[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. When the flue gas temperature is high, the arc-shaped heat absorption plate rotates upward and covers the middle of the flue gas treatment box. The flue gas flows from bottom to top through the bottom of the arc-shaped heat absorption plate and the ventilation slot, increasing the contact area and residence time between the flue gas and the heat absorption plate.

[0022] 2. The ventilation slot design allows flue gas to penetrate into the interior of the arc-shaped heat absorption plate. Combined with the opening of the connecting slot of the sliding storage arc plate, the heat absorption efficiency is further improved, the heat is absorbed more fully, and the loss is reduced.

[0023] 3. The moving pulley is squeezed by the inner wall of the flue gas treatment box, compressing the fixed support spring, causing the sliding storage arc plate to slide and connect with the ventilation slot, so as to perform directional heat absorption on the outer area of ​​the top of the flue gas treatment box, and the overall waste heat recovery rate is significantly improved.

[0024] 4. When the flue gas temperature is low, the arc-shaped heat absorption plate rotates downward to form an arc-shaped cover at the top of the flue pipe, directly wrapping the flue gas outlet, reducing heat loss to the outside, maintaining a stable flue gas temperature, and the sliding storage arc plate slides outward to misalign the connecting groove and the ventilation groove, sealing the bottom of both sides of the arc-shaped heat absorption plate, minimizing the heat dissipation path, improving heat preservation efficiency, preventing the low-temperature flue gas from cooling too early, ensuring the high efficiency of the waste heat recovery process, and reducing additional energy consumption.

[0025] 5. Through the waste heat recovery component, the heat absorbed by the arc-shaped heat absorption plate is transferred to the water. The water flows in the heat absorption tube frame and carries away the heat. The heat flows back to the liquid storage tank with the water, realizing the storage and subsequent utilization of waste heat and reducing energy waste. Attached Figure Description

[0048] The storage cavity 601 is located on the left side inside the arc-shaped heat absorption plate 504. The fixed support spring 602 is fixedly connected to the right side inside the storage cavity 601. The sliding storage arc plate 603 is fixedly connected to the left end of the fixed support spring 602.

[0050] The bottom and top of the arc-shaped heat-absorbing plate 504 are provided with interconnected ventilation slots, and the top and bottom of the sliding storage arc plate 603 are provided with corresponding connecting slots, which are the same size as the ventilation slots.

[0051] Example 3, please refer to Figure 8-10 Based on Embodiment 2, the present invention provides a technical solution that further includes a waste heat recovery component 7, which is composed of a heat absorption tube frame 701, a storage connecting pipe 702, a spring connecting pipe 1 703, a support tube frame 704, a water pump 705, a liquid outlet connecting pipe 706, a liquid storage tank 707, a spring connecting pipe 2 708, and a liquid return pipe 709.

[0052] The heat absorption tube frame 701 is fixedly connected to the top of the arc-shaped heat absorption plate 504. The storage connecting pipe 702 is fixedly connected to the inside of the heat absorption tube frame 701. The first spring connecting pipe 703 is fixedly connected to the back of the storage connecting pipe 702. The support tube frame 704 is fixedly connected to the rear end of the first spring connecting pipe 703. The water pump 705 is fixedly connected to the back of the support tube frame 704. The liquid outlet connecting pipe 706 is fixedly connected to the back of the water pump 705. The liquid storage tank 707 is fixedly connected to the end of the liquid outlet connecting pipe 706 away from the water pump 705. The second spring connecting pipe 708 is fixedly connected to the left side of the back of the heat absorption tube frame 701. The liquid return pipe 709 is fixedly connected to the rear end of the second spring connecting pipe 708.

[0053] The end of the liquid return pipe 709 away from the spring connecting pipe 708 is fixedly connected to the front of the liquid storage tank 707. The spring connecting pipe 708, the liquid return pipe 709 and the liquid storage tank 707 are connected internally. The liquid storage tank 707 is filled with water, which can guide the heat absorbed by the heat absorption tube frame 701 into the liquid storage tank 707 through the spring connecting pipe 708 and the liquid return pipe 709.

[0054] The liquid storage tank 707 is fixedly connected to the outer wall of the flue gas treatment box 3 on the side closest to the flue gas treatment box 3. The support pipe frame 704, away from the spring connecting pipe 703, passes through the flue gas treatment box 3 and extends to the outside of the flue gas treatment box 3, where it is fixedly connected to the water pump 705, thus providing fixed support for the support pipe frame 704.

[0055] When the heating boiler 1 is working, the generated flue gas is sprayed outward through the flue pipe 2 and the flue gas treatment box 3. When the temperature inside the flue gas treatment box 3 is high, in order to improve the waste heat recovery efficiency, the hydraulic lifting rod 401 is controlled to work. When the hydraulic lifting rod 401 works, it drives the lifting sliding plate 403 to rise upward in the lifting guide cylinder 402. When the lifting sliding plate 403 rises, the lifting extrusion frame 501 on the lifting sliding plate 403 pulls the rotating connecting arm plate 502, so that the connecting rotating frame 503 on the other side of the rotating connecting arm plate 502 is subjected to force, and the arc-shaped heat absorption plate 504 at the bottom of the connecting rotating frame 503 is subjected to force simultaneously. At this time, the rotating connecting block 505 on the arc-shaped heat absorption plate 504 can be positioned on the outside of the fixed circular plate 404 and rotated at the positioning frame 405. The internal rotation allows the rotating connecting block 505 and the arc-shaped heat absorption plate 504 to rotate upward within the positioning rotating frame 405. This allows the arc-shaped heat absorption plate 504 and the rotating connecting block 505 to be on the same horizontal line as the fixed circular plate 404 and the positioning rotating frame 405. At this time, the arc-shaped heat absorption plate 504 opens relative to the fixed circular plate 404, covering the middle of the flue gas treatment box 3. This allows the flue gas flowing from bottom to top in the flue gas treatment box 3 to pass through the bottom of the arc-shaped heat absorption plate 504 and flow upward through the ventilation slots on the arc-shaped heat absorption plate 504. This allows the heat in the flue gas to be absorbed by the arc-shaped heat absorption plate 504. At the same time, due to the ventilation slots, the flue gas can penetrate into the interior of the arc-shaped heat absorption plate 504 during the flow process, making the heat absorption efficiency of the arc-shaped heat absorption plate 504 higher and improving the efficiency of waste heat recovery.

[0056] When the arc-shaped heat-absorbing plate 504 rotates upward within the positioning rotating frame 405, the inner wall of the flue gas treatment box 3 presses against the movable pulley 605, causing the movable pulley 605 to roll on the inner wall of the flue gas treatment box 3. At the same time, the sliding receiving arc plate 603 is subjected to force, which compresses the fixed support spring 602. Simultaneously, the sliding receiving arc plate 603 slides within the arc-shaped heat-absorbing plate 504, allowing the connecting groove on the sliding receiving arc plate 603 to connect with the ventilation groove. This enables the outer top of the arc-shaped heat-absorbing plate 504 to recover heat from the flue gas from bottom to top, improving the waste heat recovery efficiency.

[0057] When the temperature of the flue gas introduced into the flue gas treatment box 3 through the flue pipe 2 is low, it is necessary to reduce the heat dissipation from the residual heat. At this time, the hydraulic lifting rod 401 is controlled to work. When the hydraulic lifting rod 401 is working, it pushes the lifting sliding plate 403 down, which allows the lifting pressing frame 501 to press the rotating connecting arm plate 502 when the lifting sliding plate 403 is descending. This causes the rotating frame 503 connected to the other side of the rotating connecting arm plate 502 to be stressed. At this time, the arc-shaped heat absorption plate 5 on the other side of the rotating frame 503 is subjected to force. The force 04 allows the rotating connecting block 505 on the arc-shaped heat absorption plate 504 to rotate downwards within the positioning rotating frame 405 outside the fixed circular plate 404. This allows the arc-shaped heat absorption plates 504 on both sides of the positioning rotating frame 405 to rotate simultaneously outside the fixed circular plate 404. This enables the two arc-shaped heat absorption plates 504 to form an arc at the bottom of the flue gas treatment box 3 and cover the air outlet at the top of the flue gas pipe 2. This maximizes the heat preservation of the flue gas emitted from the flue gas pipe 2 and ensures the efficiency of waste heat recovery.

[0058] When the hydraulic lifting rod 401 controls the arc-shaped heat absorption plate 504 to rotate outside the positioning rotating frame 405, it prevents the inner wall of the flue gas treatment box 3 from squeezing the moving pulley 605. At this time, the fixed support spring 602 elastically recovers within the arc-shaped heat absorption plate 504, allowing the fixed support spring 602 to push the sliding receiving arc plate 603 to slide outward within the arc-shaped heat absorption plate 504. When the sliding receiving arc plate 603 moves, the connecting groove and ventilation groove on the sliding receiving arc plate 603 are misaligned, causing the arc-shaped heat absorption plate 504 to be sealed near the outer side. This seals the bottom of both sides of the arc-shaped heat absorption plate 504, further improving the heat preservation efficiency and making the waste heat recovery efficiency of the device higher during use.

[0059] After the arc-shaped heat absorption plate 504 absorbs the heat from the flue gas treatment box 3, the water pump 705 is controlled to work, which allows the water in the liquid storage tank 707 to be extracted and introduced into the storage connection pipe 702 through the liquid outlet connection pipe 706, the water pump 705, the support pipe frame 704 and the first spring connection pipe 703. This allows the water in the storage connection pipe 702 to enter the heat absorption pipe frame 701 and flow in the heat absorption pipe frame 701, which can carry away the heat absorbed by the heat absorption pipe frame 701. The water then flows back to the liquid storage tank 707 through the second spring connection pipe 708 and the liquid return pipe 709, thus storing the recovered waste heat.
