Recently, the State Environmental Protection Department announced the "steel industry pollution prevention BAT guidelines - sintering and pelletizing process" (draft), SDA desulfurization process Danmainilu cooperation with our company is included in the desulfurization most BAT can be applied to all domestic scale sintering machine desulfurization.

SDA technology uses lime (CaO) as the absorbent, quick lime slaked lime slurry was formed after digestion (Ca (OH) 2), by pumping slaked lime slurry to the top of the absorber rotary atomizer, atomizer wheel speed rotation effect at After the slurry is atomized into hundreds of millions of droplets, untreated hot flue gas into the absorber, immediate contact with the droplet was strongly alkaline absorber, the flue gas acid components (HCl, HF, SO2 , SO3) is absorbed, while the water droplet is evaporated into the dry desulfurization products.

The main features of SDA process is high reliability, the system is simple to operate and good elasticity, fast response, low total investment, no corrosion. With the growing importance of environmental protection, is expected in 2009 various domestic steel mills will increase investment in environmental protection, the Group will strive to Jiangsu 峘 this advanced technology to more sintering desulfurization practice for environmental state contribute to a cause.
