Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to a composite device that combines spray humidification and heating coils for air coolers. Background Technology

[0002] In industrial production, air coolers are widely used in oil refining, chemical, and power industries to cool or condense process media. Their heat exchange performance is highly dependent on the temperature and humidity of the ambient air. In hot or arid regions during summer, the dry-bulb temperature of the ambient air rises significantly, leading to a decrease in the air cooler's heat dissipation capacity, making it difficult to meet the cooling load required by the process, and in severe cases, even causing the unit to overheat and shut down. To address this problem, existing technologies often employ a spray humidification system at the air cooler inlet, using water mist evaporation to lower the inlet air temperature, thereby improving heat exchange efficiency. However, such spray systems are usually independent add-ons with loose structures and lack integration with the air cooler itself.

[0003] On the other hand, in cold regions or during winter operation, excessively low ambient temperatures can increase the viscosity or even solidify the process media (such as heavy oils and high-pour-point liquids) inside the air cooler, leading to increased flow resistance, decreased heat exchange efficiency, and even tube blockage or rupture. To prevent such problems, some air coolers are equipped with electric heaters or steam tracing devices to preheat the intake air or tube bundles. However, existing heating solutions are mostly temporary or localized measures, lacking coordinated control with the cooling function. They often require additional space, increase energy consumption, and become redundant components during high-temperature seasons, resulting in resource waste and potential interference with normal airflow organization. More importantly, current air cooler auxiliary systems on the market generally set up "spray cooling" and "intake air heating" as two unrelated functional modules, resulting in complex equipment structures, fragmented control logic, high maintenance costs, and difficulty in achieving smooth switching and efficient coordination based on actual environmental conditions. Therefore, there is an urgent need for a composite auxiliary device that is compact in structure, integrates functions, and can automatically adapt its operating mode according to the ambient temperature, in order to solve the defects of existing technologies such as separate heating and cooling functions, poor adaptability, and insufficient reliability. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a composite device that combines spray humidification and heating coils for air coolers.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] A composite device combining spray humidification and heating coils for an air cooler, comprising:

[0007] There are two side beams, which are installed on both sides of the air inlet of the air cooler;

[0008] Heating tube array, installed on the upper part between the two side beams;

[0009] The spraying device is installed in the lower part between the two side beams;

[0010] Multiple support components are installed between two side beams; they are used to support or fix the heating pipe array and the spray device, respectively.

[0011] Preferably, the heating tube array is an electric heating tube.

[0012] Preferably, the heating tube array consists of multiple interconnected medium flow tubes, which are arranged at an angle.

[0013] Preferably, the spraying device includes:

[0014] Connecting pipes, which are multiple pipes spaced apart;

[0015] The atomizing nozzles are multiple nozzles spaced apart along the length of the connecting pipe, and the atomizing nozzles are connected to the connecting pipe.

[0016] Preferably, the atomizing nozzle is detachably connected to the connecting pipe.

[0017] Preferably, the support member includes:

[0018] There are two mounting plates, which are detachably connected to the two side beams respectively;

[0019] Angle iron, whose two ends are fastened to two mounting plates.

[0020] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0021] (1) This utility model has a simple structure. By integrating the spray humidification and heating pipes into the same structural frame, it achieves the organic unity of cooling and heating functions. Under high-temperature conditions, the spray system is activated to effectively reduce the inlet air temperature by water mist evaporation, thereby improving the heat exchange capacity of the air cooler. Under low-temperature conditions, it switches to heating mode to preheat the inlet air and prevent the process medium from freezing or increasing in viscosity. The two modes can be flexibly switched according to environmental conditions, which significantly enhances the air cooler's adaptability to complex climates throughout the year, ensures the continuous and stable operation of the process system, and helps maintain a constant outlet medium temperature, thereby improving overall energy efficiency and operational safety.

[0022] (2) The present invention uses two side beams to form the main support frame, with the heating pipes arranged at the top and the spraying device arranged at the bottom. The layout is reasonable and avoids mutual interference between functional components. At the same time, multiple support members are set between the side beams to reliably fix the heating pipes and the spraying device, which not only improves the overall structural rigidity, but also facilitates the installation, disassembly and daily maintenance of the components, and enhances the reliability and operability of the equipment in long-term operation.

[0023] (3) The heating pipe of this utility model can adopt two structural forms: electric heating tube or medium flow pipe, to meet the needs of different application scenarios. The electric heating tube solution does not require an external heat source, has a rapid control response, and is suitable for occasions with good power conditions; the medium flow pipe can utilize the waste heat resources of the factory to achieve energy-saving operation. In particular, the medium flow pipe adopts an inclined arrangement, which is conducive to draining the internal residual liquid after shutdown, effectively avoiding the risk of freezing and corrosion, and accelerating the thermal response speed when the system restarts.

[0024] (4) The spray device of this utility model consists of multiple connecting pipes and atomizing nozzles arranged at intervals. The connecting pipes form a uniform water supply network through series and parallel connection, ensuring that the entire air inlet section receives consistent spray coverage, avoiding local over-humidification or cooling blind spots, improving evaporation efficiency and reducing water consumption. The atomizing nozzles adopt a detachable connection structure, which is convenient for cleaning or replacement, effectively preventing nozzle blockage caused by water quality problems, ensuring long-term stable spray performance, and reducing the maintenance burden.

[0025] (5) The support structure of this utility model adopts a combination of mounting plates and angle irons. The mounting plates and side beams are detachably connected, and the angle irons are horizontally connected to the two mounting plates to form a stable support system. This design not only ensures effective load-bearing capacity for the upper heating pipes and the lower spray device, but also realizes modular assembly, which facilitates on-site installation and subsequent local maintenance, and improves the overall adaptability and maintenance convenience of the device.

They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] Example 1:

[0033] Combined with appendix Figures 1-2 A composite device combining spray humidification and heating pipe arrays for an air cooler includes side beams 1, heating pipe arrays 2, and a spray device 3. Two side beams 1 serve as the structural support and mounting carrier for the entire device, fixedly installed on the left and right sides of the air inlet of the air cooler, forming the main frame of the device. Heating pipe arrays 2 are installed in the upper region between the two side beams 1 to heat the air entering the air cooler; the spray device 3 is installed in the lower region between the two side beams 1 to spray water mist into the incoming air for evaporative cooling.

[0034] This embodiment can automatically or manually switch operating modes according to changes in ambient temperature: When the ambient temperature is high, the heating tube array 2 is turned off, and the spray device 3 is activated. The spray device 3 sprays fine water mist into the air inlet channel. The water mist evaporates rapidly in the air and absorbs the sensible heat of the air, thereby effectively reducing the dry-bulb temperature of the air entering the air cooler, improving the heat exchange efficiency of the air cooler, and avoiding insufficient cooling of the process medium due to high temperature. When the ambient temperature is low, the spray device 3 is turned off, and the heating tube array 2 is turned on to preheat the air entering the air cooler, preventing the process medium from freezing or increasing in viscosity in the tube bundle under low-temperature conditions, and ensuring stable operation of the air cooler in winter or cold conditions. Through the synergistic cooperation of the above two functions, this composite device can adapt to different seasons throughout the year and operating environments with large day-night temperature differences, ensuring continuous and reliable operation of the air cooler, maintaining the stability of the process medium outlet temperature, and improving the overall system's energy efficiency ratio and operational safety.

[0035] Multiple support members 4 are also provided between the two side beams 1. These support members 4 are distributed vertically and are used to provide structural support or positional fixation for the heating pipe row 2 and the spray device 3, respectively. The installation of support members 4 not only enhances the overall rigidity and structural stability of the device, but also facilitates the installation, disassembly and maintenance of the heating pipe row 2 and the spray device 3, thereby improving the operability and long-term operational reliability of the equipment.

[0036] Example 2:

[0037] Combined with appendix Figures 1-2 A composite device combining spray humidification and heating tube array for air coolers is proposed. Based on Embodiment 1, the specific structural form of the heating tube array 2 is optimized. The heating tube array 2 can adopt an electric heating tube structure, that is, it is composed of several electric heating elements, which directly convert electrical energy into heat energy after being energized to heat the flowing air. This solution does not require an external heat source, has fast control response, and flexible start and stop, making it suitable for occasions with stable power supply and high requirements for heating accuracy.

[0038] Alternatively, the heating tube array 2 can also employ a structure of multiple interconnected medium flow pipes. Hot water, low-pressure steam, or other waste heat media from processes can be circulated within these pipes, indirectly heating the air using an external heat source. This structure effectively utilizes existing thermal energy resources in the factory, reducing operating energy consumption and is suitable for industrial scenarios with a stable supply of heat media. Furthermore, the medium flow pipes are inclined, with the inclination direction aligned with the medium flow direction. This allows residual liquid media inside the pipes to be smoothly drained under gravity during shutdown or maintenance, avoiding the risk of freezing or corrosion due to water accumulation. It also facilitates rapid establishment of thermal circulation during system startup, improving heating response speed and operational safety.

[0039] Example 3:

[0040] Combined with appendix Figures 1-2 A composite device combining spray humidification and heating pipes for air coolers is disclosed, which refines the structure of the spray device 3 based on Embodiment 1 or Embodiment 2. The spray device 3 includes connecting pipes 3-1 and atomizing nozzles 3-2. Multiple connecting pipes 3-1 are arranged horizontally between two side beams 1, and are connected in series or parallel via pipelines to form a complete water supply network, ensuring uniform water distribution. Multiple atomizing nozzles 3-2 are spaced along the length of each connecting pipe 3-1, and each atomizing nozzle 3-2 is connected to the internal flow channel of the corresponding connecting pipe 3-1, converting water pressure into fine water mist particles to achieve uniform coverage of the air inlet section. This layout effectively avoids localized over-humidification or spray blind spots, improves evaporative cooling efficiency, and reduces water consumption. In addition, the atomizing nozzle 3-2 and the connecting pipe 3-1 are connected in a detachable manner, such as by threaded connection or quick-connect fitting, which facilitates regular cleaning, replacement or maintenance, prevents nozzle blockage caused by water impurities, ensures long-term stable spray performance, and reduces maintenance costs.

[0041] Example 4:

[0042] Combined with appendix Figures 1-2 A composite device combining spray humidification and heating pipe arrays for air coolers is disclosed, based on any of the aforementioned embodiments, with a clearer description of the specific structure of the support component 4. The support component 4 includes mounting plates 4-1 and angle irons 4-2. Two mounting plates 4-1 are provided, each detachably connected to two side beams 1 via bolts or other fasteners, facilitating on-site assembly and subsequent maintenance of the entire device. An angle iron 4-2 is positioned between the two mounting plates 4-1, with both ends of the angle iron 4-2 securely connected to the corresponding mounting plates 4-1 via welding, bolts, or riveting, forming a stable lateral support structure. This structure effectively supports the weight of the heating pipe array 2 and the spray device 3. Furthermore, the modular and detachable connection method allows for the replacement or adjustment of local components without dismantling the entire device, improving the maintainability and adaptability of the equipment.

[0043] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
