Information on PVC fluidized bed dryers
Thread Content
I am currently working on PVC fluidized bed drying. Could those of you from Sichuan share some technical parameters and photos of fluidized bed dryers? ! Please! yzqj32@163.com
In the fluidized bed, the bed temperature remains between 50-70 degrees, the temperature of the tube bank is around 65 degrees, and the exhaust air temperature is between 40-60 degrees. There is no localized overheating, the quality is stable, and no quality issues arise
Thank you to the person above first! I assume by tube temperature you mean the temperature inside the tubes. Also, will condensate water flow back if the exhaust temperature is below the dew point temperature?
Connecting one branch of the hot air to the exhaust line can prevent backflow of condensate water. At the same time, the fan airflow matching must be considered. It’s better to have a higher air volume for the exhaust fan.
There are also several different types of structures for fluidized bed dryers! ! For example, with nitrogen and Nirud: the nitrogen version uses a 6-chamber design, while Nirud uses a 2-chamber design. For different forms, their operating parameters also vary greatly! !
