Method and system for adjusting angle of nozzle

The invention relates to the technical field of dust removal, in particular to a method and system for adjusting the angle of a nozzle. The method and system for adjusting the angle of the nozzle areapplied to a rolling system comprises a roller and a dust removal nozzle, wherein the dust removal nozzle is arranged on a wiper of the roller. The method comprises the steps that the diffusion area of dust generated by the roller is determined; the dust removal area of the dust removal nozzle is determined; the target spraying angle range of the dust removal nozzle is determined based on the diffusion area and the dust removal area; and the current spraying angle of the dust removal nozzle is adjusted based on the target spraying angle range. According to the method and system for adjusting the angle of the nozzle, not only can the dust removal effect of the dust removal nozzle be ensured, but also the dust removal efficiency of the dust removal nozzle is ensured. 本发明涉及除尘技术领域，尤其涉及调整喷嘴角度的方法及系统，应用于包含轧辊和除尘喷嘴的轧制系统中，所
