Condensate tank configuration
Thread Content
A vacuum evaporation unit has been installed, with an evaporation capacity of around 200 L/h and a vacuum level of -60 kPa. Now a vacuum pump needs to be purchased. Questions: 1. What type of vacuum pump is suitable for these conditions (taking into account the presence of water vapor)? 2. Should the vacuum pump be connected directly to the condensate tank, or should a vacuum tank be used as an intermediate buffer?
We use a steam jet pump to draw it from the main pipe at the top of the device
A vacuum buffer tank should be installed to help protect the vacuum pump. If the water evaporated contains no organic substances, a water ring vacuum pump can be used.
It seems that it’s rather troublesome to connect water to a water ring vacuum pump; are there any smaller models recommended?
Vertical oil-free vacuum pumps, or the older W-type models, are easy to maintain.
A condenser is installed at the outlet of the evaporator; the top of the condenser is connected to a water-ring vacuum pump, or a steam jet pump can also be used.
