Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas condensing heat exchanger technology, and in particular to a flue gas condensing heat exchanger with adjustable flow channel angle. Background Technology
[0002] A flue gas condensing heat exchanger is a highly efficient heat recovery device primarily used to capture and utilize waste heat from flue gas. By cooling the flue gas below its dew point, the water vapor it contains condenses into water droplets, releasing latent heat and further enhancing heat recovery efficiency. This process not only significantly improves the overall thermal efficiency of the system but also reduces the emission concentration of harmful gases (such as SOx and NOx) in the flue gas, which is of great significance for energy conservation, emission reduction, and environmental protection.
[0003] In existing flue gas condensing heat exchangers, the heat exchange tubes are mostly installed in a static and fixed manner inside the heat exchanger, and the airflow passes through the heat exchange tubes at a uniform angle. In order to promote stronger turbulence between the flue gas and the condensing tube wall, it is necessary to adjust the angle of the heat exchange tubes to accelerate the heat transfer speed and thus enhance the heat transfer efficiency. Therefore, a flue gas condensing heat exchanger with adjustable flow channel angle is proposed. Utility Model Content
