Abstract:
1. A quench chamber comprising: a frusto-conical body having a wide end, a narrow end, and a quench region formed between the wide end and the narrow end; a reactive mixture inlet configured to receive a reactive mixture comprising plasma energized precursor material from an output of a plasma reactor and to supply the reactive mixture into the quench region in the direction of the narrow end, wherein the quench region is configured to enable the reactive mixture to expand upon exiting the reactive mixture inlet; one or more conditioning fluid inlets separated from the reactive mixture inlet and configured to supply a conditioning fluid into the quench region along a plurality of momentum vectors of conditioning fluid that correspond to angles of a frusto-conical surface of the frusto-conical body in the direction of the narrow end via one or more openings different from the reactive mixture inlet, wherein a gap is formed between the reactive mixture inlet and the frusto-conical surface of the frusto-conical body, the gap acting as a channel for supplying conditioning fluid into the quench region, and the frusto-conical surface of the frusto-conical body is configured to produce a turbulent flow within the quench region, thereby promoting the quenching of the reactive mixture with the conditioning fluid to form a cooled gas-particle mixture; and a gas-particle mixture outlet disposed at the narrow end, the outlet configured to receive the cooled gas-particle mixture from the quench region.
