Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a large-scale antifreeze counterflow cooling tower. Background Technology

[0002] Cooling towers are essential equipment in industrial production and refrigeration and air conditioning systems. They dissipate heat from circulating water through heat exchange between water and air to ensure the normal operation of the system. For large counter-flow cooling towers, there is a problem of equipment freezing damage due to low temperatures in cold regions or winter conditions.

[0003] Existing antifreeze measures, such as adding electric heat tracing, can prevent icing to some extent, but they consume a lot of energy and have high operating costs. Traditional methods of adjusting air intake with louvers have limited antifreeze effects and cannot meet the antifreeze requirements of large cooling towers under extreme low-temperature conditions. At the same time, existing cooling towers also have certain irrationalities in air distribution and water flow distribution, resulting in heat exchange efficiency that needs to be improved and local icing and blockages that are prone to occur, affecting the normal operation and service life of the cooling tower. Therefore, it is necessary to improve large counterflow cooling towers to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a large-scale antifreeze counterflow cooling tower to solve the problems of existing large-scale counterflow cooling towers being prone to icing, having poor antifreeze effect, and low heat exchange efficiency under cold conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large anti-freezing counter-flow cooling tower, comprising a cooling tower body, a water collection tank connected to the bottom of the cooling tower body, a packing layer installed inside the cooling tower body, a water distribution pipe installed above the packing layer, spray nozzles arranged at the bottom of the water distribution pipe, a heating plate fixedly installed at the bottom of the inner cavity of the water collection tank, a heating pipe annularly installed outside the heating plate and in the inner wall of the water collection tank, a temperature sensor installed on one side of the heating pipe, and a water inlet pipe connected to the right side of the water collection tank, the upper end of the water inlet pipe being connected to the water distribution pipe.

[0006] As a preferred embodiment, a fixing sleeve is fitted around the middle end of the water inlet pipe, a heating pad is installed inside the fixing sleeve, and a rubber support pad is annularly installed around the heating pad, with the outer end of the rubber support pad connected to the inner wall of the fixing sleeve.

[0007] As a preferred embodiment, sealing caps are fixedly installed at both the upper and lower ends of the fixed sleeve, and the sealing caps are sleeved on the surface of the water inlet pipe and make sealing contact.

[0008] As a preferred embodiment, an auxiliary return pipe is connected to one side of the upper end of the water inlet pipe, the lower end of the auxiliary return pipe is connected to the interior of the water collection tank, and a regulating valve is movably installed on the surface of one end of the auxiliary return pipe.

[0009] As a preferred embodiment, a heating component is fixedly installed at the bottom of the cooling tower body, and the control terminal of the heating component is connected to the heating pipe and the heating plate.

[0010] As a preferred embodiment, the packing layer uses corrugated packing arranged at equal intervals, and the temperature sensor is connected to an external control terminal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a heating plate installed at the bottom of the inner cavity of the water collection tank to directly heat the water at the bottom of the tank, preventing the bottom water from freezing due to excessively low temperature. At the same time, heating pipes installed in a ring around the inner wall of the water collection tank can heat the water around the tank. This three-dimensional heating layout ensures that the water in the water collection tank is heated evenly, effectively preventing localized low temperature freezing. The temperature sensor can monitor the water temperature in the water collection tank in real time and provide timely feedback. When the water temperature approaches the freezing point or falls below the set safe temperature, it can automatically adjust the power of the heating pipes to achieve precise heating, ensuring that the water in the water collection tank does not freeze and avoiding energy waste caused by overheating.

[0013] 2. This utility model connects the control terminal of the heating component to the heating tube and heating plate, enabling unified control of the heating tube and heating plate. This means that the heating component can adjust the working state and power of the heating tube and heating plate simultaneously according to actual needs, allowing the water in the collection tank to heat up more quickly and evenly. This avoids problems such as uneven heating and low efficiency that may occur when different heating devices work alone, and greatly improves the overall antifreeze effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0021] Please see Figure 1 As shown, this utility model provides a large anti-freezing counterflow cooling tower, including a cooling tower body 1, a water collection tank 2 connected to the bottom of the cooling tower body 1, a packing layer 3 installed inside the cooling tower body 1, a water distribution pipe 8 installed above the packing layer 3, spray nozzles 9 arranged at the bottom of the water distribution pipe 8, a heating plate 4 fixedly installed at the bottom of the inner cavity of the water collection tank 2, a heating pipe 5 annularly installed outside the heating plate 4 and located in the inner wall of the water collection tank 2, a temperature sensor 6 installed on one side of the heating pipe 5, and a water inlet pipe 7 connected to the right side of the water collection tank 2, the upper end of the water inlet pipe 7 being connected to the water distribution pipe 8.

[0022] This technical solution uses a heating plate 4 installed at the bottom of the inner cavity of the water collection tank 2 to directly heat the water at the bottom of the water collection tank 2, preventing the bottom water from freezing due to excessively low temperature. At the same time, the heating pipe 5 installed in a ring in the inner wall of the water collection tank 2 can heat the water around the water collection tank 2. This three-dimensional heating layout allows the water in the water collection tank 2 to be heated evenly, effectively preventing the occurrence of local low temperature freezing. The temperature sensor 6 can monitor the water temperature in the water collection tank 2 in real time and provide timely feedback on the temperature information. When the water temperature is close to the freezing point or lower than the set safe temperature, it can automatically adjust the power of the heating pipe 5 to achieve precise heating, which not only ensures that the water in the water collection tank 2 will not freeze, but also avoids energy waste caused by overheating. Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, a fixed sleeve 10 is sleeved on the outside of the middle end of the water inlet pipe 7. A heating pad 11 is installed inside the fixed sleeve 10. A rubber support pad 12 is annularly installed on the outside of the heating pad 11. The outer end of the rubber support pad 12 is connected to the inner wall of the fixed sleeve 10.

[0024] Adopting such Figure 1 The technical solution shown allows the heating pad 11 installed inside the fixed sleeve 10 to directly heat the water inlet pipe 7, ensuring that the water in the pipe can maintain a certain temperature even in low-temperature environments. This prevents the water in the water inlet pipe 7 from freezing due to cold environments, ensuring the normal operation of the cooling tower water circulation system. The heating pad 11 can continuously heat the water inlet pipe 7, keeping the water temperature in the pipe always above the freezing point, providing a reliable guarantee for the antifreeze of the entire cooling tower.

[0025] Secondly, in the technical solution, sealing caps 13 are fixedly installed at both the upper and lower ends of the fixed sleeve 10. The sealing caps 13 are sleeved on the surface of the water inlet pipe 7 and make sealing contact. An auxiliary return pipe 14 is connected to one side of the upper end of the water inlet pipe 7. The lower end of the auxiliary return pipe 14 is connected to the interior of the water collection tank 2. A regulating valve 15 is movably installed on the surface of one end of the auxiliary return pipe 14.

[0026] Its adoption is as follows Figure 1 The technical solution shown allows the sealing cap 13 to seal the upper and lower ends of the fixed sleeve 10, preventing internal heat leakage. The auxiliary return pipe 14 and the regulating valve 15 can open the regulating valve 15 in low-temperature environments, allowing some of the hot water inside the inlet pipe 7 to flow directly back into the water collection tank 2, preventing freezing and blockage in low-temperature environments and reducing damage to the water distribution pipe 8. Example

[0027] This utility model is as follows Figures 1-4 As shown, a heating component is fixedly installed at the bottom of the cooling tower body 1, and the control terminal of the heating component is connected to the heating pipe 5 and the heating plate 4; the packing layer 3 adopts corrugated packing arranged at equal intervals, and the temperature sensor 6 is connected to an external control terminal.

[0028] By adopting the above technical solution, the control end of the heating component is connected to the heating tube 5 and the heating plate 4, which enables unified control of the heating tube 5 and the heating plate 4. This means that the heating component can adjust the working status and power of the heating tube 5 and the heating plate 4 simultaneously according to actual needs, so that the water in the water collection tank 2 can be heated more quickly and evenly. This avoids problems such as uneven heating and low efficiency that may occur when different heating devices work alone, and greatly improves the overall antifreeze effect.

[0029] The working principle of this utility model is as follows: In terms of antifreeze, the heating plate 4 at the bottom of the inner cavity of the water collection tank 2 and the annular heating pipe 5 in the inner wall heat the water in the water collection tank 2 under the unified control of the heating component. The heating component intelligently adjusts the heating power based on the water temperature data fed back to the external control terminal by the temperature sensor 6 to ensure that the water temperature is suitable. The heating pad 11 on the outside of the middle end of the water inlet pipe 7 can also heat the water flow in the pipe. The rubber support pad 12 plays a supporting and buffering role. When the water flow in the water inlet pipe 7 is not good, the auxiliary return pipe 14 can be adjusted by the regulating valve 15 to allow some water to return to the water collection tank 2, ensuring water circulation and temperature stability, thereby achieving efficient antifreeze operation of the entire cooling tower.
