Abstract:
A steam atomizing liquid spraying system which in the preferred embodiment includes a spray nozzle assembly having a central liquid passageway for coupling to a liquid supply and a plurality of spray nozzles each removably mounted in the nozzle body and having a respective central steam passage communicating with a steam supply. The spray nozzles each further have a plurality of circumferentially spaced liquid accelerating passages that communicate with a respective angled passage of the nozzle body which in turn communicates with the central liquid supply passageway for directing liquid into the central steam passage of the spray nozzle for interaction with steam directed through the central steam passage and atomization of liquid discharging from the spray nozzle. In an alternative embodiment, a single spray nozzle insert is utilized.
Abstract:
A fluid flow nozzle is provided that comprises an elongated body having an inlet end and an outlet end, and defining a channel extending therethrough in which the channel includes an inlet channel and an outlet channel having an outlet diameter that is less than the inlet diameter. The channel further defining a tapered channel extending from the inlet channel to the outlet channel with a plurality of vanes or grooves circumferentially spaced around the tapered channel to increase flow velocity while reducing turbulence and divergence of the discharge stream.
Abstract:
The present invention is directed to simple and economical systems and methods for facilitating the control of dissolution of one or more gases into a liquid, such as water, while maintaining a constant flow of the liquid into and out of an enclosed vessel. Preferred gases for use with the disclosed systems and methods are oxygen, air, ozone, and carbon dioxide. Preferred applications include, for example, oxygenation and/or ozonation treatment of rivers, streams, lakes, ponds, and basins in natural, municipal, or industrial settings and wastewater treatment. More specifically, the present invention is directed to systems for delivering a fluid having a desired dissolved gas concentration that include, inter alia, a dissolution tank assembly that has a pressure vessel which defines an internal chamber for containing a fluid and provides a regulated, pressurized gas head space above the fluid; at least one liquid spray nozzle that permits passage of the fluid into the gas head space of the pressure vessel; and an outlet for discharging the fluid having a desired gas concentration from the pressure vessel. The systems further include a gas source in communication with the gas head space of the pressure vessel and a pumping mechanism for supplying the fluid to the spray nozzle of the dissolution tank, such that fluid droplets are formed and the gas contained within the pressurized head space is dissolved into the fluid. Also provided is a device for detecting the level of the fluid in the internal chamber of the pressure vessel and a mechanism for adjusting the level of fluid in the pressure vessel in order to achieve the desired dissolved gas concentration within the fluid. Preferred gases for use with method are oxygen, air, ozone, and carbon dioxide, and preferred applications include oxygenation and/or ozonation treatment of rivers, streams, lakes, ponds, wastewater and basins in natural, municipal, or industrial settings.
Abstract:
An ozone purification system for wastewater comprising an ozone diffusion reactor installable in or in fluid communication with wastewater collection tanks of septic or other wastewater systems. The reactor includes a pump that circulates wastewater through a gas-liquid mixing device, a contact volume, and a static mixer. The contact volume comprises an elongate length of contact piping and the static mixing chamber is configured to impart turbulence into the flow of the circulated wastewater and ozone gas.
Abstract:
Disclosed is a micro bubble generation device. The micro bubble generation device comprises: a rotating unit which receives a mixture of water and gas that flow thereinto, enables the water and the gas to be rotated by colliding with each other, and discharges the dissolved water; a dissolution tank which stores the dissolved water that is discharged from the rotating unit; and a nozzle unit which receives the dissolved water that flows thereinto, and generates micro bubbles in the water. Thus, micro bubbles having the dimension of 100nm or less can be generated in large quantities by using low power.
Abstract:
The present disclosure relates to apparatus designed to impregnate a sorbent. In some embodiments apparatus of the disclosure may comprise a mixing vessel having either a conical mixing chamber or an cylindrical mixing chamber designed to increase the contact surface area and/or contact/residence time of a sorbent and impregnant to produce compositions comprising an impregnated sorbent. Apparatus of the disclosure may also comprise one or more atomizers operable to produce atomized droplets of impregnant. The disclosure also provides methods for impregnation of a milled sorbent or an un-milled sorbent. Methods of the disclosure provide several technical advantages and may be cost effective. Impregnant sorbent compositions produced by methods and/or apparatus of the disclosure may have higher concentrations of an impregnant, a more uniform distribution of an impregnant and may have a greater sorbent efficiency.
Abstract:
Clarification system (1) of the flotation type for wastewater treatment comprising: at least one main tank (2) defining a vertical central axis X-X and having at least a bottom (3) and at least a lateral wall (4); at least one sludge collecting device (5) for sludge to be treated; at least one unit (20) for adding air bubbles to water and/or sludge to be treated; at least one water retaining tank (31); The unit (20) for adding air bubbles comprises: at least one duct (33) for a flow of water and/or sludge to be treated; at least one duct (34) for a flow of water added with air; and at least one mixing device (35) configured and dimensioned so that the flow of water added with air is positioned inside the flow of water and/or sludge to be treated and runs into the latter while expanding radially from the inside towards the outside or vice versa.
Abstract:
A mixing apparatus, puncturing mechanism, and cartridge are disclosed. The mixing apparatus has a housing and a drawer with a recess. Corresponding cartridges may be inserted into the drawer and slid into the housing to facilitate mixing a liquid with contents of the cartridge. The liquid may originate from a reservoir in the mixing apparatus or a direct line. Also inside the housing of the mixing apparatus is the puncturing mechanism. The puncturing mechanism has a nozzle configured to puncture a lid of a cartridge and inject liquid to mix with the contents of the cartridge. The puncturing mechanism is further configured to drive an internal puncturing unit inside of the cartridge through a lower portion of the cartridge to allow liquid from the nozzle and contents of the cartridge to be dispensed into a receptacle.
Abstract:
A chemical mixing apparatus has a mixing tank having an inlet and an outlet, means for introducing a liquid into the mixing tank, and a tubular conveyor assembly having a first end and a second end. The second end of the conveyor assembly is sealably connected to the inlet of the mixing tank. A portable hopper having a sealable inlet and a sealable discharge conduit is detachably and sealably connected to the first end of the conveyor assembly such that a solid chemical contained in the chemical storage chamber of the portable hopper may be transported within the portable hopper from a remote location and conveyed from the portable hopper to the mixing tank without exposing the area surrounding the mixing tank to the solid chemical.
