The core design principle of the dust removal system is to collect dust locally and treat it centrally, achieving efficient dust capture and purification through optimized airflow organization. This principle requires precise control at the dust generation source while ensuring the pneumatic conveying efficiency of the entire system. Specific implementation must consider process feasibility, space utilization, and operational economy, forming a complete closed loop from source control to end-of-pipe treatment.
Installation Location: The system should be installed directly above or to the side of each processing piece of equipment, within a range of 1.5-2.0 times the equipment height, ensuring coverage of the main dust-generating areas. For high-dust-generating equipment such as sanders and sawing machines, a sealed dust collection hood design is recommended.
Hood Vent Velocity: Based on the dust generation characteristics of the equipment, the designed hood vent velocity should be controlled within the range of 0.5-1.2 m/s. The upper limit should be used for fine dust (particle size <50 μm), while the value can be appropriately reduced for coarse dust.
Structural form: It is recommended to use a tapered dust collection hood with a contraction angle of ≤60°. The ratio of hood length to opening area is recommended to be 3:1-5:1 to form a stable negative pressure field.
