During the production process at a coking enterprise in Bijie, Guizhou, coke powder as a by-product requires safe and efficient conveying and transfer. Since coke powder is a flammable and explosive dust, traditional open conveying methods carry risks such as high explosion risk, severe dust escape, and high equipment maintenance costs. A certain company (hereinafter referred to as the enterprise) faces dual pressures in the sealed conveying process of coke powder for both production safety and environmental standards, urgently needing a reliable explosion-proof sealed conveying system.

Customer pain points

The company's original conveyor system had the following obvious shortcomings:
1. Dust explosion risk: Coke powder particles are fine and easily suspended. During transport, they mix with air to the explosion limit, and exposure to open flames or static electricity can trigger explosions.
2. Environmental pollution: Open transportation leads to large amounts of coke powder leakage, with PM2.5 concentrations in workshops severely exceeding standards, posing high occupational health risks for employees, and making it difficult to pass environmental inspections.
3. Low conveying efficiency: Traditional equipment has poor sealing, high material loss, frequent pipe blockages, and maintenance shutdowns, affecting overall production rhythm.
4. Low level of automation: Relying on manual operation and inspection, making remote monitoring and fault warning difficult and presenting management blind spots.

Solutions and product advantages

To address these pain points, Head Powder customized a complete set of explosion-proof sealed conveying coke powder for the company. The system centers on fully enclosed pipeline conveying, combined with explosion-proof design and intelligent control, achieving dust-free and automated operation from raw material receipt to delivery to the terminal.

Key features include:

1.Explosion-proof structural design: The pipeline uses pressure-resistant, anti-static materials, equipped with explosion relief devices and flame arresters, physically eliminating explosion conditions and meeting relevant explosion-proof standards.
2.Completely sealed with no leaks: All connection points in the system use high-efficiency sealing technology, ensuring zero coke powder leakage during operation, meeting workshop clean production requirements and helping enterprises pass environmental inspections.
3.Low energy consumption and efficient conveying: Adopts pneumatic conveying principles, optimizing pipeline layout and power parameters to reduce conveying energy consumption by about 15%, while avoiding pipe blockages and improving continuity and stability of conveying.
4.Intelligent operation and maintenance platform: Integrates multiple types of sensors such as pressure, temperature, and flow to monitor system status in real time; Equipped with PLC control systems, supporting remote start-stop, fault self-diagnosis, and data recording, reducing manual intervention and improving management efficiency.

Project Results

After the project was put into use, the company's coke powder conveying process achieved an intrinsic safety upgrade. Dust concentration detection data consistently stays below safety thresholds, significantly improving the workshop environment; Conveying efficiency has increased by 20% compared to before, reducing material loss by about 50 tons annually; Intelligent operations and maintenance reduce sudden downtime by 80% and overall O&M costs by 30%. This case provides replicable experience for the safe transport of similar flammable and explosive powder materials.
