The structural characteristics of the temperature conducting pipe 29 can greatly improve the travel path of the heat exchange liquid, so that the heat in the flue gas can be more fully introduced into the heat transfer medium in the heat exchange filling cavity 7, and the heat transfer medium is heat transfer oil; In this embodiment, both ends of the transmission tube 30 are fixedly connected with guide seats, the top of the guide seats is fixedly connected with limit rods, both ends of the positioning plate 33 are provided with limit holes, and there is a clearance fit between the limit holes and the limit rods. By setting the limit rods and the limit holes, before the positioning plate 33 is placed, the limit holes are first aligned with the limit rods, so that the assembly position of the positioning plate 33 is guided by the limit rods, thereby ensuring the assembly accuracy of the positioning plate 33; The stabilization component includes a positioning shaft 36, a blocking plate 37, a linkage slot 38 and a positioning seat 39. Both ends of the top of the transmission tube 30 are fixedly connected with the positioning shaft 36, and the outer sides of the two positioning shafts 36 are rotatably connected with the blocking plates 37. The middle of the blocking plate 37 is provided with a linkage slot 38. The top of the transmission tube 30 is fixedly connected with the positioning seat 39, and the top of the positioning seat 39 is slidably connected with a guide slide 40. The middle of the guide slide 40 is fixedly connected with a positioning piece 41, and a spiral spring 42 is fixedly connected between the positioning piece 41 and the positioning seat 39. One end of the guide slide 40 is fixedly connected with a transmission plate 43, and the two ends of the transmission plate 43 are respectively movably connected to the inside of the two linkage slots 38. In this embodiment, both ends of the transmission plate 43 are fixedly connected with linkage columns, and the transmission plate 43 is movably connected to the inside of the linkage slot 38 through the linkage columns, and wear-resistant pads are provided on the outside of the linkage columns; In this embodiment, the opening of the temperature conducting pipe 29 is connected to the converging pipe through a square pipe.

[0021] A specific application of the above two embodiments is: Smoke is introduced into the temperature-conducting cavity 3 through the smoke inlet pipe, and heat is introduced into the heat exchange medium through the heat transfer medium, so that the heat exchange medium is heated up; By connecting the external liquid pipeline with the transmission pipe 30 and coordinating the connection between the liquid supply pipe 31 and the temperature conducting pipe 29, the heat exchange liquid can be transferred into the liquid supply pipe 31 through the transmission pipe 30. Before the heat exchange liquid enters the liquid supply pipe 31, the multi-layer filter plate 35 can be used to filter out impurities in the heat exchange liquid so that the heat exchange liquid can enter the temperature conducting pipe 29. The structural characteristics of the temperature conducting pipe 29 can increase the contact time between the heat exchange liquid and the heat exchange pipe 5, so that the heat exchange liquid can perform effective heat exchange. After the smoke in the temperature conducting chamber 3 is discharged, the transmission motor 18 is started to drive the transmission screw 17 to rotate. Under the connection between the transmission screw 17 and the transmission shaft 20, the transmission shaft 20 can drive the support frame 19 to move vertically. Since the linkage rod 22 is connected between the sealing plate 13 and the guide ear 21, when the guide ear 21 moves vertically, the sealing plate 13 can be pushed by the linkage rod 22, so that the sealing plate 13 moves under the limit of the linear slide bar 12, so as to expose the cleaning window 11 and move the cleaning ring 14 to the specified position inside the temperature conducting chamber 3, and then the electric push rod 24 is started to cause the positioning card rod to disengage from the matching lock. The hole enables the transmission shaft 20 to rotate on the support frame 19, and then when the subsequent transmission screw 17 rotates, it can drive the transmission shaft 20 to idle at the support frame 19, and cooperate with the connection between the two transmission bevel gears 28 to transmit the power of the transmission shaft 20 to the descaling shaft 25, so that the descaling shaft 25 drives the eccentric plate 26 to rotate, and because the driving rod 27 is connected between the eccentric plate 26 and the linkage plate 15, when the eccentric plate 26 rotates, it can push the linkage plate 15 through the driving rod 27, so that the cleaning ring 14 slides back and forth on the outer side of the heat exchange tube 5, so as to clean the tar and other substances on the surface of the heat exchange tube 5; The guide slide bar 40 can be pulled to pull the transmission plate 43 to move laterally, and cooperate with the connection between the transmission plate 43 and the linkage slot 38. When the transmission plate 43 is displaced, the adaptive displacement of the transmission plate 43 inside the linkage slot 38 can be used to pull the blocking plate 37 until the blocking plate 37 is disengaged from the surface of the positioning plate 33, thereby unlocking the positioning plate 33, and then removing the positioning plate 33 from the notch 32 to clean the filter plate 35. When the guide slide bar 40 is pulled, the spiral spring 42 can be squeezed through the positioning sheet 41. When the guide slide bar 40 is subsequently released, the transmission plate 43 can be cooperated with the rebound of the transmission plate 43 to push the transmission plate 43 back to the initial position, so that the blocking plate 37 returns to the top of the positioning plate 33 to block the positioning plate 33.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
