Application Improvement of sealing steel brush in energy saving

Waste heat utilization is an important aspect of sintering energy saving. At present, many sintering plants in China have built waste heat power generation systems. Originally, waste heat power generation is a mature technology, but in practical application, it has been large and inefficient. There are two main reasons: first, the exhaust gas is not well recycled; Second, the air leakage of the system causes low temperature of the exhaust gas discharged from the cooler, which is difficult to recover and low efficiency of waste heat utilization.
The flexible magnetic seal of the ring cooler is a new technology developed to solve the air leakage of the ring cooler. Its sealing method can greatly reduce the air leakage, on-site dust and noise, and improve the efficiency of waste heat power generation. A flexible compensating sealing system of a ring cooler, wherein the root of a dynamic sealing brush is fixed on a dynamic sealing frame, and the tip of the dynamic sealing brush is on the contact surface of the ring cooler frame, and is in damping sealing contact with the contact surface of the ring cooler frame; The root of the flexible guide device is fixed on the sealing compensation device, and the sealing compensation device is fixed on the framework of the ring cooler through the connecting device; The brush tip of the flexible guide device is placed on the sealing panel at the bottom of the trolley and is in damping sealing contact with the sealing panel at the bottom of the trolley. With the utility model, the harmful air leakage of the ring cooler is significantly reduced, the cooling is improved, the phenomenon of "red ore running" can be eliminated, and the passive situation in the previous production is improved, resulting in: 1. The belt loss is greatly reduced, and the operation rate of the sintering machine is improved. 2. The sealing system does not need frequent maintenance and replacement. 3. Reduce power consumption. 4. The environment is protected and the maintenance cost and human resources are greatly reduced.
