Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steam-water separation of steam generators, in particular to a tube bundle of a steam-water separator. Background Art
[0002] Steam-water separation is a very important step in a steam generator, because the steam generated in a steam generator often contains a large amount of water. If this water cannot be effectively separated and removed, it will affect the quality of the steam and the normal operation of the equipment.
[0003] The steam-water separation device is an indispensable part of the overall design of the steam generator. Its main function is to quickly separate the water content in saturated steam, improve the steam dryness and ensure the normal operation of the steam generator to meet user needs.
[0004] The current steam-water separator is still installed on the upper header structure, the steam saturation is not very high and the steam-water separation efficiency is not high. Utility Model Content
[0005] Aiming at the shortcomings of the prior art that the steam saturation is not very high and the steam-water separation efficiency is not high, the utility model provides a tube bundle of a steam-water separator.
[0006] The utility model provides the following technical solution: a tube bundle of a steam-water separator, wherein the steam-water separator is arranged in the upper part of the tube bundle, the steam-water separator comprises a nearly cylindrical enclosed space, the nearly cylindrical enclosed space is communicated with the steam of the tube bundle, a tube with a plurality of steam holes around is fixedly arranged at one end of the nearly cylindrical enclosed space, and the tube is kept at a distance from the other end of the nearly cylindrical enclosed space.
[0007] As an improvement of the above solution, the bottom surface 3 of the tube is hollow, so that the soda and water can shuttle upward from the bottom, and the separation efficiency is improved.
[0008] Compared with the prior art, the utility model provides a tube bundle of a steam-water separator, which has the following beneficial effects:
[0009] The steam-water separation device is fully integrated into the tube bundle, and its advantages are that the steam and water collide and shuttle through a number of steam holes, the steam-water separation efficiency is high, the water content of the steam is further reduced, the quality is high, the nearly cylindrical enclosed space is small, the steam storage capacity is small, and the safety performance is reliable.
[0010] The water vapor process is: softened water is heated → boiled → evaporated → water vapor (gas-liquid phase change occurs in the tube) → saturated water vapor (upper tube trough) → saturated steam (upper tube trough) → supersaturated steam (gas-liquid separator enhances steam quality) → steam supply (high-quality steam); in short, the utility model is a key component for enhancing supersaturated steam to high-quality steam.
[0011] Main features: extremely fast steam generation, high quality steam transformation, and high design safety performance. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the utility model;
[0013] In the figure: 1. Lower tube bundle; 2. Steam-water separator; 3. Bottom surface; 4. Steam hole; 5. Upper tube bundle. Implementation
[0014] See also Figure 1 ,
[0015] A tube bundle of a steam-water separator, a tube bundle of a steam-water separator, a steam-water separator 2 is arranged in the upper part of the tube bundle, the steam-water separator 2 includes a nearly cylindrical enclosed space, the nearly cylindrical enclosed space is communicated with the steam of the tube bundle, a tube with a plurality of steam holes 4 around is fixedly arranged at one end of the nearly cylindrical enclosed space, and the tube keeps a distance from the other end of the nearly cylindrical enclosed space.
[0016] The bottom surface 3 of the tube is hollow, so that the soda and water can pass upward from the bottom surface, thereby improving the separation efficiency.
[0017] The tube bundle is divided into a lower tube bundle 1 and an upper tube bundle 5. A steam-water separator 2 is sealed and welded between the lower tube bundle 1 and the upper tube bundle 5, so that the firmness is enhanced and the service life is prolonged.
[0018] The steam holes 4 are arranged in 4 rows at equal intervals along the circumference, so that the steam-water separation efficiency is further improved.
[0019] The water level is in a stable state in the tube bundle of the steam-water separator of the utility model. After being heated at high temperature in the furnace, the water in the tube bundle of the steam-water separator of the utility model begins to heat up, boil, and change phase to water vapor due to the radiation heat, and then enters the upper tube groove, undergoes high-temperature heating and drying treatment, and changes into saturated steam and enters the steam-water separator 2. The saturated steam passes through the steam-water separator 2 and is purified and changes into high-quality steam with extremely low water content for external use.
