Abstract

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.

Description

technical field [0001] The invention relates to the technical field of the primary air flow field at the inlet of a coal mill, in particular to an adjustment structure for the primary air flow field based on the flow equalization technology. Background technique [0002] The coal mill is the key equipment for crushing the material after it is crushed. The coal mill is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics. Dry or wet grinding of various ores and other grindable materials. [0003] When the coal mill is running, it is necessary to introduce a primary air flow field at the entrance of the coal mill to improve the safety and economy of the coal mill operation. The primary air flow field is connected by cold and hot air pipes and formed by mixing. The existing The mixing distance of cold and hot air is extremely short, and it is difficult to pe...
