[0001] The utility model relates to the technical field of coolers, and particularly relates to a seawater cooler resistant to hydrogen sulfide. Background Art
[0002] A seawater cooler is an efficient heat exchange device specifically designed to use seawater as a cooling medium for industrial cooling processes. Since seawater contains hydrogen sulfide, alloy steel materials are used for the heat exchange tubes of the seawater cooler in the design, which can maintain the hydrogen sulfide resistance of the heat exchange tubes and reduce the erosion effect of seawater on the heat exchange tubes.
[0003] During the use of the existing coolers, although there are many benefits, there are still the following problems. The cleaning steps for the heat exchange tubes in the cooler are relatively complex. After the existing heat exchange tubes are used for a long time, impurities in the heat exchange medium will adhere to the inner wall of the heat exchange tubes. Therefore, it is necessary to disassemble the cooler and transport a dissolving solution to the inner wall of the heat exchange tubes to dissolve and clean the impurities. The cleaning efficiency is low, and the cooler needs to be shut down, resulting in poor smoothness of use of the cooler. Summary of the Utility Model

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.
[0029] In order to save manpower and improve efficiency, as an embodiment of the present utility model, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, a hydrogen sulfide-resistant seawater cooler of the present utility model includes a housing 1, a connection cover 2, a push rod body 3, and a connection disk 13. Connection covers 2 are provided on the outer walls on both sides of the housing 1. A second water pipe 21 is inserted and installed on one side of the upper outer wall of the connection cover 2. A rotating shaft 22 is rotatably installed on one side of the inner wall of the connection cover 2. A push rod body 3 is provided on one side of the inner wall of the connection cover 2. A sealing cover 31 is installed on the outer wall of one end of the push rod body 3.
[0030] During use, the cooling medium is pressurized by an external liquid pump and then transported into the second water pipe 21, and enters the connection cover 2 through the second water pipe 21, so that the cooling medium circulates inside the heat exchange tube body 14 to cool the heat exchange tube body 14. The heat exchange medium flows into the housing 1 through the first water pipe 12 and contacts the heat exchange tube body 14, and the cooling medium exchanges heat with the heat exchange medium through the heat exchange tube body 14.
[0031] For connecting the connection cover 2, exemplarily, as Figure 1 shown, flange plates 11 are welded on the outer walls of the housing 1 and the connection cover 2. The housing 1 and the connection cover 2 are connected through the flange plates 11. Bolts are arranged in a circular array inside the flange plates 11.
[0032] During use, the flange plates 11 are connected by bolts, so that the housing 1 and the connection cover 2 maintain the connection stability and sealing performance with each other through the flange plates 11, ensuring the sealing performance of the direct flow between the housing 1 and the connection cover 2.
[0033] For the heat exchange medium to flow, exemplarily, as Figure 1 shown, first water pipes 12 are inserted and installed on the outer walls on the upper and lower sides of the housing 1. The first water pipes 12 are communicated with the inside of the housing 1.
[0034] During use, the heat exchange medium enters the housing 1 through the first water pipe 12 and contacts and exchanges heat with the heat exchange tube body 14 inside the housing 1, achieving the purpose of cooling the heat exchange medium.
[0035] For heat exchange, exemplarily, as Figure 2 shown, connection disks 13 are rotatably installed on both sides of the inner wall of the housing 1. The connection disks 13 are connected to the rotating shafts 22. Heat exchange tube bodies 14 are inserted and installed in a circular array inside the connection disks 13.
[0036] During use, the connection disks 13 can rotate in the housing 1 and maintain the relative position stability through the rotating shafts 22. The cooling medium rotates and flows inside the heat exchange tube bodies 14, so as to exchange heat and cool the heat exchange medium flowing outside the heat exchange tube bodies 14.
[0037] For adjusting the movement of the heat exchange tube body 14, exemplarily, as Figure 3As shown, the rotating shaft 22 passes through the outer wall of one end of the connecting cover 2 and a motor body 23 is provided. The motor body 23 is connected to the outer wall of the connecting cover 2.
[0038] When in use, the motor body 23 drives the rotating shaft 22 to rotate in a circle, so that the rotating shaft 22 can drive the connecting plate 13 to rotate in a circle, and the use position of the heat exchange tube body 14 is adjusted, thereby achieving cleaning of the heat exchange tube body 14 at different positions.
[0039] In order to block the heat exchange tube body 14, for example, Figure 3 As shown, a sealing gasket 32 is fixedly attached to the outer wall of the sealing cover 31, and the sealing gasket 32 and the outer wall of the sealing cover 31 are designed in an arc shape.
[0040] When in use, the sealing gasket 32 ensures the sealing between the sealing cover 31 and the connecting plate 13, blocks the cooling medium inside the connecting cover 2, and ensures that part of the heat exchange tube body 14 is detached from the connection cover 2. The sealing gasket 32 is made of a material resistant to seawater erosion to ensure the sealing effect and sealing material of the sealing gasket 32. Technical personnel can adjust and purchase the specific material according to actual on-site usage requirements.
[0041] To clean the heat exchange tube body 14, for example, Figure 2 As shown, a hose body 33 is plugged and installed on one side of the inner wall of the connection cover 2, and the other end of the hose body 33 is connected to the sealing cover 31, and the hose body 33 is communicated with the inside of the sealing cover 31.
[0042] When in use, the hose body 33 is set with a metal hose, and its surface has an anti-corrosion coating to maintain the service life of the hose body 33 inside the cooling medium, and the external dissolving liquid and cleaning liquid can enter the heat exchange tube body 14 through the hose body 33 and the sealing cover 31 to clean and flush the inside of the heat exchange tube body 14.
[0043] When the utility model is in use, the cooling medium is pressurized by the external liquid pump and transported to the inside of the second water pipe 21, and enters the inside of the connecting cover 2 through the second water pipe 21, so that the cooling medium circulates inside the heat exchange tube body 14 to cool the heat exchange tube body 14;
[0044] The heat exchange medium flows into the interior of the shell 1 through the first water pipe 12 and contacts the heat exchange tube body 14 , and the heat exchange tube body 14 allows the cooling medium to exchange heat with the heat exchange medium.
[0045] The push rod body 3 pushes the sealing cover 31 to move horizontally until the sealing pad 32 contacts the outer wall of the connecting plate 13, thereby ensuring the sealing between the sealing cover 31 and the connecting plate 13 and preventing the cooling medium inside the connecting cover 2 from continuing to enter the sealing cover 31;
[0046] An external liquid pump transports the dissolving liquid, enabling it to enter the interior of the heat exchange tube body 14 through the hose body 33 and the sealing cover 31, dissolving and cleaning the impurities adhering to the inner wall of the heat exchange tube body 14. The used dissolving liquid can be discharged through the hose body 33 at the other end. The external liquid pump transports the cleaning liquid, causing it to flow inside the heat exchange tube body 14 to rinse the dissolving liquid and maintain the relative cleanliness of the inner wall of the heat exchange tube body 14. Then, the push rod body 3 drives the sealing cover 31 to reset.
[0047] The motor body 23 drives the rotating shaft 22 and the connecting disc 13 to perform a circular rotation, flipping the position of the connecting disc 13, so that the un-cleaned heat exchange tube body 14 moves to one side of the sealing cover 31. By repeating the above cleaning steps, the entire heat exchange tube body 14 can be cleaned, ensuring that the heat exchange tube body 14 can be cleaned without the equipment shutting down.
