Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a corrosion-resistant cooling tower suitable for both dry and wet applications. Background Technology

[0002] Traditional dry cooling towers (air-cooled islands) and wet cooling towers differ significantly in size due to their different heat transfer principles. The heat exchange area of ​​a traditional dry cooling tower is over a hundred times larger than that of a wet cooling tower. Traditional closed-circuit cooling towers are a product between dry and wet cooling towers. However, their heat exchange principle remains the same as wet cooling towers. They simply have an additional layer of coils to isolate the two circulation loops between the user end and the heat dissipation end. Therefore, when a closed-circuit tower is used as a dry cooling tower in winter, its heat dissipation performance falls far short of the required cooling capacity.

[0003] Traditional closed-loop cooling towers mostly use metal heat exchange coils. When the cooling medium is corrosive, most metals cannot withstand the stress, and even expensive titanium materials cannot operate safely and stably when faced with certain corrosive media.

[0004] Traditional coils are all fixed installations. Due to the characteristics of plastics—low modulus, large plastic deformation, and a relatively large coefficient of thermal expansion—in environments like cooling towers where the temperature difference can reach tens of degrees Celsius, traditional plastic coil devices can deform and become clogged due to plastic deformation and thermal expansion, blocking air ducts or causing structural failure. This leads to unstable equipment operation. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes a corrosion-resistant cooling tower that can be used for both wet and dry applications. The cooling tower coils in this invention are made of plastic. Given that the thermal conductivity of plastic differs from that of metal by nearly a thousand times, a dense U-shaped coil array is used to achieve the required cooling and heat exchange performance of the cooling tower. The surface area of ​​the U-shaped plastic coils is essentially equivalent to the surface area of ​​the packing material in traditional cooling towers. Therefore, it can be used as a wet closed-loop cooling tower in the hot summer. In the cold winter, due to the sufficiently large surface area of ​​the coils and excellent heat dissipation performance, it can be used as a dry cooling tower, thus achieving the goals of energy and water conservation.

[0007] This utility model proposes a corrosion-resistant cooling tower suitable for both dry and wet applications, including a tower frame structure. The top of the tower frame structure is provided with a local circulation water inlet. The tower frame structure is connected to an enclosure panel.

[0011] By adopting the above technical solution, the combination of cooling components and water spraying components can effectively improve the cooling effect of the device. The combination of the enclosure panel and the tower frame structure can improve the overall structural rigidity of the device, thereby making the device stable in supporting the U-shaped coil.

[0012] Preferably, the bottom of the tower frame structure is connected to a base support beam, the bottom of the base support beam is connected to a structural support column, the bottom of the structural support column is in contact with the ground, and the end of the coil away from the local circulation water inlet is connected to the coil system water inlet.

[0013] By adopting the above technical solution, this solution can improve the support stability of the bottom of the device through the bottom basin support beam and structural support column.

[0014] Preferably, an automatic water replenishment ball valve is connected to the bottom of the basin support beam, the automatic water replenishment ball valve is connected to the coil, the other end of the automatic water replenishment ball valve is connected to a local circulation pump group, and an automatic water replenishment pipe is connected through the side of the automatic water replenishment ball valve.

[0015] By adopting the above technical solutions, this solution can achieve automatic water replenishment to the inside of the coil and U-shaped tube through the combination of automatic water replenishment ball valve and local circulating pump group. This enables the automatic replenishment of circulating water during the cooling cycle, ensuring stable water pressure inside the pipeline. The combination of fan and air duct enables the air cooling effect of the device, thereby improving the cooling processing efficiency of the device. The combination of water spray tray and water spray nozzle enables water cooling of the U-shaped tube, thereby improving the cooling effect of the U-shaped coil.

[0016] Preferably, the tower frame structure is connected to a U-shaped tube support, the U-shaped tube support is connected to a U-shaped capillary tube, the water spray nozzle faces the direction of the U-shaped capillary tube, one end of the U-shaped capillary tube is connected to a coil system distributor, and the other end of the U-shaped capillary tube is connected to the coil.

[0017] By adopting the above technical solution, this solution can achieve the connection support stability of the U-shaped tube through the U-shaped tube bracket.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] The U-shaped plastic coils in this case are made of non-metallic materials, exhibiting excellent corrosion resistance. They can withstand various acid and alkali corrosive media, ensuring stable system operation. Especially in areas where the quality of reclaimed water is very poor and conventional water sources cannot meet the needs, this cooling tower can be used as a high-salt wastewater cooling tower, solving both the energy consumption problem of high-salt water concentration and the water shortage problem of traditional cooling towers. It has excellent application scenarios.

[0022] The coil designed in this patent uses a U-shaped structure fixed at the top. The U-shaped capillary hangs vertically under its own weight. When the coil deforms, it can extend freely downwards without forming a disordered structure that stacks and blocks the airflow.

[0023] Vertically suspended U-shaped coils, due to their relatively large degree of freedom, will sway to some extent under the influence of wind. This swaying, to a certain extent, helps to address the issue of cleaning the coil surface, thus ensuring the long-term stable operation of the entire system. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-6The present invention will be described in further detail below. Example

[0033] like Figures 1-6 As shown, in order to solve the existing problems, this utility model discloses a dry and wet dual-use corrosion-resistant cooling tower, including a tower frame structure 1, a protective panel 3 connected to the tower frame structure 1, a coil inside the protective panel 3, a local circulation water inlet 2 at one end of the coil, a coil system water outlet 4 on the outer arc side of the coil, a pipe support on the outer arc side of the coil, the other end of the pipe support connected to the tower frame structure 1, a cooling component 14 connected to the top of the tower frame structure 1, a water spray component 15 connected to the top of the tower frame structure 1, and an inspection door 6 rotatably connected to the side of the protective panel 3.

[0034] The bottom of the tower frame structure 1 is connected to a bottom basin support beam 7, the bottom of the bottom basin support beam 7 is connected to a structural support column 8, the bottom of the structural support column 8 is in contact with the ground, and the end of the coil away from the local circulation water inlet 2 is connected to the coil system water inlet 5.

[0035] The bottom of the basin support beam 7 is connected to an automatic water replenishment ball valve 9, which is connected to the coil. The other end of the automatic water replenishment ball valve 9 is connected to a local circulation pump group 13, and an automatic water replenishment pipe 12 is connected through the side of the automatic water replenishment ball valve 9.

[0036] The cooling component 14 includes a motor 1401 connected to the top of the tower frame structure 1. A reducer 1402 is connected to the bottom output end of the motor 1401. A fan 1403 is connected to the other end of the reducer 1402. A duct 1404 is connected to the tower frame structure 1. The fan 1403 is disposed inside the duct 1404 and is rotatably connected inside the duct 1404. An air outlet is provided on the side of the duct 1404 facing the coil.

[0037] The water spraying component 15 includes a diverter 1502 connected to the top of the tower frame structure 1. The top of the diverter 1502 is provided with a circulating water inlet 1501, and the bottom of the diverter 1502 is connected to a water spraying plate 1503. The bottom of the water spraying plate 1503 is connected to a plurality of equally spaced water spraying nozzles 1504.

[0038] The U-shaped tube support frame 1507 has a U-shaped coil water inlet pipe 10 and a U-shaped coil water return pipe on its side. The U-shaped coil water inlet pipe 10 and the U-shaped coil water return pipe 11 are respectively connected to the two ends of the U-shaped capillary tube 1506.

[0039] The specific working principle is as follows: This device can achieve the cooling effect of cooling tower. The device uses circulating water to transfer heat by flowing inside the U-shaped coil. When passing under the air-cooling and water-spraying components 15, it performs air-cooling and water-cooling processes. Then, the water temperature inside the pipe is reduced by heat radiation from the U-shaped coil. The low-temperature water is then flowed back into the cooling tower, thus achieving the heat transfer and cooling effect of this device. The use of water to carry heat can improve the efficiency of heat transfer.

[0040] When this device is in use, it connects the U-shaped capillary tube 1506 and the coil to the cooling tower, thereby introducing the cooling water in the cooling tower into the U-shaped capillary tube 1506 and the coil for circulation. During the circulation process, the automatic water replenishment ball valve 9 at the bottom of the device and the local circulation pump group 13 can maintain the water pressure inside the pipe by injecting water from the outside, thereby ensuring the stability of the circulating cooling of this device.

[0041] During the water circulation process of this device, the U-shaped capillary 1506 can be air-cooled by the cooling component 14. The fan 1403 can be rotated inside the air duct 1404 by the motor 1401 driving the reducer 1402, thereby generating air force. The airflow is discharged through the air outlet on the side of the air duct 1404, thereby achieving the effect of air-cooling the U-shaped capillary 1506 of this device.

[0042] Meanwhile, this device can achieve water cooling of the U-shaped capillary tube 1506 through the water spray component 15. By connecting the circulating water inlet 1501 to the external water source, the external water source can flow through the distributor 1502 and the water spray plate 1503 to each water spray nozzle 1504, thereby achieving the effect of water flow dispersion. The dispersed water flow can contact the outer arc surface of the U-shaped capillary tube 1506, thereby achieving the effect of heat exchange. Finally, the water flow is recovered from the bottom basin support beam 7. Example

[0043] like Figures 1-6 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the first embodiment above, the dual-purpose dry and wet corrosion-resistant cooling tower further includes: the tower frame structure 1 is connected to a U-shaped tube support, the U-shaped tube support is connected to a U-shaped capillary tube 1506, the water spray nozzle 1504 faces the U-shaped capillary tube 1506, one end of the U-shaped capillary tube 1506 is connected to a coil system distributor 1505, and the other end of the U-shaped capillary tube 1506 is connected to the coil.

[0044] The bottom basin support beam 7 is connected to a U-shaped tube support frame 1507. The U-shaped tube support frame 1507 is connected to the bottom of the U-shaped capillary tube 1506. A branch pipe is provided on the outer arc side of the bottom of the U-shaped capillary tube 1506. The branch pipe is provided with a circulation outlet 1508. The bottom of the U-shaped capillary tube 1506 hangs freely. An arc-shaped return water pipe is provided at the bottom of the U-shaped capillary tube 1506.

[0045] This device has the following beneficial effects:

[0046] 1. A U-shaped capillary coil made of non-metallic composite material is fixedly installed on the tower structure. The U-shaped capillary coil is suspended vertically under the action of gravity.

[0047] 2. Local circulating water enters the distributor through the inlet. It is then distributed to the spray tray 1503 and sprayed onto the inlet and return water branch pipes of the U-shaped coil via nozzles. On the net return water branch pipe, laminar flow causes it to flow along the U-shaped capillary tube 1506 into the collection tray below. As the local circulating water passes over the surface of the U-shaped capillary tube 1506, it interacts with the airflow entering the cooling tower, resulting in heat exchange and evaporation. This heat exchange and evaporation ultimately removes heat from the water in the U-shaped capillary coil. The heat in the U-shaped capillary coil is conducted away through the tube wall, but the water does not evaporate.

[0048] 3. The local circulating water is highly saline, but may also be other highly corrosive and non-volatile solutions. Through system makeup and drainage, this local circulating water ensures that the concentrated water remains below saturation, thus maintaining normal system operation.

[0049] 4. All components of the tower body that come into contact with water, including U-shaped coils, inlet water distributors, return water collectors, chassis, columns, beams, maintenance walkways, enclosure panels, 1503 water spray trays, nozzles, inlet pipes, pump sets, valves, and return water pipes, are made of corrosion-resistant polymer materials.

[0050] The fan 1403, motor 1401 and reducer 1402 are all protected against corrosion with a highly corrosion-resistant anti-corrosion coating.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
