Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a high-pressure water spray dust removal device suitable for building construction. Background Technology

[0002] During construction, earthwork excavation, material transportation, and concrete mixing generate a large amount of dust, which not only seriously pollutes the construction site environment but also harms the health of construction workers and may even violate environmental regulations. Therefore, high-pressure water jet dust suppression systems, as a highly efficient dust control device, are widely used in construction projects. They achieve dust suppression by atomizing water and combining it with dust particles, making them a key technological tool for ensuring construction safety and environmental compliance.

[0003] Traditional dust suppression systems in construction sites mostly employ fixed or simple adjustable structures. Fixed systems typically have nozzles fixed at a specific height and angle, using a water pump to pressurize and spray water. Simple adjustable systems adjust the nozzle direction manually by rotating or plugging in the nozzle, but the adjustment range is limited. The mechanical structure of these systems relies on fixed supports or single-direction adjustment components, and their technical principle mainly utilizes water pressure to form a water mist, lacking adaptability to complex construction scenarios.

[0004] However, existing dust suppression devices generally suffer from fixed spray angles and heights. Due to the complex terrain and varying working surface heights at construction sites (such as foundation pit excavation and high-rise building construction), traditional devices struggle to flexibly cover different areas, resulting in ineffective dust control and low dust suppression efficiency. Furthermore, a single, fixed spray angle makes it difficult to adapt to changes in wind direction and dust diffusion, further reducing dust suppression effectiveness and failing to meet the dust control needs of diverse construction environments.
