working principle：

 

In large scale industrial production, it is often necessary to evaporate a lot of water, which requires a lot of energy to heat water to produce steam. In order to reduce the consumption of heating steam, multi effect evaporation can be used. The heating steam is passed into an evaporator, the solution is heated and boiled, and the two steam pressure and the temperature are lower than the original heating steam (i.e., the steam), but the two steam can still manage to be used. In the multi effect evaporation, the secondary steam as the heating steam and introducing another evaporator, as long as the evaporation chamber pressure and boiling point of the solution were compared to the original evaporator is low, is the introduction of the secondary steam can play a role in the heat. In the same way, the two new steam generated by the second evaporator can be used as the heating steam of the third evaporator. In this way, each evaporator is known as an effect, and the plurality of the evaporator are connected together to form a multi effect evaporation system. Adding the evaporator of the raw steam as the first effect, the first effect of the two steam heating is known as the second effect, and so on. The utilization of heat energy, which is used for recycling and reusing, significantly reduces the consumption of heat energy, which greatly reduces the cost and increases the efficiency.

 

Main features:

 

1. The evaporator is connected with the operation, and the two steam generated during the evaporation of the first evaporator is used as the heating steam of the evaporator.

 

2, repeated use of thermal energy, significantly reduce the amount of energy consumption. 

Traditional evaporator main types: single effect evaporator, double effect evaporator, triple effect evaporator, four effect evaporator, five effect evaporator.

 

Application range:

 

Multi effect evaporator is widely used in medicine, food, chemical industry, light industry and other industries of water or solution evaporation and concentration, and can be widely used in industrial wastewater treatment. Multi effect evaporator has many advantages, such as high evaporation capacity, energy saving, low cost of operation and so on.
