Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices, in particular to a dust suppression device for construction. Background Art

[0002] Dust suppression devices at construction sites, such as enclosure spray dust suppression equipment or enclosure spray dust suppression systems, have multiple functions:

[0003] Reducing dust on construction sites: These dust suppression devices can spray water mist or water to react with dust particles in the air, causing dust particles to combine with moisture; because water mist or water particles are larger than dust particles, they can effectively absorb dust particles, thereby reducing the dust rate on the construction site and reducing environmental pollution caused by dust;

[0004] Protect the environment and the health of surrounding residents: Dust suppression devices can reduce the dispersion of pollutants and reduce the dust content in the air, thereby protecting the health of surrounding residents and reducing the incidence of respiratory diseases;

[0005] Improve construction efficiency: The use of dust suppression devices can effectively reduce dust, thereby reducing interference with the construction process and improving construction efficiency;

[0006] Reduce expenses: Compared with sprinkler trucks, dust suppression devices can save a lot of water; at the same time, they can also reduce cleaning costs, reduce the frequency of dust cleaning, and save manpower and material resources;
