Abstract

The invention discloses an efficient and energy-saving self-weight spiral progressive biomass pyrolysis system which comprises a pyrolysis furnace, a material distribution tank (23), an air cooler anda water cooling system, wherein an outlet of the material distribution tank (23) communicates with the material feeding hole of the pyrolysis furnace; a biomass charcoal outlet in the bottom of the pyrolysis furnace communicates with a material inlet in the upper part of the air cooler; a material outlet in the lower part of the air cooler communicates with the material feeding hole of the watercooling system; an inner cylinder (2) and an outer cylinder (3) are arranged in the middle inside the furnace body (1) of the pyrolysis furnace; a conical material distributor (4) is arranged at the top, corresponding to the material feeding hole of the furnace body (1), of the inner cylinder (2); a pyrolysis gas secondary pyrolysis tube (5) is arranged in the inner cylinder (2); the outlet of thepyrolysis gas secondary pyrolysis tube (5) communicates with a pyrolysis gas outlet (6); both a flue gas outlet (7) and a hot flue gas inlet (8) communicate with an inner cavity of the inner cylinder(2). Mutual actions of heat conduction are achieved, high heat utilization efficiency is achieved, and gradient utilization of energy is achieved.

Description

technical field [0001] The invention relates to a pyrolysis system, more specifically to a self-weight spiral progressive biomass high-efficiency and energy-saving pyrolysis system, which belongs to the technical field of biomass energy. Background technique [0002] Biomass is organic matter produced by absorbing carbon dioxide from the air through photosynthesis. It is widely distributed, available in large quantities, and is the only renewable natural fuel containing hydrocarbon components and thermal energy that can be stored. [0003] Biomass pyrolysis technology, as a clean and efficient conversion technology, can produce different fuels such as bio-natural gas, bio-oil, and bio-char, or chemical and material supplies. It is a key research direction worldwide. At present, the heat exchange process of an external pyrolysis device is usually used. Due to the short residence time of the material in the pyrolysis furnace and the small heat exchange area between the materi...
