Abstract
Excessive wear is eliminated in a distributor utilized in a bottom-blown oxygen steelmaking converter for distributing oxygen and entrained lime to the converter tuyeres by the provision of a spiral ramp that extends between the inlet and outlet regions of the affected portion of the distributor. The ramp is arranged to mechanically separate the entering oxygen-lime mixture from that flowing through the affected region thereby preventing the interference between the two flows and the wear-producing flow acceleration attendant therewith.
Claims13
A distributor manifold comprising
- a. a hollow cylindrical body;
- b. means dividing the interior of said body into axially spaced portions;
- c. means connecting said portions into mutual fluid communication;
- d. inlet means for introducing supply fluid to one of said portions and for imparting a spinning motion therein whereby said fluid is induced by cyclonic action to traverse a path from said one portion through said connecting means to the other of said portions;
- e. means for discharging supply fluid from the other of said portions;
- and
- f. baffle means diverting the path of fluid flow away from registry with supply fluid introduced through said inlet means.
In a steel refining vessel having a plurality of tuyeres penetrating the bottom thereof for blowing a mixture of gas and solid particles upwardly into a molten charge within said vessel and feeder lines connecting with each of said tuyeres the improvement comprising a distributor manifold for supply of mixture to said feeder lines including:
- a. a hollow, generally cylindrical body having closed ends attached to the bottom of said vessel;
- b. plate means intermediate the ends of said body dividing the interior thereof into vertically spaced chambers;
- c. a connecting tube open to both chambers connecting the same in mutual fluid communication;
- d. inlet means for introducing said mixture to one of said chambers and for inducing a spinning motion therein whereby said mixture is induced by cyclonic action to flow from said one chamber through said connecting tube to the other of said chambers;
- e. means connecting said feeder lines to said other chamber;
- and
- f. baffle means diverting the flow path of said mixture away from registry with the mixture passed through said inlet means.
