preparation example Construction

[0032] The present embodiment provides a kind of preparation method of biomass fuel, and this preparation method comprises the following steps:

[0033] S120: dehydrating and pressing the papermaking pulp residues to obtain dehydrated pulp residues, the dryness of the dehydrated pulp residues being greater than or equal to 40%.

[0034] Papermaking pulp is the solid waste produced in the process of pulp and papermaking in paper mills. Depending on the pulping process, the papermaking rejects in this application can be mechanical pulp rejects, chemical-mechanical pulp rejects, or chemical pulp rejects.

[0035] The dryness of the dehydrated pulp slag is more than 40%, which can reduce the moisture content in the raw material, which is beneficial to the subsequent processing of the raw material, and can effectively control the moisture content in the biomass fuel and improve the performance of the biomass fuel.

[0036]The dryness of dewatered pulp can be: 40%, 45%, 48% or 50%....

example 1

[0090] In terms of mass percentage, the raw materials for the production of biomass fuel include: 35% dehydrated pulp and 65% wood chips. The dehydrated pulp is obtained by dehydrating and pressing the chemical-mechanical pulp, and the dryness of the dehydrated pulp is 40%. Biomass fuel is obtained after screening, drying, cooling and granulation. The moisture content of the biomass fuel was 12%.

Abstract

The invention discloses a biomass fuel and a preparation method of the biomass fuel, the biomass fuel is prepared from the following production raw materials in percentage by mass: 35-45% of dehydrated pulp residue and 55-65% of sawdust, the dehydrated pulp residue is prepared by dehydrating and squeezing papermaking pulp residue, and the dryness of the dehydrated pulp residue is greater than or equal to 40%. By means of the mode, the biomass fuel can promote recycling of resources.

Description

technical field [0001] The application relates to the technical field of biofuels, in particular to biomass fuels and methods for preparing biomass fuels. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste, which is mainly different from fossil fuels. [0003] The research and development of bioenergy technology has become one of the world's major hot topics, and has attracted the attention of governments and scientists around the world. Many foreign bioenergy technologies and devices have reached the level of commercial application. Compared with other biomass energy technologies, biomass pellet fuel technology is easier to achieve large-scale production and use. The convenience of using bioenergy particles is comparable to energy such as gas and oil. Since the 1980s, my country has always listed the research and application of biomass energy utilization technology as a key scient...
