Problems solved by technology

In this way, it is difficult to obtain a higher drying or pyrolysis temperature, that is, it cannot meet the needs of more coal types
Moreover, the gas distribution structure of this air chamber has problems such as occupying the space at the bottom of the bed, making it difficult to support and expand the diameter, which limits the application of the rotating fixed bed

Abstract

The invention discloses a disc type reactor which comprises a drying or pyrolyzing tray (1), a rotation driving device used for driving the tray (1) to rotate and a gas distributing device used for conveying high-temperature gas into the tray (1). The gas distributing device comprises a gas distributing unit which is arranged under the tray (1) and can rotate along with the tray (1) and a hot blast main pipe (2) used for supplying gas to the gas distributing unit. The gas distributing unit communicates with the upper space of the tray (1), and the rotation driving device is located outside the gas distributing device. By adoption of the disc type reactor, higher drying or pyrolyzing temperatures can be obtained, and therefore the disc type reactor can meet pyrolyzing and upgrading requirements of coal of more types, central gas supply is adopted, and the height of a bed can be effectively decreased.

Description

technical field [0001] The invention relates to the technical field of drying or pyrolysis equipment, in particular to a disc reactor. Background technique [0002] Lignite is a kind of coal with high water content (generally 20%-60%), low calorific value (about 2500-4500 kcal / kg), high volatile content (about 40%-50%) (dry without gray base). Lignite is widely distributed all over the world. In my country, lignite storage is also very rich, accounting for about 40% of my country's coal storage, mainly distributed in Yunnan, Inner Mongolia, Northeast China, Sichuan and other provinces. Lignite has the characteristics of low market value, high transportation costs, low power generation efficiency, and difficult gasification technology. Therefore, the market value of this type of coal is far lower than that of high-quality coal, and it needs to be pyrolyzed to upgrade. Using gas heat carrier technology to pyrolyze lignite can extract pyrolysis oil from it and process it into...
