Fluid recirculation system for use in vapor phase particle production system
A method of and system for recirculating a fluid in a particle production system. A reactor produces a reactive particle-gas mixture. A quench chamber mixes a conditioning fluid with the reactive particle-gas mixture, producing a cooled particle-gas mixture that comprises a plurality of precursor material particles and an output fluid. A filter element filters the output fluid, producing a filtered output. A temperature control module controls the temperature of the filtered output, producing a temperature-controlled, filtered output. A content ratio control module modulates the content of the temperature-controlled, filtered output, thereby producing a content-controlled, temperature-controlled, filtered output. A channeling element supplies the content-controlled, temperature-controlled, filtered output to the quench chamber, wherein the content-controlled, filtered output is provided to the quench chamber as the conditioning fluid to be used in cooling the reactive particle-gas mixture.
1. A method comprising:
plasma vaporizing a precursor material using a first gas, thereby producing a vaporized particle-gas mixture;
quenching the vaporized particle-gas mixture using a conditioning fluid comprising a second gas, thereby producing a cooled particle-gas mixture comprising a plurality of particles comprising the precursor material;
removing the plurality of particles from the cooled particle-gas mixture, thereby producing a filtered output comprising the first gas and the second gas;
adjusting an amount of the filtered output, thereby producing a content-controlled, filtered output;
supplying the content-controlled, filtered output as the conditioning fluid for quenching the vaporized particle-gas mixture.
2. The method of claim 1 , further comprising reducing pressure of the filtered output by venting a portion of the filtered output if the pressure exceeds a predetermined threshold.
3. The method of claim 1 , wherein adjusting the amount of the filtered output comprises venting a portion of the filtered output.
4. The method of claim 1 , wherein the filtered output has a temperature, and the method further comprises controlling the temperature of the filtered output.
5. The method of claim 1 , wherein adjusting the amount of the filtered output comprises adjusting an amount of the second gas in the filtered output.
6. The method of claim 5 , wherein adjusting the amount of the second gas in the filtered output comprises adding additional second gas to the filtered output.
7. The method of claim 1 , wherein adjusting the amount of the filtered output comprises adjusting an amount of the first gas in the filtered output.
8. The method of claim 7 , wherein adjusting the amount of first gas in the filtered output comprises adding additional first gas to the filtered output.
9. The method of claim 1 , further comprising temporarily storing the filtered output before adjusting the amount of the filtered output.
