Abstract
The utility model relates to a turbonator-based cooling water treatment system comprising a boiler, a turbonator and a steam condenser, wherein the boiler, the turbonator and the steam condenser are connected in order. The turbonator-based cooling water treatment system is mainly and technically characterized in that a heat exchanger is arranged between the steam condenser and the boiler. The steam condenser is used for converting steam generated by the turbonator into cooling water and then conveying the cooling water to the evaporator of a heat pump system. Low-temperature cooling water outputted by the evaporator is conveyed to the steam condenser again. Meanwhile, the evaporator is connected with the condenser by a heat pump set. High-temperature water generated by the condenser is conveyed to the heat exchanger, and then high-temperature water outputted by the heat exchanger is returned to the boiler to be recycled and reutilized. According to the technical scheme of the utility model, the heat pump system is adopted instead of an original cooling tower, so that neither heat nor water is discharged to the atmosphere. Therefore, a great amount of energy is saved. Meanwhile, the heat exchanger is additionally arranged ahead the water inlet of the boiler, so that the water inlet temperature of the boiler is improved. In addition, the fuel consumption of the boiler is reduced and the production cost is lowered.
