Adjacent corrugated plates form airflow or waterflow spaces, which are arranged at intervals. Rigid mesh sheets are respectively fitted onto the corrugated plates on the left and right sides of the airflow space. A first telescopic element and a second telescopic element are disposed on the outside of the flow diversion box. A first telescopic rod, fixedly connected to the rigid mesh sheet on the left side of the airflow space, is connected to the first telescopic element.

[0020] like Figure 1-4 As shown, the sintered ore environmental protection diversion device described in this embodiment includes a diversion box 1 and multiple corrugated plates 2 disposed in the diversion box 1. The corrugated plates 2 are made of stainless steel. An airflow space 3 or a water flow space 4 is formed between adjacent corrugated plates 2. The airflow space 3 and the water flow space 4 are independent and not connected to each other. The airflow space 3 and the water flow space 4 are arranged alternately, that is, two airflow spaces 3 sandwich one water flow space 4. Rigid mesh 5 is respectively provided on the corrugated plates 2 on the left and right sides of the airflow space 3. The rigid mesh 5 is woven from steel wire.

[0021] The outer side of the flow guide box 1 is provided with a first telescopic element 6 and a second telescopic element 7. The first telescopic element 6 is connected to a first telescopic rod 8 which is fixedly connected to the rigid mesh 5 on the left side of the airflow space 3. When the first telescopic rod 8 moves, it only drives the rigid mesh 5 on the left side of the airflow space 3. The second telescopic element 7 is connected to a second telescopic rod 9 which is fixedly connected to the rigid mesh 5 on the right side of the airflow space 3. When the second telescopic rod 9 moves, it only drives the rigid mesh 5 on the right side of the airflow space 3. There are three of each of the first telescopic rods 8 and the second telescopic rod 9. The first telescopic rods 8 and the second telescopic rod 9 are arranged alternately. The corrugated plate 2 is provided with a sliding sleeve that cooperates with the first telescopic rods 8 and the second telescopic rod 9, which allows the first telescopic rods 8 and the second telescopic rod 9 to slide while ensuring sealing.

[0022] A spray pipe is installed on the inner top surface of the water flow space 4. The spray pipe 4 sprays cooling water onto the corrugated plates 2 on the left and right sides of the water flow space 4. A drainage trough 10 is installed on the inner bottom surface of the water flow space 4. The drainage trough 10 is connected to a water outlet pipe, which delivers hot water to other facilities that require hot water. Air vents 11 corresponding to the airflow space 3 are installed on the front and rear sides of the flow guide box 1. Sintering flue gas flows from front to back through the corresponding air vents 11 and through the airflow space 3.

[0023] The first telescopic element 3 and the second telescopic element 7 mentioned above are both electric telescopic rods. The working rod end of the electric telescopic rod is fixed with a crossbeam 12, and the first telescopic rod 8 and the second telescopic rod 9 are both fixed on the corresponding crossbeam 12.

[0024] To regularly clean the dust that falls onto the inner bottom surface of the airflow space 3 and prevent long-term accumulation, a spray pipe 13 is installed on the inner bottom surface of the airflow space 3. Multiple downward-facing air outlets 14 are evenly distributed along the axial direction on the spray pipe 13. A dust-blocking mechanism is installed inside the air outlet 14. The dust-blocking mechanism includes a central rod 15 fixed inside the air outlet 14 and two semi-circular wing plates 16 symmetrically hinged to the central rod 15. An overlapping ring edge 17 that cooperates with the wing plate 16 is also provided inside the air outlet 14. An elastic sheet 18 is provided on both wing plates 16. The elastic sheet 18 is a spring steel sheet, and its thickness is determined according to the weight of the wing plate 16. It is preferable that when the spray pipe 13 stops airflow, the elastic sheet 18 can drive the wing plate 16 to rise and approach the overlapping ring edge 17. Preferably, the wing plate 16 is made of cast iron. Permanent magnets are symmetrically arranged on the overlapping ring edge 17. The permanent magnets can help maintain the horizontal attitude of the wing plate 16. When the spray pipe 13 discharges airflow, it can push the wing plate 16 away from the permanent magnet.

[0025] The working principle of this embodiment is as follows:

[0026] Sintering flue gas passes through the airflow space 3 from front to back, and cooling water passes through the water flow space 4 from top to bottom. Heat exchange occurs between the gas and water walls, and the temperature of the sintering flue gas decreases. The first telescopic element 6 and the second telescopic element 7 are controlled by a timer switch or manually. When the first telescopic element 6 is activated, it causes the rigid mesh 5 on the left side of the airflow space 3 to detach from the corrugated plate 2, disrupting the continuity of the dust layer on the airflow space 3 side of the corrugated plate 2. Most of the dust clumps fall off. Similarly, when the second telescopic element 7 is activated, it causes the rigid mesh 5 on the right side of the airflow space 3 to detach from the corrugated plate 2, disrupting the continuity of the dust layer on the airflow space 3 side of the corrugated plate 2. Most of the dust clumps fall off, avoiding the reduction in heat conduction efficiency caused by long-term dust accumulation. After the operation is completed, the rigid mesh 5 reattaches to the corrugated plate 2, and the first telescopic element 6 and the second telescopic element 7 stop.

[0027] The spray pipe 13 is opened periodically, and the spray airflow pushes the wing plate 16 and blows it onto the inner bottom surface of the airflow space 3. The dust accumulated on the inner bottom surface of the airflow space 3 is lifted up and carried out of the airflow space 3 by the sintering flue gas, thus preventing the dust from accumulating on the inner bottom surface of the airflow space 3 for a long time. When the spray pipe 13 is closed, the wing plate 16 returns to horizontal and contacts the overlapping ring 17 under the action of the elastic sheet, and the air outlet 14 is sealed to prevent dust from entering the spray pipe 13 during daily operation.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
