System for preparing biomass rod-shaped particles

Abstract

The invention relates to a system for preparing biomass rod-shaped particles, which comprises a conveying device, a pre-cleaning screen, a drying system, a stock bin, a granulator, a cooling device and a vibration classifying screen, wherein the conveying device is used for conveying biomass materials or fuel; the pre-cleaning screen is used for screening and eliminating large biomass materials and impurities; the drying system is used for drying the biomass materials; the stock bin is used for storing the biomass materials and fuel or formed particles; the granulator is used for compressing the biomass materials into biomass particles; the cooling device is used for cooling the biomass particles; and the vibration classifying screen is used for screening the biomass formed particles according to the size. By using agriculture and forest wastes (such as stover, bagasse, rice chaff, bark, branches and sawdust) as the raw biomass materials and compressing the raw biomass materials into particles or rods by means of special forming equipment through crushing, extrusion, drying and other processes, the preparation system ensures that the particles or rods are about ten times higher in energy density as compared with the raw biomass materials not subjected to processing, facilitates the transportation and storage processes and achieves a high combustion efficiency.

Description

technical field [0001] The invention belongs to a molding fuel preparation system, in particular to a system for preparing biomass stick particles. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent. The main energy sources currently used by human beings are oil, natural gas and coal. According to the statistics of the International Energy Agency, the lifespan of these three kinds of energy for human exploitation on the earth is only about 35 years, 50 years and 240 years respectively. On the one hand, fossil resources such as coal and oil are increasingly depleted, and energy supply continues to be tight; on the other hand, the excessive use of fossil resources has caused increasingly serious environmental problems. Therefore, developing and searching for new alternative energy sources has become a major issue that must be resolved in the new century for the sustainable dev...
