Abstract
The invention discloses a carbonaceous material pyrolysis device, a pyrolysis system comprising the pyrolysis device and a method for pyrolyzing carbonaceous materials. The pyrolysis device comprises a pyrolysis furnace and a material distributor, wherein carbonaceous materials are pyrolyzed in the pyrolysis furnace; the material distributor extends from the upper part or the top part to the lower part or the bottom part of the pyrolysis furnace; when the mixture of the carbonaceous materials and solid thermal carriers moves from top to bottom, the material distributor enables the mixture to be uniformly distributed along the pyrolysis furnace radially; the material distributor comprises a plurality of blades and / or conical objects; the blades and / or conical objects are alternatively distributed in the internal space of the pyrolysis furnace, thereby forming a plurality of cloth material layers from top to bottom which are spaced longitudinally at intervals and are mutually staggered horizontally. The pyrolysis device provided by the invention can enable the carbonaceous materials and the solid thermal carriers to be mixed and / or distributed more uniformly, thereby preventing layering or segregation of the mixture of the carbonaceous materials and the solid thermal carriers, and enabling thermal transfer to be more uniform.
Description
technical field [0001] The present invention relates to a carbonaceous material pyrolysis device, a pyrolysis system including the pyrolysis device, and a method for pyrolyzing carbonaceous materials, in particular to a pyrolysis device with self-uniform mixing and self-uniform distribution of materials, including the pyrolysis device A pyrolysis system of a pyrolysis device in which materials are uniformly mixed and uniformly distributed, and a method for pyrolyzing carbonaceous materials with the pyrolysis system. Background technique [0002] For a long time, low-rank coal, especially lignite, has the characteristics of high moisture, high ash content, high volatile matter, low calorific value, low ash melting point, and poor stability, so it is not suitable for long-distance transportation. At present, low-rank coal mainly It is used as power fuel in some areas, so it cannot be fully exploited and utilized. However, with people's concerns and worries about global energy...
