In winter, the fog cannon use of attention

Many people should have seen fog cannons by now, especially fog cannon trucks are very common in cities. The fog cannon is an important equipment to deal with urban environmental problems nowadays. The rear part of the dust suppression vehicle that removes haze and reduces dust from city streets is the main body of the fog cannon. The fog cannon is atomized by high-pressure water into water droplets comparable to the size of dust. Since the water droplet particles are similar or identical to the dust particles, the dust particles become wet by contact with the water droplet particles during operation with the airflow. The wet dust particles continue to adsorb other dust particles and gradually form particle clusters  which sink due to their own weight increase.
