Description

Technical Field

[0001] This invention belongs to the field of air compressor heat recovery technology, and particularly relates to an air compressor heat recovery mechanism with a slag removal component. Background Technology

[0002] Currently, an air compressor is a device used to compress gas. During operation, most of the input electrical energy is converted into heat energy and stored in the lubricating oil. If this heat energy cannot be effectively released during operation, the air compressor will alarm and shut down due to overheating. Furthermore, lubricating oil contains a significant amount of heat energy; utilizing this heat energy would greatly improve heat recovery and meet energy conservation and emission reduction requirements. Traditional air compressors often use water or air cooling to circulate and recover heat from the compressor's hot oil. This is achieved by introducing the lubricating oil from the air compressor into a heat recovery water tank, where it is heated... After recovery, the lubricating oil is then discharged into the air compressor, thus achieving continuous lubricating oil heat recovery. This not only cools the lubricating oil, improving equipment operational stability, but also recovers the heat from the lubricating oil, achieving energy savings. However, currently, the lubricating oil is generally fed into multiple oil distribution pipes inside the heat recovery water tank, where it is rapidly conducted through these pipes. After long-term use, a large amount of scale will adhere to the outer surface of these pipes, which will greatly reduce the heat recovery efficiency. Therefore, it is necessary to upgrade and modify the existing heat recovery structure to improve heat recovery efficiency and enhance the ease of use and flexibility of the device.
