For achieving the above object, the utility model provides a kind of EDI unit protection system, and comprise pure water tank, this pure water tank is connected with EDI topping-up pump by the first pipeline; Described EDI topping-up pump is connected with EDI strainer by second pipe, described EDI strainer is connected with EDI device by the 3rd pipeline, this EDI device is connected with nitrogen-sealed water tank by the 4th pipeline, this nitrogen-sealed water tank is provided with ultrapure water pump by the 5th pipeline, described ultrapure water pump is provided with the 6th pipeline, the 6th pipeline is disposed with reflux line and pipeline network regulation valve; The other end of described reflux line is connected with described pure water tank; Described reflux line is provided with return valve.
After adopting above technical scheme, close pipeline network regulation valve when ultrapure water pump operation, ensure that producing water by the EDI in backflow pipe network to mate with EDI flooding quantity and open pipeline network regulation valve again.When with water spot water, the pressure of ultrapure water pump discharge reduces, be then back to the water yield of pure water tank by reflux line less, now can ensure the water consumption with water spot.When with water spot without water, producing water in nitrogen-sealed water tank can be back to pure water tank by reflux line and then control the liquid level of nitrogen-sealed water tank, and now EDI device is also in the state run continuously.Ensure to run continuously for 24 hours of EDI device, avoid repeating restart and affect water quality.
In order to the operation ensureing that whole device can be good, the top of described pure water tank is provided with the first pure water tank rising pipe, described EDI device is provided with the EDI device rising pipe with EDI device variable valve; Described nitrogen-sealed water tank is arranged the nitrogen-sealed water tank rising pipe with nitrogen-sealed water tank variable valve.
Conveniently overhaul, increase the work-ing life of device, the first pipeline in the utility model, second pipe, the 3rd pipeline, the 4th pipeline and the 5th pipeline are provided with variable valve.
As preferably, the other end of described 6th pipeline is connected with transmission pipeline network.
As preferably, immediately below described pure water tank rising pipe and described nitrogen-sealed water tank rising pipe, be provided with pond.
In order to the operation ensureing that whole device can be good, as preferably, bottom described pure water tank, be provided with the second pure water tank rising pipe, the second pure water tank rising pipe described in this is connected with described first pure water tank rising pipe, and described second pure water tank rising pipe is provided with pure water tank variable valve.
The beneficial effects of the utility model are: the utility model ensures to run continuously for 24 hours of EDI device by the liquid level controlling nitrogen-sealed water tank, and avoid repeating to restart and affecting water quality, system is simple, is easy to maintaining, effectively reduces human cost.
