How to remove moisture from 2000 m3/h of air?
Thread Content
The Roots blower supplies air to the production system at a rate of 2000–2500 m3/h. The outlet pressure of the Roots blower is 20 KPa. Now, it is necessary to remove the moisture from the air. How can this be achieved? Is there any equipment large enough to handle this task?
What is the dew point temperature now? The last heat-pump dryer?
The freeze-dryer attached to the air compressor can solve this issue. I don’t know much about this; the heat-drying machine mentioned above might be more suitable
Like us, I have a centrifugal fan here; its air volume is 2400 m3/h and the pressure is 9 kPa. At the moment, I plan to install a freeze-dryer
Everyone is right; to remove moisture with such a high airflow rate, it is generally necessary to cool the air so that the water in it condenses, and then separate it out to achieve dry air.
I’ve also done some inquiries on this; a freeze-dryer is needed. The key question is whether it’s capable of handling such a high volume of air flow, and if so, what efficiency can be achieved. What is the power of the cold dryer? If it’s not proportional, wouldn’t that be a waste?
It seems that the refrigeration dryer used with the compressor has a relatively high pressure loss
42 m3 (under pressure)/min – it can’t be said to be a volume that’s too large to handle. // Using cold drying, only a relatively small reduction in the pressure dew point can be achieved； It is recommended to use dryers with adiabatic regeneration or mild heat regeneration~~~~ In the Jiangsu and Zhejiang regions, especially around Hangzhou, there are many manufacturers~~
To what extent is the moisture removed? What is the required water dew point?
This requires communication with the equipment manufacturer; we don’t have any data on this aspect at the moment. The lower the moisture content, the better.
