Claims
- 1. An apparatus for producing carbon black including a reactor defining a precombustion chamber, reaction chamber and a quench chamber with said precombustion chamber being upstream of the reaction chamber and said reaction chamber being upstream of the quench chamber, said reactor having an outlet downstream of the quench chamber; said reactor having means defining a first inlet opening into at least one of said precombustion chamber and said reaction chamber and operable for introducing a make hydrocarbon into at least one of said precombustion and reaction chambers; wherein the improvement includes:
- said reactor having means defining a second inlet opening generally tangentially, relative to the recombustion chamber, into the precombustion chamber and operable for introducing combustion gases into the precombustion chamber in one of a counterclockwise direction and a clockwise direction for vortex flow along the reaction chamber, said combustion gases when hot contact the make hydrocarbon to produce a smoke containing carbon black, said smoke also flowing in vortex flow along the reaction chamber;
- said reactor having means defining at least one third inlet opening generally tangentially, relative to the quench chamber, into said quench chamber and operable for introducing quench fluid into the quench chamber in the other one of the counterclockwise direction and the clockwise direction for flow counterrotational to the vortex flow of smoke; and
- a source of quench fluid connected to said third inlet.
- 2. An apparatus as set forth in claim 1 including:
- a venturi in said reaction chamber.
- 3. An appartus as set forth in claim 1 wherein:
- there is a plurality of said third inlets.
- 4. An apparatus as set forth in claim 1 including:
- a heat exchange means in flow communication with said reactor outlet and operable for cooling said smoke, said heat exchange means having an outlet; and
- first conduit means communicating between said third inlet and said heat exchange means outlet forming a flow path to the third inlet for cooled smoke from the heat exchange means wherein said cooled smoke is used as quench fluid.
- 5. An apparatus as set forth in claim 4 including:
- a venturi in said reaction chamber.
- 6. An apparatus as set forth in claim 5 wherein:
- there is a plurality of said third inlets.
- 7. An apparatus as set forth in claim 4 including:
- second conduit means connected to said heat exchange means outlet for flow of smoke therethrough; and
- filter means connected to said second conduit means operable for receiving a portion of the smoke from the heat exchange means and operable to separate said portion of smoke into a gas phase and a carbon black phase.
- 8. An apparatus as set forth in claim 7 including:
- a fourth inlet means opening into said second conduit means and operable for introducing a quench fluid into said second conduit means.
