Functional Experience & Measured Results

Waste Incinerator Flue Gas Desulfurization

Testing scenario & pain point: The plant previously used baking soda, which had high consumption (18-20kg per ton of waste), unstable SO₂ emissions, and high operational costs. Actual usage & testing process: The desulfurizer was injected into the reaction tower at a calcium-sulfur ratio of 1.3, with real-time monitoring of SO₂ concentration. Real experience & results: SO₂ concentration stabilized at ≤35mg/Nm³, meeting national and local standards, with fluctuation controlled within ±5mg/Nm³ even when waste components changed. Desulfurizer consumption dropped to 6kg per ton of waste, a 67% reduction compared to baking soda. Solved pain points: Reduced operational costs by over 50%, eliminated emission overrun risks, and reduced equipment corrosion caused by excessive spraying.

Multi-Pollutant Collaborative Treatment

Testing scenario & pain point: The plant faced risks of dioxin and heavy metal exceeding standards, with large amounts of hazardous by-products. Actual usage & testing process: The desulfurizer was used in combination with activated carbon and SCR systems to monitor multi-pollutant removal effects. Real experience & results: HCl and HF removal rates reached 92% and 88% respectively, particulate matter stabilized at ≤10mg/m³, and dioxin emissions met EU standards. The by-product contained only 4.2% unreacted Ca(OH)₂, with high-purity calcium sulfate that could be sold as building materials. Solved pain points: Eliminated secondary pollution risks, reduced hazardous waste disposal costs, and achieved multi-pollutant collaborative governance.

Pros & Cons

Core Advantages 1. Ultra-high desulfurization efficiency and stability: Maintains consistent performance even with fluctuating flue gas components, eliminating emission overrun risks. 2. Significant operational cost reduction: Cuts desulfurizer consumption by over 60%, reducing overall maintenance and material costs. 3. Environmentally friendly by-product recycling: Produces non-hazardous by-products that can be reused, reducing waste disposal costs and carbon emissions. Real Disadvantages 1. Moisture-sensitive storage: The desulfurizer’s activity decreases if exposed to moisture, requiring sealed packaging and dry storage conditions. 2. Slightly reduced activity at low temperatures: Activity drops by around 5% at temperatures below 40℃, suggesting a heating device for low-temperature scenarios.

Target Users & Scenarios

This product is ideal for: - Waste incineration, steel, coking, and cement enterprises requiring ultra-low flue gas emission compliance - Users seeking to reduce desulfurization operational costs and achieve by-product recycling - Facilities with flue gas temperatures between 40-430℃ It is not recommended for: - Small workshops without moisture-proof storage conditions - Scenarios requiring flue gas treatment at temperatures below 40℃ without supporting heating equipment - Users needing laboratory-grade ultra-high purity desulfurizers.
