Abstract (en)
The invention relates to a mixing device comprising:- a supply section (200), and- a pipe-in-pipe section (100) comprising:- an outer pipe (110) extending vertically and- an inner pipe (120) having a closed top end and having an outlet for the mixture at a bottom end,wherein the inner pipe (120) is arranged concentrically to the outer pipe (110) inside the outer pipe (110) such that an annular space (130) is formed between the outer pipe (110) and the inner pipe (120), wherein the annular space has a closed top end and a closed bottom end,wherein the inner pipe (120) is provided with at least two inner flow inlets (121, 122) for receiving a flow from the annular space (130) into the inner pipe,wherein the outer pipe (110) is provided with an outer flow inlet (111) for receiving a flow from the supply section (200) into the annular space,the outer flow inlet (111) being provided such that a tangential flow is generated in the annular space (130) during use,wherein the two or more inner flow inlets are provided closer to the top end of the annular space than the outer flow inlet.
