This case study examines a highly efficient denitrification powder pneumatic conveying system deployed in Phan Thiet, Vietnam. The system was designed and implemented by Shandong Haide Powder Engineering Co., Ltd., a leading provider of advanced pneumatic conveying solutions. The project focused on delivering a reliable and cost-effective negative pressure injection pneumatic conveying system for the precise handling of denitrification powder in a local industrial facility. By leveraging cutting-edge technology, the system ensures consistent material flow, minimal dust emission, and low maintenance requirements, making it an ideal choice for environmental compliance and operational efficiency.
The denitrification powder pneumatic conveying system at the Phan Thiet site operates on a negative pressure principle, where a vacuum pump creates a pressure differential to draw the powder through a sealed pipeline. This method is particularly suitable for fine, abrasive, and hygroscopic materials like denitrification powder, as it prevents leakage and contamination. The system includes a receiving hopper, a rotary valve feeder, a conveying line, a cyclone separator, and a bag filter. The negative pressure injection pneumatic conveying technology ensures that the powder is injected directly into the reaction chamber with precise dosing control, optimizing the denitrification process. The entire setup is automated, with sensors and PLC controllers monitoring parameters such as pressure, flow rate, and material level, allowing for real-time adjustments and remote monitoring.
One of the primary benefits of the negative pressure injection pneumatic conveying system is its ability to handle materials without degradation. The low-velocity, high-density flow minimizes particle breakage, preserving the chemical properties of the denitrification powder. Additionally, the sealed system eliminates dust leakage, ensuring a clean and safe working environment. The negative pressure design also reduces the risk of material bridging or clogging, which is common in positive pressure systems when dealing with sticky powders. The Vietnam pneumatic conveying market has seen growing demand for such systems due to their energy efficiency, compact footprint, and ease of integration with existing processes. The Phan Thiet installation has demonstrated a 20% reduction in energy consumption compared to traditional mechanical conveyors, while achieving a 99.5% material transfer efficiency.
Denitrification powder is widely used in industrial boilers, cement kilns, and waste incineration plants to reduce nitrogen oxide (NOx) emissions. The denitrification powder pneumatic conveying system ensures that the powder is delivered accurately and consistently to the injection point, where it reacts with flue gases to convert NOx into harmless nitrogen and water. The negative pressure injection pneumatic conveying technique allows for precise control over the injection rate, which is critical for meeting emission standards without overdosing. In the Phan Thiet project, the system was tailored to handle a throughput of 5 tons per hour, with a conveying distance of 120 meters and a vertical lift of 15 meters. The system operates 24/7, with minimal downtime for maintenance, thanks to the robust design and high-quality components supplied by Shandong Haide Powder Engineering Co., Ltd.
The Vietnam pneumatic conveying system in Phan Thiet features a vacuum pump with a capacity of 15 kW, a conveying line of DN80 stainless steel pipe, and a control system with touchscreen interface. The system was customized to accommodate the specific particle size distribution (100–200 mesh) and bulk density (0.8 g/cm³) of the denitrification powder. The negative pressure injection pneumatic conveying system also includes a nitrogen purge mechanism to prevent powder accumulation in the filter. All components are manufactured in accordance with international standards, ensuring durability and safety. The system has been operating successfully since commissioning, with a reported availability rate of over 98%.
