Abstract
A tube-in-tube inline solids conditioner and pre-wetter. The conditioner has three concentric tubes. A first ingredient is fed into an inner tube. A second ingredient is fed into an outer tube. The middle tube has a flared nozzle to form a tear drop flow with the second ingredient that surrounds the first ingredient. A vacuum chamber is formed between the middle tube and the inner tube. The cocoon and the vacuum prevent the formation of condensation inside the conditioner. The conditioner combines the two ingredients into a mixture that is pumpable.
Claims20
An inline static mixer assembly including a tube-in-tube configuration for conditioning and pre-wetting solids for discharge into a pump or a tank comprising:
- an inner tubular housing having an inlet and an outlet:
- a middle tubular housing concentrically surrounding the inner tubular housing;
- an annular vacuum chamber defined between an outer surface of the inner tubular housing and an inner surface of the middle tubular housing;
- a vacuum port extending through the middle tubular housing in fluid communication with the annular vacuum chamber;
- an outer tubular housing concentrically surrounding the middle tubular housing;
- a tangential liquid inlet connected to the outer tubular housing;
- wherein the middle tubular housing terminates in a flared annular nozzle concentrically surrounding the outlet of the inner tubular housing;
- and
- wherein the outer tubular housing comprises a surge zone portion extending downstream of the flared annular nozzle.
An inline static mixer assembly including a tube-in-tube configuration for conditioning and pre-wetting solids for discharge into a pump or a tank comprising:
- an inner tubular housing having a vertically oriented inlet and an outlet:
- a middle tubular housing concentrically surrounding the inner tubular housing;
- an annular vacuum chamber defined by a space separating an outer surface of the inner tubular housing and an inner surface of the middle tubular housing;
- wherein the middle tubular housing comprises a tapered portion in contact with the outer surface of the inner tubular housing, the tapered portion sealing a downstream end of the annular vacuum chamber;
- an outer tubular housing concentrically surrounding the middle tubular housing;
- a tangential liquid inlet connected to the outer tubular housing and positioned upstream of the tapered portion of the middle tubular housing;
- wherein the middle tubular housing terminates in a flared annular nozzle extending downstream from the tapered portion;
- wherein the flared annular nozzle and the outlet of the inner tubular housing define an annular discharge gap bounded by an inner surface of the flared annular nozzle and an outer surface of the outlet of the inner tubular housing;
- and
- wherein the outer tubular housing comprises a surge zone portion extending downstream of the flared annular nozzle.
An inline static mixer assembly including a tube-in-tube configuration for conditioning and pre-wetting solids for discharge into a pump or a tank comprising:
- an inner tubular housing extending along a central longitudinal axis;
- a middle tubular housing concentrically disposed around the inner tubular housing;
- an outer tubular housing concentrically disposed around the middle tubular housing;
- a clamp mechanism securing an upstream end of the inner tubular housing, an upstream end of the middle tubular housing, and an upstream end of the outer tubular housing in a fixed concentric arrangement;
- a static annular vacuum chamber defined by a volume separating an outer surface of the inner tubular housing and an inner surface of the middle tubular housing;
- wherein the middle tubular housing comprises a tapered portion downstream of the clamp mechanism that directly contacts the outer surface of the inner tubular housing to seal a lower end of the static annular vacuum chamber;
- a tangential liquid inlet connected to the outer tubular housing at a position axially located between the clamp mechanism and the tapered portion;
- wherein the middle tubular housing terminates in a flared annular nozzle extending downstream from the tapered portion;
- and
- wherein the flared annular nozzle and an outlet of the inner tubular housing define an annular discharge gap bounded by an inner surface of the flared annular nozzle and an outer surface of the outlet of the inner tubular housing.
