Flow Actuation Valve (FAV 100) Dust Suppression System
Overview
The Flow Actuation Valve (FAV 100) Auto Control Dust Suppression System is a high-precision solution designed to control dust during the transfer of raw materials from one conveyor belt to another, specifically at receipt and discharge points. This system ensures dust suppression only when material is actively being transferred, preventing unnecessary water usage and maintaining operational efficiency.
The system is ideal for heavy industrial operations, including coal handling plants, steel plants, cement facilities, and other bulk material handling industries where dust control is critical for safety, environmental compliance, and equipment longevity.
Integrated DSS Variants
a. DFDS – Dry Fog Dust Suppression System
- Operates using compressed air and water, atomized through a twin-port sonic nozzle to create microscopic dry fog droplets.
- Droplets attach to dust particles, causing them to settle back into the material stream.
- Self-cleaning nozzle reduces maintenance needs.
- Applications: Conveyor transfer points
- System Components: FAV-100 mechanical sensing system, sonic atomizing nozzles, air and water lines.
- Benefits: Efficient dust control, minimal water usage, self-cleaning nozzles, and mechanical operation without electronics.
b. PWDS – Plain Water Dust Suppression System
- Uses plain water sprays, often combined with Raingun sprinklers, to control dust over large surfaces.
- Can be integrated with the FAV-100 for automated operation based on material flow.
- Applications: Conveyor transfer points
- System Components: Vertical/Centrifugal pumps, piping, nozzles, control valves, and FAV-100
- Benefits: Wide-area dust control, efficient water usage, and improved environmental compliance.
c. CFDS – Cold Fog Dust Suppression System
- Produces fine cold fog droplets that capture airborne dust particles and return them to the main material stream.
- Integrated with the HMC FAV-100-A for automatic operation based on material flow.
- Applications: Conveyor belts.
- System Components: High Pressure pump unit, RO Treatment plant, cold fog nozzles, piping, and control mechanisms.
- Benefits: Reduces dust emissions, enhances workplace safety, and optimizes water consumption.
Key Features
- Automatic Operation Based on Material Flow: Sprays activate only during conveyor operation and material transfer; no spraying occurs when the belt is loaded but stationary or during no-load running conditions.
- Mechanically Operated Sensing Unit: The sensing mechanism is 100% mechanical, spring-loaded, and activated by the material weight, eliminating the need for electrical or electronic components.
- Hydraulic Pump and Control Valve: Integrated inbuilt hydraulic pump unit with control valve for precise water regulation.
- Compact and Easy Installation: Designed for mounting below the conveyor belt with minimal modifications.
- Durable Construction: Built to withstand industrial environments and operate reliably under varying water pressures.
- Water-Saving Design: Activates spraying only when needed, reducing water consumption and minimizing wetting of conveyor belts.
System Components
- Spring-loaded mechanical sensing unit
- Base frame fixture for stable installation
