Biomass spiral pyrolytic process and antipyretic device

Abstract

The invention relates to a biomass spiral pyrolytic process and an antipyretic device. In the invention, the spiral pyrolytic process is adopted to pyrolyze biomass materials in a pyrolysis reactor, the materials are added from the upper part of the pyrolysis reactor, high temperature flue gas enters a flue gas separation chamber for shunting from the lower part of the pyrolysis reactor, the direction for the biomass materials to enter the pyrolysis reactor is opposite to the direction for the flue gas to enter the flue gas separation chamber, the high temperature flue gas is used for providing heat for pyrolysis, and the biomass materials are pyrolyzed to obtain biomass and fuels. The antipyretic device, namely the pyrolysis reactor comprises an outer cylinder, an inner cylinder, a heat insulation system and a spiral propeller. Materials slowly enter a pyrolyzer by way of the spiral propeller from an upper feed port, and the biomass is pyrolyzed by the high temperature flue gas at the bottom via the flue gas separation chamber from bottom to top. The biomass spiral pyrolytic process in the invention has the advantages that the flue gas residual heat resources can be effectively used, biomass carbon and fuels can be prepared, the method is simple and feasible, the heat transfer effect is good and the popularization and application values are excellent.

Description

technical field [0001] The invention relates to a biomass spiral pyrolysis process and a pyrolysis device. Background technique [0002] One-seventh of the world's total energy consumption comes from biomass energy. Biomass energy is the only energy source that not only has the properties of fossil fuels, but also has the characteristics of storage, regeneration, and conversion, and is less restricted by natural conditions. Biomass can be converted into useful heat, electricity, fuel for power and valuable chemicals. The main conversion routes are direct combustion, pyrolysis gasification and liquefaction. Currently, among the available technologies, the conversion of biomass into higher-grade and versatile energy products and chemicals through thermochemical processing has attracted special attention worldwide. [0003] Biomass pyrolysis is the use of thermal energy to cut chemical bonds in biomass macromolecules under anaerobic or hypoxic conditions, making them [00...
