Performance Introduction

Working principle of multi effect evaporator:

The principle of multi effect evaporator is to use fresh steam to drive the first effect to produce evaporation, and then use the secondary steam generated by the first effect to drive the next effect evaporation, in order to achieve energy conservation.. In order to reduce the consumption of primary steam, the secondary steam generated during production is introduced into two evaporators for heating steam. The secondary steam generated by the two evaporators can also be introduced into three evaporators for heating steam. Each evaporator is called a first effect, and so on. In this way, several evaporators are connected in series to form a multi effect evaporator. Multi effect evaporators have evolved from primitive evaporation kettles to single effect, double effect, three effect, four effect, or more effect evaporators, all aimed at gradually reducing energy consumption. Single effect evaporation consumes 1.1-1.2 tons of steam per ton of water, double effect evaporation consumes 0.6-0.7 tons of steam per ton of water, three effect evaporation consumes 0.37-0.46 tons of steam per ton of water, four effect evaporation consumes 0.3-0.35 tons of steam per ton of water, and five effect evaporation consumes 0.24-0.3 tons of steam per ton of water. The multi effect evaporation system of Kangjinghui Environmental Protection Company often considers recovering the heat from condensed water or secondary steam to achieve energy-saving goals. In wastewater treatment, automatic online cleaning of preheater fouling should also be considered. Multi effect evaporators can adopt various forms such as forced circulation, natural circulation, falling film, rising film, plate evaporator, etc., and can also use multiple combinations to optimize the process flow.
