[0002] Flue gas waste heat recovery refers to the process of extracting energy from high-temperature flue gas in the production process and reusing it. Normally, a large amount of heat is generated when fuel is burned, and this heat will be discharged into the atmosphere with the flue gas. If this part of the heat is not recovered, it will cause a waste of energy. Flue gas waste heat recovery is to effectively collect and transform this part of waste heat so that it can become a usable energy source again. In daily use, the flue gas needs to be heat-recovered.

[0025] refer to Figure 3 The cooling mechanism 4 includes a box body 401, an air outlet 402, a cooling copper tube 403, a partition plate 404 and a filter plate 405.

[0034] By adopting the above solution, by providing the connecting pipe 3, it is possible to facilitate heat conduction when water vapor is input, thereby saving energy consumption of the cooling equipment.

[0035] The working principle of this utility model:

[0036] When in use, smoke is input from the smoke exhaust pipe 1 into the interior of the heating tank 2, and the internal water source of the heating tank 2 is heated by the smoke. When heated to a certain temperature, a large amount of water vapor is generated, and the water vapor is carried to the interior of the box body 401 through the connecting pipe 3. When the water vapor contacts the cooling copper tube 403, the temperature drops rapidly, and a large amount of water droplets condense on the surface of the cooling copper tube 403. Due to the influence of gravity, they slide into the interior of the water collecting box 5 through the filter plate 405. The cooled water vapor is discharged through the top air outlet 402. After cleaning the water inside the water collecting box 5, turn counterclockwise. By rotating the rotating rod 801, the surface of the fixed column 802 is squeezed through the inside of the stroke groove 11 to move the fixed column 802 downward, and the connecting rod 803 is driven downward by the fixed column 802. The connecting rod 803 drives the positioning rod 804 to move downward according to the moving trajectory provided by the limiting groove 10. While the positioning rod 804 moves downward, the tension spring 805 is stretched to move the positioning rod 804 to the inside of the positioning cavity 7. At this time, the accumulated water can be cleaned up. After completion, the moving rod is released, and the positioning rod 804 is reinserted into the inside of the fixed groove 9 through the return force of the tension spring 805.

[0037] To sum up: the smoke exhaust pipe heat exchange device, through the arrangement of a smoke exhaust pipe 1, a heating tank 2, a connecting pipe 3, a cooling mechanism 4, a box 401, an air outlet 402, a cooling copper tube 403, a partition plate 404, a filter plate 405, a water collecting box 5, a water outlet 6, a positioning cavity 7, a positioning mechanism 8, a rotating rod 801, a fixing column 802, a connecting rod 803, a positioning rod 804, a tension spring 805, a fixing groove 9, a limiting groove 10, a travel groove 11 and a barometer 12, solves the problem that the existing equipment cannot process the heated water vapor, which easily leads to excessive pressure and operational risks. In order to be able to process the water vapor, a smoke exhaust pipe heat exchange device is proposed, which can fully cool the emitted water vapor when recovering the heat energy of the flue gas to reduce the safety risk.
