Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a high-temperature waste heat recovery device. Background Technology

[0002] Many industries currently require equipment that uses high-temperature water. However, in the past, this high-temperature water was simply heated in heaters and then discharged directly after passing through the water-using equipment, resulting in a significant waste of thermal energy. Therefore, a recycling device is needed to effectively utilize this high-temperature wastewater.

[0003] Chinese patent document CN221685297U discloses a high-temperature wastewater waste heat recovery device. The device comprises a cylinder and a base plate. Several sets of support columns are fixedly installed at the bottom of the cylinder, and these columns are fixedly installed on the base plate. A motor and a water inlet pipe are fixedly installed at the top of the cylinder. A filter cylinder is installed inside the cylinder, and a water pipe is installed inside the filter cylinder. One end of the water inlet pipe extends into the filter cylinder. This high-temperature wastewater waste heat recovery device utilizes the coordinated operation of components such as a motor, a reciprocating screw, a stirring blade, a sliding sleeve, a fixed plate, and an annular scraper. The stirring blade agitates the high-temperature wastewater, ensuring it fully contacts the sidewall of the water pipe for better heat conduction. Simultaneously, the annular scraper continuously scrapes along the inner wall of the water pipe, removing scale adhering to the pipe wall, thereby improving the heat conduction effect of the water pipe.

[0004] The aforementioned existing technologies do not include conveniently assembled and fixed heat exchange equipment, which cannot efficiently transfer heat from hot fluids to cold fluid equipment, easily leading to waste of thermal energy resources. Therefore, the market needs to develop a new type of high-temperature waste heat recovery device. Utility Model Content
