Technical Field
[0001] This utility model relates to the field of air compressor technology, specifically to an air compressor waste heat recovery and reuse device. Background Technology
[0002] An air compressor is a device used to compress gas. During operation, the air compressor generates hot steam. After being processed by a waste heat recovery and reuse device, this steam can be effectively utilized in other equipment or processes, achieving energy savings.
[0003] Existing waste heat recovery and reuse devices for air compressors have complex structures and unreasonable designs. During heat exchange, hot steam passes through heat exchange pipes placed in water to be exchanged, allowing the water to absorb heat to achieve the heat exchange effect. However, existing devices typically ignore the characteristic that heat rises to the surface, resulting in significant temperature differences at different depths within the heat exchange chamber. This makes it difficult to maintain a uniform water temperature at different depths, leading to poor usability of the final water. Therefore, the inventors have improved the structure of the waste heat recovery and reuse device for air compressors. Utility Model Content

It is suitable for the waste heat recovery of hot steam released by different air compressors, and the final water has high usability. It solves the problems mentioned in the above technical background.

[0006] Preferably, the hot steam inlet pipe is L-shaped and located at the bottom of the heat exchange box, and the outlet pipe is located at the top of the heat exchange box. The hot steam inlet pipe is used to connect to the pipe that outputs hot steam on the air compressor, and the outlet pipe discharges the recovered steam and other substances upwards.
[0007] Preferably, protective sleeves are fixed on both the hot steam inlet pipe and the outlet pipe. The two protective sleeves are fixed to the top and bottom of the heat exchange box, respectively, and are used to protect the outside of the hot steam inlet pipe or the outlet pipe.
[0008] Preferably, the pitch of the lower spiral tube is between 15.5cm and 19cm, and the pitch of the upper spiral tube is between 12.5cm and 15cm.
[0009] Preferably, an inner flow channel is provided at both ends of the fixed plate.

[0011] Preferably, the tilting motor is horizontally positioned and fixed to the outside of the heat exchange box, so that the heat exchange box can support the tilting motor.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model provides a waste heat recovery and reuse device for air compressors. The device includes a supporting mechanism and a heat exchange mechanism and an adjustment mechanism mounted on the supporting mechanism. The overall structure is simple and rationally designed. The heat exchange mechanism includes a fixed plate and a spiral pipe mounted on the fixed plate. The spiral pipe includes a lower spiral pipe and an upper spiral pipe connected above the lower spiral pipe. The ends of the lower and upper spiral pipes that are far apart from each other are fixedly connected to the fixed plate, and the pitch of the lower spiral pipe is greater than that of the upper spiral pipe. Flexible hoses are provided at both ends of the spiral pipe, and the two hoses are respectively connected to the top and bottom of the fixed plate. A spiral pipe is used to transport waste heat, and during the transport of hot steam, the heat is dissipated to the cold water in the heat exchange box. The waste heat is used to heat the cold water. Because the spiral pipe transports hot steam from bottom to top, and the pitch of the lower spiral pipe is greater than that of the upper spiral pipe, the water at the bottom of the heat exchange box absorbs more heat, the water in the center absorbs a moderate amount of heat, and the water at the top absorbs less heat. In addition, the characteristic that heat rises continuously can effectively balance the water temperature at different depths in the heat exchange box, making the water temperature at different depths relatively uniform and avoiding the problem of excessive temperature differences at different depths. It is highly practical.
[0014] 2. The adjustment mechanism in this utility model includes a tilting motor, the output end of which is connected to a support shaft. The support shaft is fixedly connected to a fixed plate and is located inside the heat exchanger chamber. The operation of the tilting motor can drive the spiral pipe to tilt at a certain angle. Therefore, during use, the angle of the spiral pipe can be adjusted according to the different temperatures of the hot steam released by different air compressors, so that the spiral pipe is tilted at a certain angle. This can change the efficiency of the spiral pipe in influencing the temperature at different depths inside the heat exchanger chamber. When the hot steam temperature is high, the tilt angle is increased to change the temperature difference at different depths inside the heat exchanger chamber in a short time, which is conducive to better maintaining the temperature balance at different depths. Therefore, this device can well adapt to the waste heat recovery of hot steam released by different air compressors, resulting in high usability of the final water, and is suitable for widespread use.

[0024] Please see Figure 1 The present invention provides an embodiment of an air compressor waste heat recovery and reuse device, comprising a support mechanism 1, the support mechanism 1 comprising a heat exchange box 11, a water inlet pipe 15 fixed to the top of the heat exchange box 11, and a cap provided on the water inlet pipe 15 for sealing the water inlet pipe 15. Water or other liquids for heat recovery can be added into the heat exchange box 11 through the water inlet pipe 15. A drain pipe 16 is connected to the bottom of the heat exchange box 11, and a valve is provided on the drain pipe 16. The structure of the valve is prior art, and its structure will not be described in detail here.
[0025] Please see Figure 2 The heat exchange box 11 is a hollow cavity structure, and a hot steam input pipe 12 and an output pipe 13 are connected to the heat exchange box 11. The hot steam input pipe 12 is L-shaped and located at the bottom of the heat exchange box 11, while the output pipe 13 is located at the top of the heat exchange box 11. The hot steam input pipe 12 is used to connect to the pipe that outputs hot steam from the air compressor, and the output pipe 13 discharges the recovered steam and other generated substances upwards. A heat exchange mechanism 2 is provided on the supporting mechanism 1. The heat exchange mechanism 2 includes a fixed plate 21 and a spiral pipe 22 disposed on the fixed plate 21. Both the fixed plate 21 and the spiral pipe 22 are suspended in the cavity of the heat exchange box 11. The spiral pipe 22 includes a lower spiral pipe 221 and an upper spiral pipe 222 connected above the lower spiral pipe 221. The lower spiral pipe 221 and the upper spiral pipe 222 are connected to each other. The ends of the pipes 222 that are far apart from each other are fixedly connected to the fixed plate 21. The pitch of the lower spiral pipe 221 is greater than that of the upper spiral pipe 222. The pitch of the lower spiral pipe 221 is between 15.5cm and 19cm, and the pitch of the upper spiral pipe 222 is between 12.5cm and 15cm. The spiral pipes 22 transport hot steam from bottom to top. Since the pitch of the lower spiral pipe 221 is greater than that of the upper spiral pipe 222, the water at the bottom of the heat exchange box 11 absorbs more heat, the water in the center absorbs a moderate amount of heat, and the water at the top absorbs less heat. In addition, the characteristic that heat itself will rise continuously can effectively balance the water temperature at different depths in the heat exchange box 11, making the water temperature at different depths relatively uniform and avoiding the problem of excessive water temperature differences at different depths.
[0026] Please see Figure 3Protective sleeves 14 are fixed on both the hot steam inlet pipe 12 and the outlet pipe 13. The two protective sleeves 14 are fixed to the top and bottom of the heat exchange box 11, respectively. The two protective sleeves 14 are used to protect the outside of the hot steam inlet pipe 12 or the outlet pipe 13. Flexible hoses 23 are provided at both ends of the spiral pipe 22. The two flexible hoses 23 are connected to the top and bottom of the fixing plate 21, respectively. Inner flow channels 211 are provided at both ends of the fixing plate 21. The two inner flow channels 211 are located inside the fixing plate 21. The openings on the opposite sides of the two inner flow channels 211 are connected to the two flexible hoses 23, and the openings on the opposite sides of the two inner flow channels 211 are connected to the lower spiral pipe 221 and the upper spiral pipe 222, respectively.
[0027] Please see Figure 4 An adjustment mechanism 3 is provided on one side of the heat exchange mechanism 2. The adjustment mechanism 3 includes a tilting motor 31, which is horizontally positioned and fixed to the outside of the heat exchange box 11. Therefore, the heat exchange box 11 can support the tilting motor 31.
[0028] Please see Figure 5 The output end of the flip motor 31 is connected to a support shaft 32, which is fixedly connected to the fixed plate 21. The support shaft 32 is located inside the heat exchange box 11. When the flip motor 31 is running, it can drive the support shaft 32, the fixed plate 21, and the spiral pipe 22 to flip. The angle range of the fixed plate 21 and the spiral pipe 22 to flip is between 0° and 45°. When the flip motor 31 is running, it drives the spiral pipe 22 to flip at a certain angle. Therefore, during use, the angle of the spiral pipe 22 can be adjusted according to the different temperatures of the hot steam released by different air compressors, so that the spiral pipe 22 is tilted at a certain angle. This can change the efficiency of the spiral pipe 22 in affecting the temperature at different depths inside the heat exchange box 11. When the hot steam temperature is high, the tilt angle is increased to change the temperature difference at different depths inside the heat exchange box 11 in a short time. This is conducive to better maintaining the temperature balance at different depths. Therefore, it can well adapt to the waste heat recovery of hot steam released by different air compressors, and the final water has high usability.
[0029] Working principle: Please refer to the following again. Figures 1 to 5 In the operation of this utility model, sufficient water is added to the heat exchange box 11 through the water inlet pipe 15, and the hot steam inlet pipe 12 is connected to the pipe or other facilities that discharge hot steam from the air compressor. The hot steam enters the lower spiral pipe 221 after passing through the hot steam inlet pipe 12, the hose 23 and the inner flow channel 211, and then floats to the upper spiral pipe 222. The heat of the lower spiral pipe 221 and the upper spiral pipe 222 is released to the water in the heat exchange box 11 cavity, completing the heat exchange and realizing the recovery and utilization of waste heat. Finally, the remaining steam and other substances are released through the outlet pipe 13. By opening the valve, the water that has absorbed waste heat can be released from the drain pipe 16.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
