Abstract
The present invention relates to an apparatus for atomizing molten slag and recovering valuable metals, and more particularly to an apparatus for atomizing molten slag and recovering valuable metals, which enables molten slag of a blast furnace or a converter or an electric furnace to be atomized and valuable metals to be recovered.
Claims10
An apparatus for atomizing molten slag and recovering metals, comprising:
- a slag pot;
- a first supplier connected to the slag pot and having an upper portion formed in a hopper shape for supplying molten slag to the slag pot while forming a vortex in the molten slag;
- a second supplier connected to the first supplier for supplying molten slag to the first supplier;
- and
- a third supplier connected to the slag pot for supplying a reducing agent to the slag pot,
- wherein an end of the third supplier is disposed above a space defined between a center of the first supplier and an edge thereof so that the reducing agent can be supplied to the molten slag in the first supplier at the position of the space.

An apparatus for atomizing molten slag and recovering metals, comprising:
- a slag pot;
- a first supplier connected to the slag pot and formed in a hopper shape for supplying molten slag to the slag pot while forming a vortex in the molten slag;
- a second supplier connected to the first supplier for supplying molten slag to the first supplier;
- and
- a cooler for cooling the molten slag supplied to the slag pot
- wherein the slag pot includes a waste heat discharge pipe formed at an upper portion thereof so as to discharge hot steam and hot air generated upon cooling the molten slag, and
- wherein the waste heat discharge pipe is connected to a heat exchanger to produce hot water by using heat recovered from the hot steam and the hot air.
