[0035] Compared with the prior art, the natural air cooler provided by the utility model, smoke enters the smoke inlet box 101 and flows upwards along the air cooling mechanism 201 into the flow guide box 301, and then flows downwards along the air cooling mechanism 201 into the other group of the air cooling mechanism 201 in the same flow guide box 301 and flows upwards through the other group of the air cooling mechanism 201 in the same conversion box 102 until the smoke flows out of the smoke outlet box 103, and the cooling is completed. The air cooling mechanism 201 forms an air flow channel in the up-down direction, and does not need to be provided with a corner, thereby reducing the probability of smoke blockage. The supporting frame 4 provides a stable foundation for the whole system, ensures the stability and safety of each component during operation, and reduces the risk of equipment damage caused by vibration or external force. The air cooling assembly 2 comprises a plurality of air cooling mechanisms 201, thereby prolonging the cooling path of the smoke and further enhancing the cooling effect. The flow direction of the smoke is changed through the conversion assembly 1 and the guide assembly 3, thereby avoiding the problem of smoke blockage in the pipeline. The natural cooling of the smoke is realized through the plurality of air cooling mechanisms 201, the air cooling mechanism 201 is arranged in the up-down direction, does not need to be provided with a corner, not only avoids the problem that the serpentine pipeline is easy to be blocked, but also reduces the occupied space, is suitable for various places, and has a wide application range.

[0036] Specifically, the smoke inlet box 101 is provided with a smoke inlet, the smoke outlet box 103 is provided with a smoke outlet, the smoke inlet is provided with a smoke inlet pipe, and the smoke outlet is provided with a smoke outlet pipe.

[0037] In some embodiments, referring to Figures 1 to 2 The natural air cooler further comprises a water seal assembly 5 arranged below the conversion assembly 1, the water seal assembly 5 comprises a water tank 501 and a plurality of water seal pipes 502, the water tank 501 is arranged below the conversion assembly 1, and the water tank 501 stores cooling water; the smoke inlet box 101 and the smoke outlet box 103 are respectively provided with the water seal pipe 502, and each conversion box 102 is respectively provided with the water seal pipe 502, and the bottom ends of the plurality of water seal pipes 502 are arranged in the water tank 501 and are below the liquid level of the cooling water.

[0038] The flue gas contains a certain amount of dust. Since the bottom end of the water seal pipe 502 is inserted below the liquid level of the water tank 501, the bottom of the water seal pipe 502 is water sealed, which can avoid flue gas leakage on the one hand, and can float the residual dust in the water seal pipe 502 on the liquid surface for subsequent ash cleaning in the water seal groove. In addition, the cooling water in the water tank 501 can also cool the flue gas in the water seal pipe 502. Since the flue gas is flowing, it cooperates with the air cooling mechanism 201 to cool and cool the flue gas, thereby improving the cooling efficiency. The introduction of the water seal assembly 5 not only significantly improves the heat dissipation performance of the natural air cooler, but also enhances the stability and reliability of the system, while simplifying the maintenance operation, and has high practicality and economy.

[0039] In some embodiments, referring to Figure 1 , the conversion box 102 includes a conversion body 1021 and a maintenance door 1022. The conversion body 1021 is provided with an inspection hole; the maintenance door 1022 is rotationally connected to the conversion body 1021 and closes the inspection hole.

[0040] After long-term use, the dust in the flue gas is easy to adhere to the inner wall of the conversion box 102, thereby causing the use space of the conversion box 102 to be compressed. Therefore, the inspection hole is provided on the conversion body 1021, and the maintenance door 1022 is opened to regularly clean the accumulated dust in the conversion body 1021, thereby ensuring the normal operation of the entire device.

[0041] In some embodiments, referring to Figure 1 and Figure 3 , the air cooling mechanism 201 includes a plurality of groups of air cooling modules distributed along a first path. The first path is parallel to the distribution path of the conversion box 102. The air cooling module includes a plurality of air cooling pipes 2011 distributed along a second path. The second path is perpendicular to the first path.

[0042] The plurality of groups of air cooling modules distributed along the first path can effectively cover the distribution path of the conversion box 102, ensuring uniform and comprehensive cooling effect. The plurality of air cooling pipes 2011 in each group of air cooling modules are distributed along the second path, and the second path is perpendicular to the first path. This perpendicular and cross layout enhances the uniformity and efficiency of cooling, and avoids the occurrence of local overheating. This embodiment not only improves the overall performance of the cooling system, but also simplifies the installation and maintenance process, and reduces the operating cost. By optimizing the distribution and layout of the air cooling module, the cooling effect and the reliability of the system are significantly improved.

[0043] In some embodiments, referring to Figure 1The flow guide box 301 includes a flow guide body 3011 and an observation cover 3012. The flow guide body 3011 is provided with an observation opening at the top, and the air cooling mechanism 201 is inserted into the flow guide body 3011. The observation cover 3012 is rotatably or detachably connected to the flow guide body 3011. The observation cover 3012 has a closed state of covering the observation opening and an open state of opening the observation opening.

[0044] The observation cover 3012 is rotatably or detachably connected, which can quickly open the observation opening when needed, facilitating inspection and maintenance, and can also close the observation opening during normal operation, ensuring the sealing and stability of the system. This flexible design not only enhances the practicality of the equipment, but also reduces downtime caused by maintenance and improves overall operation efficiency. The observation opening at the top of the flow guide body 3011 facilitates viewing the internal conditions of the flow guide body 3011 and facilitates real-time monitoring and maintenance of the flow guide body 3011, improving the operability and maintenance efficiency of the system.

[0045] Optionally, the observation cover 3012 is provided with a handle.

[0046] Optionally, the observation cover 3012 is clamped or screwed to the flow guide body 3011.

[0047] In some embodiments, referring to Figure 1 The flow guide body 3011 is provided with a plurality of observation openings, and each observation opening corresponds to an air cooling mechanism 201. Each observation opening is provided with a corresponding observation cover 3012.

[0048] By providing a plurality of observation openings and each observation opening corresponding to an air cooling mechanism 201, independent monitoring and maintenance of each air cooling module can be achieved, avoiding the situation that local faults affect the overall system operation. Each observation opening is provided with a corresponding observation cover 3012, which is rotatably or detachably connected. It can be individually opened for inspection or maintenance when needed, and can remain closed during normal operation to ensure the sealing and stability of the system. This embodiment not only improves the flexibility and efficiency of maintenance, but also reduces unnecessary downtime and operating costs. In addition, the distribution design of multiple observation openings makes the operation status of the cooling mechanism more transparent, facilitating timely discovery and solution of problems, thereby improving the reliability and service life of the system.

[0049] In some embodiments, referring to Figure 1 The smoke inlet box 101 and the smoke exhaust box 103 are both provided with cleaning holes, and the cleaning holes are covered with cleaning covers 1011. The cleaning covers 1011 are rotatably or detachably connected to the smoke inlet box 101 or the smoke exhaust box 103.

[0050] Cleaning holes are formed on the smoke inlet box 101 and the smoke exhaust box 103, and are covered with cleaning covers 1011 connected in a rotating or detachable manner, which can facilitate regular cleaning and maintenance of the interior of the box, effectively prevent the accumulation of dust or debris, and thus ensure the long-term stable operation of the system. The design of the cleaning cover 1011 can quickly open when needed, facilitating cleaning and inspection, and can remain closed during normal operation, ensuring the sealing and safety of the system. This embodiment not only improves the maintainability of the equipment, but also reduces the downtime caused by cleaning and maintenance, and improves the overall operation efficiency.

[0051] In some embodiments, referring to Figure 1 , the guide box 301 includes a plurality of guide plates connected in sequence and forming a frame structure, the frame structure has a gap, and further includes a top plate covering the top of the frame structure and a bottom plate covering the bottom of the frame structure, a plurality of guide boxes 301 are connected in sequence, and the guide plates shield the gaps of adjacent frame structures to form a closed space in the guide box 301.

[0052] The gap design of the frame structure and the shielding of the gaps of adjacent frame structures by the guide plates enable the plurality of guide boxes 301 to be connected in sequence and closely, which simplifies the installation process and ensures the sealing and stability of the connection, reducing the risk of energy loss or medium leakage. In addition, since there is a gap in each frame, compared with setting each frame structure as a closed structure connected at the beginning and end, the material and weight are reduced, and the cost is reduced.

[0053] In some embodiments, referring to Figure 1 , the upper part and the lower part of the air-cooled pipe 2011 are respectively provided with a sealing ring, the sealing ring of the upper part is used to seal the gap between the air-cooled pipe 2011 and the guide box 301, and the sealing ring of the lower part is used to seal the gap between the air-cooled pipe 2011 and the conversion box 102, the smoke inlet box 101 or the smoke exhaust box 103.

[0054] The upper sealing ring effectively seals the gap between the air-cooled pipe 2011 and the guide box 301, preventing smoke leakage and ensuring the stability and efficiency of the cooling process. The lower sealing ring is used to seal the gap between the air-cooled pipe 2011 and the conversion box 102, the smoke inlet box 101 or the smoke exhaust box 103, further enhancing the overall sealing of the system and avoiding energy loss or medium leakage problems caused by the gap. This double sealing design not only improves the reliability of the system, but also reduces the maintenance requirements and reduces the operating cost. In addition, the use of the sealing ring simplifies the installation process and ensures that the connection between the air-cooled pipe 2011 and each box is more close and stable, thereby optimizing the overall performance of the system.

[0055] In some embodiments, referring to Figure 1 , the longitudinal section of the conversion box 102 is trapezoidal, and the width of the trapezoid gradually decreases from top to bottom.

[0056] After the flue gas enters the conversion box 102, due to the longitudinal section of the conversion box 102 is a trapezoid gradually decreasing from top to bottom, so the flue gas hits on the side wall of the conversion box 102, and the flue gas enters the adjacent air cooling mechanism 201 under the reaction force, in this process, the flue gas flow rate is reduced, thereby facilitating the flue gas cooling. In addition, the structure of the conversion box 102 in the embodiment is also beneficial to deposit the dust in the flue gas on the inner wall of the conversion box 102, and is also beneficial to realize the flow guiding of the flue gas.

[0057] The above merely describes the preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
