[0021] In the present application, two transmission plates 7 are provided on the outer side of the curved pipe 3, and two reciprocating screws 8 are rotatably connected to the outer sides of the two transmission plates 7. Scraper rods 9 are spirally driven on the outer sides of the two reciprocating screws 8. The two scraper rods 9 are symmetrically distributed and the scraping hairs on the two scraper rods 9 are in contact with the curved pipe 3. Gears 10 are fixedly provided on the outer sides of the two reciprocating screw rods 8. A gear ring 11 is fixedly connected to the left inner wall of the heat exchange box 1, and the two gears 10 are meshed with the gear ring 11. By setting the scraper rod 9, the curved pipe 3 drives the transmission plate 7 to rotate, the transmission plate 7 drives the reciprocating screw rod 8 to rotate, and the reciprocating screw rod 8 drives the gear 10 to rotate. When the gear 10 rotates, it is limited by the gear ring 11 to form self-rotation. The self-rotation of the gear 10 drives the reciprocating screw rod 8 to rotate, and the reciprocating screw rod 8 drives the scraper rod 9 to move back and forth left and right. When the scraper rod 9 moves back and forth left and right, the surface of the curved pipe 3 can be cleaned to avoid the formation of scale on the surface of the curved pipe 3 that affects the heat exchange effect.

[0022] In the present application, four guide rollers 12 are fixedly connected to the opposite sides of the two transmission plates 7, and the two scraper rods 9 are respectively slidably connected to the four guide rollers 12; by setting the guide rollers 12, when the scraper rod 9 moves back and forth left and right, the guide rollers 12 can be used to enable the scraper rod 9 to maintain horizontal lateral movement to avoid deviation, and at the same time, the formation of heel rotation between the scraper rod 9 and the reciprocating screw rod 8 can be avoided.

[0024] In the present application, a thermometer 14 is fixedly installed on the rear side of the heat exchange box 1, an observation hole is opened on the top side of the sealing cover 6, and a double-layer insulating glass 15 is fixedly installed on the inner wall of the observation hole; by arranging the thermometer 14 and the double-layer insulating glass 15, the temperature of the heat exchange liquid after heat exchange can be obtained by observing the thermometer 14, and at the same time, the double-layer insulating glass 15 can be used to timely observe the heat exchange conditions inside the heat exchange box 1, thereby improving the convenience of use.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings.

The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0026] The implementation principle of a waste heat recovery and utilization device in the embodiment of the present application is as follows: when in use, high-temperature gas flows in the curved pipe 3, and at this time the output shaft of the motor 2 cooperates with the sprocket 4 and the chain 5 to drive the curved pipe 3 to rotate. During the rotation of the curved pipe 3, heat will be exchanged with the liquid in different areas injected into the heat exchange box 1, so that the heat exchange box 1 can be evenly exchanged. At the same time, the rotation of the curved pipe 3 can accelerate the fluidity of the heat exchange liquid, so that the heat exchange liquid can be evenly heated up. This also avoids the situation where the local heat exchange liquid temperature is too high and the heat exchange efficiency is reduced. The curved pipe 3 drives the transmission plate 7 to rotate, the transmission plate 7 drives the reciprocating screw 8 to rotate, the reciprocating screw 8 drives the gear 10 to rotate, and the gear 10 is limited by the gear ring 11 to form self-rotation when rotating, and the self-rotation of the gear 10 drives the reciprocating screw 8 to rotate. The reciprocating screw 8 drives the scraper rod 9 to move back and forth left and right. When the scraper rod 9 moves back and forth left and right, the surface of the bent pipe 3 can be cleaned to avoid scale accumulation on the surface of the bent pipe 3 affecting the heat exchange effect. When the scraper rod 9 moves back and forth left and right, the guide roller 12 can be used to keep the scraper rod 9 in horizontal lateral movement to avoid deviation. At the same time, the formation of a follow-up rotation between the scraper rod 9 and the reciprocating screw 8 can be avoided. The bent pipe 3 drives the paddle 13 to rotate. When the paddle 13 rotates, the fluidity of the heat exchange liquid in the heat exchange box 1 can be further improved, thereby ensuring that the heat exchange liquid can be evenly heated during the heat exchange process, ensuring the heat exchange effect. The temperature of the heat exchange liquid after the heat exchange can be obtained by observing the thermometer 14. At the same time, the double-layer insulating glass 15 can be used to timely observe the heat exchange situation inside the heat exchange box 1, thereby improving the convenience of use.
