On-site demolition, earth excavation, construction waste and material stacking may all cause a large amount of dust. Therefore, dust suppression is extremely necessary in the construction environment. A large amount of dust not only affects the visual environment, but may also cause harm to human health. Dust contains many harmful substances, and long-term inhalation may cause respiratory diseases. Among them, fog cannons are a frequently used dust reduction equipment. Fog cannons use high pressure to atomize water into fine water mist particles, and then spray them into the air, combining with dust particles in the air to make them settle. Fog cannons have the characteristics of wide coverage and high dust reduction efficiency, and are suitable for use in large construction sites.
