Technical Field

[0001] The utility model relates to the technical field of water supply systems, in particular to a condenser cooling water supply system. Background Art

[0002] Under normal circumstances, all the steam generated by the steam turbine of a thermal power plant is condensed into water through the condenser and then supplied to the boiler for use; in winter, most of the steam generated by the steam turbine of a thermal power plant is supplied to the heating network through external heating pipes for centralized heating in the city, and a small part of the steam is condensed into water through the condenser and then supplied to the boiler for use; this results in a reduction in the steam flowing through the condenser; at this time, the temperature of the cooling water supplied by the cooling water supply system of the condenser still remains at the original temperature and cannot be adjusted, which often causes the circulating water to freeze and even causes equipment to be damaged. Utility Model Content

[0003] The main purpose of the utility model is to provide a condenser cooling water supply system to solve the problem in the prior art that the temperature of the cooling water supplied by the cooling water supply system cannot be adjusted.

[0005] Furthermore, a regulating valve is provided on the bypass pipe.

[0006] Furthermore, the water supply pipe includes a main pipe connected to an inner pipe and an outer pipe; both the inner pipe and the outer pipe are provided with nozzles for spraying water onto the filler; the nozzle on the outer pipe is located outside the inner pipe.

[0007] Furthermore, a gate valve is provided on the main pipe to control the connection and disconnection between the main pipe and the inner pipe and the outer pipe.

[0008] Furthermore, the condenser is connected to a steam turbine via a pipeline.

[0009] Furthermore, a circulation pump is provided on the circulation pipe.

[0010] The utility model provides a water inlet pipe and a bypass pipe, so that in winter a part of the circulating water can be controlled to pass through the filler to dissipate heat, while the other part of the circulating water does not pass through the filler and does not dissipate heat, thereby adjusting the temperature of the circulating water; by providing a regulating valve, the ratio of the water that dissipates heat and the water that does not dissipate heat can be adjusted; by providing an inner pipe, an outer pipe and a gate valve, the circulating water can be controlled to enter the inner pipe or the outer pipe, or to enter the outer pipe and the inner pipe at the same time.

[0015] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] like Figures 1 to 2 As shown, according to an embodiment of the present invention, a condenser cooling water supply system is provided, including a cooling tower 1 and a condenser 2. The cooling tower 1 is provided with a packing 101 and a water supply pipe 102 for supplying water to the top of the packing 101, and a return water chamber 103 is provided below the water supply pipe 102; the return water chamber 103 is connected to the condenser 2 through a circulation pipe 3, and a circulation pump 8 is provided on the circulation pipe 3; the condenser 2 is connected to an inlet pipe 5 and a bypass pipe 6 through a circulation pipe 4, and a regulating valve 7 is provided on the bypass pipe 6; the inlet pipe 5 is connected to the water supply pipe 102, and the bypass pipe 6 is connected to the return water chamber 103; by providing the inlet pipe 5 and the bypass pipe 6, it is possible to control a part of the circulating water to dissipate heat through the packing in winter, and the other part of the circulating water does not dissipate heat through the packing, thereby adjusting the temperature of the circulating water; by providing the regulating valve 7, the ratio of water that dissipates heat and water that does not dissipate heat can be adjusted.

[0017] The water supply pipe 102 includes a main pipe 102a, which is connected to an inner pipe 102b and an outer pipe 102c; both the inner pipe 102b and the outer pipe 102c are provided with nozzles 102d for spraying water onto the filler 101; the nozzle 102d on the outer pipe 102c is located on the outside of the inner pipe 102b; the main pipe 102a is provided with a gate valve for controlling the connection and disconnection between the main pipe 102a and the inner pipe 102b and the outer pipe 102c; by providing the inner pipe 102b, the outer pipe 102c and the gate valve, the circulating water can be controlled to enter the inner pipe 102b or the outer pipe 102c, or enter the outer pipe 102c and the inner pipe 102b at the same time.

[0018] The condenser 2 is connected to the steam turbine 9 through a pipeline; the steam generated by the steam turbine 9 is condensed into water by the condenser 2 and then supplied to the boiler.

[0019] The working principle of the above embodiment is:

[0020] Under normal conditions, the regulating valve 7 is closed, and all the circulating water enters the water supply pipe 102 through the water inlet pipe 5, and then is sprayed onto the filler 101 for heat dissipation; in winter, part of the circulating water enters the water supply pipe 102 through the water inlet pipe 5 to dissipate heat, and part of the circulating water enters the return water chamber 103 through the bypass pipe 6 without heat dissipation; when the amount of water entering the water supply pipe 102 is small, the circulating water can be controlled to flow only to the inner pipe 102b or only to the outer pipe 102c by closing the specified gate valve.

[0021] This embodiment can adjust the temperature of the cooling water supplied by the condenser cooling water supply system in winter, thereby preventing the circulating water from freezing and the equipment from being damaged by freezing.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
