[0002] In the operation process of the high-temperature reaction furnace, a large amount of high-temperature flue gas or high-temperature gas will be generated. If it is directly discharged, not only the energy will be wasted, but also the heat pollution to the environment will be caused. Therefore, the recovery and utilization of the waste heat in the high-temperature gas has become one of the important means of industrial energy saving and consumption reduction. At present, the common waste heat recovery device mostly adopts the fixed heat exchange pipe structure, and the heat exchange is realized by the indirect contact between the cooling water and the high-temperature gas. However, such device generally has the problems of low heat exchange efficiency, easy dust accumulation and difficult maintenance.

[0003] On the one hand, the contact area between the fixed heat exchange pipe and the gas is limited, and the water flow speed is slow, which leads to insufficient heat exchange.
