Abstract

The invention provides a biomass dry distillation pyrolysis device, which consists of a rotary baking chamber, a rotary dry distillation pyrolysis chamber, a biomass feeding system, a charcoal discharge cooling system, a biomass fuel gas purification system and a flue gas system. The rotary baking chamber is equipped with a first feed end and a first discharge end, and the first feed end is connected to the biomass feeding system. The rotary dry distillation pyrolysis chamber is equipped with a second feed end and a second discharge end, the second feed end is connected to the first discharge end, and the second discharge end is connected to the charcoal discharge cooling system. The first feed end of the rotary baking chamber is provided with a flue gas port, which is connected to the flue gas system. The second feed end of the rotary dry distillation pyrolysis chamber is equipped with an air suction port, which is connected to the biomass fuel gas purification system. The device has the advantages of simple structure, compact layout and strong continuous operation ability.

Description

technical field [0001] The invention relates to a biomass dry distillation pyrolysis device. The pyrolysis device uses agricultural and forestry waste and other material fuels as raw materials, and the final products include charcoal, biomass pyrolysis gas, biomass tar and waste heat, and belongs to the biomass pyrolysis system. Carbon, gas technology field. Background technique [0002] Biomass energy is a widely distributed renewable energy, but it has disadvantages such as low energy density and difficulty in collection. Biomass pyrolysis refers to the process in which biomass is heated to a certain temperature and decomposed into charcoal, tar and pyrolysis gas under the condition of isolation of air or a small amount of air. Domestic and foreign studies have shown that biomass pyrolysis is an effective way to utilize agricultural and forestry waste biomass, and has considerable application prospects. According to different heating methods, biomass pyrolysis is divided...
