Abstract

The invention relates to a coal variable-amplitude vibration fluidized bed drying and sorting system and a sorting method and belongs to the technical field of coal drying and sorting devices. The coal variable-amplitude vibration fluidized bed drying and sorting system is used for solving the technical problem that an existing coal drying device is poor in drying effect, and the sorting efficiency is difficult to improve. The drying and sorting system comprises a drying and sorting unit, an air supply unit, a feeding unit, a discharging unit, an induced draft dust-removing unit and a supporting unit. The air supply unit and the induced draft dust-removing unit are connected with the bottom and the top of the drying and sorting unit correspondingly. The supporting unit is used for supporting the drying and sorting unit. The drying and sorting unit is internally provided with a dividing plate and is divided into a drying section bed body and a sorting section bed body, wherein the top of the drying section bed body and the top of the sorting section bed body are provided with a drying section vibration exciting device and a sorting section vibration exciting device correspondingly,and the vibration amplitude of the drying section vibration exciting device is larger than that of the sorting section vibration exciting device. The coal variable-amplitude vibration fluidized bed drying and sorting system achieves integration of drying and sorting and has the characteristics of a good drying effect, high sorting efficiency, low cost, wide application range, convenient operationand the like.

Description

technical field [0001] The invention relates to the technical field of coal drying and sorting machinery, in particular to a coal drying and sorting system and method for a variable-amplitude vibrating fluidized bed. Background technique [0002] With the development of my country's economy, the total energy consumption is increasing year by year. Coal, as the main energy source, provides strong support for my country's economic development. develop and use. Lignite is a low-quality coal with high water content and easy muddying. It is easy to oxidize in the air and difficult to store and transport. However, it has abundant reserves and is mainly distributed in alpine and water-scarce regions such as Inner Mongolia, Yunnan, Northeast China, and Sichuan. [0003] In recent years, with the promotion and support of national policies, the development and utilization of lignite has become a new hot spot. Due to its high water content and low calorific value, its use is greatly l...
