Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a novel flue gas waste heat recovery heat exchanger. Background Technology

[0002] Chemical production processes generate large amounts of high-temperature flue gas. Flue gas waste heat recovery heat exchangers are devices used in industrial production processes to recover and utilize the energy from the generated high-temperature flue gas. They utilize the high-temperature flue gas to exchange heat with low-temperature media (such as water or air) to improve energy efficiency and reduce pollution emissions.

[0003] Regarding the aforementioned technologies, the existing heat exchangers have the following drawbacks: the contact efficiency between the flue gas introduced into the existing heat exchangers and the clean water that needs to be heated is not high enough. The flue gas can only freely spread into the heat exchanger and exchange heat with the clean water in the water pipe, resulting in a slow heating speed for the clean water. Therefore, this utility model provides a novel flue gas waste heat recovery heat exchanger. Utility Model Content
