Description

Technical Field

[0001] This utility model relates to the technical field of atomizing nozzles for de-cooling steam systems, specifically a multi-planetary spray hole atomizing nozzle. Background Technology

[0002] With technological advancements, atomizing devices are widely used in agriculture, industry, environmental control, and daily life. In agriculture, they are used for pesticide spraying and greenhouse humidification; in industry, they are used for cooling and dust removal; and in environmental control, they are used for dust suppression spraying and landscape fogging. The atomizing nozzle is the core component of the atomizing device, and its performance directly determines the diameter of the atomized droplets, thus determining the atomization effect. Most existing atomizing nozzles operate on the principle of being driven by an electric fan, utilizing the Venturi principle to draw in air at high speed. Sufficient kinetic energy is provided to the air within the nozzle, causing the gas to collide with the droplets at high speed, producing dry mist particles, which then overflow as dry mist particles.

[0003] Chinese invention patent application No. 201810533700.5 proposes a novel atomizing nozzle structure. The outer surface of the bottom wall of the atomizing chamber facing the air outlet of the fan is a conical surface. Several through holes are evenly arranged circumferentially on the outer surface of the conical surface. The through holes are set at a certain angle relative to the radial direction. The inner end of the through holes is connected to the atomizing chamber and the outer end is connected to the air outlet of the fan. The bottom wall is provided with a liquid outlet hole in the middle, which is connected to the liquid outlet pipe.

[0004] The above-mentioned atomizing nozzle operates on the principle of pneumatic atomization, which uses compressed air to generate a high-speed airflow to disperse the liquid into small particles. It is suitable for occasions that require rapid evaporation and mixing. However, this type of atomizing equipment requires an electric fan connected to it. The electric fan is installed inside the housing, which increases the cost and makes the structure more complex.

[0005] Therefore, this project aims to design a simple, easy-to-manufacture, energy-saving and environmentally friendly atomizing nozzle that allows liquid to pass through a specially designed nozzle orifice under high pressure or high-speed airflow. Summary of the Invention
