Description

Technical Field

[0001] This invention relates to the field of hot flue gas treatment technology, and in particular to an energy-saving hot flue gas treatment device for industrial furnaces. Background Technology

[0002] Energy-saving industrial furnace hot flue gas treatment device is a device specifically designed to treat the hot flue gas generated by industrial furnaces. It aims to improve energy utilization efficiency, reduce pollutant emissions, and lower production costs. Since the temperature of the flue gas discharged from the industrial furnace is relatively high, the device can achieve energy savings of 15% to 25% by recovering the waste heat from the flue gas.

[0003] To better recover heat from flue gas, it is usually necessary to recover the heat from the freshly discharged hot flue gas in order to reduce the efficiency of heat recovery. However, the freshly discharged hot flue gas contains a large amount of particulate matter. A large amount of particulate matter adheres to the inner wall of the flue gas channel, which will affect the recovery of residual heat in the flue gas and may also cause blockage of the flue gas channel, thus affecting the effect of flue gas treatment.

[0033] Reference Figures 1-10 This invention proposes an energy-saving industrial furnace hot flue gas treatment device, including a treatment box 1, which is an insulated box body. The treatment box 1 has a treatment cavity inside. An air inlet pipe 2 connected to the treatment cavity is installed on the top of the treatment box 1, and an air outlet pipe 3 connected to the treatment cavity is installed on the bottom of the treatment box 1. When hot flue gas is discharged from the industrial furnace, the hot flue gas is injected into the treatment box 1 through the air inlet pipe 2. The hot flue gas is treated in the treatment box 1 and then discharged through the air outlet pipe 3. The discharged flue gas is then subjected to subsequent purification treatment.

[0034] like Figure 2 , Figure 3 and Figure 4As shown, an exchange box 4 is fixedly installed inside the processing chamber of the processing box 1. The exchange box 4 can divide the processing chamber into an air inlet chamber and a filter chamber arranged vertically. The exchange box 4 is located between the air inlet chamber and the filter chamber. A heat exchange chamber is opened inside the exchange box 4. A heat exchange tube 7 slides through the exchange box 4. The two ends of the heat exchange tube 7 are respectively connected to the air inlet chamber and the filter chamber. A partition is slidably installed inside the exchange box 4. The partition can divide the heat exchange chamber inside the exchange box 4 into a pressure regulating chamber and a displacement chamber arranged vertically. An exhaust pipe is installed in the pressure regulating chamber to discharge gas, thereby ensuring the pressure regulating chamber is properly positioned. The pressure inside the pressure chamber ensures the sliding of the partition. One side of the treatment box 1 is equipped with an inlet pipe 5 communicating with the replacement chamber, and the other side is equipped with an outlet pipe 6 communicating with the replacement chamber. The heat exchange tube 7 passes through the partition, which allows the heat exchange tube 7 to slide within the heat exchange chamber. A guide structure is installed on the exchange box 4. When the heat exchange tube 7 rises and falls within the exchange box 4, the guide structure guides the heat exchange tube 7 to rotate spirally. During heat recovery, assuming the temperature of the hot flue gas rises, the hot flue gas is introduced into the treatment box 1, and then passes through the heat exchange tube 7, simultaneously... Water is injected into the displacement chamber of the heat exchanger 4 through the inlet pipe 5. The heat from the flue gas in the heat exchange tube 7 exchanges heat with the water in the placement chamber, heating the water. In practice, the temperature of the flue gas discharged from the industrial furnace may also change, which can increase the flow rate of water entering the displacement chamber through the inlet pipe 5 and control the flow rate of water exiting through the outlet pipe 6, thus increasing the water pressure in the displacement chamber. After the water pressure increases, the water will exert pressure on the separator, causing the separator to slide within the heat exchanger, increasing the space of the displacement chamber and the length of the heat exchange tube 7 within the displacement chamber. The increased heat exchange contact area allows for greater volume of water to exchange heat, improving heat exchange efficiency and reducing heat loss due to unexchanged heat in the flue gas. The volume of the replacement chamber can be adjusted according to actual conditions to ensure heat exchange efficiency. During the lifting and lowering motion of the heat exchange tube 7, the tube rotates in a spiral motion, altering the flow of flue gas within the tube 7 to reduce the scouring effect on the inner wall of the tube. This reduces particulate matter adhesion, ensuring unobstructed flow within the tube and minimizing flue gas blockage.

[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the heat exchange box 4 is equipped with a striking mechanism. When the separator moves up and down inside the heat exchange box 4, it can drive the striking mechanism to strike the outer periphery of the heat exchange tube 7. After long-term use, some particulate matter will adhere to the inner wall of the heat exchange tube 7. The striking mechanism can strike the outer periphery of the heat exchange tube 7 to make the heat exchange tube 7 vibrate. The vibration will shake off the adhered matter on the inner wall of the heat exchange tube 7, which can clean the heat exchange tube 7 and reduce the clogging of the heat exchange tube 7.

[0036] like Figure 2 As shown, a filter structure is installed inside the filter chamber, and an anti-clogging cleaning structure is also installed inside the filter chamber. The anti-clogging cleaning structure is used to clean the adhering substances on the filter structure. In order to better recover the heat in the flue gas discharged from the industrial furnace, heat recovery is usually performed on the flue gas that has just been discharged from the industrial furnace. Therefore, the discharged flue gas contains a large number of particulate matter. In order to treat the flue gas, it needs to be filtered and then purified. The filter structure filters the particulate matter in the flue gas, and the anti-clogging cleaning structure cleans the filter structure to reduce the occurrence of blockage and ensure the smooth delivery of flue gas.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the separator includes a heat-insulating float 8; the density of the heat-insulating float 8 is less than that of water, so that after the water enters the replacement chamber, it can better drive the heat-insulating float 8 to slide in the heat exchange chamber. The heat-insulating float 8 is slidably installed in the heat exchange chamber. A reset assembly is installed in the exchange box 4. The reset assembly is used to drive the heat-insulating float 8 to slide and reset in the heat exchange chamber. The reset assembly controls the sliding reset of the heat-insulating float 8.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the reset assembly includes a connecting pipe 9, a limiting plate 10, and a reset spring 11. The top of the exchange box 4 has an air inlet communicating with the pressure regulating chamber. The connecting pipe 9 is fixedly installed in the air inlet. The top end of the heat exchange tube 7 is slidably inserted into the connecting pipe 9. The outer diameter of the heat exchange tube 7 is the same as the inner diameter of the connecting pipe 9. The limiting plate 10 is fitted around the outer periphery of the connecting pipe 9. The reset spring 11 is fitted around the outer periphery of the heat exchange tube 7, and both ends of the reset spring 11 abut against the limiting plate 10 and the heat insulation float 8, respectively. When the heat insulation float 8 slides, the compression state of the reset spring 11 will also change accordingly. The rebound action of the reset spring 11 drives the heat insulation float 8 to slide and reset. In addition, when the heat exchange tube 7 slides with the heat insulation float 8, the heat exchange tube 7 can scrape off the inner wall of the connecting pipe 9, thereby ensuring the cleanliness of the inner wall of the connecting pipe 9.

[0039] like Figure 3 , Figure 4 and Figure 7As shown, the guiding structure includes a guide tube 12 and a sliding shaft 13; the bottom of the heat exchange box 4 is provided with an air outlet communicating with the replacement chamber, the guide tube 12 is fixedly installed in the air outlet, the bottom end of the heat exchange tube 7 is slidably inserted into the guide tube 12, the outer diameter of the heat exchange tube 7 is the same as the inner diameter of the guide tube 12, the sliding shaft 13 is fixedly connected to the outer circumference of the heat exchange tube 7, and the inner wall of the guide tube 12 is provided with a spiral groove that slides and engages with the sliding shaft 13. When the heat exchange tube 7 slides up and down, the heat exchange tube 7 will drive the sliding shaft 13 to move up and down synchronously, and the sliding shaft 13 will slide along the spiral groove, so that the sliding shaft 13 makes a spiral rotation up and down movement, so that the heat exchange tube 7 makes a spiral rotation up and down movement synchronously.

[0040] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the striking mechanism includes a side frame 14, an end face gear 15, a striking block 16, and a drive assembly. The side frame 14 is fixedly installed inside the exchange box 4. A movable slot is provided on the side frame 14. The end face gear 15 is rotatably installed in the movable slot. The striking block 16 is installed on the outer periphery of the end face gear 15. The drive assembly is used to drive the end face gear 15 to rotate in the movable slot. When the end face gear 15 rotates, it can drive the striking block 16 to rotate and cause the striking block 16 to strike the outer periphery of the heat exchange tube 7. During heat exchange and heat recovery, the drive assembly drives the end face gear 15 to rotate. The rotation of the end face gear 15 will drive the striking block 16 to make a circular motion, so that the striking block 16 strikes the outer periphery of the heat exchange tube 7, causing the heat exchange tube 7 to vibrate. The vibration of the heat exchange tube 7 shakes off the dirt adhering to the inner wall of the heat exchange tube 7, which plays a certain role in cleaning the inner wall of the heat exchange tube 7.

[0041] like Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10As shown, the drive assembly includes a transmission gear 17, a drive gear 18, and a drive rack 19. The transmission gear 17 is rotatably mounted inside the side frame 14 and meshes with the end face gear 15. The drive gear 18 is rotatably mounted inside the side frame 14. One end of the drive rack 19 is fixedly connected to the heat-insulating float 8. The drive rack 19 slides through the side frame 14 and meshes with the drive gear 18. When the heat-insulating float 8 moves up and down under the pressure of the water and the rebound action of the return spring 11, the heat-insulating float 8 will drive the drive rack. 19 moves up and down synchronously. When the drive rack 19 moves up and down, the drive rack 19 will drive the drive gear 18 to rotate. When the drive gear 18 rotates, the drive gear 18 meshes with the transmission gear 17 and drives the transmission gear 17 to rotate. The drive gear 18 will drive the transmission gear 17 to rotate. The transmission gear 17 will drive the end face gear 15 to rotate. The end face gear 15 will drive the striking block 16 to rotate synchronously. When the striking block 16 rotates, it will strike the outer periphery of the heat exchange tube 7, causing the heat exchange tube 7 to vibrate and shake off the adhering material on its inner wall.

[0042] In practice, when the striking block 16 strikes the outer circumference of the heat exchange tube 7, the drive rack 19 will continue to move. The striking block 16 may press against the outer circumference of the heat exchange tube 7 and be unable to continue rotating, thus affecting the continued movement of the drive rack 19. At the same time, when the striking block 16 rotates slowly, the striking force is small, which will affect the vibration effect. Therefore, the following design is adopted.

[0043] like Figure 5 and Figure 6 As shown, the drive assembly also includes a spring 20; the drive gear 18 has multiple teeth on the side near the transmission gear 17, the teeth are arranged in an arc shape and mesh with the transmission gear 17; the end gear 15 is rotatably mounted in the side frame 14 via a rotating shaft, the side frame 14 has a rotating groove, a portion of the end gear 15's rotating shaft is located in the rotating groove, the outer ring end of the spring 20 is fixedly connected to the inner wall of the rotating groove, and the inner ring end of the spring 20 is fixedly connected to the rotating shaft of the end gear 15; an elastic rod 21 is connected between the end gear 15 and the striking block 16, the elastic rod 21 is designed to bend when the striking block 16 needs to pass over the heat exchange tube 7, ensuring that the striking block 16 passes over the heat exchange tube 7, and the teeth on the side of the drive gear 18 are distributed as follows when the drive gear 18 rotates. Figure 9As shown in the diagram, the drive gear 18 will only drive the transmission gear 17 to rotate when the side teeth of the drive gear 18 mesh with the transmission gear 17. (This allows the transmission gear 17 to rotate at a certain angle, which in turn drives the end face gear 15 to rotate at a certain angle, and the end face gear 15 drives the striking block 16 to rotate at the same angle.) Combined with the torque force of the spring 20, the end face gear 15 is driven to rotate. The end face gear 15 will drive the elastic rod 21 and the striking block 16 to rotate synchronously. (Due to the characteristics of the spring 20, the rotational force of the spring 20 driving the end face gear 15 remains constant, regardless of the torsional state of the spring 20.) This causes the striking block 16 to strike the outer circumference of the heat exchange tube 7 rapidly, causing the heat exchange tube 7 to vibrate and ensuring the striking vibration effect.

[0044] like Figure 2 As shown, the filter structure includes a mounting plate 22 and a mesh filter cartridge 23. The mounting plate 22 is fixedly installed in the filter chamber, and an air passage is opened through the mounting plate 22. The mesh filter cartridge 23 is installed in the air passage. The mesh filter cartridge 23 is a conical bag filter cartridge, and the flue gas is filtered by the mesh filter cartridge 23.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 10 As shown, the anti-clogging cleaning structure includes a mounting rod 24, an elastic rod 25, and a lever 26. The mounting rod 24 is fixedly connected to the bottom surface of the exchange box 4. One end of the elastic rod 25 is fixedly connected to the mounting rod 24. The middle part of the mesh filter cartridge 23 is suspended on the elastic rod 25. The lever 26 is fixedly connected to the bottom end of the drive rack 19. The lever 26 can move the elastic rod 25. When the heat insulation float 8 moves up and down, the heat insulation float 8 will drive the drive rack 18 to move up and down synchronously. The drive rack 18 will drive the lever 26. 6. Synchronous lifting and lowering movement: When the lever 26 moves up and down, the lever 26 will abut against the end of the elastic rod 25. The lever 26 will bend against the elastic rod 25 until the lever 26 passes the elastic rod 25. The elastic rod 25 is no longer pushed by the lever 26, and the elastic rod 25 returns to its deformation and vibrates. At the same time as the elastic rod 25 vibrates, it will also drive the mesh filter cartridge 23 to vibrate, shaking off dust and other particles on the mesh filter cartridge 23, ensuring the cleanliness of the mesh filter cartridge 23 and ensuring the smooth flow of flue gas.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
