Use
The purged with fresh water operation steps:
1. when being used for purged with fresh water, reverse osmosis seawater desalination system quits work, and F3F, F4, F15, F6, F7 are in closing condition.
2. valve setting: Open valve F1, F2, F8, F9, F12, F14; Valve-off F10, F11.F13 is the by-pass valve control of ultra-fine filter recirculation water, and general recirculation water is the 10-15% of aquifer yield, when opening F12, should grasp valve opening degree, and the control backflow water yield is unsuitable excessive.
3.F15 be in closing condition when flat, when the remote water delivery of needs, just open.
4. so sewage draining valve all is in closing condition when operation, only uses when blowdown or back flushing.
5. open the housing power switch, send to equipment.
6. at first water source submersible pump work is supplied water to raw water box, and about 25min water tank can be filled with water.
7. when water source submersible pump work 10min, the operation water pump can drop into and carry out.After the energising, the operation water pump has been in the frequency conversion working order, and 3 water taps opening left side behind the car are used water, open F11 simultaneously and also can supply water to filtered water tank.
8. when bringing into operation, not up to standard as water quality, can close F11 unlatching F13 and be back to raw water box, water receiving uses again when up to standard.The sea water desaltination operation steps:
1. when being used to desalinize seawater, hollow fiber membrane ultrafiltration device and ultraviolet disinfector 1 are stopped using, and F8, F12, F13, F14, close.
2. valve setting: start or stop valve F1, F2, F3, F4, F5, F7, F9; Valve-off F6, F10, F11;
3.F4 be the dispensing by-pass valve control, during the sea water desalting equipment operation, must open dispensing, chemicals feed pump need be set, and quantitatively adds;
4.F15 the same with purged with fresh water, be in closing condition at ordinary times, when the remote water delivery of needs, just open.
5. so sewage draining valve all is in closing condition when operation, only uses when blowdown or back flushing.
6. open the housing power switch, send to equipment.
7. the submersible pump work of first water source is got seawater and is supplied water to raw water box, about 25min water tank full water.
8. when water source submersible pump work 10min, the operation backwashing pump puts into operation.After the energising, the operation water pump is in running order, can carry through pretreated seawater to high-pressure pump at any time.
9. high-pressure pump requires water inlet to be necessary for malleation, and when process pump high-pressure pump water-in working properly just had been pressed with water, high-pressure pump can put into operation.Special suggestion: under any circumstance high-pressure pump must not anhydrous operation.
10. open dense water throttling valve, start high-pressure pump.Special suggestion: under any circumstance must not close dense water throttling valve and start high-pressure pump.
11. after concentrated stream amount meter, the water outlet of fresh-water flow meter do not have bubble, begin to close dense water throttling valve, adjusting to the rate of recovery of sending out osmosis system water is 30%, promptly begins normal operation.
12. the high-pressure pump shutdown: when seawater desalination system is out of service, slowly open dense water throttling valve, the system operating pressure of making progressively descends, and has suffered journey and is no less than 5 minutes, closes high-pressure pump then.
SS filtering material filter backwash operation step:
1. take out water in the raw water box by process pump, strainer is carried out backwash.
2.2. manual multiple-way valve requires necessary shutdown operation, at first the valve F2 on the process pump rising pipe is closed.
3. open sewage draining valve P2.
4. open valve F2, promptly begin the SS filtering material filter is carried out backwash.
5. when back washing strength is excessive, can adjust by F2 or P2 valve.
6. after backwash finishes, valve-off F2.
More medium filter backwash operation step:
1. more medium filter backwash water is taken from the water that purifies through the SS filtering material filter.
2. open sewage draining valve P11.
3. opening valve F2 more promptly begins more medium filter is carried out backwash.
4. when back washing strength is excessive, can adjust by F2 or P11 valve.
5. after backwash finishes, valve-off F2, P11.
Charcoal filter backwash operation step:
1. charcoal filter backwash water is taken from the water through SS filtering material filter and more medium filter purification.
2. open sewage draining valve P13.
3. open valve F2 again, promptly begin charcoal filter is carried out backwash.
4. when back washing strength is excessive, can adjust by F2 or P13.
5. after backwash finishes, valve-off P13.
6. charcoal filter can reduce the backwash number of times, the every backwash of SS filtering material filter and more medium filter 2 times, back-washable 1 time of charcoal filter.
Accurate filter backwash operation step:
1. accurate filter backwash water is taken from the water that purifies through SS filtering material filter, more medium filter and charcoal filter, and backwash in every month once gets final product.
2. close F5, F8, F9.Open sewage draining valve F6, F7, F9, F15, promptly begin accurate filter is carried out backwash.
3. less because of the accurate filter tank body, wash out precision Filter element when back washing strength is excessive easily, can adjust by the F6 or the P15 control turnover water yield.
4. when flushing when having any problem, accurate filter can be opened, take out precision Filter element and clean dirt, as also available 10% the sulfuric acid of having ready conditions soaked 1 hour, use flushing with clean water then 2 times with hairbrush.Precision Filter element should be changed if any breakage.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
