[0001] This utility model relates to the field of annealing furnace technology, specifically to an annealing furnace with good waste gas treatment effect. Background Technology
[0002] Annealing furnaces are a metal heat treatment process in which metal parts are placed in different annealing furnaces and slowly heated to a certain temperature, held at that temperature for a period of time, and then cooled at a suitable rate (usually natural cooling, sometimes controlled cooling). The purpose is to soften materials or workpieces that have been cast, forged, welded, or machined, reduce their hardness, and improve their plasticity and toughness.
[0003] Patent document CN221522705U discloses an annealing furnace with low-cost smoke purification function. "In this patent document, the smoke dust in the annealing furnace flue gas is absorbed by bubbles, which effectively prevents the smoke dust from damaging the filter element, ensures the service life of the filter element, and reduces the cost of flue gas treatment. However, when treating the waste gas, this annealing furnace cannot effectively utilize the heat in the waste gas first, so the annealing furnace lacks energy-saving and environmental protection effects.

[0023] The annealing furnace body 1 includes a heat transfer assembly. The heat transfer assembly is installed on the top of the annealing furnace body 1. The heat transfer assembly is used to transfer and utilize the heat in the exhaust gas. The heat transfer assembly includes a mounting shell 8, an exhaust gas passage 9, and a liquid pipe 10. The mounting shell 8 is installed on the top of the annealing furnace body 1. The exhaust gas passage 9 is installed around the inside of the mounting shell 8. The liquid pipe 10 is installed inside the exhaust gas passage 9. An inlet 11 connected to one end of the liquid pipe 10 is installed on one side of the mounting shell 8. An outlet 12 connected to the other end of the liquid pipe 10 is installed on the other side of the mounting shell 8. A transmission pipe 6 is installed through the top of the annealing furnace body 1. One end of the transmission pipe 6 is connected to the mounting shell 8. A control valve 7 is installed on the outside of the transmission pipe 6. A connecting pipe 13 is installed through the back of the mounting shell 8. One end of the connecting pipe 13 is connected to the exhaust gas passage 9.
[0024] The annealing furnace body 1 is used to anneal workpieces. During the annealing process, high-heat exhaust gas is generated. The exhaust gas needs to be purified before it can be discharged to the outside. However, the exhaust gas carries heat. In order to make full use of the heat it carries, a heat transfer component is installed to transfer the heat in the exhaust gas. By opening the control valve 7, the exhaust gas can enter the heat transfer component through the transmission pipe 6. The exhaust gas containing heat enters the interior of the exhaust gas channel 9. The liquid for heat transfer enters the interior of the liquid pipe 10 through the inlet 11. Since the liquid pipe 10 is located inside the exhaust gas channel 9, the entering liquid can be heated by the heat of the exhaust gas, so that the annealing furnace has the function of energy saving and environmental protection. At the same time, the temperature in the exhaust gas will also be reduced, avoiding the impact of excessive heat in the exhaust gas on the purification component.

An adsorption pad 18 is installed inside the purification shell 14 through the mounting bracket 17. The adsorption pad 18 is used to purify the exhaust gas. After purification, it is discharged through the exhaust pipe 15. Since the adsorption pad 18 is installed inside the mounting bracket 17, the mounting bracket 17 is connected to the positioning groove 16 through the fixing block 20, so that the mounting bracket 17 can be disassembled to facilitate the replacement of the adsorption pad 18.
[0028] Working principle: Before using an annealing furnace with good exhaust gas treatment effect, check whether there are any problems that may affect its use. First, support the annealing furnace in the required position using the support leg 2, pull out the sliding table 4, place the workpiece to be annealed on the sliding table 4, and then push it into the heating chamber 3. Close the sealing door 5 to perform annealing treatment on the workpiece.

After purification, the exhaust gas is discharged through the exhaust pipe 15.
