[0002] With the rapid development of my country's economy and the advancement of industrialization, energy consumption in the industrial field has continued to grow, and a large part of the energy is discharged into the environment in the form of waste heat.

[0022] In this embodiment, a guide rod 13 is fixedly connected between the two sides of the middle part of the heat exchange box 3, and the same screw plate 14 is slidably sleeved on the circumferential surface of the two guide rods 13, and both ends of the screw plate 14 are provided with circular holes that are compatible with the guide rods 13, and both ends of the bottom of the screw plate 14 are fixedly connected with U-shaped sliding plates 15, and each U-shaped sliding plate 15 is slidably sleeved in two adjacent heat exchange tubes 402, and each U-shaped sliding plate 15 is provided with two circular holes that are compatible with the heat exchange tubes 402.

[0024] In this embodiment, one end of the reciprocating screw 12 close to the plug plate 9 passes through the heat exchange box 3 and is fixedly connected to the rotating rod 5, and the other end of the rotating rod 5 passes through the adjacent bending tube 4 and is fixedly connected to the propeller 501. Through the setting of the propeller 501, the water flow can drive the reciprocating screw 12 and the rotating rod 6 to rotate. A circular hole matching the rotating rod 5 is opened on the bending tube 4, and the rotating rod 5 is located on the outside of the heat exchange box 3 and is also fixedly sleeved with a bevel spur gear 502.

[0025] In this embodiment, the outer end of the top of the connecting plate 7 is rotatably connected to a rotating rod 6, and a bevel gear 602 is fixedly connected to the top of the rotating rod 6, and the bevel gear 602 is meshed with the bevel spur gear 502. Two fixed blocks 601 are rotatably sleeved on the circumferential surface of the rotating rod 6, and the two fixed blocks 601 are fixedly connected to the outer wall of the heat exchange box 3. A first synchronous wheel 603 is fixedly sleeved on the bottom of the rotating rod 6, and the same synchronous belt 604 is sleeved between the first synchronous wheel 603 and the second synchronous wheel 801. Through the setting of the synchronous belt 604, the first synchronous wheel 603 and the second synchronous wheel 801, the rotation of the rotating rod 6 drives the rotation of the round rod 8, and then drives the four plug-in plates 9 to operate.

[0026] In this embodiment, an air outlet pipe 302 is fixedly connected to a side of the top of the heat exchange box 3 close to the water tank 1 , and an air inlet pipe 301 is fixedly connected to a side of the heat exchange box 3 away from the water tank 1 .

[0027] In this embodiment, a circulation pump 2 is fixedly arranged in series on the connecting pipe 201 near the plug plate 9, and the circulation pump 2 is fixedly connected to the outer wall of the water tank 1. The outer wall of the water tank 1 is provided with an insulation layer. A water outlet pipe and a control valve are provided on one side of the outer wall of the water tank 1 to facilitate the use of water. The four corners at the bottom of the water tank 1 are fixedly connected with a support frame 102, and a water inlet 101 is provided at the top of the water tank 1.

[0028] Working principle: When in use, add enough water to the water tank 1, start the circulation pump 2, so that the water inside the water tank 1 circulates through the four heat exchange tubes 402, connect one end of the air inlet pipe 301 to the boiler flue gas, and one end of the air outlet pipe 302 to the chimney, and the flue gas enters the heat exchange box 3. Through the arrangement of the two lower plates 10 and the upper plate 11, the stroke inside the heat exchange box 3 becomes larger, which is convenient for the heat exchange tube 402 to fully contact with the flue gas and absorb heat. Through the circulation of water, the heat is brought into the water tank 1. The outer side of the water tank 1 has an insulation layer to keep the water flow warm. Since the water speed in the connecting pipe 201 is relatively fast, it will pass through the propeller 501, causing the rotating rod 5 and the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, the screw plate 14 moves back and forth with the U-shaped sliding plate 15 to remove dust from the surfaces of the four heat exchange tubes 402, so that the outer wall of the heat exchange tube 402 is in full contact with the flue gas to absorb heat. The removed dust falls into the guide hood 304 through the conical hood 303. Due to the rotation of the rotating rod 5, under the action of the conical spur gear 502 and the bevel gear 602, the rotating rod 6 also rotates accordingly, under the action of the synchronous belt 604 and the like. The round rod 8 rotates with the U-shaped rotating rod 802. Due to the cooperation of the four U-shaped rotating rods 802 and the strip holes 903, the four plug plates 9 move oppositely to each other. When one plug plate 9 moves outward, the adjacent plug plate 9 will move toward the inside of the material guide cover 304, so that the dust inside the material guide cover 304 gradually falls from the bottom of the material guide cover 304 through the transmission of the four plug plates 9. At the same time, due to the interlaced work of the four plug plates 9 and the high temperature of the flue gas, a large amount of flue gas will not be discharged from the bottom of the material guide cover 304. In this way, the dust on the outer wall of the heat exchange tube 402 is easy to clean, and the dust will not accumulate inside the heat exchange box 3, thereby improving the practicability of the equipment.
