Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery and reuse device. Background Technology

[0002] In many scenarios such as industrial production, energy conversion and daily life, a large amount of airflow containing waste heat is generated. If this waste heat is directly discharged, it will not only cause serious energy waste, but may also cause thermal pollution to the environment, which does not meet the current requirements of energy conservation, emission reduction and sustainable development. Therefore, the recycling and reuse of waste heat has important practical significance.

[0003] For example, taking Chinese utility model patent CN215638984U as an example, the waste heat recovery and utilization device for methyl acetal production disclosed therein has a problem when recovering heat energy from wastewater. Because the cold water pipe is wrapped around the treatment frame, the heat in the middle area of ​​the treatment frame must first be conducted to the side wall and then transferred to the cold water pipe. The heat conduction path is long and relatively thick, which is not conducive to the heat conduction in the middle area and seriously affects the waste heat recovery effect. Another example is the waste heat recovery device for cooling towers disclosed in CN218723280U, which requires the connection of multiple water pumps during use. This not only greatly increases the manufacturing cost and power consumption of the device, but also makes the external pipeline water circuit extremely complex, and the installation and connection operation difficult, which greatly reduces the practicality of the device. Therefore, it is necessary to design a waste heat recovery and utilization device to solve the above problems. Utility Model Content
