Trench is directly discharged into, water resource waste is caused and is caused desalination water manufacturing system producing water ratio low.Therefore, EDI devices are rinsed and is arranged
Water system is changed, and improves desalination controlling the water circulation producing water ratio, is reduced water resource waste and is significant.
Utility model content：
The purpose of this utility model is for above weak point, there is provided a kind of EDI flush discharges reuse structure, structure letter
It is single, reasonable in design, effectively reduce water resource waste.
This utility model solves the scheme that adopted of technical problem, a kind of EDI flush discharges reuse structure, including reverse osmosis
Thoroughly device, intermediate water tank and EDI devices, connect between the reverse osmosis unit and intermediate water tank via reverse osmosis produced water pipe,
Connect via EDI water inlet pipes between the intermediate water tank and EDI devices, flush discharge pipe is connected with the EDI devices, it is described
Flush discharge pipe is connected via reuse pipe with reverse osmosis produced water pipe, enters middle with the flush discharge of sharp EDI devices start-up course
Water tank is recycled.
Further, it is provided with the first regulating valve on above-mentioned flush discharge pipe.
Further, above-mentioned reuse pipe is disposed with the first check valve and the second regulating valve along water body reuse direction.
Further, above-mentioned flush discharge pipe is respectively connected with the blow-off pipe with the 3rd regulating valve, the blowdown with reuse pipe
Pipe is connected with gutter.
Further, the second list that reverse osmosis unit is back to anti-water-stop body is provided with above-mentioned reverse osmosis produced water pipe
To valve.
Compared with prior art, this utility model has the advantages that：This utility model is reasonable in design, EDI devices
Flush discharge merge with reverse osmosis produced water pipe via reuse pipe, injection intermediate water tank be circulated utilization, can not only improve and remove
Salt controlling the water circulation producing water ratio, and the waste of water resource can be reduced.

Specific embodiment:
With reference to the accompanying drawings and detailed description the utility model is described in more detail.
As shown in figure 1, a kind of EDI flush discharges reuse structure of this utility model, including reverse osmosis unit 1, intermediate water tank 2
And EDI devices 3, connect via reverse osmosis produced water pipe 4 between the reverse osmosis unit 1 and intermediate water tank 2, the intermediate water tank
Connect via EDI water inlet pipes 5 between 2 and EDI devices 3, flush discharge pipe 6, the row of flushing are connected with the EDI devices 3
Water pipe 6 is connected via reuse pipe 7 with reverse osmosis produced water pipe 4, and with the flush discharge of the sharp start-up course of EDI devices 3 middle water is entered
Case 2 is recycled, i.e., reverse osmosis unit 1 injects water body in intermediate water tank 2, in intermediate water tank 2 via reverse osmosis produced water pipe 4
Water body enters EDI devices 3 via EDI water inlet pipes 5 again, and EDI devices 3 are processed water body, produces water Jing EDI water producing pipes 16 and enters
Sweet-water tank 15；When EDI devices 3 just put into, first flush discharge 5min～20min or so rinses the water body discharged and flows successively
Jing flush discharges pipe 6, reuse pipe 7 and the injection intermediate water tank 2 of reverse osmosis produced water pipe 4, then reenter via EDI water inlet pipes 5
In EDI devices 3, realize recycling, not only improve desalination controlling the water circulation producing water ratio, and reduce water resource waste.
In the present embodiment, the first regulating valve 8 is provided with the flush discharge pipe 6, the reuse pipe 7 is along water body reuse side
To the regulating valve 10 of check valve 9 and second is disposed with, it is easy to control the flush discharge work of EDI devices 3.
In the present embodiment, the flush discharge pipe 6 is respectively connected with the blow-off pipe 11 with the 3rd regulating valve 14 with reuse pipe 7,
The blow-off pipe 11 is connected with gutter 12, is easy to clean and blowdown EDI devices 3.
In the present embodiment, first check valve 9 is non-return valve, and the product water for preventing reverse osmosis unit 1 is produced to EDI devices 3
Raw impact, affects the normal work of EDI devices.
In the present embodiment, first regulating valve 8 is Pneumatic butterfly valve, and the second regulating valve 10 and the 3rd regulating valve 14 are handss
