Saturated steam process for biomass fuel processing

Abstract

The invention discloses a saturated steam process for biomass fuel processing. The invention belongs to the technical field of biomass fuels. The invention discloses a saturated steam process for biomass fuel processing. According to the invention, a comprehensive treatment pipe can be innovatively arranged to carry out comprehensive treatment on the generated biomass gas; on one hand, non-contactefficient heat exchange is carried out between a heat exchange adsorption soft rod and biomass gas, therefore, the purpose of cooling is achieved; in addition, water vapor generated in the cooling process is guided into a gasification furnace for secondary recycling; on the other hand, densely distributed heat exchange adsorption soft rods can form a structure similar to a space net, tar in fuelgas is efficiently adsorbed, dust is synchronously adsorbed and captured on the basis of the viscosity characteristic of the tar, the purity of the biomass fuel gas is remarkably improved, cooling liquid can be recycled, the processing procedure chain is shortened, meanwhile, the processing cost is effectively controlled, and the environment-friendly concept of sustainable development of the current society is met.

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
