Abstract

The invention discloses a device and method for producing low tar and high calorific value combustible gas by three-stage biomass gasification, wherein the device consists of a fluidized bed gasification reactor, a cyclone reforming reactor, a moving bed catalytic reactor and a return The upper part of the fluidized bed gasification reactor is connected with the upper part of the cyclone reforming reactor, the lower part of the fluidized bed gasification reactor is connected with the lower part of the moving bed catalytic reactor through the feeder, and the top part of the cyclone reforming reactor It communicates with the top of the moving bed catalytic reactor; the lower part of the fluidized bed gasification reactor is also equipped with a biomass particle feeding port and the first oxygen-enriched / steam inlet; the upper part of the cyclone reforming reactor is the second oxygen-enriched / Water vapor inlet; the bottom of the feeder is the third oxygen-enriched / water vapor inlet. The invention can effectively solve the problems of low calorific value of gas production and high tar concentration existing in the current biomass gasification process, and produce various high-quality combustible gases that can be directly applied to gas equipment. The system can operate in self-heating mode, with low gasification cost and high energy utilization rate.

Description

technical field [0001] The invention relates to a device and method for producing low-tar and high-calorific-value combustible gas by biomass three-stage gasification, and belongs to the field of solid waste resource disposal. Background technique [0002] With the improvement of my country's urbanization level, the demand for rural energy has increased and the energy structure has changed. The energy consumption of rural households has changed from traditional fuels such as straw and firewood to clean natural gas and liquefied petroleum gas fuels. Biomass resources have become regionalized. , seasonal and structural excesses. A large amount of biomass is directly incinerated, which not only wastes precious resources, but also seriously pollutes the environment. Therefore, how to solve the way out of biomass disposal and realize the efficient recycling of biomass energy has become a major problem to be solved urgently in the construction of new socialist countryside in our ...
