AI Technical Summary
In the treatment of high-temperature flue gas from crude copper smelting, low gas-liquid mass transfer efficiency and filter medium blockage are long-term technical bottlenecks. Traditional spray towers rely on static fillers or simple atomization, which leads to droplet aggregation and sedimentation, and the active absorption liquid is lost without sufficient contact. The viscous salt crystals and smoke dust mixture generated by wet desulfurization quickly solidify. Traditional vibration and cleaning devices cannot penetrate the wet slag layer, resulting in frequent shutdowns for flushing, redundant energy consumption and space conflicts.
A rotating spoiler is used to form a high-intensity three-dimensional turbulent field. Combined with the high-frequency centrifugal knocking of the co-drive motor, it dynamically cuts the airflow and penetrates the wet slag layer, achieving deep mixing of gas and liquid and self-cleaning of the filter medium. Through the synergistic effect of the spraying mechanism and the collection mechanism, efficient flue gas purification and waste heat recovery are achieved.
Significantly extend the reaction residence time, improve droplet utilization, achieve near-limit removal rate of sulfur dioxide, avoid filter material damage, reduce maintenance shutdown frequency, and improve environmental friendliness and economic benefits.
