Abstract

The invention provides a rotary heating device. The rotary heating device comprises a sealed shell, a rotary material bed, a material inlet pipe and an annular air inlet section, wherein the lower part of the shell is provided with an annular air-distributing groove; the rotary material bed is rotatablely arranged in the shell and is provided with a solid product discharge port and an air inlet gap; the material inlet pipe is arranged above the rotary material bed and is used for conveying materials to the rotary material bed; and the first end of the annular air inlet section passes through the air-distributing groove to be connected with the air inlet gap, and the second end of the annular air inlet section is connected with the outside so as to introduce hot gas into the shell. According to technical scheme provided by the utility model, the rotary heating device enables the hot gas introduced from the bed bottom of a rotary heating device to steadily and uniformly pass through a material layer in a reactor and to implement uniform and stable heat transmission, so that a pyrolysis process becomes uniform and stable, the operation is stable and controllable, and a final product has favorable quality.

Description

technical field [0001] The invention relates to the technical field of drying or pyrolysis of solid carbonaceous materials, in particular to a rotary heating device with a rotary material bed. Background technique [0002] In the context of the increasing shortage of global oil and gas resources, how to rationally utilize coal resources in a low-cost and environmentally friendly way to realize the supplement or even substitution of coal to oil and gas resources has become an important research topic in the energy industry. China's lignite reserves account for nearly 50% of the total coal reserves, and its high water content, high ash content, and low calorific value limit its utilization. The development of new high-efficiency and clean utilization technologies of lignite is one of the directions to be explored in the energy field. [0003] After years of research and experiments, it can be determined that the comprehensive utilization of lignite such as dehydration and upg...
