The MVR single-effect evaporator has an exceptionally high amount of condensate water – is this normal?
Thread Content
Site situation: As of now, the feed volume is approximately 2850 m3, while the amount of condensate water has reached 9000 m3. The processing capacity is 1 T/D. Due to insufficient water supply at the site, the machine has to be stopped every time 80 m3 of water are processed. The machine has been in operation for 1 year and 5 months. I would like to know whether the amount of condensate water is normal. There are two points that raise concerns for me: First, one of the connections at the upper part of the heater is connected to the hot inlet side of the plate heat exchanger, while the hot outlet side is connected to the vacuum pump; however, the vacuum pump has never been operated. Second, the connection at the lower part of the heater is connected to the condensate tank, and an exhaust port is located at the upper part of this tank. When the MVR is in operation, a large amount of steam can be seen flowing towards this exhaust port. Seeking help to resolve doubts. Seeking help to resolve doubts.
An excessive amount of condensate water is abnormal. There may be issues with heat loss or system leakage. If the vacuum pump is not running, steam may not be effectively removed, resulting in excess condensed water. Additionally, improper connection of the heater to the condensate tank can also lead to heat loss. It is recommended to check the sealing at the system interfaces to ensure there are no leaks, and to examine the operating status of the heater and vacuum pump. .
The vacuum pump has never been used, so why is it included? . .
2800 input and 9000 output – that doesn’t seem normal at all. Where did over 6000 units of water come from out of nowhere? The process water fed into the system is likely to be spray water, along with a small amount of steam; so how much can there be?
The cause has been identified: it’s a problem with the flow meter. The difference between the total inflow and total outflow is only 1,000 m3 of water; there’s an excess of 1,000 m3
Why not run the vacuum pump? By increasing the vacuum level, the evaporation temperature required is reduced, and accordingly, the amount of cooling water needed also decreases
