Use high-pressure pumps and high-pressure micro nozzles to generate mist particles that are suitable for the on-site environment to adsorb dust and reduce dust. This method utilizes precision manufacturing technology to produce nozzles that comply with fluid mechanics principles. At the same time, high-pressure water is generated by a high-pressure pump and pressurized to 7MPa, which is then transported to the nozzles through a high-pressure pipeline system to spray fine water mist. The manufacturing of nozzles requires advanced technology. The ultra-high pressure spray dust suppression equipment enables the droplets to reach 5-100 microns, which is suitable for different dust environments. At the same time, it greatly improves the evaporation efficiency, absorbs heat in the process of water vaporization, reduces the temperature, and increases the relative humidity of the air. Due to the increase in air humidity, harmful dust in the air will be greatly reduced, achieving the effect of purifying the air. There is no water droplet phenomenon, fine atomization, and large surface area during use.
