Facing increasingly stringent environmental regulations, the glass industry experiences significant pressure, particularly regarding flue gas treatment and sulfur dioxide (SO₂) emission reduction. The High Specific Surface Area Calcium Hydroxide Desulfurizer (WD-HAD Series), independently developed by Shandong Vanda Environmental Technology Co., Ltd., is becoming the ideal choice for glass enterprises to achieve ultra-low emissions, reduce costs, and enhance efficiency, thanks to its outstanding performance.

Core Advantages: High Specific Surface Area Delivers Exceptional Performance Enhancement

Vanda Tech's core technology lies in its desulfurizer possessing an ultra-high specific surface area (BET: 50-100 m²/g), far exceeding conventional calcium-based products on the market. This characteristic directly translates into multiple significant advantages:

1. Leap in Desulfurization Efficiency, Easily Achieving Ultra-Low Emissions:

    The enormous specific surface area provides a vast number of reactive sites, significantly improving contact and reaction efficiency between the desulfurizer and SO₂. This ensures stable outlet flue gas SO₂ concentrations consistently meet ultra-low emission standards (typically ≤35mg/Nm³).

2. Faster and More Complete Reaction:

    High reactivity ensures efficient desulfurization is completed within shorter residence times. This is especially suitable for the complex operating conditions of glass furnace flue gas, which exhibits a wide temperature variation range (0-430°C), demonstrating excellent adaptability.

3. Reduced Dosage, Directly Lowering Overall Costs by 30%:

    Higher reactivity means less desulfurizer is required to achieve the same desulfurization efficiency. Practical applications show that adopting Vanda's High Specific Surface Area Calcium Hydroxide Desulfurizer significantly reduces operating costs, lowering overall desulfurization costs by approximately 30%. For a typical glass production line, annual direct desulfurization costs can be saved by **1.5 - 2 million RMB**.

4. Excellent Flowability, Ensuring More Stable System Operation:

    The product features excellent flowability, effectively preventing common issues in traditional dry desulfurization such as pipeline blockage and bridging. This ensures long-term stable and reliable operation of the desulfurization system.

5. Environmentally Friendly, High-Value Byproduct:

    * No Wastewater Concerns: The dry process completely avoids the wastewater treatment challenges associated with wet desulfurization.

    * No Additional Carbon Emissions: The process does not generate CO₂.

    * Minimal Temperature Drop: Minimal impact on flue gas temperature is beneficial for subsequent flue gas treatment and stack thermal lift.

    * Easy Byproduct Valorization: The post-reaction desulfurization byproduct has stable composition, making it easier for comprehensive resource utilization (e.g., in building materials).

The Ideal Desulfurization Solution for the Glass Industry

The dry desulfurization process inherently offers advantages such as low construction investment, small footprint, and simple system design. Combined with the exceptional performance of Vanda's High Specific Surface Area Calcium Hydroxide Desulfurizer, it provides a highly competitive solution for glass furnace flue gas treatment:

* Highly Efficient Compliance:
