Description

Technical Field

[0001] The present application relates to the technical field of condenser equipment, and in particular to a corrosion-resistant and high-efficiency seawater condenser. Background Art

[0002] Shell and tube condensers are a common type of heat exchanger, primarily used to extract heat from gas or vapor and transfer it to a cooling medium. Shell and tube condensers operate based on the principles of heat transfer through conduction and convection. The hot gas or vapor transfers heat through the metal walls of the condenser tubes to the outer surface, where it is absorbed by the cooling medium.

[0003] Seawater contains large amounts of salt, sediment, microorganisms, and organic matter. These substances easily deposit on the heat exchanger surface, forming fouling. The presence of fouling increases thermal resistance, hindering heat transfer and reducing the heat exchanger's efficiency. It also affects seawater circulation, reducing the cooling efficiency of the seawater condenser. Furthermore, the salt and other corrosive substances in the fouling chemically react with the metal surfaces of the heat exchanger, increasing the potential for corrosion. Utility Model Content

[0004] In order to reduce the rate of internal fouling in the heat exchanger and ensure the heat exchange efficiency of the seawater condenser, the present application provides a corrosion-resistant and high-efficiency seawater condenser.

[0005] The present application provides a corrosion-resistant and efficient seawater condenser adopting the following technical solutions:

[0006] A corrosion-resistant and high-efficiency seawater condenser comprises a base, a shell is provided on the base, a heat exchange tube is provided in the shell, the heat exchange tube is U-shaped, a liquid inlet and a liquid outlet are provided at both ends of the heat exchange tube, and the liquid inlet and the liquid outlet are arranged in the same direction, a filter plate is detachably provided on one side of the shell near the liquid inlet and the liquid outlet, a seawater inlet and a seawater outlet for passing seawater are provided on the shell, a guide pipe is provided at the seawater inlet, the guide pipe is trumpet-shaped, and the pipe mouth of the guide pipe gradually expands toward the interior of the shell.

[0007] By adopting this technical solution, the fluid flow within the heat exchange tubes is relatively smooth. Compared to some multi-pass straight tubes or heat exchange tubes with special structures, U-shaped tubes are less likely to form dead zones, reducing the possibility of dirt accumulation. Furthermore, the installation of trumpet-shaped flow guides slows the flow rate of seawater, allowing it to spread smoothly and achieve a uniform flow rate. This uniform flow distribution prevents dirt accumulation caused by localized slow seawater flow. Finally, the installation of filter plates prevents large pieces of dirt from entering the heat exchange tubes, ensuring heat exchange efficiency.

[0008] Optionally, a T-shaped slide groove is provided on the shell, and a guide groove arranged opposite to the T-shaped slide groove is provided on the edge of the filter plate. A slider for fixing the shell and the filter plate is slidably provided in the T-shaped slide groove.

[0009] By adopting the above technical solution, the slider is moved along the chute to the guide groove. At this time, the slider is located on the chute and the guide groove, which can prevent the filter plate from rotating. By setting the T-shaped chute, the slider can be prevented from falling off.

[0010] Optionally, a limiting plate is provided on the shell above the T-shaped slide groove, and elastic clamping plates for fixing the slider are fixed on both sides of the slider. The elastic clamping plates slide with the inner side of the limiting plate as the slider moves. When the elastic clamping plates are separated from the limiting plate, the elastic clamping plates can be clamped on the outer side of the limiting plate.

[0011] By adopting the above technical solution, the elastic clamping piece moves accordingly. When the slider is still in the T-shaped slide groove, the elastic clamping piece slides and cooperates with the inner side of the limiting plate. When the slider moves to the guide groove, the elastic clamping piece detaches from the limiting plate. At this time, the slider is pushed back in the opposite direction, so that the elastic clamping piece clamps the limiting plate and fixes it.

[0012] Optionally, the heat exchange tube is a spiral heat exchange tube.

[0013] By adopting the above technical solution, the spiral heat exchange tube can simultaneously enhance the convective heat transfer inside and outside the tube, and its comprehensive heat transfer coefficient is significantly improved compared to ordinary heat exchange tubes. In seawater condensers, this means that under the same heat exchange area, the spiral heat exchange tube can achieve higher heat exchange efficiency;

[0014] The turbulence generated by the spiral heat exchange grooves creates a more even distribution of fluid velocities inside and outside the tubes, with relatively high flow rates. For the seawater outside the tubes, the higher velocity and turbulence create a strong scouring effect on the tube walls. This scouring prevents dirt particles in the seawater from stably adhering to the tube walls.

[0015] Optionally, a partition plate is horizontally arranged at the center of the shell to separate the heat exchange tubes, and a guide plate is arranged on the shell. The guide plates are evenly arranged along the horizontal direction of the heat exchange tubes, and the guide plates are all arranged perpendicular to the heat exchange tubes.

[0016] By employing this technical solution, the guide plate can redirect the fluid flow, directing it along a predetermined path. The flow of seawater can exert a strong scouring effect on the surface of the heat exchange tubes. Seawater typically contains dirt such as silt, algae, and microbial mucous membranes. Effective scouring can remove these dirt particles from the surface of the heat exchange tubes.

[0017] Optionally, a connecting plate is provided at the bottom of the guide plate, and the connecting plate is connected to the outer shell by bolts.

[0018] By adopting the above technical solution, the guide plate, the partition plate and the shell can be detachably connected, which facilitates the installation and removal of the heat exchange tubes and improves the efficiency of cleaning the heat exchange tubes.

[0019] Optionally, the seawater outlet is provided with a check valve, which includes a valve body, a valve stem, a torsion spring and a valve plate. The torsion spring is sleeved on the valve stem, and the valve plate is fixed to the valve stem.

[0020] By adopting this technical solution, the pressure of seawater overcomes the elastic resistance of the torsion spring, pushing the valve disc open and allowing fluid to flow smoothly through the check valve. If the fluid flow direction changes or stops, the spring force of the valve core quickly closes, preventing the fluid from flowing in the opposite direction. This prevents liquid from flowing back and accumulating inside the housing, causing corrosion and dirt accumulation.

[0021] Optionally, the surface of the shell and the heat exchange tube is provided with an anti-corrosion coating.

[0022] By adopting the above technical solution, the anti-corrosion coating can form an effective protective film on the metal surface, preventing the contact between seawater and metal, and improving the corrosion resistance of the seawater condenser.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up the housing, filter plate, T-shaped slide, slider, limit plate and elastic clamping piece, the installation of the filter plate is simpler and more convenient, and the quick disassembly function is realized, which can fix the filter plate. The elastic clamping piece enhances the firmness of the filter plate installation;

[0025] 2. By installing a guide plate, a check valve, and a spiral heat exchange tube, the convection heat exchange inside and outside the tube can be enhanced simultaneously, achieving higher heat exchange efficiency. At the same time, once the flow direction of the fluid changes or stops, the valve core spring force quickly closes to prevent the fluid from flowing in the opposite direction. This prevents the backflow of liquid from accumulating inside the shell and causing corrosion and dirt accumulation.

[0026] 3. The use of spiral heat exchange tubes improves the flow velocity and turbulence of the fluid in the heat exchange tubes, enhances the heat exchange effect, and is not easily damaged by water flow impact; by detachably installing the filter plate on one side of the shell, daily cleaning and maintenance work is facilitated, ensuring the long-term stable operation of the condenser; by providing a trumpet-shaped guide pipe at the liquid inlet, the cooling water source can enter the heat exchange tubes more evenly, avoiding the occurrence of local overheating, and further improving the working efficiency of the entire device.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a corrosion-resistant and efficient seawater condenser. Figure 1 A corrosion-resistant, high-efficiency seawater condenser includes a base 1, upon which a housing 2 is mounted. A trumpet-shaped flow conduit 14 for passing seawater is provided on the sidewall of the housing 2. The flow conduit 14 is flared, with the opening gradually expanding toward the interior of the housing 2. A seawater inlet 3 is provided in the flow conduit 14, and a seawater outlet 4 is provided on the other side of the housing 2 opposite the flow conduit 14. One end of the housing 2 is open, and a filter plate 5 is disposed at the opening.

[0035] Reference Figure 1 and Figure 2 A T-shaped chute 6 is provided on the side wall of the housing 2 at the opening thereof and in contact with the filter plate 5. A guide groove 7 is provided on the edge of the filter plate 5, which is arranged opposite to the T-shaped chute 6. A slider 8 is slidably provided in the T-shaped chute 6 to fix the housing 2 and the filter plate 5. By placing the slider 8 between the guide groove 7 and the T-shaped chute 6, the filter plate 5 is fixed and prevented from rotating.

[0036] Reference Figure 1 and Figure 2To further secure the filter plate 5, a restricting plate 9 is fixedly mounted on the housing 2 above the T-shaped chute 6. Two restricting plates 9 are provided, positioned opposite each other on either side of the T-shaped chute 6. Elastic clamping pieces 10 are fixedly mounted on either side of the slider 8 to secure the position of the slider 8. As the slider 8 moves, the elastic clamping pieces 10 move with it. While the slider 8 remains within the T-shaped chute 6, the elastic clamping pieces 10 slide in engagement with the inner side of the restricting plate 9. When the slider 8 moves to the receiving groove 7, the elastic clamping pieces 10 disengage from the restricting plate 9. At this point, the slider 8 is pushed back in the opposite direction, causing the elastic clamping pieces 10 to clamp the restricting plate 9, securing it.

[0037] Reference Figure 1 、 Figure 2 and Figure 3 The shell 2 is provided with a heat exchange tube 11. In order to improve the heat exchange efficiency, the heat exchange tube 11 is provided with a spiral heat exchange tube 11. The heat exchange tube 11 is U-shaped. The two ends of the heat exchange tube 11 are provided with a liquid inlet 12 and a liquid outlet 13. The liquid inlet 12 and the liquid outlet 13 are arranged in the same direction for carrying the liquid to be cooled. In order to enhance the corrosion resistance of the condenser as a whole, the shell 2 and the heat exchange tube 11 are provided with an anti-corrosion coating.

[0038] Reference Figure 3 and Figure 4 Inside the shell 2, partitions 15 are installed horizontally along the heat exchange tubes 11. Shell 2 is also equipped with guide plates 16, evenly spaced horizontally along the heat exchange tubes 11. These guide plates 16 are positioned perpendicular to the tubes 11. Seawater flows through these guide plates, redirecting its flow and ensuring sufficient contact and heat exchange. A connecting plate 17 is fixed to one end of the guide plate 16, near the shell 2. To secure the guide plate 16, the connecting plate 17 is bolted to the shell.

[0039] Reference Figure 1 and Figure 5 The seawater outlet 4 is provided with a check valve comprising a valve body 18, a valve stem 19, a torsion spring 20, and a valve plate 21. The torsion spring 20 is sleeved on the valve stem 19, and the valve plate 21 is fixed to the valve stem 19. When seawater passes through, the torsion spring 20 drives the valve plate 21 to rotate, allowing the seawater to flow out. The action of the torsion spring 20 also makes it difficult for the external seawater to push the valve stem 19 to rotate, thereby preventing the fluid from flowing in the opposite direction.

[0040] The principle of the corrosion-resistant, high-efficiency seawater condenser according to the present invention is as follows: seawater flows in through the seawater inlet 3 and out through the seawater outlet 4. The liquid to be cooled enters the heat exchange tube 11 through the liquid inlet 12 and out through the liquid outlet 13. The seawater flows along the pipe between the shell 2 and the heat exchange tube 11. Under the action of the flow guide 14, the seawater flows around the surface of the heat exchange tube 11, fully contacting the heat exchange tube 11 and accelerating the heat exchange efficiency.

[0041] The filter plate 5 and trumpet-shaped flow guide 14 prevent large pieces of dirt from flowing into the heat exchange tube 11, slowing the flow rate of seawater and allowing it to spread smoothly, making the seawater flow uniform. This uniform flow distribution prevents dirt from settling due to slow local seawater flow, thus ensuring heat exchange efficiency. The connection method of the filter plate 5 makes it easier to install and replace the filter plate 5, ensuring a tight connection between the filter plate 5 and the housing 2 while improving the convenience of equipment maintenance. Finally, a check valve is provided to prevent reverse flow of the fluid, further preventing liquid from reflux and accumulating inside the housing 2, causing corrosion and dirt accumulation.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
