Problems solved by technology

The conventional rotary mechanical atomizing nozzle has a disadvantage: the distribution shape of the droplets in the space is a hollow cone, and there is no droplet in the middle of the cone.
The disadvantage of the conventional rotary mechanical atomizing nozzle is that the droplets are not uniformly distributed in space, which weakens the heat and mass transfer effect.

Embodiment Construction

[0013] The central spray multi-layer rotary liquid atomizing nozzle of the present invention relies on pressure to accelerate the liquid to form a rotating liquid film or liquid column, and the liquid film or liquid column ruptures to form liquid droplets, thereby realizing the purpose of liquid atomization.

[0014] The central spray multi-layer rotary liquid atomizing nozzle of the present invention can accelerate the liquid into a rotating liquid film or liquid column in three ways: circle, cone and helix.

[0015] The structure of the central spray multilayer rotary liquid atomizing nozzle of the present invention is as follows: figure 1 As shown, it includes a shell 1, the shape of the inner cavity of the shell 1 is hollow, and the two ends of the shell 1 respectively form the liquid inlet and the liquid outlet. At the axial position of the inner cavity of the shell 1, there are conical rotators connected to each other 3 and a circular rotator 2, an axial end of the circu...

Abstract

The present invention is one multilayer rotary liquid atomizing nozzle with pressurizing atomization and central spraying. The multilayer rotary liquid atomizing nozzle consists of peripheral rotator, conic rotator, spiral spacing shells and outer casing. Each of the conic rotator and the spiral spacing shells has spiral liquid groove. The peripheral rotator and the conic rotator spray liquid in the center, and the spiral liquid grooves spray multilayer liquid drops for filling the atomizing space. The flow rate may be altered through changing the number of the number of the spiral spacing shells. The present invention is suitable for direction contact heat exchange between gas and liquid, adsorption of dust with liquid and other fields.

Description

technical field [0001] The invention belongs to the technical field of fluid mechanics, and relates to a liquid atomization device, in particular to a central spray multi-layer rotary liquid atomization nozzle. Background technique [0002] When the gas-liquid is in direct contact with heat exchange, atomizing the liquid can greatly increase the surface area of ​​the liquid and enhance the heat and mass transfer effect. Therefore, the liquid atomization device is widely used in thermal power, chemical industry, metallurgy and other industries. The rotary mechanical atomizing nozzle relies on the pressure to accelerate the liquid to form a rotating liquid film or liquid column, and the liquid film or liquid column breaks to form droplets, so as to achieve the purpose of liquid atomization. Conventional rotary mechanical atomizing nozzles have a disadvantage: the distribution shape of the droplets in space is a hollow cone, and there is no droplet in the middle of the cone. T...
