Technical Field

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

[0002] Dust removal systems for construction projects are specifically designed to reduce dust pollution on construction sites. These devices not only effectively lower dust concentrations within and around the construction site, reducing air pollution, but also minimize damage to construction equipment, extending its lifespan and improving efficiency. For modern construction sites, dust removal is not only essential for reducing environmental pollution but also a crucial tool for improving efficiency and protecting worker health.
