Air atomizing nozzle is the use of compressed air and liquid impact friction, liquid produce very uniform and small atomizing effect, the average diameter of atomizing particles reaches 50 microns and below. The structure of air atomizing nozzle is divided into pressure atomization and siphon atomization. The spray device has two ways: mixing inside and mixing outside. The atomization principle is air break and impact. The atomization effect is ideal. It is not suitable for the liquid with viscosity. After the external mixing atomizing gas liquid is sprayed out of the nozzle hole, the liquid is atomized by friction with high-speed air flow. The atomization principle is tangential stress generated by friction, and the atomization effect is general. Suitable for comparison of liquids with viscosity. The advantage of air atomizing nozzle is that the atomizing droplets are very fine, and the liquid with high viscosity can be atomized. The disadvantage is the need toconsume compressed air.

General application of air atomizing nozzle

The application field of atomizing nozzle is very wide, there are different applications in different industries. Can spray irrigation in agriculture, in industrial application can be used to spray humidification, lubrication, disinfection, such as environment can sulfur removal in the desulfurization tower, in power plants, chemical plants can be used to dry fog dust suppression, at the same time can also be used in extinguishing fire industry, in real life, can be used in the humidifying, disinfection, flavoring, etc.

7) The spray device has internal mixing and external mixing
 

Atomizing effect of air atomizing nozzle

The most important role of air atomizing nozzle is its atomization effect. The atomization effect should be: the spray is symmetrical, the atomization is uniform, the edge is clear, and only a few paint particles can exist outside the spray edge.
Under the same conditions, the atomization fineness of air atomizing nozzle decreases with the increase of air hole diameter. When the gas-liquid ratio is 0.4 and the air pressure is 5bar, the atomization fineness is below 10um.
When the air pressure increases from 2bar to 5bar, the atomization particle size decreases from 25um to about 7um. When the air pressure continues to increase and exceeds 5bar, the curve flattens out. At this time, increasing air pressure will not lead to further thinning of atomization.
The atomization fineness of the nozzle decreases with the increase of the number of pores. When the number of pores is more than 6, the decreasing trend of atomization fineness becomes slow. When the number is between 4 and 6, the average particle size is below 10um  

Air atomizing nozzle and other common nozzle difference

1) The atomizing nozzle is a fog, and it is a very small fog, but the ordinary nozzle is not as small as the air atomizing nozzle spray effect.
2) The work of the air atomizing nozzle is to have the effect of air compressor to spray the fog. Generally, the ordinary nozzle does not need any compressor and is directly connected to the water pipe. As long as the water has a certain pressure, the spray effect can be sprayed.
3) Air atomizing nozzles generally have only fan-shaped and circular spray shapes. The shapes of ordinary nozzles are fan-shaped, solid cone, hollow cone, circular and other bell spray effects.
 
 
Air atomizing nozzle refers to double fluid atomization, under the condition of liquid pressure is not too high, through the external gas atomization, atomization effect is good, small particle size can reach dozens of μ, this kind of nozzle and particularly mixed and mixed, mainly nozzle structure, mixing outside can spray some viscous liquid.
Atomizing nozzle is a general name, the liquid can spray into mist are called atomizing nozzle.
