The atomization form of tungsten carbide atomization nozzle can be divided into pressure atomization, rotary atomization, electrostatic atomization, ultrasonic atomization and bubble atomization. Because of its good atomization effect and the advantages of wide coverage, it is widely used in spraying, dust removal and humidification in agricultural production and industrial manufacturing. The tungsten carbide pressure atomization nozzle means that under the action of the high pressure of the liquid, the jet is sprayed from the nozzle at a high speed and suspended in a static or low-speed airflow to form an atomization. According to the different internal structure of the nozzle, it can also be subdivided into direct spray nozzle atomization and centrifugal nozzle atomization.
The principle of the rotary atomization nozzle is to supply liquid to the high-speed rotation center, so that the liquid is thrown out by centrifugal force and aerodynamic force to form an atomization effect. When the liquid flow rate is small, the centrifugal force is greater than the surface tension of the liquid, and a few large droplets are thrown out on the edge of the turntable and split directly. When the flow rate and speed increase, the liquid is drawn into many filamentous jets and becomes extremely unstable. After a certain distance from the disk edge, the liquid separates into small droplets due to friction with the surrounding air. As the flow rate and speed increase to a certain extent, the formed liquid film expands outward and becomes thinner, and at the same time it rubs with the surrounding air to separate and atomize. The electrostatic atomization, bubble atomization and ultrasonic atomization are all medium-type atomization nozzles. This type of nozzle enhances the fluidity of the surrounding airflow. It is formed by high-speed or even supersonic contact with low-speed liquid or liquid film to generate friction and vibration. Small droplets. Compared with other types of nozzles, tungsten carbide nozzles can achieve spray effects without an air compressor, and their atomized shape is generally circular or fan-shaped. In addition, fog nozzles also play a very important role in air conditioning. It is configured with the air-conditioning exhaust pipes, and the atomized water mist can effectively reduce the heat generated during the working process of the air conditioner.
