Fluid injection assembly for nozzles
View Patent ↗A fluid mixing apparatus and method include a first fluid assembly having at least one fluid nozzle for providing a first fluid; a second fluid assembly having at least one fluid mixing nozzle sized and shaped to be received by the at least one fluid nozzle for providing a second fluid into the first fluid; a mixing region disposed where the at least one fluid nozzle and the at least one fluid mixing nozzle coact in spaced relationship for providing turbulence to the first and second fluids, thereby providing a fluid mixture thereof; and a passageway in communication with the mixing region for expanding the fluid mixture into a different phase.
1. A method of mixing fluids, comprising:
providing a first fluid in a first amount from a distribution manifold including a fluid nozzle having a receiving chamber, a passageway fluidly coupled to the receiving chamber, and a distribution chamber fluidly coupled to the passageway;
providing a second fluid in a second amount, from a fluid injection manifold having a fluid mixing nozzle extending through the distribution manifold into the fluid nozzle, to the first fluid at a ratio above a solubility limit for combining the first and second fluids, the fluid mixing nozzle having a tapered distal end disposed within the fluid nozzle receiving chamber proximate to the fluid nozzle passageway;
combining the first and second fluids in the ratio selected at a turbulent mixing region formed where the fluid nozzle and the fluid mixing nozzle coact in spaced relationship;
causing turbulence to the first and second fluids in the mixing region to mix the first and second fluids above their respective solubility limits into a uniform fluid mixture; and
expanding the uniform fluid mixture in a solid phase, or a solid and gaseous phase.
2. The method according to claim 1 , further comprising applying the phase mixture to an object to be treated with the phase mixture.
3. The method according to claim 1 , wherein the first fluid comprises CO 2 .
4. The method according to claim 3 , wherein the CO 2 is provided in a composition selected from a solid phase CO 2 , a gas phase CO 2 , a liquid phase CO 2 and combinations thereof.
5. The method according to claim 1 , wherein the second fluid comprises a fluid selected from nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, hydrogen, helium, ozone, water, ozonated water, halides, corrosives, acids, bases, oxidizers, peroxides and combinations thereof.
6. The method according to claim 1 , wherein at least one of the first fluid and the second fluid are provided above its solubility level with respect to the other.
7. The method according to claim 1 , wherein the first fluid is at a concentration of from 0.001 to 0.1 parts per unit volume of the second fluid.
