Embodiment Construction

[0041] To illustrate an embodiment of the invention, figure 1 A schematic diagram of a granulation plant 10 designed for slag granulation in a blast furnace plant (which is not shown) is shown. In general, the apparatus 10 is thus used to granulate a stream of molten blast furnace slag by quenching it with one or more jets 12 of relatively cool granulation water. like figure 1 As shown, molten slag stream 14 , which inevitably flows out of the blast furnace together with pig iron, falls from hot melt launder end 16 into granulation tank 18 . During operation, a jet of granulated water 12 impinges on molten slag 14 falling from the end 16 of the hot runner, the jet of granulated water being pumped by one or more parallel high pressure pumps (not shown) via A water injection device 20 (also commonly referred to as a "spray box") is supplied by a supply pipe 22 . A suitable configuration of the water injection device 20 is eg described in patent application WO2004 / 048617. I...

Abstract

The invention relates to a granulation plant (10) for granulation of molten material produced in a metallurgical plant. The apparatus comprises: a water injection device (20) for injecting granulation water into the molten material stream (14) to granulate the molten material; a granulation tank (18) for collecting the granulation water and material. The apparatus also includes a vapor collection hood having a vent for venting vapor from the hood, condensing the vapor, and venting the condensed vapor to the atmosphere.

Description

technical field [0001] The present invention generally relates to a granulation plant for molten material, in particular for metallurgical smelts such as blast furnace slag. The present invention more particularly relates to an improved vapor condensing system for use in such equipment. Background technique [0002] attached figure 2 An example of a modern granulation plant of this type, especially for molten blast furnace slag, is shown in , with figure 2 is the April 2005 issue of Iron & Steel Technology entitled " Slag granulation system-Environmental process control( Slag Granulation System - Environmental Process Control)" article. As in figure 2 As shown, equipment of this type typically includes a water injection device 2 (also referred to as a water injection box) for injecting granulated water into the flow of molten material (eg slag) received via the launder end 1 middle. Granulation of the molten material is thereby achieved. The plant also has a granula...
