Technical Field

[0001] The utility model relates to the technical field of plate-carrying glass kilns, in particular to a heat recovery and utilization device for a chimney of a plate-carrying glass kiln. Background Art

[0002] During the processing of plate glass, the kiln heats the material to about 1400℃, and the temperature of the smoke in the smoke exhaust system is about 300℃. The long-term emission of high-temperature smoke causes the iron chimney to age, oxidize, and eventually break. Replacing the chimney requires shutting down the machine and production. Therefore, a Chinese utility model patent with patent number CN221254414U appeared. The patent discloses a cooling flue for connecting to a furnace head. The cooling flue includes a first flue, a second flue and a cooling water tray. The first flue is used to discharge smoke, and the second flue is sleeved on the outside of the first flue, and the end face between the first flue and the second flue is sealed. The cooling water coil is a normally open cooling water coil, which is wound around the first flue, and the second flue is abutted against the cooling water coil. The cooling water coil extends along the length direction of the first flue or the second flue.

[0003] There are at least the following problems in the above patent: first, the cooling water coil is wound around the first flue, which is troublesome to install and even more inconvenient to disassemble and maintain later; second, the heat absorbed by the cooling water pan cannot be effectively utilized, resulting in energy waste.

[0021] By setting up the kiln chimney 1, the flue gas in the kiln can be discharged; by setting up the water tank 3, cold water can be stored and heat exchanged with the kiln chimney 1, which can not only reduce the temperature of the kiln chimney 1 and the high-temperature flue gas, but also recover heat to heat cold water for use by the staff in the factory; by setting up the first serpentine heat exchange tube 2, the first water pipe 5, the second water pipe 6 and the second serpentine heat exchange tube 4, a complete heat exchange pipeline can be formed. The first serpentine heat exchange tube 2 can exchange heat with the kiln chimney 1 and absorb the heat of the high-temperature flue gas. The second serpentine heat exchange tube 4 can exchange heat with the cold water in the water tank 3 and heat the cold water in the water tank 3. The side surface of the first serpentine heat exchange tube 2 cooperates with the outer wall of the kiln chimney 1, so the first serpentine heat exchange tube 2 can be conveniently installed on the outer wall of the kiln chimney 1, and it is also convenient to remove and replace it from the outer wall of the kiln chimney 1, or to inspect and repair the kiln chimney 1.

[0022] like Figures 1 to 2 As shown, the length of the arc of the first serpentine heat exchange tube 2 is less than or equal to half the circumference of the furnace chimney 1. To ensure the convenience of disassembly and installation of the first serpentine heat exchange tube 2, the first serpentine heat exchange tube 2 can be installed from both sides of the furnace chimney 1, without having to insert it from the end of the furnace chimney 1.

[0023] like Figure 1 As shown, the edges of two adjacent groups of first serpentine heat exchange tubes 2 abut against each other, thereby ensuring the heat exchange area between the first serpentine heat exchange tubes 2 and the kiln chimney 1 and improving the heat exchange efficiency.

[0024] The top end of the first serpentine heat exchange tube 2 is detachably connected to the first water pipe 5 via a joint, and the bottom end of the first serpentine heat exchange tube 2 is detachably connected to the second water pipe 6 via a joint. This allows for easy disassembly and assembly of the first serpentine heat exchange tube 2, making it easy to replace it if damaged.

[0025] like Figure 1As shown, the first water pipe 5 is provided with an exhaust pipe 7, the top of which is provided with an exhaust valve 8. The exhaust pipe 7 is provided with a water supply pipe 9, which is provided with a valve. The second water pipe 6 is provided with a first pipeline pump 10. The exhaust pipe 7 and the exhaust valve 8 enable the gas in the heat exchange pipeline to be discharged; the water supply pipe 9 enables the heat exchange pipeline to be replenished with fluid; and the first pipeline pump 10 enables the heat exchange medium in the heat exchange pipeline to circulate, thereby performing heat exchange.

[0026] like Figure 1 As shown, a water inlet pipe 11 is provided at the top of the water storage tank 3, a water outlet pipe 12 is provided at the bottom of the water storage tank 3, a second pipeline pump 13 is provided on the water outlet pipe 12, and valves are provided on both the water inlet pipe 11 and the water outlet pipe 12. The water inlet pipe 11 can be used to fill the water storage tank 3 with water; the water outlet pipe 12 and the second pipeline pump 13 can be used to drain the water in the water storage tank 3 for use.

[0027] like Figure 1 As shown, the water tank 3 is provided with a liquid level sensor 14 and a temperature sensor 15. By providing the liquid level sensor 14, the water level in the water tank 3 can be detected, so that water can be injected when the water level is low and water injection can be stopped when the water level is high; by providing the temperature sensor 15, the water temperature in the water tank 3 can be detected.

[0028] like Figure 1 As shown, a protective sleeve 16 is provided on the outside of the first serpentine heat exchange tube 2. The protective sleeve 16 includes several sets of mounting plates, with two adjacent sets of mounting plates connected to each other by bolts. The provision of the protective sleeve 16 and mounting plates can protect the first serpentine heat exchange tube 2 and facilitate disassembly and assembly.

[0029] During installation, the staff can fit and fix the first serpentine heat exchange tube 2 to the kiln chimney 1 from both sides of the kiln chimney 1, and then connect the first serpentine heat exchange tube 2 with the first water pipe 5 and the second water pipe 6 through the joint, and finally install the installation piece to the outside of the first serpentine heat exchange tube 2, and connect the first serpentine heat exchange tube 2 to each other to form a protective sleeve 16 through bolts; during the heat exchange process, the high-temperature flue gas in the kiln chimney 1 is discharged from bottom to top, and the heat exchange medium in the heat exchange pipeline flows in from the top of the first serpentine heat exchange tube 2 and flows out from the bottom of the first serpentine heat exchange tube 2, which can maximize the absorption of the heat of the high-temperature flue gas in the kiln chimney 1; after absorbing the heat of the high-temperature flue gas, the heat exchange medium flows in from the bottom end of the second serpentine heat exchange tube 4 and flows out from the top end of the second serpentine heat exchange tube 4, which can maximize the absorption of the heat of the high-temperature flue gas The heat is exchanged with the cold water in the water storage tank 3 at a high degree. In actual use, the water storage tank 3 can be provided with multiple groups to ensure continuous heat exchange with the kiln chimney 1, and valves are provided at the connection between the second serpentine heat exchange tube 4 and the first water pipe 5 and the second water pipe 6. When the temperature sensor 15 detects that the water temperature in the water storage tank 3 has risen to a certain temperature, the valve on the second serpentine heat exchange tube 4 of the water storage tank 3 can be closed, and the valve on the second serpentine heat exchange tube 4 of another group of water storage tanks 3 can be opened to continue heat exchange with the kiln chimney 1. The factory staff can use the hot water in the heated water storage tank 3. When the liquid level sensor 14 detects that the water level in the water storage tank 3 has dropped to the lowest water level, the valve on the water inlet pipe 11 of the water storage tank 3 can be opened to fill the water storage tank 3 with water and wait for heat exchange to rise. The utility model is convenient for disassembly and assembly, reducing the difficulty of installation and maintenance personnel, and can also utilize the heat in the high-temperature flue gas, effectively extending the service life of the chimney and improving energy utilization.
