Multiple Evaporator

Multi-effect evaporator: The heat released by the condensation of one kilogram of steam is basically the same as the heat absorbed by the evaporation of one kilogram of water, so for single-effect evaporation, one kilogram of water in the evaporated material needs to consume one kilogram of new steam ; If the secondary steam obtained by evaporation is used as the heating steam of the next effect, the energy consumption of the second effect steam and the new steam will be saved by 50% compared with the single effect. The number of effects increases and the use of steam decreases, but the investment in equipment increases a lot, so generally it does not exceed 5 effects.
