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

Advanced Spray Drying Absorption (SDA)<\/h2>\n

De BLSDA1W\/230W Series Semi-Dry Desulfurization System<\/strong> is a mainstream, highly efficient alternative to traditional high-energy, high-water-consumption wet scrubbing processes. It relies on the precise injection of an atomized alkaline slurry (typically lime) directly into high-temperature flue gas.<\/p>\n

This advanced technology achieves rapid moisture evaporation and drying simultaneously with gas-liquid-solid three-phase acid-base neutralization. Acidic sulfur oxides and halides in the flue gas are instantly converted into dry, solid salts.<\/p>\n

Engineered as a high-ROI, seamless replacement for premium European models (such as the Alstom\/GE SDA systems or Babcock & Wilcox spray dry absorbers), the BLSDA Series achieves desulfurization efficiencies exceeding 95%<\/strong>. Its defining advantage is that no massive wastewater treatment facility is required<\/strong>, making it economically and environmentally superior.<\/p>\n<\/div>\n

3. Reaction Mechanism<\/span><\/p>\n

Three-Phase Synergistic Control<\/h2>\n

The core principle relies on the contact between an atomized alkaline slurry (lime) and high-temperature flue gas (140-220\u00b0C). It neutralizes sulfur oxides and completely dries the reaction products before they can hit the chamber walls.<\/p>\n<\/div>\n

\n
\n

Main SO2<\/sub> Neutralization<\/h3>\n

The calcium hydroxide slurry atomizes into micro-droplets, creating a massive surface area that instantly absorbs and neutralizes sulfur dioxide into calcium sulfite.<\/p>\n

\n

Sulfur Trioxide (SO3<\/sub>) Removal<\/h3>\n

A small amount of SO3<\/sub> present in the flue gas is simultaneously neutralized, forming stable calcium sulfate dihydrate and preventing highly corrosive acid mist.<\/p>\n

\n

Halide (HCl & HF) Removal<\/h3>\n

Common in waste incineration and kiln flue gases, hydrogen chloride and hydrogen fluoride are absorbed and converted into solid salts that solidify upon droplet drying.<\/p>\n

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

Five Unmatched Engineering Advantages<\/h2>\n<\/div>\n
\n
\n

1. Zero Wastewater Discharge<\/h3>\n

The absolute biggest advantage over wet scrubbers. The liquid phase completely evaporates, leaving only dry powder. No massive water treatment facilities are needed.<\/p>\n<\/div>\n

\n

2. Exceptional Efficiency<\/h3>\n

High-speed rotary atomizers create 60\u03bcm droplets, maximizing the gas-liquid contact area to routinely exceed 95 percent SO2<\/sub> removal.<\/p>\n<\/div>\n

\n

3. Multi-Pollutant Control<\/h3>\n

Synergistically captures SO2<\/sub>, SO3<\/sub>, HCl, HF, and heavy metals within a single reactor pass, streamlining your plant’s emission control strategy.<\/p>\n<\/div>\n

\n

4. No Plume Generation<\/h3>\n

Because the exhaust gas exits at a temperature well above the dew point, the system operates completely free of the visible white vapor plume typical of wet systems.<\/p>\n<\/div>\n

\n

5. Lower CapEx & Maintenance<\/h3>\n

Constructed primarily from carbon steel (avoiding expensive high-nickel alloys). It eliminates the need for complex slurry dewatering equipment like hydrocyclones.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

5. System Architecture<\/span><\/p>\n

System Composition & Process<\/h2>\n

The BLSDA system integrates thermal dynamics with precision atomization. The structural layout ensures that unreacted slurry droplets do not touch the inner walls of the chamber.<\/p>\n
