Description
Technical Field
The utility model belongs to the technical field of recycling, and particularly relates to an extreme water recycling device of an EDI system.
Background
EDI (Electrodeionization) is a pure combination of ion exchange technology, ion exchange membrane technology and ion electromigration technologyWater manufacturing technology. The method combines the electrodialysis technology and the ion exchange technology ingeniously, makes the ions in water move by utilizing the high voltage of the two ends of the electrodes, and cooperates with ion exchange resin and a selective resin film to accelerate the removal of the ions, thereby achieving the aim of water purification. H-enriched output of EDI system 2 The current common treatment is to drain the extreme water directly, which results in a lot of water being wasted, with a conductivity of 50 mus/cm.
Disclosure of Invention
The utility model provides an EDI system polar water recovery device which can recover and reuse polar water and avoid waste of water resources.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an EDI system polar water recovery device comprises an ultrafiltration water tank, a lifting pump, a water valve and a pure water recovery system; the water inlet of the ultrafiltration water tank is connected with the water outlet of the EDI system, and a water valve is arranged at the water outlet of the EDI system and used for controlling the on-off of polar water; the water outlet of the ultrafiltration water tank is connected with a pure water recovery system, and a lifting pump is arranged between the ultrafiltration water tank and the pure water recovery system; the lifting pump is a lifting pump with a liquid level start-stop function, a switch for controlling the on-off of a lifting pump circuit through the liquid level, and the lifting pump can be closed when the liquid level of the water tank does not reach the standard; the ultrafiltration water tank is made of PP material.
The beneficial effects are that: the utility model provides an extreme water recovery device of an EDI system, which is characterized in that extreme water generated by the EDI system is guided into an ultrafiltration water tank and is stored in the ultrafiltration water tank, and then is recovered to a pure water recovery system through a lifting pump, wherein the lifting pump is a liquid level start-stop lifting pump, the on-off switch of a lifting pump circuit is controlled through the liquid level, the lifting pump is closed when the liquid level of the water tank does not reach the standard, the structure is simple, the use is convenient, the safety and the reliability are realized, the lifting pump is closed when the liquid level does not reach the standard, the electricity is saved, and the service life is prolonged; the polar water recovery device can save 4.5 tons of tap water in one hour, can save 3.942 ten thousand tons of water in one year and saves water cost by about 13.79 ten thousand yuan all year round.
Drawings
FIG. 1 is a schematic view of an apparatus for recovering extreme water according to the present utility model.
Detailed Description
The utility model is described in detail below with reference to the attached drawings and the specific embodiments:
as shown in figure 1, the extreme water recovery device of the EDI system comprises an ultrafiltration water tank made of PP material, a lifting pump with a liquid level start-stop function, a water valve and a pure water recovery system; the water inlet of the ultrafiltration water tank made of the PP material is connected with the water outlet of the EDI system, and a water valve is arranged at the water outlet of the EDI system and used for controlling the on-off of polar water; the water outlet of the ultrafiltration water tank is connected with a pure water recovery system, and a lifting pump is arranged between the ultrafiltration water tank and the pure water recovery system; the lifting pump is started and stopped with a liquid level, the on-off switch of a lifting pump circuit is controlled through the liquid level, and the lifting pump can be closed when the liquid level of the water tank does not reach the standard; the ultrafiltration water tank is made of PP material.
When the ultra-filtration water tank is in operation, the polar water generated by the EDI system is introduced into the ultra-filtration water tank, and then is recovered to the pure water recovery system through the lift pump with the liquid level start-stop function, the on-off switch of the lift pump circuit is controlled through the liquid level, and when the liquid level of the water tank does not reach the standard, the lift pump can be closed, and 4.5 tons of tap water can be recovered and saved per hour.
The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
