Description

Technical Field

[0001] This application relates to the technical field of cooling towers, and more particularly to a cooling tower with a heat exchange layer assembly. Background Technology

[0002] Currently, cooling towers are a type of heat exchange equipment widely used in industries such as power, chemical, metallurgy, and air conditioning. They are mainly used to discharge waste heat from industrial circulating water into the atmosphere through evaporation and convection, thereby reducing the water temperature and achieving recycling.

[0003] The cooling tower in the relevant technology mainly includes a fan system, a spray system, a heat exchange layer, a packing layer and a water tank arranged from top to bottom; the heat exchange layer is connected to a hot medium inlet pipe and a cold medium outlet pipe.

[0004] However, existing cooling towers only have one heat exchange layer. When the current heat exchange layer is damaged, the tower needs to be shut down for maintenance, which requires a long downtime. Since existing cooling towers are generally connected to multiple devices, this can affect production. Utility Model Content

[0005] This application provides a cooling tower with a heat exchange layer assembly, which can reduce the impact on production when the currently used heat exchange layer is damaged, by adopting the following technical solution:

There are at least two heat exchange layers. Each heat exchange layer is detachably connected to the spray system via multiple sets of first connecting mechanisms, to each other via multiple sets of second connecting mechanisms, and to the packing layer via multiple sets of third connecting mechanisms. The first, second, and third connecting mechanisms have identical structures. Each heat exchange layer is detachably connected to a hot medium inlet pipe and a cold medium outlet pipe. The spray system includes a water supply mechanism for pumping water from the water tank into the spray system. The water supply mechanism includes a water pump, a water supply inlet pipe connected to the water pump inlet, and a water supply outlet pipe connected to the water pump outlet. The end of the water supply inlet pipe away from the water pump is connected to the water tank, and the end of the water supply outlet pipe away from the water pump is connected to the spray system. The water supply outlet pipe includes multiple pipes connected via flanges.

[0007] Preferably, the first connecting mechanism includes a connecting plate, the two ends of which are respectively bolted to the heat exchange layer and the outer shell of the spray system.

[0010] Preferably, the insertion rod is fixed to the through hole by a fastening nut.

[0011] Preferably, both sides of the spray system and the heat exchange layer are equipped with hoisting components.

[0012] Preferably, each set of the lifting assembly includes a fixing plate and lifting rings mounted on the fixing plate.

[0013] Preferably, a threaded rod is fixedly connected to the bottom of the lifting ring, and a threaded hole is provided on the fixing plate, with the threaded rod threadedly connected to the threaded hole.

[0014] In summary, this application has the following beneficial effects:

[0015] When the heat exchange layer in use is damaged, the damaged heat exchange layer can be removed and replaced with a normal heat exchange layer to continue using it, thereby reducing the impact on production. Attached Figure Description

[0021] This application discloses a cooling tower with a heat exchange layer assembly, such as Figure 1 As shown, it includes, from top to bottom, a fan system 1, a spray system 2, a heat exchange layer 3, a packing layer 4, and a water tank 5.

[0022] like Figure 1 As shown, there are at least two heat exchange layers 3. In this embodiment, there are two heat exchange layers 3. The heat exchange layers 3 are detachably connected to the spray system 2 through multiple sets of first connecting mechanisms 6. The heat exchange layers 3 are detachably connected to each other through multiple sets of second connecting mechanisms. The heat exchange layers 3 are detachably connected to the packing layer 4 through multiple sets of third connecting mechanisms. Each heat exchange layer 3 is detachably connected to a hot medium inlet pipe 31 and a cold medium outlet pipe 32. The spray system 2 includes a water supply mechanism for pumping water from the water tank 5 into the spray system 2. The water supply mechanism includes a water supply pump 21, a water supply inlet pipe 22 connected to the inlet of the water supply pump 21, and a water supply outlet pipe 23 connected to the outlet of the water supply pump 21. The end of the water supply inlet pipe 22 away from the water supply pump 21 is connected to the water tank 5, and the end of the water supply outlet pipe 23 away from the water supply pump 21 is connected to the spray system 2. The water supply outlet pipe 23 includes multiple pipes connected by flanges. When the currently used heat exchange layer 3 is damaged, the damaged heat exchange layer 3 can be directly removed and connected to a normal heat exchange layer 3 for continued use, thereby reducing the impact on production.

[0023] like Figure 1 As shown, the first connecting mechanism 6, the second connecting mechanism, and the third connecting mechanism have the same structure. The structure of the first connecting mechanism 6 will be described in detail here, while the structures of the second and third connecting mechanisms will not be repeated. The first connecting mechanism 6 includes a connecting plate 61, the two ends of which are respectively bolted to the heat exchange layer 3 and the outer shell of the spray system 2 by multiple bolts. The connecting plate 61 and the multiple bolts facilitate detachable connections between the heat exchange layer 3 and the spray system 2, between heat exchange layers 3, and between the heat exchange layer 3 and the packing layer 4.

[0024] like Figure 1 and Figure 2 As shown, multiple sets of first positioning mechanisms 7 are provided between the heat exchange layer 3 and the spray system 2, multiple sets of second positioning mechanisms are provided between the heat exchange layers 3, and multiple sets of third positioning mechanisms are provided between the heat exchange layer 3 and the packing layer 4. The provided first positioning mechanisms 7, second positioning mechanisms, and third positioning mechanisms can improve the stability of the cooling tower.

[0025] like Figure 1 and Figure 2 As shown, the first positioning mechanism 7, the second positioning mechanism, and the third positioning mechanism have the same structure. The structure of the first positioning mechanism 7 will be described in detail here, and the structures of the second and third positioning mechanisms will not be described again. The first positioning mechanism 7 includes a first positioning plate 71 and a second positioning plate 72, which are respectively fixed to the heat exchange layer 3 and the outer shell of the spray system 2. A rod 711 is fixed to the bottom of the first positioning plate 71, and a through hole 721 is provided on the second positioning plate 72, into which the rod 711 is inserted. When the heat exchange layer 3 is connected to the spray system 2, the rod 711 is inserted into the through hole 721, which improves the stability between the heat exchange layer 3 and the spray system 2.

[0026] like Figure 1 and Figure 2 As shown, the insertion rod 711 is fixed to the through hole 721 by the fastening nut 73. The fastening nut 73 is threaded to the side wall of the insertion rod 711. The fastening nut 73 can improve the stability of the first positioning mechanism 7, thereby further improving the stability between the heat exchange layer 3 and the spray system 2.

[0027] like Figure 1 and Figure 3 As shown, both sides of the spray system 2 and the heat exchange layer 3 are equipped with lifting assemblies 8. The lifting assemblies 8 facilitate the disassembly of the spray system 2 and the heat exchange layer 3.

[0028] like Figure 1 and Figure 3 As shown, each hoisting assembly 8 includes a fixing plate 81 and a lifting ring 82 installed on the fixing plate 81. The fixing plate 81 is detachably connected to the outer shell of the spray system 2 or the heat exchange layer 3 by bolts. The lifting ring 82 facilitates the movement of the spray system 2 or the heat exchange layer 3. A threaded rod 821 is fixedly connected to the bottom of the lifting ring 82. A threaded hole 811 is opened on the fixing plate 81, and the threaded rod 821 is threadedly connected to the threaded hole 811. The threaded rod 821 and the threaded hole 811 facilitate the installation of the lifting ring 82.
