Description

Technical Field

[0001] This utility model belongs to the field of steam heat exchange technology, and specifically relates to a steam heat exchange secondary utilization device. Background Technology

[0002] Steam heat exchange is a process that uses steam as a heat medium to exchange heat energy. It utilizes the latent heat and exhaust heat of steam to transfer heat to other fluids, such as water or air, through heat exchange equipment. Waste heat recovery involves recovering waste heat from industrial production through heat exchangers, achieving secondary energy utilization and reducing energy waste. Since steam may contain minerals, chemicals, and fine solid dust particles from the water, these impurities, if introduced directly into the waste heat recovery equipment without filtration, can lead to corrosion and damage. However, steam heat exchange secondary utilization devices that do not clean the filter plates during steam filtration have significant drawbacks. First, the main function of the filter plate is to remove impurities and dust particles from the flowing steam, thus protecting the waste heat recovery equipment and ensuring steam recovery efficiency. If the filter plate is not cleaned regularly, the gradual accumulation of dirt will cause blockage, reducing the steam flow space and obstructing airflow, further reducing steam recovery efficiency. Therefore, we aim to design a steam heat exchange secondary utilization device to solve this problem. Utility Model Content
