AI Technical Summary
In existing blast furnace slag flushing water heat exchange devices, the blast furnace slag flushing water comes into direct contact with the heat exchange tube bundle, causing large particles of impurities to impact the heat exchange tube bundle, making it prone to deformation and resulting in low practicality.
The design includes heat exchange tubes, heat exchange frames, and flow guiding components. The flow guiding components allow the blast furnace slag flushing water to flow spirally along the outer wall of the heat exchange frame. Centrifugal force is used to move impurities, avoiding direct impact on the heat exchange tubes. This is combined with industrial circulating water for dual heat exchange.
It effectively prevents deformation of the heat exchange tube bundle, improves the practicality of the device, prevents impurity accumulation, and enhances heat exchange efficiency.
