Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, and in particular to an air compressor with heat recovery function. Background Technology

[0002] During operation, air compressors inevitably generate a large amount of heat as their internal mechanical components, such as pistons and cylinders, rotate at high speeds. To effectively utilize this potentially wasted heat energy, modern air compressor designs often integrate heat recovery functions. This function uses advanced heat exchange technology to collect the heat generated by the air compressor and convert it into heat energy that can be used for other industrial processes or heating domestic water, thereby achieving efficient energy utilization and energy conservation and emission reduction goals.

[0003] An air compressor with waste heat recovery function, disclosed in announcement number CN217176822U, belongs to the field of air compressor technology. Its key technical features include an air compressor body, a storage mechanism on the right side of the air compressor body, and threaded sealing covers on the top and rear of the storage mechanism. The top and right side of the storage mechanism are respectively connected to a first exhaust pipe and a second exhaust pipe. The storage mechanism includes a first storage box, a second storage box, and a partition. The top of the second storage box is fixedly connected to the bottom of the partition, and the top of the partition is fixedly connected to the bottom of the first storage box. Two sealing covers are threadedly connected to the top of the first storage box and the rear of the second storage box, respectively. This invention solves the problem that existing air compressors lack the function of recovering waste heat, resulting in the waste of some heat energy and inefficient energy utilization. This renders the air compressor, which should be energy-saving and environmentally friendly, wasteful of resources and inconvenient for users.

[0004] When the above-mentioned equipment is in use, the gas containing heat energy released by the air compressor is introduced into the storage mechanism, where the water inside the mechanism recovers the heat energy. However, during the recovery process, some gas containing heat energy will be discharged directly from the exhaust port without sufficient time to come into contact with the water, resulting in waste. Utility Model Content

[0005] The purpose of this invention is to provide an air compressor with heat recovery function to solve the problem in the prior art where the short contact time of hot steam during heat exchange leads to the waste of some heat.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An air compressor with heat recovery function includes an air compressor body. A first recovery mechanism and a second recovery mechanism are arranged on one side of the air compressor body. The first recovery mechanism is located above the second recovery mechanism, with one side of the first recovery mechanism inclined downwards and the same side of the second recovery mechanism inclined upwards. The first recovery mechanism includes a recovery box, a detour air pipe, and a heat-conducting spiral plate. The detour air pipe is located inside the recovery box, with one end being an air inlet and the other end being an air outlet. The heat-conducting spiral plate spirally surrounds the pipe. The second recovery mechanism includes an insulated box, a liquid guide pipe, a gas guide pipe, a heat-conducting strip, a partition heat-conducting strip, and a baffle. The liquid guide pipe is installed inside the insulated box, and the gas guide pipe is located inside the liquid guide pipe. The heat-conducting strip and the partition heat-conducting strip are both inserted into the periphery of the gas guide pipe, and one end of the partition heat-conducting strip is fixedly connected to the inner wall of the liquid guide pipe. The baffle is located between the two partition heat-conducting strips and is fixedly connected to the partition heat-conducting strips. The two partition heat-conducting strips, a single baffle, and the gas guide pipe form a condensation storage area.

[0008] Preferably, the air inlet is connected to the air outlet of the air compressor body via a hose, one end of the air guide pipe is the accumulation end and the other end is the exhaust end, a connecting pipe is connected to the outside of the air outlet, the other end of the connecting pipe is connected to the accumulation end, and the connecting pipe passes through the recovery box and the heat insulation box.

[0009] Preferably, the diameter of the air inlet port is larger than the diameter of the air outlet port.

[0010] Preferably, both ends of the gas guide pipe are penetrated by liquid guide pipes. Drain pipe 2 and drain pipe 3 are provided below the end of the liquid guide pipe near the exhaust end. Drain pipe 3 is connected to the interior of the liquid guide pipe, and drain pipe 2 is connected to the condensation storage area. Drain pipe 1 is provided on the side of the recovery box near the heat insulation box.

[0011] Preferably, the bottom of the air guide pipe has uniformly distributed through holes, which are connected to the condensation storage area.

[0012] Preferably, the space between the liquid guide tube and the gas guide tube is filled with liquid, and the inside of the recovery tank is filled with liquid.

[0013] Preferably, the direction of the heat-conducting insert is consistent with that of the air duct.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] I. This utility model, through the cooperation of the first and second recovery mechanisms, extends the flow path of the hot air released by the air compressor body within the meandering air pipe, thereby increasing the heat exchange opportunities. At the same time, the surrounding arrangement of the heat-conducting spiral plates further enhances the heat exchange process, ensuring that more hot air can fully contact the liquid, thus significantly improving the heat recovery efficiency and avoiding heat energy waste.

[0016] Second, by setting the first and second recycling mechanisms in different directions, the condensed water droplets can flow smoothly into the air guide pipe. The through hole at the bottom of the air guide pipe, together with the heat-conducting strip of the partition and the baffle, form a condensation storage zone, which ensures that the condensed water droplets can be captured and avoids the waste of water droplets. In addition, the collected water droplets can absorb the heat of the remaining hot air in the air guide pipe through the heat-conducting strip of the partition in the condensation storage zone, realizing the secondary recovery of heat.

[0028] Reference Figures 1-6 As shown, this utility model provides an air compressor with heat recovery function, including an air compressor body 1. A recovery mechanism 1 2 and a recovery mechanism 2 3 are provided on one side of the air compressor body 1. The recovery mechanism 1 2 is located above the recovery mechanism 2 3. One side of the recovery mechanism 1 2 is inclined downward, and the same side of the recovery mechanism 2 3 is inclined upward.

[0029] The recycling mechanism 2 includes a recycling box 21, a detour air pipe 23, and a heat-conducting spiral plate 24. The detour air pipe 23 is located inside the recycling box 21. One end of the detour air pipe 23 is the air inlet 25, and the other end is the air outlet 26. The heat-conducting spiral plate 24 is spirally inserted around the periphery of the detour air pipe 23.

[0030] The second recycling mechanism 3 includes an insulated box 31, a liquid guide pipe 32, a gas guide pipe 33, a heat-conducting insert 36, a partition heat-conducting strip 37, and a baffle 38. The liquid guide pipe 32 is installed inside the insulated box 31, and the gas guide pipe 33 is located inside the liquid guide pipe 32. The heat-conducting insert 36 and the partition heat-conducting strip 37 are both inserted into the periphery of the gas guide pipe 33, and one end of the partition heat-conducting strip 37 is fixedly connected to the inner wall of the liquid guide pipe 32. The baffle 38 is located between the two partition heat-conducting strips 37 and is fixedly connected to the partition heat-conducting strips 37. The two partition heat-conducting strips 37, the single baffle 38, and the gas guide pipe 33 form a condensation storage area.

[0031] The air compressor body 1 is an air compressor, and the recovery mechanism 1 2 and the recovery mechanism 2 3 are heat energy recovery devices for the air compressor body 1.

[0032] The recovery mechanism 12 is tilted downward at 10 degrees on the side near the air outlet 26, while the recovery mechanism 23 is tilted upward at 10 degrees on the same side, so that the condensed water can flow to the drain pipe 239. A support column is provided at the angle between the recovery mechanism 12 and the recovery mechanism 23.

[0033] In a further embodiment, the air inlet 25 is connected to the air outlet of the air compressor body 1 via a hose. One end of the air guide pipe 33 is the stacking end 34, and the other end is the exhaust end 35. The air outlet 26 is connected to a connecting pipe 27, and the other end of the connecting pipe 27 is connected to the stacking end 34. The connecting pipe 27 passes through the recovery box 21 and the heat insulation box 31.

[0034] In this embodiment, a seal is provided at the point where the connecting pipe 27 passes through the recovery box 21 and the heat insulation box 31; the meandering air pipe 23, the liquid guide pipe 32 and the air guide pipe 33 all run in a left-right reciprocating direction to increase the travel distance of the hot air flow, thereby extending the duration of the flow.

[0035] In a further embodiment, the port diameter of the air inlet 25 is larger than the port diameter of the air outlet 26.

[0036] In this embodiment, the heat-conducting spiral plate 24 is a spiral disc, part of which is inserted into the inside of the detour air pipe 23, and the other part is located inside the recovery box 21. It can be used to guide the hot steam and condensed water droplets in the recovery box 21, and can also conduct heat to increase the surface area of ​​the detour air pipe 23. The inner diameter of the heat-conducting spiral plate 24 is the same as the diameter of the air outlet 26. With the air inlet 25 having a larger diameter than the air outlet 26, the condensed water droplets can be prevented from being blocked by the detour air pipe 23.

[0037] In a further embodiment, both ends of the gas guide pipe 33 pass through the liquid guide pipe 32. A second drain pipe 39 and a third drain pipe 391 are provided below the end of the liquid guide pipe 32 near the exhaust end 35. The third drain pipe 391 is connected to the interior of the liquid guide pipe 32, and the second drain pipe 39 is connected to the condensation storage area. A first drain pipe 22 is provided on the side of the recovery box 21 near the heat insulation box 31.

[0038] In this embodiment, the condensation storage area is used to collect condensed water, and the drain pipe 391 passes through the heat insulation box 31 to release the liquid after absorbing heat energy. Similarly, the drain pipe 22 is used to release the liquid in the recovery box 21. The drain pipe 22, the drain pipe 39, and the drain pipe 391 all have valves.

[0039] In a further embodiment, the bottom of the air duct 33 is provided with uniformly distributed through holes 331, which connect to the condensation storage zone.

[0040] In this embodiment, the through hole 331 is used to facilitate the passage of condensed water droplets to the condensation storage area.

[0041] In a further embodiment, liquid is filled between the liquid guide tube 32 and the gas guide tube 33, and liquid is filled inside the recovery tank 21.

[0042] In this embodiment, the injected liquid is used to absorb heat energy so that it can be utilized.

[0043] In a further embodiment, the orientation of the heat-conducting insert 36 is consistent with that of the air duct 33.

[0044] In this embodiment, the meandering air pipe 23, the heat-conducting spiral plate 24, the air pipe 33, the heat-conducting insert 36, the partition heat-conducting strip 37, and the baffle 38 are all made of metal with good thermal conductivity, and the inner walls of the recovery box 21 and the heat insulation box 31 are provided with a heat insulation layer.

[0045] The working principle of this utility model is as follows:

[0046] When the hot air generated during the operation of the air compressor body 1 enters the interior of the detour air pipe 23 through the hose, it is guided by the heat-conducting spiral plate 24 and enters the interior of the guide pipe 33 through the outlet end 26 and the connecting pipe 27 of the detour air pipe 23. During this process, since the diameter of the inlet end 25 of the detour air pipe 23 is larger than that of the outlet end 26, it will be gradually blocked during the flow of hot air. Combined with the guidance of the heat-conducting spiral plate 24, the time for hot air to flow through the interior of the detour air pipe 23 is extended. Thus, the liquid inside the recovery box 21 has more time to absorb the heat from the hot air through the detour air pipe 23 and the heat-conducting spiral plate 24, thereby improving the recovery efficiency and avoiding heat waste. In addition, the hot air entering the interior of the guide pipe 33 will transfer heat to the liquid between the liquid pipe 32 and the guide pipe 33 through the guide pipe 33 itself and the heat-conducting insert 36 inserted around the exterior of the guide pipe 33, thereby performing secondary heat recovery and further improving the heat recovery efficiency.

[0047] When hot air flows inside the meandering air pipe 23 and the air guide pipe 33, it comes into contact with the cooler heat-conducting spiral plate 24 and heat-conducting insert 36, condensing into water droplets. Because the recovery mechanism 1 2 is tilted downward at 10 degrees on the side near the air outlet 26, and the recovery mechanism 2 3 is tilted upward at 10 degrees on the same side, the water droplets condensed inside the meandering air pipe 23 will flow into the air guide pipe 33. Then, the partition heat-conducting strips 37 and baffles 38 inserted on both sides of the bottom of the air guide pipe 33, as well as the through holes 331 opened at the bottom of the air guide pipe 33, can collect the water droplets. The water droplets can also absorb the heat of the hot air passing through the air guide pipe 33 through the partition heat-conducting strips 37. This not only improves the heat recovery efficiency again, but also avoids wasting the condensed water droplets, thus further avoiding waste.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
