That is, the features with "first" and "second" can explicitly or implicitly include one or more of the features. In addition, unless otherwise stated, the meaning of "multiple" is two or more.

[0031] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0032] As shown in Figures 1-5 The air flow processing device for a ship engine room provided by the embodiment of the present application includes a first muffler 1, a second muffler 2, a column body 3, a first heat exchange assembly 4, a second heat exchange assembly 5, and a heat exchange pipe 6. The second muffler 2 is arranged in the first muffler 1 along the axial direction of the first muffler 1; the column body 3 is arranged in the second muffler 2 along the axial direction of the second muffler 2; the first heat exchange assembly 4 is installed between the first muffler 1 and the second muffler 2; the second heat exchange assembly 5 is installed between the second muffler 2 and the column body 3; the heat exchange pipe 6 has a heat exchange medium inside; the outer wall of the heat exchange pipe 6 abuts against the first heat exchange assembly 4 and the second heat exchange assembly 5, respectively; the heat exchange pipe 6 is used for heat exchange with the first heat exchange assembly 4 and the second heat exchange assembly 5; and the heat exchange pipe 6 has an inlet end 61 and an outlet end 62 arranged at two ends thereof, respectively, and the inlet end 61 and the outlet end 62 extend out of the outer wall of the first muffler 1.

[0033] Based on the above structure, the first heat exchange assembly 4 is installed between the first muffler 1 and the second muffler 2, and the second heat exchange assembly 5 is installed between the second muffler 2 and the column body 3, so that the first muffler 1 and the second muffler 2 can exchange heat with the first heat exchange assembly 4 and the second heat exchange assembly 5 when air flow is input into the ship engine room; the outer wall of the heat exchange pipe 6 abuts against the first heat exchange assembly 4 and the second heat exchange assembly 5, respectively, so as to exchange heat with the heat exchange medium inside the heat exchange pipe 6, and finally the temperature of the air flow input into the engine room is adjusted to meet the requirement of the ship engine room for air temperature.

[0034] In use, the device of the present application is installed in the pipeline conveying air to the engine room of the ship. When the air temperature of the engine room of the ship is too high, the heat exchange pipe 6 is connected to the central cooling water system of the ship, and the first heat exchange assembly 4 and the second heat exchange assembly 5 cool the air flow through heat exchange; when the air temperature of the engine room of the ship is too low, the heat exchange pipe 6 is connected to the hot water, hot steam, hot oil and other media of the ship, and the first heat exchange assembly 4 and the second heat exchange assembly 5 heat the air flow through heat exchange.

[0035] As shown in Figure 3 , the first silencer 1 includes a shell 11, a first silencer hole plate 12 arranged on the inner side of the shell 11, and a first silencer cotton layer 13 filled between the shell 11 and the first silencer hole plate 12, and the two ends of the first silencer hole plate 12 are fixedly connected with the inner wall of the shell 11. The above structure makes the first silencer 1 have the function of silencing and reducing noise.

[0036] In one embodiment, one end of the shell 11 is provided with a reducing joint 14 and a connecting flange 15, the connecting flange 15 is connected with the shell 11 through the reducing joint 14, and the diameter of the shell 11 is larger than the diameter of the connecting flange 15, so as to ensure that the shell 11 has sufficient flow area to adapt to the fan pipeline. By connecting the connecting flange 15 with the fan pipeline, the device of the present application can input air flow to the engine room of the ship.

[0037] As shown in Figure 3 , the second silencer 2 includes a second silencer hole plate 21, a third silencer hole plate 22 arranged on the inner side of the second silencer hole plate 21, and a second silencer cotton layer 23 filled between the second silencer hole plate 21 and the third silencer hole plate 22, and the two ends of the second silencer hole plate 21 are fixedly connected with the two ends of the third silencer hole plate 22. The above structure makes the second silencer 2 have the function of silencing and reducing noise.

[0038] As shown in Figure 4 , in one embodiment, the first heat exchange assembly 4 includes first heat exchange fins 41, two first heat conduction plates 42 and two first ear plates 43 mounted on both ends of the first heat exchange fins 41, the first heat conduction plates 42 are arranged between the first heat exchange fins 41 and the first ear plates 43, and the first heat exchange fins 41 and the first heat conduction plates 42 are respectively detachably connected with the first ear plates 43, for example, connected by bolts. One of the first ear plates 43 is fixed to the inner wall of the first silencer 1, and the other first ear plate 43 is fixed to the outer wall of the second silencer 2. In use, heat exchange occurs between the air flow, the first heat exchange fins 41, the first heat conduction plates 42 and the heat exchange pipe 6.

[0039] Specifically, the first heat exchange assembly 4 also includes a first connecting plate 44, which is located on the side of the first heat exchange plate 41 away from the first heat conducting plate 42, and the first connecting plate 44 is detachably connected to the first ear plate 43, for example, by bolts. The function of the first connecting plate 44 is to maintain the structural stability between the first silencer 1 and the second silencer 2.

[0040] To reduce air resistance, the ends of the two first heat-conducting plates 42 that are away from the first heat exchange plate 41 extend into the first sound-absorbing cotton layer 13 and the second sound-absorbing cotton layer 23, respectively, and abut against the heat exchange tubes 6 located in the first sound-absorbing cotton layer 13 and the second sound-absorbing cotton layer 23. The heat exchange tubes 6 adopt a U-shaped bending structure to be respectively set in the first sound-absorbing cotton layer 13 and the second sound-absorbing cotton layer 23.

[0041] like Figure 4 As shown, in one embodiment, the second heat exchange assembly includes a second heat exchange plate 51, two second heat-conducting plates 52 mounted at both ends of the second heat exchange plate 51, and two second ear plates 53. The second heat-conducting plates 52 are disposed between the second heat exchange plate 51 and the second ear plates 53, and the second heat exchange plate 51 and the second heat-conducting plates 52 are detachably connected to the second ear plates 53 respectively. One of the second ear plates 53 is fixed to the inner wall of the second silencer 2, and the other second ear plate 53 is fixed to the surface of the column 3. In use, heat exchange occurs between the airflow, the second heat exchange plate 51, the second heat-conducting plates 52, and the heat exchange tube 6.

[0042] Specifically, the second heat exchange assembly also includes a second connecting plate 54, which is located on the side of the second heat exchange plate 51 away from the second heat conduction plate 52, and is detachably connected to the second ear plate 53. The function of the second connecting plate 54 is to maintain the structural stability between the second silencer 2 and the column 3.

[0043] To reduce air resistance, the ends of the two second heat-conducting plates 52 furthest from the second heat exchange plate 51 extend into the second sound-absorbing cotton layer 23 and the guide post 3, respectively, and abut against the heat exchange tubes 6 located in the second sound-absorbing cotton layer 23 and the guide post 3. The heat exchange tubes 6 are arranged in the second sound-absorbing cotton layer 23 and the guide post 3 using a U-shaped bending structure.

[0044] like Figure 2 and Figure 3As shown, in one embodiment, the heat exchange pipe 6 is arranged in such a way that one end of the inlet end 61 extends from the shell 11 into the first sound-absorbing cotton layer 13 and communicates with the heat exchange pipe 6. The heat exchange pipe 6 extends vertically downward along the first sound-absorbing cotton layer 13 to the lower part of the first sound-absorbing cylinder 1, and then extends horizontally towards the second sound-absorbing cylinder 2 through the second sound-absorbing hole plate 21 into the second sound-absorbing cotton layer 23. The heat exchange pipe 6 extends vertically upward along the bottom of the second sound-absorbing cotton 23, and then extends downward in a reverse U shape to the bottom of the second sound-absorbing cotton 23. The heat exchange pipe 6 extends horizontally from the bottom of the second sound-absorbing cotton 23 into the column 3. The heat exchange pipe 6 extends vertically upward along the bottom of the column 3, and then extends downward in a reverse U shape to the bottom of the column 3. The heat exchange pipe 6 extends horizontally from the bottom of the column 3, and is arranged in the same way as described above from the column 3 into the first sound-absorbing cotton layer 13 and communicates with one end of the outlet end 61. By arranging the heat exchange pipe 6 in the first sound-absorbing cotton layer 13, the second sound-absorbing cotton layer, and the column 3, the air flow resistance can be reduced, and the exhaust can be smooth.

[0045] To further reduce the resistance of the heat exchange pipe 6 to the air flow, when the heat exchange pipe 6 extends horizontally towards the second sound-absorbing cylinder 2 through the second sound-absorbing hole plate 21 into the second sound-absorbing cotton layer 23, the part of the heat exchange pipe 6 between the first sound-absorbing cylinder 1 and the second sound-absorbing cylinder 2 is in the same plane as the first heat exchange assembly 4 along the axis of the column 3. When the heat exchange pipe 6 extends horizontally from the bottom of the second sound-absorbing cotton 23 into the column 3, the part of the heat exchange pipe between the second sound-absorbing cylinder 2 and the column 3 is in the same plane as the second heat exchange assembly 5 along the axis of the column 3.

[0046] It should be noted that during the arrangement of the heat exchange pipe 6, it can be distributed circumferentially along the inside of the column 3 and the inside of the first sound-absorbing cotton layer 23, thereby extending the length of the heat exchange pipe 6 to improve the heat exchange efficiency.

[0047] The above description is only the preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and replacements without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
