Submersible dredging barges are highly effective tools for sediment removal in industrial and environmental projects, particularly in challenging environments like seawater sedimentation tanks. This article explores a successful sedimentation tank desilting scheme implemented in Indonesia, highlighting the equipment configuration, operational efficiency, and key considerations for selecting the right submersible dredging barge for your project.
Project Overview: Seawater Sedimentation Tank Cleaning in Indonesia
Client Requirements
The project involved cleaning sludge from seawater sedimentation tanks in Indonesia with the following specifications:
- Sedimentation tank dimensions: 10 meters × 10 meters.
- Sludge depth: 1.5 meters.
- Discharge distance: 300 meters.
- Work environment: Saltwater conditions requiring corrosion-resistant equipment.
The goal was to efficiently remove sludge while minimizing operational downtime and environmental impact.
Tailored Solution: Submersible Dredging Barge Configuration
To meet the client’s needs, Tai’an Ocean Pump Co., Ltd. designed a customized submersible dredging barge system combining a submersible slurry pump, high-pressure water pump, and a floating platform. Below is the detailed configuration:
1. Submersible Slurry Pump: ZJQ360-26-55
This pump was optimized for handling dense sludge with high wear resistance.
Key Specifications:
- Flow rate: 360 m³/h.
- Head: 26 meters.
- Power: 55 KW.
- Speed: 980 rpm.
- Outlet diameter: 150 mm.
- Max particle size: 36 mm.
Custom Modifications:
- Filter-style suction head: Replaced the original agitator impeller and mesh plate to enlarge the inlet and prevent blockages.
- Extended suction head: Improved access to sludge while avoiding large debris ingestion.
- Wear-resistant materials: High-chromium alloy construction for durability in abrasive environments.
2. High-Pressure Water Pump System
Used to fluidize compacted sludge for easier extraction.
Key Specifications:
- Flow rate: 100 m³/h.
- Head: 50 meters.
- Power: 22 KW.
- Outlet diameter: 65 mm.
Function:
- The high-pressure water gun loosened sludge, creating a slurry for the submersible pump to extract.
3. Frequency Conversion Control Platform (G90)
Ensured precise control over pump operations.
Features:
- Variable frequency drive (VFD): Enabled flow rate adjustments via speed control.
- Integrated protection: Safeguarded against overloads and electrical faults.
- User-friendly interface: Simplified operation and monitoring.
4. Custom Floating Platform
Designed to support all equipment while ensuring stability in water.
Design Highlights:
- Buoyancy calculations: Optimized platform size for load distribution and cost efficiency.
- Compact layout: Accommodated the submersible pump, high-pressure water pump, and control system.
Project Results and Client Feedback
Operational Success
- The system achieved continuous sludge removal at 360 m³/h, completing the project within the scheduled timeframe.
- Discharge pressure: Maintained sufficient force to transport sludge 300 meters without clogging.
Client Recommendations
The client provided valuable feedback for future improvements:
- Adjustable suction head angle: To optimize sludge intake in varying tank conditions.
- Enhanced winch brake pad wear resistance: For prolonged durability in high-frequency operations.
These insights were integrated into Tai’an Ocean Pump’s product development, enhancing future submersible dredging barge designs.
Key Considerations for Selecting a Submersible Dredging Barge
When choosing equipment for sedimentation tank desilting, consider the following factors:
1. Sludge Characteristics
- Material type: Fine silt, clay, or abrasive solids.
- Particle size: Ensure pump inlets and impellers can handle maximum debris sizes (e.g., 36 mm in this case).
2. Project Scale and Discharge Requirements
- Tank dimensions: Match pump capacity (flow rate and head) to sludge volume and discharge distance.
- Example: For a 10m×10m tank with 1.5m sludge depth, a 360 m³/h pump is ideal.
3. Environmental Conditions
- Saltwater corrosion: Use anti-corrosion materials like high-chromium alloy.
- Space limitations: Opt for compact floating platforms for confined areas.
4. Customization Needs
- Suction head design: Filter-style heads prevent blockages in debris-heavy environments.
- Control systems: Frequency converters allow real-time adjustments to optimize efficiency.
5. Cost and Maintenance
- Energy efficiency: Variable frequency drives reduce power consumption.
- Wear-resistant components: Minimize downtime and replacement costs.
