Mostly use pond to cool down the circulating water of underground coal mine, etc. water temperatures increase to a certain extent after, equipment will call the police shutdown,
Heat exchange efficiency is low and is unfavorable for the continuous operation of equipment.It is for the mining area that water is more sufficient, then the recirculated water after heat exchange is straight
Run in out, lead to the waste of water resource, while also needing special messenger's controlled valve, and wastes artificial.
Utility model content
The purpose of the utility model is to overcome above-mentioned prior art problem, provide that a kind of heat exchange efficiency is high, discharge is less
Circulating water cooling system.
The technical scheme in the invention for solving the above technical problem is: a kind of circulating water cooling system, comprising: interior
Portion's circulating cooling system, outer loop cooling system, PLC controller, the internal circulating cooling system includes water tank, recirculated water
The inner loop pipeline of pump, the cooler for cooling down thermal medium, air-cooled type heat exchanger and each equipment of connection, outer loop
Cooling system includes feeding spraying pump, external circulation line, and air-cooled type heat exchanger includes blower, and inner circulating tube road is provided with flow
It counts, is provided with high-temperature medium import, cryogenic media outlet, temperature sensor, circulating water intake, circulating water outlet on cooler,
PLC controller is provided between temperature sensor and water circulating pump, feeding spraying pump, blower, PLC controller uses signal wire respectively
It is connect with water circulating pump, feeding spraying pump, blower.
Further, the flow be calculated as electromagnetic flowmeter, it can be achieved that on the spot display and transporting function.
Further, the inner loop pipeline can pressure-bearing 4.0MPa, the external circulation line can pressure-bearing 1.6MPa.
Further, the water circulating pump is wear-resisting centrifugal multistage pump multiple centrifugal pump.
Further, the feeding spraying pump is one step single sucking clear water centrifugal pump.
Further, the water tank is assembled water tank.
Utility model has the advantages that 1) start-stop of the circulating water cooling system is automatically controlled using temperature sensor,
Replace artificial inspection, operation with automation, saves manual resource；2) recirculated water flows into after being exchanged heat by air-cooled type heat exchanger
Recirculated water is evacuated in cooler by water circulating pump by assembled water tank later, can prevent the waste of water resource.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples, but is not intended to limit the present utility model.
Referring to Fig. 1, a kind of circulating water cooling system, comprising: internal circulating cooling system 1, outer loop cooling system 2,
PLC controller 3；Internal circulating cooling system 1 includes water tank 11, water circulating pump 12, cooler 13, wind for cooling down thermal medium
The inner loop pipeline 15 of cold type heat exchanger 14 and each equipment of connection；Outer loop cooling system 2 include feeding spraying pump 21,
External circulation line 22；Air-cooled type heat exchanger includes blower 141；Flowmeter 151 is provided on inner loop pipeline 15.
Further, be provided on cooler high-temperature medium import 131, cryogenic media outlet 132, temperature sensor 133,
Circulating water intake 134, circulating water outlet 135, temperature sensor 131 and water circulating pump 12, feeding spraying pump 21, blower 141 it
Between be provided with PLC controller 3；PLC controller 3 is connect with signal wire with water circulating pump 12, feeding spraying pump 21, blower 141 respectively.
Specifically, one section of logic control program is incorporated into PLC controller 3, when the temperature of the high-temperature medium in cooler
When higher than setting value, electric signal is passed to PLC controller 3 by temperature sensor 131, PLC controller 3 after logic calculation,
It is judged to opening water circulating pump 12, feeding spraying pump 21 and blower 141, starts to provide cooling water into cooler 13.
Further, water circulating pump 12 is wear-resisting centrifugal multistage pump multiple centrifugal pump.
Further, feeding spraying pump 21 is one step single sucking clear water centrifugal pump.
Further, water tank 11 used in the utility model is assembled water tank, is transported in underground coal mine more convenient.
