Device for heating in winter by using industrial circulating water

The utility model discloses a device using industrial circulating water for heating in winter, which comprises a cooling tower, a water outlet of the cooling tower is connected with a heat exchanger through a connecting pipe, the heat exchanger is connected with one end of a water supply pipe, and generated condensate water is pumped into the cooling tower through a fourth water pumping assembly. Water heated by the heat exchanger is pumped into the heat preservation water tank through the first water pumping assembly to be collected, water in the heat preservation water tank is pumped out through the second water pumping assembly to enter a heating area, and then the water is pumped into the cooling tower again through the third water pumping assembly to achieve circulation. Meanwhile, cold water in the cooling tower is pumped into the heat exchanger through the connecting pipe by utilizing the first water pumping assembly and exchanges heat with factory circulating water, the heated water is discharged into
