[0001] The utility model relates to the technical field of aging furnaces, in particular to a heat energy recovery matching component for aging furnaces. Background Art

[0002] Aging furnace, as an important equipment in the field of industrial heat treatment, plays a vital role in the processing and performance optimization of materials. It can accurately heat treat materials and improve the mechanical properties and stability of materials. It is widely used in many industries such as automobiles, aerospace, electricity, and construction.

[0003] The working principle of the aging furnace is to control the temperature and time in the furnace to heat treat the material under specific conditions. This treatment method can effectively eliminate the residual stress inside the material and improve the fatigue resistance and corrosion resistance of the material. At the same time, the aging furnace can also achieve grain refinement of the material through precise temperature control, further improving the strength and toughness of the material.

[0004] In the application process of aging furnace, although the heat treatment requirements of materials can be achieved, it is often accompanied by a large amount of heat energy loss. This lost heat energy not only causes energy waste, but also increases the operating costs of the enterprise, and it is impossible to effectively recover and utilize the heat energy generated by the aging furnace.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a heat recovery component for an aging furnace. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is a heat recovery supporting component for an aging furnace, which is provided with a recovery mechanism. The high-temperature flue gas generated when the aging furnace is in operation is sucked into the heat recovery box through the smoke exhaust fan and the smoke exhaust pipe at the bottom of the heat recovery box, and then forms an orderly flow in the flow cavity through the guiding effect of multiple groups of guide plates, thereby increasing the residence time of the flue gas in the heat recovery box and improving the heat recovery efficiency.

DETAILED DESCRIPTION

[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution for a heat recovery component for an aging furnace: it includes a furnace body 1, a furnace door mechanism 2 is provided at the furnace mouth of the furnace body 1, a recovery mechanism 3 is provided on the top of the furnace body 1, the recovery mechanism 3 includes a heat recovery box 31, the wall of the heat recovery box 31 is filled with a heat preservation material 38, a smoking fan 33 is installed on the outer wall of the bottom of the heat recovery box 31, the input end of the smoking fan 33 is connected to a smoking pipe 34, the smoking pipe 34 is connected to the furnace body 1, the output end of the smoking fan 33 is connected to a smoke exhaust pipe 35, the smoke exhaust pipe 35 is connected to the heat recovery box 31, the heat recovery box 31 is connected to the furnace body 1, and a plurality of guide plates 36 are provided in the heat recovery box 31, and adjacent guide plates 36 and the heat recovery box 31 are separated by flow The moving cavity 37, multiple groups of guide plates 36 are distributed in parallel, and one end is connected to the inner wall of the heat recovery box 31, and the other end leaves a gap with the inner wall for guiding the flow of high-temperature flue gas. A discharge port 32 is installed on the top of the heat recovery box 31. Multiple groups of main heat exchange pipes 39 are arranged in the heat recovery box 31. Each group of main heat exchange pipes 39 is connected to an auxiliary heat exchange pipe 40. Multiple groups of main heat exchange pipes 39 and auxiliary heat exchange pipes 40 are arranged in an L-shape, and the wall length of the main heat exchange pipe 39 is greater than the wall length of the auxiliary heat exchange pipe 40. Specifically, the main heat exchange pipe 39 is connected to the heat exchange medium through the lower interface, and flows along the auxiliary heat exchange pipe 40 and the main heat exchange pipe 39 respectively, and finally merges into the upper interface of the main heat exchange pipe 39 for discharge, so as to realize the heat recovery of the high-temperature flue gas.

[0021] In this embodiment, when the aging furnace is in use, after the smoke exhaust fan 33 is started, the high-temperature flue gas in the furnace body 1 is sucked into the heat recovery box 31 through the smoke exhaust pipe 34. The high-temperature flue gas passes through the guiding effect of multiple groups of guide plates 36 in the heat recovery box 31, and forms an orderly flow in the flow cavity 37, which increases the residence time of the flue gas in the heat recovery box 31 and improves the heat recovery efficiency. At the same time, the flue gas exchanges heat with the main heat exchange pipe 39 and the auxiliary heat exchange pipe 40 in the heat recovery box 31 during the flow process, transfers the heat energy to the medium in the heat exchange pipe, and realizes the recovery and utilization of heat energy. The setting of the thermal insulation material 38 can effectively reduce the heat loss of the heat recovery box 31 and improve the heat recovery efficiency. Finally, the flue gas after the heat recovery treatment is discharged through the exhaust port 32, realizing the recovery and utilization of the heat energy generated when the aging furnace is running, improving the energy utilization efficiency and reducing the operating costs of the enterprise.

[0022] In addition, since the wall length of the main heat exchange tube 39 is greater than that of the auxiliary heat exchange tube 40, the contact area between the medium in the main heat exchange tube 39 and the high-temperature flue gas is larger, and the heat exchange efficiency is higher. At the same time, the setting of the auxiliary heat exchange tube 40 can increase the heat exchange area and further improve the heat recovery efficiency. By adjusting the number and layout of the main heat exchange tube 39 and the auxiliary heat exchange tube 40, it can adapt to aging furnaces of different sizes and meet different production needs.

[0023] The utility model provides a heat energy recovery supporting component for an aging furnace, which has a simple structure and is easy to operate. It can realize the recovery and utilization of heat energy generated when the aging furnace is running, thereby improving energy utilization efficiency, reducing enterprise operating costs, and has broad application prospects.

[0024] Working principle and use process of the utility model: By setting up a recovery mechanism, the heat energy recovery of high-temperature flue gas is realized. Specifically, when the smoke exhaust fan 33 is started, it will suck the high-temperature flue gas in the furnace body 1 into the heat energy recovery box 31 through the smoke exhaust pipe 34. These high-temperature flue gases are guided by the guide plate 36 in the heat energy recovery box 31 to form an orderly flow, thereby increasing the residence time of the flue gas in the box and improving the efficiency of heat energy recovery.

[0025] During the flow of flue gas, it will exchange heat with the main heat exchange tube 39 and the auxiliary heat exchange tube 40 in the heat recovery box 33. Heat exchange medium flows inside these heat exchange tubes. When the high-temperature flue gas contacts the heat exchange tubes, heat is transferred to the medium, thereby realizing heat recovery. Since the wall length of the main heat exchange tube 40 is greater than that of the auxiliary heat exchange tube 39, the medium in the main heat exchange tube has a larger contact area with the high-temperature flue gas, thereby improving the efficiency of heat exchange.

[0026] In addition, the insulation material in the heat recovery box can effectively reduce heat loss and further improve the efficiency of heat recovery. The flue gas after heat recovery treatment will have a greatly reduced temperature and then be discharged through the exhaust port, which not only meets environmental protection requirements but also realizes the effective use of energy.
