Description
Technical Field
The invention belongs to the technical field of water vapor recovery equipment for electrode aluminum foil production, and particularly relates to a water vapor recovery system of a circulating water cooling tower.
Background
In the production process of the electrode aluminum foil for the aluminum electrolytic capacitor, a production line uses a large number of heat exchangers for temperature control. The exchanger uses a large amount of soft water to cool, and the used soft water can be recovered and recycled for the production line after being cooled by the cooling tower. Companies currently have multiple open cooling towers that utilize countercurrent contact of soft water with air to exchange heat, thereby removing heat from the soft water. In the process of taking away heat, a large amount of water vapor with high temperature and part of soft water are emitted into the atmosphere, and the water vapor is liquefied into water mist when meeting cold in the rising process. From a distance, the tower mouth image discharges a lot of white smoke, so that people around the tower mistakenly think the tower is industrial waste gas, and the tower often complains, thereby causing serious adverse effects on the image of an enterprise. On the other hand, a large amount of soft water is emitted into the atmosphere, causing loss of the soft water, increasing the production cost.
