Technique for producing machine-made charcoal

Abstract

The invention provides a production process of machine-made xylanthrax with short production cycle, high product quality, high added value, which is both clean and friendly to the environment. The production process comprises the steps of A. screening raw materials, selecting wood flour and sawdust produced from deep processing of forestry as raw materials, screening the wood flour and the sawdust through a centrifugal screen, and eliminating bark, branch and other coarse foreign bodies; B. feeding the wood flour and the sawdust screened through the step A to a drying system, drying the wood flour and the sawdust at 250 DEG C with the moisture content of the wood flour and the sawdust no more than 10 percent to facilitate processing and shaping; C. shaping and processing the wood flour and the sawdust in the step B into semi-manufactured goods, and ensuring the heating temperature in a bar forming machine to be not less than 180 DEG C before shaping and processing the wood flour and the saw dust into bars to ensure to provide acceptable finished bars; D. piling up and drying the semi-manufactured goods in the step C in air before the semi-manufactured goods are fed into a furnace for carbonization; E. feeding the semi-manufactured goods in the step D to the gasification decomposing furnace, and cooling the semi-manufactured goods after carbonization in air, thus producing xylanthrax.

Description

technical field [0001] The invention relates to a charcoal production process, in particular to a mechanism charcoal production process. Background technique [0002] Mechanism charcoal is mainly made from sawdust and sawn wood produced by deep processing of forestry wood, and is widely used in food processing, chemical sewage treatment, power generation and other industries. At present, most of the mechanism charcoal production processes in my country adopt the traditional self-combustion earth kiln technology. The carbonized products produced by this method are of low quality and low added value, and the production cycle is long and seriously pollutes the environment. Contents of the invention [0003] The purpose of the present invention is to provide a mechanism charcoal production process with short production cycle, good product quality, high added value, clean and environment-friendly. [0004] To achieve the above object, the technical solution adopted in the pres...
