SDA Rotating Spray Process

Process for the spray drying absorption (SDA) based on a simple concept, through years of careful research into advanced precise and effective system. Untreated flue gas into Rotary spray absorption tower immediately after being atomized alkaline slurry (usually Hydrated lime) to acid components in the flue gas (HCL, HF, SO2, SO3) is absorbed by the alkaline spray at the same time transformed into a fine powder. To enhance the effect of mercury and dioxin, can be injected in the flue gas activated carbon. Some fly ash and products from the bottom of the tower being emitted. Have already been processed flue gas continue to the dust collector, remove remaining suspended particles in the filter through the chimney flue gas is cleaned.

Rotate the spray process works are simultaneously using the spray dryer absorption and drying process. Key to achieving these two important device is rotating atomizer and flue gas distributor. Former feed slurry atomization into millions of small droplets, which ensure the accurate distribution of flue gas drying and reaction conditions to achieve the best. Rotary atomizer can run 2000 hour continuous and does not require any maintenance.

Features

1, designed specifically for municipal solid waste incinerator

2, Denmark with hydro technologies, supporting the atomizer GEA companies, advanced technology

3, the desulphurized product can be used again, and no secondary pollution

4, SDA process according to the flue gas flow rate, thermometer changes automatically adjusted

5, no need to set the bypass, keep furnace conditions can easily replace the atomizer
