Working principle: the technical program is a kind of scheme about chemical water manufacturing system, and scheme is interior by entire chemistry water System Partition becomes 4 subsystems, and the whole automatic control of chemical water manufacturing system is realized by the automatic control of 4 subsystems System；4 subsystems are respectively treating nature water device, ultrafiltration apparatus, reverse osmosis unit and ion demineralizer, now to every height Device control mode does following explanation.

Treating nature water device includes raw water water pump, reaction settling basin, air scrubbing filter, chemical pond, fire water Pond and circulating water pool, when chemical pond, fire cistern, circulating water pool liquidometer detect that a certain pond liquid level drops to setting liquid Position, program controlled automatic open water replenishment door, and treating nature water device starts automatically, and control system first is by reaction settling basin and sky Gas is cleaned each valve in filter tank and is adjusted to operating status, and then program controlled automatic starting raw water water pump, which slowly promotes frequency, makes to react Sedimentation basin operating load slowly rises, and reaction settling basin load starts raw water medicine system and basis automatically when going up to 50t/h Reaction settling basin operating load adjustment dosing pump running frequency ensures that treating nature water system effluent quality is qualified, raw water water pump Operating load is automatically adjusted according to chemical pond, fire cistern and circulating water pool liquid level, chemical pond, fire cistern and Circulating water pool liquid level after attaining to a high place each water replenishment door close treating nature water system and be automatically stopped operation.

Ultrafiltration apparatus automatic running is that interlocked control is carried out by ultrafiltration high water tank, and runing time is arranged in each ultrafiltration apparatus When ultrafiltration high water tank reaches a certain setting value, control system is accumulated according to runing time and ultrafiltration high water tank is automatic for accumulation The selection operation lesser ultrafiltration apparatus of accumulated time puts into operation, as ultrafiltration high water tank continues to decline ultrafiltration control system root The alternative condition that puts into operation on accordingly continues to put into other not running ultrafiltration apparatus until ultrafiltration high water tank starts to go up, ultrafiltration water tank After liquid level goes up to a certain setting value ultrafiltration apparatus will according to runing time accumulate selection the longer ultrafiltration apparatus of runing time into Row is stopped transport, and will continue to stop transport other according to the above stoppage in transit alternative condition as ultrafiltration high water tank continues to rise ultrafiltration control system Ultrafiltration is run until ultrafiltration apparatus all automatic stoppages in transit.

Reverse osmosis unit automatic running is that interlocked control is carried out by fresh-water tank liquid level, when each reverse osmosis unit setting is run Between accumulation when fresh-water tank liquid level reaches a certain setting value control system according to runing time accumulate and fresh-water tank liquid level select automatically It selects the operation lesser reverse osmosis unit of accumulated time to put into operation and interlock and automatically engage antisludging agent dosing pump, such as fresh-water tank liquid level Continue to decline reverse osmosis control system will be continued to put into other not running reverse osmosis units according to the alternative condition that puts into operation above it is straight Start to go up to fresh-water tank liquid level, reverse osmosis control system will be according to runing time after going up to a certain setting value for fresh-water tank liquid level The accumulation selection longer reverse osmosis unit of runing time is stopped transport, as fresh-water tank liquid level continues to the reverse osmosis control system that goes up To be continued to stop transport according to the above stoppage in transit alternative condition, other operations are reverse osmosis until reverse osmosis unit is all automatic stops transport.

Ion demineralizer automatic running is that interlocked control is carried out by sweet-water tank liquid level, each ion demineralizer setting Runing time accumulation control system when sweet-water tank liquid level reaches a certain setting value is accumulated according to runing time and sweet-water tank Liquid level automatically select operation the lesser ion demineralizer of accumulated time put into operation, as sweet-water tank liquid level continue to decline from Sub- desalination control system continues to put into other not running ion demineralizers until sweet-water tank liquid level according to condition selected above Start to go up, ion demineralizer will accumulate selection operation according to runing time after sweet-water tank liquid level goes up to a certain setting value Time, longer ion demineralizer was stopped transport, as sweet-water tank liquid level continues to rise ion desalination control system for basis Condition selected above continues to stop transport other operation ion demineralizers until all automatic stoppages in transit of ion demineralizer.

Product demineralized water supply user is rising in main-piping pressure decline of confessing that main-piping pressure controlled according to demineralized water It confesses pump operation frequency more than demineralized water after setting value to increase automatically, main-piping pressure, which goes up, confesses pump more than demineralized water after setting value Running frequency reduces automatically.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
