Two Types Of Atomization Of Atomized Nozzles
May 06, 2018

Atomizing nozzles have a good reputation in the spray field for their spray effect. But few people know that the atomizer nozzles actually have two common sprays, that is, media atomization and mechanical atomization.

I. medium atomization.

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

Air bubble atomization

The advantages of aerosol atomization are that the gas consumption is low, the atomization quality is high and the atomization effect is not affected by the diameter of the outlet. Therefore, air bubble atomization is suitable for high viscosity liquid fuels such as atomized heavy and residuum. Bubble atomizing principle is the compressed air is injected into the liquid, and made them both in atomization nozzle mix indoor form stable bubble two-phase flow, leave the spray nozzle export dramatic changes in a very short distance, its ballooning until burst, further will be wrapped in the surrounding liquid membrane made of broken more subtle liquid fog particles.

Pneumatic atomization

Pneumatic spray can be in the lower oil supply pressure to obtain the good atomization effect, you are using fuel with the high viscosity also can obtain higher atomization quality, and can be adjusted for a wide range of, the use of flexible. The principle of pneumatic atomization is to form a high velocity air flow by a certain pressure gas, which causes a high relative speed between the gas and fuel to achieve the purpose of atomization.

2. Mechanical atomization.

Mechanical atomizing is mainly rely on the high-speed jet fuel under the action of pressure difference for fuel atomization, and can be subdivided into direct type, centrifugal and rotary atomization three, atomizing nozzle atomization can make liquid fuels into very small particles, uniform size liquid fog in order to increase the contact area between the liquid fuel and combustion air, can effectively promote the evaporation, which makes the fuel combustion efficiently, and the more fine atomized particles burning more fully. Therefore, choosing a good atomizing nozzle is an important way to improve production efficiency and save energy.
