Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a defogging cooling tower. Background Technology

[0002] Cooling towers are commonly used heat dissipation equipment in industrial production. Their efficiency and environmental performance have always been the focus of industry attention. Their function is to exchange heat between circulating water carrying waste heat and the air inside the tower, transferring the heat of the water to the air and dissipating it into the atmosphere, thereby cooling the circulating water.

[0003] During the use of cooling towers, the circulating water undergoes a phase change due to heat exchange with the air, generating a large amount of saturated water vapor rain at the air duct. This rain causes significant losses of circulating water, impacting factory operations and the working environment, road traffic safety, equipment corrosion in the factory's equipment area, and other aspects.

[0004] A prior art patent with publication number CN222651959U discloses a solution including a tower body. Inside the tower body, anti-fogging module groups and packing are arranged side-by-side from top to bottom. A module water distribution pipe is located above the anti-fogging module groups, and a packing water distribution pipe is located above the packing. The anti-fogging module groups include several parallel-arranged rhomboid anti-fogging modules. The inner cavity of each rhomboid anti-fogging module is connected to a hot channel and a cold channel, which are separated. Louvers connecting to the cold channel are provided on the side wall of the tower body, and a flap at the lower end of the cold channel is oscillating to control its opening and closing. By adding module water distribution pipes and rhomboid anti-fogging modules, the heat exchange efficiency of the cooling tower is improved, enabling increased cooling capacity or anti-fogging and water-saving functions under different operating modes.

[0005] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0006] Although existing defogging towers have improved the defogging effect and heat exchange efficiency, they still have problems such as small heat exchange area and insufficient defogging.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In view of the shortcomings of the prior art, this utility model provides a defogging cooling tower to solve the problems that, although existing defogging towers have improved the defogging effect and heat exchange efficiency, they still have small heat exchange area and insufficient defogging.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A defogging cooling tower includes a tower body. Inside the tower body, several vertically arranged baffles form several independent hot air channels and cold air channels. Several diamond-shaped defogging modules are arranged side-by-side inside the tower body. The inner cavity of each diamond-shaped defogging module connects to the independently arranged hot air channels and cold air channels. Packing material is located below each diamond-shaped defogging module, and a water distribution pipe is located above the packing material. The water distribution pipe has nozzles corresponding to the hot air channels and cold air channels respectively. The nozzles located within the cold air channels are equipped with electrically operated valves.

[0011] The baffle assembly includes an upper baffle and a lower baffle arranged side by side from top to bottom. An arc-shaped hole is provided on the opposite surface of the upper baffle and the lower baffle, and the water distribution pipe passes through the arc-shaped hole.

[0012] As an optimized solution, in winter operating mode, the nozzles in the cold air channel are closed, the nozzles in the hot air channel are open, and the louvers are open.

[0013] As an optimized solution, louvers are provided on the side wall of the tower body corresponding to each of the cold air channels.

[0014] As an optimized solution, the baffle is provided with an arc-shaped hole, and the water distribution pipe passes through the arc-shaped hole.

[0015] As an optimized solution, a sealing ring is provided between the arc-shaped hole and the water distribution pipe.

[0016] As an optimized solution, an axial flow fan is connected to the top of the tower.

[0017] As an optimized solution, an air inlet is provided on the side wall of the tower body below the packing.

[0018] As an optimized solution, a water collection pool is provided at the bottom of the tower.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] Compared to conventional cooling towers, this invention features spaced hot air and cold air channels connected within the inner cavity of the diamond-shaped defogging module, and an electric valve is installed on the nozzle of the lower surface of the packing water distribution pipe below the cold air channel. This invention's defogging cooling tower fully utilizes the internal space, increasing the heat exchange area and significantly improving heat exchange and defogging efficiency under different operating modes.

[0021] The diamond-shaped modules are stacked alternately to form a multi-channel defogging module. The module has alternating cold and hot channels inside, which are used to exchange heat between the humid and hot air that has completed heat exchange in the packing area below and the dry and cold air that enters the module through the louvers. It is mainly used to eliminate white fog in winter and recover water droplets in the humid and hot air, so as to achieve defogging and water saving.

[0022] Baffles are used to divide the area between the louvers and the filler into independent spaces, forming a hot and humid passage and a cold and dry passage.

[0023] The baffle uses an arc-shaped hole to connect to the water distribution pipe, and fills the contact area with the water distribution pipe with sealing rings or foam adhesive and other materials that can achieve a complete seal, thereby achieving a completely independent seal on both sides of the baffle.

[0024] In summer operating mode, both cold aisle nozzles and hot aisle nozzles are open, and the louvers are closed. At this time, the diamond-shaped anti-fog module passes through humid and hot air to achieve circulating water heat exchange.

[0025] In winter operating mode, the cold aisle nozzles are closed, the hot aisle nozzles are open, and the louvers are open. At this time, the hot aisle of the diamond module passes through humid and hot air, while the cold aisle passes through dry and cold air entering through the air inlet and louvers. The two exchange heat in the diamond module through a partition, achieving defogging and water saving.

[0026] Because the cold aisle nozzles are closed and the louvers are all open, two portions of cold air enter the defogging module simultaneously. Compared to existing technologies where only the louvers allow cold air to enter, the defogging and water-saving effects are more significant. Attached Figure Description

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] like Figure 1 As shown, the system includes a tower body 1. Inside the tower body 1, several vertically arranged baffles form several independent hot air channels 4 and cold air channels 3. Inside the tower body 1, several diamond-shaped anti-fogging modules 2 are arranged side by side. The inner cavity of each diamond-shaped anti-fogging module 2 is connected to the independently arranged hot air channels 4 and cold air channels 3. Below the diamond-shaped anti-fogging modules 2, there is a packing material 7. Above the packing material 7, there is a water distribution pipe 5. The water distribution pipe 5 is equipped with nozzles 6 corresponding to the hot air channels 4 and cold air channels 3, respectively. The nozzles 6 located in the cold air channels 3 are equipped with electric valves.

[0032] The baffle assembly includes an upper baffle 12 and a lower baffle 13 arranged side by side from top to bottom. Arc-shaped holes are opened on the opposite surfaces of the upper baffle 12 and the lower baffle 13, and the water distribution pipe passes through the arc-shaped holes.

[0033] In winter operating mode, nozzle 6 in cold air channel 3 is closed, nozzle 6 in hot air channel 4 is open, and louvers 11 are open.

[0034] The baffle is divided into upper and lower parts. The opening of the baffle is used to lock the water distribution pipe, so as to achieve a complete and sealed channel.

[0035] Louvers 11 are provided on the side wall of the tower body 1 corresponding to each cold air channel 3.

[0036] A sealing ring is provided between the arc-shaped hole and the water distribution pipe 5.

[0037] An axial flow fan 10 is connected to the top of the tower body 1.

[0038] An air inlet 8 is provided on the side wall of the tower body 1 below the packing 7.

[0039] A water collection pool 9 is provided at the bottom of the tower body 1.

[0040] The working principle of this device is as follows:

[0041] Compared with conventional cooling towers, the present invention has a hot air channel 4 and a cold air channel 3 connected at intervals in the inner cavity of the diamond-shaped defogging module 2, and an electric valve is installed on the nozzle 6 on the lower surface of the water distribution pipe 5 of the packing 7 below the cold air channel 3. The defogging cooling tower of the present invention makes full use of the space inside the tower, increases the heat exchange area, and can significantly improve the heat exchange and defogging efficiency in different operating modes.

[0042] The diamond-shaped modules are stacked alternately to form a multi-channel defogging module. The module has alternating cold and hot channels inside, which are used to exchange heat between the humid and hot air that has completed heat exchange in the packing zone 7 and the dry and cold air that enters the module through the louvers 11. This is mainly used to eliminate white fog in winter and recover water droplets in the humid and hot air, thus achieving defogging and water saving.

[0043] The baffle assembly is used to divide the area between the louver 11 and the filler 7 into independent spaces, forming a hot and humid passage and a cold and dry passage.

[0044] The baffle assembly uses an arc-shaped hole to connect the water distribution pipe 5, and fills the contact point with the water distribution pipe 5 with sealing rings or foam adhesive, etc., which can achieve a complete seal, thereby achieving a completely independent seal on both sides of the baffle assembly.

[0045] In summer working mode, both cold aisle nozzles 6 and hot aisle nozzles 6 are open, and louvers 11 are closed. At this time, the diamond-shaped anti-fog module 2 passes through humid and hot air to achieve circulating water heat exchange.

[0046] In winter working mode, the cold aisle nozzle 6 is closed, the hot aisle nozzle 6 is open, and the louver 11 is open. At this time, the hot aisle of the diamond module passes through humid and hot air, and the cold aisle passes through dry and cold air entering through the air inlet 8 and the louver 11. The two exchange heat in the diamond module through the wall, achieving defogging and water saving.

[0047] With the cold aisle nozzle 6 closed and the louvers 11 all open, two portions of cold air enter the defogging module simultaneously. Compared to existing technologies where only the louvers 11 allow cold air to enter, the defogging and water-saving effect is more significant.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
