[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a compressor waste heat recovery device, which can achieve the effect of absorbing the heat of the piston cylinder 2 inside the compressor body 1. It includes the compressor body 1 and the piston cylinder 2 disposed at the end of the compressor body 1.

[0033] Specifically, the waste heat absorption assembly 3 installed inside the compressor body 1 includes a heat absorption component 31 installed at the end of the compressor body 1 and a water exchange component 32 installed at the end of the heat absorption component 31.

[0034] Furthermore, piston cylinders 2 are installed at both ends inside the compressor body 1;

[0035] The piston cylinder 2 is equipped with a stroke piston. One reciprocating motion of the stroke piston in the piston cylinder 2 constitutes a complete stroke.

[0036] The waste heat absorption assembly 3 is installed inside the compressor body 1 and located on the outer wall of the piston cylinder 2. The waste heat absorption assembly 3 includes a heat absorption element 31 and a water exchange element 32. The heat absorption element 31 is installed inside the compressor body 1, and the water exchange element 32 is installed on the surface of the compressor body 1. The water exchange element 32 is connected to the heat absorption element 31.

[0037] Specifically, the heat-absorbing component 31 includes a heat-absorbing tube 311 disposed on the surface of the piston cylinder 2;

[0038] Furthermore, the heat-absorbing component 31 includes a heat-absorbing tube 311 mounted on the surface of the piston cylinder 2. The heat-absorbing tube 311 is located inside the compressor body 1 and is attached to the surface of the piston cylinder 2.

[0039] Specifically, the water exchange component 32 includes a water chamber 321 disposed at the end of the compressor body 1 and a water outlet assembly 322 and a water inlet assembly 323 disposed at the end of the water chamber 321;

[0040] Furthermore, the water exchange component 32 includes a water chamber 321 installed at the end of the compressor body 1 and a water outlet assembly 322 and a water inlet assembly 323 respectively installed at the upper and lower ends of the water chamber 321.

[0041] Specifically, the two ends of the heat absorption tube 311 are connected to the water outlet group 322 respectively.

[0042] Furthermore, both ends of the heat absorption tube 311 are connected to the water outlet assembly 322. The heat absorption tube 311 has a hollow internal structure and is made of copper, a material with good thermal conductivity. Both ends of the heat absorption tube 311 are connected to the water outlet assembly 322 of the water cavity 321. The water inlet assembly 323 introduces coolant into the water cavity 321. Then, the coolant enters the heat absorption tube 311 from the water cavity 321 through the water outlet assembly 322.

[0043] Specifically, the heat absorption pipe 311 consists of multiple S-shaped pipes connected end to end, and a connecting pipe 312 is provided at the end of the heat absorption pipe 311.

[0044] Furthermore, the heat absorption pipe 311 consists of multiple S-shaped pipes connected end to end. The heat absorption pipe 311 is attached to the outside of the piston cylinder 2 in a continuous S-shaped disc. The end of the heat absorption pipe 311 is provided with a connecting pipe 312, which is fixed inside the compressor body 1. The connecting pipe 312 is equipped with two independent through holes, which are respectively connected to the two ends of the heat absorption pipe 311. The heat absorption pipe 311 and the connecting pipe 312 are fixed to the outside of the piston cylinder 2 as a whole. When the stroke piston inside the piston cylinder 2 makes a complete stroke, the natural gas between the piston cylinder 2 and the stroke piston is compressed first. The natural gas suddenly becomes smaller in volume and its heat increases dramatically. The heat is instantly conducted to the piston cylinder 2 through heat transfer. The compressed natural gas is then drawn out by the one-way valve. Subsequently, the stroke piston makes a return stroke, increasing the space between the piston cylinder 2 and the stroke piston. The remaining natural gas is drawn into the piston cylinder 2 again by another one-way valve. At this time, the heat increase inside the piston cylinder 2 is relatively small.

[0045] Specifically, the water exchange component 32 also includes a water tank 324. The end of the compressor body 1 is provided with a water tank 324, which is connected to the water inlet group 323. The end of the water inlet group 323 is provided with a heat preservation box 325.

[0046] Furthermore, the water exchange component 32 includes a water tank 324. The water tank 324 is installed at the end of the compressor body 1. A water pump is installed inside the water tank 324 to introduce the coolant inside the water tank 324 into the water inlet assembly 323 under a certain pressure. The water tank 324 and the water inlet assembly 323 are connected through a pipe, and the water tank 324 is connected to an external water supply source to maintain the coolant in the water tank 324 at a constant volume. An insulation box 325 is provided at the end of the water inlet assembly 323. The insulation box 325 is connected to the water supply system of the residential area, and the hot water inside the insulation box 325 is delivered to the residential area for use.

[0047] The coolant flows from the water tank 324 to the inlet group 323, to the water chamber 321, to the outlet group 322, to the heat absorption pipe 311 and the connecting pipe 312, and then from another through hole of the connecting pipe 312 into the outlet group 322, to the water chamber 321, to the inlet group 323, and to the insulation box 325.

[0048] Specifically, a trigger element 33 is provided inside the water cavity 321, and the trigger element 33 is located inside the piston cylinder 2.

[0049] Furthermore, a trigger 33 is installed inside the water cavity 321, and the trigger 33 is located between the piston cylinder 2 and the water cavity 321;

[0050] Specifically, the trigger 33 includes a piston groove 331 inside the piston cylinder 2, a pressure piston 332 is provided inside the piston groove 331, a stroke cavity 333 is provided inside the water cavity 321, and a docking plate 334 is provided at the end of the pressure piston 332, with the docking plate 334 located inside the stroke cavity 333.

[0051] Furthermore, the trigger 33 includes a piston groove 331 opened inside the piston cylinder 2. The size of the piston groove 331 is the same as the size of the pressure piston 332. The pressure piston 332 fits into the piston groove 331, and one side surface of the pressure piston 332 is on the same horizontal plane as the inner wall of the piston cylinder 2, so that the volume inside the piston cylinder 2 does not change during normal compression of natural gas. The pressure piston 332 is slidably connected inside the piston groove 331. The water cavity 321 has a stroke cavity 333. The stroke cavity 333 is a rectangular cavity. The end of the pressure piston 332 is connected to a docking plate 334. The width of the docking plate 334 is the same as the width of the stroke cavity 333, and the docking plate 334 moves linearly back and forth in the stroke cavity 333. The docking plate 334 is located inside the stroke cavity 333.

[0052] When the stroke piston performs a natural gas compression operation in the piston cylinder 2, the pressure inside the piston cylinder 2 suddenly increases, pushing the pressure piston 332 to move into the piston groove 331 in the piston cylinder 2 until the pressure piston 332 is in contact with the piston groove 331. When the stroke piston performs a natural gas intake operation in the piston cylinder 2, the pressure inside the piston cylinder 2 suddenly decreases, pulling the pressure piston 332 into the piston cavity in the piston groove 331 until the mating plate 334 of the pressure piston 332 contacts the inner wall of the water cavity 321, thus completing a complete stroke. Similarly, the pressure piston 332 repeats to complete multiple complete strokes.

[0053] Specifically, both the inlet group 323 and the outlet group 322 have two symmetrical water guide holes 338 inside the water cavity 321.

[0054] Furthermore, both the inlet group 323 and the outlet group 322 have two symmetrical, independent, and non-communicating water guide holes 338 inside the water cavity 321. Sealing rings are placed at both ends of the water guide holes 338 and the connecting holes 335 to prevent the coolant from leaking out inside the water guide holes 338 and the connecting holes 335.

[0055] During operation, when the compressor body 1 starts working, the piston inside the piston cylinder 2 begins a complete stroke, compressing the natural gas inside the piston cylinder 2. At this time, the pressure inside the piston cylinder 2 suddenly increases, pushing the pressure piston 332 towards the piston groove 331 within the piston cylinder 2. During this process, the pressure piston 332 pulls the docking plate 334 within the water chamber 321. The docking plate 334 slides between the water inlet group 323 and the water outlet group 322's guide holes 338. The upper and lower groups of guide holes 338 change from a water-blocking area 337 to a connecting hole 335, allowing the coolant in the water tank 324 to be introduced into the heat absorption pipe 311. The original coolant inside the heat absorption pipe 311 is pushed out by the subsequently introduced coolant to the connecting pipe 312 and discharged into the insulation box 325. When the stroke piston performs one natural gas intake operation within the piston cylinder 2, the pressure inside the piston cylinder 2 suddenly decreases, pulling the pressure piston 332 towards the piston groove 331. As piston 31 moves into the piston chamber, the pressure inside piston cylinder 2 suddenly decreases, pushing pressure piston 332 into piston cylinder 2 through piston groove 331. During this process, pressure piston 332 pulls docking plate 334 into water chamber 321. Docking plate 334 slides between water inlet group 323 and water outlet group 322's guide holes 338. The area between the upper and lower guide holes 338 changes from connection hole 335 to water blockage area 337. At this time, water tank 324 will not continuously introduce coolant. Coolant inside heat absorption pipe 311 can stay briefly and continuously absorb heat. When piston cylinder 2 compresses gas and generates a large amount of heat, coolant with a lower temperature is replaced. When piston cylinder 2 draws in gas and generates less heat, coolant stays briefly inside heat absorption pipe 311 and continuously absorbs heat from inside piston cylinder 2, thereby improving the heat absorption efficiency of coolant. The heat generated inside compressor body 1 is converted into heat in cooling water and delivered to residential areas or factories for construction use.

[0056] Example 2, refer to Figures 1 to 5 This is the second embodiment of the present invention, which provides the advantage of backflushing the inside of the heat absorption tube 311.

[0057] Specifically, a backflush member 34 is provided inside the docking plate 334.

[0058] Furthermore, a backflush member 34 is provided inside the docking plate 334, and the backflush member 34 is located inside the water cavity 321;

[0059] Specifically, the backflush member 34 includes a rotating plate 341. The rotating plate 341 is provided on the inner wall of the docking plate 334. A positioning rod 342 is provided on the surface of the rotating plate 341. A first gear 343 is provided at the end of the positioning rod 342. A gear plate 344 is provided on the surface of the first gear 343. The gear plate 344 is located inside the water cavity 321. A driving block 345 is provided on the surface of the positioning rod 342. The driving block 345 is located above the first gear 343. A reciprocating member 35 is provided between the first gear 343 and the driving block 345.

[0060] Furthermore, the backflush member 34 includes a rotating plate 341, a circular cavity is formed inside the docking plate 334, the rotating plate 341 is rotatably connected inside the docking plate 334, the rotating plate 341 rotates inside the circular cavity, a positioning rod 342 is provided on the surface of the rotating plate 341, the positioning rod 342 is installed at the end of the rotating plate 341, the positioning rod 342 penetrates into the circular cavity, a first gear 343 is rotatably connected to the end of the positioning rod 342, a gear plate 344 is meshed with the surface of the first gear 343, the gear plate 344 is fixedly installed on the inner wall of the water cavity 321, a driving block 345 is fixedly connected to the surface of the positioning rod 342, the driving block 345 is located above the first gear 343, and a reciprocating member 35 is provided between the first gear 343 and the driving block 345;

[0061] During operation, when the compressor body 1 starts working, the piston inside the piston cylinder 2 begins a complete stroke, compressing the natural gas inside the piston cylinder 2. At this time, the pressure and temperature inside the piston cylinder 2 rise sharply, pushing the pressure piston 332 into the piston groove 331 within the piston cylinder 2. The heat absorption pipe 311 completes one coolant replacement. During this process, the docking plate 334 and the rotating plate 341 move unidirectionally within the water chamber 321. The first gear 343 at the lower end of the rotating plate 341 meshes and rolls on the gear plate 344. Simultaneously, the first gear 343 rotates on the positioning rod 342 and the drive block 345. Under the action of the reciprocating component 35, the first gear 343 drives the drive block 345 and the positioning rod 342 to rotate, causing the rotating plate 341 to rotate 90 degrees within the docking plate 334. The cross holes 336 on the rotating plate 341 align with the water guide holes 338 on the surface of the docking plate 334, allowing the coolant to flow through. The water flows out through the cross hole 336 from different guide holes 338 of the water outlet group 322, forming a backwashing effect on the heat absorption tube 311. This flushes out the scale generated by the coolant during heating inside the heat absorption tube 311 that has not yet settled. The scale generated by the coolant during heating inside the heating tube will accumulate at the corner of the heat absorption tube 311 and form a dead zone with the water flow when the water flow is constant. The coolant has different flow directions inside the heat absorption tube 311, which will reduce the dead zone inside the heat absorption tube 311 and balance the temperature difference of the coolant in the same heat absorption tube 311. This allows the coolant to flow in a lower temperature when it first enters the heat absorption tube 311, and the coolant that enters first will flow inside the heat absorption tube 311 until it reaches the other end of the heat absorption tube 311. At this time, the coolant with a lower temperature is higher than the coolant that was just entered. This long-term single flow direction can easily lead to uneven temperature inside the heat absorption tube 311, allowing the coolant to absorb the heat generated inside the compressor body 1 to the greatest extent.

[0062] Example 3, referring to Figures 1 to 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides the advantage of orderly control of the internal coolant of the heat absorber tube 311.

[0063] Specifically, the rotating plate 341 has two symmetrically arranged connecting holes 335 and cross holes 336, and the surface of the docking plate 334 has a water blocking area 337 and a water passage area 339.

[0064] Furthermore, the rotating plate 341 has two symmetrically arranged connecting holes 335. The surface of the docking plate 334 has a water blocking area 337 and a water passage area 339. The water passage area 339 is a drainage hole. When the drainage hole is connected with the water guide hole 338, the coolant smoothly enters the water outlet group 322 from the water inlet group 323. The water blocking area 337 on the surface of the docking plate 334 is a sealing rubber structure, which blocks the coolant from entering the water cavity 321 from the water inlet group 323. When the water blocking area 337 on the surface of the docking plate 334 is connected with the water inlet group 323 and the water outlet group 322, the coolant in the water tank 324 cannot be normally introduced into the heat absorption tube 311, and the coolant in the heat absorption tube 311 cannot be discharged. The coolant can stay in the heat absorption tube 311 for a period of time and continue to absorb heat.

[0065] The two intersecting holes 336 are X-shaped and not connected to each other, and the two intersecting holes 336 have a centrally symmetrical structure.

[0066] Specifically, the reciprocating component 35 includes a slot 351, the drive block 345 has a slot 351 on its surface, the first gear 343 has a rectangular groove 352 on its surface, a retaining plate 353 is provided in the rectangular groove 352, and a first spring 354 is provided between the end of the retaining plate 353 and the rectangular groove 352.

[0067] Furthermore, the reciprocating component 35 includes a slot 351, and the surface of the drive block 345 is provided with a continuous slot 351. The slot 351 is a right-angled slot. The surface of the first gear 343 is provided with a rectangular slot 352. A retaining plate 353 is rotatably connected inside the rectangular slot 352. One end of the retaining plate 353 is rotatably connected to the inside of the rectangular slot 352, and a first spring 354 is connected between the other end of the retaining plate 353 and the rectangular slot 352.

[0068] During operation, when the compressor body 1 starts working, the piston inside the piston cylinder 2 begins a complete stroke, compressing the natural gas inside the piston cylinder 2. At this time, the pressure and temperature inside the piston cylinder 2 rise sharply, pushing the pressure piston 332 towards the piston groove 331 within the piston cylinder 2. Simultaneously, the docking plate 334 and the rotating plate 341 move normally along the inner wall of the water chamber 321. Coolant flows normally from the inlet to the connection hole 335 of the docking plate 334 and then to the outlet assembly 322. When the piston begins its next stroke to draw in natural gas, the docking plate 334 and the rotating plate 341 move normally along the inner wall of the water chamber 321. During the stroke, the positioning rod 342 at the lower end of the rotating plate 341 drives the first gear 343 to rotate in opposite directions on the gear plate 344. The end of the clamping plate 353 at the upper end of the first gear 343 pushes the clamping groove 351, causing the first gear 343 to drive the positioning rod 342 and the driving block 345 to rotate 90 degrees. This allows the two intersecting holes 336 to connect with the upper and lower misaligned water guide holes 338. When the piston cylinder 2 completes one stroke, during the stage when the coolant is continuously absorbing heat, the flow direction of the coolant is changed for the next stroke. This helps to regularly adjust the flow direction of the coolant, absorb the maximum amount of heat, and maintain the coolant with a high and stable heat supply for residential areas.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
