Double-fixing-bed biomass reactor system of supplying heat by heat pipe

Abstract

This invention relates to a double fixed bed live material reactor system which using the heat pipe to provide heat. This invention has the cyclone separator, the steam generator, the steam superheater, the air pre-heater. The technical feature lies in that it has two same fixed beds and the heat transfer part heat pipes. When the lives material reacts, a fixed bed are taken as the combustion chamber, another fixed bed as reaction chamber. After the living material respond finished, the original work for combustion chambers fixed bed transfers to the reaction chamber, the original work for thereaction chamber fixed bed transfers to the combustion chamber. The heat transfer part heat pipe crosses two fixed beds, a section in a fixed bed, a section in another fixed bed. The flaw is resolvedexisting technical existence's fresh material own combustion produced to include massive N2 to cause calorific value Gao Huo not to take the gasifying agent with the overheated steam to cause the cost which increases. This invention's two fixed bed achievement gasifies the reactor or the combustion chamber in turn, realizing the biological archery target indirect heating gasification, the calorific value's increasing, generally might achieve 10-15MJ / m3.

Description

technical field [0001] The invention relates to a biomass reactor, in particular to a double fixed-bed biomass reactor system using heat pipes for heating. Background technique [0002] Before the present invention, air was mostly used as the gasification agent in biomass fixed bed gasification, and its main disadvantage was that the reaction heat was provided by the combustion of biomass itself, and the gas produced contained a large amount of N 2 , the calorific value is not high. If superheated steam is used as the gasification agent, heat must be supplied externally to provide the necessary reaction heat, which increases the cost. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects and provide a double fixed-bed biomass reactor system with heat pipe heating. [0004] Technical scheme of the present invention is: [0005] The double fixed bed biomass reactor system with heat pipe heating includes cyclone s...
