Description

Technical Field

[0001] The utility model relates to the technical field of waste heat recovery, and in particular to a heat exchange system applied to an automobile parts production line. Background Art

[0002] The production process of aluminum alloy parts requires smelting, casting, heat treatment and machining. Among them, the smelting furnace used in the smelting process, the die-casting machine used in the casting process and the heat treatment furnace used in the heat treatment process will generate a lot of waste heat when working. At present, the waste heat generated during the operation of the above equipment is usually directly diffused and discharged, and is not effectively recycled. Equipment with thermal energy needs, such as machining equipment and factory heating equipment, often need to be heated separately through electricity, oil and gas energy, resulting in a huge waste of energy, which is not in line with the current energy-saving and environmentally friendly production concept.

[0003] Based on this, developing a heat exchange system for automotive parts production lines and applying it to actual production is an issue that needs to be solved urgently. Utility Model Content

[0004] The purpose of the utility model is to provide a heat exchange system for automobile parts production lines in order to solve the problem of lack of effective waste heat recovery measures in the current production process, resulting in large energy waste.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] Preferably, a dust collection port is provided at the bottom of the box body for recovering dust impurities entrained in the high-temperature flue gas.

[0010] Preferably, a recovery trolley is provided corresponding to the dust collection port to facilitate the recovery of dust impurities.

[0011] Preferably, a filter screen is provided on the air inlet for filtering larger impurities in the high-temperature flue gas entering the box.

[0012] Preferably, an inspection window is openably connected to the box wall of the box body, and the inspection window is made of transparent material.

[0013] The beneficial effect of the utility model is that the utility model realizes the effective recovery and utilization of high-temperature flue gas during the production process of aluminum alloy parts by arranging a heat exchange pipeline in a box body connected to the waste heat gas source, and uses the heat energy in the high-temperature flue gas as a heat source for heating normal temperature water, thereby eliminating the waste of heat energy. Normal temperature water does not need to be separately heated by electricity, oil and gas energy, and can meet the water temperature requirements of equipment preheating, factory heating and domestic water use, thereby achieving the purpose of energy saving and environmental protection; in the utility model, the heat exchange pipeline is arranged in a reciprocating folding shape, which increases the contact area between the high-temperature flue gas and the heat exchange pipeline and improves the heat exchange efficiency; a heat exchange fan is arranged in the box body, which accelerates the convection speed of the high-temperature flue gas in the box body, and further improves the heat exchange efficiency between the high-temperature flue gas and the heat exchange pipeline; at the same time, the heat exchange fan intensifies the turbulence of the high-temperature flue gas in the box body, ensures the uniformity of the high-temperature flue gas in the box body, thereby achieving the purpose of uniform and stable heating of the heat exchange pipeline; in addition, the heat exchange fan can also effectively reduce the dust accumulation on the heat exchange pipeline, further ensuring the heat exchange efficiency.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-3As shown, a heat exchange system used in an automobile parts production line includes a box 1, and the box 1 is connected with an air inlet 11 and an air outlet 12. The air inlet 11 is connected to the waste heat gas source, and the high-temperature flue gas with waste heat generated during the operation of equipment such as a smelting furnace and a heat treatment furnace is collected and input into the box 1. A heat exchange pipeline 2 connected to a water source is arranged in the box 1, and the heat exchange pipeline 2 is connected to a water inlet 21 and a water return port 22. When in use, the high-temperature flue gas collected by the waste heat gas source enters the box 1 through the air inlet 11, and at the same time, the normal temperature water supplied by the water source enters the heat exchange pipeline 2 in the box 1 through the water inlet 21. At this time, the high-temperature flue gas in the box 1 will exchange heat with the heat exchange pipeline 2 with normal temperature water, so that the normal temperature water in the heat exchange pipeline 2 is heated, and the low-temperature flue gas that has completed the heat exchange is discharged from the box 1 through the air outlet 12.

[0021] This implementation method realizes the effective recovery and utilization of high-temperature flue gas during the production process of aluminum alloy parts, and uses the heat energy in the high-temperature flue gas as a heat source for heating normal-temperature water, thereby avoiding waste of heat energy. Normal-temperature water does not need to be separately heated by electricity, oil and gas energy, and can meet the water temperature requirements of equipment preheating, factory heating and domestic water use, thereby achieving the purpose of energy saving and environmental protection.

[0022] As a preferred embodiment, Figure 3 As shown, the heat exchange pipeline 2 is arranged in a reciprocating folding structure to increase the contact area between the high-temperature flue gas and the heat exchange pipeline 2 and improve the heat exchange efficiency.

[0023] Furthermore, if Figure 2 As shown, a heat exchange fan 3 is provided in the box 1, and the heat exchange fan 3 is used to accelerate the convection speed of the high-temperature flue gas in the box 1, and improve the heat exchange efficiency between the high-temperature flue gas and the heat exchange pipeline 2. At the same time, the turbulence of the high-temperature flue gas in the box 1 is aggravated, and the uniformity of the high-temperature flue gas in the box 1 is improved, so as to achieve the purpose of uniform and stable temperature increase of the heat exchange pipeline 2. In addition, the heat exchange fan 3 can also effectively reduce the dust accumulation on the heat exchange pipeline 2, further ensuring the heat exchange efficiency.

[0024] Preferably, if Figure 2 As shown, a dust collection port 13 is provided at the bottom of the box 1 to recover dust impurities entrained in the high-temperature flue gas and reduce the effect of dust adhering to the heat exchange pipeline 2 on the heat exchange efficiency. Furthermore, a recovery trolley 4 is provided corresponding to the dust collection port 13 to facilitate the recovery of dust impurities.

[0025] Furthermore, if Figure 1-2 As shown, a filter screen 14 is provided on the air inlet 11 for filtering larger impurities in the high-temperature flue gas entering the box 1 to prevent the impurities from contaminating the heat exchange pipeline 2 and affecting the heat exchange efficiency.

[0026] Preferably, if Figure 1As shown, a maintenance window 15 is openably connected to the wall of the box body 1, and the maintenance window 15 is made of transparent material, which is convenient for operators to check the situation inside the box at any time and perform cleaning, inspection and maintenance operations in time.
