Problems solved by technology

That is to say, the above-mentioned pyrolysis reactor is not suitable for continuous operation, and the residence time of the pyrolysis gas in the reactor is still relatively long, which will cause the gaseous tar to easily undergo secondary decomposition, and then reduce the tar yield

Abstract

The invention discloses a carbon material pyrolysis device which can be used to greatly raise the yield of liquid pyrolysis products. The device provided by the invention comprises a pyrolyzing furnace which is used for pyrolyzing a carbon material therein and is a moving bed, fixed bed or vibration bed pyrolyzing furnace, at least a gas collecting tube and at least an air blowpipe which are positioned inside the pyrolyzing furnace, wherein walls of the gas collecting tube and the air blowpipe are respectively provided with at least one gas channel which passes through the wall and is used for communicating the gas collecting tube and the air blowpipe. A gas pyrolysis product generated in the pyrolyzing furnace passes through the gas collecting tube and is rapidly discharged out of the pyrolyzing furnace; a sweeping gas from the outside of the pyrolyzing furnace passes through the air blowpipe and is conveyed into the pyrolyzing furnace; and the gas pyrolysis product in the pyrolyzing furnace is swept into the gas collecting tube.

Description

technical field [0001] The invention relates to a carbonaceous material pyrolysis or dry distillation device, in particular to a carbonaceous material pyrolysis device capable of increasing tar yield. Background technique [0002] The medium and low temperature pyrolysis and dry distillation technology of carbonaceous materials, as a carbonaceous material conversion and utilization technology that meets the requirements of clean energy, has become an important research direction for the rational use of coal and other carbonaceous material resources. [0003] Generally, the majority of solids such as coke, semi-coke, etc.; liquids, such as tar, aqueous solution, etc.; and gases, such as carbon dioxide, carbon monoxide, methane, etc., can be obtained by pyrolysis or dry distillation of carbonaceous materials. Among the various products mentioned above, liquid products such as tars are of high value as a source of many important chemicals, however, their yields are relatively l...
