Abstract
An aerosol delivery apparatus is used to deliver an aerosol into a reaction chamber for chemical reaction to produce reaction products such as nanoparticles. A variety of improved aerosol delivery approaches provide for the production of more uniform reaction products. In preferred embodiments, a reaction chamber is used that has a cross section perpendicular to the flow of reactant having a dimension along a major axis greater than a dimension along a minor axis. The aerosol preferably is elongated along the major axis of the reaction chamber.
Claims28
A reaction system comprising:
- an elongated reaction chamber having an outlet along a reactant path, the reaction chamber with a cross section perpendicular to the reactant path, the cross section having a dimension along a major axis greater than a dimension along a minor axis;
- and
- an aerosol delivery apparatus comprising an aerosol generator, the aerosol delivery apparatus being connected to the reaction chamber to deliver a flow of an aerosol along the reactant path, the aerosol being elongated perpendicular to the flow of the aerosol along the major axis of the reaction chamber relative to the extension of the aerosol along the minor axis of the reaction chamber.
A reaction system comprising:
- a reaction chamber having an outlet along a reactant path;
- and
- an aerosol delivery apparatus connected to the reaction chamber to deliver an aerosol along the reaction path, the aerosol delivery apparatus comprising an ultrasonic aerosol generator having a solid atomization surface operably connected to an ultrasonic transducer, the atomization surface having a opening connected to a liquid flow conduit such that flow from the conduit flows along the atomization surface.
A reaction system comprising:
- a reaction chamber having an outlet along a reactant path, wherein the reaction chamber is configured to have a beam of radiation projected along a radiation path intersecting the reactant path;
- and
- an aerosol delivery apparatus comprising:
- a delivery tube connected to the reaction chamber to deliver an aerosol along the reactant path;
- a gas supply tube flowing into the delivery tube;
- and
- an aerosol generator comprising a sealed liquid conduit terminating at a solid atomizer surface wherein liquid from the conduit flows directly over the atomizer surface, the aerosol generator being oriented to produce an aerosol along a path within the delivery tube leading into the flow from the gas supply tube.
A reaction system comprising:
- a reaction chamber having an outlet along a reactant path;
- and
- an aerosol delivery apparatus comprising:
- a delivery tube connected to the reaction chamber to deliver an aerosol along the reactant path;
- an aerosol chamber in fluid communication with the delivery tube, the aerosol chamber holding a supply of liquid;
- a gas supply tube flowing into the aerosol chamber;
- and
- an aerosol generator oriented to produce an aerosol within the aerosol chamber above the supply of liquid without flow into the delivery tube, the aerosol generator being connected to a liquid supply tube, wherein aerosol is directed to the delivery tube only through flow of gas.
