Refer to Fig. 2, Fig. 2 be first embodiment of the invention disclose the structural representation of circulating water cooling system.Described circulating water cooling system 100 comprises cooling tower 11, water circulating pump 12, heat exchanger 13, control valve 14, water-supply-pipe 150, water supply line (non-label) and water return pipeline 16.Described water supply line and described water return pipeline 16 are arranged in parallel.Described heat exchanger 13 is connected in described water supply line.Described cooling tower 11 comprises circulating water outlet 1131 and recirculated water entrance 1111.Recirculated water flows out from described circulating water outlet 1131, and be back to described recirculated water entrance 1111 respectively by described water supply line and water return pipeline 16 and enter described cooling tower 11, namely wherein a part of recirculated water is first back to described cooling tower 11 again after described water supply line flows through described heat exchanger 13, and another part recirculated water is directly back to described cooling tower 11 from described water return pipeline 16.
Particularly, described cooling tower 11 comprises tower body 111, blower fan 112 and collecting-tank 113.Described blower fan 112 is located at above described tower body 111, and described collecting-tank 113 is located at below described tower body 111.Described recirculated water entrance 1111 is arranged on described tower body 111, and described circulating water outlet 1131 is arranged on described collecting-tank 113.Described tower body 111 comprises spray equipment 1112, packing layer 1113 and air inlet 1114 from top to bottom successively.Described spray equipment 1112 comprises sparge pipe 1123 and is located at multiple nozzles 1124 of described sparge pipe 1123.Described blower fan 112 top is provided with air outlet 1121.
Described water supply line comprises the first flow pipe 151 and the second flow pipe 152.
Be linked in sequence successively described water-supply-pipe 150, water circulating pump 12, first flow pipe 151, heat exchanger 13, second flow pipe 152 and sparge pipe 1123 of described circulating water outlet 1131 forms the first loop.
Described water return pipeline 16 two ends are connected with described first flow pipe 151 and sparge pipe 1123 respectively by three-way connection (non-label), form second servo loop.
Described control valve 14 is connected in described water return pipeline 16, for controlling the circulating water flow by described water return pipeline 16.Preferably, described control valve 14 is intelligent control valve.
The operation principle of described circulating cooling system 100 is: recirculated water flows out from the circulating water outlet 1131 of described cooling tower 11, wherein a part of recirculated water (being defined as recirculated cooling water) enters described cooling tower 11 by described first loop backflow, and another part recirculated water (being defined as backflow cooling water) enters described cooling tower 11 by described second servo loop backflow.In described first loop, heat up after this component loops water accepts the heat exchange of described heat exchanger 13 and become hot water, and the recirculated water in described second servo loop is cold water, the two converges before entering described cooling tower 11 in described sparge pipe 1123, thus the recirculated water average temperature entering described cooling tower 11 is reduced, namely the inflow temperature of described cooling tower 11 reduces, after described recirculated cooling water and backflow cooling water enter described cooling tower 11, described packing layer 1113 is evenly sprayed at by the nozzle 1124 on described sparge pipe 1123, there is heat exchange with described packing layer 1113 to cool, described blower fan 112 forces air to enter described tower body 111 from described air inlet 1114 simultaneously, with recirculated water adverse current by described packing layer 1113, and discharge from described air outlet 1121, recirculated water contacts with air, component loops water is by carburation by evaporation, take away amount of heat, and the cooling effect of described packing layer 1113, circulating water temperature reduces gradually, finally fall in described collecting-tank 113.
After recirculated water falls described collecting-tank 113, the overwhelming majority again as recirculated cooling water for cooling described heat exchanger 13, sub-fraction recirculated water is directly admitted to the spray equipment 1112 of described cooling tower 11, mix with the recirculated cooling water entering described cooling tower 11, again cool in described cooling tower 11.

When separate component loops water as described backflow cooling water after, namely implement backflow cooling means after, the stable leaving water temperature setting described cooling tower 11 is t
3(unit: DEG C, all the other temperature units are same).Before implementing backflow cooling means, the inflow temperature setting described cooling tower 11 is t
1, leaving water temperature is t
2.Through the flow q value of described backflow cooling water select excellent after temperature corresponding to determined q value be t
3, and t
3< t
2.When the leaving water temperature of described cooling tower 11 is with t
3run, removing hear rate, enter the temperature of described heat exchanger 13 lower than the temperature before backflow cooling means, its corresponding process safety water yield, is assumed to be Q
2, namely the flow of described recirculated cooling water becomes Q
2, the operational factor of described circulating water cooling system 100 carries out corresponding change, supposes that running total Water is Q
3, now Q
3< Q
0.
When the flow of inlet water of described cooling tower 11 is changed to Q
3time, redefine q value by q value debugging defining method.
Circulation like this, under the prerequisite meeting the total energy-saving of described circulating water cooling system 100, finds the best q value of described backflow cooling water and the optimum value Q of described cooling tower 11 inflow
3(suppose that the described cooling tower inflow after each change is Q
3).
