An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

In an example, an electrostatic spray module includes a base unit formed of a sturdy, rigid, liquid impermeable, electrically insulative material and a cover formed of a sturdy, rigid, liquid impermeable, electrically insulative material and sized for covering the base unit. The base unit and the cover configured for mating engagement together so as to form a liquid impermeable, electrically insulative, protective enclosure when the module is in a closed state to keep the internal components clean and dry and prevents system form high voltage shorting and prevents leakage of current by inhibiting a high voltage from establishing a return path to ground. The spray module includes a quick access latch and gasket systemwith no tools required to open for maintenance. The module includes integral place holders for components including air supply manifold and variable voltage supply to provide a selectable high voltage level to accommodate various spraying application.

A spray-gun apparatus, comprising a spray-gun handle, a spray-gun tube-body, and a connection adapter; wherein the connection adapter is connected between the spray-gun handle and the spray-gun tube-body; wherein the first conduction tube is connected with the spray-gun handle and the spray-gun tube-body to use as a gas output path, and the second conduction tube is connected with a second cover-body to use as a gas suction path. Thereby, the gas sent from the spray-gun handle is blown out through the first conduction tube of the connection adapter and the spray-gun tube-body, and the water-sucking tube set inside the spray-gun tube-body will be made to spray liquid; and the second conduction tube of the connection adapter is used to connect a gas suction apparatus, so that the gas around the second conduction tube can be sucked into through the second conduction tube of the connection adapter.

A system and a method for generating a respirable dry powder aerosol (15) from a liquid solution or liquid suspension at a respirable dry powder aerosol volume flow (91). A liquid aerosol generating nozzle (3) generates from the liquid solution or liquid suspension a liquid aerosol (13) that is diluted by dilution gas (4) and dried in a cylindrical evaporation chamber (6) to generate a dry powder aerosol (14) that is subsequently concentrated by a cylindrical single linear slit aerosol concentrator (9). The system and method may include heliox as a gas, specifically dilution gas (4), for enhancing both the drying process in the cylindrical evaporation chamber (6) and for enhancing the concentration efficiency, but also as a nozzle gas (2) for enhancing generating the liquid aerosol (13) from the liquid solution or liquid suspension.

An apparatus and a method for mixing and atomizing a hydrocarbon stream is disclosed. The apparatus comprises of an inner conduit having a first inlet for receiving the hydrocarbon stream, and a second inlet for receiving a primary dispersion stream. The inner conduit produces a primary mixture comprising the hydrocarbon stream and the primary dispersion stream. The apparatus further includes an outer conduit having a third inlet for receiving a secondary dispersion stream. Further, said inner and outer conduits together define an annular passage. The distal end of the annular passage defines a second set of orifices for allowing the secondary dispersion stream flowing there-through to come in contact with the primary mixture and thereby dispensing the secondary mixture so obtained through an outlet.

An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.
