Description
Technical Field
[0001] This utility model belongs to the field of condenser technology, specifically relating to a boiler condenser. Background Technology
[0002] A condenser is a heat exchange device that uses a cooling medium (such as water or air) to condense steam into a liquid. A condenser generally consists of an outer shell, heat exchange tube bundles, a steam inlet, a condensate outlet, and cooling medium inlet and outlet. The principle is that steam enters the outer shell of the condenser from the top or side, filling the space between the heat exchange tube bundles. The cooling medium, such as water, flows in from one end of the heat exchange tube bundles and absorbs the heat of the steam through the tube walls, causing the steam to change from a gaseous state to a liquid state, i.e., condensate. The condensate collects at the bottom of the condenser and is transported out through other equipment, such as a condensate pump. The condensate can be returned to the boiler to be heated into steam, which can reduce water resources and realize steam energy recovery.
[0003] In traditional tubular condensers, steam enters the shell from the top. Due to the dense, concentric ring-shaped distribution of the internal tube bundles, a staged condensation effect is achieved. Steam enters from the top of the condenser shell to the bottom, first contacting the externally distributed ring-shaped tube bundles, and then the internal tube bundles. However, the dense distribution of the tube bundles obstructs the flow of steam, preventing uniform diffusion within the condenser shell. This results in some tube bundles not fully contacting the steam. The condenser lacks a design that guides steam flow to ensure uniform steam distribution and contact with the tube bundles, which is flawed and requires improvement.
[0004] Existing tubular condensers have the problem of lacking a flow guide design to ensure uniform steam distribution and contact with the tube bundle. To address this, this application proposes a boiler condenser. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 5This utility model provides a technical solution: a boiler condenser, including a condenser mechanism, comprising a condenser shell 12, an inlet tank 11 and an outlet tank 13 distributed on both sides of the condenser shell 12, a water collection tank 14 communicating with the bottom surface of the condenser shell 12, a tube bundle 15 penetrating the condenser shell 12, and a steam inlet pipe 16 welded to and internally communicating with the top shell of the condenser shell 12. During condensation, steam enters the interior of the condenser shell 12 through the steam inlet pipe 16, and cooling medium water enters from the inlet tank 11. After the water medium enters the tube bundle 15, it flows out from the outlet tank 13. The steam comes into contact with the tube wall of the tube bundle 15, and the water medium carries away the heat. The steam condenses into condensate and accumulates in the collection tank 14 before being discharged. The support components include fixing strips 51 installed inside the condenser shell 12 and fixing plates 52 installed between opposing fixing strips 51. The fixing strips 51 are welded to the condenser shell 12, and the fixing strips 51 are welded to the fixing plates 52. The fixing plates 52 fix and support the tube bundle 15 and are wavy. The shape of the tube bundles 15 is such that adjacent tube bundles 15 are staggered to avoid obstructing steam flow and to ensure full contact between steam and the staggered tube bundles 15. The fixed support plates 52 inside the condenser shell 12 can be designed in parallel, and the specific number of fixed support plates 52 and tube bundles 15 can be designed according to actual conditions. The steam diffusion mechanism includes a concentrator shroud 2 and a fixed ring 3 fixed by bolts, a diversion plate 4 welded to the fixed ring 3, and a diffuser cylinder 6 welded to the bottom surface of the diversion plate 4. The surface of the diversion plate 4 is opened. A diversion hole 41 is provided. The steam inlet 16 is fixed to the concentrator 2 by bolts. When the steam enters the steam inlet 16, the steam flows in a direction under the guidance of the concentrator 2 and the fixed ring 3. The steam is diverted by the diversion plate 4, so that the steam passes through the diversion hole 41. The diverted part of the steam enters the interior of the condenser shell 12. The diverted part of the steam diffuses on the surface of the diffuser 6. The diffuser 6 diffuses the steam to the space position of the inner side wall of the condenser shell 12, so that the steam is evenly distributed inside the condenser shell 12.
[0027] In this embodiment, the concentrator 2 is a funnel shape with one end wide and the other end narrow. The top of the fixed ring 3 is connected to the narrow end of the concentrator 2. The concentrator 2, the fixed ring 3 and the center of the steam inlet 16 are on the same axis. The steam flows in a direction under the guidance of the concentrator 2 and the fixed ring 3. The steam is divided by the diverter plate 4.
[0028] In this embodiment, the diffuser 6 is a hollow cone structure. The narrow end of the top of the diffuser 6 is connected to the bottom surface of the diversion plate 4. The diverted part of the steam diffuses on the surface of the diffuser 6. The diffuser 6 diffuses the steam to the space position of the inner side wall of the condenser shell 12, so that the steam is evenly distributed inside the condenser shell 12.
[0029] In this embodiment, radially distributed guide plates 7 are fixed on the outer surface of the diffuser 6. The guide plates 7 are streamlined and serve to guide the flow, thereby diverting the steam on the surface of the diffuser 6.
[0030] In this embodiment, a circular diffusion lip 8 is fixed at the wide end of the bottom of the diffusion cylinder 6. The cross-section of the diffusion lip 8 is arc-shaped and curved, which extends the range of diffusion outward from the surface of the diffusion cylinder 6.
[0031] In this embodiment, the fixed support plate 52 is wavy in shape, and the surface of the fixed support plate 52 is provided with pipe holes 53 for the tube bundle 15 to pass through. The tube bundle 15 passes through the pipe holes 53 on the fixed support plate 52, so that the adjacent tube bundles 15 are staggered, so as to avoid the adjacent tube bundles 15 from obstructing the flow of steam and to allow the steam to fully contact the staggered tube bundles 15.
[0032] In this embodiment, the fixing strip 51 is long and the surface of the fixing strip 51 facing away from the fixing support plate 52 is curved. When steam comes into contact with the fixing strip 51, the steam is diverted on the curved surface of the fixing strip 51.
[0033] Working principle and usage process of this utility model:
[0034] During condensation, steam enters the interior of the condenser shell 12 through the steam inlet 16, and the cooling medium water enters through the inlet tank 11. After entering the tube bundle 15, the water flows out through the outlet tank 13. The steam comes into contact with the tube wall of the tube bundle 15, and the medium water carries away the heat. The steam condenses into condensate and accumulates in the collection tank 14 before being discharged.
[0035] When steam enters the steam inlet 16, it flows in a direction under the guidance of the concentrator 2 and the fixed ring 3. The steam is then divided by the diversion plate 4, allowing it to pass through the diversion hole 41.
[0036] Part of the diverted steam enters the interior of the condenser shell 12, and then the steam comes into contact with the tube bundle 15.
[0037] The diverted steam diffuses on the surface of the diffuser 6, which diffuses the steam toward the space of the inner wall of the condenser shell 12, so that the steam is evenly distributed inside the condenser shell 12.
[0038] The streamlined guide plate 7 serves to guide the flow, allowing the steam on the surface of the diffuser 6 to be diverted. The diffuser lip 8 is curved, extending the range of diffusion outward from the surface of the diffuser 6.
[0039] Adjacent tube bundles 15 are staggered to avoid obstructing the flow of steam and to ensure that the steam can fully contact the staggered tube bundles 15.
[0040] In summary, the condenser of this application is equipped with a steam guide design that guides the steam and makes it evenly distributed. The steam guides the steam to contact the tube bundle 15. Under the guidance of the flow distribution plate 4, the diffuser 6 and the guide plate 7, the diffuser 6 diffuses the steam to the spatial position of the inner wall of the condenser shell 12, so that the steam is evenly distributed inside the condenser shell 12. The steam contacts the staggered tube bundle 15, so that the steam is evenly distributed.
