Problems solved by technology

However, there are still major problems in my country's biomass briquette fuel. The processing technology is complicated, difficult, energy-consuming, and costly; the real calorific value, moisture content and ash content of briquette fuel are difficult to control; , easy to accumulate ash, so that the fuel combustion is insufficient, not only pollutes the environment but also corrodes the production equipment; because the raw material for processing and granulation is high-fiber material, the raw material is loose, the size and material are diverse, and it is difficult to press into dense particles when the particles are formed. shape; the rough surface and various shapes of the formed particles also affect the sales volume, these problems seriously restrict the large-scale production of biomass briquettes

Abstract

The invention discloses a preparation method of a novel biomass briquette fuel. The preparation method comprises the following steps: adding wood chips to a crusher, and crushing the wood chips to 40-60 meshes to obtain wood chip powder; adding the wood chip powder, magnesium oxide, manganese mine slag, mica powder and cerium nitrate to a stirrer, adding a proper amount of water, stirring above added materials and water to form a paste; taking the paste, putting the paste in a muffle furnace, and roasting the paste at 700-800DEG C for 2-3h to obtain carbide; uniformly mixing the carbide with petroleum resin and sodium carboxymethylcellulose adhesive slurry, conveying the obtained mixture to a molding machine, and carrying out extrusion molding at 120-140DEG C under 60-80Mpa to obtain a briquette fuel; and drying the briquette fuel, cooling the dried briquette fuel to room temperature, and packaging the cooled briquette fuel to obtain the biomass briquette fuel. The method has the advantages of simple preparation technology, low energy consumption, high production efficiency, high molding rate and low cost; and the prepared biomass fuel has the advantages of small density, high calorific value, less ash, small internal gap, no looseness, good moisture resistance, realization of long-term preservation, and suitableness for industrial production.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a preparation method of a novel biomass briquette fuel. Background technique [0002] For a long time, fossil fuels such as oil, natural gas and coal have been the main energy consumed by human beings, and have made great contributions to the prosperity of human economy, social progress and improvement of living standards. However, since mineral resources such as coal, oil and natural gas are non-renewable, the resources are limited and are facing the danger of being gradually depleted. In recent years, energy and environmental issues have become increasingly prominent, energy prices have continued to rise, and the research and development of bioenergy has become a hot spot around the world. my country is a large agricultural country with abundant biomass resources. However, the utilization rate of crop leftovers is only 20-30%, and about half of the crop waste ...
