Problems solved by technology

For a long time, after the skin of green hemp has been peeled off, the remaining branches are mainly used as fuel for rural households or discarded as waste, which not only causes a lot of waste of resources, but also pollutes the environment
[0003] The use of green hemp branches to prepare biomass fuel not only achieves environmental protection, but also turns waste into treasure and creates new energy. However, the preparation of biomass fuel currently has technical problems such as not easy to compress and low combustion value, which needs to be solved urgently. solve

Abstract

The invention discloses a preparation method of a biomass fuel easy to compress and having high combustion value. The preparation method comprises the following steps: uniformly mixing and grinding pretreated abutilon branches, sawdust, biogas residue, waste lubricating oil and coal dust, and under the protection of nitrogen, heating, preserving heat and then performing compression moulding to obtain the biomass fuel easy to compress and having high combustion value. The raw material source is very wide, the method is relatively simple, the operability is strong, the cost is low, the obtainedbiomass fuel is high in combustion efficiency, waste material is changed into things of value, new energy is created, repeated use of abutilon branches and some life and industrial wastes is realized,and meanwhile, resource crisis of fuels such as petroleum confronted by the nowadays society is effectively relived, and the problem of environment pollution is reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a method for preparing biomass fuels with easy compression and high combustion value. Background technique [0002] China is one of the countries with the most artificial cultivation of green hemp in the world. Green hemp has the characteristics of fast growth and high yield of branches. The green hemp with medium yield can produce 2000kg of green hemp per mu. Calculated according to the moisture content of branches at 50%, each Mu mulberry field can produce 1000kg of dry branches. For a long time, after the skin of green hemp has been peeled off, the remaining branches are mainly used as fuel for rural households or discarded as waste, which not only causes a lot of waste of resources, but also pollutes the environment. [0003] The use of green hemp branches to prepare biomass fuel not only achieves environmental protection, but also turns waste into treasure and creates...
