Problems solved by technology

[0003] The utilization rate of waste wood in our country is less than 60%, and the utilization rate of waste wood in developed countries has reached more than 80%. It can be seen that the waste of wood resources in our country is very serious. Not only the utilization rate is low, but also the recovery rate and recycling rate are low. Although the wood is recycled, it is directly sent to some small wood processing factories or directly used as firewood

Abstract

The invention discloses a method for preparing machine-made charcoal from waste wood and bamboo and relates to the field of waste bamboo and wood product recycling. The method comprises the followingsteps: (1) smashing the waste wood and bamboo, dissolving into an alkali solution, performing ultrasonic stirring and utilizing deionized water to clean a solution into a neutral state; (2) evenly mixing the waste wood and bamboo powder processed by the alkali solution and cellulase of 0.3% of the weight of the powder and reacting under 32 to 34 DEG C; (3) evenly mixing a reaction product with sorghum straw powder, corn straw powder, glycerol and urea-formaldehyde resin and putting into a high-speed stirring machine to be stirred; (4) utilizing a punching type rod making machine to punch a mixture which is stirred at a high speed into carbon rods; (5) sending the carbon rods into a carbonizing furnace to be carbonized to obtain the machine-made charcoal. By means of the method disclosed bythe invention, the waste wood and bamboo is turned into wealth, and resource reutilization is achieved; not only are resources saved, and waste is avoided, but also environmental friendliness is achieved; the environment is prevented from being polluted by particles generated in a waste bamboo and wood burning process.

Description

Technical field: [0001] The invention relates to the field of reuse of waste bamboo and wood products, in particular to a method for preparing mechanism charcoal from waste wood and bamboo. Background technique: [0002] Mechanism charcoal (machine-made charcoal), also known as machine-made charcoal, fuel sticks, artificial charcoal, regenerated charcoal, smokeless clean charcoal, stick charcoal raw materials from a wide range of sources, rice husk, peanut shells, cotton husks, corn cobs, corn stalks, sorghum Rods, etc. can be used as raw materials to produce stick charcoal, and sawdust, shavings, and bamboo chips are the best. Because the mechanism charcoal is smokeless, odorless and non-toxic, it has been widely used for home heating and barbecue food; in the industrial field, it can be used as industrial raw materials and further processed into activated carbon, etc. Due to its high density, high calorific value, smokeless, odorless, pollution-free, non-explosive and fla...
