多效蒸馏水机的工作原理
  多效蒸馏水机的流程如下：原料水在一效预热器被工业蒸汽加热，进入以后各效预热器被二次蒸汽继续加热；到冷凝器被二次蒸汽、蒸馏水加热；然后在蒸发器顶部经分水装置，均匀地分布进入蒸发列管，在蒸发列管内形成薄膜状的水流；这些水流因为薄所以很快被蒸发，产生二次蒸汽；未被蒸发的原料水被输送到下一效，作为次效蒸发器的原料水，以后各效与此类似，未被蒸发的进入下一效，直到后一效仍未被蒸发的，将作为凝结水排放；被蒸发的原料水，现在是二次蒸汽，继续在蒸发器中盘旋上升，经中上部特殊分离装置处，进入纯蒸汽管路，作为次效的热源；二次蒸汽在次效被吸收热量后凝结成蒸馏水；各效过程与此相似，各效的蒸馏水和末效的二次蒸汽被冷凝器收集，并经过与冷却水、原料水换热，冷却成为蒸馏水；经过电导率的在线检测，合格的蒸馏水作为注射用水输出，不合格的蒸馏水将被排放。
原料水转化成的二次蒸汽是洁净蒸汽，它经过三次分离作用：在初进入蒸发器后，沿列管向下流动，同时蒸发，这是次分离；被蒸发的原料水（二次蒸汽）在蒸发器的下端180度折返，杂质在重力作用下，被分离到下部，这是第二次分离；被蒸发的原料水，即二次蒸汽，继续在蒸发器中盘旋上升，到中上部特殊分离装置处，进行第三次分离。冷却水只在冷凝器通过，对各效产生的蒸馏水和末效的二次蒸汽进行降温。工业蒸汽在效的蒸发器和预热器对原料水进行加热，热量被吸收后成为凝结水排出机外。在冷凝器中，有一种不能凝结成水的一部分气体，被称作不凝性气体，此部分气体将由安装在冷凝器上部的排出装置去除。根据机型的不同，在各效蒸发器上也可能设有不凝气体连续排放装置。

Working principle of multi - effect distilled water machine

The process of the multi-effect distilled water machine is as follows: the raw water is heated by the industrial steam in the primary effect preheater, and each effect preheater is further heated by the secondary steam after entering the primary effect preheater. The condenser is heated by secondary steam and distilled water. Then the evaporator top is distributed evenly into the evaporator column tube, forming a thin film of water flow in the evaporator column tube. The water is so thin that it quickly evaporates, producing secondary steam; The raw water that has not been evaporated is transported to the next effect, as the raw water of the secondary effect evaporator, and the subsequent effects are similar. The evaporated raw water, now the secondary steam, continues to spiral up in the evaporator, through the middle and upper special separation device, into the pure steam pipeline, as a secondary heat source; The secondary steam condenses into distilled water after the secondary heat is absorbed. Each effect process is similar, each effect of distilled water and final effect of secondary steam is collected by the condenser, and after heat exchange with cooling water and raw water, cooling into distilled water. After online measurement of electrical conductivity, qualified distilled water is output as injection water, and unqualified distilled water will be discharged.

The secondary steam transformed by the raw water is clean steam, which passes through three separations. After entering the evaporator, it flows down the column tube and evaporates at the same time, which is the secondary separation. The evaporated raw water (secondary steam) returns 180 degrees at the lower end of the evaporator. Under the action of gravity, the impurities are separated to the lower part, which is the second separation. The evaporated raw water, the secondary steam, continues to spiral up in the evaporator to the middle and upper special separation device for the third separation. The cooling water only passes through the condenser to cool the distilled water and the final steam produced by each effect. The industrial steam heats the raw water in the efficient evaporator and preheater. The heat is absorbed and the condensed water is discharged out of the machine. In the condenser, there is a part of the gas that cannot condense into water, called non-condensable gas, which will be removed by the discharge device installed above the condenser. Depending on the type of evaporator, the non-condensable gas discharge device may be provided on each type of evaporator.
