Problems solved by technology

[0002] In thermal power generation, the cooling water of the steam turbine condenser circulating water system is mainly reused after being cooled by the cooling tower in the closed circulating water system, or directly used for one-time use by using water from rivers, rivers, lakes, seas, etc. However, in the hot summer, the circulating water through the above two methods cannot reach the ideal water temperature required by the steam turbine condenser, resulting in poor cooling effect of the condenser and a drop in vacuum, which makes the steam turbine The best driving force cannot be exerted, resulting in high coal consumption; in order to increase the vacuum degree of the steam turbine condenser, the current solution is to run one or more circulating water pumps and vacuum pumps to increase the circulating water volume and air extraction volume , to increase the vacuum degree of the steam turbine condenser
However, these methods have greatly increased the power consumption of the plant, making the cost of power generation high, and it is still difficult to achieve the ideal vacuum degree.

Abstract

The invention provides a method and a device for cooling circulating water in a turbine condenser. The device is mainly composed of a condenser and a circulation refrigerant refrigeration device. Theinvention is characterized in that heat absorbing tubes are arranged in an inlet water chamber of a circulating water system of the condenser, heat dissipating tubes are arranged in an outlet water chamber of the circulating water system of the condenser, the heat absorbing tubes and the heat dissipating tubes are connected by a conduit and a compressor to form the circulation refrigerant refrigeration device, the heat absorbing tubes are used for rapidly refrigerating the circulating water in the inlet water chamber and the heat dissipating tubes are used for rapidly dissipating the heat of the circulating water in the outlet water chamber. The invention solves the problem that higher temperature of the circulating water of the condenser causes the efficiency of the turbine to be reduced,thus being suitable for all the thermal power systems.
