What are the two types of atomization that are common to atomizing nozzles?

The atomizing nozzle enjoys a good reputation in the spray field for its good spray effect. However, few people know that atomizing nozzles actually have two common spray methods, namely, media atomization and mechanical atomization.

 

First, medium atomization

The atomization of the atomizing nozzle can be subdivided into bubble atomization and pneumatic atomization according to the different atomization medium.

 

1 bubble atomization

The atomization method of bubble atomization has the advantages of low gas consumption, high atomization quality, and atomization effect is basically not affected by the outlet diameter. Therefore, bubble atomization is more suitable for high viscosity liquid fuels such as atomized heavy and residual oil. The principle of bubble atomization is to inject compressed air into the liquid, and to form a stable bubble-like two-phase flow in the mixing chamber of the atomizing nozzle, which changes drastically at a very short distance from the exit of the atomizing nozzle, causing it to sharply Expand until it breaks, further shattering the liquid film wrapped around it into more fine liquid mist particles

The atomization nozzle atomization can make the liquid fuel into very fine particles and a uniform size liquid mist to increase the contact area between the liquid fuel and the combustion air, which can effectively promote evaporation, so that the fuel can be fully and effectively burned, and The finer the atomized particles, the more complete the combustion. Therefore, choosing a good atomizing nozzle is an important way to improve production efficiency and save energy.
