A Saturated Steam Process for Biomass Fuel Processing

Abstract

The invention discloses a saturated steam process for processing biomass fuel, which belongs to the technical field of biomass fuel, and a saturated steam process for processing biomass fuel. The generated biomass gas is comprehensively treated. On the one hand, the heat exchange adsorption soft rod is used to perform non-contact and efficient heat exchange with the biomass gas, so as to achieve the purpose of cooling it, and guide the water vapor generated during the cooling process to the Secondary recycling is carried out in the gasifier. On the other hand, the densely distributed heat exchange and adsorption soft rods can form a space-like network structure, which can efficiently adsorb the tar in the gas and synchronize the dust based on the sticky characteristics of the tar. Adsorption and capture can significantly improve the purity of biomass gas, and the cooling liquid can also be recycled, shortening the processing chain while effectively controlling processing costs, which is in line with the environmental protection concept of sustainable development in today's society.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a saturated steam process for processing biomass fuels. Background technique [0002] Biomass is an abundant renewable resource on the earth. It is a variety of organisms produced through photosynthesis using the atmosphere, water, and land. It is all living and growing organic substances. It is different from traditional petroleum, coal, and nuclear energy. Fuel is a renewable energy substance. The use of biomass conversion to produce biofuels can alleviate the energy crisis and is conducive to environmental protection. Biofuels refer to solid, liquid or gaseous fuels converted from biomass, which can replace petroleum-based fuels. Gasoline and diesel are important directions for the development and utilization of renewable energy. At present, people usually use wood chips, rice husks, straw and other raw materials to convert them into biofuels of different components unde...

Problems solved by technology

[0003] However, the biomass fuel gasification process currently on the market has many consumables, the process is relatively complicated, and the production cost is high. At the same time, the spray cooling method is generally used to cool the biomass gas. Recycling requires a lot of waste of water resources, and the water vapor generated during the cooling process is directly discharged, resulting in waste of resources. The overall process has poor energy-saving and environmental protection effects, and cannot generate saturated steam for external use, and the generated biomass gas There is a lot of dust and tar in it, which requires additional processing steps to separate, further increasing the processing cost and difficulty
