Abstract

The invention discloses a device and method for biomass carbonization and co-production of combustible gas in a single-chamber internal heating rotary furnace. The method includes adding the dried biomass raw material into the stable combustion rotary furnace body, carrying out pyrolysis and carbonization in the inner cylinder body along the slope of the cylinder body, and realizing the high-temperature separation of the carbonized material and the combustible fuel gas, and pyrolyzing the oil gas. Through the stable combustion system, the incomplete combustion continues and stably with the naturally inhaled air above the furnace. The heat released is used for subsequent pyrolysis. Further activation or upgrading for various uses. The device of the present invention uses a micro-negative pressure internal heating type heat supply, does not need a separate combustion chamber, has a compact structure, high heat utilization efficiency, and waste heat can be recovered, and solves the problem of high energy consumption in the carbonization process in the production process of biomass activated carbon.

Description

technical field [0001] The invention belongs to the technical field of utilization of biomass resources, and in particular relates to a device and method for biomass carbonization and co-production of combustible gas in a single-chamber internal heating rotary furnace. Background technique [0002] Biomass energy is chemically stored in biomass by solar energy and can be converted into conventional solid, liquid, and gaseous fuels. It is a renewable energy source and the only renewable carbon source in nature. Biomass energy has many advantages such as renewable, low-carbon and clean, and has a wide range of sources. In the context of the increasingly serious energy and environmental problems brought about by traditional energy sources, the development and utilization of biomass energy has prominent strategic significance. [0003] Biomass pyrolysis and carbonization technology is an important way to develop and utilize biomass energy. Biochar has the characteristics of st...
