Abstract

The invention discloses a method for processing charcoal from wood chips. The method comprises the following four steps: collection; drying; shaping; and carbonization. Dropped or waste wood chips are collected and subjected to aeration-drying. The dried wood chips are crushed in a crusher into particles. The dried and crushed wood chips are shaped by using a wood chip granulator; the wood chips are wetted before addition into the wood chip granulator; and then extruding and drying are carried out to prepare a rectangular block, and drying temperature is controlled to be 70 to 80 DEG C. The shaped rectangular block is carbonized in a carbonization furnace. Time for carbonization is divided into three periods; the first time period lasts for 1 to 1.2 h, and temperature is maintained at 280 to 320 DEG C; the second time period lasts for 1.2 to 2 h, and temperature is maintained at 280 to 320 DEG C; and the third time period lasts for 6 to 12 h, and temperature is maintained at 460 to 500 DEG C. The method is convenient to operate and has a high wood chip utilization rate.

Description

A kind of method utilizing wood chip to process charcoal
Technical field
The present invention relates to charcoal making, processing technique field, be specifically related to a kind of method utilizing wood chip to process charcoal.
Background technology
Charcoal (charcoal) be timber or wood material through incomplete combustion, or pyrolysis under the condition of isolated air, the Vandyke brown that remains or black porosu solid fuel.
A lot of furniture still manufactures with timber at present, in making processes, can produce a large amount of wood chips.These wood chip major parts go out of use, and do not recycle, and has part to be collected and make wood pellet, as fuel.But still there is the problem be wasted in a large number in wood chip.
Summary of the invention
For the problem of above-mentioned prior art, the invention provides a kind of method utilizing wood chip to process charcoal, the method simple operation,
Utilization ratio is high.To achieve these goals, present invention employs following technical scheme:
Utilize wood chip to process a method for charcoal, comprise collection, drying, moulding and carbonization process, dropping or discarded wood chip air seasoning of collection.Pulverize in the wood chip pulverizer of drying, be ground into particulate state.The wood chip that drying is pulverized is undertaken moulding by wood chip granulator, is drenched by material before putting into, and then carrying out extruding and rectangular block shape thing is made in oven dry, the temperature of oven dry is for controlling as 70-80 DEG C.Carbide furnace carbonization is placed through moulding rectangular block shape thing, carbonization is divided into three time periods, first time period is 1-1.2 hour, temperature remains on 280-320 DEG C, second time period is 1.2-2 hour, and temperature remains on 280-320 DEG C, and the 3rd time period is 6-12 hour, temperature remains on 460-500 DEG C, and then cooling is come out of the stove.
Further, before carbonization by atomizer to wood chip rectangular block shape thing humidification, be that wood chip water content reaches 5-10%.
Beneficial effect: by rational processing step and reasonably time and temperature, by wood chip carbonization, improve wood chip utilization ratio.
