Powder cooling
Thread Content
How can powders be cooled conveniently and quickly? We mainly deal with catalyst powders, which come out of the furnace at a temperature of around 400 degrees.
Enter the fluidized bed and be cooled by air, resulting in a relatively uniform distribution
It mainly depends on what special physical properties the catalyst we have has – can it react when exposed to air? In the pharmaceutical industry, I’ve seen fluidized bed systems being used
It cools down quickly too when exposed to air!
As I understand it, that small amount of catalyst fed into the fluidized bed isn’t enough to be consumed, right? In terms of practical production solutions, it’s not that easy.
What are the requirements, and what are the capabilities needed? Cooling the fluidized bed directly with air? This will remove some moisture, having a drying effect; is there any impact? There is the direct cooling method, and then there is indirect cooling. The material does not come into contact with the medium; heat exchange is achieved through stainless steel. There are many other ways as well; the choice depends on your specific requirements. Simply put, it can cool down on its own; the problem is either that the process is too slow or that continuous production is needed to send the material to the storage tanks downstream. It’s necessary to have a clear explanation before considering how to solve it.
There is a device called a powder cooler, and it’s quite good.
