Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a condenser for a steam turbine used for steam power generation. Background Art

[0002] The condenser for a steam turbine for steam power generation is a device for condensing the exhaust steam of the steam turbine into condensate. It mainly uses a cooling medium to absorb the heat of the steam when high-temperature and high-pressure steam enters the condenser, so that the heat energy in the steam is transferred to the cooling medium and then condensed into liquid. It is an indispensable part of the use of a steam turbine for steam power generation and is used in various steam power generation occasions. When the existing condenser for a steam turbine for steam power generation is used, the cooling medium is generally transferred through a heat pipe. However, the heat pipe is a fixedly installed structure. Therefore, when the heat pipe contacts the steam, the steam moves from top to bottom. After the steam absorbs the heat through the top heat pipe, the bottom heat pipe cannot completely absorb the heat and cannot fully absorb the heat, making it impossible for the condenser to efficiently and fully condense the steam into condensate. In addition, when the heat pipe with a fixed installation structure inputs condensate, the condensate cannot evenly enter the heat-conducting copper pipe, resulting in an inability to use it stably.

Rotating clamps 11 are fixedly installed on both sides of the inner walls of the bottom cylinder body 1 and the top cylinder cover 2. Two copper tube mounting plates 12 are arranged inside the bottom cylinder body 1 and the top cylinder cover 2. A plurality of heat-conducting copper tubes 14 are fixedly installed in the middle of the two copper tube mounting plates 12. A plurality of water guide holes 15 are opened inside the copper tube mounting plates 12. A rotating connecting frame 16 is movably installed on the other side of the first side cover plate 7.

[0020] In this embodiment, the bottom cylinder body 1 is located at the lower end of the top cylinder cover 2 and is fixedly connected thereto. The bottom cylinder body 1 and the top cylinder cover 2 are arranged in a cylindrical shape, and the bottom cylinder body 1 and the top cylinder cover 2 constitute the main body.

[0021] In this embodiment, the condensation water inlet pipe 3, the condensation water outlet pipe 4 and the condensation water tank 5 are all connected to the interior of the bottom cylinder body 1, the condensation water inlet pipe 3 and the steam input pipe 6 are located on one side of the copper tube mounting plate 12, and the condensation water tank 5 is located below the heat-conducting copper tube 14. The condensation water inlet pipe 3, the condensation water outlet pipe 4 and the condensation water tank 5 respectively serve to input condensation water, output condensation water and output condensation water.

[0022] In this embodiment, the steam input pipe 6 is connected with the interior of the top cylinder cover 2, and the steam input pipe 6 is located above the heat-conducting copper tube 14. Both ends of the heat-conducting copper tube 14 are connected with the water guide hole 15, and the steam input pipe 6 plays the role of inputting steam.

[0023] In this embodiment, the rotating clamp 11 is inserted into the rotating slot 13 for fitting connection, and the copper tube mounting plate 12 rotates around the rotating clamp 11 through the rotating slot 13 , and the rotating clamp 11 is movably mounted on the copper tube mounting plate 12 through the rotating slot 13 .

[0024] In this embodiment, the rotating shaft of the driving motor 10 passes through the first side cover plate 7 and is fixedly connected to the rotating connecting frame 16. The rotating connecting frame 16 is fixedly connected to the copper tube mounting plate 12 on one side. The driving motor 10 drives the copper tube mounting plate 12 to rotate through the rotating connecting frame 16.

[0025] It should be noted that the utility model is a condenser for a steam turbine used for steam power generation. When in use, the bottom cylinder body 1, the top cylinder head 2, the first side cover plate 7 and the second side cover plate 8 constitute the main part of the condenser. The steam generated by the steam turbine enters the bottom cylinder body 1 and the top cylinder head 2 through the steam input pipe 6, and then the steam contacts the heat-conducting copper tube 14, and condensed water is input through the condensation water inlet pipe 3. After the water enters the bottom cylinder body 1 and the top cylinder head 2, it enters the heat-conducting copper tube 14 along the water guide hole 15 on the copper tube mounting plate 12 to form a cooling medium, so that the cooling medium of the heat-conducting copper tube 14 absorbs the heat of the steam, so that the heat energy in the steam is transferred to the cooling medium, and then condensed into condensed water, which drops into the condensed water tank 5 for discharge, and the condensed water after absorbing heat is discharged from the water guide hole 15 on the copper tube mounting plate 12 on the other side, and then discharged through the condensed water outlet pipe 4, thereby realizing the condensation process;

[0026] When the heat-conducting copper tube 14 contacts the steam, the operation of the driving motor 10 drives the rotating connecting frame 16 to rotate, and the rotating connecting frame 16 drives the copper tube mounting plate 12 to rotate. At the same time, the copper tube mounting plate 12 rotates around the rotating clamping ring 11 through the rotating clamping groove 13. The rotating clamping ring 11 also plays a role in sealing the two sides of the two copper tube mounting plates 12. Therefore, the heat-conducting copper tube 14 between the two copper tube mounting plates 12 also rotates, so that multiple heat-conducting copper tubes 14 rotate to contact the steam, so that multiple heat-conducting copper tubes 14 are evenly in contact with the steam to absorb heat. When condensed water is input into the condensation water inlet pipe 3, the structure of the rotating copper tube mounting plate 12 and the water guide hole 15 also enables the condensed water to evenly enter the water guide hole 15 and the heat-conducting copper tube 14 when entering the water guide hole 15 from the bottom cylinder body 1 and the top cylinder cover 2.
