Design Philosophy
Our product is designed with the core principles of high efficiency, environmental friendliness, low cost, and stability, fully considering harsh industrial working conditions and adhering to full-life-cycle reliability standards to provide customers with stable, low-maintenance, cost-effective solutions .
Technical Principles
The core working principle of High-Surface-Area Hydrated Lime is based on acid-base neutralization reaction between calcium-based materials and acidic gases. The complete implementation process is as follows:
1. High-reactivity hydrated lime comes into contact with acidic gases such as SO₂, HCl, and HF in flue gas, initiating rapid neutralization reactions .
2. Stable by-products such as calcium sulfate are generated, which can be recycled for resource utilization, eliminating secondary pollution .
Core Architecture & Innovative Design
We have optimized the product structure with two key innovative modules:
1. Raw Material Activation Module: Enhances the specific surface area and reactivity of hydrated lime through a proprietary process, ensuring full contact with flue gas .
2. Reaction Optimization Module: Ensures complete reaction of materials, reducing unreacted components to ≤5% and improving resource utilization efficiency .
Comparison with Traditional Solutions
Compared to traditional lime desulfurization products, our technology achieves key breakthroughs:
1. Traditional products have low reactivity, requiring large dosages; our product maintains a calcium-sulfur ratio of 1.2-1.5, reducing material consumption by 20-40% .
2. Traditional by-products are difficult to dispose of; our by-products have high purity and can be reused as building materials or soil conditioners, reducing solid waste disposal costs .
