Technical Field

[0001] The utility model relates to the technical field of flue gas waste heat treatment, and particularly relates to an environment-friendly spliced multi-layer flue gas waste heat recovery device. Background Technique

[0002] Flue gas is a complex mixture generated during the high-temperature decomposition or combustion of substances. It mainly consists of solid and liquid particles, gases, and part of the air entrained and mixed in. Flue gas is often accompanied by high temperature during generation, and its temperature can reach hundreds or even thousands of degrees Celsius. High-temperature flue gas not only causes direct thermal damage to the human body but may also trigger fires or explosions.

[0003] In industrial production, flue gas is often directly discharged after treatment. The heat therein needs to be treated separately to avoid damage, thus wasting the heat energy therein. However, due to many impurities and pollutants in the flue gas, it cannot be directly used. For this reason, we propose an environment-friendly spliced multi-layer flue gas waste heat recovery device to solve the above problems. Content of the Utility Model
