Internal Heated Fluidized Bed Dryer
Equipment Introduction:
Internal heated fluidized bed is a new drying technology developed on the basis of conventional fluidized bed drying and indirect heating drying. It immerses a tube heat exchanger in the fluidized drying material, and the heat required for material dehydration is provided by both the heat exchanger and the hot air for fluidization.
Working Principle:
The internal heated fluidized bed is divided into the upper and lower bed body, the air distribution plate, the inlet and outlet ports, etc. And its difference from ordinary fluidized bed is that a built-in heat exchanger is set up in the fluidization section of the lower bed body, and the heat source of the heat exchanger can be steam, water or heat transfer oil, etc. Since most of the heat is supplied by a built-in heat exchange device with high heat exchange efficiency, the hot air is mainly used as a power medium for ensuring normal fluidization, and the demanded amount of hot air is greatly reduced than normal fluidized bed dryer.
Applicable Materials:
Adipic acid, methionine, lysine, PVC, ABS, soda ash, refined salt, sodium percarbonate, anhydrous sodium sulphate, potassium chloride, potassium nitrate, ammonium chloride, ammonium nitrate, ammonium sulfate, calcium chloride, calcium hypochlorite, calcium sulfate, granulated porcelain clay, Granulated fertilizer, iron sulfate, potassium carbonate, potassium chlorate, potassium phosphate, potassium tartrate, sludge, sodium hydrogencarbonate, sodium bromide, sodium chlorate, sodium formate PVC, CPE, PC, etc.
