PNEUMATIC LIQUID SPRAYER WITH ACOUSTIC HEAD Russian patent published in 2018 - IPC A62C31/02 

FIELD: devices for liquid atomizing.

SUBSTANCE: invention relates to fluid spraying equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. This is achieved by the fact that in a liquid atomizer comprising a hollow cylindrical body connected to a nozzle where throttling openings are provided, the hollow body consists of a cylindrical part with an external thread for connection to the connection of a distributing pipeline for the supply of liquid, and two, hollow cylindrical belts connected in series and coaxial with it, and coaxially to the body, in its lower part, a nozzle made in the form of a glass is fixed, where in the bottom a vertical and inclined throttling holes are made at angle of 45° to the axis of the nozzle, and in the cylindrical body belt, at least one row of radial openings are formed, which axes lie in a surface perpendicular to the axis of the housing, the number of holes in each row being at least three, with the body and nozzle forming among themselves a number of coaxial inner chambers: cylindrical, and, between them a conical chamber is placed, one of the cylindrical chambers serves to supply the sprayed liquid, and the conical chamber and the cylindrical chamber are expansion chambers, and in the central part of the nozzle, a tube for supplying air (gas) is coaxially fixed, to one end of which, in its lower part, a hollow disk with a perforation facing the output cross-sections of the throttle openings of the nozzle. Diffuser is coaxially connected with a sprayer made in the form of a cylindrical shell, where a perforated disk is fixed on the cut, the perforation being in the form of a screw groove formed by the Archimedes spiral, in this case, the direction of the helix is performed in the opposite direction to the unwinding of the helix, that is made in the hollow disk of the acoustic head.

EFFECT: high efficiency of liquid atomizing.
