause flowable material flowing inside the casing to enter the inlet opening.
