The utility model relates to an automatic device for recycling high-purity water in a nitrogen-sealed water tank, which realizes the recovery of the high-purity water in the nitrogen-sealed water tank, and more particularly, the high-purity water in the nitrogen-sealed water tank always needs to overflow in the nitrogen sealing device to ensure that the air in the nitrogen-sealed water tank is isolated.
In order to solve the problems existing in the prior art and overcome the defects thereof and realize the aim of avoiding serious waste of high-purity water, the utility model adopts the following technical scheme:
as shown in FIG. 1, in the high-purity water saving and recycling device, a self-priming water pump 2 is arranged in a water tank 1, and the self-priming water pump 2 is connected with a secondary water tank 5 through a drainage pipeline 4.
The utility model can change the original overflow into collection and reuse, thereby saving a great amount of water resources. To the serious waste of pure water equipment high-purity water in the industry at present, through retrieving collection device, collect high-purity water, let originally the high-purity water that flows away can obtain collecting through collection device, rethread automatic control is introduced second grade water tank 5 to obtain the recycle, has solved the waste problem of high-purity water completely, has accomplished the recycling moreover.
