Problems solved by technology

Another example is the fixed bed pyrolysis reactor, which is more suitable for the pyrolysis gasification and pyrolysis carbonization of biomass solid particles, but not suitable for the pyrolysis liquefaction of biomass solid particles, and due to the relative Stability and poor thermal conductivity of biomass will inevitably cause problems such as uneven bed pyrolysis, which limits the pyrolysis capacity of the fixed-bed pyrolysis reactor under air-isolated conditions

Abstract

The invention relates to a novel biomass solid particle pyrolysis reactor and solves the problem that the prior pyrolysis reactor can not be used in pyrolysis gasification, pyrolysis liquefaction andpyrolysis carbonization. The flat-shaped pyrolysis reactor is of horizontal type, wherein, the upper part of one end of the pyrolysis reactor is communicated with a screw feeder which is used as a feed inlet, while the lower part of the other end is provided with a pyrolytic carbon outlet and the upper part of the middle part is provided with a pyrolysis gas outlet; moreover, the pyrolysis gas outlet inclines 20 degrees to 45 degrees relative to a horizontal plane, while the feed inlet is higher than the pyrolytic carbon outlet. Under the condition of air isolation, the invention realizes pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization of biomass solid particle according to requirements through regulating the vibration frequency of the pyrolysis reactor, the inclination angle of a bottom wall surface and the heating temperature, thereby having stronger versatility; moreover, with a simple structure and reliable operation, the pyrolysis reactor does not need to be charged with fluidized carrier gas with the inside provided with no moving part.

Description

technical field [0001] The invention relates to process equipment for pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization of biomass solid particles. Background technique [0002] Biomass solid particles can be pyrolyzed under air-isolated conditions to obtain three products: gas, liquid and solid, and the yields of the three products are related to the heating temperature and heating rate: The pyrolysis product is mainly gas, so it is called pyrolysis gasification (also known as dry distillation gasification); the pyrolysis product under medium temperature (450-550°C) and rapid heating conditions is mainly liquid, so it is called pyrolysis liquefaction; medium temperature (400 °C) ~500°C) and slow heating conditions, the pyrolysis product is mainly solid, so it is called pyrolysis carbonization. Regardless of the pyrolysis conditions, the three products can be used not only as fuel, but also as chemical raw materials. [0003] At home and abroad, a ...
