Abstract

Abstract A reaction vessel for reacting together two liquids of different specific gravities, for example molten iron and slag in a steelmaking process, is mounted so that it can be tilted about two horizontal axes at right angles to each other and is provided with two peripheral outlets, one for the lighter liquid, such as slag and the other for the heavier liquid such as molten iron, and these outlets are disposed so that the flow of one liquid through one of them is controlled by tilting the vessel about one axis and the flow of the other liquid through the other outlet so that the two liquids can be run off from the vessel either one at a time or both simultaneously, with the rates of flow of the two liquids being independently controlled in dependence upon the angles of tilt about the two axes.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 52 words
A vessel as claimed in claim 1, further comprising means defining a peripheral inlet for said one liquid and means defining a second peripheral inlet for said second liquid, said first and second inlets and said first and second outlets being so positioned that said liquids flow through said container in countercurrent.
Claim 2
Dependent Claim 52 words
A vessel as claimed in claim 1, further comprising means defining a peripheral inlet for said one liquid and means defining a second peripheral inlet for said second liquid, said first and second inlets and said first and second outlets being so positioned that said liquids flow through said container in crosscurrent.
Claim 3
Dependent Claim 16 words
A vessel as claimed in claim 1, further comprising means for feeding solids to said container.
Claim 4
Dependent Claim 16 words
A vessel as claimed in claim 1, further comprising means for feeding liquids to said container.
Claim 5
Dependent Claim 19 words
A vessel as claimed in claim 1, further comprising means for blowing gas through said liquids in said container.
Claim 6
Dependent Claim 22 words
A vessel as claimed in claim 1, further comprising means for blowing gas onto the surface of said liquid in said container.
Claim 7
Dependent Claim 17 words
A vessel as claimed in claim 1, further comprising means for heating said liquids in said container.
Claim 8
Dependent Claim 62 words
Apparatus comprising a plurality of vessels as claimed in claim 2, means supporting said vessels in cascade formation whereby said one liquid flows through said vessels in sequence under gravity, and lifting means for lifting said second liquid from one of said vessels to another of said vessels whereby said second liquid flows through said vessels in countercurrent to said one liquid.
