Abstract

The invention discloses a lignite upgrading device. The lignite upgrading device sequentially comprises a rotary table heater, a gas-solid separator, a semi-coke cooler and a tar condenser, and is characterized in that the rotary table heater comprises a rotary table, a heating part, a plurality of rotating wheels, motors and a circular orbit, wherein the circular orbit is arranged at the bottom of the rotary table; the rotating wheels are fixedly arranged below the circular orbit along the circumference of the circular orbit; the circular orbit is suitable for sliding along the rotating wheels and driving the rotary table to rotate, so that the rotary table can stably rotate, and meanwhile, the rotating wheels can drive the rotary table to finish large-scale lignite drying and thermolysis processes; generated semi-coke is cooled in a rotary cooling drum, cooling water becomes steam after being heated, the heat of the steam is recycled through a steam utilization unit, and cooled water is continued to be recycled in the semi-coke cooler, so that the lignite upgrading efficiency and a lignite upgrading effect are improved. The lignite upgrading device is suitable for a lignite material upgrading process.

Description

technical field [0001] The invention relates to a lignite upgrading device, which belongs to the technical field of coal upgrading. Background technique [0002] Lignite is a coal with low heat production efficiency. It has high moisture content, low calorific value, and is easy to weather and spontaneously combust. In order to improve the heat production efficiency of lignite, it is generally necessary to upgrade lignite before use. The upgrading of lignite is mainly a process of directly or indirectly drying and pyrolyzing lignite to remove internal free water and adjust the internal composition and structure of lignite. For example, Chinese patent document CN102250633A discloses a method for upgrading lignite with an externally heated rotary furnace. After the lignite is dried and desorbed in a rotary drying furnace at 100-300°C, it is then put into a rotary carbonization furnace at 450-700°C. The pyrolysis time is 40min-2h. After pyrolysis, semi-coke and high-temperatu...
