Publication number: 20230058407Abstract: A nanobubble nozzle includes a body; an inlet for receiving a liquid; an outlet for discharging the liquid with nanobubbles; a forward channel extending through the body from the inlet to the outlet for transmitting the liquid, the forward channel having a venturi throat; a return channel extending from the outlet to recirculate a portion of the liquid and mix it with a gas to form a two-phase mixture; and an inlet port connecting the return channel to the venturi throat. The liquid flow through the throat creates a suction drawing the two-phase mixture into the throat. A cross-sectional area of the forward channel decreases from the inlet to the throat and increases from the throat to the outlet so that an internal pressure lower than an external pressure outside the body and lower than a vapor pressure of the liquid flowing through the throat is provided at the throat.Type: ApplicationFiled: August 18, 2022Publication date: February 23, 2023Inventors: Kimbal A. Hall, Sophie A. Waterhouse

Publication number: 20220126148Abstract: A nozzle for dispensing a fluid having a barrel having a proximal end and a distal end, the barrel having a passage defined by a first internal surface extending between the distal end and the proximal end, and an orifice defined by a second internal surface at the distal end of the barrel, a stem located at least partially in the barrel, the barrel is movable in relation to the stem to switch between a low pressure mode and a high pressure mode, a shaper located around an outer surface of the distal end of the barrel, the shaper being movable in relation to the barrel to switch between a low pressure fog mode and a low pressure stream mode. The nozzle is configured to dispense the fluid in a straight stream or fog in both the low pressure mode and the ultra-high pressure mode. The orifice is also configured to provide flushing capability for the ultra-high pressure mode while operating in the low pressure mode.Type: ApplicationFiled: October 26, 2020Publication date: April 28, 2022Inventors: James B. Hansson, Kimbal A. Hall, Daniel Bateman, David C. White

Patent number: 11097232Abstract: A static mixer includes a tubular body having a sidewall with an upstream end, a downstream end opposite the upstream end, and an inner surface. The upstream end has a surface defining an upstream opening into the body. The downstream end has a surface defining a downstream opening exiting the body. The upstream opening, the downstream opening, and inner surface define a passageway through the body for transport of a first fluid therethrough. A primary fin may depend from the inner surface of the body and into the passageway. The primary fin may have a curved fin with a flow surface. A secondary fin may extend into the passageway adjacent to the primary fin, the secondary fin may have a curved flow surface that curves opposite to the flow surface of the primary fin. The secondary fin may be offset upstream or downstream from the primary fin.Type: GrantFiled: August 11, 2020Date of Patent: August 24, 2021Assignee: Westfall Manufacturing CompanyInventors: Robert W. Glanville, James M. Daniel, Kimbal Hall, Scott A. Olson

Publication number: 20150093295Abstract: A distributor for a circulating dry scrubber reactor includes a venturi section with a venturi section wall extending from a venturi section inlet to a venturi section outlet along a longitudinal axis, with the venturi section inlet connected to an inlet plenum and the venturi section outlet connected to a circulating dry scrubber reactor. A hub is mounted within the venturi section wall with an annular converging-diverging flow path defined between the venturi section wall and the hub for distribution of gas flow from the venturi section outlet into a circulating dry scrubber reactor space and for maintaining stable bed fluidization in a CDS system at a comparatively low system pressure loss.Type: ApplicationFiled: October 9, 2014Publication date: April 2, 2015Inventors: Matthew Quitadamo, Kimbal Hall, Martin J. Kozlak, Angelos Kokkinos
