Problems solved by technology

In recent years, the research and application of biomass pellet fuels made of forest processing wastes and straws after crushing and processing has also gradually increased. In terms of the form of biomass briquettes, currently biomass energy is mainly directly extruded. Forming strips, granules or blocks, the application is limited, and storage and handling are difficult; in the molding process, the main method is press molding, which is difficult to press, difficult to process, and low in continuous production; in terms of manufacturing costs, it is Obtaining high-density biomass briquette fuel requires the development of pressing equipment, high input costs, and low production versatility and flexibility

Embodiment Construction

[0024] The present invention is further described below in conjunction with specific embodiment:

[0025] A kind of continuous rolling type biomass molding fuel preparation method of the present invention comprises the following steps:

[0026] The first step, raw material pretreatment, using agricultural waste, lignin and / or oil crop waste as biomass raw material, said agricultural waste including one or more of straw, corn cob, bagasse, algae and water hyacinth A mixture of more than one, the lignin includes one or more of wood blocks, sawdust and bark, and the oil crop waste includes one or one of cottonseed, hempseed and tung tree The above mixture is removed from impurities, then pulverized and sieved with a mesh number of 10 to 100 mesh to obtain raw material powder to be processed;

[0027] The second step, the preparation of the roll-pressed slurry, respectively weighs 80-90% of the raw material powder obtained in the first step, 6-10% of the fiber binder and 2-5% of ...

Abstract

The invention relates to the technical field of biomass briquettes and provides a preparation method of a continuously-rolled biomass briquette. The preparation method comprises the following steps of raw material pretreatment; rolled slurry preparation; rolled slurry viscosity regulation; continuous rolling; and drying and rolling. The treatment steps such as roll compacting, secondary rolling and base material separation can also be carried out according to actual demands. The preparation method has the characteristics of high production efficiency, high universality and low cost, and is convenient and fast for posttreatment.

Description

technical field [0001] The invention relates to the field of biomass briquette fuel, in particular to a continuous rolling type biomass briquette fuel preparation method. Background technique [0002] with the development of economy. Energy and environmental issues have become the focus of global attention. The energy crisis caused by the depletion of traditional fossil energy sources such as coal, oil, and natural gas and the pollution caused by their combustion have become increasingly prominent. It is imminent to develop clean and renewable energy sources. Biomass is a diverse energy resource with a wide range of sources and simple application. It has a good application prospect as an effective alternative energy source. In recent years, the research and application of biomass pellet fuels made of forest processing wastes and straws after crushing and processing has also gradually increased. In terms of the form of biomass briquettes, currently biomass energy is mainly d...
