Core Technical Advantages

1. Integrated Oxidation and Cooling Technology

The Red Lead Granular Lead Oxide Moving Bed innovatively adopts a moving bed structure, integrating the oxidation and cooling processes into one. After the granular red lead completes a continuous deep oxidation reaction inside the bed, it directly enters the cooling zone for rapid cooling, avoiding secondary contamination and performance loss that may occur during intermediate transfer. By precisely controlling the bed temperature and material residence time, we effectively solve the industry problems of temperature gradients and incomplete reactions in large-scale production, ensuring uniform oxidation and consistent particle morphology.

2. Gas-Solid Countercurrent Contact Process

The equipment adopts a gas-solid countercurrent contact design, where the fluid and granular material flow in opposite directions, significantly increasing the gas-solid contact area and reaction efficiency. This results in a more complete oxidation reaction of the granular red lead and a significant improvement in product purity. Simultaneously, this process reduces energy consumption during the reaction. Combined with a sealed operation design, it not only reduces the risk of lead dust and lead vapor leakage but also further improves raw material utilization and reduces production waste.

3. Intelligent Temperature Control and Sealing Technology

Our Red Lead Granular Lead Oxide Moving Bed is equipped with high-precision thermocouples and an intelligent temperature control system. This system monitors the temperature of each area of the bed in real time and automatically adjusts the supply of hot and cold air according to the reaction progress, ensuring the reaction temperature remains stable within a reasonable range. This prevents materials from melting and clumping due to excessively high temperatures, or from affecting the oxidation effect due to excessively low temperatures. Simultaneously, the equipment's inlet and outlet adopt a driven sealing structure, with the sealing cover opened and closed by a cylinder. This ensures convenient operation and strong sealing, completely eliminating lead dust and lead vapor pollution, meeting environmental protection production requirements.

4. Modular Structure Design

The equipment adopts a modular design, allowing for independent installation and maintenance of units such as the light oil combustion furnace, oxidation moving bed, cooling moving bed, and bag filter. This significantly reduces equipment maintenance difficulty and downtime. The modules are tightly integrated, allowing for flexible adjustment of production capacity according to user needs, adapting to different production scales, and possessing strong versatility and scalability.
