Mist sprayer e.g. for cooling or disinfecting air in enclosed building has centrifugal fan to generate gas flow carrying liquid droplets

摘要

The mist sprayer (1) consists of a centrifugal fan (2) with an axial intake (3) and radial outlet (6), generating a gas flow to transport liquid droplets produced by diffusion nozzles (10) located in or above the radial gas outlet flow. The fan can be mounted on a support that also acts as a supply pipe. The sprayer can also have a series of deflector shutters pivoted parallel to the fan's axis of rotation to control the direction of the flow, with the fan, nozzles and shutters being enclosed in a housing (4) with a polygonal outer edge.
