Embodiment 1

[0028] Such as figure 1 As shown, a system for preparing green carbon containing biomass includes: a biomass granulator, a coal granulator, a mixer, and a screw extruder. The biomass granulator is a mechanical device used to process biomass raw materials such as straws, grain husks, and bean husks into biomass granules. And the particle size of the required particles can be adjusted according to the demand. The coal pellet machine is a mechanical device used to process coke, semi-coke or machine-made charcoal into charcoal pellets. And the particle size of the required particles can be adjusted according to the demand. The screw extruder is a mechanical device used to process the mixture of charcoal particles, biomass particles, binder and water into green carbon rods. The main performance parameters of the screw extrusion molding machine are: the axial compression force is greater than 600kN, and the moving speed of the briquetting block is 1500-2500mm / min. The screw extr...

Embodiment 2

[0034] Utilize the method that the system described in embodiment one prepares the green charcoal that contains biomass, comprises the following steps:

[0035] (1) Processing one or more mixtures of coke, semi-coke or machine-made carbon into charcoal particles with a particle size of 15 mm; processing biomass materials into biomass particles with a particle size of 15 mm;

[0036] (2) After the charcoal granules, biomass granules, binder clay and water obtained in step (1) are fully mixed according to the mass ratio of 60:30:10:15, extruded and then dried to obtain the Biomass green carbon, after drying, the moisture of the green carbon is less than 2%.

[0037] In step (2), a screw extrusion molding machine is used to process the mixture of charcoal particles, biomass particles, binding agent, and water. The main performance parameters of the screw extrusion molding machine are: the axial compression force is 600kN, and the briquette The moving speed is 2500mm / min. The ex...

Abstract

The invention belongs to the field of clean energy and particularly relates to a preparation method and system for green carbon containing biomass. The invention particularly discloses the preparation method for the green carbon containing biomass. The preparation method comprises the following steps: (1), processing one or a mixture of more than one of coke, semi coke and sawdust composite charcoal into carbon particles with the particle size of 8-15 mm; processing a biomass material into biomass particles with the particle size of 8-15 mm; (2), sufficiently and uniformly mixing the carbon particles and the biomass particles, which are obtained in the step (1), with a binding agent and water, and drying after extrusion forming so as to obtain the green carbon containing biomass. According to the invention, carbon and the biomass material are prepared into the green carbon according to a ratio, so that the green carbon has the advantages of high heat value, high flammability and high economy.

Description

[0001] The invention belongs to the field of clean energy, and in particular relates to a preparation method and a preparation system of green carbon containing biomass. Background technique [0002] Charcoal is a dark brown or black porous solid fuel that remains after incomplete combustion of wood or woody raw materials, or pyrolysis under air-isolated conditions. It is an impure amorphous carbon that maintains the original structure of the wood and the residual tar in the pores. [0003] As a new type of carbon material, blue carbon is widely used in calcium carbide to gradually replace metallurgical coke due to its characteristics of high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus. , ferroalloy, ferrosilicon, silicon carbide and other products have become an irreplaceable carbon material. Semi-coke (also known as semi-coke, coke), the structure is massive, the particle size is generally abo...
