1. Product Overview<\/span><\/p>\n

High-Efficiency Acidic Pollutant Removal<\/h2>\n

\uadf8\ub9cc\ud07c BLDJ1W-100W Series Single-Alkali Desulfurization System<\/strong> is a state-of-the-art environmental protection equipment designed to rapidly neutralize and remove sulfur dioxide (SO2<\/sub>) and other acidic pollutants from industrial flue gas. Utilizing sodium hydroxide (NaOH) or sodium carbonate (Na2<\/sub>CO3<\/sub>) as the primary liquid absorbent, this system guarantees exceptionally fast reaction kinetics and zero internal scaling.<\/p>\n

As a highly cost-effective and structurally optimized solution, the BLDJ Series serves as a perfect, budget-friendly replacement for premium Western models such as the Babcock & Wilcox or Duerr Megtec wet scrubber systems. It matches their desulfurization efficiency (exceeding 95%) while drastically reducing initial capital expenditure and ongoing maintenance costs.<\/p>\n

\ud575\uc2ec \uacbd\uc7c1\ub825 \uc694\uc57d:<\/strong> Extremely rapid gas-liquid absorption, zero risk of gypsum scaling inside the tower, high desulfurization efficiency even under fluctuating loads, and a highly compact footprint designed for both new installations and retrofits.<\/p>\n<\/div>\n

3. Process Chemistry<\/span><\/p>\n

\uc791\ub3d9 \uc6d0\ub9ac<\/h2>\n

Single alkali desulfurization (sodium alkali method) removes acidic pollutants by reacting an alkaline absorbent with SO2<\/sub> in the flue gas. The process takes place in the Core Reaction Zone of the absorption tower, ensuring maximum gas-liquid contact time.<\/p>\n<\/div>\n

\n
\n

Step 1: Flue Gas Absorption<\/h3>\n

As the hot flue gas ascends through the tower, it intersects with the atomized liquid droplets. The sulfur dioxide dissolves rapidly into the water to form sulfurous acid.<\/p>\n

SO2<\/sub> + H2<\/sub>O \u2194 H2<\/sub>SO3<\/sub><\/span><\/p>\n<\/div>\n

\n

Step 2: Main Neutralization<\/h3>\n

Taking NaOH as the initial absorbent, the sulfurous acid reacts instantaneously with the sodium hydroxide to form sodium sulfite and water. This is the primary desulfurization mechanism.<\/p>\n

\uc2dc\uac042<\/sub>SO3<\/sub> + 2NaOH = Na2<\/sub>SO3<\/sub> + 2H2<\/sub>O<\/span><\/p>\n<\/div>\n

\n

Step 3: Saturation Reaction<\/h3>\n

If the SO2<\/sub> concentration in the flue gas is in excess, the newly formed sodium sulfite will further react with the acid to form sodium bisulfite.<\/p>\n

\uc2dc\uac042<\/sub>SO3<\/sub> + Na2<\/sub>SO3<\/sub> = 2NaHSO3<\/sub><\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n

4. Key Benefits<\/span><\/p>\n

Five Core Advantages<\/h2>\n<\/div>\n
\n
\n
\ud83d\ude80<\/div>\n

1. Ultra-Fast Reaction Kinetics<\/h3>\n

Sodium-based alkalis possess exceptional solubility and alkalinity. The gas-liquid mass transfer rate is significantly faster than calcium-based systems, ensuring rapid SO2<\/sub> absorption.<\/p>\n<\/div>\n

\n
\ud83d\udee1<\/div>\n

2. Zero Tower Scaling<\/h3>\n

Because the reaction products (sodium sulfite\/bisulfite) are highly soluble in water, there is absolutely no risk of solid precipitation or scaling clogging the spray nozzles or tower internals.<\/p>\n<\/div>\n

3. High Efficiency<\/h3>\n

Routinely achieves over 95% desulfurization efficiency, effortlessly meeting the strict <35 mg\/Nm\u00b3 ultra-low emission standards required by modern environmental regulations.<\/p>\n<\/div>\n

\n

4. Compact Footprint<\/h3>\n

The high reactivity allows for a smaller tower volume and a lower liquid-to-gas ratio. This reduces the footprint, making it ideal for retrofitting older plants with limited space.<\/p>\n<\/div>\n

5. Lower CapEx<\/h3>\n

The simplified slurry preparation and lack of complex solid-handling equipment dramatically lower the initial capital expenditure compared to double-alkali or limestone-gypsum systems.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

5. Structural Engineering<\/span><\/p>\n

System Mix & Materials<\/h2>\n

The BLDJ Series is fabricated using highly anti-corrosive materials. The main tower shell typically utilizes carbon steel lined with heavy-duty glass flake epoxy or high-grade FRP (Fiberglass Reinforced Plastic) to withstand the acidic environment.<\/p>\n
