Problems solved by technology

The current problems of this "post-forming charcoal" are: the use of organic materials (such as cellulose, starch, polyvinyl alcohol, etc.), the production cost is relatively high, the strength is poor, especially the waterproof ability is worse; the use of inorganic materials not only increases The ash content of the product is reduced, and it may also affect the use effect, and the waterproof ability is also relatively poor
A large number of biomass carbon material resources formed by plant straw and solid waste (feces and dead animal carcasses) produced by large-scale animal husbandry are currently not yet available due to the problem of binders. Carry out a large amount of development to become the condition of forming carbon materials, this kind of industry is basically still blank in China

Embodiment 1

[0010] Embodiment 1, grind 1000kg miscellaneous charcoal chips into 40-mesh fine powder with a pulverizer, add 5% lignin, add 120kg of water up and down, stir evenly, and use the currently commonly used screw extrusion rod making machine to manufacture φ60 The hexagonal rod-shaped fuel is then heated at a temperature of 400°C to become a finished biochar product.

[0011] This shaped charcoal has the same combustion performance as the pre-shaped charcoal, and also has the advantage that it will not collapse after being soaked in water for any long time.

Embodiment 2

[0012] Embodiment 2, using the inventor of this patent to apply for the invention patent "method for harmless, resourceful, and reduction treatment of organic waste" (application number: 200510052337.8) with the functions of 'continuous pyrolysis, carbonization, catalysis Equipment with cracking, reduction, gasification and active protection functions' (or other equipment capable of completing the carbonization process) carbonizes cow dung produced in dairy farms into biomass carbon powder (or other biomass carbon powder), adding 20 % washed coal powder and mixed evenly, and then prepared into a mud ball with a papermaking waste liquid concentrate with a solid content of 30%, put it into a mold with a size of 400×400×400, demould and dry before passing through Heat treatment at a temperature of 350°C becomes a post-formed biochar finished product with very good waterproof performance.

[0013] This ultra-large post-formed biochar finished product can be transported in the open...

Embodiment 3

[0014] Embodiment 3, raw material of biomass charcoal powder are the same as embodiment 2. After mixing evenly with 20% anthracite washed coal powder, use the imine method papermaking waste liquid stock solution (solid content: 15%) to make granular molding materials with a diameter of φ30~φ50 on a ball forming plate, and then immediately dry them in a drum The kiln is dried at a temperature not higher than 180°C, and the dried product is then heated at a temperature not lower than 400°C to obtain spherical charcoal with sufficient cold strength, hot strength and thermal stability and good waterproof performance. .

[0015] Since the semi-finished product loses moisture during the drying process of the drum drying kiln, the strength of the spherical semi-finished product will continue to increase and cracks will be automatically eliminated, so the surface of the product is relatively smooth and tidy, and the strength is high, which can meet the needs of various charcoal market...

Abstract

The invention discloses a production method for producing high intensity post forming biomass charcoal, and belongs to the resource and environment technical field. The invention adopts the material which takes lignin or biomass material as the raw material, the substance containing a great amount of lignin components produced during the product processing process acts as adhesive agent, the powder made by the biomass charcoal with fineness of 40 mesh and mesh residue no more than 20 percent, and the high quality refined coal powder with fineness no less than 60 mesh is used according to the proportion of biomass charcoal powder:refined coal powder:adhesive agent of 55 to 95:0 to 40:5 to 45 (percent, all are converted into dehydrated products), the adhesive agent, the biomass charcoal powder and the refined coal powder are processed to be the post forming biomass charcoal semi-finished products having certain shape and size under the condition that the moisture content percentage is suitable for the molding equipment to be molded, and finally are processed to be the post forming biomass charcoal finished products processed through the heating no less than 350 DEG C and the carbonizing treatment.

Description

technical field [0001] The invention discloses a kind of carbon powder suitable for converting various biomass wastes produced in the production process of industry, agriculture, forestry, animal husbandry and other industries into biomass charcoal powder, and how to further process them into charcoal with excellent waterproof performance. The invention discloses a production method of high-strength post-forming biochar, which belongs to the technical field of resources and environment. Background technique [0002] After drying sawdust, peanut husks and rice husks to a certain amount of water, under heating conditions, a rod-shaped fuel with a density of 1.2-1.4 can be produced through a screw extrusion rod-making machine, and then carbonized by dry distillation to obtain good performance. mechanism charcoal. Because its production process is to first compress the raw material and then carbonize it into charcoal, it is customary to call this kind of charcoal "pre-formed ch...
