Recirculated water mainly has both modes：One kind is open type cooling, i.e., recirculated water directly reaches technological requirement by the way that cooling tower is air-cooled；
Another kind is enclosed cooling, i.e. recirculated water hands over (heat-exchangers of the plate type) to carry out heat exchange with refrigerant by plate, and the cooling of refrigerant is then
It is air-cooled or be directly that the chilled water that comes of refrigerator conveying is used as refrigerant by cooling tower.First way applies in general to pair
Water quality water temperature requires not high operating mode.The second way is suitable for, water temperature high to water quality requirement and requires high operating mode.Traditional
The secondary side of enclosed cooling, i.e. this side of recirculated water, from workshop back water pump when, be all first to be back to water tank, pressure is down to 0bar, so
Taken away again by water pump afterwards, the main function of water tank is to provide convenience for water treatment medicine, blowdown here, while is also whole
System water supplement guarantee.Such as agent-feeding treatment [J] light science and technologies of recirculated water, 2008,24 (9):115-116. just use this side
Formula carries out the dosing of recirculated water.But its defect is also very notable, and the presence of water tank causes pressure of return water to be reduced to 0bar, and system does not have
Back pressure, causes water pump to do many work(more, while water tank is not completely closed, it is directly contacted with air, this can influence water quality,
Water treatment medicine dosage is caused to increase, blowdown flow rate also increases.
The content of the invention
The purpose of this utility model is exactly to provide that a kind of energy consumption is low, row to overcome the problems of the above-mentioned prior art
The dirty process cycles water utilization system for reducing pump consumption less, stable, the degree of automation is high.
The purpose of this utility model can be achieved through the following technical solutions：
It is a kind of to reduce the process cycles water utilization system of pump consumption, including heat exchanger, it is connected to heat exchanger primary side
Refrigerant unit and the circulation water unit for being connected to heat exchanger secondary side, the circulation water unit include water circulating pump and use water

Recirculated water is back to water circulating pump by water return pipeline, and constant pressure making up water mechanism and medicating mechanism are connected with water return pipeline.
Preferably, the water return pipeline is equipped with blow valve.
Preferably, which further includes controller, the pressure of return water sensor for detecting water return pipeline pressure and is used for
Detect the pressure of supply water sensor of water supply pipe pressure, the constant pressure making up water mechanism, pressure of return water sensor and pressure of supply water
Sensor is connected with controller, and the controller is used for what is detected in pressure of supply water sensor and pressure of return water sensor
When pressure differential reaches preset value, start constant pressure making up water mechanism and carry out moisturizing.
Preferably, the refrigerant unit includes cooling tower, buffer tank and cooling water pump, the cooling tower, buffering
Water tank and cooling water pump export to a side-entrance from the primary side of heat exchanger and set gradually.
Preferably, which further includes temperature sensor, and the secondary side that the temperature sensor is arranged on heat exchanger goes out
At mouthful, and temperature sensor and cooling water pump are connected with controller by cable communication respectively.
Preferably, the heat exchanger is heat-exchangers of the plate type.
Compared with prior art, the utility model has the advantages that：
(1) system causes recirculated water pressure of return water not to be released to 0, as back pressure water pump can be done work less, reach
Energy-saving purpose.
(2) increase constant pressure making up water mechanism on water return pipeline collector pipe, not only provide a system to safety guarantee, while
Provide safeguard to water circulating pump stable operation.
(3) the heat exchanger secondary side of the system is changed into closed system completely, and recirculated water is contactless with air, and water quality compares it
Before greatly improve so that the dosage of water process greatly reduces, while blowdown flow rate is also greatly reduced.
(4) by setting controller and pressure of return water sensor and pressure of supply water sensor, in system leak can and
When be automatically replenished, while also provide certain pressure compensation to water return pipeline so that backwater back pressure is stablized.
(5) when temperature sensor detects that heat exchanger secondary side outlet temperature is excessive, can be increased by controller cold
But water flow, so that circulating water temperature reaches requirement.
