Abstract

The invention discloses a revolving-scraper type biomass pyrolysis reactor, which belongs to the field of biomass pyrolysis equipment. The revolving-scraper type biomass pyrolysis reactor comprises a heating cylinder, a revolving drum, a temperature control instrument, a dynamic seal, a bearing, a spray header, a hopper, a charging threaded rod, a charging motor, a circulating pump, a recirculated cooling liquid pipeline and an oil-water collecting cylinder, wherein the revolving drum is composed of a revolving shaft, a revolving-shaft through hole, a through hole of an external cylinder of the revolving drum, a revolving scraper, heat insulation cotton, a fixed wing and the external cylinder of the revolving drum. By using the reactor disclosed by the invention, the integration of a pyrolysis device, a cyclone separation device and a scrubbing-condensing device is truly realized; just through changing the preset temperature of the temperature control instrument and the revolving speeds of a revolving drum speed regulating motor and a charging speed regulating motor, the productivities of three products comprising biological oil, combustible gas and biomass carbon can be adjusted; and compared with the existing biomass pyrolysis reactor, the pyrolysis temperature is reduced by 100-150 DEG C.

Description

technical field

[0001] The invention relates to biomass pyrolysis equipment, in particular to a rotary scraper type biomass pyrolysis reactor capable of integrating the functions of pyrolysis, cyclone separation and washing and condensation at a relatively low pyrolysis temperature. Background technique

[0002] Biomass pyrolysis technology is the most promising biomass energy conversion technology in the 21st century, and the biomass pyrolysis reactor is the key equipment in biomass pyrolysis technology. Biomass pyrolysis refers to the chemical decomposition process in which biomass macromolecules are degraded by heating in the absence of oxygen or oxygen, and finally bio-oil, combustible gas and biomass charcoal are produced. It is also called dry distillation in industry. . In recent years, due to the increasing shortage of conventional energy sources, the research on biomass pyrolysis technology has been highly valued at home and abroad.

[0003] At present, the common...
