Developed countries and regions in the world, such as Australia, the United States, Germany, and other countries, have specialized agencies to conduct research on the application of lignite drying, seeking economically effective lignite drying and dehydration methods, and a new set of new products that raise the calorific value of lignite as the final control target. technology. For the small-quantity lignite upgrading and drying, various equipments such as a tumble dryer, a multiple-return dryer, a boiling dryer, and the like can be used, which have obvious advantages for the large-volume lignite vibrating fluidized bed drying technology. Vibrating fluidized bed technology is currently the most advanced technology for domestic lignite drying, and is also the most promising technology. However, because of the physical and chemical characteristics of lignite itself, it is characterized by large particle size and uneven distribution, large water content, high volatility, and large dry output. The conventional vibrating fluidized bed drying technology cannot adapt. Therefore, the large-scale vibrating fluidized bed lignite drying technology has become an important technological innovation for lignite drying technology. The large-scale vibrating fluidized bed dryer pioneered by Shenyang Yitong Venture Drying Equipment Co., Ltd. is the most advanced dryer in the field of coal drying and coal moisture conditioning, with an output of up to 200 tons per hour. Due to the application of vibrating fluidized bed drying technology, a low-temperature and large-air-volume drying process is used. With the large-scale boiling combustion and multi-level dehumidification cycle technology, the thermal efficiency is increased by 20%, and the raw coal with water content of 30%-50% can be reduced by 200%. %-30% moisture increases calorific value (low calorific value) to 3500-4000 calories. The vibrating body of large brown coal vibrating fluidized bed dryer adopts the international advanced CARR vibration technology. The quality of the parametric vibration is small and the strength of the bed structure is high. Multi-stage gas distribution plates and individually adjusted vibration parameters to suit the requirements of the material in different drying stages. The fluidized drying space is divided into chambers to control the inlet air temperature of each chamber according to different coal quality and drying process requirements, so that the drying process technology is more reasonable. Along the direction of the material, the opening rate, air temperature, and air volume of the gas distribution plate can be individually adjusted and controlled.
