[0033] Example 1

[0034] Referring to Figures 1 to 3, this is the first embodiment of the present application. This embodiment provides a thermal power plant heat energy recovery and utilization device, including a recovery component 100. By setting a main body 101, a rotating component 102 disposed on the outer wall of the main body 101, a plurality of connecting components 103 disposed on the outer wall of the rotating component 102, an adjusting component 104 disposed on the outer wall of the connecting component 103, and a connecting component 105 disposed below the adjusting component 104, the device achieves the function of adjusting the length of the hot air passage.

[0035] Specifically, the recovery component 100 includes a main body 101, a rotating component 102 disposed on the outer wall of the main body 101, a plurality of connecting components 103 disposed on the outer wall of the rotating component 102, an adjusting component 104 disposed on the outer wall of the connecting components 103, and a connecting component 105 disposed below the adjusting component 104; the rotating component 102 can adjust the plurality of connecting components 103 according to the actual liquid level; the adjusting component 104 can adjust the path length of the plurality of connecting components 103 through the connecting component 105.

[0036] The rotating component 102 can adjust the position of the connecting component 103 according to the actual liquid level to adapt to different heating requirements. The connecting component 103 is used to connect the air inlet pipe 102d and the air outlet pipe 102e, and the length of the heat circuit is adjusted by sliding the telescopic pipe 103b. The adjusting component 104 adjusts the position of the connecting component 105 by extending and retracting the electric telescopic rod 104a, thereby adjusting the extension and retraction state of the connecting component 103 to adapt to different heat recovery requirements. The connecting component 105 adjusts the extension and retraction state of the linkage pipe 103a by adjusting the position of the swing rod rotating seat 105b and the swing rod 105c, thereby achieving precise control of the length of the hot air passage.

[0037] Preferably, the main body 101 includes a housing 101a, a support leg 101b at the bottom of the housing 101a, a liquid inlet 101c on one side of the housing 101a, a liquid outlet 101d on the side of the housing 101a away from the liquid inlet 101c, and a mounting bracket 101e on the top of the housing 101a.

[0038] The two adjacent connecting parts 103 are connected to each other; multiple adjusting parts 104 are provided, and the number of adjusting parts 104 is equal to that of connecting parts 105; the housing 101a is preferably a cuboid, but is not limited to other three-dimensional shapes; the support leg 101b is fixedly installed under the housing 101a to support the entire equipment and ensure stable operation, and its shape can be a cylinder, cube, irregular block, or other shapes; the liquid inlet 101c is used to introduce the liquid that needs to be heated, and the liquid outlet 101d is used to discharge the heated liquid; the mounting bracket 101e is used to fix the adjusting parts 104, and the connecting part 105 extends through the top of the housing 101a and into the interior of the housing 101a.

[0039] In summary, by setting the rotating component 102, the connecting component 103 can be rotated and displaced to adapt to different heating heights. By adjusting the state of the connecting component 105 through the adjusting component 104, the extension and retraction state of the connecting component 103 can be adjusted, thereby improving the efficiency of heat energy recovery and utilization in thermal power plants.

[0040] Example 2

[0041] Referring to Figures 1 to 5, this is the second embodiment of the present application. This embodiment is based on the previous embodiment, except that the motor 102a is started, which can cause the first gear 102c to mesh and rotate with the second gear 102f, thereby causing the connecting member 103 to rotate.

[0042] Specifically, the rotating component 102 includes a motor 102a disposed on the outer wall of the housing 101a, a protective shell 102a-1 disposed on the outside of the motor 102a, a rotating shaft 102b disposed at the output end of the motor 102a, and a first gear 102c disposed at one end of the rotating shaft 102b.

[0043] The motor 102a is located on the outer wall of the housing 101a on the side of the liquid outlet 101d. The protective shell 102a-1 can provide protection for the motor 102a and prevent the motor 102a from being impacted by external forces. One end of the rotating shaft 102b is connected to the motor 102a, and the other end is fixedly connected to the first gear 102c. The motor 102a can provide driving force for the rotation of the first gear 102c.

[0044] Preferably, an air inlet pipe 102d is provided above the liquid inlet 101c, and an air outlet pipe 102e is provided above the liquid outlet 101d.

[0045] The air inlet pipe 102d is used to connect to the heat source of the thermal power plant and introduce hot air into the equipment, while the air outlet pipe 102e can discharge the hot air that has undergone heat exchange from the equipment.

[0046] Preferably, the outer wall of the air outlet pipe 102e is fitted with a second gear 102f, and the first gear 102c meshes with the second gear 102f.

[0047] Among them, the air outlet pipe 102e extends through the protective shell 102a-1, the second gear 102f is fixedly sleeved on the outer wall of the air outlet pipe 102e, and the first gear 102c and the second gear 102f are both located inside the protective shell 102a-1.

[0048] Preferably, the plurality of connecting parts 103 include a linkage pipe 103a disposed inside the housing 101a, with telescopic pipes 103b at both ends of the linkage pipe 103a, a fixed pipe 103c slidably disposed on the outer wall of the telescopic pipe 103b, and a connecting horizontal pipe 103d disposed above the fixed pipe 103c.

[0049] Each connecting horizontal tube 103d has a fixed tube 103c connected to both sides of its sidewalls. One end of the telescopic tube 103b extends into the fixed tube 103c and slides with it. The linkage tube 103a is rotatably connected to the telescopic tubes 103b at both ends. The connecting part 103 is in the shape of an "arch" or a trapezoid.

[0050] In summary, by starting the motor 102a, the rotation of the shaft 102b will drive the first gear 102c to rotate. The rotation of the first gear 102c meshes with the second gear 102f, which in turn drives the air outlet pipe 102e to rotate, thereby driving the connecting part 103 to rotate. Thus, the height of the connecting part 103 can be adjusted for different liquid levels.

[0051] Example 3

[0052] Referring to Figures 1 to 6, this is the third embodiment of the present application. This embodiment is based on the previous embodiment, except that the extension length of the telescopic tube 103b of the electric telescopic rod 104a is adjustable.

[0053] Specifically, the adjusting component 104 includes an electric telescopic rod 104a located below the mounting bracket 101e, and a sleeve 104b is provided below the electric telescopic rod 104a.

[0054] Preferably, an adjusting block 104c is movably provided inside the sleeve 104b, an adjusting rod 104d is provided below the adjusting block 104c, and an elastic element 104e is provided above the adjusting block 104c.

[0055] Preferably, the connector 105 includes a slide rod 105a located below the adjusting rod 104d, a rocker arm rotating seat 105b located below the slide rod 105a, a swing rod 105c rotatably located below the rocker arm rotating seat 105b, and a collar 105d located below the swing rod 105c. The collar 105d is movably sleeved on the outer wall of the linkage tube 103a.

[0056] The electric telescopic rod 104a is fixedly installed on the outer wall of the mounting bracket 101e facing the housing 101a; the sleeve 104b is located at the output end of the electric telescopic rod 104a; the adjusting block 104c is fixedly connected to the adjusting rod 104d, one end of the adjusting rod 104d extends out of the sleeve 104b and connects to the slide rod 105a; the adjusting rod 104d and the slide rod 105a are integrally connected; the elastic element 104e is located inside the sleeve 104b, one end is connected to the top of the inner wall of the sleeve 104b, and the other end is connected to the top of the adjusting block 104c; the upper part of the swing rod rotating seat 105b is fixedly connected to the slide rod 105a, and the swing rod rotating seat 105b movably passes through the top of the housing 101a; the top of the swing rod 105c is rotatably connected to the swing rod rotating seat 105b, and can rotate when the rotating part 102 rotates.

[0057] In summary, by activating the electric telescopic rod 104a, the sleeve 104b can be raised or lowered. This allows adjustment of the state of the elastic element 104e, which in turn adjusts the position of the adjusting rod 104d, causing it to rise or fall. This, in turn, causes the sliding rod 105a to rise or fall, which in turn raises or lowers the swing arm rotating seat 105b. This adjusts the state of the swing arm 105c, thereby adjusting the length of the telescopic tube 103b extending out of the fixed tube 103c, and thus adjusting the path length of the hot air.

[0058] In addition, when hot air passes through the equipment, if the pressure of the hot air is high, that is, the surface flux velocity is high, the hot air can push the linkage pipe 103a, causing the extension pipe 103b to extend beyond the fixed pipe 103c by a longer length, thereby automatically adjusting the path length of the hot air.

[0059] Example 4

[0060] Referring to Figure 1, which is the fourth embodiment of this application, this embodiment provides a waste heat recovery system, including any of the thermal power plant heat energy recovery and utilization equipment in the above embodiments. By adopting the waste heat recovery system, the waste heat emitted by the thermal power plant can be recovered and utilized, thereby improving the overall energy utilization efficiency; reducing waste heat emissions and reducing environmental pollution; and the heat exchange conditions can be dynamically adjusted according to the actual operating conditions, thereby improving the flexibility and adaptability of the system.
