Optimized Dust Collection Pipeline Layout for Wood Processing Facility
1. Introduction
This case study examines the redesign and implementation of an industrial dust collection pipeline network at a high-volume wood processing plant in Sweden. The project addressed critical challenges in airflow efficiency, fire safety, and maintenance accessibility while complying with stringent EU ATEX and ISO 21940-2 vibration standards. The new system serves 48 woodworking machines across a 12,000m² facility with a total airflow capacity of 85,000 CFM.
Key Objectives
- Achieve ≤15 m/s transport velocity for optimal particulate conveyance
- Reduce pressure drop by 35% compared to legacy system
- Implement explosion-proof measures for combustible wood dust (Kst >200 bar·m/s)
