A spray drying system for drying liquid into powder including a plurality of processing towers each including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. The powder collection chamber of each processing tower being configured to discharge power to a common conveyor system.

In a mist nozzle, a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to the mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow introduces into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side. Therefore, it is possible to promote atomization of the liquid in the gas-liquid mixing section and spray a liquid having a smaller particle diameter.

An electrostatic spray system includes an electrostatic tool, a spray tip assembly configured to receive a coating material, and an airflow to atomize and charge the coating material, and spray the coating material in an airflow direction. The spray tip assembly includes a first air cap horn having a recess in a first distal surface, a first charging pin disposed within the recess, and a grounded pin coupled to the spray tip assembly. The first charging pin and the grounded pin are configured to produce an electric field that charges the coating material.

A method to quickly change a nozzle assembly suitable for use in a liquid metal atomizing process in which a liquid metal held in a liquid metal reservoir and exiting said metal reservoir through a reservoir opening is atomized by an atomizing fluid to form a metallic spray in an atomizing tower. A sliding nozzle assembly system in which replacement nozzles can be changed on the fly during production.

The invention provides an analytic nebuliser device for delivering a sample in aerosolised form, the device comprising a nebuliser nozzle configured to receive a flow of said sample and generate a plume of aerosolised sample spray and a chamber configured to receive a flow of make-up gas and connecting with a plurality of microchannels having outlets arranged around and adjacent to said nebuliser nozzle wherein the microchannels are configured to produce a make-up gas stream with high linear velocity around said aerosolised sample spray to shape and direct said plume. The invention extends to a mass spectrometry or spectroscopy system including the above analytic nebuliser device, to provide in operation the aerosolised sample spray to an ionisation device of the system.

An apparatus is provided. The apparatus can include a housing having a first end and a second end. The first end can include a sample inlet and a gas inlet. The second end can include a sample outlet and a gas outlet. The apparatus can also include a sample delivery passage extending within the housing and fluidically coupling the sample inlet to the sample outlet. The apparatus can also include a gas delivery passage extending within the housing and fluidically coupling the gas inlet to the gas outlet. Systems and methods including the apparatus are also provided herein.

Provided is an atomization nozzle including: a nozzle body member having a gas ejection path and a gas ejection port; a liquid nozzle member having a liquid ejection path and a liquid ejection port, a tip portion of the liquid nozzle member being inserted through the gas ejection path; a pattern adjustment groove that produces a swirling flow in the gas ejection path; and a spraying pattern adjustment member having a communication flow path and a blocking portion, where a spraying pattern can be changed by switching between a first position in which the pattern adjustment groove and a gas supply flow path are in communication via the communication flow path and a second position in which the pattern adjustment groove is covered by the blocking portion. Also provided are an atomization device, a spraying device, and a spraying method.

Provided are nozzle assemblies for a spraying apparatus having an outer wall (146) having opposed inner and outer surfaces, a central aperture (136) extending through the outer wall, and a pair of auxiliary apertures (158) disposed on the outer wall (146). Each auxiliary aperture is aligned along a respective auxiliary axis (162) and areas of the inner surface (164) of the outer wall (146) adjacent to the auxiliary apertures (158) are countersunk to define ledges (166) that are axially symmetric about the auxiliary axes (162). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.

Hydrodynamic focusing of two fluid steams provides a novel micro printing technology for printed electronics and other high performance applications.
