2 common atomization methods for atomizing nozzles

Atomization nozzle, in the spray field with its good spray effect and enjoy a good word of mouth. But few people know that atomizing nozzles have 2 common types of spray, that is, medium atomization and mechanical atomization.

One, medium atomization

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

Air bubble atomization

The advantages of bubble atomization are low gas consumption, high atomization quality, and the atomization effect is basically not affected by the diameter of the outlet. Therefore, the bubble atomization is more suitable for the high viscosity liquid fuel such as the atomization weight, the residual oil and so on. The principle of the compressed air bubble atomization is injected into the liquid, and the two formed in the mixing chamber nozzle stable bubbly two-phase flow in nozzle outlet, leaving a very short distance change, promote its rapid expansion until rupture, further broken around the film to become more liquid mist particles fine

Pneumatic atomization

Pneumatic atomization is able to achieve good atomization effect under low oil pressure. It can also achieve high atomization quality when using high viscosity fuel oil, and it can be adjusted in a wide range and flexible. The principle of pneumatic atomization is to form high speed airflow by means of a certain pressure gas, so as to form a high relative velocity between gas and fuel to achieve the purpose of atomization.

Two. Mechanical atomization

Mechanical atomization mainly depends on the high speed jet produced by the fuel pressure under the pressure difference, so that fuel can be atomized, and it can be subdivided into three types: direct, centrifugal and rotary atomization.

Spray atomizing nozzle can increase the contact area between the liquid fuel and combustion air to spray the liquid fuel into very small particles, uniform size, can effectively promote the evaporation, so that the fuel can be fully efficient combustion and atomization of the finer particles combustion more fully. Therefore, the choice of good atomizing nozzle is an important way to improve the efficiency of production and save energy.
