Abstract:
The invention concerns a spraying device for melt granulation in fluidised bed comprising a nozzle (2) with a feed channel for a liquid to be atomised, where the liquid is led through emulsifying means and into an internal mixing chamber for gas and liquid, before it is fed to the fluidised bed. The nozzle has a separate channel for the atomising gas fitted concentrically around the central liquid supply channel for the liquid to be atomised or nebulised. The mixing chamber surrounds the outlet zone of the liquid spray from the emulsifying means and the gas, allowing efficient mixing of high speed atomisation gas and liquid, and having an external gas cap (1) where fluidisation gas is channelled into a spout above the spraying device.
Abstract:
An internal cleaning apparatus includes a rotary shaft which, having a liquid flow passage, is provided so as to be axially rotatable, a revolving rotary shaft which, having a liquid flow passage connected to the liquid flow passage and being provided in a direction substantially perpendicular to the rotary shaft, is installed so as to be revolvable about the rotary shaft and axially rotatable, and a nozzle provided at a leading end of the revolving rotary shaft, wherein a gas flow passage is provided along the liquid flow passage of each of the rotary shaft and the revolving rotary shaft from a gas inflow opening provided in the rotary shaft, wherein a configuration is such as to eject a gas-liquid mixture flow having a gas supplied from outside the object to be cleaned mixed with the liquid ejected from the nozzle.
Abstract:
Provided is a heat treatment apparatus. The heat treatment apparatus includes a heating plate including a heater; a chamber case including a cooling chamber, and coupled to a lower portion of the heating plate; and at least one atomizing unit installed on the chamber case to generate liquid droplet aerosol by mixing a cooling liquid and a gas, and at the same time, to inject the liquid droplet aerosol into the cooling chamber.
Abstract:
A liquid spray device, comprising a container (1), a spray injection nozzle (2) for injecting oil spray into the container (1), a spray feeding path (5) for feeding oil spray in the container (1) to the outside of the container (1), oil (11) stored in the container (1), a gas exhaust port provided in the oil (11) by discharging gas into the oil (11), whereby the flow velocity of the oil spray in the spray feeding path can be increased and the amount of oil spray can be increased because an internal pressure of the container can be increased and an oil spray different from the oil spray from the spray injection nozzle can be produced.
Abstract:
A device for atomizing a liquid fuel comprising a central liquid fuel feed passage for feeding with liquid fuel an outer atomizing-gas feed passage for feeding with atomizing gas, these being coaxial overall, an atomizing head extending said passages, the head being equipped for each fluid with one or more ducts which converge into one or more nozzles made in the head and emerging in a combustion region in which the nozzles release a mixture of atomized liquid fuel and of atomizing gas, which head is held at the end of the coaxial passages by a nut screwed onto a wall of the outer passage, wherein the central liquid-fuel feed passage is surrounded by the atomizing-gas feed passage and the atomizing head includes a skirt surrounding inlets to the ducts for the liquid fuel, which skirt is received inside the central passage and the skirt and the said passage respectively have externally and internally complementing cross sections.
Abstract:
An assembly for dispensing a liquid composition in spray form including a wand section wherein fluid is transported through a capillary tube disposed within an outer tube, pressurized air being transported between the inside diameter of the outer tube and the outside diameter of the capillary tube. Both the outer tube and capillary tube connect with a common mixing chamber wherein the pressurized air and liquid is mixed, this mixture being expelled through a nozzle as an aerosol spray.
Abstract:
A fuel nozzle having two concentric flow paths, the interior flow path comprising a first swirl chamber having a first diameter, an exit chamber having a second diameter selected to be smaller than the first diameter, and a convergent section joining the first swirl chamber and the exit chamber. The exterior flow path comprises an annular second swirl chamber formed about the periphery of the exit chamber. The interior flow path has a fuel and air mixture flowing therethrough while the exterior flow path has air only flowing therethrough. Fuel in the interior flow path is caused to lie in a film and flow circumferentially about the internal wall of the first swirl chamber by air entering into the first swirl chamber through inlet holes which are configured to direct the air tangentially along the internal wall surface of the first swirl chamber. As the fuel film moves axially through the convergent section and into the exit chamber, the tangential velocity increases due to the smaller diameter of the exit chamber. Air in the annular second swirl chamber is directed into close association with the air and fuel leaving the exit chamber and the increased tangential velocity of the fuel film enhances the shearing effect of the air from the second swirl chamber on the fuel film to thereby break-up the fuel film into fine droplets at low fuel flow rates.
Abstract:
A spray head having a body provided with separate inlets for two fluids, the inlets having a common longitudinal axis and being in end abutting relation. One inlet leads to a chamber for receiving one of the fluids, the chamber being provided with means through which the fluid is discharged, and the other inlet leads to a post, manufactured simultaneously with the manufacture of the chamber and integral with the body. The post is located in the chamber and is hollow so that the other fluid is discharged therefrom by the aspirating action of the first, and the two fluids are commingled, the second fluid being atomized by the first. Various nozzle structures are disclosed from which the commingled discharges flow, the ultimate discharge being in the form of a cone, or a flat fan by the employment of opposed supplemental fluid jets, or non-circular in formation as shaped by appropriate terminus aperturing, or flattened and diverted by impact with an impingement surface in the path of the discharge.
