Abstract

The present invention discloses a heat recovery device comprising an outer frame, at least a first tube body and at least one second pipe body. The outer frame has a hot penetration side and a containment space. The first tube body is provided in the accommodating space. The first body comprises a first material. The second body is disposed in the containment space. The second tube is away from the heat-through side of the first tube and is axially spaced from the first tube. The second body comprises a second material. The heat resistance temperature of the first material is greater than the heat resistance temperature of the second material. The heat transfer coefficient of the second material is greater than the thermal conductivity of the first material. In the thermal energy recovery apparatus of the present invention, it is possible to prevent the high-intensity radiant heat from causing the first tube to be deformed by the first tube body having a high heat-resistant temperature being disposed closer to the heat-through side, Intensity of radiant heat, the lower intensity of radiant heat can be further absorbed by the second tube with higher heat transfer capability, but can improve the overall radiation heat absorption efficiency.

Description

technical field

[0001] The present invention relates to a heat recovery device, in particular to a heat recovery device that absorbs radiant heat. Background technique

[0002] Since the Industrial Revolution, people have often obtained energy through combustion to manufacture other products. However, in industrial combustion equipment, in addition to the directly obtained energy, a lot of radiant heat is still generated. At present, the five major domestic industrial radiant heat are metal smelters, glass panel factories, cement plants, petrochemical plants and paper mills. Since the process operation is usually carried out at a temperature of several hundred degrees Celsius to thousands of degrees Celsius, the unused heat energy is mostly dissipated in the environment in the form of heat radiation.

[0003] However, traditionally, there is no corresponding recovery mechanism, so these radiant heat is regarded as waste heat that cannot be recovered and reused. For exampl...
