Problems solved by technology

For example, the tar content is high, the gasification efficiency is low, the yield is low, the concentration of combustible gas in the gas is low, the stability of the gasification system is poor, the quality of biomass combustible gas is difficult to control, and the adaptability to raw material types and particle sizes is poor, etc.
[0005] On the other hand, with urbanization and the construction of new countryside, the amount of agricultural and forestry waste generated in rural areas is increasing, especially the non-degradable organic waste such as electronic products, waste tires, etc. will inevitably occupy land, while landfill Burying will cause future groundwater pollution

Abstract

The invention discloses a method and a device for synthesizing a natural gas from wind/solar hybrid generation pyrolysis catalytic biomass. Renewable energy sources such as wind energy, solar energy and biomass are combined with electrolyzed water, water can be electrolyzed through wind and solar power generation, the biomass and organic wastes can be pyrolyzed and gasified, products oxygen and hydrogen obtained from the electrolyzed water can be respectively used as a biomass gasification agent and a methane synthesis gas, the gas obtained by gasifying the biomass and the organic wastes through catalysis can be converted into a synthesized natural gas which is supplied as energy, the technical problems that the solar energy and the wind energy are poor in stability and hard to store, the concentration of a combustible gas in the biomass gasified gas is low, the combustible gas quality is hard to control and the like can be effectively solved, and a sustainable energy supply system which can comprehensively utilize the solar energy, the wind energy and the biomass energy is provided.

Description

technical field [0001] The invention relates to a method for storing solar energy and wind energy, cleanly utilizing biomass, and treating and disposing of organic waste. The invention converts solar energy and wind energy into electric energy through an electric energy conversion system, and then uses the electric energy for pyrolysis gasification of biomass and organic waste and electrolysis of water, and converts the gas obtained by gasifying biomass and organic waste through catalysis It is synthetic natural gas for energy supply in towns and rural communities. Background technique [0002] With the rapid increase of the global population and the development of the world economy, the consumption of petrochemical energy such as coal and oil is increasing rapidly, and the depletion of energy is imminent. A series of environmental pollution problems such as soil erosion, soil desertification, and greenhouse effect have aroused serious attention from all over the world. St...
