Mechanism charcoal has the disadvantage of being difficult to ignite in use
[0003] For other easy-to-ignite barbecue charcoal, a mixture of nitrates is added as an oxidizing combustion aid, and NO will be produced when burning X and other harmful gases; the "straw charcoal biomass environmental protection honeycomb ball" disclosed by the Chinese invention patent CN101070499 and the "environmentally friendly and flammable barbecue charcoal and its production method" disclosed by CN101550370A have made explorations and improvements in this regard. The former uses straw charcoal as the main body Because the carbon content of straw charcoal is not high, the calorific value is too low; the latter is added with dry fruit exocarp charcoal powder as a combustion aid, accounting for 2-10% of the total material, the main material is charcoal and bamboo charcoal, and the ignition time is 15-60s , but due to the current scarcity of forest resources, limited sources, high cost, and limited dry fruit exocarp charcoal raw materials
[0004] Chinese invention patent CN103275783A discloses a pure biomass barbecue charcoal and its production method. The pure biomass barbecue charcoal uses wood chips charcoal powder, bamboo chip charcoal powder, cotton stalk charcoal powder and binder as the main raw materials to obtain non-toxic, Pure biomass barbecue charcoal that is safe, environmentally friendly, easy to ignite, and has high calorific value; Environmentally friendly and clean pure biomass barbecue charcoal

Abstract

The invention discloses an environment-friendly and clean pure biomass barbecue charcoal. The environment-friendly and clean pure biomass barbecue charcoal of the present invention uses wood and waste cloth as main raw materials, and various additives are added on this basis. Compared with The traditional pure biomass barbecue charcoal has the following advantages: the main raw materials of the present invention are biomass raw materials, and the raw materials that may cause harm to the human body are screened out during the material selection process; the honeycomb resin adsorption material added in the present invention is a A new type of adsorption material, due to the addition of micro-nano vermiculite powder, the material not only has a strong adsorption effect on PM2.5 particles during the combustion process, but also has enough storage space for these adsorbed small particles to effectively control PM2.5 Particle diffusion; the present invention also adds ultra-high gelatinity protein powder on the basis of the traditional starch binder, the protein powder can not only improve the bonding strength, but also has a good flame retardant effect.

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to an environment-friendly and clean pure biomass barbecue charcoal. Background technique [0002] Zhejiang and other places in my country have already started to produce bamboo charcoal, charcoal and machine-made charcoal, but most of them are produced in earthen kilns, with low technical content and high defective rate. Machine-made charcoal has the disadvantage of being difficult to ignite in use. [0003] For other easy-to-ignite barbecue charcoal, a mixture of nitrates is added as an oxidizing combustion aid, and NO will be produced when burning X and other harmful gases; the "straw charcoal biomass environmental protection honeycomb ball" disclosed by the Chinese invention patent CN101070499 and the "environmentally friendly and flammable barbecue charcoal and its production method" disclosed by CN101550370A have made explorations and improvements in this regard.
