Will a boiling fluidized bed dryer used for sodium sulfate drying experience dead bed?
Thread Content
I would like to consult the experts: our company is currently working on a sodium sulfate project, and we have doubts regarding the selection of drying equipment. Will a bubbling fluidized bed dryer used for drying sodium sulfate cause a dead bed condition? :handshake:handshake:handshake
Pretty much! Sulfuric acid an absorbs moisture very readily! What should I do about parking?
Compared to vibration fluidized bed drying? Is it easier to die in a bed dryer, or is vibrating fluidized bed drying not suitable for drying sodium sulfate?
Vibrating fluidized beds can be used to dry sodium sulfate; moreover, since most sodium sulfate contains Cl ions in its composition, many drying devices have high maintenance costs, whereas with vibrating fluidized beds, only the bed plates need to be replaced
Actually, the chlorine level is very low during drying, so it’s usable.
Controlling the wind speed and the fluidization velocity of the sieve plates prevents a dead bed from forming. To control the wind speed, it is necessary to regulate the thickness of the material layer and its moisture content. Relatively speaking, the volume in a bubbling bed is larger, while a vibrating bed reaches its limits in terms of drying capacity at a certain point.

Thank you:handshake
Definitely, defects on the finished product are closely related to the previous processing steps and the quality of the workers. For drying sodium sulfate in my project, I usually use a vibrating fluidized bed
