Embodiment Construction

[0019] The invention provides a method for carbonizing biomass materials, comprising the following steps:

[0020] The first step is to crush the straw and atomize it to keep the water content at 3%-5% of the mass fraction;

[0021] The second step is to extrude the atomized straw and form a ball with a diameter of 30-55mm;

[0022] The third step is to microwave the above-mentioned balls to make the average temperature not lower than 45°C;

[0023] The fourth step is to put the processed pellets into the carbonization furnace for carbonization;

[0024] The fifth step is to maintain the stability of the carbonized pellets at 60-120°C under anaerobic conditions for 15-25 minutes; during this process, calcium carbonate powder is sprayed.

[0025] Preferably, wherein, in the fourth step, the carbonization condition is at 420-540° C., and the residence time is 30-40 minutes.

[0026] In the carbonization treatment method for biomass materials in this embodiment, in the second ...

Abstract

The invention provides a biomass material carbonization treatment method, and belongs to the technical field of biological material treatment. The method comprises the following steps: 1, crushing straws, and carrying out atomization treatment to keep the water content at 3%-5% of the mass fraction; 2, carrying out extrusion forming on the straw obtained after atomization treatment, and forming ball blocks with the diameter ranging from 30 mm to 55 mm; 3, carrying out microwave treatment on the ball blocks to enable the average temperature of the ball blocks to be not lower than 45 DEG C; 4, putting the treated ball blocks into a carbonization furnace, and carbonizing; and 5, keeping the stability of the carbonized ball blocks under the anaerobic condition of 60-120 DEG C for 15-25 minutes; and spraying calcium carbonate powder in the process. According to the method, the biomass utilization rate is high, the energy recovery rate is high, the finished product caking effect is good, and adhesion is not prone to occurring; meanwhile, the carbonization time is short, the requirement for equipment needed by follow-up treatment is low, the production cost is effectively reduced, and the environment-friendly biomass carbon block with the advantages of being high in mechanical strength, good in combustion performance, low in pollution emission and the like is prepared on a large scale.

Description

technical field [0001] The invention relates to a biomass material treatment technology, in particular to a biomass material carbonization treatment method, which belongs to the technical field of straw recycling. Background technique [0002] Biomass particle carbonized fuel is a new type of fuel continuously produced from various biomass through complex processes such as drying, transformation, mixing, molding, and carbonization. It has the same properties as coal and can be used for various burners, biomass High-efficiency, renewable and environmentally friendly biomass fuel for boilers, melting furnaces, biomass power generation, etc. This fuel is internationally certified as zero-pollution fuel. [0003] Biomass is the fourth largest energy source after coal, oil, and natural gas. It has the advantages of cleanness, regeneration, wide distribution, and "net zero emission" of carbon dioxide. Compared with coal, biomass has the advantages of ignition point, ash content, s...
