Biomass gasifying hydrogen making reactor based on induction heating

Abstract

The invention relates to the field of renewable energy source, in particular to a biomass hydrogen making reactor based on induction heating and circulating fluidized bed technology. The reactor is characterized in that one side of an upper casing of the reactor is connected with a cyclone dust remover, the other side is connected with a biomass inlet, and the bottom is sleeved with a cylindrical lining; induction heating pieces are hung in the cylindrical lining; an electric induction coil is wound at the outer part of the cylindrical lining, and both ends of the electric induction coil are led out and connected with an induction heating power supply; the bottom of the cylindrical lining is sleeved with a lower casing; a wind distributing plate is arranged in the lower casing; a high-temperature water vapor inlet is arranged at the bottom of the cylindrical lining; a material return device is connected with the bottom of the cyclone dust remover and a material return opening; and the bottom of the material return device is provided with a material return vapor inlet. The electric induction coil is a hollow copper pipe which is wound on the cylindrical lining, and the induction heating pieces are a plurality of cylinders. The invention has the advantages of uniform heating, energy saving, environment protection, continuous running, simple structure and the like, and can be used for preparing hydrogen-enriched synthetic gas by utilizing biomasses of straws, rice hulls, sawdust and the like.

Description

technical field [0001] The invention relates to the field of renewable energy, in particular to a biomass hydrogen production reactor based on induction heating and circulating fluidized bed technology. Background technique [0002] my country is a large agricultural country with abundant biomass resources. Traditional treatment methods (cooking, field burning, and open-air accumulation) not only result in low-efficiency utilization of biomass resources, but also pollute the environment. The in-depth development and utilization of biomass energy, an abundant renewable resource in rural areas, is an inevitable trend in the development of the energy industry in the future, and it is also the only way to ensure the sustainable development of society. [0003] When biomass is gasified, oxygen, air or water vapor can be selected as the gasification agent. When air is used as the gasification agent, part of the biomass undergoes an oxidation reaction with oxygen in the air to rel...

Problems solved by technology

At present, the common heating method is mostly the traditional resistance wire external heating method. Its disadvantage is that repeated heating will easily cause the resistance wire to be brittle, reduce the service life of the heating device, take a long time to heat up, and have low heating efficiency.

[0004] Chinese patent application number is 200710022295.2 patent application (heat pipe heating double fixed bed biomass reactor system) specification discloses a kind of heat pipe heating double fixed bed biomass reactor, the reactor uses two fixed beds as gasification The reactor or reaction chamber uses the working medium in the closed heat pipe as the heat carrier to indirectly provide the reaction heat required for the gasification reaction of biomass and water vapor, but the structure of the device is complex, especially the sealing requirements are high, if individual Leakage of heat pipe components will affect the overall operation of the system

[0005] The specification of Chinese patent application number 200910116483.0 (internal combustion heating rotary cone biomass gasification furnace) discloses a rotary cone biomass gasification reactor, which is composed of two concentric cones inside and outside, and the inner cone does not move. The outer cone rotates around the shaft, and the inner bearing supporting the extension shaft must be able to work for a long time under high temperature and high dust conditions. In addition, this reactor requires inert heat carriers such as sand to move intermittently between the two cones. The wear of the high-temperature wall is quite serious, so it has the disadvantages of complex structure, high cost, and short service life.
