Embodiment Construction

[0027] The present invention will be described in further detail below by means of specific embodiments:

[0028] The reference signs in the drawings of the description include: carbonization box 1, motor 2, heating channel 3, vacuum suction cup 4, collection box 5, hot gas discharge pipe 6, gas flow channel 7, combustion chamber 8, gas pipe 9, burner nozzle 10 , air guide tube 11, valve 12.

[0029] A kind of technique of wood carbonization of the present invention, step is as follows:

[0030] The first step is cutting, the wood is cut into long strips by cutting machine;

[0031] The second step is to build a carbonization box. A cylindrical copper box is selected as the carbonization box. There is a layer of thermal insulation material on the outside of the carbonization box. A motor is connected to the top of the box. There is a vacuum suction cup on the top of the carbonization box, a collection box is placed under the carbonization box, a spiral hot gas discharge pipe...

Abstract

The invention discloses a wood carbonizing process. The wood carbonizing process comprises the steps of: (1) cutting; (2) carbonizing box building; (3) electrification; (4) wood wrapping; (5) wood fixation; (6) carbonizing; and (7) ventilation. The process not only can prevent excessive temperature in a carbonizing box from causing fire, but also can greatly improve the wood carbonizing efficiency, and improves the wood heating uniformity.

Description

technical field [0001] The present invention belongs to the technical field of B27M1 / 06: by burning or charring wood. Background technique [0002] Wood is mainly composed of cellulose and hemicellulose. Cellulose acts as a skeleton in the wood cell wall, and its chemical properties and supramolecular structure have an important impact on the strength of wood. The hydroxyl groups in cellulose and water molecules can also form hydrogen bonds, and the hydrogen bonds between the hydroxyl groups in different parts directly affect the moisture absorption and desorption process of wood. A large number of hydrogen bonds can improve the strength of wood, reduce hygroscopicity, reduce chemical reactivity, etc., and the hygroscopicity of cellulose directly affects the dimensional stability and strength of the limit. After the wood is carbonized, the concentration of hydroxyl groups is reduced, and the chemical structure undergoes complex changes, so that the hygroscopicity of the woo...
