[0050] When the environmental dust suppression device for construction is used, the dust suppression device is first assembled and connected to the battery 46 for power supply test operation. After completion, the dust suppression device is moved to the site where it is needed, and the photovoltaic panel 43 is used to receive external sunlight, and the light energy is converted into electrical energy for energy storage.

When the construction site needs to be sterilized and disinfected, the sterilization and disinfectant can be poured into the water storage tank 4, and the reduction motor 9 is started for stirring, and the sterilization and disinfectant is sprayed out to achieve sterilization and disinfection. Therefore, the combination of multi-functional modules can effectively improve the practicability of the dust reduction device and realize the function of one machine with multiple uses.
