Description

Technical Field

[0001] The present invention relates to the technical field of waste heat recovery, and specifically to an air compressor waste heat recovery and reuse system. Background Art

[0002] During the operation of an air compressor, a large amount of heat is generated. Using a waste heat recovery system can recover the waste heat to replace some traditional energy sources (such as coal, natural gas, electricity, etc.) to meet the enterprise's hot water, heating or drying needs. At the same time, the waste heat recovery system can operate integrally with the air compressor, making full use of the waste heat generated by the air compressor, which is equivalent to improving the energy utilization efficiency of the air compressor and enhancing the comprehensive utilization rate of the equipment.

[0003] For example, a Chinese patent (publication number: CN117628965B) discloses an air compressor waste heat recovery device, including a water tank and a hot air box; the hot air box is fixedly connected to the top end of the water tank; a water inlet pipe and a water outlet pipe are provided on the side wall of the water tank; a circulating water pump is fixedly connected to the side wall of the water tank, and the circulating water pump is interconnected with the water tank through a hose; a first fixing plate is provided at the bottom end of the water tank; an oil inlet pipe is provided at the bottom end of the first fixing plate; a hydraulic cylinder is fixedly connected to the bottom end of the water tank, and the hydraulic rod of the hydraulic cylinder extends into the water tank, and the top end of the hydraulic rod penetrates through the first fixing plate and is provided with a second fixing plate; a first cavity is opened in the first fixing plate; a second cavity is opened in the second fixing plate; a group of spiral heat conducting columns are provided between the first fixing plate and the second fixing plate, and the spiral heat conducting columns have elastic telescopic force; to solve the problems of low utilization rate of the waste heat of the air compressor caused by wind blowing and inability to adjust the heat of the heating air.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 5In this embodiment, a system for recovering and reusing waste heat from an air compressor comprises a box body 1. A plurality of supporting legs 2 are fixed to the bottom of the box body 1. The supporting legs 2 can significantly improve the stability of the box body 1. A heat recovery mechanism 3 is provided on the inner bottom wall of the box body 1 to recover the heat from the air compressor and heat the water. A heat conduction component 4 is provided in the heat recovery mechanism 3, which runs through the left and right side walls of the box body 1 and allows the air compressor coolant to pass smoothly. A heat insulation board 5 is fixed to the inner side wall of the box body 1 and is located on the right side of the heat recovery mechanism 3. The heat insulation board 5 serves to separate the space. At the same time, the heat insulation board 5 has good insulation performance. Thermal properties can ensure that the cooling component 6 will not affect the heat recovery mechanism 3 when cooling down. The inner bottom wall of the box body 1 and the right side of the insulation board 5 are provided with a cooling component 6 that can effectively cool down the heat-conducting component 4. The top and bottom of the box body 1 and the right side of the insulation board 5 are provided with multiple heat dissipation holes, and the multiple heat dissipation holes are all connected to the inner cavity of the box body 1. The bottom of the box body 1 and below the multiple heat dissipation holes are provided with a cleaning component 7 that can effectively block dust. The front of the box body 1 is hinged with a movable door through a hinge, and the movable door can be directly opened when water needs to be added to the cooling component 6.

[0031] In addition, the heat recovery mechanism 3 includes a water tank 301 fixed to the inner bottom wall of the box body 1. The water tank 301 can provide space for water to absorb heat. At the same time, the water tank 301 is an insulated water tank with good thermal insulation effects. A clearance groove is provided on the inner bottom wall of the box body 1. Since the space in the box body 1 is limited, the provision of the clearance groove can provide a certain space for the drive motor 302 and improve the space utilization rate. The inner bottom wall of the clearance groove is fixed with a drive motor 302. The drive motor 302 can provide stable and continuous power for the stirring component 306. The inner bottom wall of the water tank 301 is fixedly connected to a water inlet pipe 303 that passes through the inner bottom wall of the water tank 301 and the left side wall of the box body 1 in sequence. The inner left side wall of the water tank 301 is fixedly connected to a water outlet pipe 304 that passes through the left side wall of the water tank 301 and the left side wall of the box body 1 in sequence. Generally, the density of hot water is The temperature of the water flowing out of the water outlet pipe 304 is slightly lower than that of cold water, so setting the water outlet pipe 304 to a relatively high position can ensure that the temperature of the water flowing out of the water outlet pipe 304 is relatively high, which is convenient for subsequent use. When taking out hot water from the water outlet pipe 304, it is necessary to pour enough water into the water storage tank 301 through the water inlet pipe 303 in time to ensure that the amount of water in the water storage tank 301 is relatively large to ensure the heat recovery effect. The output shaft of the driving motor 302 is fixed with a transmission rod 305 that passes through the bottom wall of the water storage tank 301. A stirring assembly 306 is provided at the top of the transmission rod 305 and located in the water storage tank 301. The stirring assembly 306 is rotatably connected to the top wall of the water storage tank 301 through a bearing. A transmission assembly 307 that passes through the insulation board 5 is provided on the outer surface of the transmission rod 305 and located below the water storage tank 301. Solenoid valves are provided on both the water inlet pipe 303 and the water outlet pipe 304.

[0032] It should be further noted that the stirring assembly 306 includes a driving rod 3061 fixed to the top of the transmission rod 305. A protective housing 3062 is rotatably connected to the outer surface of the driving rod 3061. The protective housing 3062 can block water, thereby providing a good and stable working environment for other parts inside it. An active gear 3063 is fixed to the outer surface of the driving rod 3061 and inside the protective housing 3062. When the clamping rod 3066 extends into the clamping groove, the active gear 3063 plays a limiting role and successfully locks the driven gear 3069. When the clamping rod 3066 disengages from the clamping groove, the active gear 3063 plays a driving role. Connecting rings 3064 are movably connected to the outer surface of the driving rod 3061 and are respectively located on the upper and lower sides of the active gear 3063. Four spring grooves are formed inside each connecting ring 3064, and a connecting spring 3065 is fixed to the inner wall of each spring groove. When the driving motor 302 is not started, under the action of the connecting spring 3065, both ends of the clamping rod 3066 are respectively located in the clamping groove and the spring groove. The connecting spring 3065 is fixed to one side away from the inner wall of the spring groove and is provided with a clamping rod 3066 extending outside the spring groove. Eight clamping grooves are formed on the outer surface of the driving rod 3061, and the eight clamping grooves respectively face the eight spring grooves. Extension rings 3067 are fixed to the opposite sides of the two connecting rings 3064. The inner side of each extension ring 3067 is rotatably connected to the outer surface of the driving rod 3061 through a bearing. The extension ring 3067 plays a connecting role, and the rotational connection between the connecting ring 3064 and the driving rod 3061 is achieved through the extension ring 3067. Four driven rods 3068 are movably connected between the two connecting rings 3064. Each driven rod 3068 passes through the two connecting rings 3064 and is rotatably connected to the connecting rings 3064 through a bearing. A driven gear 3069 is fixed to the outer surface of each driven rod 3068. When the driven gear 3069 revolves around the active gear 3063, the revolving power is transmitted to the connecting ring 3064 through the driven rod 3068, prompting the connecting ring 3064 to rotate slowly. One side of each driven gear 3069 close to the active gear 3063 meshes with the active gear 3063, and one side of each driven gear 3069 away from the active gear 3063 meshes with the inner side wall of the protective housing 3062.

[0033] It can be understood that sealed bearings are fixed on the outer surfaces of the transmission rod 305 and the driving rod 3061. The sealed bearings have good sealing performance and play a role in waterproofing in this application. At the same time, they ensure good rotational stability of the transmission rod 305 and the driving rod 3061. The transmission rod 305 is rotatably connected to the bottom wall of the water storage tank 301 through a sealed bearing, and the driving rod 3061 is rotatably connected to the protective shell 3062 through a sealed bearing. A plurality of blades are fixed on the outer surface of the protective shell 3062. By rotating the protective shell 3062, the plurality of blades are driven to rotate, promoting the flow of water. Four rib plates are fixed on the outer surface of each extension ring 3067. The rib plates play a role in strengthening the connection and can improve the connection force between the extension ring 3067 and the connection ring 3064. One side of the four rib plates close to the connection ring 3064 is fixed to the connection ring 3064.

[0034] In addition, the heat conduction component 4 includes a liquid inlet pipe 401 fixed to the right side wall of the box body 1. The liquid inlet pipe 401 sequentially penetrates the right side wall of the box body 1 and the right side wall of the water storage tank 301. One end of the liquid inlet pipe 401 far from the right side wall of the box body 1 and located inside the water storage tank 301 is fixedly connected to a spiral pipe 402. The spiral pipe 402 is integrally spiral-shaped and rising. This shape can increase the contact area between the spiral pipe 402 and water, thereby improving the heat recovery effect. The spiral pipe 402 is located outside the stirring component 306. The other end of the spiral pipe 402 penetrates the right side wall of the water storage tank 301 and is fixed to the right side wall of the water storage tank 301. One end of the spiral pipe 402 far from the water storage tank 301 is fixedly connected to a serpentine pipe 403 that penetrates the heat insulation plate 5. A plurality of heat dissipation fins are fixed on the outer surface of the serpentine pipe 403. The heat dissipation fins can transfer the heat on the serpentine pipe 403 to the heat dissipation fins, increasing the heat dissipation area and further improving the heat dissipation effect. One end of the serpentine pipe 403 far from the spiral pipe 402 penetrates the right inner wall of the box body 1. One end of the serpentine pipe 403 located outside the box body 1 is fixedly connected to a cooling device. Subsequently, using a dedicated cooling device to cool the coolant can ensure the stability of the internal operation of the air compressor.

[0035] In this embodiment, during actual use, the driving motor 302 outputs power to the stirring component 306. Through the mutual cooperation of the connecting spring 3065 and the clamping rod 3066, the intermittent rotation of the blades is realized, thereby improving the stirring effect on the water body.

[0036] Please refer to again Figure 1 and Figures 6 to 7, in order to improve the functionality of the device, the cooling component 6 in this embodiment includes a rotating rod 601 rotatably connected to the inner bottom wall of the box body 1 through a bearing. A threaded hole communicating with the inner cavity of the rotating rod 601 is provided at the top of the rotating rod 601. A blocking cover 602 extending outside the threaded hole is threadedly connected in the threaded hole. When it is necessary to add water to the inner cavity of the rotating rod 601, only by rotating the blocking cover 602 can water be quickly added to the inner cavity of the rotating rod 601. A fan blade 603 is fixed on the outer surface of the rotating rod 601. The rotation of the fan blade 603 can promote air circulation. A stabilizing ring is fixed on the outer side of the fan blade 603. The outer side of the stabilizing ring is rotatably connected to a stabilizing seat 604 through a bearing. The cooperation between the stabilizing ring and the stabilizing seat 604 can effectively improve the stability of the fan blade 603. The left and right sides of the stabilizing seat 604 are respectively fixed to the right side wall of the heat insulation plate 5 and the inner right wall of the box body 1. A spraying part 605 communicating with the inner cavity of the rotating rod 601 is provided on the outer surface of the rotating rod 601.

[0037] Furthermore, the transmission component 307 includes a driving sprocket fixed on the outer surface of the transmission rod 305. A chain is movably connected to the outer surface of the driving sprocket. Using chain transmission can ensure transmission stability. And for sprocket transmission, a driven sprocket is fixed on the outer surface of the rotating rod 601. Power is transmitted between the driving sprocket and the driven sprocket through the chain. The chain penetrates through the heat insulation plate 5.

[0038] It can be known that the spraying part 605 includes water storage pipes 6051 fixedly connected and communicated with the left and right sides of the rotating rod 601. A blocking plate 6052 is fixed inside each water storage pipe 6051. A water flow hole penetrating through the blocking plate 6052 is provided on each blocking plate 6052. The position of the water flow hole is set relatively high, which can ensure that when the water storage pipe 6051 rotates, water can smoothly pass through under the action of centrifugal force, and at the same time play a role in blocking the water flow to prevent water from flowing out when it is not rotating. Atomizing nozzles 6053 are fixedly connected and communicated with the opposite sides of the two water storage pipes 6051. Both water storage pipes 6051 are communicated with the inner cavity of the rotating rod 601.

[0039] It should be further noted that an annular groove is formed in the bottom of the box body 1, and a plurality of support springs 701 are fixed to the inner top wall of the annular groove. The support springs 701 are in a stretched state and can provide a certain pulling force for the connecting plate 702. The bottoms of the plurality of support springs 701 are fixed with a connecting plate 702, and the bottom of the connecting plate 702 is fixed with a dust-proof net 703. The dust-proof net 703 can effectively block dust and ensure that the inside of the box body 1 is in a relatively clean state. Four stabilizing holes are formed in the inner wall of the box body 1, and a connecting rod 704 extending outside the stabilizing hole is movably connected in each stabilizing hole. Each connecting rod 704 passes through the connecting plate 702, and an abutting ring that abuts against the bottom of the connecting plate 702 is fixed on the outer surface of each connecting rod 704 and below the connecting plate 702. By abutting the connecting plate 702 upward through the abutting ring and cooperating with the abutting between the inner top wall of the annular groove and the top of the connecting plate 702, the stability of the dust-proof net 703 can be effectively improved. A connecting platform 705 is fixed between every two connecting rods 704 and inside the box body 1, and a floating chamber 706 is fixed on the top of each connecting platform 705. Each floating chamber 706 is filled with helium. Helium is an inert gas, not prone to chemical reactions, with high stability. At the same time, its own density is relatively low, and it can provide good buoyancy.

[0040] In this embodiment, when the driving motor 302 is started forward, due to the action of the fan blade 603, the air flows upward at this time. With the buoyancy of the floating chamber 706 and the pulling force of the support spring 701, the stability of the dust-proof net 703 can be effectively improved, and the shaking of the dust-proof net 703 can be reduced. When dust removal is required, the driving motor 302 is started in reverse, and the floating chamber 706 is forced to move downward by the wind force. At this time, the abutting ring loses the abutting force with the connecting plate 702. Due to the instability of the support spring 701 itself and the cooperation with the downward wind force, the dust-proof net 703 is smoothly shaken, further realizing the dust removal effect.

[0041] It can be understood that the device realizes heat recovery by heating water, realizes sufficient agitation of the water through the stirring assembly 306, and ensures that the water flow is not too fast, improving the heat dissipation effect of the spiral tube 402. Then, in cooperation with the cleaning assembly 7 and the cooling assembly 6, multiple functions such as providing heating, reducing the subsequent cooling workload, and cleaning the dust-proof net 703 can be realized.

[0042] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection of the present invention will not be further explained in detail.

[0043] The working principle of the above embodiment is as follows:

[0044] (1) During use, first, the coolant flowing out of the air compressor enters the spiral tube 402 through the liquid inlet pipe 401. At the same time, the driving motor 302 transmits the power from the transmission rod 305 to the driving rod 3061 of the stirring assembly 306. At this time, under the action of the connecting spring 3065, a part of the clamping rod 3066 is located in the clamping groove, and the other part is located in the spring groove. At this time, the connecting ring 3064 rotates with the driving rod 3061, and multiple driven gears 3069 are locked. Due to the meshing relationship between the driven gear 3069 and the inner wall of the protective shell 3062, the protective shell 3062 will also drive the blades to rotate together at this time, thereby stirring the water.

[0045] (2) When the rotational speed of the transmission rod 305 reaches the normal speed, due to the centrifugal force, at this time, multiple clamping rods 3066 will move outwards. When the clamping rod 3066 completely disengages from the clamping groove, the power cannot be directly transmitted to the connecting ring 3064. At this time, due to the resistance of the water to the blades on the outside of the protective shell 3062, the speed of the protective shell 3062 will decrease. At this time, the driven gear 3069 will rotate self - simultaneously around the driving gear 3063 under the action of the driving gear 3063. Since the revolution speed is much lower than the initial rotational speed of the connecting ring 3064, the centrifugal force decreases at this time. Under the action of the connecting spring 3065, the clamping rod 3066 will move towards the inner side of the clamping groove. When the clamping rod 3066 moves into the clamping groove, it will return to the original locked state again. By repeating the above process, intermittent variable - speed rotation of the blades in the water can be achieved, improving the water circulation effect, further enhancing the heat absorption of water, and improving the waste heat recovery effect.

[0046] (3) The coolant after releasing heat enters the serpentine tube 403. If hot air needs to be collected, water does not need to be injected into the rotating rod 601. Then the air passes through the fan blade 603 and flows through the serpentine tube 403, taking away the heat on the serpentine tube 403 and being blown out from above the box body 1. Only the hot air above the box body 1 needs to be collected for heating, etc. If hot air does not need to be collected, water can be directly injected into the rotating rod 601. The rotation of the fan blade 603 drives the air to circulate. At the same time, due to the centrifugal force, the water in the rotating rod 601 enters the water storage pipe 6051 and passes through the flow holes through the baffle 6052. Due to the action of the atomizing nozzle 6053, the water will be sprayed out as water mist. Along with the air flow, it adheres to the serpentine tube 403 and takes away heat through evaporation, reducing the workload of subsequent cooling.
