Fluid Bed Dryer With Built-In Heat Exchanger
Description
Internal heated fluid bed dryer is a new drying technology developed on the basis of traditional fluid bed dryer by indirect heating drying.
Working Principle
The internal heated fluid beddryeris divided into the upper and lower bed body, the air distribution plate, the inlet and outlet ports, etc. And its difference from ordinary fluid beddryeris 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 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 fluid bed dryer.
Characteristics
1. Efficiency in energy saving is high. Most heat is provided by the in-bed heat exchanger with the efficiency about 90%, hot air is used mainly to ensure normal fluidization, the quantity of hot air is much less than that needed by conventional fluid beddryer; power consumption and heat losses of the exhaust air are accordingly reduced, resulting in higher drying efficiency.
2. As gas flow velocity in the system is lower than that in the conventional fluid beddryer, so the material being entrained from the fluid beddryerby the air is reduced significantly, the load of the dedusting system is reduced and the environmental protection is improved correspondingly.
3. Use of a special air distributor to prevent material leaking.
4. Easy to install, simple to operate, inexpensive to maintain.
5. Integration of drying and cooling bed, small floor space, low investment.
