Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of condensers, in particular to an axial steam inlet condenser. Background Art
[0002] A condenser is a heat exchanger that condenses the exhaust steam of a steam turbine into water, also known as a rehydrator. Condensers are mainly used in steam turbine power plants and are divided into two types: water-cooled condensers and air-cooled condensers. They are widely used. Existing condensers still have some shortcomings when in use: Existing condensers need to be processed through internally installed cooling pipes during use. In actual use, the cooling pipes are not only the most important components in the condenser, but also the most easily damaged components. Different factors may cause ulcer corrosion, impact corrosion, dezincification corrosion, hot spot corrosion, stress corrosion, corrosion fatigue, ammonia corrosion on the inside of the steam, and corrosion caused by the use of contaminated cooling water. When a part of the cooling pipe is damaged, it needs to be replaced. However, since the cooling pipe is an integrated structure, it can only be replaced as a whole, and the damaged parts cannot be taken out and replaced separately, resulting in a certain amount of waste and high maintenance costs.
[0003] At present, an existing axial steam inlet condenser (such as patent number: CN209181550U) discloses an axial steam inlet condenser, including a cylinder, wherein a plurality of cooling tubes are evenly arranged inside the cylinder, and each cooling tube is composed of at least two symmetrical parts.
[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:
[0005] 1. The existing device does realize a spliced cooling tube, but the spliced cooling tube used is only connected by a few connecting grooves and built-in springs. The springs will corrode during use and be easily damaged, resulting in loss of function. Moreover, the device only realizes the splicing method but does not have a corresponding sealing device. The coolant and condensed water will mix at the splicing point, resulting in a greatly weakened cooling effect. The coolant will also corrode the inner wall of the entire cooling bin, resulting in cooling water pollution.
[0006] 2. The heat dissipation function of the existing device completely relies on the stacked cooling tubes. Too many cooling tubes will make it very difficult to repair and disassemble. Too many cooling tubes will also cause a great burden on the coolant pump, consuming more power resources and causing waste of resources. A cooling tube with higher heat dissipation capacity should be designed.
[0007] 3. The steam treatment chamber of the device is not provided with a guide device at the contact position with the cooling pipe, which causes most of the steam to accumulate on the surface in contact with the steam chamber, thus greatly affecting the cooling function. Utility Model Content

A secondary thread 1901 is provided inside, and the secondary thread 1901 is spirally engaged with the main thread 19. A water-blocking sleeve 22 is provided at one end of the condensate pipe interface 23 close to the condensate pipe joint 18. The outer wall of the main condensate pipe 17 is provided with two heat dissipation devices, including heat dissipation fins 16 and annular heat dissipation fins 15. A detection pipe 14 is provided at the center of the mounting frame 13. The outer wall of the detection pipe 14 is connected to the annular heat dissipation fins 15 and the heat dissipation fins 16, which greatly increases the steam surface in contact with the steam, and replaces the original structure of the stacked condensate pipes with a good heat absorption structure.
[0037] A plurality of auxiliary condensing pipes 11 are arranged inside the steam diversion chamber 12 , one end of the auxiliary condensing pipe 11 is fixedly connected to the water inlet pipe 4 , and the other end is connected to the water outlet pipe 5 . Cold water of the auxiliary condensing pipe 11 is input through the water inlet pipe 4 and then output through the water outlet pipe 5 .
[0038] A plurality of main condensing pipes 17 are arranged inside the cooling bin 1 . The main condensing pipes 17 are distinguished by annular heat sinks 15 and heat sink fins 16 , are arranged in a staggered manner, and are separated by mounting frames 13 , thereby achieving more stable fixation.
[0039] The diameter of the heat dissipating fin 16 is the same as the diameter of the second sealing ring 21. The annular heat sink 15 is distributed in a ring along the outer wall of the main condenser pipe 17, and the diameter of the annular heat sink 15 is calculated along the center of the main condenser pipe 17.

[0041] The water-blocking sleeve 22 is sleeved with the second sealing ring 21, and the first sealing ring 20 is connected to the interface end of the condensate pipe interface 23 to achieve sealing.
[0042] The detection pipe 14 is internally installed with a water quality detection sensor and a water pressure sensor for detecting the state in the cooling chamber.
[0043] Working principle: In the first step, steam is sent into the steam chamber 7 through the steam pipe 6, and the steam chamber 7 guides the steam into the entire steam diversion bin 12 through the diversion hole 1202. The auxiliary condenser pipe 11 inside the steam diversion bin 12 preliminarily cools and differentiates the steam so that the steam is evenly cooled. The steam is then completely liquefied through the main condenser pipe 17 and introduced into the condensate outlet 9 through the diversion groove 8 to discharge the condensed water.
[0044] In the second step, the cold water of the auxiliary condenser pipe 11 is input through the water inlet pipe 4 and then output through the water outlet pipe 5, and the coolant of the main condenser pipe 17 is input through the coolant inlet 2 and then output through the coolant outlet 3.
[0045] In the third step, the condensate pipe joint 18 and the condensate pipe interface 23 are connected by the engagement of the main thread 19 and the secondary thread 1901, and the first sealing ring 20 is squeezed and connected with the end of the condensate pipe interface 23 to achieve the first layer of sealing, and then the second sealing ring 21 is connected with the waterproof sleeve 22 to achieve the second layer of sealing and realize waterproofing.
[0046] In the fourth step, when the detection pipeline 14 detects that there is a problem with the water quality or water pressure, the pressure relief pipe port 10 is opened to discharge the condensed water.
[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
