Device for introducing separated fluids through independent flow paths through bottom tuyeres in a rotating metallurgical converter

摘要

A mechanism and flow conduits for introducing and transporting a set of separated fluids and a stream of solid fines through passageway in a rotating metallurgical converter for introducing such fluids and solid fines into a liquid metal contained in the converter. Stationary conduits from flow sources connect to a non rotative sleeve which forms the external portion of a rotary joint able to introduce a set of separated fluids into the rotating converter passageways. Each separated stationary fluid conduit connects to port holes in the fixed sleeve to lead the flow to the interior of the sleeve, and connects a circumferential channel formed in rotating rings located between a rotating shaft affixed to the converter vessel trunnion pin and the static sleeve with a seal between each adjacent ring and corresponding channel. A port hole is located in each rotating channel ring for leading the fluid through internal flow paths inside and along the axis of the shaft body. The flows paths connect to a plurality of pipes contained inside the trunnion pin central bore, which, in turn, connect a set of port holes of a multi passageway elbow, which serves for leading the fluids and solid fines stream to the ring side end of the trunnion pin and changes the direction of the fluids and stream of solids by ninety degrees so as to direct such fluids to the botton pipe lines which finally end up in the converter bottom injection nozzles.
