A vacuum pumping problem
Thread Content
The existing equipment operates at a pressure of 1 KPA (absolute pressure), with a water vapor flow rate of 2000 kg/h. It’s not possible to use a vacuum pump for this purpose – it’s too large. I hope experienced colleagues can help me out
If there is only water vapor and no non-condensable gases, the problem is simple: a mixed condenser will suffice, one with a diameter of ∮800 is adequate. Along with it, a cooling tower with a capacity of 150–200 tons is needed, and it’s easy to determine the flow rate and head required for the circulation pump.
Large capacity, low vacuum； It is recommended to use a water ring vacuum pump, and the vacuum level should be controlled
