Abstract:
An emitter for atomizing and discharging a liquid entrained in a gas stream is disclosed. The emitter has a nozzle with an outlet facing a deflector surface having a closed end cavity. The nozzle discharges a gas jet against the deflector surface. The emitter has a duct with an exit orifice adjacent to the nozzle outlet. Liquid is discharged from the orifice and is entrained in the gas jet where it is atomized.
Abstract:
A fire suppression system is disclosed. The system includes a source of pressurized gas and a source of pressurized liquid. At least one emitter is in fluid communication with the liquid and gas sources. The emitter is used to establish a gas stream, atomize and entrain the liquid into the gas stream and discharge the resulting liquid-gas stream onto the fire. The emitter discharges the liquid-gas stream against a deflector surface having a closed end cavity therein.

Abstract:
In the method for interspersing a gas flow with liquid droplets, the liquid droplets are injected in a liquid injection plane into the gas flow, characterized in that an auxiliary gas is simultaneously injected with the liquid droplets into the gas flow. The injection speed of the auxiliary gas is larger than the injection speed of the liquid droplets so that the injected auxiliary gas stabilizes the injected liquid droplets with respect to trajectory and size, partly shields them from the gas flow and/or entrains them into the gas flow. By way of this one achieves an improved control of the spatial distribution of the liquid droplets and their size distribution. The liquid droplets penetrate the gas flow more efficiently than without an auxiliary gas. A preferred use is the online wet-cleaning of a gas turbine compressor.
Abstract:
A strand coating system and method including drawing (710) a strand having major and minor dimensions past an adhesive dispensing nozzle, orienting (720) at least a portion of the strand so that the major dimension of the strand is substantially parallel to a direction in which adhesive is dispensed from the adhesive dispensing nozzle as the portion of the strand is drawn past the adhesive dispensing nozzle, and applying (730) adhesive to the strand as the strand is drawn past the adhesive dispensing nozzle.
Abstract:
Fluid and air nozzle assemblies are capable of propelling streams of a cleaning fluid and air mixture onto a vehicle vision device, visible indicator, or sensor. These nozzle assemblies are mounted on a vehicle adjacent to the vehicle vision device, visible indicator, or sensor and positioned such that liquid and air jets from the nozzles intersect prior to impinging upon the vehicle vision device, visible indicator, or sensor to form a spray mixture that cleans the vehicle vision device, visible indicator, or sensor. These nozzle assemblies have an adjustment feature for the purpose of aiming the fluid-air spray toward the vehicle vision device, visible indicator, or sensor. The nozzle assemblies are associated with a control valve capable of connection in a pressurized air system on the vehicle and in the pressurized washer system for the windshield wipers and also capable of automatically directing liquid from the vehicle washer system and pressurized air on the vehicle to the liquid and air nozzles perform cleaning of a vehicle vision device, visible indicator, or sensor upon manual activation of the pressurized windshield washer system of the vehicle, upon activation of brakes, or upon timed intervals.
Abstract:
A combination spray apparatus which allows for the selection of several different flowable materials to be sprayed from a single unit and at the site of the unit itself. In the preferred manner, the spray apparatus includes a trigger nozzle as well as the selection of two different materials to be sprayed through a second barrel portion. An eductor it utilized to draw selected materials into a spray stream. The combination spray apparatus is operable with water pressures which are customary to most cities and industries.
Abstract:
A method serving the purpose of spraying a crop with a plant protective liquid. The liquid is sent out in the shape of a number of clouds (10) of atomized liquid in the direction of the crop (11) via a number of liquid nozzles (9) placed on a sprayer boom (8) which, at the same time, is driven across the crop (11). The nozzles (9) are adjusted to put each atomized liquid cloud (10) into whirling movement. The whirls (10) created thereby are stiff and stable against drifting. The liquid whirls (10) can be supported by a curtain of air whirls (14). By means of the method and the sprayer boom according to the invention, a crop can be sprayed efficiently with a minimum use of crop spray.
Abstract:
The present invention provides a nozzle, nozzle assembly, and method of use thereof for atomizing a liquid stream into a flat fan-shaped spray. The nozzle and nozzle assembly are particularly useful for atomizing a hydrocarbon feed into a catalytic cracking zone of a fluid catalytic cracking (FCC) process. The nozzle includes a nozzle tip that has at least three substantially vertical openings extending from the inner surface of the nozzle tip to the outer surface of the nozzle tip. The openings are angled from 0 degrees to about 75 degrees. The present invention also provides a nozzle assembly containing at least three nozzles of the present invention that are radially mounted around the perimeter of an area to be sprayed.
Abstract:
The invention relates to continuous gas fluidized bed polymerization of olefins, especially ethylene, propylene, or mixtures of these with other alpha olefins, wherein the monomer-containing recycle gas employed to fluidize the bed is cooled to condense out at least some liquid hydrocarbon. The condensed liquid, which can be a monomer or an inert liquid, is separated from the recycle gas and is fed directly to the bed to produce cooling by latent heat of evaporation. The liquid feeding to the bed can be through gas-induced atomizer nozzles (FIG. 2), or through liquid-only nozzles. The process provides substantially improved productivity of gas fluidized bed polymerization of olefins.
