Machine-made charcoal preparation method

Abstract

The invention relates to a machine-made charcoal preparation method which comprises steps as follows: 1, raw material screening: a mixture of corn ear, corncobs or furfural residues is selected as a raw material; 2, raw material smashing; 3, drying; 4, stick preparation; and 5, carbonization. According to the machine-made charcoal preparation method, the mixture of the corn ear, the corncobs or the furfural residues is taken as the raw material, and by means of the characteristic of higher cellulose of the raw material, cellulose is softened into a molten state at a high temperature, so that a firewood stick is formed through pressing, a binder is omitted, the preparation cost of machine-made charcoal is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to a method for preparing mechanism charcoal, in particular to a method for preparing mechanism charcoal without adding binders. Background technique [0002] Mechanism charcoal is obtained by heating and decomposing mechanism firewood sticks in the carbonization device under the condition of oxygen isolation or a small amount of oxygen flow. Its calorific value is 8000 kcal / kg, and there is no SO2 when it burns. 2 It is a kind of clean fuel without smoke and dust. [0003] However, the existing mechanism charcoal preparation process usually needs to add binders, which greatly increases the cost of mechanism charcoal preparation. In addition, the addition of binders has a certain impact on the health of processors and users. Contents of the invention [0004] In order to solve the problems existing in the prior art, the present invention provides a method for preparing machine-made charcoal, which can avoid the use of adhesives...
