The evaporator is used for sewage treatment
According to the energy conservation theorem, the amount of steam consumed by the processor evaporates 1t of water: single effect 1.1, double effect 0.57, three effect 0.4, four effect 0.3, five effect 0.27.
This is followed by the use of the previous effect of secondary steam as the next effective evaporator heat source.
Evaporator for sewage treatment In the first evaporator with direct steam heating, the secondary steam generated by the heated liquid boils into the second evaporator as the heat source, which is the second-effect evaporation.
