Description

Technical Field

[0001] This utility model relates to the field of aluminum rod production technology, specifically a heating furnace for aluminum rod production. Background Technology

[0002] In the aluminum rod production process, the heating furnace is a key piece of equipment. If the flue gas generated during its operation is not properly treated, it will not only pollute the environment but also lead to heat waste and increased production costs. However, the flue gas treatment methods of heating furnaces used in aluminum rod production are often relatively simple, making it difficult to effectively remove harmful substances from the flue gas. At the same time, they lack full utilization of the waste heat from the flue gas, which does not meet the requirements of modern industrial energy conservation and environmental protection. Therefore, we propose a heating furnace for aluminum rod production. Utility Model Content

[0003] The purpose of this utility model is to provide a heating furnace for aluminum rod production, which has the advantages of good flue gas purification effect and waste heat recovery. It solves the problem that the flue gas treatment methods of current heating furnaces for aluminum rod production are often too simple, making it difficult to effectively remove harmful substances in the flue gas. At the same time, it lacks full utilization of the waste heat of the flue gas, which does not meet the requirements of modern industrial energy conservation and environmental protection.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a fan to introduce the flue gas generated by the heating furnace into the spray tank. The atomizing nozzle sprays liquid to spray the flue gas, which can effectively remove pollutants such as dust and harmful particles from the flue gas. Subsequently, the flue gas enters the filter tank through the inlet and is further filtered by the activated carbon filter to ensure that the emitted flue gas meets environmental protection standards and reduces pollution to the environment.

[0012] 2. This utility model uses a curved heat exchange tube to allow filtered flue gas to enter the second water tank and exchange heat with the water in the second water tank. This transfers the waste heat from the flue gas to the water in the second water tank, increasing the water temperature. This not only achieves the recovery and utilization of waste heat from the flue gas but also provides hot water for subsequent production or other uses, reducing energy consumption and saving production costs. The first liquid level sensor monitors the liquid level in the first water tank in real time, while the water temperature detector monitors the water temperature in the second water tank. The second liquid level sensor monitors the liquid level in the second water tank, and this data is transmitted to a display screen, allowing operators to monitor the equipment's operating status in real time.

A filter tank 21 is provided in the inner cavity of the housing 7, and an activated carbon filter screen 17 is provided in the inner cavity of the filter tank 21. An opening 16 is provided between the spray tank 15 and the filter tank 21. The top of the box 7 is fixedly connected to the first water tank 5 by a bracket. The top of the inner cavity of the first water tank 5 is fixedly connected to the first liquid level sensor 11. The bottom of the inner cavity of the first water tank 5 is fixedly connected to the pump 12. The outlet of the pump 12 is fixedly connected to the atomizing nozzle 13 through a pipe.

The air outlet of the fan 14 is fixedly connected to the left side of the inner cavity of the spray tank 15 through a pipe.

[0020] This technical solution uses a fan 14 to introduce the flue gas generated by the heating furnace body 2 into a spray tank 15. The atomizing nozzle 13 sprays liquid to treat the flue gas, which can effectively remove pollutants such as dust and harmful particles from the flue gas.

Example

[0021] Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, a second water tank 6 is fixedly connected to the right rear end of the top of the base plate 1. A curved heat exchange tube 18 is fixedly connected to the inner cavity of the second water tank 6 through a bracket. The outlet of the curved heat exchange tube 18 extends to the upper end of the top of the second water tank 6. The inlet of the curved heat exchange tube 18 is connected to the right end of the top of the inner cavity of the filter tank 21 through a pipe. A water temperature detector 19 is fixedly connected to the bottom of the inner cavity of the second water tank 6. A second liquid level sensor 20 is fixedly connected to the top of the inner cavity of the second water tank 6. An outlet 10 is opened at the bottom of the right side of the inner cavity of the second water tank 6. A valve is installed in the inner cavity of the outlet 10. Fixing blocks 3 are fixedly connected to the left and right ends of the front and rear sides of the base plate 1. Bolts 4 are provided on the fixing blocks 3. A PLC controller 8 and a display 9 are fixedly connected to the lower part of the back of the second water tank 6.

The input end of the display 9 is electrically connected to the output end of the first liquid level sensor 11, the water temperature detector 19 and the second liquid level sensor 20.

[0022] This technical solution uses curved heat exchange tubes 18 to allow filtered flue gas to enter the second water tank 6 and exchange heat with the water in the second water tank 6. This transfers the waste heat from the flue gas to the water in the second water tank 6, raising the water temperature. This not only achieves the recovery and utilization of waste heat from the flue gas but also provides hot water for subsequent production or other uses, reducing energy consumption and saving production costs. The first liquid level sensor 11 monitors the liquid level of the first water tank 5 in real time, the water temperature detector 19 monitors the water temperature of the second water tank 6, and the second liquid level sensor 20 monitors the liquid level of the second water tank 6. This data is transmitted to the display 9 for easy monitoring of the equipment's operating status by operators.

[0023] The working principle of this utility model is as follows: The flue gas generated by the heating furnace body 2 can be introduced into the spray tank 15 by the fan 14. The atomizing nozzle 13 sprays liquid to spray the flue gas, which can effectively remove dust, harmful particles and other pollutants in the flue gas. Then, the flue gas enters the filter tank 21 through the inlet 16 and is further filtered by the activated carbon filter 17 to ensure that the emitted flue gas meets environmental protection standards and reduces pollution to the environment. Through the curved heat exchange tube 18, the filtered flue gas can enter the second water tank 6 and exchange heat with the water in the second water tank 6, transferring the waste heat in the flue gas to the water in the second water tank 6 and increasing the water temperature. This not only realizes the recovery and utilization of waste heat from the flue gas, but also provides hot water for subsequent production or other uses, reducing energy consumption and saving production costs. The first liquid level sensor 11 monitors the liquid level of the first water tank 5 in real time, the water temperature detector 19 monitors the water temperature of the second water tank 6, and the second liquid level sensor 20 monitors the liquid level of the second water tank 6. These data are transmitted to the display 9 for display, so that the operator can keep track of the equipment's operating status in real time.
