Fluid Bed Dryer Instead Bulk Solid Heat Exchanger for Potassium Sulphate Processing

Model Number: SV-#3585 Brand Name: SeHenStar Key Specifications/Special Features: The plate type bulk solids heat exchanger is conceptually a very simple piece of equipment. It consists of an inlet hopper, one or more plate banks in parallel and a mass flow device. The product enters in the top,forms a cone above the plates and flows between the equal flows channels in gravity flow. The cooler operates with the product level always maintained above the plate banks. So it operates always full of product. The mass flow device creates equal movement of bulk solids over the whole cross-section of the cooler. Cooling water flows through the plates. A relatively simple level control at the top (not in our scope) generates a 4- 20m Amp signal to control the mass flow device at the bottom in such a way that what comes in at the top leaves at the bottom within maximum and minimum inlet hopper level set points.Features: A. Uses up to 90% less energy. The SV bulk solids heat exchanger is ultra-efficient, using up to 90% less energy than other technologies. The indirect plate cooling design does not require the use of air in the cooling process, which eliminates both the need for large horsepower electric drives and the associated heat losses. B. Zero emission, dust, fines, or odors The indirect plate cooling design means air is not in contact with the product during the cooling process. Emissions, dust, fines and odors are eliminated because air is not used to directly cooling the product. C. Reduced installation costs The indirect plate cooling design means air is not used in the cooling process. Installed capital costs are reduced due to the elimination of costly and unnecessary air handling equipment such as large diameter air ducting, motors, fans, scrubbers, chillers, and emissions controls.
D. Compact & modular-adding future capacity is easy
The vertical configuration makes this design both compact and modular. The clever modular design means that additional heat exchanger plate banks can be stacked if increased cooling capacity is required in the future. The compact installation footprint makes this design easy to integrate in existing plants and is ideal for de-bottlenecking, revamps and capacity increases.

E. Uniform final product temperatures
Mass flow design means the product moves with uniform velocity through the heat exchanger. This feature, combined with long residence times (typically 5-10 minutes), enables even temperature distribution as the product passes through the heat exchanger, producing remarkably stable and uniform final product temperatures.
