The invention discloses a primary air flow field adjusting structure based on a flow equalizing technology. The primary air flow field adjusting structure comprises a hot air pipeline, a cold air pipeline, an air measuring element and a cold air bellow, wherein one end of the hot air pipeline is a hot air inlet, and the other end of the hot air pipeline is a coal mill access port; one end of the cold air pipeline is fixedly communicated with the hot air pipeline close to the hot air inlet; the air measuring element is fixedly mounted on the hot air pipeline; and the cold air box is used for evenly distributing cold air in the hot air pipeline and reinforcing mixing of the cold air and the hot air, and is fixedly installed in the hot air pipeline. According to the primary air flow field adjusting structure based on the flow equalizing technology disclosed by the invention, the problem that a primary air flow field at an inlet of an existing coal mill is extremely uneven in distribution can be solved. 本发明公开了一种基
