Description

Processing system and processing technology for biomass fuel manufacturing raw material

Technical Field

The invention relates to the technical field of biomass fuels, in particular to a processing system and a processing technology for biomass fuel manufacturing raw materials.

Background

The biomass fuel is a novel clean fuel which is formed (such as blocks, particles and the like) by using agricultural and forestry wastes, such as straws, sawdust, bagasse, rice chaff, wood chips and the like as raw materials and is directly combusted through the processes of crushing, mixing, extruding, drying and the like.

Taking the wood chips as raw material to make biomass fuel as an example, in the drying process, the wood chips are usually subjected to drying treatment in a stacking manner, the diffusion range of hot air in the wood chip stack is narrow, the wood chips at the outer layer of the wood chip stack are obviously subjected to drying to a higher degree than those at the inner layer, and thus, the drying speed of the whole wood chip stack is uneven, so that part of the wood chips are over-dried, and part of the wood chips are under-dried.

In addition, there is a problem in that the existing hot wind is directly blown to the chips, and when the hot air flow is continuously supplied into the apparatus, the air pressure inside the apparatus is gradually increased to cause explosion risk, and if the hot air is flown upward in the case that the apparatus is configured in an open structure, a large amount of hot air flow is lost.
