Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically a seawater heat exchanger. Background Technology
[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and have a wide range of applications. Seawater contains a lot of impurities, some of which are corrosive media themselves, and some are transformed into corrosive media during processing. Therefore, a seawater heat exchanger is needed.
[0003] Although existing seawater heat exchangers offer many advantages, they still suffer from the following problems: Seawater contains a large number of trace elements and floating matter. After a period of heat exchange, the heat exchange tubes inside the heat exchanger need to be cleaned to ensure heat exchange quality. Traditional cleaning methods are time-consuming, labor-intensive, and inefficient. Furthermore, in practical use, traditional heat exchangers have poor overall rigidity, which can negatively impact the overall lifespan of the equipment. Utility Model Content
[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0005] 1. Technical problems to be solved:
[0006] To address the problems mentioned above, such as the time-consuming and labor-intensive nature of traditional cleaning methods, low cleaning efficiency, and the poor overall rigidity of traditional heat exchangers which can affect the service life of the entire equipment, this utility model is proposed.
[0007] Therefore, the purpose of this utility model is to provide a seawater heat exchanger that aims to solve the problems of traditional cleaning methods, such as requiring a lot of time, high labor intensity, and low cleaning efficiency, and to maintain the surface of the heat exchanger body as hard as possible.

[0009] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0010] A seawater heat exchanger includes a heat exchanger body, a filter box bolted to the side wall of the heat exchanger body, an inner cavity inside the filter box, a plurality of equally spaced partition plates welded to the inner wall of the inner cavity, a pipe connected to the top of the filter box via a flange, a circulation pump fitted around the outer circumference of the pipe, a water tank fitted around the outer circumference of the pipe, a booster pump fitted around the outer circumference of the pipe, a water collection seat connected to one side of the pipe via a flange, and the outer circumference of the water collection seat connected to one side of the heat exchanger body via a flange.
[0011] In a preferred embodiment of the seawater heat exchanger of this utility model, the water collection base has a water guiding groove inside, the inner wall of the water guiding groove has a groove, the inner wall of the groove is fitted with a rubber ring, and multiple annularly distributed diversion pipes are fitted inside the rubber ring. The structural design of the water guiding groove facilitates the buffering effect on the water source, reduces the impact on the diversion pipes, and facilitates the maintenance of the device's service life. The rubber ring on the inner wall of the groove further enhances the sealing effect of the diversion pipes during the diversion process.

[0015] 3. Beneficial effects:
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This type of seawater heat exchanger uses a circulating pump to draw water from the tank and a booster pump to pressurize it. The pressurized water then enters the interior of the heat exchanger body through a distribution pipe to clean it, thus improving cleaning efficiency. At the same time, a filter box is bolted to the side wall of the heat exchanger body. The cleaned water enters the filter box and is filtered through a filter screen and a grid. The circulating pump is then started, and the filtered water in the filter box is pumped back into the tank through a pipeline, realizing the secondary use of water and improving water utilization efficiency.
[0018] This type of seawater heat exchanger features an epoxy resin coating on the inner surface of the heat exchanger body that is in direct contact with seawater, which enhances the corrosion resistance of the metal on the seawater side. In addition, the heat exchanger body also includes a Monel alloy layer, which further enhances the overall structure's resistance to seawater corrosion. Furthermore, the outer surface of the heat exchanger body is covered with a carbon steel layer, which, in addition to its corrosion resistance, also possesses high rigidity, facilitating the maintenance of the overall strength and stability of the device.

[0032] Please see Figures 1-5 This utility model provides a technical solution:
[0033] A seawater heat exchanger includes a heat exchanger body 1. A filter box 2 is bolted to the side wall of the heat exchanger body 1. The filter box 2 has an inner cavity 3. Multiple equally spaced partition plates 18 are welded to the inner wall of the inner cavity 3. A pipe 6 is connected to the top of the filter box 2 via a flange. A circulation pump 8 is fitted around the outer circumference of the pipe 6. A water tank 7 is fitted around the outer circumference of the pipe 6. A booster pump 9 is fitted around the outer circumference of the pipe 6. The circulation pump 8 draws water from the water tank 7 and the booster pump 9 pressurizes the water.
