Problems solved by technology

[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

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention will be further described:

[0021] The present invention is a double-fixed-bed biomass reactor device and its heat utilization system utilizing heat pipes for heat supply. Separator 23, steam generator 7, steam superheater 4, air preheater 5, gas storage cabinet 10 and screw feeder 6. Reactors 1 and 2 are respectively equipped with the same feed ports 25 and 26, partial gas inlets 20 and 22, reactor 1 combustion air inlet or superheated steam inlet 19, reactor 2 combustion air inlet or superheated steam inlet 21. Reactor 1 gas outlet or flue gas outlet 27, reactor 2 gas outlet or flue gas outlet 28, ash outlets 35 and 36. Between reactors 1 and 2, there are combustion-supporting air inlet reversing valve 11, superheated steam inlet reversing valve 12, biomass inlet reversing valve 13, gas outlet or flue gas outlet reversing valve 14 and 15, part of the gas Inlet reversing valve 16. The heat pipe 3...

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 the reaction 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 resolved existing 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...
