Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a dust suppression device for building construction. Background Technology

[0002] Spray dust suppression is a novel dust control technology. Its principle is based on the fact that the microparticles generated by the spray are extremely small, with virtually zero surface tension. When sprayed into the air, they quickly adsorb dust particles of various sizes, effectively controlling dust. It is highly effective for dust control over large, open areas. Furthermore, this effect is entirely atomized, producing no water droplets or moisture. It is particularly suitable for widespread application in foundries, textile mills, food factories, printing plants, airports, amusement parks, pedestrian streets, etc., offering significant results at a low cost.

[0003] Existing dust suppression equipment for construction projects still has some shortcomings. Most construction dust suppression equipment has a fixed dust suppression height during use, which cannot be adjusted, and the dust suppression range is fixed, which cannot be adapted to the construction scenario. Therefore, we propose a dust suppression device for construction projects. Utility Model Content
