Desulfurization sludge dewatering process: in the clean water tank by a certain program solvent by adding sodium hydroxide and calcium hydroxide, through the delivery device and the boiler flue gas SO2 and CO2 reaction in the desulfurization equipment to produce a water-insoluble calcium sulfite, calcium sulfate and calcium carbonate, and the flue gas mixed with flue ash, along with the inflow sedimentation tanks, the use of horizontal spiral centrifuge discharge settlement (the decanter centrifuge) for solid-liquid separation of sludge and slag containing solid rate of more than 70 percent, cake recycling, such as the system of an internal combustion brick, cement and other system, clear liquid into the reaction cell recycling.

The decanter centrifuge features:

Bowl, spiral and other selected acid-resistant special stainless steel high chloride using advanced technology painstakingly created, screw the outer edge of tungsten carbide inserts, high strength wear-resistant alloy block, wear resistance, corrosion resistance, advanced technology, reasonable structure, long life, low noise.
